bind problems in centos 6.0

Post by malak33 » 2011/12/10 14:39:16

hi guys, im kinda new here. Just about finished school and trying to set up a centos server to go for some certs. Anyway, I'm trying to get my DNS up and running I'm having some troubles.

This is also on a virtual box. If you need anymore information just let me know.
here is the log messages that generate when i try to do a
service named restart:

[code]
Error in named configuration:
zone localhost/IN: loaded serial 2006123106
dns_rdata_fromtext: 127.0.0.rev:7: near 'IN': extra input text
zone 0.0.127.in-addr.arpa/IN: loading from master file 127.0.0.rev failed: extra input text
zone 0.0.127.in-addr.arpa/IN: not loaded due to errors.
_default/0.0.127.in-addr.arpa/in: extra input text
zone example.org/IN: loaded serial 2009123106
dns_rdata_fromtext: example.org.rev:3: near '3H': not a valid number
zone 15.2.0.10.in-addr.arpa/IN: loading from master file example.org.rev failed: not a valid number
zone 15.2.0.10.in-addr.arpa/IN: not loaded due to errors.
_default/15.2.0.10.in-addr.arpa/IN: not a valid number
[/code]
Thanks guys

So it tells you that you have two problems. One on line 7 of the file for zone 0.0.127.in-addr.arpa and one on line 3 of the file for zone 15.2.0.10.in-addr.arpa. The second one doesn't like the "3H" that you've specified (presumably meant to be 3 hours) so specifying that as 10800 will probably fix that (# of seconds in 3H). If you can't see a problem with the one on line 7 then post it here and see if someone else can.

In the /var/named/example.org.rev you are missing a close bracket ")" to match the opening one on line 2 - it should be just prior to the first line starting "IN". The other error appears to be in a file called 127.0.0.rev and you haven't posted that but I'd hazard a guess that it's exactly the same error.
