I'm having a problem with the Net::SSH2 module. My case is: I use the channel's exec() to execute a command. I start pulling back the output. The command causes the remote side to reboot (expected) but the connection dies uncleanly (no EOF) When I get into this state, eof() returns true. read does not return undef. Basically everything I'd expect to be reporting problems is not. So, how do I tell that my connection has died? Thanks.
