  2. DEBUG HINTS
  3. - Check the source is issuing multicast packets with TTL high enough
  4. to reach the recipients.
  5. - Check the multicast packets are not being dropped due to
  6. fragmentation problems.
  7. - The following command generates a 100-kbps multicast stream for
  8. channel 1.1.1.1,239.1.1.1 with TTL 10 and 1000-byte payload per UDP
  9. packet (to avoid fragmentation):
  10. nepim -b 1.1.1.1 -c 239.1.1.1 -T 10 -W 1000 -r 100k -a 1d
  11. - Remotely you can receive that stream by running:
  12. nepim -j 1.1.1.1+239.1.1.1@eth0
  13. (Remember of enabling both "ip pim ssm" and "ip igmp" under eth0.)
