Re: listen on tcp port and log input ??
You may find one of my favorite utilities will do the trick: netcat. nc -l -p 3000 Listens on TCP port 3000 and once there is a connection, sends stdin to the remote host, and sends data from the remote host to stdout. You can redirect stdout to a file or use the -o option. See "man nc." In anycase, this is not what I would call a robust solution for something as important as billing. It is a nice way to begin snooping data from the router. Cisco routers output lots of billing data in a variety of ways. Your problem may be better solved with the IPPR, CDR, or RADIUS accounting records. /paul Marcel Welschbillig ([EMAIL PROTECTED]) said: > Dose anybody know of any programs i could use to open a port on a debian > box and log the data that comes in to a file ?? > > What i want to do is have a CISCO router send data that it recieves on > an AUX port to a tcp port on a linux machine and log the data to a file. > The data will be PBX billing data from a remote site. > > Any clues would be great ! > > Marcel

Does the router support remote syslogging? If so you could open a remote syslogging report and only let it reply to packets sent from the router with iptables or ipchains.
