I unable to judge weather the script actually succeeded in connecting the host and failed only in executing the the command which I have assigned for $cmd.
Yes, I think the connection has succeeded and the error is coming from the Linux host - though I doubt very much that "pwd" is in fact unknown to that host.
On Windows, I'm apparently not set-up to use the auth_keyboard authentication to my remote Linux host - instead of auth_keyboard, I use auth_pubkey.
Then, in order to get your script to work, I have to slightly alter your run_testsuite() sub to:
sub run_testsuite {
my $cmd = $_[0];
my $ssh2 = $_[1];
my $chan2 = $ssh2->channel();
#$chan2->blocking(0);
$chan2->exec($cmd);
print "LINE : $_" while <$chan2>;
$chan2->close;
return 0;
}
Update: Actually, your original sub works fine for me so long as I precede the call to $chan2->shell(); with $chan2->blocking(0); .
With $ssh2->debug(0), that outputs (as expected):
Executing command...
==> Running pwd
LINE : /home/sisyphus
test passed done 0
Maybe give that approach a go instead - if only to verify that your remote Linux host does understand "pwd".
With $ssh2->debug(1) it outputs:
Executing command...
==> Running pwd
Net::SSH2::poll: timeout = 1000, array[0]
libssh2_channel_open_ex(ss->session, mandatory_type, strlen(mandatory_
+type), window_size, packet_size, ((void *)0) , 0 ) -> 0x2a6e3c4
Net::SSH2::Channel::getc(ext = 0)
Net::SSH2::Channel::getc(ext = 0)
Net::SSH2::Channel::getc(ext = 0)
Net::SSH2::Channel::getc(ext = 0)
Net::SSH2::Channel::getc(ext = 0)
Net::SSH2::Channel::getc(ext = 0)
Net::SSH2::Channel::getc(ext = 0)
Net::SSH2::Channel::getc(ext = 0)
Net::SSH2::Channel::getc(ext = 0)
Net::SSH2::Channel::getc(ext = 0)
Net::SSH2::Channel::getc(ext = 0)
Net::SSH2::Channel::getc(ext = 0)
Net::SSH2::Channel::getc(ext = 0)
Net::SSH2::Channel::getc(ext = 0)
Net::SSH2::Channel::getc(ext = 0)
LINE : /home/sisyphus
Net::SSH2::Channel::DESTROY
test passed done 0
Net::SSH2::DESTROY object 0x297d73c
which is also quite correct, but confusingly verbose.
If I include $chan2->blocking(0); (presently commented out), the debugging output becomes a little less verbose:
Executing command...
==> Running pwd
Net::SSH2::poll: timeout = 1000, array[0]
libssh2_channel_open_ex(ss->session, mandatory_type, strlen(mandatory_
+type), window_size, packet_size, ((void *)0) , 0 ) -> 0x29ce3c4
Net::SSH2::Channel::getc(ext = 0)
Net::SSH2::Channel::DESTROY
test passed done 0
Net::SSH2::DESTROY object 0x28dd73c
For your script, you could try setting blocking(0) and blocking(1) to see if that makes any difference.
You might also try replacing:
print $chan2 "$cmd \n";
with:
print $chan2 "$cmd\n";
And try anything else you can think of ;-)
