I am trying to connect w/ encryption enabled, but I get the following
error:

I will put my pptp 1.0.2 client configuration . I get the same error as
listed before with the Windows 98 clients. Both clients worked without
problems with PoPTop with no encryption.
I installed pppd here as in the PoPtop server (patched w/ rc4)
The linux client says :
(unknown)[391]: log[pptp_dispatch_ctrl_packet:pptp_ctrl.c:531]: Client
connection established.
(unknown)[391]: log[pptp_dispatch_ctrl_packet:pptp_ctrl.c:637]: Outgoing

The Windows client says that I was disconnected.

Execution script:

The name and remotename user here are the same as the ones defined in
the chap-secrets file of PoPTop
Any suggestion?
