anon-ftp problem

Post by Jeremy P. Campbel » Fri, 18 Dec 1998 04:00:00



I'm running RH 5.2 on an X86 box.

I'm having some problems with my anon-ftp service.  Specifically,
symbolic links are not followed for anon users.  Can anyone give me a
pointer on where to look for these settings?

This is probably because anonymous users are chrooted to the /home/ftp
directory and there is no way to chroot them and at the same time access
files outside of the root directory. A symlink within /home/ftp should
still work though.

Dont think so, unless the sombolic link is a relative link that stays
within the chrooted directory tree.

If it did work it would be a too easy way to break out of the chroot tree.
Normal (hard) links would work, but you would not be able to link to
a file outside the chrooted tree, as it is not possible to look up
the inode number of the target of that link while  trapped inside the
chrooted directory tree.
