Summary

When using PLINK to monitor LINUX/Unix server, both connectivity test and running Relator can times out without actually running Rule script

When doing connectivity test interactively using Engine {local}, following line shows in the testing terminal first:

     Access granted. Press Return to begin session

Only after user presses Enter key, the session continues

This is actually caused by new anti-spoofing feature introduced in PuTTY v0.71

Technical Background

When using PuTTY v0.71 or later, running Relator will be stuck at the anti-spoof prompt

As Engine knows nothing about it, Engine will simply wait until times out

Resolution

User can take one of following to address the issue

1. Download and install PuTTY earlier than and including v0.70

   Make sure put PLINK.exe in Windows\System32 folder

2. Specify string ‘-no-antispoof’ as additional arguments in Node Properties of License Manager
   
3. Upgrade to most recent Argent Advanced Technology and use built-in SSH library instead of PLINK to monitor LINUX/Unix server
