centos - Wrong gitosis config. I'm locked out the server




I made a stupid mistake. I have a small vhosted CentOS server and I was configuring git+gitosis when i think I ran the gitosis ssh key init on my own user in addition to the git user. I didn't realize it at the time but now when i try to ssh to the server with my user i get:



TY allocation request failed on channel 0
ERROR:gitosis.serve.main:Need SSH_ORIGINAL_COMMAND in environment.
Connection to [servernamehere] closed.


Any idea how I can login to the server again? Unfortunately i have disabled ssh root login.
Thanks!

Sorry Cristian no easy answer to this, your user can only interact with git.
