AW: AW: AW: AW: Read Client Hostname

I tried now to get the hostname for output in the Debug Log but the variable is always empty but I don't know if my code is correct.

I added a line mslog(s, proc, LOG_DEBUG, "Hostname '%s'", tmsg->hostname); after the if (tmsg->hostname) block but in the log I always get 
main: IP:Port  Hostname '' or main: IP:Port  Hostname '(null)' and some lines after that then I will see X-CSTP-Hostname: value.

I added the code in the main-worker-cmd.c

Can you tell me what I did wrong or I used the wrong file to add the code.

Most likely you need to modify config.c (and ocserv-args.def) to add new config file variables. The update should be triggered at main -worker.c when the CMD_SESSION_INFO message is received by main which contains the hostname.
