SSH connexion

Hi,

I try create a SSH connexion in my publication script. When i launch my script with command

iwperl publication.ipl args1 args2...

it works. But when I launch my script with teamsite as an external task, it doesn't work.

I have an error with the IO.

WARNING Use of uninitialized value in pattern match (m//) at C:/iw-home/iw-perl/lib/IO/Handle.pm line 350.
WARNING Use of uninitialized value in concatenation (.) or string at C:/iw-home/iw-perl/lib/IO/Handle.pm line 360.
FATAL  Can't call method "close" on an undefined value at C:/iw-home/iw-perl/lib/IPC/Open3.pm line 343.

Can anyone help me ?

Thanks

It sounds like you're using strict, which is good, but that you're

not scoping or initializing a couple of variables that you should be.

In your response, please attach your script. Reading about an error in line 350 is unfortunately meaningless without the proper context.

Are you by chance closing a handle that you never opened ?

The open3.pm is juste a perl librairy i didn't written it !
I'm using strict in my publication script.

I just call the function ssh frome librairy Net: Smiley Frustrated

SH and the function call the open3 function.

Okay, well giving error messages without providing (attaching) the code isn't going to get us very far in trying to provide help.

OK here is my code when i tried to call ssh

use Net:SH qw(ssh issh sshopen2 sshopen3);
use strict;


  my $user = "administrateur";
  my $host = "192.168.100.148";
  my $cmd = "ls -al";

  ssh("$user\@$host","$cmd");

and the librairy used attached!

for information i'm on Windows 2000 and the target is an AIX 4.3

Code fragment above does not look like external task code, more like rudimentary POC. If THAT does not work you have serious SSH issues
that have nothing to do to your code (like closed Firewalls, target SSH daemon not running, authentication Failure, etc...)

That said, your problem description indicates some object instantiation failure. External Task is your SSH Client, are
you sure that SSH Communication is allowed between TS Server and SSH Server? Did you provide proper RSA/DSA (whatever
you use) on the TS Server? External tasks run as SYSTEM in Windows, does this account have reading rights to C:\ssh or
wherever you keep SSH settings?

If I were you, I would also encapsulate ssh call into eval Block and log $@ afterwards.

Mdodin

Yes SSH communication is allowed.
If I run the script on DOS command, it works. The problem is when i'm using Teamsite to launch my script.

Mr_Cruise

Try hard coding the external task to run as the user that works from the command line.

Also what platform is this on Solaris or Windows ?

Mdodin

It's windows !

Mr_Cruise

What user are you logging onto the server as and have you hard coded that user into the external task ?

My connexion user is different from my teamsite user. I tried to hard coded that user. But the probleme still the same.

My connexion user is different from my teamsite user. I tried to hard coded that user. But the probleme still the same.

As I pointed out before in Windows External Task runs as SYSTEM regardless of the task owner (up to and including 6.5.x anyway)
