[pptp-server] pptpd problem

[Igor N. Kolomiyets]

Hi,

i'm trying to connect linux box to pptpd on another linux box with 128-bit
encryption enabled.
What's happening is when i run pptp on client node it terminates with error:

ERROR!  Connection timed out.

on server side log file consists the following:

 and so on

on client node in pptp.log is the following:

both ends have chap-secrets file something like:

guest    *    guestpwd    *
domino    *    domino    *

No errors except timeout were produced.
Does anybody experienced something similar?

Best regards,
igor.
