I'm trying to ssh into a remote server using the format:
user@ip -i ~/.ssh/path/to/key
and I get the following error:
/etc/ssh/ssh_config: line 55: Bad configuration option: gssapikeyexchange /etc/ssh/ssh_config: line 56: Bad configuration option: gssapitrustdns /etc/ssh/ssh_config: terminating, 2 bad configuration options
Connecting to a server without an SSH key doesn't work either.
