Red Hat Bugzilla – Bug 196655
netstat: when using --interface=ethX 1, the counter remains unchanged.
Last modified: 2017-03-02 07:32:24 EST
When using netstat and wanting to only get statistics from one interface, none
of the counters get updated and therefore, the output keeps unchanged.
How to reproduce it:
% netstat --interface=eth0 1
It will always show the same counters. Always reproducible.
Reproducible with RHEL4U4beta, seems fixed in FC5.
Basically the issue came from having if_readlist_rep() declared static from the
lib/interface and being called from netstat.c. This prevented the output to be
updated from /proc.
Attached you will find the patch that fixes the issue, please let me know if you
need more details about it.
