Select "Trace" checkbox in the problematic UNIX server definition, run the test again and check relevant error messages in RunMonitor.log. It may give you a hint on what's going wrong with connection to the server.
We are experiencing connection issues to CentOS/VM clients from our Sitescope host server. We are receiving error "remote command error timed out reading (-996)" on our Sitescope console and the connection is dropped.
The client receives a connection request and allows the connection yet the Sitescope host only has a waiting hour glass. After about a minute or so the client receives a disconnect. We have verified that the host in fact does get logged on to the client with the ID and that the host gets disconnected after some time. We are unclear as to what Sitescope is requesting and or what it is doing during the wait period.
Any help to resolve connectivity issues from Sitescope host to CentOS/VM is greatly appreciated.
Do the connection credentials you inserted in SiteScope belong to a user that is defined on the VM as a ksh shell user? In that case the shell might take longer to respond to SiteScope's connection than the designated connection timeout.
Please try to check 'Wait for SSH connection prompt' checkbox and enlarge the 'SSH prompt timeout' as required (both parameters are in Preferences > Infrastructure > General).
Remember to restart SiteScope after updating values in the Infrastructure Preferences.
