RE: [PLUG] bind9 not allowing WinXp clients to update DDNS
|
I don't know why your zone files are in /etc/bind --double check
named.conf
You needn't create the .jnl files manually, they're created and
updated by named. Wherever this is writing, the directory must
have write permission by the named process. Chances are, this is
running as username named.
