Telnet Capabilities; Single Administrator; System Timeout - D-Link DI-106 Series User Manual

telnet will still be available provided you assign the router an IP
address.

Telnet Capabilities

Single Administrator

To prevent confusion and discrepancy on the configuration, your
DI-106 or DI-106M will allow only one terminal connection at any
time. The router also gives priority to the RS-232 connection over
telnet. If you have already connected to the router via telnet,
you will be logged out if another user is connecting to it via the RS-
232 cable. Only after the other administrator has been disconnected
will you be able to telnet to the router again.

System Timeout

When you are connected to your DI-106 or DI-106M via telnet,
there is a system timeout of 5 minutes (300 seconds). If you are not
configuring the device and leave it inactive for this timeout period,
the router will automatically disconnect you.
