Subject: Libraries for anonymous FTP

Hello,

we've about 200 anonymous users on our AIX 4.3.2 server running WU-FTPD 2.4
VR 17 and have
following problem. For every new user we have to copy libc.a, libcurses.a to
the user's home directory
which makes about 6megs files pro user. That does make 1,2Gb for the 200
users. Is there a another
method to have those files without copying them each time to the user's home
directory?

Thanks a lot for your help,

Lauer,

So long as they are all on the same file system, you can create hard links
to a copy of the libc.a..... from each user account.  It's probably not
wise to link them to the /usr/lib copies.  Note - Symbolic links do not
work across chrooted areas.

I have a small script one of my people developed which creates chrooted
areas for a solaris system.  I can forward you a copy if desired.

I'd move the chroot to a point common to all users then use the
'restricted-uid' feature on VR17 to keep them apart.  That way, one copy
of the library, without links, would serve for all users.
