User Manual

Basic Remote Networking Incoming Connections
4-14
By default, incoming Telnet and Rlogin connections are not required to enter the login password.
To require the login password, use the Set/Define Server Incoming command, described on page
12-121.
❍ Username/Password Authentication
Enable authentication on the appropriate ports.
Figure 4-19: Enabling Authentication
If authentication should be performed before PPP or SLIP is running (while the port is still in
character mode), ensure that autodetection of PPP and SLIP is disabled (see Figure 4-20). If the
port automatically detects and runs PPP or SLIP, there will be no way to authenticate the user
because the local prompt cannot be accessed.
Keep in mind that PPPdetect and SLIPdetect will only need to be disabled on ports that have PPP
and/or SLIP enabled.
Figure 4-20: Disabling Autodetection of PPP and SLIP
In order for SLIP users to perform authentication, SLIPdetect must be disabled. SLIP users will
only be able to authenticate incoming connections while the port is in character mode; once the
port is running SLIP (for example, if the port is dedicated to SLIP using the Define Ports SLIP
Dedicated command), authentication cannot be performed.
If the port is configured to automatically run PPP and you’d like to use CHAP or PAP to obtain
a username and password from the incoming caller, enable remote CHAP and/or PAP
authentication on the desired port.
Figure 4-21: Enabling CHAP Authentication
Note: CHAP and PAP may both be enabled on the same port.
If incoming connections will be entering usernames to start a custom site, ensure that the site has
a local password. Callers will be required to enter this password in order to start the site.
Figure 4-22: Configuring a Site’s Local Password
Configure any databases that will be used for authentication and add the appropriate usernames
and passwords. See Chapter 11, Security, for configuration instructions.
