Problem running dnscache
According to the instructions at http://ezine.daemonnews.org/200210/ezdjbdns.html and http://forums.devshed.com/showpost....629&postcount=6 I did the following:

Code:
charles@web[0]~$ sudo mkdir /var/djb
charles@web[0]~$ sudo dnscache-conf dnscache dnslog /var/djb/dnscache 192.168.0.53
charles@web[0]~$ sudo touch /var/djb/dnscache/root/ip/192.168.0
charles@web[0]~$ sudo ln -s /var/djb/dnscache /var/service
charles@web[0]~$ sudo svc -t /var/service/dnscache
svc: warning: unable to control /var/service/dnscache: file does not exist


Why do I get that error message?

What does 'ls -ld /var/service/*' say?

0 lrwxr-xr-x  1 root  wheel  17 Mar 22 20:29 /var/service/dnscache@ -> /var/djb/dnscache


According to freebsd's instructions on http://forums.devshed.com/showpost....62&postcount=11 I also tried this:

Code:
charles@web[0]/var/djb/dnscache/root/ip$ sudo svc -d /var/service/dnscache/log
svc: warning: unable to control /var/service/dnscache/log: file does not exist


Driving me nuts...

And the content of @ is as per freebsd's suggestion (didn't have to change it).

He also said that dnscache/root/ip should contain exactly the one file, while the instructions on http://cr.yp.to/djbdns/run-cache-x.html say:

Quote:
6. As root, create entries in /etc/dnscache/root/ip showing which client IP addresses are authorized to use this cache. For example,

touch /etc/dnscache/root/ip/10

authorizes all clients with IP address 10.* to use this cache. You can add or remove addresses later.


You know why he advised otherwise? Maybe the other person didn't need the cache to be able to be accessed by his private network?

It's working!
svscan wasn't running. Found this at http://ezine.daemonnews.org/200210/...s.html#appendix

Had a hard time figuring out how to start /usr/local/etc/rc.d/svscan.sh, but figured it out. I tried running ./svscan.sh from it's directory, but that didn't work. I had to start it with it's full path like so: /usr/local/etc/rc.d/svcscan.sh. This way, the regex in the file can determine the PREFIX.

Now, let's see if dnscache works as expected....

Everything works and dnscache is doing it's thing on 192.168.0.53. Next step: tinydns on 192.168.0.1 .

* SilentRage vaguely approves the use of dnscache but grinds his teeth over tinydns
