Привет всем!
Есть в распоряжении 2 Linux сервера. На одном стоит pptpd сервер на другом, соответсвенно pptd клиент.При попытке соединится с сервером соединения не происходит. В логах сервера вот такие записи (см. ниже). Если в качестве клиента использовать клиент win 2000, то соединение происходит и все работает. В чем проблема?Oct 26 17:15:44 localhost pptpd[4534]: CTRL: Client 192.168.0.222 control connection started

# Sample Poptop PPP options file /etc/ppp/options.pptpd
# Options used by PPP when a connection arrives from a client.
# This file is pointed to by /etc/pptpd.conf option keyword.
# Changes are effective on the next connection. See "man pppd".
#
# You are expected to change this file to suit your system. As
# packaged, it requires PPP 2.4.2 and the kernel MPPE module.

# Network and Routing# If pppd is acting as a server for Microsoft Windows clients, this

# addresses to the clients. The first instance of this option
# specifies the primary DNS address; the second instance (if given)
# specifies the secondary DNS address.
#ms-dns 10.0.0.1
#ms-dns 10.0.0.2# If pppd is acting as a server for Microsoft Windows or "Samba"
# clients, this option allows pppd to supply one or two WINS (Windows
# Internet Name Services) server addresses to the clients. The first
# instance of this option specifies the primary WINS address; the
# second instance (if given) specifies the secondary WINS address.
#ms-wins 10.0.0.3
#ms-wins 10.0.0.4# Add an entry to this system's ARP [Address Resolution Protocol]
# table with the IP address of the peer and the Ethernet address of this
