In the openssh Red Hat package, I noticed that the
ssh-agent executable has the SGID permission set:
$ ls -l /usr/bin/ssh-agent -rwxr-sr-x 1 root nobody 113648 Nov 24 2010 /usr/bin/ssh-agent
Why would the openssh developers want
ssh-agent to run with the
nobody group? Or maybe I am misunderstanding what SGID does?
