Suse 9.2 / Multicast


Hi all,

My problem is the following...

Code:
dhcp246:/home/hasv # ifconfig
eth0      Link encap:Ethernet  HWaddr 00:02:3F:BD:17:58
          inet addr:10.0.100.246  Bcast:10.0.255.255  Mask:255.255.0.0
          inet6 addr: fe80::202:3fff:febd:1758/64 Scope:Link
          UP BROADCAST NOTRAILERS RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:23417 errors:0 dropped:0 overruns:0 frame:0
          TX packets:9460 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:7379161 (7.0 Mb)  TX bytes:1501695 (1.4 Mb)
          Interrupt:11
 
lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:293 errors:0 dropped:0 overruns:0 frame:0
          TX packets:293 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:35540 (34.7 Kb)  TX bytes:35540 (34.7 Kb)

eth0 has multicast available: but if another computer on the same network tries issuing "ping 224.0.0.1" it won't list my ip. Although i can receive those packets


Code:
dhcp246:/home/hasv # tcpdump -i eth0 ip multicast
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes
18:20:59.389493 IP orange.isrnet > ALL-SYSTEMS.MCAST.NET: icmp 64: echo request seq 1
18:21:00.390246 IP orange.isrnet > ALL-SYSTEMS.MCAST.NET: icmp 64: echo request seq 2
18:21:01.392081 IP orange.isrnet > ALL-SYSTEMS.MCAST.NET: icmp 64: echo request seq 3


Does anyone know why is this happening? If so how to solve it? I want my computer to respond to the ping command.

Any help would be appreciated.
