Для начала стоит отключить файрволлs на Windows и Linux (если не проблема, то можете настраивать, но смысл?). Затем для Windows производим настройку так, как это рекомендовано в справке одной хорошей программы: RAdmin HelpRemote Administrator doesn't work with a modem directly. To use it in a modem to modem connection you need to configure dial-up networking on both the server and client sides.

Radmin uses a TCP/IP connection between computers. So, you need to install and configure this service on the computer which will accept calls:


· Routing and Remote Access Server for Windows XP/2003
· Remote Access Server for Windows NT/2000
· Dial-Up Networking Server for Windows 95/98/ME

Then configure the server to use TCP/IP protocol.

On the client side you should install dial-up networking, configure it to use the TCP/IP protocol only and make a call using dial-up networking. After connecting you can find the IP address of the remote server in the properties of the Dial-Up connection (usually some tray icon appears). Alternatively, you can find this address in the Dial-Up monitor from the Control Panel.

Use this IP address as the host address to connect to the server using Radmin Viewer. As a rule in a modem to modem connection 192.168.55.1 IP address is used.. А потом идем на форум Линукс и там задаем вопрос о приеме входящих нуль-модемных подключений :)
