thnx and your are right. I changed the zone-file but it did not solve my original problem.

Try the following:

host $NAME_from_your_zone $IP_of_your_DNS

Do you get a correct answer, if so use tcpdump and check that you get the
right DNS.



thxn for your answer. I tried what you recommended and to make it short: I didnt get any new information. host-command gives correct answers, but when doing a "ping imap.local" my DNS or another DNS isnt even queried (tcpdump on lo and eth0) !!

here my outputs. I would be very happy if you could look over them to see if I missed something. thnx.



host gives me the correct answer in any settings:

# host imap.local
imap.local is an alias for phoenix.local.
phoenix.local has address 10.1.1.214

# host imap.local 127.0.0.1
Using domain server:
Name: 127.0.0.1
Address: 127.0.0.1#53
Aliases:
imap.local is an alias for phoenix.local.
phoenix.local has address 10.1.1.214

# host imap.local 10.1.1.214
Using domain server:
Name: 10.1.1.214
Address: 10.1.1.214#53
Aliases:
imap.local is an alias for phoenix.local.
phoenix.local has address 10.1.1.214


if running

#tcpdump -i lo port 53

I see the queries:

12:03:31.412303 IP localhost.33026 > localhost.domain: 22783+ A? imap.local. (28)
12:03:31.412682 IP localhost.domain > localhost.33026: 22783* 2/1/0 CNAME phoenix.local., (84)
12:03:31.413606 IP localhost.33027 > localhost.domain: 54842+ AAAA? phoenix.local. (31)
12:03:31.413810 IP localhost.domain > localhost.33027: 54842* 0/1/0 (81)
12:03:31.413976 IP localhost.33028 > localhost.domain: 48801+ MX? phoenix.local. (31)
12:03:31.414089 IP localhost.domain > localhost.33028: 48801* 0/1/0 (81)


when I run

#ping imap

I see my server querying for imap.local !!!

12:04:07.251898 IP phoenix.local.33028 > phoenix.local.domain: 24422+ A? imap.local. (28)
12:04:07.252240 IP phoenix.local.domain > phoenix.local.33028: 24422* 2/1/0 CNAME phoenix.local., (84)
12:04:07.252579 IP phoenix.local.33028 > phoenix.local.domain: 52112+ PTR? 214.1.1.10.in-addr.arpa. (41)
12:04:07.252754 IP phoenix.local.domain > phoenix.local.33028: 52112* 1/1/1 PTR[|domain]
12:04:08.257814 IP phoenix.local.33028 > phoenix.local.domain: 10046+ PTR? 214.1.1.10.in-addr.arpa. (41)
12:04:08.258095 IP phoenix.local.domain > phoenix.local.33028: 10046* 1/1/1 PTR[|domain]

and when I run

#ping imap.local

no traffic at all on lo nor on eth0 - not on port 53 and not on any other port !!!


I just dont get this !! This is kind of weird !! and starts to drive my crazy !!

thnx,
peter
