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
getuid() = 0
setuid(0) = 0
connect(4, {sin_family=AF_INET, sin_port=htons(23), sin_addr=inet_addr("0.0.0.0")}, 16) = -1 EAGAIN (Try again)
write(2, "telnet: Unable to connect to rem"..., 52telnet: Unable to connect to remote host: Try again) = 52
last night i was able to use TCP and establish an outbound connection.
the difference was it did a bind() just before connect.
today ssh also fails.
-------------
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 :)
if i have no responses within ~8 hours, i'll reboot the machine.
one of the network gurus -please- contact me. it is not easy to duplicate
this situation and it may be months before i catch it again. i have more
notes on the subject.
