NAME
trampoline - forward incoming calls to another address
SYNOPSIS
aux/trampoline [ -9 ] [ -a altaddr ] [ -m netdir ] addr
DESCRIPTION
Trampoline can be used in a service file (see listen(8)) to link an in‐
coming call to another address that provides the service, typically on
another machine.
Trampoline dials addr and copies data between that connection and its
own standard input and output.
The options are:
-9 The connection carries only 9P messages. In this case trampo‐
line will relay whole messages at a time.
-a altaddr
Dial altaddr and relay between the two network connections, ig‐
noring standard input and output.
-m netdir
Restrict forwarding to particular machines. Netdir must be the
incoming call directory. Trampoline finds the caller's MAC ad‐
dress m and checks that ndb(6) contains an entry with ether=m
and the attribute trampok. If no such entry is found, the call
is rejected.
