/usr/sbin/check-hostname
System Administration Commands check-hostname(8) NAME check-hostname - check if sendmail can determine the system's fully- qualified host name SYNOPSIS /usr/sbin/check-hostname DESCRIPTION The check-hostname script is a migration aid for sendmail(8). This script tries to determine the local host's fully-qualified host name (FQHN) in a manner similar to sendmail(8). If check-hostname is able to determine the FQHN of the local host, it reports success. Otherwise, check-hostname reports how to reconfigure the system so that the FQHN can be properly determined. FILES /etc/hosts Host name database /etc/nsswitch.conf Name service switch configuration file /etc/resolv.conf Configuration file for name server routines EXIT STATUS 0 Fully-qualified host name was determined. >0 Fully-qualified host name could not be determined.
