does someone know about pop3
i have setup a sendmail server... everything is working fine except that i cant telnet my server on port 110 outside of my server ( on another network segment ) anyone suggestion ...
|
Do you have a pop3 server running? It'll have to be started independently of sendmail just incase you haven't and of course if it's sendmail you want to telnet it'll be port 25.
But then again doh, you're saying you can telnet within the server so ignore that. Any entries in hosts.deny? |
my smtp on port 25 is working no problem there... the port 110 is replying only on my server
hosts.deny if intact nothing inside except comments ... |
And you can telnet to sendmail from outside I assume.
What distro you using? How is the other seg connected via a hub, switch etc? No firewall rules? Try restarting everything. So many questions and I'm probably still not helping I'm afraid :) 'Tis a strange one. |
i can telnet to port 25 no problem.
redhat 9 full update 2 different internet providers no fire wall rules i restarted .. same thing very strange |
at the CLI type
/sbin/iptables -L if you have a list of stuff there...you have rules blocking the port.. |
in witch file do i add my rule ... i want to give access to a mac adress
|
if you don't want a firewall
just do /sbin/iptables -F however, if you do want one.. you will have to find which file on the system holds your rules... a search on the internet for MonMothma's Firewall script should give you a good, and easily manipulated script. you may have to turn off the firewall service, ie, check /etc/init.d/ for a firewall script, maybe replace it with the above mentioned script. do a google for iptables and firewall scripts... this is a huge topic, there is much to be covered, and learned.. |
Great you found it ... its working ... guess i have to read on firewall rules... is it possible that my rules are in rc.local ...
Thanks |
