NAME

       qpsmtpd-forkserver - Fork-on-demand server for qpsmtpd

SYNOPSIS

       qpsmtpd-forkserver [options]

DESCRIPTION

       qpsmtpd-forkserver is the qpsmtpd frontend script which binds to the SMTP TCP socket and forks as clients connect.

OPTIONS

       --port port, -p port
	      Binds to a specific port, instead of the default 2525.

       --user user, -u user
	      On  startup,  switch to run as user instead of the starting user.  Applies only when started as root (as is normal when listening on
	      port 25).

       --limit-connections limit, -c limit
	      Accept at most limit simultaneous connections.  Inbound connections beyondthis limit will be deferred or refused.

       --max-from-ip limit, -m limit
	      Accept at most limit simultaneous connections from any given IP address; does not override --limit-connections, if set.

       --listen-address addr, -l addr
	      Bind to the local address addr, instead of the default behavior of binding to all interfaces.  Can be specified  multiple  times	to
	      bind to more than one interface or local address.

       --detach, -d
	      Detach from the controlling terminal at startup, to run as a standalone daemon.  See also --pid-file.

       --pid-file filename
	      Upon  startup, and after daemonizing if applicable, write the process ID to filename, for use by sysvinit control scripts or similar
	      utilities.

VANESSA_SOCKET_PIPE(1)					      General Commands Manual					    VANESSA_SOCKET_PIPE(1)

NAME

       vanessa_socket_pipe - Trivial TCP/IP pipe based on libvanessa_socket

SYNOPSIS

       vanessa_socket_pipe [options]

DESCRIPTION

       A  TCP/IP  pipe	is a user space programme that listens for TCP/IP connections on port on the local host and when a client connects makes a
       connection to a TCP port, possibly on another host. Once both connections are established data sent on one connection  is  relayed  to  the
       other, hence forming a bi-directional pipe.

       Uses include enabling connections to specific ports on hosts behind a packet filter.

       This code is intended primarily as an example of how many of the features of libvanessa_socket work.

OPTIONS

       -c|--connection_limit:
	      Maximum  number  of  connections	to accept simultaneously. A value of zero sets no limit on the number of simultaneous connections.
	      (default 0)

       -d|--debug:
	      Turn on verbose debuging to stderr.

       -h|--help:
	      Display this message.

       -L|--listen_port:
	      Port to listen on. (mandatory)

       -l|--listen_host:
	      Address to listen on. May be a hostname or an IP address.  If not defined then listen on all local addresses.

       -n|--no_lookup:
	      Turn off lookup of hostnames and portnames. That is, hosts must be given as IP addresses and ports must be given as numbers.

       -O|--outgoing_port:
	      Define a port to connect to. If not specified -l|--listen_port will be used.

       -o|--outgoing_host:
	      Define host to connect to.  May be a hostname or an IP address. (mandatory)

       -q|--quiet:
	      Only log errors. Overriden by -d|--debug.

       -t|--timeout:
	      Idle timeout in seconds.	Value of zero sets infinite timeout.  (default 1800)

       Notes: Default value for binary flags is off.
	      -L|--listen_port and -o|--outgoing_host must be defined.
