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 email@example.com -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 firstname.lastname@example.org tip /dev/tts/0 ssh -t email@example.com 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)
4. More Instructions
Log into kvm.hcoop.net with the secret password.
You can then click on the screen to launch the a Java applet, or you can connect with a vnc client natively if the applet is too slow on your system.
The screen will probably be blanked; press a key to refresh the screen.
Channel 1 is Deleuze, channel 3 is mire. To switch between screens use the sequence Scrl Lock, Scrl Lock, followed by the Up or Down key.
You cannot press the keyboard Scroll Lock button. Instead, click on the [S] button twice. Before you click, mouse over the [S] and ensure that it is highlighted as below.
A caption with the channel number should appear in the upper left corner of the screen as pictured below. Now press Up or Down to change the active channel.
