Using the pairing method, you are not asked to give the client a name. The installer uses the local short hostname of the operating system to create the initial configuration.
Furthermore, a client gets two tags by default. The current country and city taken from the current public IP address. This might be unpresize and you want to delete or change it.
If you want to change the name of a system, you must do this in the rport client configuration file. The configuration files is
/etc/rport/rport.conf on Linux
C:\Program Files\rport\rport.conf on Windows
Open the file with a text editor. Scroll done some lines. You will find the setting
name = "<SOME-NAME>".
Change the name to your needs.
Just a few lines below the name, you'll find the tags. Change them to your needs and save the changes.
After any changes to the configuration file, you need to restart the client.
On Linux, execute
systemctl restart rport.
On Windows use the service manager or from a console execute:
sc stop rport
sc start rport
