I seem to have an IP address stuck and can't clear it... Is there anyway to force Gargoyle to clear it's cache?

Find the process number of dnsmasq on your router and type 'kill -s SIGHUP <pid>"

But often such problems are due to the client machines cache and not the router's.

As it turns out it's my ISP's name server... seems just about every lookup I do shows the correct IP except when I use the default auto ISP supplied one... :(

Hopefully that will update shortly and solve my problems.

ere are often problems with the DNS servers of the ISPs (at least here in Denmark).
I am using the following (google and opendns)...
8.8.8.8
8.8.4.4
208.67.222.222
208.67.220.220

Easiest way to do this on both Gargoyle and any version of OpenWRT:

SSH into the router & restart dnsmasq

Code: Select all

./etc/init.d/dnsmasq restart
Cache cleared! (At least at the router, doesn't mean the isp hasn't cached it too!)

Hope this helps anybody that wants to do this in the future.
