I was following this instruction to validate my debugger configuration on Web Server. I uses a remote server whose FTP connection has been tested, but I get this warning message saying
Remote host is configured as 'localhost' despite server host is probably not local
My first question is: what does "remote host" and "server host" refer to respectively?
I know remote host is the setting xdebug.remote_host, and according to the xdebug documentation, it is "the host where the debug client is running".
This makes me confused: Isn't the debug client the IDE I am running on my local machine?
If yes, then shouldn't "the host where the debug client is running" be my local machines's IP address? If yes again, should I configure xdebug.remote_host to be my IP?
I tried setting it to my IP, the warning message does't show but it doesn't feel right because later I tried it with a random IP the message also doesn't show.
Secondly, the xdebug documentation also says that this xdebug.remote_host setting will be ignored if xdebug.remote_connect_back is enabled." Although not quite sure what this setting does, I set it to be "On", as the picture shows:
I was hoping this will eliminate the warning message, but it is still there. So how do I get rid of this message?
