[Devil-Linux-discuss] Antw: Multicast Routing does not work - new status

[Alexander R. <Ale...@ar...>]

hello everybody!

after searching the net the whole day yesterday I know a bit more about =
devil-linux and multicasting. so the kernel supports multicast routing by =
having the flags CONFIG_IP_MULTICAST and CONFIG_IP_MROUTE set. And I =
played around with the quagga zebra demon, butt this didn't help me.=20

I found out that the file "/proc/sys/net/ipv4/conf/eth0/mc_forwarding" is =
set to "0", but I can't change this value to "1", because this file is =
"r--r--r--". Trying to change the value with sysctl doesn't work either, =
even not on a reboot with the wanted changes written in "/etc/sysctl.conf".=
 Could this be a hardware problem (wrong NICs)?

so, any suggestions from your side?

Greetings,
Alexander Roos

Betreff:	[Devil-Linux-discuss] Multicast Routing does not work

Hello everybody!

I installed a Devil-Linux router (V. 1.2.9) in our Network an need=20
multicast-routing to run for our Novell-Clients. I googled the net for=20
solutions and found a hint to add a static route for the multicast-net=20
on the interface on which the novell-server resides.=20
(http://www.informatikserver.at/index.php?option=3Dcom_content&task=3Dview&=
id=3D10074&Itemid=3D99999999).=20


But this did not work. On the router I can ping the multicast address=20
239.255.255.253 to reach the Novell Servers, on a client that resides =
in=20
another ip-segment than the server I can't ping. Tcpdump shows nothing=20
on the serverside interface. I'm wondering if the DL kernel supports=20
multicast routing and if not how I can compile a new kernel with=20
multicast routing support.

Additionally I found that for the Service Location Protocol (SLP) which=20
is used by the Novell client to look up the Novell servers "pim" is=20
needed. There's something like pimd for linux, is it included in DL? If=20
not, how can I include it? Or is obsolete, if the kernel supports=20
multicast routing?

Thanks in advance,
Alexander Roos
