I have noticed that after upgrading my laptop (not sure if this is the reason) to 18.04 Ubuntu, I have not been able to ssh to an institute server although I'm able to on the same internet network from a desktop computer.
When "ssh -v" is applied the following is the result before timing out:
OpenSSH_7.6p1 Ubuntu-4ubuntu0.1, OpenSSL 1.0.2n 7 Dec 2017 debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 19: Applying options for * debug1: Connecting to xxx.xxxxx.xxx.edu [128.118.xxx.xxx] port 22.
I have tried deleting the known_hosts file, as it was one of the suggestions on the internet. However, it did not resolve this issue. Any tips that might help fix the problem are welcome. Thanks!
