telnet Proxy Use

Before a client can connect to a remote host when the telnet proxy is active, the client must first connect to the telnet proxy. In the following example, the telnet proxy is running on the host Screen, and the user wants to connect to the remote system foo.com.

riyal% telnet Screen
SunScreen telnet Proxy Version: 2.0
Username@Hostname: edison@foo.com

At the password prompt, you type the password for the proxy authentication. The telnet proxy would compare the specified user name and password to the list of valid proxy users and their passwords. If the user name/password are correct and the connection is allowed, the user is presented with a login banner for the machine foo.com.

You can have the Screen decrypt incoming traffic from a client before passing it to the proxy. It requires two rules. The following is an example of using the telnet proxy with SunScreen SKIP:

edit> add rule telnet proxyclient localhost SKIP_VERSION_2 ...edit> add rule telnet proxyclient proxyserver PROXY_TELNET

Likewise, you can have the Screen encrypt the connection from the proxy to the backend server using a similar pair of rules:

edit> add rule telnet localhost proxyserver SKIP_VERSION_2 ...edit> add rule telnet proxyclient proxyserver PROXY_TELNET
