Shorewall Requires:
- A kernel that supports netfilter. I've tested with 2.4.2 -
2.4.20. With current releases of Shorewall, Traffic Shaping/Control requires
at least 2.4.18. Check here for kernel configuration
information. If you are looking for a firewall for use with
2.2 kernels, see the Seattle
Firewall site .
- iptables 1.2 or later but beware version 1.2.3 -- see the
Errata. WARNING:
The buggy iptables version 1.2.3 is included in RedHat
7.2 and you should upgrade to iptables 1.2.4 prior to installing Shorewall.
Version 1.2.4 is available from RedHat
and in the Shorewall Errata.
- Iproute ("ip" utility). The iproute package is included
with most distributions but may not be installed by default. The official
download site is ftp://ftp.inr.ac.ru/ip-routing.
- A Bourne shell or derivative such as bash or ash. This shell
must have correct support for variable expansion formats ${variable%pattern
}, ${variable%%pattern}, ${variable#pattern
} and ${variable##pattern}.
- Your shell must produce a sensible result when a number n (128 <=
n <= 255) is left shifted by 24 bits. You can check this at a shell prompt
by:
- echo $((128 << 24))
- The result must be either 2147483648 or -2147483648.
- The firewall monitoring display is greatly improved if you
have awk (gawk) installed.
