I've been having trouble with ipv6 going down frequently with comcast these days. They're working on the problem but my Debian box is down when this happens. Is there an easy way to switch the box to ipv4?
After installing Debian stable (squeeze) I found that eth0 is not coming up, when I bring it up with "ifconfig eth0 up" only IPv6 is configured. Installation did happen in a home network with IPv6 enabled through a tunnel and a radvd router. Which makes me think it may have decided to disable IPv4, don't know how or why.
