SSH gets stuck

[Khizar Amin]

Hi, my experiment kamin07-104551 with 1 node only under the NGN-Wireless project was running fine until yesterday but now I am unable to SSH into the node. The SSH command gets stuck. Console log does not show anything out of the ordinary and Top processes option shows sufficient free memory and my scripts appear to be working fine (top processes are cycling between the chromium and Tor, which is expected). I have tried clearing known SSH hosts but to no avail.

Hi. Can you please tell us the IP address that you are ssh’ing from?

Thanks

Hi, I am trying to access it using my university wifi (LUMS, Pakistan) and the IP address would either be 58.27.202.37 or 221.120.220.11

Hey, I just tried to ssh again and got this error "kex_exchange_identification: Connection closed by remote host. Connection closed by 155.98.38.90 port 22"

Hi. Different error. Can you do an ssh -v please and send us the logs.

Thanks

Hi, just tried SSHing again and it did work. Will report back with logs if the problem appears again.

Thanks for your time!
