* gentoo box as rotuer with dnsmasq and iptables.
* gentoo desktop
about 2 weeks ago the isp went down. (does once in a while for upgrades)
i tried to ssh from my desktop to the router and ssh took forever. i was
guessing that it was a time out of something. but didnt think it would
since i ssh tp an ip; ssh 192.168.168.1 from host_name_mattspc (mattspc is
in the name in the lease file) after asking around to why that would time
out, i was told that it was ssh doing a reverse look up and that i can
turn that off. i dont think i need to turn it off. but why would
dnsmasq take that long when the isp is down? dnsmasq is a cache and
should know the ip? dnsmasq gave out that lease, i would expect it to
know that ip. and doenst it always know the ips on its subnet ?
