Hi Alex the version is KES 11.1.1.126 and some have upgraded to 11.4.0.233 - both versions have some issue...but not all hosts

Version of KSC and Agent? KSN settings KSC and KES policy?

 

[ramonz]

So the versions are as follow:

 

• KSC 11
• workstation agents: some are 11.1.1.126 and some have updated to 11.4.0.233
• server agents: are all 10.1.2.996 and all of them are green and healthy
• KSN set to be active on all hosts
• Policies all in order

 

I have a feeling that this is a problem with versions - could KSC 11 be ‘too old’ for the hosts which turned to 11.4.0.233? but i cant understand why some of the red ones are on 11.1.1.126...

The agent is comming with the KSC - the versions you mentioned are protection products.

KES11.3 and KES11.4 are supported with KSC/agent 12 only

Do you have KSN-Proxy configured in the KSC and/or KES Policy? Then you need TCP 13.111 open from agent to KSC

How do you explain that some of the hosts are working normally and showing green if KES11.3 and KES11.4 are supported with KSC/agent 12 only and I am running KSC 11 ?

[alexcad]

I only recommend operating a supported environment. Problems with KSN are probably related to the policy settings and the ports.
