Note Submitter: jr at cnb dot uam dot es ---- I have made a class that allows usage of SSH from within PHP. It has several major differences with these routines, and you may want to have a look at it. The class I wrote (SExec) emulates 'exec' methods over SSH. It tries to mimic the major php command execution methods/functions over SSH (proc_open, popen, etc..) and provides for interactive sessions with remopte hosts. The main differences are: - it uses OpenSSH commands to do the work. This has IMHO pros and contras: it allows you to update your SSH infrastructure without recompiling PHP, and only requires a single SSH infrastructure. - it is really simple to use, and imitating other PHP functions, rather intuitive as well - it is independent of PHP version. Well sort of, I have tried it on PHP4 and PHP5, but should be portable to older versions with little work - it is highly efficient: by multiplexing connections over a single channel (available since OpenSSH 3.8) it only requires one authentication. We routinely launch batches of thousands of SSH commands, and the difference is amazing - it allows you to have various simultaneous connections with various servers: this is useful for multiplexing job launchs and providing fallback mechanisms (just make various instances) If there is any interest on this code, just drop me a note and I'll post more details.
