Installing Arch Linux, part 4: Configure the Base System

- by Charles Olsen

At this point I’ve completed the base install of Arch Linux. Now it’s
time to configure and update the system.

The package manager in Arch is called pacman. Pacman is designed to be
small, fast and simple. Its function is similar to other package
managers you’re familiar with, such as Synaptic. It can install,
remove, upgrade and downgrade packages on your system. It also handles
dependencies.

Repositories for pacman are stored on mirrors around the world. Arch
has a script you can run against the mirrorlist file which will test
the mirrors and choose those which are fastest for you to work
from. Once it has set the fastest mirrors, you can update to get the
latest package lists.

Note that all of this is done at the command line. Eventually I’ll
install a GUI desktop, though even then I’ll have to run Pacman from
the command line.

Arch Linux is a rolling release distribution. Ubuntu and Mint, for
example, release a new version of the distro every six months. There
is an upgrade process you can run that will convert your distro to the
new version, or you can wipe it and install a fresh copy of the new
version. If a new package is released after the distro is released,
you probably won’t see the new package until the next version of the
distro is released.

Arch does not release new versions of the distro. You’ll never need to
reinstall to get a new version of Arch, and new packages are made
available to the distribution a short time after they are released
upstream. Whenever you want, you can issue a single command to bring
your entire system up to the latest, bleeding-edge versions. At the
end of this upgrade, your system is completely current.

At this point in the Arch install process you’re running as root. You
need to create a user that does not have root access, for your regular
day-to-day use. Use the adduser command to create a user. It will walk
you through all the information needed, such as login name, full name,
groups, etc.

Now you’re ready to configure ALSA. Use Pacman to install alsa-utils
and alsa-oss, then use alsamixer to set the volume. You can then play
a WAV file — if you hear the voice, sound is configured properly.

The next step is to install the X Window System. This was as far as I
got on my last attempt to install Arch on this PC. When I tried to
install X, I got error messages that I didn’t understand. This time,
it installed with no problem. I probably missed a step last time. If
you decide to install Arch, make sure you follow every step.

Then the instructions explain how to use the lspci command to figure
out which video chipset your machine has. Then you can install the
appropriate video driver for your video card.

Or if you have an Nvidia or ATI graphics card, you may prefer to
install the proprietary driver. I have an Nvidia card, so I used the
proprietary driver.

Then install the input drivers for keyboard and mouse, and you’re
ready to configure X. I got confused in this step. The instructions
said that this section was out of date, and highly recommended I
follow the instructions on the Xorg wiki page instead. I tried that,
but some of the commands did not work.

Even so, after a reboot things started working. Reading through the
instructions again, I think I had missed the step where it told me to
manually start dbus. I had followed the step which added dbus to the
DAEMONS in my /etc/rc.conf file, so it was running after the reboot.

Once again I learned that when you install Arch, follow EVERY STEP.

After X is configured, you can install a desktop environment. As
usual, I went with GNOME. The instructions suggest that you install
gnome and gnome-extra. That results in a LOT of packages getting
installed.

It was after installing gnome and gnome-extra that I thought I had a
problem, but the reboot seemed to fix it. I think next time I try to
install it, I won’t forget to start dbus and it should work even
without the reboot.

Anyway, when I rebooted it gave me the gdm login screen (I had also
added gdm to my daemons). I logged in and the GNOME desktop came up. I
have successfully installed Arch and GNOME. It even uses the optimal
1680×1050 screen resolution.

I still have to install the packages to get the computer to a point
where I can use it, but this is still a huge step for me. I’ve
successfully installed Arch without having to resort to Chakra. I definitely
learned some raw Linux today.

Installing Arch Linux, part 3: Make It So

- by Charles Olsen

As with any other distro, the first step to installing Arch is to
download the ISO for the specific version you want. It’s available in
32-bit and 64-bit versions. You also choose either the Core image
which is good for an offline install, or the Netinstall image which
downloads the latest packages during the install — if you have an
Internet connection, this ensures that you get the absolute freshest
packages.

My test PC has a 64-bit processor with 4GB of RAM, so I chose Arch
64-bit. It also has a DSL Internet connection, so I chose
Netinstall. I downloaded the ISO and burned it to a CD. You can also
write it to a USB stick, or write it to another location which you can
boot from.

Once you boot from the CD, you are greeted by a simple text screen
that informs you that the logins “root” and “arch” have no password,
and to log in with root if you want to do an install.

Once logged in, you’re still on a text screen with a prompt. Text
before the prompt instructs you to run /arch/setup to start the
install. That seems easy enough, unless the command line scares
you. But if you don’t like the CLI, you’d never touch Arch anyway.

While the install is a very manual process, it does a good job of
walking you through it. It provides a text menu that you can move
through with the cursor up/down keys, and press Enter to select your
choice. The tasks are listed in order on the menu.

You may have to configure the network before proceeding — on this PC,
I didn’t have to take any extra steps to get the network interface up.

Next you select the source: the CD or which mirror on the Internet to
pull the packages from. Then set the clock. You can tell it to get the
time from an NTP server.

The next step is to prepare the hard drive. The first choice on the
menu is Auto-Prepare, which will erase and use the entire hard
drive. I chose to partition it manually.

This puts you into cfdisk, a text-based program which you can use to
delete and create partitions. You can create as many partitions as you
want, and set the size and type. The documentation explains this
pretty thoroughly, including how to set up dual boot with Windows if
that’s really what you want. Then you set the mount points, and the
installer will set up the partitions as specified.

The next step is to select packages. First you select package
groups. Base is automatically selected. Base-devel is not selected,
but the instructions suggest that beginners should install it because
they will probably need it later.

Once you’ve selected the groups, you can go down the list and deselect
packages you don’t want. If you don’t know what you’re doing, it’s
best to leave the defaults selected.

Next, install the packages. The selected packages will be downloaded
and installed. This takes just a few minutes, with no further effort
on your part.

When package installation is complete, you can configure your
system. This gets interesting, especially if you’ve only used distros
like Mint, Ubuntu or Mandriva. In Arch, all of the settings are stored
in text files. The first step of configuring your system is to choose
which text editor you want to use: nano, joe or vi. The instructions
suggest that nano is the easiest of these three, but you can choose
another if you’re more familiar with it.

There are a series of text files that store your system
configuration. It may be tempting to skip over this step, but the
documentation states “It is very important at this point to edit, or
at least verify by opening, every configuration file. A common error
is to skip over these critical steps of configuration.”

You start with /etc/rc.conf, which is the principal location for
system configuration. When you open the file, you can see that they
are very well documented — a wealth of comment lines explain what is
contained in the file. There’s also quite a bit of information in the
install instructions.

Once you’ve reviewed the configuration files, you set the root
password and let the system complete the configuration.

The last step to the install is to install the bootloader and verify
the GRUB configuration in /boot/grub/menu.lst. At this point you’ve
installed and configured your Arch Linux base system. It’s time to
reboot. Exit the installer to get back to the prompt, and type reboot.

The system quickly returns to the login prompt. Log in as root with
the password you chose during setup, and you’ll find yourself looking
at a command prompt.

You now have a minimal Arch Linux system installed. You can now
proceed to customize it and build the system that you want.

Installing Arch Linux, part 2: What I Want

As I prepare to install Arch Linux, it’s important for me to know what
I want out of the system. My system will be “finished,” ready to use,
when it has the following packages installed and working:

- Emacs
- Org-mode
- OpenOffice.org
- Firefox
- Audacity
- FileZilla
- Virtualbox
- Dropbox
- GIMP
- Audacity
- Kompozer
- Tomboy or Gnote
- Wine

I usually like to use the same distro on my laptop that I have on my
home PC. This adds a few more requirements. Since I use this laptop
for demos at the Linux 101 SIG meetings, I have to be able to attach
an external monitor and get a good image on the second monitor.

Also, we often visit my stepdaughter and her family. One of the
favorite activities of her three-year-old son is to watch videos with
grandpa on the laptop. My laptop must be able to play DVDs, and also
to play Flash so we can watch videos on YouTube. Otherwise he’ll be a
very disappointed little boy, and I’m determined not to disappoint him
like that. I take my job as grandpa very seriously.

So this adds two more requirements:

- play DVDs
- play Flash

Now that I’ve defined what the finished system will look like, I’m
ready to start the Arch install.

I’d also like to point out that when I do this in Linux Mint, the base
install takes about 20 minutes and covers almost the entire list. A
few minutes in package manager completes the list, except for
Virtualbox. A quick trip to the Virtualbox web site shows how to get
that last package installed. Total time required, from booting the CD
to installing that final package, takes me about 40 minutes.

I’ve tried to install Arch Linux a couple of times already, and
failed both times. I got farther the second time, but I was not able
to get X installed. I tried some troubleshooting, but was not able to
resolve it.

Maybe I missed something in the instructions. The Arch install
instructions, printed out, are 53 pages long. I’m going to try to
follow them very carefully this time.

And so it begins.

Installing Arch Linux, part 1: What Do You Want?

In mintCast episode 41, I mentioned that I want to try installing
other Linux distros, especially Arch Linux.

This is not due to any dissatisfaction with Linux Mint. For anyone
getting started with Linux — or who wants to just install Linux and
get to work — Linux Mint is the best way to go.

It’s like when we moved into this house a few years ago. I don’t know
anything about building a house. I don’t want to know. We chose the
design we wanted, then someone else did all the work to build the
house. Once it was complete, we moved in.

That’s pretty much how I’ve been using Linux. With a distro like Mint,
someone else has done all the work. All you need to do is install it
and get to work. (Or play, if that’s what you want.)

But now I want to build the house. I want to learn where the boards
go, where the pipes are, how everything is connected and why it
works.

There are several approaches one can take for this. Of course there
are web sites that have lessons to help you learn Linux. A couple of
these sites are:

- http://www.linux.org/lessons/
- http://rute.2038bug.com/index.html.gz

These lessons are helpful, but like most people I learn best when I’m
actually doing it. I need to install it, maintain it, and use it, if
I’m going to really learn it.

There are several choices available to someone who wants to follow
this path:

Linux From Scratch (http://www.linuxfromscratch.org/) provides you
with step-by-step instructions for building your own custom Linux
system, entirely from source code. That sounds like the most
comprehensive approach, but I don’t feel like I’m quite ready for
that.

A co-worker suggested Gentoo (http://www.gentoo.org/), and I actually
tried to do a Gentoo install. I definitely learned some new things
about Linux, but did not finish the install.

If you want a taste of Gentoo without doing all the work, you can try
Sabayon Linux (http://www.sabayonlinux.org/). Sabayon is a LiveDVD and
will also do a fairly automated install if you want, bringing up a
finished Gentoo system in minutes instead of hours.

And then there’s Arch Linux (http://www.archlinux.org/). Arch is
designed to be simple, and the install is fairly minimal. Many
Linux distros strive to give you a system that’s ready to use, with
many applications already installed — office suite, web browsers and
other Internet applications, graphics applications, audio/video
applications, games, and more might already be there when you finish
the distro install. This approach allows you to get started quickly.

Arch takes a different approach. Once you have Arch installed, you’re
just getting started. You then need to install the packages needed to
make the system you want. This means your PC will be exactly the
system that you have designed — you’re not working from someone
else’s guess at what you want.

When I first started using Linux, I would have found that very
frustrating — it was helpful to start off with a system that had all
my software already installed.

Now, however, I want to hammer the system together myself. Linux From
Scratch sounds too intimidating just yet, but I think Arch sounds like
a good way to jump in.

And if you don’t want to face the full install process, you can find a
shortcut to installing Arch in the Chakra Project
(http://chakra-project.org/). Chakra is not considered to be a distro
– rather, it’s a distrolet. It’s a LiveCD that can be used to install
Arch Linux with a modified version of KDE.

Linux is all about choice. There are many applications and tools to
choose from. There are several desktops to consider. You can even
choose how much effort you have to put into installing and maintaining
your system. If you can answer the question “What do you want?”, then
you can choose the distro, desktop and tools that are right for
you.

And if tomorrow you have a different answer, there are other distros,
desktops and tools available.

Kinda Linux But More Of An Open Source Posting (as usual lately)

...But linux IS involved! My past as a users' group president in Linux Land is not at all being denied here; I just digress lots. See what you think:

Our pals at LINUX JOURNAL put out this word about the OpenSolaris issue not long ago. It's not an alarmist article; it raises legit questions about whether Oracle values Unix dreadnought Sun's legacy or not. Well, aside from the decision whether or not to continue making certain code chunks widely available through OpenSolaris, Oracle seems to be trumpeting the virtues of the main event clearly enough.

Now there's this. The Illumos initiative may save the day.

My take on all this is that within the OpenSolaris orbit, projects like Nexenta were valuable to Solaris for general Unix PR, as well as for its own products. Nexenta in particular could get Linux people interested in toying with things like ZFS if only due to the Debian tools included, not the least of which is apt-get (and it works!! at least on SOME of my loads). This appeals to my if-it's-Unix-it's-cool ethic. The problem with continuation of the OpenSolaris project would be that Oracle might not be so forthcoming with the big section of proprietary code that's in OpenSolaris and that Oracle now owns. Illumos would solve that quandary if successful. I usually worry about distro forks, but this might be a good one - if one can even call it a fork.

ON A RARE PERSONAL NOTE: Some of you know that I work for an outfit that has a "boonies" location and a "Central" location and that I've been in the boonies for awhile. I AM NOW at Central! Thank you for your discretion.

I GIVE UP (not)

I've been, in piecemeal fashion, giving a review of Eric Raymond's book "The Art Of Unix Programming" and I must confess that it's tough going for someone who codes as little as I do. I at this point only know some basic shell and basic HTML, and to get the most out of Raymond's work, one must code in something more heavyweight such as one of the C's or Perl or even OO things. Raymond, now, will be critical of object-orientation in places but even that would help since most points the book makes are universal (among programmers).

Here's the two places I've been using to read the book online:

faqs.org
catb.org

See? See? I can at least code that.

As Raymond says in one of the intro sections, the book can benefit people that can at least understand that the Unix tradition might have something to teach them. It's not much help if you want to know about kernel application programming interfaces or C programming specifics. Even if you skim the hard parts and only absorb the culture, it can help one understand the Unix/open source ethos, and would be particularly helpful if you're coming from the object-oriented world to a Unix-based project.

I'll keep reading it but for purposes of this blog will move on to other topics - no doubt returning to this one from time to time, if only to rip off another Ken Thompson quote from Raymond.

Two Reviews (short)

In the middle of the other stuff I've promised here, lemme get two things off my chest: my experiences with the Mike Meyers "Passport" series study guide to the CompTIA Security+ certification exam, and a late experience with Fedora 12.

The Meyers series Security+ guide that I picked up used for about 3$ was worth a little more than that, considering that it came with a CD that had two practice exams (Windows-only reader, though). But although it knocked out the cobwebs regarding a few familiarity issues with me, my impression was that the questions (and perhaps the direction of the exam itself, which I've not yet taken) were so obvious that (on a test based solely on the book) one could get 75% without reading the book at all. I've switched to the Greg White book from McGraw-Hill for the current test (201); I'll give an impression of that one when possible.

The other issue I need to note: when downloading Fedora 13, I realized that I'd been doing it on a box with no burner. So I USB2'd an outboard Iomega and chose Brasero and then... stopped in my tracks about 5 minutes later. What's the matter with this picture? No reboot. No requests to install stuff. No error messages. Brasero didn't balk. NOTHING WENT WRONG. I burned the F13 install DVD while doing two other things and not paying attention. PLUS I used the full-install version of the DVD (not the live DVD or CD) to upgrade without disk wipe and there were no problems there, either. Not like a few years back when I trashed at least two installs that way.

People, Fedora is starting to work like a Mac. I'm sure many of you already experienced this or simply wonder what I'm behind about, but my job forces me to use... other stuff from You-Know-Who. So I've never had a lot of time to do testing. Way back when, many OS maintainers on the Linux side were criticized for having an attitude toward users that slammed those who wanted things to work and set up easier. Well, they seem to be getting the point at the Fedora Project, or were never in need of the point in the first place. My compliments to all concerned.

Back to the Eric Raymond book as soon as I get time.

2nd Saturday HLUG: Command Line POWNS you!!

2-4pm today is the standard 2nd Saturday HLUG meeting. We plan to have some examples of some compound
commands using scripting. Also, how to do a backup of a partition using the command line.

HOWEVER, there's a NEW SIG meeting on Saturdays (2nd/4th) from Noon-2pm that's going to focus primarily on Linux shell scripting/CLI. We are using the Linux Phrasebook by Scott Granneman as the guide for the SIG.

Come and enjoy!

This entry was written and posted from my Android phone.

I want to verify that I’ll be able to make blog entries while at the Texas Linux Fest.

I can also make text bold and italic, though it’s not as easy as I’d like.

I also took a picture of my monitor just to see if that works, too.

Today is Document Freedom Day!

From their web site:
Document Freedom Day (DFD) is a global day for document liberation. It will be a day of grassroots effort to educate the public about the importance of Open Document Formats and Open Standards in general.


Go to http://documentfreedom.org/ to learn more. If you've ever had trouble opening a text document or spreadsheet or anything else because you created it in an older version of software (Word/Excel/WordPerfect/Lotus/Powerpoint etc), you understand the need for document freedom.

So, go to http://www.openoffice.org/ to learn more about a FREE (as in, you don't have to pay for at AND all the freedoms from the LGPL.

If you're STILL not clear on what all this "Document Freedom" stuff is about, there' still time to stop by the HLUG Linux Workshop (6-9pm tonight at HAL-PC) OR to call in to Technology Bytes tonight from 8-10pm on KPFT FM 90.1

2nd Saturday HLUG: Command Line Power of the Ancient Wizards!!

Today the discussion will focus around the CLI (Command Line Interface) of Linux. It's going to be all about Shell Scripting. For those not aware, the command line (the thing that looks like a DOS prompt? No pictures, just text commands you have to type in) in Linux is called Bash (short for Bourne Again Shell), which is an improvement on the original Unix Shell. I'm not sure how much history Ron will go into today.

In any event, gaining True *nix Wizardry begins with a basic understanding of Shell scripting. There's a tremendous amount of flexibility, power and convenience that can be found at the CLI. Ron will start to unveil those mysteries today! It's like your first year at Hogwarts, or the Jedi Academy. Or something.

Another note, the rumor is the NEXT Saturday HLUG meeting (two weeks from today; 4th Saturday) will be for paid HAL-PC members only and may or may not include DOOR PRIZES. That's something HAL-PC SIGS have been famous for over the years. I've got a copy of Office 2003 Pro floating around, among other things, that I got as a HAL door prize. More details on that as they become available.

Expecto Patronum!!

2. Meetup: Rick
3. Linked In: Jorid, Joey

What we do not have time for this week, can be continued

HLUG Linux Workshop: It's already started!!

It's Wednesday night, so you should know the drill by now. Get thee to HAL-PC and partake of the Linux Workshop goodness! Get help with thine own vexing Linux questions! Assist others with issues that, verily, cause them to be vexed.

Basically, we're trying to avoid and eliminate all things "vexing". 6-9pm. Dinner/socializing afterwards, to be announced at the Workshop.

ALSO! Do NOT forget about Technology Bytes. 8-10pm on KPFT or live streamed over the internet(s), if you're not in the Houston area. Speaking of Technology Bytes, if you didn't attend their last Geek Gathering, here's what you missed. The lovely woman in the first picture is Victoria Leigh, model/photographer/makeup artist. The smiling man next to her is her husband. He works for Ubuntu, dealing with OpenOffice.org bugs. See what Linux can do for you? I'm just saying. Don't blame me, it's not like I didn't tell you! The Geek Gathering's are the first Friday of every month at The Coffeegroundz.

That is all.

What IS the HLUG Linux Workshop?

I'm glad you asked! The Wednesday Night Workshop (WNW...not to be confused with Neverwinter Nights...NWN) is where people with questions about, trouble with or interest in Linux get together to work it all out! Bring your computer/keyboard/mouse and we'll supply the monitor/power/network connection (wired and WiFi) and get things taken care of!

Trying to install Linux? We can help! Got Linux installed, but can't get a piece of hardware working? We can help! Need to get a certain piece of software installed or configured on your Linux install? We can help! Want to dump your other OS and replace it with Linux? We can help!

Wednesday nights, 6-9pm at HAL-PC Global HQ!! Followed by dinner...somewhere.

ALSO! Be sure to tune in to Technology Bytes Radio, ALSO Wednesday night from 8-10pm. And don't miss the Geek Gathering, this Friday at The Coffeegroundz!

2 views of last Saturday's Samba SIG

What'd you miss last Saturday?

Rick Archbald says:
W/o Rob't spotswood (sick), the Samba SIG didn't make much progress on
the mail server project. We did convince ourselves that KirraMail
doesn't install easily & isn't worth fighting w/ for having a 2nd mail
server on the network. We also discovered that the last release of
VMware 2.0 is useless. If we knew that either VBox or VMware would
save the complete state, including RAM, of a VM (this may be a
"stupid" question), then we could run Kirra in a VM, & have it have
some continuity.


Ron Lyle offers this view:
We built a vmware KerraMail mail server just to see if we could set up a mail server. The samba SIG went well and I found thanks to Rick, some Google special searches under UNIX (google/linux, google/gov, and google/bsd) We learned that vmware doesn't do snapshots and virtual box does.


They'll be back at it on the 3rd Saturday of the month. That's the 19th for those scoring at home.

by HLUG Kojo (noreply@blogger.com) at March 10, 2010 05:06 PM

Samba: TODAY from 2-4!!

The quest to build an ISP-grade mail server continues! Stop by HAL-PC to join in on the fun and learning! Tech up!!

News Item

It appears that Oracle is being a good neighbor with respect to open source-ing some things, or rather continuing to (subsequent to the Sun acquisition). This story indicates that the OpenSolaris project will undergo basically no change and that a commitment is being made to its future. Certainly this will benefit Oracle by the encouraging of experimentation with file systems and software features now under its control (like ZFS, the combined file system and LVM) but I see the continuing maintenance and free availability of any decent (-nix-oid) system as a good thing. In the words of the nerd-rock band DEVO, "duty now for the future"!

MythTV walkthrough – Software/Backend

In response to my own part one video on MythTV I thought I would link to the last 5 parts of the series I recorded bringing you from bare metal to a watching TV in about an hour.

And here is the setups specifically for configuring the MythTV backend.

The widescreen videos don’t really line up right now with our Wordpress theme but I think giving good quality is worth it. Click on the videos to be redirected to my youtube channel and you can watch the HD versions there.

The Anti-Book-Review Times Two

Since I have two computing-related books to review and have not finished them yet, I'll let you in on the locations thereof. Both have online free versions in various places; here's some that I know about.

THE ART OF UNIX PROGRAMMING by Eric Raymond

Mr. Raymond has been around programming since way the hell back and offers this best-practices book that can do at least three things: document the early computing culture, acclimatize programmers to the Unix world that may have come from other environments and focus the efforts of other programmers who are Unix-native. Here's one of the book's many online homes:

NMAP NETWORK SCANNING
The Official Nmap Project Guide to Network Discovery and Security Scanning
by Gordon “Fyodor” Lyon

Living at the venerable nmap.org, this is a less-than-complete version (buy it to get everything) but this version is merely lacking in all examples and extended discussions. All the basics are here. The tool's free and the bad guys use it, too, so if you're a White Hat Wannabe like me, you have no choice but to get right with Nmap.

So now, let's see if I can finish these before you do - and before you scoop me on your blog.

SAMBA SIG Updates

Here's what you missed last Saturday at the SAMBA SIG (and yes, I DO alternate my capitalization of "Samba". Sue me) We're continuing our goal of building an ISP-Grade mail server.

Today we got the spam script working and spammed our new server. Over a 100 MB
connection, it took about 14.5 minutes to send 10,000 messages. During that
time, CPU usage on the mail server shoot up to around 90%. However, even
during the storm, the webmail interface was still responsive. Nevertheless, it
showed that we need anti-spam measures.

In order to get the spam script running, we used another machine, then booted
with Knoppix 6.0.1 and installed sendmail (what the script requires). Knoppix
5.3.1 would not work with sendmail for some reason.

In the next meeting, we need to try to add some polish to our testing mail
server. The current list of items to address is:

1) Anti-spam measures and anti-virus measures. Current plans are to use
Amavis. It will be interesting to see what the load is on the server if we
repeat the spam storm with the measures in place.

2) Implement quotas. We can't have one user fill up the hard drive.

3) Change the squirrelmail url to something better and more standard, such as
webmail.samba.lan.

4) Install a list manager. Mailman has been suggested.

It is likely it will take more than one meeting to accomplish all this.


Join in in two weeks!

Samba SIG Updates: "In our last episode, our heroes..."

Here are the notes from the February first Saturday Samba SIG meeting. Remember, the third Saturday is THIS Saturday! 2-4pm at HAL-PC in SIG Room C.

Pardon the bad formatting, I'm in a bit of a time crunch. I'll try to beautify it later.


Today work continued on the mailserver. Robert attempted to set up three interfaces to manage the users without resorting to raw sql statement and got two of them working. GRSoft MailManager is working and is a web based front end. Ispwebadmin we never got working. The final one is a bash script by manu that, although limited, works just fine. While this one won't be used much, it does leave open the possibility for a mass setup of email accounts with a little hacking of the script.


We also got squirrelmail working too. Next up is one of two things, to be decided on in the coming two weeks:


1) Set up a test network with some kirramail servers to test out the postfix mail server and make sure everything is working.

2) Set up virus and spam filtering on the new mailserver. We've got a volunteer to be the evil spammer. He will try to counter our measures to block spam (on the test network). He will have the advantage on knowing what countermeasures we are using.



Come join in !!

Samba SIG Updates: "A long time ago, on a server far, far away..."

This coming Saturday is the 3rd Saturday of the month, which means the Samba & Network Admin SIG will be going on at HAL-PC from 2-4pm.

Luckily for all of us, Robert Spotswood has been good enough to condense the activity from prior meetings. You can subscribe to the Samba SIG email list to get these announcements, but I'll also be posting them here. Here then, are the notes from the January meetings.
Subject: update for 01/09/10
Date: Monday 11 January 2010
From: Robert S
To: "SambaSIG Announce"

Rick and I continued to work through the Postfix/Dovecot tutorial. We have now completed it through the authenticated SMTP page. At this point we have a mail server that can send and receive emails, although so far we have only tested it via telnet. If telnet works, so should any regular email client. However, in doing tests that weren't in the tutorial, we discovered a problem with testing it further.

Gunn (at least I think this is his doing) has wisely chosen to block all outbound port 25 connections for most of HAL. This means we can't send email outside HAL to accounts we own. On the flip side, it also means a spammer can't enter HAL, use one of the public computers and leave HAL with a black eye. A good trade-off IMHO. The solution Rick and I came up with to play with the email server further is to set up our own mini-Internet with another email server (or two!). We can use the lab machines next door to SIG C, two of which have DVD drives and removable HD trays. The plan is to get two HDs, put them in removable trays, plug the trays into the two machines, install KirraMail on them, and set them up as other temporary email servers with fake domains so we can send and recieve email from other mail servers. We will need a couple of old HD's donated. We also will need to set up a DNS server for all of them to use, so the email servers can find the MX servers. Rick suggested Dell could write the config and zone files, and all we have to do is plug in the correct IPs once we know them. Can you do it Dell?

We will also have to adjust the resolv.conf on the two (or three) email servers to point to the DNS server, and maybe the client test machines. Since all the other computers get their DNS info via DHCP, this shouldn't cause any
problems with the rest of HAL while we do this. We can also use this setup for trying the other email server configs we will
be looking at.

Questions? Comments?

And THEN!!!

From: Robert S
Date: Sat, Jan 30, 2010 at 10:32 PM
Subject: last meeting (01/15/10)
To: SambaSIG Announce

This time Dell, with just a little assistance from the crowd, set up a DNS server template with three "fake" domains. This is necessary to begin building an email server test environment. The reasons we need this were discussed in the 01/09/2010 update. At this point, it is complete and all we may have to do is change a 6 IP addresses once we know what they are, and reload the config. One HD has been donated to Rick to get an install from his KirraMail CD. We could use another. Anyone? In the meantime, this is enough to being testing the Postfix/Dovecot setup we have, which will hopefully happen next meeting.

We also have a DHCP failover lab coming up, but nothing is scheduled yet.
There you have it, notes from the January meetings. The first Saturday of February will be posted soon. Stay tuned!

HLUG Video Archives

If you look in the upper-left hand corner (look now!), you'll see a link to our Video Archive. For those too lazy to look (you know who you are), the direct link is: http://video.houstonlinux.org/

They haven't been updated in quite awhile, but the information is STILL quite interesting. Everything from an overview of Linux (which has surely changed since the video was made) to TCP/IP networking basics (an evergreen topic) to the History of HLUG (and what a history it is!)

So, if you're not able to make it to a meeting or you just want to know more about a topic, be sure to check out our video archive. We hope to start recording our meetings again at some point in the future, but we don't know exactly WHEN that's going to happen.

Also, don't forget about the Wednesday Night H-Town Tech Extravaganza! More on that later.

Well, happy December and stuff!

First, some housekeeping details: you may have noticed that I don't update quite as often as in the past. I am no longer an officeholder at the Houston Area League of PC Users, but that organization continues improvement efforts and reorganization as we speak, or type (check their site for the latest).

Second, I continue to press onward with technological interests such as the open source movement, computer security, backup methodology, unusual internet content, publishing, et cetera.

Thirdly, I'll use this blog to prognosticate and pass on interesting tidbits to whomever reads this blog, as well as for my own use (as an online link repository, for example).

Upcoming topics here may include...

The Nmap book by the Nmap guy
BackTrack 4 final release changes and progress
Recent TRK changes and improvements
Adventures In Learning Perl (hopefully without attacking competing languages much)
Adventures In Deleted File Recovery (or Oops I Did It Again, and in a different oddball file format this time)

So stay tuned and let's see what I come up with.

I've made a momentous discovery.

Although I am mostly ashamed at having been talked into establishing a Facebook account, I have found something about that system that's actually socially redeeming. Somebody established "INTERCAL Enthusiasts" on FB. I'm not even a proper programmer and this is funny to me:

Here is the "Hello, world" program in INTERCAL:

DO ,1 - #13
PLEASE DO ,1 SUB #1 - #234
DO ,1 SUB #2 - #112
DO ,1 SUB #3 - #112

Tech Fest A Resounding Success

About a half-dozen denizens of Hal were present at the "users groups" table that Tech Fest afforded us, and the one other group that showed, the Houston Java Users Group. As for us, we got over six sheets' worth of email contacts and I'd guess that it totals to over 100 people expressing interest (Chris or Jim Ward may have the sheets and therefore could give an accurate count).

The scene was mostly .net developers but about 20% of the subjects were applicable to other things. It was well attended by head hunters, too; I'll be there next year.

NEWS

HAL-PC FUNDRAISER POSTPONED
Due to various time constraints, the Sept. 7th BBQ has been put off at least 6-8 weeks. Stay tuned to the Hal-PC site for re-scheduling notices.
LINUX 101 ROCKS YOUR SOCKS
I dropped into the Linux 101 SIG (special interest group) meeting after the executive committee broke up for the night (and John Davis and me had finished talking about the Houston Punk scene) and saw that they are drawing about the healthy half-dozen or so that my SIG used to draw (I think they're doing OK as well). And I'm not just pimping them because they (Linux 101, 1st Tue. of Month, 7pm, Hal-PC) looked at the latest Linux Mint. But that helped.

New HLUG SIG Leader Elected

As I understand it, we have a new leader: Ron Lyle! Congratulations to he who stepped up to the plate. An election was held and Ron won (this would have been last Saturday; I was... let's just say "on call"). So under Ron's direction, meetings continue as the masthead of this blog states: every second and fourth Saturday, 2pm at Hal.

In other news, it's been suggested to me (by Jim Ward) that the Presidency of HLUG, as opposed to the Special Interest Group leadership position for the scheduled time slot, become a separate position (I think he had in mind an emeritus capacity). It seems doable to consider me a publicity figurehead at least in order to continue with this blog and other promotional activities, in spite of my employer's shift changes and their effects, which take me out of the scheduled flow. Also, having a President (in addition to a SIG Leader) maintains a connection with the structure of HLUG that originally merged with Hal about ten years ago; continuity is good.

I agree to such an arrangement if it's amenable to the new leader and the membership. Also, I'll be describing/pimping/reviewing the meetings here into the future (and naturally able to review something when I am not called upon to work Saturday and therefore could show up at the meeting).

See some of you at the Hal Board meeting tomorrow night.

Well Howdy

Labor Day BBQ Plans Forming:
Watch the Hal-PC home page for details on the upcoming feedfest. It's a volunteer appreciation event and is being put together as we speak (type).

Saturday HLUG meet:
The 22nd is the second meeting date of the month and so far, there's no new President. I may be able to make it in order to help facilitate an election but if I'm not there, I give my blessing to a quorum present. Here's my suggestion for upcoming topics that I think would make good presentations ---

VMware
Virtual Box
VMware VS Virtual Box
IPv6
current developments in TRK (may have an expert for this)
current developments at insecure.org (I'm looking into this)

More Thoughts On Unconfiguration (if that's a word):
Previously (under the rubric "Off-Topic") I posted on Mac OS 9.1's ability to wipe settings and prefs in a way that distantly suggested sys-unconfig in Solaris. The distant relationship is that one is able to change some things without reinstalling the whole shebang (which can take many, many hours with some of Sun's products as we know). Can someone at a future meeting tell me if this is now possible in some Linux or other? I don't mind admitting that I don't know.
