PROBLEM: netfilter + 2.4.0-test10 causes connect:invalid argument

[John Buswell]

1. running 2.4.0-test10 with netfilter/iptables 1.1.2 ping/telnet gives
you invalid argument when connecting to ports on local interfaces.

2. when connecting to local interfaces (and/or local aliased
interfaces) from the local machine, ping/telnet (to any port) gives you a
connect: invalid argument. the connection works fine from remote systems
(eg. telnet remote 80 works, but telnet localhost 80 gives
connect: invalid). noticed same problem on a box in 2.4.0-test4.

3. networking 

4. Linux version 2.4.0-test11 (root@amdbox.opaquenetworks.net) (gcc
version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)) #3 Sat Dec 2

This is a _very_ strange problem. Nobody has erver reported this behaviour
to us (the netfilter developers).

I've never heared about it and never encountered it by myself. Sounds like 
it is a configuration issue.

could you please send me  the output of

lsmod
iptables -t filter -L -v -n
iptables -t nat -L -v -n
iptables -t mangle -L -v -n


btw: the netfilter mailinglist is probably the more apropriate place
for discussion of netfilter related stuff. See http://netfilter.samba.org
for subscription instructions.

Are you sure lo is up and configured (and that there's a route to
127.0.0.1 in your routing table that goes through lo)?  I think this can
cause such a problem.
