SYMPTOMS
You may not be able to use a telnet client program on a UNIX workstation to connect to another computer through a machine that is running Microsoft Windows NT Server 4.0 and Microsoft Proxy Server 2.0.



CAUSE
This behavior can occur if the telnet client program on the UNIX workstation is not fully compatible with Socks version 4.3a.



RESOLUTION
To resolve this issue, use a telnet client program that is fully compatible with Socks version 4.3a on the UNIX workstation.



MORE INFORMATION
Socks is a cross-platform mechanism that establishes secure communications between client and server computers. The Socks Proxy Service supports Socks version 4.3a and allows network users transparent access to the Internet by means of a Proxy Server. The Socks Proxy Service extends the redirection provided by the WinSock Proxy service to non-Windows platforms. It uses Transmission Control Protocol/Internet Protocol (TCP/IP) and can be used for TELNET, File Transfer Protocol (FTP), Gopher, and Hypertext Transfer Protocol (HTTP). The Socks Proxy Service does not support applications that rely on the User Datagram Protocol (UDP).
