ssh config is working from home, but not working from another directory

问题

I could solve my problem, but I'm pretty curious why it isn't working the way it should be.

The problem:
In ~/.ssh/config there is an entry:

Host git
HostName git.myserver.com
User gitolite
Identityfile gitolite

After that in my home directory when I run: ssh git it returns this text (which is a normal thing):

PTY allocation request failed on channel 0

hello myname, this is gitolite@myserver.com running gitolite3 v3.4-3-g797a81f on git 1.7.2.5

 R W    myrepo1
 R W    myrepo2
 R W    .
 R W    .
 R W    .
Connection to git.myserver.com closed.

But when I'm running ssh git from my /opt/poky directory, it cannot authenticate me with my file... or I don't know what's the problem, but the result is:

gitolite@myserver.com's password:

Most interesting is when I'm changing my .git/config's url variable from git:poky to gitolite@git.myserver.com:poky then everything works fine.

It seems more an ssh issue than a gitolite.

Could it be some environment variable?

回答1:

Your config file should contain, to be sure, the full path of your private/public key:

Identityfile /path/to/gitolite

Beside that, make sure $HOME is the same in both cases, and that you are running those commands with the same user id, to rule out any right access.

That means your public/private key (named ~/.ssh/gitolite(.pub)) is duplicated as ~/.ssh/id_rsa(.pub), which is the default name for those keys, as searched by ssh.
