Linux
There are a number of different Linux distributions on the market, all based on the same kernel, identified by its version number. The Linux kernel has supported IPv6 since version 2.2.x.
In my test network, I used the SuSE distribution of Linux. I liked the user-friendly installation, and the engineers at SuSE were very supportive in getting me started with the IPv6 issues.
Tip
Find more information about the Linux standard and the different available implementations at http://www.linuxbase.org. For an IPv6-specific Linux site, refer to http://www.linux-ipv6.org.
Where to Get Linux
Most of the common Linux distributions can be downloaded from the Internet, but they can also be purchased from the sales channels of their respective makers, including CDs and manuals. It is usually advisable to buy a distribution because the download files are rather big (100-500 MB).
Installation
I used SuSE Linux Version 7.2. If you do a standard installation of this version, it will be based on the Linux kernel Version 2.4, and the IPv6 protocol stack will automatically be enabled in addition to the IPv4 stack. The current inet daemon supports IPv6 and is responsible for all networking tasks, such as FTP, telnet, or finger. The configuration file /etc/inetd.conf must be changed for IPv6 support. Consult the inetd man page for more information.
Tip
To find the latest kernel, check with your distributor’s support site.
