Hi All,

I am getting the following exception. when running a shell command

ksh -c export TERM=vt100; ssh -p 2261 -N -f -L<local-port>:loghost:2361 IP_ADDRESS

localport will be replaced by valid port number greater than 1024.

The following are the exception which i am receiving.

java.io.IOException: SSHksh: not found

Can anyone tell me the exact reason for this error?

Your early response is highly appreciated.

Redirecting out- and input with > and < is a feature of your shells, but not possible from runtime.getRuntime().exec ...

And maybe more than one command, concatenated with ; is a problem?

Here is an article about pitfalls with runtime:
