Hi,
I created an OpenVPN admin interface, which I want to show the actual
connected server of a client. The normal "state" command in the admin
interface does not provide the information. The attached patch adds an
extra argument to the "state" result which shows the server's IP. Like
this:
[root@VPN00059 ~]# echo state | nc 0.0.0.0 5000
>INFO:OpenVPN Management Interface Version 1 -- type 'help'
for more info
1128286300,CONNECTED,SUCCESS,,145.66.1.1
END
[root@VPN00059 ~]#
James Yonan once told me that this actualy changes the admin API, so it
may break some admin interfaces. For those however who can use it I
attached the patch.
Rolf
