My Ubuntu keeps sending out IGMP Query requests for following IPs: 239.255.255.255.253, 224.1.1.7 and 234.55.66.77. I figured this out from Wireshark. As per IGMP spec, I believe query requests are sent only by routers. So,
- Why is my machine sending these packets (i.e. behaving like a router)?
- Which process sends these packets? I checked there is no mrouted or XORP or Quagga installed.

I would suggest you monitor the
netstat
to find out the 'culprit':There are some things you can check:
IGMP snooping feature is enabled:
corosync
in multicast mode
