I have a really weird problem - maybe it was always like that or it only
happened since I upgraded, I'm not sure -
I have a CentOS 5.1 box and for some weird reason I can't connect using
TCP to a server running on the same machine, either through localhost or
through the eth0 IP address. Connections from outside work great and the
httpd is happily serving users across the network.
When I try to connect, even something simple such as
telnet localhost 80
I get a timeout:
# strace -f telnet localhost 80
...
connect(3, {sa_family=AF_INET, sin_port=htons(80),
sin_addr=inet_addr("127.0.0.1")}, 16) = -1 ETIMEDOUT (Connection timed
out)
write(2, "telnet: connect to address 127.0"..., 59) = 59
close(3) = 0
write(2, "telnet: Unable to connect to rem"..., 63
/etc/hosts.deny was the immediate suspect, but its empty. IPTables was
on, but is set to always allow "lo" (and port 80 among others) and
turning it off didn't help. So what can I check next ?
Thanks in advance
