Re: Executing command over forwarded port
Thanks Andreas.But this iam implementing on Windows which does not support socketpair().

Here is a step by step description how I would implement it. a) Create a ssh session and connect b) Create a forward channel c) Create a socketpair() d) One end of the socketpair() is used to read data and write it to the forward channel, and vice versa. e) Create a new ssh session f) Set the other fd of the socketpair() as the fd for the new session g) Connect and exec ... It should work just fine with a socketpair() but you can also create a tcp socket and connect to the port on localhost. I suggest you read the SSH RFC to understand port forwarding better and read the manpages about sockets and socketpair. -- Andreas Schneider GPG-ID: CC014E3D www.cryptomilk.orga...@cryptomilk.org -- Raghaw Shukla Software Engineer(AutoPilot Development Team) Aurora Integrated Systems,Bangalore.
