I guess it would depend on how they're blocking it. On my home setup I have the following configuration:
The 209.* forwarders are the DNS servers for my ISP. The net effect is that a query for any zone for which it doesn't consider itself authoritative for (trunkator.com and it's reverse zone) it will forward to my ISP's DNS servers. The DNS requests to the ISP is identical to the type they would have to be supporting anyways so they don't have any criteria by which to differentiate the traffic.
Hi all,
I've 2 Debian Etch (4) box used as ns1 and ns2 with BIND9. My domain name is something like this:
subdomain.domain.com
And I've 2 authorized DNS servers for the subdomain. I set this line in both of ns1 and ns2 (I.e. in ns1.subdomain.domain.com and ns2.subdomain.domain.com):

I have problems with a simple BIND configuration in CentOS. I have a static public IP 1.1.1.1 and I recently bought a domain name gigi.com. I just want that gigi.com points to 1.1.1.1 (Apache Web Server).
This is how my named.conf file looks:

When you get the message can't bind to ip already in use.
is there a command to search to see everything that is using that IP?
I've already check the host and hostname files (2 Replies)

bup-margin
bup-margin(1) General Commands Manual bup-margin(1)NAME
bup-margin - figure out your deduplication safety margin
SYNOPSIS
bup margin [options...]
DESCRIPTION
bup margin iterates through all objects in your bup repository, calculating the largest number of prefix bits shared between any two
entries. This number, n, identifies the longest subset of SHA-1 you could use and still encounter a collision between your object ids.
For example, one system that was tested had a collection of 11 million objects (70 GB), and bup margin returned 45. That means a 46-bit
hash would be sufficient to avoid all collisions among that set of objects; each object in that repository could be uniquely identified by
its first 46 bits.
The number of bits needed seems to increase by about 1 or 2 for every doubling of the number of objects. Since SHA-1 hashes have 160 bits,
that leaves 115 bits of margin. Of course, because SHA-1 hashes are essentially random, it's theoretically possible to use many more bits
with far fewer objects.
If you're paranoid about the possibility of SHA-1 collisions, you can monitor your repository by running bup margin occasionally to see if
you're getting dangerously close to 160 bits.
OPTIONS --predict
Guess the offset into each index file where a particular object will appear, and report the maximum deviation of the correct answer
from the guess. This is potentially useful for tuning an interpolation search algorithm.
--ignore-midx
don't use .midx files, use only .idx files. This is only really useful when used with --predict.
EXAMPLE
$ bup margin
Reading indexes: 100.00% (1612581/1612581), done.
40
40 matching prefix bits
1.94 bits per doubling
120 bits (61.86 doublings) remaining
4.19338e+18 times larger is possible
Everyone on earth could have 625878182 data sets
like yours, all in one repository, and we would
expect 1 object collision.
$ bup margin --predict
PackIdxList: using 1 index.
Reading indexes: 100.00% (1612581/1612581), done.
