Is it really required to explicitly close the Net::SSH2 connection, Net::SSH2 channel or the Net::Telnet connection in Perl?
If so what would be the consequences of not closing them?

1Close voters: I think the question is pretty clear. What happens if you don't explicitly close an SSH or Telnet connection before script exit? This is similar to [How severe is it if we do not close a file in Perl?](http://stackoverflow.com/q/12702869) – ThisSuitIsBlackNot Mar 20 '17 at 16:34

What I don't like about the question is that it sounds like they are trying to prove something wrong, but don't include a source. With a small edit, I'd vote to reopen. – simbabque Mar 20 '17 at 16:41

What I don't get is what "in perl" has to do with the question? – Tanktalus Mar 20 '17 at 17:56

@Borodin: I have updated the question. Apologies for the confusion. Kindly help me out with the query. – Sujeet Padhi Mar 20 '17 at 18:22

If you don't close channels/connections, they will be automatically closed for you from the objects destructors when they go out of scope. The advantage of doing it explicitly is that you can catch errors. – salva Mar 21 '17 at 07:45

@salva The question has been reopened now, so can you post that as an answer? You're uniquely qualified to answer this one :) – ThisSuitIsBlackNot Mar 21 '17 at 15:43
