Description Sylvain Arth 2011-07-20 07:18:11 UTC
SELinux is preventing /usr/bin/ssh-agent from read, open access on the fichier /usr/bin/ssh-agent.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that ssh-agent should be allowed read open access on the ssh-agent file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep ssh-agent /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

What were you doing when this happened?

> What were you doing when this happened?
I can't figure actually
I only thought that too many selinux warnings (switched on permissive mode) were happening (most of them triggered by system's daemon or whatever), some looking like silly (bash reading .bas_history for instance) 
Hope this helps

Comment 3 Daniel Walsh 2011-07-20 21:55:34 UTC
This looks like the gkeyringd is trying to execute ssh-agent?  Has this changed?
