Citrix SSL error 61 You have not chosen to trust…

linicaclient Well to be more precise,  the exact error was:
You have not chosen to trust "Equifax Secure Global eBusiness CA-1", the issuer of the server’s security certificate (SSL error 61).
More and more people are dipping their toes in Linux and Apple computing these days only to find that they cannot connect to their Citrix environment using Firefox for example. Here’s how to fix that..

Upgrading Debian Sarge Kernel Image

debian.jpg
Yep, decided to pay attention to the Debian Security Advisory 1103 :

DSA-1103-1 kernel-source-2.6.8 — several vulnerabilities
Well I tried doing my usual apt-get upgrade, but the update didn’t show up. I must have had a hole in my head or something…I asked around on IRC what the correct syntax was for installing this update because I forgot:
apt-get install kernel-image-2.6.8-3-386 did the trick.

After that I rebooted my Virtual Machine, I saw that my virtual network adapter was no longer working..!
That problem lies in the fact that I compiled my VMWare Tools with the kernel-headers from before the update. Now that I booted into the new kernel: no more VMWare-Tools….so now what ?!
First, I reverted my snapshot 🙂
Now, let’s install the kernel-headers that go with the new kernel:
apt-get install kernel-headers-2.6.8-3-386
after that installed the update again

I rebooted, of course no more network because of what I described above.
Now, login through the console and run the following command:
./usr/bin/vmware-config-tools.pl
This command will recompile your VMWare Tools and VMX-Net adapter !

One thing is still bugging me, when I boot my machine, I still see the “older” kernel image listed in my Grub boot loader. I don’t know if I can easily remove it. If Debian releases a couple more Kernel patches like this, I’ll have 10 kernel options to choose from when booting (every kernel image also has a “safe” boot mode)
If someone has a clue on what best practice for this situation, please send me a mail…just put info and a @ infront of my domain and I’ll be waiting 😉

subprocess post-installation script returned error exit status 255

Uhhhh…that’s what I thought when I tried to patch my mysql package with security updates.
I did a apt-get upgrade as usual and this was the full error I received:
Setting up mysql-client (4.0.24-10sarge2) …
Setting up mysql-server (4.0.24-10sarge2) …
Stopping MySQL database server:
mysqld.dpkg: error processing mysql-server (–configure): subprocess post-installation script returned error exit status 255
Starting MySQL database server: mysqld Errors were encountered while processing: mysql-server E: Sub-process /usr/bin/dpkg returned an error code (1)
mailserver:~# .Checking for crashed MySQL tables in the background.
Now thank the lords of Kobol for VMWare Snapshot technology …I’m running my debian mailserver under VMWare GSX server 🙂 I reverted to my snapshot and tried again…I did two things different (stupid I know but I was in a hurry!)
I closed my mailclient still connected to my mailserver (using mysql as backend) I also did the apt-get upgrade command from the console instead of using SSH. I don’t know why but did not show up this time so all is well for now…

The following packages have been kept back

I run a Debian Mailserver with Postfix..(the best MTA available in my opinion!) within my Debian box, I use the apt-get upgrade functions for security updates. for a little while I kept seeing this message when upgrading:
The following packages have been kept back
Well Google is your best friend and helped find this article which explains why this happens:
Some upgrades show packages being kept back
In short: to fix it you type the command: apt-get dist-upgrade
