ok. time is becoming critical and i will need to reboot soon. this is a
mass invite to diagnose a very hard to uncover TCP bug.

synopsis: outbound TCP connections fail. all other types of packets
in/out work fine.

strace snippet:
# strace -f telnet 0
[...]
write(1, "Trying 0.0.0.0...\n", 18Trying 0.0.0.0...) = 18
socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 4

Works fine for me here. Maybe you need to increase
/proc/sys/net/ipv4/ip_local_port_range?

this is a production system and i'll need to reboot it soon. if you would
like to get information on this, please contact me asap. IMPORTANT:
email <david@wgn.net>, NOT <david@kalifornia.com> as of course...sendmail
is transferring my mail via tcp :)

Then fix your reply-to field. Also you've been unsubscribed from all
the Linux lists at vger due to these bounces, sorry.
