I have installed vCenter6.7 on ESXi 6.7 host. In the vCenter appliance I'm seeing the below log message continuously in /var/log/vmware/messages log file.
2020-07-15T08:20:01.112590-07:00 glhc-vcsa sshd 39441 - - pam_mgmt_cli(sshd:auth): authentication successful, but failed to connect to applmgmt service (254):
2020-07-15T08:20:01.029120-07:00 glhc-vcsa cli - - - vmware.vherd.linux_cli.cli Error getting authentication cookie from applmgmt service. Verify that the applmgmt service is running and that the method requested to obtain the cookie requires authentication.
However when I login into the vCenter appliance and check the status of applmgmt service it is showing as running. However I have started restarting the service and still the issue is not solved.
How to resolve this issue?
This mostly occurs if you have some external party such as monitoring solutions which try to login to VC with root and have password error or login failure .
Do "grep -c "Failed password for root"
for var/log/vmware/messages .
You should be able to find the IP from where this failures are occurring .
This error doesn't has or indicate any production impact though
