[pptp-server] ip-up script and real client's IP

[Yoss]

Hi.
Is there any posibility to recognize real IP of the client in ip-up 
script? 
A login and pasword is for me not enough.
Until now I was makeing it with perl script, which gives me IP upon 
analysis of logs and `ps`. But now, when number of my clients will 
incerase up to one hundred this way can be uncertain.

Or Is there any posibility to change pptpd to transmit real IP of 
client to pppd? In example as linkname option? (as far as I know this 
option is unused by pptp).

Thank you in advance.
