"connection refused" on port 993, when not coming from localhost
I have pretty much a default installation of Redhat 8.0. I'm trying to enable secure imap but I seem to get a "connection refused" whenever I try to come in from anywhere other than localhost. I'm not aware of any firewall settings and my hosts.deny and hosts.allow are empty. I can connect to a bunch of other ports (e.g. 80, 22, 25) but not 993 (or 143; I haven't even bothered with regular imap). A bit more info:
"netstat -nl" produces output including the line
tcp 0 0 0.0.0.0:993 0.0.0.0:* LISTEN
$ more /etc/xinetd.d/imaps
# default: off
# description: The IMAPS service allows remote users to access their mail \
# using an IMAP client with SSL support such as Netscape \
# Communicator or fetchmail.
disable = no
socket_type = stream
wait = no
user = root
server = /usr/sbin/imapd
log_on_success += HOST DURATION
log_on_failure += HOST
If I go to my Redhat Services Configuration, it shows imaps as being "Currently running at Runlevel 5". I have run "/etc/init.d/xinetd restart" several times....
My /etc/xinetd.conf file is the usual one, specifying 993 as the imaps (tcp) port. I've created ssl certificates, yadda yadda yadda, but I still can't connect to port 993!! :-( Like I said, I *dont* have a firewall.
I had a problem earlier with sendmail, e.g. that sendmail would by default refuse all connections on port 25 that were not coming from localhost. Is there some similar default that I need to disable for port 993?
What to do?
