Hello,
I have build a 2.6.28.7 kernel on sparc64 (libc6 2.9). On all my
sparc64 (U60 with 3Com and HME NIC's, U1, U420 with HME), tcpdump
doesn't return any information (but it can count packets !) :
Root rayleigh:[~] > tcpdump -i eth1
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth1, link-type EN10MB (Ethernet), capture size 96 bytes
^C
0 packets captured
635 packets received by filter
0 packets dropped by kernel

With the same configuration (kernel and libc), I cannot reproduce this
bug on i386 or amd64. With 2.6.27/sparc64, tcpdump and others worked fine.
Problem : all programs that try to catch packets in promiscuous mode do
not work anymore. Is there any issue ?
Regards,
JKB
