tlug: ftpd segv's with PAM

["Andrew S. Howell" <andy@example.com>]

Hello,

	I spent more time than I'd care to admit, getting ftpd to work
with RH 5.0.

Summary:

	comment out:

auth       required     /lib/security/pam_listfile.so item=user
sense=deny file=/etc/ftpusers onerr=succeed

in /etc/pam.d/ftp. ftpd core dumps in pam_listfile.so.

The gory details:

What I should have done was attact the config files right away. But
no, I noticed that ftpd was died with a SEGV, so silly me had to try
and figure out why. (:

First problem, how to get it to generate a core dump? It turns out the
inetd with ulimit for core dumps set to 0, ie no core dumps are
made. After:

	killing inetd
	ulimit -c unlimited
	inetd

ftpd made a core file in the directory where I started inetd from.

I haven't figured out why it cores yet. The file /etc/ftpusers looks
fine. I tried downloading the latest PAM from 

ftp://ftp.kernel.org/pub/linux/libs/pam/pre

and installed only the pam_listfile.so, but it complains about dlopen
not being able to resolve the symbol lstat. Not sure why. Thats a
battle for another day.

Hope this helps someone...

Andy
