timeout when telnetting to port 25
Hi,
I have this problem, when telnetting on my own machine to localhost 25 it works
when I try it from another host nada
I ran tcpdump -s 1492 port 25 , when telnetting i dont get any results. (externally to my machine)
I flushed all my iptables, even put logging on in my iptables for all connections towards port 25...
and dont get any attempts/loggings when telnetting to port 25...
any idea's ? I use exim4 but I checked the config and can't find any probs there + thats apllication layer, I definately seem to have a problem in a lower layer...
i'd assume that exim is only listening on loopback or something... do you have a local_interfaces directive in your exim.conf? can you connect to the external ip address from the machine itself? that would connect to the interface but bypass any other networking.
when I do exim4 -bh mywanip I get :
>>> host in hosts_connection_nolog? no (option unset)
>>> host in host_lookup? yes (matched "*")
>>> looking up host name for 195.207.150.236
>>> IP address lookup yielded mydomain.com
but I dont get the exim prompt... So I think you're right :-)
----
Any idea where I have to config this please ? my exim4 seems to have 60 config files :-/
