Re: SSH2 - Asynchronous Opens & Synchronous Commands
in thread SSH2 - Asynchronous Opens & Synchronous Commands
Thanks for the suggestion Salva, but I don't believe your modules will suffice in this case. Net::OpenSSH lacks sufficient shell support for this use case, and Net::OpenSSH::Parallel is does not fit the use case (only the connect() calls are to be done in parallel - I can't queue up a bunch of commands and run).
I know you strongly believe the idea of having to interact with the shell is a bad one, but that is the requirement. The framework we've built is used to verify command sets executed in the remote shell environment of hosts and devices. I can't just connect, run a command, and close. I need to connect, send a remote command (which could be a shell builtin like cd), check the status, run a command, inspect the output, and so on. It is an automated interaction. Combining commands with '&' isn't an option - they need to be executed individually and evaluated. Basically, I need the full functionality of Net::SSH::Expect, which we've also implemented, but this task to implement Control::CLI/Net::SSH2 is to replace the use of Net::SSH::Expect, as Net::SSH::Expect is not thread-safe.
If Net::OpenSSH had shell support like Net::SSH2, I'd try it again in a heartbeat.
Net::SSH2 is also thread-safe. At least it is when the entire test for a device is contained within a thread. The questing being asked is what is the best method of making only the connections in parallel (for performance reasons) and still allow the remainder of the test to be performed serially?
