Question

I want to run the following code, but its not working:

int main ()
{
     execlp("ssh user@192.168.170.155", "ssh user@192.168.170.155", NULL);
     return 0;
}

But if I replace ssh with any other command(say ls) its working fine.

Thanks,
Yuvi

Did you read the man page of execlp?

You probably want

int main() {
  execlp("ssh", "ssh", "user@192.168.170.155", NULL);
  perror("execlp ssh");
  return 1; // failing exit code if execlp failed.
}

The execlp could fail (e.g. if ssh is not in your $PATH)
