how to use telnet command in vCenter appliance putty session

Telnet is the command which we can easily use to check the service status of the remote system.

Ex if we can telnet to vCenter server from our desktop using port 443, we can say that web services of the vCenter is up

As an alternative option, we can use curl command. Please refer the below screen capture

 

curl -v telent://vcsa-01a:443
