View 2 RepliesI install a Bind 9 with chroot in Centos 5, but the issue is the Reverse Name Resolution Zone File didn't create by default like other zone files, so i look into /var/named directory i don't find the reverse name resolution zone file even if i add this zone on named.conf
zone "1.168.192.in-addr.arpa" IN {
type master;
file "1.168.192.testsip.com.zone";
allow-update { key "rndckey"; };
notify yes;
};

2.Named.conf file conf...
3.Dig check is not working......

now I have a second 1.2T that i want to be /opt is there a way to set up 4kib block size in ext3 in the os install? or should I do it after the install? Is this block size even big enough?
I am no expert when it comes to BIND. I seem to be able to resolve NS and A and TXT records for my domain, but I cannot get the MX records to come out. Does anyone have an idea what might be wrong with my BIND zone file? I wonder if it might have something to do with the fact that my IP is currently on a policy Block List?

View 2 Replies View RelatedI chose -Server-, if this is more appropriate in -Networking-, just let me know. Basically, I need to be able to merge responses stored in a zone file with responses from an "upstream" authoritative server. I'm in the sad position of needing to "intercept" requests to *part* of a domain (but not restricted to a sub-domain!) and return results for *some* hosts that use an internally routed address, and results for the rest using the public internet addresses. Unfortunately, it's not my domain, so I can't just use views (although I suspect they could end up having some part to play in this, at least potentially)... but instead I have to actually send requests recursing to the other site's external DNS for any hosts my server doesn't have records for in the zone file.
Some background on the situation:
I work at a local government, which has a private link / VPN connection to a state government entity, and needs to use internal addresses for some of the state servers, which then get routed over an "internal" network link. But the state uses the same domain name internally and externally, just presenting views to internal clients vs. external clients. -- However, we are only being allowed access to certain of their servers through the internal link, which means that for any other servers that we don't have internal/private access for, we have to visit the public addresses just like anyone else on the internet... So, I can't just send all requests to their internal DNS and get responses, because we'd get IPs for some servers (e.g. their main web site) that we wouldn't then be able to reach using the internal network link.
For Example: Say I have a client machine, "client1", on my network ("my.net"), which uses "mydns1.my.net" for name resolution ... and which needs to access 2 servers on the state network, "private.st.us" and "public.st.us" -- so named based on how "my.net" needs to access them.
The external state DNS server/view ("ext-dns.st.us") responds to requests with something like:
private.st.us -- 1.2.3.456
public.st.us -- 1.2.3.457
(Those are just crap addresses, obviously.
The internal state DNS server/view ("int-dns.st.us") responds to requests with something like:
private.st.us -- 10.0.0.8
public.st.us -- 10.0.0.10
This works on their network because their own clients have access to all such IPs.
But for us, they only allow traffic flowing between "my.net" and their internal network to reach the 10.0.0.8 address, blocking all other address destinations. So, when "client1.my.net" asks "mydns1.my.net" for the address of "public.st.us", I need "mydns1" to recurse out to "ext-dns.st.us" to get an answer (1.2.3.457) and then return that IP to "client1" -- because "my.net" is blocked from accessing the server's 10.0.0.10 address. But, when client1 asks mydns1 for "private.st.us" I need to pull the IP (10.0.0.8) from a local zone file instead of asking either of the state DNS servers -- or optionally forward the request to "int-dns.st.us" I suppose -- because the state blocks access to certain services (which we need and are the whole cause of this problem!) via the public (1.2.3.456) address.

View 4 Replies View RelatedMy question is about DNS use of the $TTL directive. I realize the $TTL directive stands for TimeToLive, my question is why would you specify different TTLs in the zone file? I have a zone file with
$TTL 300
machine
machine
machine
TTL 3600
[code]....
I'm not sure why you just wouldn't specify the same TTL for all systems or at least not have all the 300's grouped together and all 3600s grouped together. The file I'm looking at has about 12 different groups of 300 and 3600 TTLs.
I installed the latest CentOS 5.5 in my PC. I added some public domain projects on it. Now how can I make another boot-able CentOS iso file with all the new projects I just added? In the other words, I try to create a boot-able CD with the CentOS and all the projects on it.

I would like to create a customized CentOS server, or it will serve me as a server (postfis) postfixadmin, Hylafax, webmail (Roundcube for example) and may be I would integrate suger crm.
If I create it all this server and it runs perfectly. my goal is I create a compilation or for example I install this distrubution and wonder just some configuration (eg IP address or the time just) knowing that by the end of the installation I find hylafax, postfix , and all AC roundecube install it remains for me to set them up! Taking the example of Elastix cd: www.elastix.org/ or it can make all AC (but its main role is the PABX).
