[pmwiki-users] Recipe ActionLog

[Petko Yotov]

I checked one of your wikis and found what appears to be a server-side 
configuration issue, rather than a problem with the ActionLog recipe or 
with your installation.

The $_SERVER['REMOTE_ADDR'] variable, which normally contains the 
visitor's IP address, has the same value as $_SERVER['SERVER_ADDR'], 
which contains the server's IP address. In this case, the value also 
matches the domain's DNS A record, suggesting that PHP is seeing the 
server's public IP address instead of the visitor's actual IP address.

The $_SERVER['HTTP_X_FORWARDED_FOR'] variable does contain the visitor's 
IP address. However, this header can be spoofed and should only be 
trusted when it is set and validated by a trusted reverse proxy.

This suggests a possible server-side networking or reverse proxy 
configuration issue. For example, if a reverse proxy forwards requests 
to PHP-FPM without correctly configuring the forwarding headers or the 
web server's handling of the original client IP, PHP may see the proxy's 
IP address or another server-side address instead of the visitor's IP.

To investigate further, the hosting provider should check the web server 
configuration and raw access logs, specifically the original 
connection's remote IP address, to determine where the requests are 
coming from and how the client IP address is being handled.

Based on these findings, I recommend opening a support ticket with your 
hosting provider and asking them to investigate the server's handling of 
the original client IP address and correct the configuration if 
necessary. This is not something that can normally be fixed within your 
wiki installation itself.
