Hi list,
here is what happened:
today I noticed some resolution's problems on my network. I did a
"service named status" and here was the output:
# /etc/init.d/named status
rndc: connection to remote host closed
This may indicate that the remote server is using an older version of
the command protocol, this host is not authorized to connect,
or the key is invalid.
In the named's log, several entries like that:
general: error: invalid command from 127.0.0.1#42033: bad auth
I am not using the key's authentication on my chrooted bind dns and it
was working great so far.
Searching on rndc's files in /etc I've found mismatch for the key value
in /etc/rndc.conf and /etc/rndc.key. There was also a rndc.key.rpmnew file.
After giving the good value for the key entry (I've copied-pasted the
value from the .key file), the bind daemon seems to be happy now.
My question is how things get broken because I didn't touch the bind's
config files for a year or so (only the zone files, sometime) ?
