Updating multple iptables on servers

Updating multple iptables on servers

[Thomas Kristensen]

Is it possible to update iptables from a central server. I got 25 servers
using the same firewall and i need something to update them all from a
central server. 
 
Any ideas?

Strange . . . I thought I saw this identical post a few days ago!

Although it is still a few months away from release, ISCS
(http://iscs.sourceforge.net) will help you do this.  It will also
manage any VPN and router configurations and, eventually, even the layer
two configuration.  It will do this just as easily if every firewall is
different - the work is the same - describe the environment and ISCS
automatically creates and distributes the list of rules to create that
environment.  I wish I could tell you it's here and ready for use but
it's still in very active development.  We're working on the last of the
iptables modules as I write.

fwbuilder (http://www.fwbuilder.org) is quite a good product more along
the lines of traditional firewall GUI's and is available now.

So did I.

Chris Brenton's answer looked promising:

Let us know if it meets your needs, or if problems remain.

Fanout is your friend:
http://www.stearns.org/fanout/

To quote the docs: "This tool will run commands on multiple machines at
the same time via ssh."

Bill has a number of excellent Linux tools up on his site, this being
one of them.

HTH,
Chris

Rsync or scp, then iptables-restore?
