Hi Felix

FYI

Tried your traffic.c.

Just for clarification, it seems that for your program to work, one
must excute a program like dvbstream. Is that intended ?

Another problem that I have is that I can only get your
program to work sometimes. 5 out or 6 times it just reads
between 50-1800 packets and then waits in a read().

Sometimes it works and produce something like

bash-2.05a$ ./traffic
0135  2715 p/s   498 kb/s  4084 kbit
0136   136 p/s    24 kb/s   205 kbit
2000  2852 p/s   523 kb/s  4289 kbit
0135  2256 p/s   414 kb/s  3393 kbit
0136   140 p/s    25 kb/s   211 kbit
2000  2397 p/s   440 kb/s  3605 kbit
0135  1700 p/s   312 kb/s  2558 kbit
0136   111 p/s    20 kb/s   167 kbit
2000  1812 p/s   332 kb/s  2725 kbit
0135  1056 p/s   193 kb/s  1589 kbit
0136   118 p/s    21 kb/s   178 kbit
2000  1175 p/s   215 kb/s  1767 kbit

but mostly it ends up waiting.
