Using remote access services to connect to IDN domains

Your application must be IDN-compliant to use IDNs with remote access services such as FTP, Telnet, or SSH to connect to a domain. Additionally, you must configure the services to use the character set UTF-8 to enable correct interpretation of IDN domain names.

Connecting to IP-based domains

To connect to an IP-based domain using a non-IDN compliant client (such as Telnet/SSH/FTP on Linux):

  1. 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

  1. Enter the user name and password.

Connecting to name-based domains

To connect to a name-based domain using a non-IDN compliant client (such as Telnet/SSH/FTP on Linux):

  1. 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

  1. Enter the user name (in the format <user@ascii_encoded_domain>) and password.
