Problem in starting Nodemanager in weblogic 8.1

Hi,

I am facing one problem, when monitoring NodeManager.
I am using Weblogic 8.1
On browser it says
[[NodeManager:300033]Could not execute command ping on the node manager. Reason: weblogic.nodemanager.NodeManagerException: [CommandInvoker: Failed to send command: 'ping to server 'null' to NodeManager at host: '15.76.221.205:8002' with exception [Security:090504]Certificate chain received from nta21205.india.hp.com - 15.76.221.205 failed hostname verification check. Certificate contained nta21205 but check expected nta21205.india.hp.com. Please ensure that the NodeManager is active on the target machine].]
& on console
it says
<Feb 21, 2003 1:21:23 PM GMT+05:30> <Warning> <Security> <BEA-090482> <BAD_CERTI
FICATE alert was received from nta21205.india.hp.com - 15.76.221.205. Check the
peer to determine why it rejected the certificate chain (trusted CA configuratio
n, hostname verification). SSL debug tracing may be required to determine the ex
act reason the certificate was rejected.>
I am unable to get the error
please help
Thanx

You must config SSL between nodemanager and weblogic server

Jack,
We also got a similar error like 'failed hostname verification check. Certificate.......'. When we checked the registry.xml in $BEA_HOME$ the <host> tag was holding a different name than my machine name. So we re-installed the server again after which the <host> tag was holding a proper value and we are able to run NodeManger successfully. Please post ur solution if it is not the above mentioned one.

Thanx Chao Wang, Karthik Prabu.
But I was able to do that without any SSL configuration !!
I just changed status of Host Verification to NONE.
& that worked for me.
As I am not doing this for any production environment, it is safe.
But in realtime production environment, hostname verification is required for security purposes.

Hi Jack, I have a question about that !
How i can change the Host verificacion to NONE, how I can force without SSL?
Thanks in advance!

you should start weblogic.Server with the property:
-Dweblogic.security.SSL.ignoreHostnameVerification=true

in the startWeblogic.sh or whatever you use to start...

in any case if you reall y desperate you can start the MS with the startManagedServer.sh <servername>, that should usually work...

Eventually try also
-Dweblogic.webservice.client.verbose=true
-Dweblogic.security.SSL.verbose=true
-Dssl.debug=true
-Dweblogic.StdoutDebugEnabled=true

oops sorry I am having some trouble editing messages, and there is not an option to delete a previous message (??)

I had a similar problem, check that the hostname and listen address are the same on the Node Manager. Note that if the hostname is fully qualified the listen address on the node manager should also be the same. Click on machines > machine name > node manager
