Failed password for invalid user
Dear All ,

I have created a user named X and gave sudo permissions for it , So that it can access some commands as root.

This particular user can login to the server using SSH login through putty any where with in the network.

But there is some issue , when the same user is trying from UCMDB tool ( HP tool for discovery of machines ) through SSH protocol , it says connection failed.

On seeing the /var/log/secure in the Linux Server , it says the below log

Failed password for invalid user <username> from 172.X.X.X port 49401 ssh2

Can any body throw some light on this.

Thanks and Regards ,
Rj

Let me try to paraphrase your request.
You're sitting in front of a windows machine logging into your HP server using putty and the user X. From that server you're trying to discover other machines on the net, here: a linux server.
Are you sure user X has access granted on the linux server?

yes , rudi , access granted in the Linux Server.

There is no problem in the user connecting with putty.

When he tries with HP tool GUI with hardcoded passwords , it is not able to connect and connection refused.

Access from the HP machine is a totally different topic compared to connection from the windows machine. You need to implement/install both.

Dear All,

It got resolved as we added the hostname and ip in etc/hosts file.

Thanks all
