Operating Systems Linux Debian tcpdump filter (mis)behaviour Post 302505374 by Hollinch on Thursday 17th of March 2011 07:30:32 AM

As above,

tcp port 80
tcp port http

Or simply
port 80
or
port 22
Etc

Just thinking. If tcpdump and libpcap are not at fault here (as I have used two different versions of both with the same result), the only thing remaining would be the network card driver I suppose. Can this be of influence in this behaviour? I would expect not, as the filter applies to libpcap, but...?

Thanks

Roland Dreier <rolandd@cisco.com> BUGS
The network synchronization between client and server instances is weak, and does not prevent incompatible options from being used on the two instances. The method used for retrieving work completions is not strictly correct, and race conditions may cause failures on some systems. libibverbs August 30, 2005 IBV_RC_PINGPONG(1)
