PROGRAM:
NAME
afserver - active port forwarder server
SYNOPSIS
afserver [ options ]
DESCRIPTION
Afserver is a port forwarding program designed to be efficient and easy
to use. It listens for incoming afclient connections at listenport
(default listenport is 50126). After successful client authorization,
afserver listens for incoming user connections. When a new user
connection is opened, all the data is redirected to previously
connected afclient, which redirects it to the specified destination
host:port.
EXAMPLES
afserver
program starts with default options (become a daemon)
afserver -v
verbose mode is enabled (program won't enter daemon mode)
afserver -n localhost -l 5435 -m 6375
program will listen on localhost:5435 for users and on localhost:6375
for clients
