KBI 311627 Issue Addressed: Some Versions Of AIX Servers Could Not Be Monitored By Telnet Option
Version
Argent Advanced Technology 5.1A-1801-A and below
Date
Monday, 26 February 2018
Summary
It has been reported that Telnet option does not work for some AIX servers
When doing connectivity testing, it fails at error ‘Failed to find login prompt’
Argent Advanced Technology has been using built-in Telnet functions implemented in IPWorks DLL, which is found not compatible with some versions of AIX Servers
Argent Advanced Technology has been enhanced to do Telnet through PLINK.exe
In order to instruct Argent AT Engine to use PLINK instead of built-in Telnet functions, set the terminal type to ‘PLINK’ in Licensed Node Properties
The issue has been addressed in Argent Advanced Technology 5.1A-1804-A
Technical Background
The issue is caused by the incompatibility between IPWorks DLL and AIX servers
The built-in Telnet functions works for majority of UNIX servers, including known LINUX flavors
Also, Telnet is regarded as an obsolete and insecure protocol
Use SSH instead if possible
Note: To use PLINK option, PLINK.exe should be installed on Argent AT Engine, preferably in Windows directory
Resolution
Upgrade to Argent Advanced Technology 5.1A-1804-A or above
