Re^2: Problems with Net::OpenSSH

[aeaton1843]

Oh how I wish they did. Cisco didn't add that functionality until IOS 15.0.1(M1) or so. Most of our routers are still in the 12.x train. I am actually controlling some F5's with Net::SSH in the manner in which you are suggesting. It works very well except for one thing. I wrote this module as a threaded app with ithreads and Net::SSH isn't thread safe. I found thanks to this site that Net::SSH::Perl isn't thread safe either. What I may end up doing is moving all of the Cisco routers into code that uses Net::SSH::Perl and use parent/child forking. I suppose I never really found out whether Net::OpenSSH is thread safe. I went looking for it and never found the information.

Net::OpenSSH is pure perl and does not use any globals, so it should be thread safe. Though I (BTW, I am the author) have never used it in threaded applications. IIRC, nobody have reported problems related to threads either.

Anyway, Net::OpenSSH can be used asynchronously, you don't even need threads to handle connecting in parallel to several hosts. Check also Net::OpenSSH::Parallel.
