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, IMG 1004 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.
