| Subject: | Script hanging when trying to return data from STDOUT |
I'm running ActivePerl 5.8.6 build 811 and have been trying to get a
simple script using net-ssh-w32perl (0.05) to run on a Windows XP SP1
platform connecting to a SuSE linux box. I suspect there is an issue
with stdout for the following reason.
Reading configuration data C:\Documents and
Settings\Administrator/.ssh/config
Reading configuration data /etc/ssh_config
Connecting to xxx.xxx.xxx.xxx, port 22.
Socket created, turning on blocking...
Remote protocol version 1.99, remote software version OpenSSH_2.9p2
Net::SSH::Perl Version 1.24, protocol version 2.0.
No compat match: OpenSSH_2.9p2.
Connection established.
Sent key-exchange init (KEXINIT), wait response.
Algorithms, c->s: 3des-cbc hmac-sha1 none
Algorithms, s->c: 3des-cbc hmac-sha1 none
Entering Diffie-Hellman Group 1 key exchange.
Sent DH public key, waiting for reply.
Received host key, type 'ssh-dss'.
Host 'xxx.xxx.xxx.xxx' is known and matches the host key.
Computing shared secret key.
Verifying server signature.
Waiting for NEWKEYS message.
Enabling incoming encryption/MAC/compression.
Send NEWKEYS, enable outgoing encryption/MAC/compression.
Sending request for user-authentication service.
Service accepted: ssh-userauth.
Trying empty user-authentication request.
Authentication methods that can continue:
publickey,password,keyboard-interactive.
Next method to try is publickey.
Next method to try is password.
Trying password authentication.
Login completed, opening dummy shell channel.
channel 0: new [client-session]
Requesting channel_open for channel 0.
channel 0: open confirm rwindow 0 rmax 16384
Got channel open confirmation, requesting shell.
Requesting service shell on channel 0.
channel 1: new [client-session]
Requesting channel_open for channel 1.
Entering interactive session.
Sending command:
Requesting service exec on channel 1.
channel 1: open confirm rwindow 0 rmax 16384
=======> Hangs Here.
When it runs OK (with the stdout redirect to a file) I get this:
Sending command: ls
Requesting service exec on channel 1.
channel 1: send eof
channel 1: open confirm rwindow 131071 rmax 32768
channel 1: rcvd eof
channel 1: output open -> drain
channel 1: obuf empty
channel 1: output drain -> closed
channel 1: close_write
channel 1: send close
input_channel_request: rtype exit-status reply 0
channel 1: rcvd close
channel 1: full closed
=======> script exits normally
