Subject: Handles to sockets are not released
Date: Mon, 17 Mar 2008 11:56:58 +0100
To: bug-Net-SSH2@rt.cpan.org
From: r.liebig@telenet-ag.de
Using Net::SSH2 Version 0.18 following program does not release handles properly. ------------------------------------------------------------------------------------------------------------ use Net::SSH2; $host="host"; $user="user"; $pass="pass"; for(my $i=0; $i < 100; ++$i){ print "Doing round $i\n"; my $ssh2 = Net::SSH2->new; my $rc=$ssh2->connect($host); print "rc=$rc\n"; $ssh2->poll(250); my $type=$ssh2->auth(username => $user, password => $pass); print "type=$type\n"; my $chan = $ssh2->channel(); $chan->blocking(0); $chan->shell(); print $chan 'hostname'."\n"; print $chan 'hostname'."\n"; print $chan 'cat /etc/passwd'."\n"; while(<$chan>) { print ; } print $chan 'exit'; $ssh2->disconnect; $ssh2 = undef; sleep 10; } ------------------------------------------------------------------------------------------------------------ Using the unix-command pfiles following statements can be seen: 10: S_IFSOCK mode:0666 dev:258,0 ino:25969 uid:0 gid:0 size:0 O_RDWR|O_NONBLOCK FD_CLOEXEC sockname: AF_INET 0.0.0.0 port: 0 11: S_IFSOCK mode:0666 dev:258,0 ino:26416 uid:0 gid:0 size:0 O_RDWR|O_NONBLOCK FD_CLOEXEC sockname: AF_INET 193.96.234.131 port: 55584 peername: AF_INET 193.96.234.132 port: 22 With every round a handle like handle 11 above turns into one like handle 10 which is kept forever. If the disconnect statement above is dropped, the handle 11 stays as is. By means the handle is not closed properly. This behaviour is only recognised, if just user and password are used.
