Wifidog reported the node down, but I was able to connect to it through the VPN. Wifidog was running, but DNS wasn't resolving. I edited /etc/init.d/S50dnsmasq and changed the line that read “nameserver 127.0.0.1” to “nameserver 184.108.40.206” and then added another line below it, “nameserver 220.127.116.11”. (Those are opendns servers.) I then edited /etc/resolv.conf with those same two lines, and it started working right away.
Exactly the same problem as Nov 29 2009. The DNS servers were still in the lan_dns value in nvram, but weren't in the /etc/resolv.conf. I added them, and the router was then able to resolve DNS addresses.
Wifidog reported that it went down 3 days ago. I connected via VPN. Wifidog was still running ('wdctl status'), but was reporting that it couldn't connect to the auth server. I tried pinging the auth server ('ping auth.wirelesstoronto.ca') and it couldn't resolve the address. I changed the DNS server in both /etc/resolv.conf ('vi /etc/resolv.conf') and in the router config ('nvram set lan_dns='18.104.22.168 22.214.171.124') and it started working.
Installed by Gabe. Channel 1. It's in the office. WAN port of the wireless router is plugged into a D-Link wired router which is in turn plugged into their 'net connection.
