I SSH to a server from my laptop since some weeks ago. Today I want to SSH to the same server but from a different laptop and I can't make it work.
Both laptops run on Ubuntu 18 and I've copied the following files from the previous laptop to this new laptop:
/etc/hosts ~/.ssh/config ~/.ssh/known_hosts /etc/ssh/*
This is the output when I SSH with
OpenSSH_7.6p1 Ubuntu-4ubuntu0.3, OpenSSL 1.0.2n 7 Dec 2017 debug1: Reading configuration data /home/tomas/.ssh/config debug1: /home/tomas/.ssh/config line 2: Applying options for <server_name> debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 19: Applying options for * debug1: Connecting to <server_ddns_url> <server_ip> port <port_number>.
