UDP/ tunnel
Hi,
I know tcp port tunneling can be done using ssh/putty. how about udp?
I have a scenario where a license server handsout licenses to machines in that network ONLY. I have a windows machine in a different subnet and even though the client software can see license server, while using the software the lic. server denies the permission because the windows machine is not in the same subnet as that of license server.
The license server here is windows. The service runs on port_a ( I think this should be 2047 UDP for opnet)
There are solaris / linux machines in the same network as that of license server which can be used for tcp/udp tunneling but I don;t know how I should make use of that. I do have account on those unix/linux machines and tcp forwarding/gateway ports is enabled in sshservers.
Is there anyway from client(windows), I can specify " localhost : port_a "as license server and so software will query to localhost:2047(udp). Can we forwards 2047 UDP to localhost:2047(tcp)?
Then do ssh tcp forwarding to linux machine for tcp port 2047. Then on remote linux machine forward tcp 2047 to localhost:2047(udp) and forward that udp 2047 to license server 2047 (udp)?
Is this technically possible? May be using nc(netcat) or udp_redirect?
or if there is any other way to let such users use the lic. servers successfully?
Please help..
Thanks in advance!

Two question here, but it's only one on the protocol point of view.

pdsend
pdsend(1) General Commands Manual pdsend(1) NAME
pdsend - send messages to pd on this or a remote machine SYNOPSIS
pdsend port-number [hostname] [udp|tcp] DESCRIPTION
Pdsend sends messages to pd(1), via a socket conection, from pdsend's standard input. This input can be any stream of Pd messages sepa- rated by semicolons. This is probably the easiest way to control pd from another application. The protocol used is easy to implement and is called FUDI. The port number should agree with the port number of a "netreceive" object within pd. The hostname is "localhost" by default and can be a domain name or an IP address. The protocol is "tcp" by default; this does a handshake to guarantee that all messages arrive complete and in their correct order; if you are sending messages locally or point-to-point you can often get away with the faster udp protocol instead. You can also use this to talk to a Max "pdnetreceive" object or even just a "pdreceive" in another shell. If you're writing another pro- gram you're welcome to just grab the sources for pdsend/pdreceive and adapt them to your own ends; they're part of the Pd distribution. SEE ALSO
