The reverse DNS PTR record for IPv6 address 2001:468:616:820::20 would look like this: 0.2.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.2.8.0.6.1.6.0.8.6.4.0.1.0.0.2.ip6.arpa. 3600 IN PTR sinclair.wpi.edu. > Likewise, I'm not sure about how DHCP would be configured, if I have > to touch it at all. You don't need DHCPv6 unless you want to control the assignments, do dynamic DNS, etc. such as in a managed network environment. You can instead use SLAAC (Stateless Address Auto-Configuration) which is built-in to every IPv6 host and doesn't require any kind of server. You only need a Router Advertisement service to inform the hosts of the router(s) and global prefix(es) available on the link. You can run radvd on the router to provide this: yum install radvd

Here's an example reverse record for IPv6 address 2001:468:616:820::20: 0.2.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.2.8.0.6.1.6.0.8.6.4.0.1.0.0.2.ip6.arpa. 3600 IN PTR sinclair.wpi.edu. DHCPv6 is supported by ISC DHCP. You have to run a separate service (dhcpd -6) since the server only supports one protocol at a time. However, DHCPv6 isn't required to assign v6 addresses. DHCPv6 is only really required if you want control over the assignments such as in a managed network environment. You can instead use SLAAC (Stateless Address Auto-Configuration). This is automatic--no server required. You can run radvd on the router to announce the availablility of the router and global prefix(es) available on the link. yum install radvd

IPv6 config question

by William Smith

Hiya! I've got an old laptop (Sony Vaio PCG-F520) that I've been setting to re-purposing. To this end, I've installed Fedora 10 on it. I've got DNS (IPv4) and DHCP configured on it, and it will eventually be acting as a printserver for an HP LaserJet 4MP. :) My question is this: How difficult (or involved) would it be to add IPv6 support to this? I know about AAAA records, but I'm not so sure what the reverse lookup file would look like. Likewise, I'm not sure about how DHCP would be configured, if I have to touch it at all. Any suggestions would be appreciated. -- Bill Smith Fall River, MA Charter Member of LOPSA

Hi Group, We found the drive described in the subject line at work, and have no use for it. It appears to be new. Anyone have fibre channel, and want it? -Jamie

Looking for DDR400 (PC3200) RAM

by John Stoffel

Guys, I'm trying to ressurect an old MSI K8T NEO mother board with an Athlon64 3000 CPU. Unfortunately, I don't have any 184 Pin PC3200/DDR400, PC2700/DDR333, PC2100/ DDR266 or PC1600/DDR200 unbuffered DIMM boards. Probably 512Mb each (I've got three slots), though bigger is always better, right? I'd be willing to travel in the worcester area tomorrow to do a pickup, or hit a store with some if anyone has any suggestions other than the guys in Northboro on Rt 20. Thanks, John
