Description Henri Schlereth 2001-01-19 11:33:30 UTC
The version of ipchains as supplied on the beta2 disc's is no longer compatible with the 2.4 kernel.
ipchains is now a loadable module in the kernel. During an upgrade from RH70 --> beta2 it will however still
upgrade ipchains. This becomes a security issue because ipchains will no longer work unless loaded as 
a module. The ipchains init scripts do not address this nor is there an apparent ipchains --> netfilter
conversion process in place. The net result is that if you upgrade a firewall you end up unprotected.

Even if the upgrade were to remove ipchains unless there is a conversion script you again would wind
up uprotected.

Last year I had 239 attempts that were blocked by a combination of ipchains, portsentry, and tcp_wrappers. As it
stands I would not dare put this on my firewall if this were the finished product.

Comment 1 Henri Schlereth 2001-01-19 13:12:26 UTC
Further research shows that ipchains 1.3.10-1 will work after you insmod the
ipchains.o.
That still leaves the issue of why isnt this automated?  If this had been a real
firewall I 
would have had an unprotected network until I figured out that it requires/needs
the module.
