Hi

I am running ESXi5 & used to connect through a vSphere Client supplying below details & it was connecting fine.

IP: 10.0.0.1

username: root

password: ********

but today when i tried to login  it gave me Certificate Warnings as usual & i Ignore it as usual. the moment i Ignore it, it prompt me below error:

I can have physical access to the server so I tried changing the password of root user also & tried to install the certificate also but no impact.

ssh is enabled on in that server but when i try to connect through putty, its giving me error like below:

which log should i interpreat can any one suggest me or how can i troubleshoot it?

thanks

Please double-check if SSH is enabled on Host. Use this to check settings - http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2004746

Re: root logon issue, has anything changed recently ?

I have already enabled the SSH, but its not connecting from putty. so i thought to reset the host setting & restart the host. after starting up its asking the root password to change the IP. i think it has reset the root password also. can you tell me what is the default password of root?

thanks

oh! the default root password is blank !!

Friends it is not resolving my problem the errors are same even though i reset all my config.

if i reinstall the ESXi5 then how can i save my datastore?

thanks

When re-installing ESXi 5 there is an option to preserve existing VMFS datastores (just choose "preserve" there, I think it is the default, but I'm not sure now). After re-installing you just need to add the VM's to the host's inventory again: Browse the datastore in the vSphere client, find the VMs' .vmx files and register them.

Instead of re-installing you could also try to reset the root password following the (unsupported) instructions here: http://vm-help.com/esx/esx3i/Reset_root_password.php

But before you try all that ... are you sure that this is not just caused by a keyboard layout mismatch? Are you able to log on at the console/DCUI as root?

The broblem is solved. I reinstall the vSphere Client and it worked fine. And probably aftering reinstalling ESXi5 again & enabling SSH, through putty its accessable. but i am unable to understand how the vSphere Client got affedted anyway.

thanks a lot friend for your suggestions.
