Hello,
I have a suggestion for improving Red Hat linux (I've actually seen
this in OpenBSD): Red Hat Linux adds many pseudo-users (for example
named, squid, ident, rpc, rpcuser, etc.). It adds these pseudo-users
with /bin/false shell. I suggest to add the /sbin/nologin program to the
system, and use this as the default shell of the pseudo-users. Then you
can make /sbin/nologin to complain loudly when it is executed. User can
thus spot possible break-in attempts.
What do you think about it?
