I have a set of interfaces (created by Emerging Technologies' frame relay
driver), etha500, etha501, and etha502. When I check its status using
netstat, i.e.:
netstat -n -I etha500
...I get accurate output, like so:
Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll
etha5 1500 <Link> 339288 0 304238 0 0
etha5 1500 205.215.5.4 205.215.5.5 339288 0 304238 0 0
However, when I use the wait (-w) option, like so...
netstat -n -I etha500 -w 5
input (eth0) output input (Total) output
packets errs packets errs colls packets errs packets errs colls
0 0 0 0 0 719553 1 753094 9 3040
0 0 0 0 0 368 0 380 0 1
It gives me statistics for eth0 instead, which is inactive. Some software
of mine uses netstat to display up-to-date status information on various
interfaces, so I'm wondering if this is a condition I can correct. I
thought it might be a problem with the driver, but since netstat gathers
the stats correctly without the -w option, the values are obviously there.
I browsed through if.c from netstat briefly, but nothing slapped me in
the face. There seems to be a difference between how intpr() and
sidewaysintpr() gather their data, but I don't see it. Any ideas?
Please CC replies to me, as I'm not on the list...
