Expected Result

Please check this link, it has more details Sign in · GitLab
Thanks it helped but now when I do this on my personal computer
sudo vim .ssh/config
and edit as
Host ygg
HostName login1.yggdrasil.hpc.unige.ch
User khansh
Host cpu001
HostName cpu001
User khansh
ProxyJump ygg
LocalForward 1234 localhost:1234
then ssh ygg
and then in a new terminal do ssh cpu001 it asks for a password for the cpu001.
You shouldn’t connect to ygg
but directly to cpu001
. This will use the ProxyJump
feature.
even tried that but still the same option comes up that give password for cpu001.
This time I had ssh cpu001 only.
Did you tried to type your password?
Yes it asks for password and my normal password works on that one. then it asks for khansh@cpu001’s password
Hi,
I can confirm that this isn’t working. The reason is that the authentication from login node to compute node isn’t done using normal authentication but using HostbasedAuthentication.
A working solution is
root@CL-hqhk4m2:~# ssh -t sagon@login2.baobab.hpc.unige.ch ssh cpu001

(baobab)-[sagon@cpu001 ~]$
Be sure to have a working session on the compute node first.
