Terminal Server Client
During the trial of connecting to the remote (Windows) desktop.
I used the terminal server client,
Please note: I have succeed in connecting many times before (no need question about the setting and the Windows other side work functionally).
Just sometimes it failed to connect and showed me:
ERROR: getaddrinfo name or service not known
I googled, seems something concerns the avahi,
it suggested to try:
$ service avahi-daemon stop
bash: service: command not found
I don't know how to proceed further,
