Subject: wrong mtu value in /proc/net/route
Date: Thu, 25 Jul 2002 22:34:11 +0100 [thread overview]
Message-ID: <20020725223410.A18965@steely.transient> (raw)
I've found something strange going on in 2.4 kernels - when I run
'netstat -r' I get the routing table from /proc/net/route. The MSS
value reported is only 40 bytes, and when I run 'cat
/proc/net/route I'm told that the _MTU_ is 40 bytes. I thought the MSS was
supposed to be the MTU - 40 bytes, not 40 bytes in
total, where the MTU for ethernet is 1500. If I run ifconfig, it reports the
correct MTU of 1500 for eth0 and 16463 for lo. This computer has a NetGear
FA311 card, and is running 2.4.19-pre7-ac2, though I've also seen this
happening on a 2.4.18 kernel.
