Using SSH protocol

Krishnakumar M — Wed, 23 Jan 2002 09:54:04 GMT

Is there any equivalent to 'rcmd' system call when we are using the SSH protocol for secure communication.
What I am asking is that, is there a system call and not any command line option to use the secure protocol SSH.

Well, in theory, anything that you could do with the old r-commands you can do with ssh, but I don't know that there's a system call out there that'd hook in nicely -- you might be better off posting this question over at one of the ssh developer sites.

ssh2 does.

Just append the remote command after the ssh command. (man ssh for openssh 2.9.something)

eg: ssh2 user@host ls

My apologies for the previous answer.

If thought things through and if i were really desperate enough i guess i would try to hack together a library using the openssh program.
Take the ssh program and rename main() to rcmd(params here). compile it as a library and use that.
However i doubt that's what you have in mind so indeed contacting ssh might not be a bad idea.

what is it exactly that you're trying accomplish? if you just need to initiate running a remote command from your program you could try running the remote ssh command using the exec() call. you would probably want to use RSA/DSA authentication.

if you are willing program in Perl, you could also check out the Net-SSH-Perl Perl module from CPAN.
