Hi. The default setting is to only allow one concurrent session per user: # tl-config /vsmserver/max_sessions_per_user 1 To change this: # tl-config /vsmserver/max_sessions_per_user=0 # service vsmserver restart Zero means no limit. In order for helpdesk personel to connect to an existing user session, use the "Shadowing" functionality. In this case, add the privileged user to the configuration: # tl-config /vsmserver/allowed_shadowers=myadmin # service vsmserver restart Now the "myadmin" user can shadow other sessions.
