Trouble with tcpdump, iftop and p0f
Hello,
I use debian/squeeze on some UltraSPARC workstations (U1, U2, U60,
U420). For some bad reasons (a netdev watchdog error), all sparc run
with a 2.6.28.x kernel. I have seen that tcpdump, iftop and p0f do not
work anymore. For example, tcpdump returns nothing but number of packets :
Root rayleigh:[~] > tcpdump -i eth0
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes
^C
0 packets captured
14 packets received by filter
0 packets dropped by kernel
Root rayleigh:[~] >
iftop always returns 0. /proc/net/dev seems to be good :
Root rayleigh:[/proc/net] > cat dev

Have you seen this bug ? Is there an issue ?
