Firewall and beacon
hello
I used to play with beacon 0.8.X and I really appreciate that you invest
in the developement of this beautiful tool !
So I upgraded to 1.1, howerver I cannot figure out how to set my
localhost firewall to permit either my own central server and client
beacon clients to pass through correctly ( I mean fine tune the
firewall) :-(
I work on a fedora core 2 system (Thanks for the RPMS !) -> so firewall
is netfilter/iptables.
I may also contribute myself to the project by writing a doc on the
fedora installation of a beacon client and server . It's available here:
http://www.int-evry.fr/mci/user/procacci/Doc/Beacon/beacon.html
In this doc I mention the FAQ/info provided by nlanr about firewall
configuration in my section 1.5
http://www.int-evry.fr/mci/user/procacci/Doc/Beacon/beacon.html#htoc9
Although theses settings works by restarting iptables while beacon
client&server are already running, the firewall needs to be stoped at
beacon client&server startup for the matrix to appear. (get initialized)
clearly I need to stop the iptables firewall on both client&server ,
then start them after matrix initialization, and it works. But if I
start the firewall first, the matrix (central loss for exemple) keeps
beeing empty :-(
I suppose I miss to allow in my iptable firewall the initial join in the
multicast group maybe ? or something else ?
as anyone configured correctly iptables to allow beacon client&server to
communicate ?
Thanks a lot.
PS: I'll correct my doc if I finally find out how to do it
PS again: I played with more sofisticated iptables rules like the one
below , but no way :-( , should I continue with these kind of multicast
rules ?
-A RH-Firewall-1-INPUT -m pkttype --pkt-type multicast -d 233.157.159.11
-j ACCEPT
