Using remote access services to connect to IDN domains
If your application is IDN-compliant, you can use the IDN representation of a domain name to access domains when you use remote access services such as FTP, Telnet, or SSH. Additionally, you must configure the services to use the character set UTF-8 to enable correct interpretation of IDNs.
Important: If your application is not IDN-compliant, you must use the ASCII-encoded representation of the domain name to access the domain.
To connect to an IP-based domain using a non-IDN compliant client (such as Telnet/SSH/FTP on Linux):
Connect to the domain using the domain name or IP address.
#ssh <ascii_encoded_domain>
For example, to connect to the domain färgbolaget.nu using its ASCII encoded representation xn--frgbolaget-q5a.nu, type:
#ssh xn--frgbolaget-q5a.nu
Enter the user name and password.
To connect to a name-based domain using a non-IDN compliant client (such as Telnet/SSH/FTP on Linux):
Enter the user name (in the format <user@ascii_encoded_domain>) and password.
