The regulatory domain is represented by an ISO / IEC 3166-1 alpha2 country code. By default, setregdomain attempts to determine the appropriate country code by examining the target of the .IR /etc/localtime symbolic link. That information is used to look-up the matching country code in the .IR /usr/share/zoneinfo/zone.tab file. The country code look-up may fail. This could be due to faulty or incomplete information in the .IR /usr/share/zoneinfo/zone.tab file, or the use of an actual file rather than a symlink for .IR /etc/localtime , among other possibilities. In those cases the system administrator should define a COUNTRY environment variable in the .IR /etc/sysconfig/regdomain file. This value will be used as the country code and the country code look-up will be skipped. .SH "FILES" .BR /etc/sysconfig/regdomain .BR /etc/localtime .BR /usr/share/zoneinfo/zone.tab .SH "SEE ALSO" .BR iw (1)
