My favorite kind of combination.
Check out Chat Noir, a really game that is applicable to some problem within Graph Theory, I dare-say something associated with pursuit and evasion, though I am hesitant to use that label here.

Ubuntu 7.10 - Gutsy Gibbon (VPN running)
Back in linux, I follow the link and download the file. After unzipping the tar.bz2 file, I cd in and run ./vpn_install. Magic happens. Next, to start the thing. In the future, I hopefully don't have to do this, since it should be done automatically:
sudo /etc/init.d/vpnclient_init start
Ok, next, I need profiles. Before, when love was on the side of vpnc, I would have to enter the gateway info, and two passwords. This was doable, and ok. Now I need profiles. With a touch of chagrin, I realize that this probably the program that the help desk wanted me to run all along, though the tar file I downloaded was different. Going back to the RPI helpdesk site, I download the necessary .pcf files and put them in /etc/opt/cisco-vpnclient/Profiles/
The following command is then used:
sudo vpnclient connect RPI_External_VPN
Magic happens: user names and passwords are entered, information is exchanged. Sparkles and rainbows shoot out of my terminal. And suddenly..!
Negotiating security policies.
Securing communication channel.
Your VPN connection is secure.
To check, I try to connect to my server. No problems! Hooray! VPN now works!
Ugh. It's been fun, I think. I haven't checked RPI Wireless yet, but something tells me it will work (before it didn't). So overall, a productive and good use of time.
I -am- hungry. Maybe food is in order? That's a good idea. Food, and a hot shower.
Till next time...

Ubuntu 7.10 - Gutsy Gibbon (Fixing VPN)
Now in Windows, I test out my Cisco external VPN connection. After successfully being able to connect to my server (which is now behind the firewall -- another rant), I knew there wasn't anything wrong with External VPN. So one of two things must have happened.
By some hidden magic, External VPN no longer supports vpnc, or by some other hidden magic, vpnc changed somehow from Ubuntu 7.04, to 7.10, in an unproductive manner for me.
I head over the help-desk site and see the package that they have for linux. I shudder I -really- don't want to deal with their shit if I can get things working on my own. Back to ubuntu forums. Sure enough, other people seemed to be having a similar problem.
I now have the following instructions:
You can find the client here:
http://linux-support.hiwi.rz.uni-kon...1.0640.tar.bz2
Extract the file. Make sure, that you have installed the kernel headers and then run
sudo ./vpn_install
Link
h'okay, then, let's see what we get. Reboot into linux.

Ubuntu 7.10 - Gutsy Gibbon
So I developed a nasty head cold last night, and as of this morning, am still feeling pretty terrible. I think among the things necessary for a cure are food and fluids, neither of which I've had since my meager bowl of oatmeal last night.
Because I wasn't feeling well, I played on my DS, but eventually got bored. So I decided to upgrade my current system, which ran Ubuntu Fiesty 7.4 to Ubuntu Gutsy 7.10. Flipped open system upgrade, and told it to upgrade to 7.10.
I immediately began having doubts. Usually, when a new OS comes out, there are bugs here and there, and I winced remembering my wireless adventure dealing with my network stuff. Things were working perfectly now, after all.. why change things?
To test how well the upgrade will actually upgrade my system, rather than downgrade it, I authorized the go ahead.
The upgrade was relatively painless; it took about an hour to download the upgrades, and another hour to install all the updates, which was pretty reasonable, especially since I don't have the best of wireless connections here at the apartment. So, I restarted the system to see what it all looked like.
Things were ... mostly the same. Gaim had disappeared, since now Pidgin is exclusively supported. I added the Pidgin Icon to the panel, rearranged it some, and my panel looked as good as normal, save for this weird purple pigeon icon being where my simple, yet elegant yellow man icon used to be. Ah well, I'll get over it. The biggest change was that wireless was no longer working. At all.
SHIT, I thought. This could be for several reasons. 1.) Something different is going on that it was in Fiesty 2.) Something different is going on and it's going on worse because I TOLD ubuntu during the upgrade process to keep the modified blacklist file. SHIT, I thought, shit, shit, shit shit.. Worst of all, at that point in time, I had forgotten that the blacklist file was called "blacklist", so I didn't know where to look.
Rebooted into windows. Came to my blog, saw the notes I made last time about blacklisting goodness. Went back into linux. Located and went into this file:
/etc/modeprob.d/blacklist
After looking at the tail of the list, sure enough, my original changes were there. shit, I thought. So it' s no longer hostap that's the problem... wait, but what if hostap has control, and orinoco is the trouble? A few quick changes to the blacklist file yielded the tail of blacklist to look like this:
#buggy network-manager causes ornico to fight with it for wireless card
#blacklist hostap
#blacklist hostap_pci
blacklist hermes
blacklist p80211
blacklist prism2_pci
blacklist orinoco
blacklist orinoco_pci
With my fingers crossed, I restarted the system. Ubuntu came back up, and lo and behold! Wireless was working! Hooray! Scanning is re-enabled, and things looked like it was full of win. I was pleased to see that vpnc was part of the default install, and that all my previous settings were saved. Let's see if I can connect to the external VPN. A button click and two passwords yielded:
VPN Connect Failure
Could not start the VPN connection 'External VPN' due to a connection error.
The VPN login failed because the VPN program could not connect to the VPN server.
Shit, I thought. Not good. I checked configuration file. No problems seem to be there, since indeed, it was my previous settings. I was able to connect via external VPN no problem since I last checked, which was two days ago. Could something actually be wrong with External VPN connection at RPI? or is it VPNc? Let's check.
System reboot into Windows.

Some fun
For all of those who think that "Codex Carnivorous" may be experiencing a revival, surely you're imagining things...
