Struggling with ssh working locally, agent forwarding not working correctly after moving your ssh keys around?

Firstly make sure that your permissions are correct on your SSH keys

My config looks like this:
-rw-r--r--   1 jsmale  staff   356 18 Sep 17:39 config
-rw-------@  1 jsmale  staff  1675 12 Jul 00:54 id_rsa
-rw-------@  1 jsmale  staff   400 12 Jul 00:54 id_rsa.pub

If they are wrong:
chmod 600 id_rsa id_rsa.pub
chmod 644 config

Then make sure that your ssh key is added correctly:
ssh-add -l

My response:
› ssh-add -l                 
2048 25:89:39:cf:85:b6:43:81:f7:e3:47:d0:63:84:2b:7c /Users/jsmale/.ssh/id_rsa (RSA)

If it isn't, then:
ssh-add
