openssh unix dev - Dec 2008 - Can't connect client when runned from Windows Service

Hi,

I have a client on a Windows machine that connects through openssh on a
linux server.
I have this script (tunnel.cmd):

@echo off
:RUN echo Connecting?
"C:/Program Files/OpenSSH/bin/ssh.exe"  -R 40201:localhost:50300 -o
TCPKeepAlive=no -o ServerAliveInterval=15 -o ServerAliveCountMax=2 -i id_rsa
visma at 10.55.40.123
echo Restarting in 10 seconds?
GOTO RUN

It is runned from another application that starts as windows service.
When i run the same script manually it makes the connection to linux
machine. Is not working when we run it from the application that starts as
windows service.

Any help greatly appreciated.


Thanks in advance,
Adriana

'-ddd' ssh command line parameter and output redirection will help you.

Sincerely Your, Dan.

Thanks for the advice Dan, will try it.

Script makes the connection if is started manually from command line, or if
program is started as executable. But when i start it as windows service i
see it running in task manger (cmd.exe and ssh.exe) but it doesn't make the
tunnel with the server.

I've tried different user accounts to make it connect as service. Only one
that could connect is if is runned under the user that is logged on, but
that means user has to input username and password.
Is it a way to make connection if is runned as Local service or Network
Service or Local System?

Thanks in advance,
Adriana

Also, what does '-ddd' do? Looked on manual and only thing i could find
is

    *-D* [*bind_address*:]*port*
             Specifies a local ``dynamic'' application-level port
forwarding.

Googled it also but didn't find anything about it

Thanks again,
Adriana

First of all, always supply the full path for the id_rsa file so that
the file is found regardless of the current working directory.

Second, run ssh with -N and -T. Check out the ssh(1) man page to
learn more about their meaning. -T is important for all automated
runs.
