How to telnet from bamboo
Asked by Aziz Fall:

Hello,

I would like to send a telnet from bamboo through a script. But it is not working. Is there any way to telnet from Bamboo server? Is there any configuration to do as prerequisite before launching a telnet.

I tested the telnet from a windows prompt on the bamboo server and it works. But not from the script i have created on bamboo.

Regards,

Aziz.

Radu show how to use unix/linux style pipe to send interactive commands to telnet

but I doubt that will work on windows.

Its really impossible to say what the solution would be without knowing more about what your trying to do.

body: Again telenet is an interactive program. As Radu's link points out.

If you don't want to use ActiveX as suggested in the link, then look at python. There is a telnet lib and you could start using more robust technologies.

body: Hello Guyz,

Thank you all for your responses.

To give you more details:

1) In fact we created a VBS script on which we put the different commands (credentials and requests) to access to our remote system.

2) This VBS script is called by a windows script (.bat) with below lines:

     :: Open a Telnet window
       start telnet localhost
       :: Run the script 
        cscript SendKeys.vbs

3) When we execute the windows script (.bat) from the bamboo server it is working fine.

4) Then we tried to add the script as a Script task in Bamboo. But from our Bamboo plan the script seems to be called (we put some logs to check it) but the telnet seems to be not executed.

That is actually our issue and the only way we have to connect to our system is through telnet.

Can you help,

Thank you in advance,

Regards,

Aziz.

body: @Radu Dumitriu convert your "Reply" to "Answer" I think this is what Aziz is looking for.


author: Krystian Brazulewicz
body: Aziz - I'm pretty sure that your ability to run telnet to the other machine needed some configuration. Make sure this configuration is also valid for an account that Bamboo is running on. I see you're mentioning Windows so this will be Local System account

Edit: Also as @Radu Dumitriu mentioned ssh provides more secure method of connecting between hosts (although is not available on windows out of the box)

body: ```
(echo username; sleep 1; echo password; sleep 1; echo "put_command_here"; echo "quit" ) | telnet host
```

If you're on telnet =\> you have little or no security concerns, therefore it may worth to ask yourself if rsh/rlogin would help you (I know it's out of fashion but they'll do the job)

Anyway I would use ssh anytime:

```
ssh user@host "put_command_here" 
```

(but configure it not to ask a password via RhostsRSAAuthentication)

body: well, Krystian \& Paul have a point here. I always assume that people use decent OSes. Yes, on windows just install cygwin or something. Piping should work on windows also, but ....
