Description Pekka Savola 2000-07-06 07:07:42 EDT
Tcpdump gives a warning when running it:

setsockopt(PACKET_RX_RING): Protocol not available

This isn't aesthetically pleasing ;)
Comment 1 Pekka Savola 2000-07-10 15:30:28 EDT
I tracked this to libpcap's pcap_open_live before figuring out this was
just another compile issue.

'rpm --rebuild tcpdump*.src.rpm' fixes the problem.
Comment 2 Jeff Johnson 2000-07-12 00:08:01 EDT
This should be fixed by tcpdump-3.4-22 rebuild.
Comment 3 Pekka Savola 2000-07-27 08:08:54 EDT
This bug resurfaced in beta5 / wasn't fixed. :-(
Comment 4 Tim Waugh 2000-07-27 09:47:19 EDT
tcpdump-3.4-26 works fine here: can you check that's what you have?
Comment 5 Tim Waugh 2000-07-27 09:49:00 EDT
Sorry, my mistake; a rebuilt 3.4-26 works, but the binary package was still
Comment 6 Pekka Savola 2000-07-31 16:44:32 EDT
Upped the priority and severity.

IMO this isn't something we want to see in Winston final.

Comment 7 Jeff Johnson 2000-08-04 16:47:40 EDT
This smells like Yet Another Trip through the build system with final kernel
headers should
fix. Please reopen if tcpdump-3.4-27 still has a problem.
Comment 8 Pekka Savola 2000-08-10 11:09:47 EDT
This happens in RC1 too :-(
Comment 9 Jeff Johnson 2000-08-11 11:02:19 EDT
Ahh, the problem is compiling *with* 2.4 headers. Error message removed in
