Description Need Real Name 2002-10-01 17:13:26 EDT
I rebooted my RedHat 7.3 server.  It was having some kind of wacky file
descriptor insanity.  When it came back on-line I was unable to ssh in because
the /etc/nologin was still present.  I had to ssh in as root (only possible
because I had overlooked this security hole) and remove the file before I could
log in as a normal user.

Expected Results:

  I think the mature UNIXes deal with this problem by performing an "rm
/etc/nologin" somewhere in their init scripts.  RedHat should do this too. 
rc.sysinit is the likely candidate.

This was determined as not the way to do it back in 1999; I'm not sure I want to
change this behavior now.
Comment 2 Need Real Name 2002-11-12 10:51:24 EST
So, are you saying that when the reboot malfunctions somehow and the machine
boots with an /etc/nologin that the only resolution is physical access by
someone with the root password?

If this is the case, how do I prevent /etc/nologin from being created during the
reboot process?

The other UNIXes have this behavior (which has been in place for decades) correct. 

A reboot should delete the /etc/nologin file.

I'm happy to see that 8.5 years later, RHEL7 agreed with me. :)
