Update to my linux on the desktop plan ...

Added on by Ray Insalaco.
Well Ubuntu 7.04 ran great for me right up until the day before it was released. There was an update to NetworkManager the day before the final release and it hammered my networking. After installing the update I lost both my wired and wireless networking. A couple of days after the final release I downloaded the final release ISO and installed it. Still no networking on my notebook. That was the end of Linux on my notebook. Without networking computers are not very useful. It looks like I will be running Windows on my notebook for awhile. I have not decided when I will download a new distro and give Linux another try.

At work I have been trying to replace some Windows boxes with Linux without much luck. We have too many custom applications that I have not been able to get running under Linux. Something that I have been able to replace with good success has been servers. I contacted RedHat about getting an evaluation copy of their Red Hat Enterprise Linux 5 to test for replacing some file and print servers. I was stunned after filling out their online form and getting an email telling me that someone would contact me within the next five business days about the evaluation. That was it, no link to download an ISO or anything. It ended up being three weeks before someone contacted me to see if I was still interested in evaluating Red Hat Enterprise Linux 5. By that point I had decided to go with Ubuntu 6.06 LTS. I do not know how Red Hat plans to grow things if it takes that long to get evaluation copies of their software.

One of the bad things as far as Linux is concerned is that is nice for everything on my notebook to just work. There are some things that I have never been able to get working under Ubuntu or SuSE. I guess that covers most of what has going on in this area.

Feisty Fawn Update ...

Added on by Ray Insalaco.
Well as I continue to use Feisty I am running into the standard problems with using beta software. The day after my last post there was an update to killed Beryl. It took about four days before there was an update that fixed the problem with Beryl, so all is good again in the 3D desktop world. There where 119 updates today, and one of them is a rather exciting update. I did not have Compiz installed before the update, but it was installed with the update along with the desktop-effects package that is included with SLED 10. It look like Compiz may be installed with Feisty after all in the finally release. Mark Shuttleworth posted in a recent blog posting that nether Compiz or Beryl where ready to be included in the final release. I don't know what this means to the debate about including proprietary video drivers by default in the next release, but if it make things work better and easier to setup, than I am all for it.

General Update ...

Added on by Ray Insalaco.
Well it has been a little too long since my last post, so here is a quick update. I have been testing SuSE Linux Enterprise Desktop for the last couple of weeks on my work notebook. We are trying to move some of our Windows desktops to Linux to reduce cost. We are already using NetWare so we do have support from Novell. The problem is, I am a Linux user and I find SLED 10 to be difficult to work with at times. There are still too many hardware issues with SLED that are not there with other Linux distributions. I added a second hard drive to my home notebook to see if SLED would work with that hardware better, but still had problems with sound cards and the battery meter. These things have just work for the last two Ubuntu releases, so it looks like I may go that route at work.

I upgraded my home notebook the Feisty Fawn two weeks ago, and I have two say that I love it. I also installed Beryl and it has worked very good. That project has come a long way since the last time I tried it. I did run into two small problems with Feisty. I could not get VMware Workstation 5.5 to install and every time I tried to install anything with CrossOver Office the install would fail. I upgraded both applications and that seems to have fixed the problems.

Well that is all for now, but there should be something else this week. We have a full dance card this week. We are replacing one server and twenty-eight workstations in three days. That should be fun ...

Simple Linux Backup with SCP and TAR

Added on by Ray Insalaco.
I ran into a problem this week when I tried to pull a file off of a backup and found out that I could not read any of the backup tapes that I had. I was using Dump to create the backups and when I tried to access them with Restore I got the error message that the tape was not a dump tape. I had tested this before I put the server into place, but something has changed in the last two months. I decided to change to a different method of creating backups. I am now going to tar the server and then use scp to move the tar file to a second server that is located off site.

Lets start with setting the machines up so that we can transfer files between the two servers without being prompted for a password. For this posting server1 will be the server that is being backed up and server2 will be the server that we are sending the backup to.

Configure the Client (server1)
Create the client key without a password:
[root@server1 /]# ssh-keygen -t dsa
Generating public/private dsa key pair.
Enter file in which to save the key [/root/.ssh/id_dsa]:
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_dsa
Your public key has been saved in /root/.ssh/id_dsa.pub
The key fingerprint is 00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:root@server1


Lets take a look at the key:
[root@server1 /]# cd ~/.shh
[root@server1 /]# ls
id_dsa id_dsa.pub known_hosts


Copy the key to the server that we are going to copy the backup to:
[root@server1 /]# scp -r id_dsa.pub root@server1:key-temp.pub


Configure the server (server2)
Lets make a .ssh directory if the directory does not exist:
[root@server2:~#] mkdir .ssh
[root@server2:~#] chmod 700 .ssh
[root@server2:~#] cd .ssh


Add the key for the client to the authorized keys:
[root@server2:~#] cat ~/key-temp.pub >> authorized_keys
[root@server2:~#] rm ~/key-temp.pub


You should now be able to use ssh and scp from serve1 to server2 without being prompted for a password.

From here I had to create the script for creating the tar file of server1 and then copying it to server2. I created a directory called backup to hold my script and the MySQL backups. So on server1 we are going to create the directory and the script:
[root@server1: /#] cd /
[root@server1: /#] mkdir /backup
[root@server1: /#] cd /backup
[root@server1: /#] nano backup.sh


Now the script:
#!/bin/sh

# Define the variables for later use:
BACKUPFILE=backup-$(date +%Y%m%d)
OLDFILE=backup-$(date --date='7 day ago' +%Y%m%d) # We are keeping 7 days of databases dumps.
EXCLUDES="--exclude=/proc --exclude=/lost+found --exclude=/sys --exclude=/media --exclude=$BACKUPFILE.tgz"
BACKUPDIR=/
COPYTO=root@server2:/root/.


# Backup the MySQL Databases:
mysqldump -uroot --opt databasename1 > /backup/databasename1-$BACKUPFILE.sql
mysqldump -uroot --opt databasename2 > /backup/databasename2-$BACKUPFILE.sql


# Create the tar file:
tar cvpzf $BACKUPFILE.tgz $EXCLUDES $BACKUPDIR


# Upload the tar file:
scp -rp $BACKUPFILE.tgz $COPYTO


# Remove the backup file:
rm $BACKUPFILE.tgz
rm /backup/databasename1-$OLDFILE.sql
rm /backup/databasename2-$OLDFILE.sql


You should now be able to backup server1 with the command:
[root@server1: /#] sh /backup/backup.sh

Just want to say thanks to David for his demo at the last ECLUG meeting, because it gave me the point to jump off at.

All of the information here was taken from a pair of Impress presentations that David had made for the presentation.

The next meeting is scheduled for January 4th at 7PM at NFA. At this meeting Dave is going to be doing a presentation on Bash. The pre-meeting dinner will most likely be at Dillans in Norwich starting at 6PM.

SUSE Linux 10 vs. Ubuntu Edgy 6.10

Added on by Ray Insalaco.
Well I have spent the last week playing with both SLED 10 and Edgy. Both of these distributions are excellent and will make any user happy, however they are not without faults.

SLED 10: The first thing that you see is WOW, this is an incredible looking distribution. It would seem that Novell has spend lots of time making SLED look great. The default software that is installed is good and for most users it will have everything that you need. I like the way that they have done the start panel, although it took some getting used to. I was not so crazy about the new layout that they used for GNOME. The first thing I did was change GNOME back to the more standard layout. It would have been nice if there had been an option during the install for the new or old layout. The install did not have any problems with me hardware, other than the standard problem with sound capture with my sound card, which is an HDA Intel card that has not worked with anything yet. Novell really needs to remove that bastard of a configuration mess called YAST. This has got to be the worst configuration tools every used. It can do just about anything, if you have the four hours needed to find what you are looking for. The package management tools within YAST are not as good as apt or yum, and should be replaced with one of them as the default package manager.

Ubuntu Edgy: Mark Shuttleworth made a posting in his blog recently that “Pretty” is a feature. Well they are still off the mark with this release on that count. For all the changes and growth that Ubuntu has made in the short amount of time that it has been around, the looks just have not kept up with the rest of the changes. The color scheme is starting to get dated, and the graphics have not changed much. After spending some time on the GNOME art site things started to look much better. The default install includes an excellent selection of software for a distribution that comes on one CD. The time between Edgy and Dapper was rather short so as one would expect there are no major changes. Most of the packages are simple updated from the previous release. There where really only two big changes that I have found. Edgy is now using a generic kernel that replaces the K7 and i686 kernel from past distributions. The other change is with Nautilus, it is not nearly as stable as in past releases. Edgy uses apt for its package management, and after making a few changes to the source list there is pretty much nothing that can not be install quick and easy.

Conclusion: Both of these distribution are excellent and will make the user glad they are not using Windows. It really comes down to personnel preference. I personally have come to prefer Ubuntu because of its excellent package management tools and general ease of use. I started out using SUSE and never did learn to like YAST, although I did come to a basic understanding with it. In the end I would have to give Ubuntu the edge in both community and pace of change.

ECLUG Meeting for November

Added on by Ray Insalaco.
At last nights LUG meeting I did a presentation on setting up and configuring OpenVPN server. We did a Linux server and then setup both a Linux and Windows client. There were a couple of problems that came up which then let us do some trouble shooting of the server. That was pretty much it for the meeting as the presentation was a little over and hour and a half long.

The next meeting is scheduled for December 6th at 7PM at NFA. At this meeting Dave is going to be doing a presentation on Bash. The pre-meeting dinner will most likely be at Dillans in Norwich starting at 6PM.

ECLUG Meeting for September

Added on by Ray Insalaco.
Dave Desrosiers had some goods to hand out before starting his presentation on installing Linux on a USB key. We spent about one and a half hours going over some of the distributions designed to run from USB keys and what they can be used for. It was a very good demo, and we found out that my Alienware notebook was totally useless. Any time I tried to boot from a USB key the notebook locks on of all things, scanning for USB devices. The presentation has been posted as a PDF file.

Some of the distributions talked about were:


Also displayed during the meeting where some options for how to encrypt your USB key so that is still accessible from Linux and Windows with TrueCrypt. Dave showed us a USB key that he has for everyday use that is protected with TrueCrypt. When it is used inserted into a Windows box it autoruns to display the login for TrueCrypt, and then displays a menu with any Portable Apps that are installed on the key. Many of the Portable Apps are packaged in a way that allows them to also run under Linux.

Before ending the meeting Devin Duval talked about XGL and compiz eye candy. He is going to be doing a demo of this at the next meeting. I am not sure if he will be covering installation and configuration.

When the floor was opened at the end of the meeting there was some discussion about the Ultimate Boot CD and some of the software packages that could be useful for a public Library. We have someone who is looking a setting up three stations a his public library and they have no real budget for the project, so he is looking at what can be done using Linux.

The next meeting is scheduled for October 4th at 7PM at NFA. The pre-meeting dinner will most likely be at Dillans in Norwich starting at 6PM.

NASlite Boot Disk

Added on by Ray Insalaco.
I was playing with NASlite the other day and could not create the boot disk by the method explained on their web site. The bootable disk is a 1722k disk. After some digging I found some something that worked. Note: This was only tested on Ubuntu 6.06.

setfdprm /dev/fd0 1722/1440
fdformat -n /dev/fd0
dd if="image name here" of=/dev/fd0

ECLUG Meeting for July

Added on by Ray Insalaco.
The July Lug meeting was last night. The main topic of discussion for tonight had to do with printers and trouble shooting them. There were a couple of problems that members were having so this was a good time to talk about ways of correcting some of the more common printing problems.

The second part of the meeting was about server configuration, and if you need, or should, install a GUI on a server. I have to say I am on the side that can not see why you would, or should install a GUI on a server. The problem with that is you might as well try to get everyone to say ether Gnome or KDE is the better GUI. Reality is that they both have there own strong points and weak points.

We did start to talk about holding elections, but that was tabled pretty quick. There was a general discussion about updating the bylaws before holding elections.

For anyone interested the ECLUG, Eastern Connecticut Linux User Group, meets the first Wednesday of each month in Norwich, CT at NFA.

OpenVPN Setup (Updated 11/02/2006)

Added on by Ray Insalaco.
I had two machines that I needed to install OpenVPN on yesterday, so I figured I would post the steps required to get them up and running. The servers where both running Ubuntu 6.06.

Here are the quick and dirty steps:
sudo apt-get install openvpn openssl

cd /usr/share/doc/openvpn/examples
sudo cp -R easy-rsa/ /etc/openvpn

cd /etc/openvpn/easy-rsa
sudo . ./vars
sudo ./clean-all
sudo ./build-ca
Answer the questions to create the key

Now we need to create the server key:
sudo ./build-key-server server
Again answer the questions to customize the key. You can use the defaults if you want and just enter the server name when asked. The name is required, if you do not enter a name the key will be a zero length and will not work. The error message if not all that straight forward, it only says the server failed to start.

Now we need to create the client keys:
sudo ./build-key 'name of key'
Again answer the questions to customize the key. You can use the defaults if you want and just enter the computer name when asked. I like to use the name of the computer the key is for, because it makes it easier to keep track of the keys if you need to remove one. The name is required, if you do not enter a name the key will be a zero length and will not work. The error message if not all that straight forward, it only says the server failed to start.

Now we create the Diffie-Hellman parameters:
sudo ./build-dh

When we pass the keys to the clients we need to distribute the following keys to each client:
ca.crt goes to the client and the server.
ca.key goes to the key signing machine only, which we set this on to be.
dh{n}.pem goes to the server only.
server.crt goes to the server only.
server.key goes to the server only.
.crt goes to the client only.
.key goes to the client only.

The last thing to do on the server is create the configuration file: (view sample)
sudo vi /etc/openvpn/server.conf

Restart the service and the server is done.
sudo /etc/init.d/openvpn restart

Next we have to create the configuration file for the client: (view sample)
This file needs to be saved in the same directory as the keys. On windows the configuration file should be saved with a .ovpn extension. Just double-click this file to establish the connection. Establish the connection on *nix or Windows run openvpn [client config file]. With a little luck you should be connected now.

VMware Server Setup

Added on by Ray Insalaco.
After another night of getting called do to server failure, I have decided make some changes to the servers at work. Currently we have two Windows 2000 servers that are running most of the company. The basic problem is that one program, Track-It!, started to generate error and took down the server it was running on. It is installed on the Primary Domain controller, yes I know that is a bad idea, which in turn took the Backup Domain controller down. So when you only have two servers, that is the whole show. This is the problem with only having two servers, they both wear too many hats.

The end result of all of this is that we were going to upgrade to Windows 2003 EE R2 during the July shutdown. This version allows you to run up to four virtual servers on one server. So now we are testing using VMware Server on ubuntu, with all the Windows servers running as virtual machines on top. If this works out good, we will look at maybe moving to VMware ESX next year, because it just is not in the budget for this year. I still have to workout how the backups are going to run. Right now I am looking at the Amanda Enterprise Edition backup software. This will also have to be tested before we put everything in place. I have been using ubuntu on my home server, which does get almost as much use as some of the servers at work, without ever having a crash.

Hardware:
Dell Poweredge 4400
Dual Processer 2.2 GHz
5 GB of memory

Server 1 will be running 4 Windows 2003 EE servers.
Server 2 will be running 1 Windows 2003 EE server, 1 Netware 3.12 server and 2 Windows XP desktops.

Server Setup:
Install ubuntu server on the hardware.
Edit the source list for apt to enable all the software repositories.

Install the other needed packages:
sudo apt-get update
sudo apt-get install linux-686 linux-headers-686 linux-image-686
sudo apt-get install build-essential gcc g++ make fakeroot xinetd libdb2
sudo apt-get samba openvpn x-window-system-core
sudo apt-get dist-upgrade


Download the vmware-server.tar.gz and copy to the /tmp directory
Extract it tar -zxf vmware-server.tar.gz
Move to the vmware-server-distrib directory and run ./vmware-install.pl

This is all for getting the base server going.

New Project ... (PodPicker)

Added on by Ray Insalaco.
This is a PodCast aggregator that will auto-sync with an iPod. To the best of my knowledge there is nothing designed for Linux that works as smooth as iTunes. Which is the only application that is making me dual boot. Ad yes I know there are ways of doing this, but all the solutions that I have seen require several applications and way too much manual intervention.

See the project page for PodPicker ...

Ubuntu Dapper Drake 6.06

Added on by Ray Insalaco.
I have been using Dapper for two months now and I have to say that they have nailed this release. It has been stable from the word go and Ubuntu has added some really nice improvements, I like the new version of Gnome, power management has been improved and the networking has been much easier as well. I am going to be moving a production server to this build within the next couple of days, so we will see if the stability continues on the server, That will be running several things that the notebook is not and will also not be seeing the reboots that a notebook does as it is being transported.

Bad Idea, Happy Ending

Added on by Ray Insalaco.
I have been using Linux for almost two years now, however two weeks ago I became frustrated with some of the shortcomings of Linux. I formated my notebook and installed Windows XP on it. I develop software for several companies, so there are lots of tools and applications that need to be installed. After two days everything was installed and I was back in business. I took a total of three days of using Windows again to remember why I quit using it full time in the first place. It really does suck. Between to constant array of blue screens, lockups and other stupid problems. I always love it when you have two programs that just can not be installed on the same program. It didn't take long for me to be back on Linux. So I am happily back on Ubuntu Dapper Drake.

One of the first things I did after getting back on Ubuntu was to get the NetworkManager working. This is used for configuring wireless networks and works almost as good as the wireless ability in Windows. It also supports both WEP and WPA without any extra configuration. The steps to install NetworkManager are:

sudo apt-get install network-manager-gnome
sudo gtk-update-icon-cache -f /usr/share/icons/hicolor/
sudo cp /etc/network/interfaces /etc/network/interfaces.back


Edit the file interfaces so only the following lines are left:
# The loopback network interface
auto lo
iface lo inet loopback


Then a quick reboot and you should be ready to go. If you are using KDE then you can install network-manager-kde. If you do not edit the interfaces file then NetworkManager will not be able to control the nic cards.
sudo vi /etc

The New Computer, Finally ...

Added on by Ray Insalaco.
My new computer finally came in this week. It only took about two hours before it was being formated and Linux installed on it. I install Ubuntu Dapper Drake on it. so far I love the new computer, with the exception on the keyboard. The layout of the keys is very different that any other notebook that I have had, or used. I created a quick little shell script to configure my computer after doing an install. After installing the OS, I set the root password, switch to su and then run the script. At that point, it is a case of walk away and get something to eat.


#!/bin/bash
# System setup script.

# Update the software repositories ...

You may have to make some changes to fit your system. I am running a Pentium M, so I wand the 686 kernel image. If you are running a Athlon XP you would set the kernel version to k7, or 386. A quick google search should let you know which version will work for you.

Well that is all for now ...

ECLUG Meeting for April

Added on by Ray Insalaco.
Tonight was our April meeting. The first of the hour was spent discussing Apple and some of the exiting things that they are working on. I personally do not work with any Apple computers, but it was still pretty good to hear were they are going and talk about how it could effect the IT industry. It did not hurt that Apple had just released details about Boot Camp earlier today.

NFA has been using VMWare ESX to consolidate there servers for the last couple of years, so we spent time looking at what they are doing. I have looked at using ESX at work to consolidate some servers myself. That made this all the more interesting, getting to actually see ESX in action. They are running 14 virtual machines spread over 2 actual servers. I have read about the resource usage and how it works, but it was more impressive seeing running.

The next meeting we have someone giving a demo of XEN, and if time permits we will setup a box with XEN and add a virtual machine. We have not had a hands on meeting for some time so that should be fun.

For anyone interested the ECLUG, Eastern Connecticut Linux User Group, meets the first Wednesday of each month in Norwich, CT at NFA.

ECLUG Meeting for tonight.

We had our monthly LUG meeting tonight. The meeting had a different flow tonight, as most of the officers were out. It was an open floor for discussing different topics that members wanted information on. Based on tonight's meeting we are going to move forward on setting up the server for use at the meeting for demo's and testing new distros and packages. That should be fun. Well this is not much of a post, but I need to be up early in the morning.
