ATMTCP(8)

NAME
atmtcp - set up ATM over TCP connections

SYNOPSIS
atmtcp [-b] -l [lclport]
atmtcp [-b] -c host [rmtport]

DESCRIPTION
atmtcp establishes TCP connections and configures them as virtual ATM devices. Such pairs of "ATM over TCP" devices are connected as if they were real ATM adapters linked by a cable or fiber, i.e. PDUs sent on a given VPI/VCI are received at the other end on the same VPI/VCI.

The optional port arguments are used to run atmtcp on a different port than the default port (8401).

OPTIONS

-b  Run in background (i.e. in a forked child process) after initializing.

-l  listen for an incoming connection. Only one connection is accepted.

-c host
    connect to an instance of atmtcp running on the specified host.

RESTRICTIONS
Only AAL PDUs are exchanged, no segmentation or reassembly is performed. That implies that using different AALs (e.g. AAL5 and AAL0) on either side will reveal limitations of this emulation. atmtcp continues to run during the the whole lifetime of the connection. Forcibly terminating atmtcp will force all VCs to be closed and the virtual ATM device to be removed.
