Hifs: Handy Information For Sysadmins 1.4, November 1997
To learn more about hifs: see the manpage, `hifs.1'. For the copying
policy, see the file COPYING (hifs is GPL software).
Compilation hints:
In the file INSTALL there are generic install instructions. However,
the following instructions should build and install hifs in almost all
circumstances. If you build the setuid version of hifs, you can su to root
from within hifs. You do this by giving --enable-su-to-root as an argument
to configure.
~/hifs> mkdir compile; cd compile
~/hifs> ../configure --help
~/hifs> ../configure [--enable-su-to-root]
~/hifs> make; make install
Setuid version:
If hifs is compiled with the su-to-root option, hifs will be a setuid
root program and therefore inherently insecure. I put a lot of effort in
creating secure code, but I can't make any guarantees about security. Having
said this, this is what hifs does to prevent abuse:
o Drop priviliges right away.
o Take care that buffer overruns don't occur.
o Verbose syslog() reporting.
Latest version:
The latest version of hifs is available via anonymous ftp at
skynet.stack.nl in /pub/linux/hifs.
Author:
Linux Hifs is created by Geert Jansen (geertj@stack.nl). It is inspired
by the original FreeBSD version created by Sven Berkvens (sven@stack.nl).
