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.
