I have a gitolite server and an ubuntu pc.
I have connected my ubuntu pc via ssh with the gitolite server and all is good. Although, I did this withought knowning how ssh actually works.
If I change the hostname,the username,the home directory for the user I want to rename, on my ubuntu pc will it affect my git?
Change you host name does not affect git, but username or homedir do.
SSH connection uses SSH-key files located in your <home-directory>/.ssh/ folder. So, if you change the user - be sure your new home folder contains folder .ssh/ with original files. I think you can backup the folder (.ssh) before you create/rename user and his home folder.
In case you want create a new SSH-key files - use ssh-keygen utility. It requires to add content of ssh public key to your user settings in gitolite server
