Very Computer

Just to be sure, I installed the latest Recommended Patches cluster for
2.6.
I then re-installed the anonymous ftp directory using the script that
comes with the man page for 'ftpd'. This didn't change the behavious of
'ls'.

Has anyone else seen this?

I'll post a copy of the reply I sent privately:

Hi,
 Thanks for the suggestion. I think that you may have come close to
hitting the nail on the head. From the commands I have run, I still can't
see the forest for the trees, but you might have an idea.

I'll show you the record of my tries, ending with the output of 'truss',
and then a directory listing of /home/ftp.

Sure enough, chroot doesn't want to work, as in:

#
# chroot ~ftp ~ftp/usr/bin/ls -l
chroot: No such file or directory
#
# chroot ~ftp /usr/bin/ls
ld.so.1: /usr/bin/ls: fatal: /dev/zero: open failed: No such device or
address
Killed
#
# cd ~ftp
# pwd
/home/ftp
# ls

I had this problem once in 1996. Sure wasn't obvious until I found it. ;)
