I used this guide
to set up IPv6 tunelling in Ubuntu 8.04 and it works fine.
Flushed with this success, I installed tspc from source in Foresight Linux (not available in Foresight repos) and this also seemed to go fine in that running "ifconfig tun" gives the expected output.
However, ping6 (installed through iputils) doesn't work as it should.
Whereas in Ubuntu, I can ping6 to ipv6.google.com or to broker.freenet6.net without any problems, when I try ping6 in Foresight to the same ipv6 sites, I get this error:
can't receive hop limit: Protocol not available
Note that both /bin/ping and /bin/ping6 are available in Foresight, just as they are in Ubuntu. But while both ping and ping6 work in Ubuntu, only ping, but NOT ping6, work in Foresight.
Anybody know what might be the problem here?
