xinetd services

Use chkconfig --list to see their status

[root@Hamming rc3.d]# chkconfig --list
readahead       0:off   1:off   2:off   3:off   4:off   5:on    6:off

etc

yum             0:off   1:off   2:off   3:off   4:off   5:off   6:off
xinetd based services:
        daytime:        off
        chargen:        off
        klogin:         off
        eklogin:        off
        ktalk:         off
        krb5-telnet:    off                      (These are the xinetd services)
        time:           off
        time-udp:       off
        daytime-udp:    off
        rsync:         off
        kshell:         off
        chargen-udp:    off
        echo-udp:       off
        cups-lpd:       off
        echo:           off
        gssftp:         off

Imagine we wanted to turn ktalk on. We would issue the following command.

[root@Hamming rc3.d]# chkconfig ktalk on

[root@Hamming rc3.d]# chkconfig --list
readahead       0:off   1:off   2:off   3:off   4:off   5:on    6:off

etc

yum             0:off   1:off   2:off   3:off   4:off   5:off   6:off
xinetd based services:
        daytime:        off
        chargen:        off
        klogin:         off
        eklogin:        off
        ktalk:         on
        krb5-telnet:    off
        time:           off
        time-udp:       off
        daytime-udp:    off
        rsync:         off
        kshell:         off
        chargen-udp:    off
        echo-udp:       off
        cups-lpd:       off
        echo:           off
        gssftp:         off
