[pptp-server] Logging actual remote ip addr

[George Vieira]

I don't know how that can be... because your PPP shows up as... eg..

ppp1      Link encap:Point-to-Point Protocol  
          inet addr:10.0.0.1  P-t-P:10.0.0.68  Mask:255.255.255.255
          UP POINTOPOINT RUNNING NOARP MULTICAST  MTU:1500  Metric:1
          RX packets:231490 errors:0 dropped:0 overruns:0 frame:0
          TX packets:149905 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:10 

So how the hell is it reporting the external addresses...

Just add the following line into your /etc/ppp/ip-up.local and watch the
logs as your bring the link up

echo "$1 $2 $3 $4 $5 $6 " >> /var/log/pppconnect.log


Bring the link up and then look at this file.. let me know what you get..
Change IPs if it's internet addresses for privacy if responding to the
mailling list.

thanks,
George

I'd already tried that, but those variables contain the ip address of
the vpn, not the actual address of the remote client.
If the remote client internet address is 212.x.x.x, and the vpn address
assigned by pptpd to that client is 192.168.1.10, then $5 says
192.168.1.10, while I want 212.x.x.x.

Is there a way to change this behavior?

Thanks
