Talk:BIND, dynamic DNS

Revision as of 22:59, 19 August 2008

in set-ddns.pl:

$KEYFILE should probably point to the key file, not the private file.

$KEYFILE = 'Kclient.server.net.+157+15661.private'; should read $KEYFILE = 'Kclient.server.net.+157+15661.key';

par non, complimenteré?

nope. see man nsupdate

nsupdate uses the -y or -k option (with an HMAC-MD5 key) to provide the
shared secret needed to generate a TSIG record for authenticating
Dynamic DNS update requests. These options are mutually exclusive. With
the -k option, nsupdate reads the shared secret from the file keyfile,
whose name is of the form K{name}.+157.+{random}.private.

Kinda confusing, I know, but I'm not the one who made the confusion. (Note how the manpage itself refers to the file as "keyfile" in the argument examples; I'm just following the existing conventions by naming my own variable $KEYFILE.)

Reading on in the manpage:

For historical reasons, the file K{name}.+157.+{random}.key must also be
present. 

So, there ya have it. =)
