1. IP KVM Tunneling

To use a VNC through a tunnel, one of the following commands must be issued More information needed...

 /usr/local/bin/stunnel -f -c -d 5900 -r kvm.hcoop.net:15900


 ssh admin@kvm.hcoop.net -L 5900:kvm.hcoop.net:5900

Then use your favorite VNC client to connect to localhost:5900. The KVM password has been distributed to admins; if you don't know it and think that you should, please contact them.

Once connected, you will be "looking through" an IP KVM which is connected to a KVM Switch (these are different devices!). By pressing scroll lock twice and then the up or down arrow (ie SCRL SCRL UP or SCRL SCRL DOWN) you can switch between the various machines connected to the KVM Switch. Currently there are two: deleuze and mire.

2. Serial Port

To access the serial port, use one of the following:

 ssh -t admin@kvm.hcoop.net tip /dev/tts/0
 ssh -t admin@kvm.hcoop.net tip /dev/tts/1

One command corresponds to each of the two serial port connectors on the KVM (we're not sure which is which). After executing the command above, your ssh session will give you a console on the chosen serial port (which is probably connected to the remote power-cycling machinery of one of the servers)
