Re: CentOS 5.4 + xinetd + sshd + SELinux issues

Hi all,
I have a problem trying to run sshd via xinetd on a CentOS 5.4 system
(I want to slap a tcpwrappers-style wrapper before sshd, so I need it
that way).
In permissive mode I can log in/out with the following failures reported
by audit2allow:
allow amanda_t consoletype_exec_t:file { execute execute_no_trans };
allow amanda_t devpts_t:chr_file { write ioctl };
allow amanda_t hostname_exec_t:file { execute execute_no_trans };
allow amanda_t shell_exec_t:file entrypoint;
I don't even have amanda installed, so the context is clearly bogus.
After a chat on #fedora-selinux it seems that sshd cannot find its
default context, so falls back to the first available one, which happens
to be something:something:amanda_t (the list is read from /selinux/user).
This operation is performed by sshd itself (as verified by strace).
I don't need Fort Knox type security but I'd like to use SELinux to
tighten down other parts of the system, so I'd really like to use the
enforcing mode.
Any hints? A good TFM to R will hopefully do.
Best regards,
Grzegorz Nosek

This looks like you have a very screwed up system.
What domain is sshd running with?
ps -eZ | grep sshd
You could try a relabel
touch /.autorelabel; reboot
Which should get all the processes running in the correct domain.
