I hate viewing logs in terminal with nano - it's just extremely inconvenient. There is an easy way to browse through a remote server's files if you have SSH access to the server in a GUI way using KDE's file manager Dolphin:
ctrl + L - to type the location manually, then:
fish - istead of ssh to connect to the server;
user_name - the user on the server, e.g. root;
xxx.xxx.xx.xxx - the server's IP address;
/directory - the directory you want to connect to; if you don't specify the directory, you'll just connect to the user's folder (root - if you connect as root) after which you'll be able to navigate further.
