Hi there! I have a Linux box which has two network interfaces: the first one listens on a public IP address, the second listens on a local IP address. I'd like to configure xinetd so that an incoming request on port 110 (on the interface which has the public address) is redirected to our real POP3 server, which is on a local intranet. I installed Linux 7.2. I connect successfully to the port 110 of linux box, but as I'm connected the connection is closed. Probably it is a configuration mistake. Thanks Fiorenza Robinson s.r.l This is the xinetd.conf file # # xinetd.conf # # Copyright (c) 1998-99 SuSE GmbH Nuernberg, Germany. # defaults { log_type = FILE /var/log/xinetd.log log_on_success = HOST EXIT DURATION log_on_failure = HOST ATTEMPT RECORD only_from = 10.10.3.7 10.10.3.4 instances = 2 # # The specification of an interface is interesting, if we are on a firewall. # For example, if you only want to provide services from an internal # network interface, you may specify your internal interfaces IP-Address. # # interface = 127.0.0.1 interface = 10.10.1.6 # # # If you want to enable one of the following services, you only have to # comment it out.
