firewalling. :-)
I'm a bit baffled as to why I am seeing the following on a system here:
1) I can "telnet localhost 25" on system "A" and that works (gets through
to sendmail just fine).
2) If instead I used the command "telnet A 25", I get the following:
"telnet: connect to address xxx.xxx.xxx.xxx: Connection refused" 3) I get the same "Connection refused" message when trying to telnet
to port 25 on system A from any other system on the LAN (as I guess
I would expect).4) "iptables" appears to be allowing everything, so far as I can tell.
I am new to iptables, so I am not sure what else I might try, but an
"iptables --list" command shows "policy ACCEPT" for all three chains.
5) If there's perhaps some old ipchains stuff in the way here, I don't
know how to find it and kill it. 6) Since sendmail isn't listed amongst the xinetd daemons, that's not
where it is enabled/disabled...So what am I missing here???
tnx, K
