[pptp-server] some little questions

[Patrick LIN]

hi,

i setup PPTPd server 
with :

- ppp-2.3.8
- linux-2.2.12
- SSLeay-0.9.0b
- ppp-2.3.8-mppe-others-norc4_TH7.diff
- ppp-2.3.8-patch1
- pptpd 0.9.17
- ipchains 1.3.9

i use on my options file :

lock
debug
auth
name proxy
refuse-pap
+chapms-v2
mppe-40
proxyarp


everything work well
but i am a very suspicious man and want to know what and why on
everything :))

this is a little sessions :

pptpd log:

Sep 21 13:09:16 proxy pptpd[2852]: CTRL: Starting call (launching pppd,
opening GRE)
Sep 21 13:09:19 proxy pptpd[2852]: CTRL: Ignored a SET LINK INFO packet
with real ACCMs!

i have some errors in this log 

1 - "Sep 21 13:09:19 proxy pptpd[2852]: CTRL: Ignored a SET LINK INFO
packet with real ACCMs!"

   what is it ?

2 - "Sep 21 13:09:20 proxy pppd[2853]: Cannot determine ethernet address
for proxy ARP"

   why? 

3- "Sep 21 13:09:50 proxy pppd[2853]: CCP: timeout sending
Config-Requests"


4 - i want to know if there are a way to control the simutaneous
connection
for the same username ?

thanks a lot
