| 3 | DEBUG HINTS |
| 4 | |
| 5 | - Check the source is issuing multicast packets with TTL high enough |
| 6 | to reach the recipients. |
| 7 | |
| 8 | - Check the multicast packets are not being dropped due to |
| 9 | fragmentation problems. |
| 10 | |
| 11 | - The following command generates a 100-kbps multicast stream for |
| 12 | channel 1.1.1.1,239.1.1.1 with TTL 10 and 1000-byte payload per UDP |
| 13 | packet (to avoid fragmentation): |
| 14 | |
| 15 | nepim -b 1.1.1.1 -c 239.1.1.1 -T 10 -W 1000 -r 100k -a 1d |
| 16 | |
| 17 | - Remotely you can receive that stream by running: |
| 18 | |
| 19 | nepim -j 1.1.1.1+239.1.1.1@eth0 |
| 20 | (Remember of enabling both "ip pim ssm" and "ip igmp" under eth0.) |
