How to reset a telnet session

 

Symptom:

A Dialogic IMG Integrated Media Gateway ('IMG') or Dialogic MSP 1010 Multi-services Platform ('MSP') allows only one telnet session (IMG 1010, IMG 1004 and MSP) or ssh session (IMG 2020) to be active at any given time.  Once a telnet / ssh session is established, subsequent connection attempts will fail with "Sorry, session limit reached". However, there are times when an administrator or support engineer may need to access the IMG or MSP using telnet / ssh while another active (or inactive) session has already been established.


Solutions:


IMG 1010 and MSP:
1.  Dialogic Gate Control Element Management System (GCEMS) or Dialogic Multi-services Platform SwitchKit® (Development Environment) users running Dialogic ClientView may reset the telnet object by navigating to the 'Telnet Client Enable' object, right-clicking it and selecting the 'Reset Telnet Client' option:

Note: the 'Remote IP Address' value is not updated in real-time; deselect the 'Telnet Client Enable' object and then reselect it to refresh the current view.

2.  MSP users who have developed their own applications may send the following API message:

Prior to resetting the current telnet session, the following indication is displayed: '> Connection closed by foreign host'

IMG 2020:
Access the IMG 2020 WebUI, right-click in the BN2020 object and select "New SSH Server" and commit this object. Now you can use the "Reset SSH Client" button to disconnect a current ssh session.
