Re: [Wlug] WPI Exchange Help

by Eric Stein

At one point, the UNIX/Exchange battle that goes on between the two servers was so screwed up that all my email was showing up as literal forwards from me to me in my UNIX inbox. I raged at the helpdesk until they accepted that I did not now, nor did I ever want, to even have an exchange account. It took some fighting but I got them to delete my exchange account completely, and my UNIX mail has worked fine ever since.

Re: [Wlug] WPI Exchange Help

by Kurt Snieckus

On the WPI mail system mail first goes to the unix mail servers, and then gets forwarded to exchange. If you want you can keep the mail from being forwarded to exchange by changing the forwarding settings here: http://www.wpi.edu/Academics/CCC/Services/mailforward.html I forget exactly what I did, but it didn't work quite right, beacuse mail sent from other user's exchange accounts went to the exchange account instead of staying in the unix account. But if you e-mail the Helpdesk they can fix it for you. This then lets you use imap.wpi.edu, pop.wpi.edu, and webmail.wpi.edu/squirrelmail (And i think you can just login to ccc.wpi.eduand type pine and read your mail as well) If you'd like in-person help the Free Software Association tries to have meetings at 6pm on Tuesdays in the lounge on the 3rd floor of Fuller.

Have you tried using the 'nxserver' instead? I've been playing with it a bit, and it's not blindingly fast at points, but it does seem to support better OpenGL over the WAN/LAN than X does at time, esp VNC. You might try turning off authentication completely as a test and see if you can make it work then. Try 'xhost +' and see if that works for you. John

gl over ssh

by bkn＠ithryn.net

Hi all, I've run into snag with using ssh x-forwarding and GL. I'm trying to run a program which uses GL remotely. The program runs and the GUI pops up with sliders and such visible, but the GL part of the gui is not displaying. everything else with the program is functional. When i start the program from the prompt i did notice the following error, libGL error: XF86DRIAuthConnection failed libGL error: reverting to (slow) indirect rendering and on the side that displays the program i see the following error in the xorg.log file (each line represents each attempt at running the program), failed to authenticate 8 failed to authenticate 9 I've google'd around and haven't much useful information. i do have write permissions to /dev/dri. Also local GL programs display just fine, this only happens with ssh forwarding (i've tried ssh -X and ssh -Y). Both machines are ubuntu, the display machine is ubuntu 8.10 and the other is 8.04. They both use the stock xorg.conf file, which is pretty minimal, i'm guessing that's because xorg tried to determine everything at runtime. If anyone has any hints or suggestions, let me know, thanks. Thanks, -- brad

The Care and Feeding of a dell power edge 2650

The student organization i belong to has recently been entrusted with a retired dell power edge 2650 rack mount server. Me and another club member are going to be in charge of setting up and maintaining the server. I'm pretty sure there is a lot of information i'm simply not aware of and i was wondering if anyone with IT experience would be willing to give me a few pointers. My current plan is to install a minimal system (prefferably debian based) install the services i need (LAMP) and then harden the box with a set of restrictive iptables rules and keep up to date with security updates.

The main problem with sticking with it is there isn't any package management, so you have to keep abreast of security / feature updates and make sure everything plays nicely with everything else. Might I inquire why you want to put yourself through that? It's a fun experience but the system gets outdated very fast. If you're tried of binary distros I would suggest Gentoo.
