The most simple suite for getting started with IPv6 under Linux is probably the Router Advertisement server suite, called radvd<\/a>. Configuration is quite simple, as the radvd.conf only needs a few lines:<\/p>\n

interface eth0
\n{
\nAdvSendAdvert on;
\nIgnoreIfMissing on;
\nMinRtrAdvInterval 30;
\nMaxRtrAdvInterval 100;
\nAdvDefaultPreference low;
\nAdvHomeAgentFlag off;
\nprefix Put:in:your:IPv6:prefix:here::\/64
\n{
\nAdvOnLink on;
\nAdvAutonomous on;
\nAdvRouterAddr on;
\n};
\n};<\/code><\/p>\n

Afterwards (re)start the radvd and you’re good to go. You will notice IPv6-capable machines automatically acquiring addresses starting with the prefix you have set in the radvd.conf. For testing IPv6 connectivity, try ‘ping ipv6.google.com’ or under Linux: ‘ping6 ipv6.google.com’.<\/p>\n

If you are experiencing problems with certain IPv6 sites not working, despite seeing a successful TCP connection, you might be experiencing the so-called ‘Path MTU problem<\/a>‘. A dirty work-around for this problem is adding the configuration line ‘AdvLinkMTU 1280’ to the radvd.conf posted above and restarting radvd.<\/p>\n","protected":false},"excerpt":{"rendered":"
