how do you connect through SSH to a device?



I need to create a VBScript (EXE/Script advanced Sensor) that execute a remote command to a linux device and to catch output for further translation in XLM output.. Linux device is reacheble only by SSH and your standard SSH Sensor (memory, load, etc..) work great! I tried "plink.exe -ssh" (cli version of popular PuTTY) but I've difficulty to make automathic the first ssh-key confirmation.. (I've to clone same sensor in a lot of Linux devices!) I found ChilKat.dll in your probe installation. Is that dll that you use to connetch through SSH? How can I use it in my vbscript?

Thanks a lot!! ..As usual!

We connect throught an internal Component via SSh to Linux devices which - I am afraid - is not accessible via VB Script.

Best Regards.

Ok.. So which windows user do you use in probe environment to launch exe/script? I need to make automatic the answers to "ssh first key echange". I gave ssh key-auth to user "administrator", but it doesn't work. I tried to force "Use Windows credentials of parent device" option, but it doesn't work too. Perhaps user "SYSTEM"?


Best regards

Script sensors are executed in the user-context of the PRTG Probe.

Have you managed to get your plink ssh connection running?

Running my ssh batch file from command line works perfectly. Do I run the batch file as a sensor, the output is always empty.

I'm running the PRTG Service with the local admin account - also tried domain admin.

Any further ideas?

Can a PRTG sensor start a batch script which starts a .exe? PTF-Launcher does not make sense in my case.

I have the same problem. If I run the plink batch file from command line all works fine. But if I test it as Notification in Paessler nothing happens.

Has anyone ideas?

For exe-/batch-files as notifications in PRTG, please see the following article for troubleshooting tips: How can I execute a batch file as notification?
