Subject: Networking problems with 2.6.1-rc2
Date: Wed, 7 Jan 2004 17:49:08 +0100	[thread overview]
Message-ID: <20040107164908.GA24660@louise.pinerecords.com> (raw)

The box I'm seeing this on has a single inet interface "eth0,"
which is connected to LAN.

	# ip addr add 172.27.0.1/16 brd + dev eth0 label eth0:1
	$ nmap -sP -T Insane '172.27.*.*'

There are no live addresses from the 172.27.0.0/16 range on the LAN.
After about a minute into the ping sweep, nmap starts printing messages like:

	Strange read error from 172.27.4.26: Transport endpoint is not connected
	Strange read error from 172.27.4.27: Transport endpoint is not connected
	Strange read error from 172.27.4.28: Transport endpoint is not connected
	...

and dmesg reveals these errors:

	Neighbour table overflow.
	NET: 46 messages suppressed.
	...

Then, trying to issue a simple "ping 172.27.5.5" results in:

	connect: No buffer space available

I'm unable to reproduce the problem with a 2.4 kernel.
