Subject: [pptp-server] encryption problem?


I read the document which titled "Setting up PPTPD on Linux Kernel 2.4
HOWTO". I followed the instruction which mentioned in the document. But I
got following error when I use VPN with "encrypt data" from Win98 to make a
connection.(I am using Kernel 2.4.7)
 
Nov  9 15:44:42 localhost pppd[1480]: pppd 2.4.0 started by root, uid 0
Nov  9 15:44:42 localhost pppd[1480]: Using interface ppp0

Did you add the proper aliases to your /etc/modules.conf file???? i.e.
 
alias char-major-108 ppp_generic
alias tty-ldisc-3 ppp_async
alias tty-ldisc-14 ppp_synctty
alias ppp-compress-18 ppp_mppe
alias ppp-compress-21 bsd_comp
alias ppp-compress-24 ppp_deflate
alias ppp-compress-26 ppp_deflate
 
Nov  9 15:44:46 localhost pppd[1480]: Cannot determine ethernet address for
proxy ARP 
Nov  9 15:44:46 localhost pppd[1480]: local  IP address 192.168.0.235
Nov  9 15:44:46 localhost pppd[1480]: remote IP address 192.168.1.235  
 
Although this is a totally unrelated problem, in most cases, if it is not
fixed, you will be unable to access any nodes on your LAN from the remote
PPTP client. To fix:
 
1) Change the remote ip address range to be within the same network address
range as your LAN. i.e. 192.168.0.x
 
2) If you must break out your remote PPTP clients into a separate network,
then you will need to look at using a combination of ip aliasing and routing
so that the PPTP server's interface can properly determine that it can act
as a proxy arp for the remote PPTP clients.
 
Nov  9 15:44:46 localhost pppd[1480]: CCP terminated by peer
Nov  9 15:44:46 localhost pppd[1480]: Compression disabled by peer.
Nov  9 15:44:46 localhost pppd[1480]: LCP terminated by peer

Nov  9 15:44:46 localhost pppd[1480]: Connection terminated.
Nov  9 15:44:46 localhost pppd[1480]: Connect time 0.1 minutes.
Nov  9 15:44:46 localhost pppd[1480]: Sent 112 bytes, received 130 bytes.
Nov  9 15:44:46 localhost pppd[1480]: Exit. 
 
How could I locate the module? 
 
If you properly applied the MPPE patches to the kernel and pppd, then the
resulting modules should be in the following directory:
 
/lib/modules/<kernel rev>/kernel/drivers/net
 
Many thanks...
