Welcome to the Linux Foundation Forum!

Lab 6.7


After I have edit the zone file for me, koumy.com.zone with content below, the command " named-checkconf -z koumy.com.zone " dosn't work.

TTL 30
@ IN SOA localhost. admin.koumy.com. (
2012012301 ; serial YYYYMMDDRR format
3H ; refresh
1H ; retry
2H ; expire
1M) ; neg ttl

            IN NS localhost.;

www.koumy.com. IN A
www.koumy.com. IN AAAA fe80::22c9:d0ff:1ecd:c0ef
mamou.koumy.com. IN A
tambassa.koumy.com. IN CNAME www.koumy.com.

;generate one hundred entries host1 thru host100
$GENERATE 1-100 host$.koumy.com. IN A 10.20.45.$

    Hi. I think the semi colon ";" is not necessary at the end of "localhost." Could you show the result of "named-checkconf -z koumy.com.zone "

    In the output I see that you are using "named-checkconf" but this command check a configuration file not a zone file.

    To test the zone file (koumy.com.zone) you create, use "named-checkzone"

    Syntaxe : named-checkzone "zone_name" "zone_file"

    Please change "TTL 30" by "$TTL 30"

    Hi, Sorry to heard you are having difficulty, perhaps I can help:

    The $ in $TTL indicates a command like the $GENERATE command.

    The trailing ; on the localhost line, indicates what follows is a comment. If there is no comment then the ; is unnecessary. The existence of the ; should not have any impact.

    A couple of quick questions, which distro and version are you using? Are you using one of the Linux Foundation VM's? Were you able to get the SOLUTIONS file ? The SOLUTIONS file contains a copy of the configuration files for the lab as examples.

    Please post any additional questions or concerns, thank you.
