update bind via net::dns
Hello,
I would like to update the bind nameserver via a perl script.
Named is running on the same machine I start the script.
I copied the key from
named.conf
key DHCP_UPDATER {
algorithm HMAC-MD5.SIG-ALG.REG.INT;
secret mykeyishere;
};
inserted it into my script and run it.
I always get
Update error code: REFUSED
Can anyone please tell me what is wrong with this script ?
Thanks
Andreas

use Net::DNS;
$key_name = tsig-key;
$key = 'mykeyishere';
$tsig = Net::DNS::RR-new($key_name TSIG $key);
#$tsig-fudge(60);
$update = new Net::DNS::Update('sb-brixen.it');
$update-push(update = rr_add('testserver.sb-brixen.it A 10.53.4.2'));
$update-sign_tsig($key_name, $key);
$res = new Net::DNS::Resolver;
$reply = $res-send($update);
$reply || die (Update failed: . $res-errorstring);
if ($reply-header-rcode eq NOERROR) {

Re: update bind via net::dns ( NOT resolved )
Hello, I made the following modification to the script $res = new Net::DNS::Resolver(nameservers = [qw(127.0.0.1)]); and now I get Update error code: NOTAUTH. This now looks really like a authorization problem, but, as I wrote, I got the key from named.conf.

Re: paths that work in windows and linux + Umlaute
JWK 5) It is Perl4 code from 8 years ago. that code is an abomination. one quick bug is the GetDir recursive descent sub to get all dirs doesn't check for symlinks so it can easily fall into an infinite recursion. the abuse of undef() is beyond bad nor needed. and as john said, it is perl4 code which means it is about 15 years old. it should never be installed or used anywhere. also it says it is for winblows activestate perl so it would never be easily ported to unix as it assumes \ everywhere for dir separators. also most/all of it is available in portable modules on cpan. it seems to more interested in integrating into some winblows gui toy than doing real work. so if you want to learn good perl code, look at that and see what really BAD perl code is like. especially bad perl4 code. uri Hello, I did not ask because I want to learn perl, but because I need the functionality of this application.

paths that work in windows and linux + Umlaute
Hello,
I have found a nice utility
http://www.novell.com/communities/node/389/adm+file+utilities+2+5
that has two problems:
1) It creates directories and files but it uses the \ backslash so it
does not work on a linux machine.
Is there a constant or a function that give back the right character ( /
for linux, \ for windows console ) ?
2) It does ignore Umlaute ( special german characters )
is there a clean way in perl to convert all the umlaute to ascii
standard characters while reading from a file or as in this case in a
array ?
The script reads in the file once
open(ADMFILE,$admFile);
@all=ADMFILE;
close(ADMFILE);
foreach(@all) {
.
Thanks

Re: Encryption
Hello, I got this steps from http://www.ecuoug.org/papers/OraclePasswordAlgorithm.pdf I'm a bit unclear about step 5, but it should be doable in Perl once you determine the EXACT steps you need to take. Here are some tips to maybe get you through the first four steps. This my be far off from what Oracle needs, but it seems to work for your first 4 steps. Some questions remain, like do you need a salt? What do you use to convert back to plaintext hash? Base64encode? What does ignore parity bits mean? You may want to ask this on http://perlmonks.org, where more saavy encryption and Oracle monks hang out. But make sure you can specify the EXACT steps needed. I'm sure it can be done. To be honest, I would assume that the Oracle designers have made this quite tricky to avoid hacking their passwords. According to the document this is not true. I will try your code later.

Encryption
Hello, I have to calculate a hash of username and password in perl. The calculation should be done this way: 1. Concatenate the username and the password to produce a plaintext string; 2. Convert the plaintext string to uppercase characters; 3. Convert the plaintext string to multi-byte storage format; ASCII characters have the high byte set to 0x00; 4. Encrypt the plaintext string (padded with 0s if necessary to the next even block length) using the DES algorithm in cipher block chaining (CBC) mode with a fixed key value of 0x0123456789ABCDEF; 5. Encrypt the plaintext string again with DES-CBC, but using the last block of the output of the previous step (ignoring parity bits) as the encryption key. The last block of the output is converted into a printable string to produce the password hash value. Is it possible to implement this in perl ? Is the Crypt-DES Module on CPAN the right module and how can I convert standard string to Multibyte storage ( UTF-16 ? ) An example ist User: example password: test hash: BDA63848A8C31752 I don't need this script to hack anything, we would like to modify oru oracle paasword from a webfrontend.
