From donghanw at cs.cmu.edu Wed May 9 15:37:07 2012 From: donghanw at cs.cmu.edu (Donghan (Jarod) Wang) Date: Wed, 9 May 2012 15:37:07 -0400 Subject: [auton-users] Using VNC with SSH Message-ID: Hello lab, This post is intended for VNC users. If you ever use vncserver and/or vncviewer, you are a VNC user. Suppose you want to open a VNC connection to snoopy; the following two steps offers a secure and convenient way. Step 1: *ssh -L 5902:localhost:5901 snoopy* and any references to display :2 on your local machine would actually connect to display :1 on snoopy. Recall that VNC normally uses port 59xx, where xx is the display number of the server. Make sure that the local port, 5902 in this case, is _not_ being used. After that, you could run: Step 2: *vncviewer localhost:2* instead of running a vncviewer: vncviewer snoopy:1 That's it. This tip works on LInux and cygwin on windows. P.S. If you need to find out display port on snoopy, 5901 in this case, one way is to run ps aux | grep -i vnc and look for the number after -rfbport. -Jarod -- Donghan (Jarod) Wang Research Programmer Robotics Institute Carnegie Mellon University 5000 Forbes Avenue Pittsburgh, PA 15213 Email: donghanw at cs.cmu.edu Tel: +1 412 268 1238 -------------- next part -------------- An HTML attachment was scrubbed...

Any processes or sessions on that machine were killed. Please check your jobs. To ensure the system stability, I'm in the process of investigating and implementing a way, OOM (Out Of Memory) killer, to handle memory overcommit. OOM basically starts killing the greediest memory hog process, when the kernel runs out of memory. You may want to reserve for a host if significant cpu/memory consumption is expected.
