- gateway computer flaci@cpu-li20-sp01, accessible from mcclogin, facet-srv*, or thinsrv01
- digitizer computer luxelab@192.168.0.2 (in FKG20-24), accessible only from cpu-li20-sp01 (in FKG20-01)
- ssh flaci@cpu-li-sp01
- ssh luxelab@192.168.0.2
Setup the Tunnel between luxelab and facet-srv20
An example configuration file for the permanent tunnel is here: ssh-config-file
It also includes an example of a proxy jump. This can be applied the same way to go directly into facet-control.
Setup the Tunnel between luxelab and facet-srv20
- set up the SSH tunnel between the luxelab computer and the facet-srv20 we use the following command:
- [fphysics@facet-srv20 ~/ivoschul ]$ ssh -F .ssh/config -N -f luxelab
- -F defines the config file which is not at the default location, it defines
- the users, key-pair, IPs, and proxyjump
- RemoteForward 62882 localhost:62882
- RemoteForward 62883 localhost:62883
- -N makes the session non-interactive
- -f puts the session in the background
- to kill the session we can use the following:
[fphysics@facet-srv20 ~/ivoschul ]$ ps aux | grep 'ssh -F .ssh/config'
- this will output three processes, one is the grep command and two are the ssh connections to the gate and to the luxelab
- get the process ID of the connection to the gate and kill it with [fphysics@facet-srv20 ~/ivoschul ]$ kill processID
