Chapter 3: Remote Operation Session Timers

3.4 Session Timers

There are timers on Utility Port, Telnet, and web control sessions that terminate them if

there is a lack of activity. Any action you take during a session automatically resets the

timer, and it starts all over again. The timers and their interactions are described below.

3.4.1 Utility Port Session Timer

The Utility Port Session Timer starts upon receipt of a character from the Utility Port. The

timer is reset upon receipt of every character. If no characters are received for 15

consecutive minutes, the session terminates.

When a Utility Port Session is in progress, Telnet cannot execute any commands to

TimeVault. The Utility Port Session must end before full Telnet access is possible.

3.4.2 Telnet Session Timer

The Telnet Session Timer starts upon receipt of a command line from Telnet, via the NET

Port. The timer is reset upon receipt of every command line. If no lines are received for

15 consecutive minutes, the session terminates.

Terminating a Telnet session drops the connection to the remote host. You can

immediately activate a new session by re-connecting and logging in again.

3.4.3 Web Control Session Timer

Once you are logged in to any Control Page, you can send HTTP requests from a web

browser, via the NET Port. The Web Control Session Timer starts as soon as it receives

such a request. The timer is reset upon receipt of every HTTP request. If no HTTP

requests are received for five consecutive minutes, the session terminates.

Terminating a Web Control session causes TimeVault to deny any further requests you

make for changes. You can immediately activate a new session by logging in again.
