I want to compare zone file counting and same name, not records etc of master and slave dns server so that i sure both server contains same copy of the files at a time. Any utility to compare such files in linux?

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?
Code:
This is the entry which iam seeing in my /var/log/messages. code...
because of the issue now i cant able to write the zone file, via my application. automatically..is it possible to resolve this issue!
I need to script to change TTL of all zone file in my DNS and aslo i require the serial to be updated to reduce my work load.
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.

I just wrote an html file, but somewhere on the write I lost count of the paragraphs.
In an html file paragaphs starts with <p> and ends with </p>
What I want to know is how to find the valid paragraph.
I used grep '<p>' file_name | grep -wc '</p>' . I dont know if this works.
So this is my code:

Modification of code I found here. It works, but I don't really know why.
Q1: Why is each filter hit counted only when the conditional is not true?
Q2: I've tried taking the file type, (.old), and put it into a variable for better usability, but then the script fails.

I am trying to match a file consisting of words to many separate other wordfiles in a specific directory. one by one.
What i want the script to do is to report how many matching words my main file has with every file in the directory, each in turn

Each of em are plain text files with 1 word per line
Output should be something like:

View 1 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 would like to use the command line to compare two directories against each other. I have two folders called music collection that have evolved over the last year on two separate computers. 90% of the two folders are the same, but there are small differences. I would like a solution that will print out all the differences so I can analyze them and choose what I want to do with them, before merging the two folders. for example.I would like some kind of output that shows the differences and where its located.
comparing MusicCollection1 and MusicCollection2
dif1.mp3 located in MC1/folder1 (this one I might want to keep and merge over)
dif2.mp3 located in MC2/folder3 (while this one I might realize does not exist in both folders because I deleted it for a reason)
I've looked at sort, uniq, and even tried scripting my own solution, but haven't come up with an elegant solution thus far. Its important that it is recursive because there are about 15 folders in Music collection and more folders under those 15.
I'm trying to write a script that takes two arguments, the first argument is a number, and the second argument is a filename. The shell script should indicate if the file's size is BIGGER or SMALLER the number provided. this is what i have sofar, am i on the write track, i'm hoping its just a problem with my if command
if [ $1 -h $2 ]

Im trying to compare two files and I only want to display the user names that are in the first file and not the second.
So I have one file named final.txt (which contains every user name and only the user names in a list no other information)
Then I have another file Over1.txt (which only contains certain users that have different permissions This file is also setup differently with the user name and some information about the user after the user name.
I need a way to compare final.txt to over1.txt so that I will only display the names that are in final.txt but not Over1.txt
Ive tried using diff and comm but just cant seem to get it two work correctly. Im not sure if im missing a option or what.
Im using an if statement in the bin ash shell and it isnt working.
Code: if (( 5000 > $available_blocks )) then echo "WARNING Disk space low, "$pct_used" is used" fi
I don't think its a problem with the if. When i use that code it creates a file with name of the value $available_blocks instead of using the '>' sign for comparing the 2 numbers.

View 13 Replies View RelatedThe thing is, I've created a new local zone here (called "local.lan"), and, aparently, it is working fine, and DHCP3-SERVER is updating DNS info through the controls.But sometimes I get some strange answers from the server, like when I do the "arp" command in one of the clients, and get the server's hostname "mixed" with it's own reverse, like this: "dns.local.lan.2.168. | ether | 00:02:1e:f5:61:74 | C | eth0". Other thing is that sometimes my DNS don't update when a computer "enters" the lan. In the /var/log/syslog the DHCPOFFER appears, but the information about the DNS update isn't there.So, I would like to show you my named.conf file and my local zone db file, and get some feedback from you (what would you change... what is wrong...).

how to configure reverse zone for x.x.x.x/18 subnet ,all the example on the internet are for /24 or /16 subnets?
View 9 Replies View RelatedI have a DNS server with 3 zonesone is dynamic with an associated reverse and one is static
Everything was fine until I added a single host in the staticzone then the server stopped resolving names in that zoneThe only way I could get it to work again was delete the whole zone and re enter the zone and hosts
I have a server which time zone is in GMT format. I have a user which is also get time zone variable in GMT. But I want to run script which will start from crontab in EST time zone. For that I�m not suppose to give extra entry in crontab. May be it would be in script.
How can I achieve this?
It's possible to configure a second level zone like this:
IN CNAME www.domain2.ext
For example, if I want:
host domain1.ext -> CNAME of www.domain2.ext?
and NOT only www.domain1.ext -> CNAME of www.domain2.ext?
We have a 10.0.0.x network with a working DNS Server (BIND) setup. Recently we purchased Watchguard firewall and configured three networks, so that our internal network can be divided into three networks and talk to each other through firewall routing. So I configured three ips 192.168.0.1,172.16.0.1 and 10.0.0.1 for local network card in the firewall router. I separated three networks and individually configured machines with static ip and given gateway as the above ips. Now, I need to configure DNS server for each zone in the same server which is in the network 10.0.0.x, is this possible?. If yes do I need to setup ip aliases for eth0 in the DNS server with different ips from each network?
View 1 Replies View RelatedI'm having this problem that's driving me nuts.Basically I've set up 2 virtual DNS servers.1. Master on fictive domain "domain.xx". 2.ster of fictive domain "sub.domain.xx"NS 1 delegated sub. zone-space to the DNS 2.Everything works except for reverse lookup on sub-domain.For instance. 172.16.0.101 should resolve to my fictive mail.sub.domain.xxIf I try to resolve it with 'host 172.16.0.101' from domain.xx I get:Host 101.0.16.172.in-addr.arpa not found: 2(SERVFAIL)If I do the same from the actual sub.domain.xx I get:Host 101.0.16.172.in-addr.arpa. not found: 3(NXDOMAIN).
If I, on the other hand, try to resolve a hostname both from domain.xx or sub.domain.xx with 'host mail.sub.domain.xx' I get the proper address as the answer: 172.16.0.101I've delegated the in-addr.arpa space to sub.domain.xx dns-server according to RFC 2317 specification, at least I think...Please note this is a virtual network address 172.16.0.0/24Here are the excerpts of the in-arpa-files on both domain.xx and the sub.domain.xx server.
Code:
$TTL 12h
$ORIGIN 0.16.172.IN-ADDR.ARPA.

Here's a little tool that does this:
Without arguments, updates the SOA serial in a zonefile to the current date. If the date was already updated, just updates the revision number (incrementing up to 99, and then again 01). Uses RFC 1912* recommended format.
With $1 == <two digit number>, auto updates (if necessary) just the date part and uses your provided revision number.
With $1 == <eight digit number>, uses that as a date (no validation of any kind), and just auto update the revision number
With $1 == <full serial>, will just replace whatever the serial is with the provided serial, without any validation
* YYYYMMDDRR (4-digit year, 2-digit month, 2-digit day of month, 2-digit revision number)
This script + keeping SOA/NS/MX/CNAME RRs in a common file $included from other files with $ORIGIN and A/PTR/TXT RRs, made everything way easier to manage, enabling me to script some zone switchers, automatic failover/redirection of DNS on WAN changes, etc, etc. I think this stuff might be cool to integrate with something like this script and make nice CLI toolset for bind. Looking forward to implement it.

I have configured master and slave Bind servers. Everything works fine. But whenever I add a new zone entry at master server it is not getting updated at slave server in logs I see this error:
client 192.168.1.1#43428: view external: received notify for zone 'yourdomainname.com': not authoritative
At master server I do not see any error or warning message. This error clearly indicates that named.conf file does not have zone entry in it or domain name is wrong. While checking the named.conf file I see that the zone entry has not been updated at slave server. If I update it manually and reload named on slave then zone files (db files) are getting created without any issue and any modification at master server for the zone records are also getting updated. My concern is why zone record is not getting appended at slave server in named.conf file.
Is there anything I am missing in the configuration. I am pasting the steps which I have followed to configure my master and slave server:
Configure Bind as master and slave server
Install Bind on your server
yum install bind
OR
sudu apt-get install bind9
Generate RNDC Key using the command
rndc-confgen -a -k rndc-key
it will stored in /etc/rndc-key file
Master Server IP 192.168.0.1
Slave Server IP 192.168.1.1
