My Solaris box is running IPv4 and IPv6, but my linux box is not... it's only running IPv4... so i want to enable it! I swear it used to be running... but that could have been on my old linux box...

Anyway, here's my current ifconfig for turnip (the debian box):

CODE

turnip:/home/hobbs# ifconfig -a eth0      Link encap:Ethernet  HWaddr 00:50:BA:62:AE:19            inet addr:192.168.254.101  Bcast:192.168.254.255  Mask:255.255.255.0          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1          RX packets:28632841 errors:239 dropped:3166 overruns:227 frame:0          TX packets:33992980 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:100          RX bytes:1726041674 (1.6 GiB)  TX bytes:2605368187 (2.4 GiB)          Interrupt:9 Base address:0xac00 lo        Link encap:Local Loopback            inet addr:127.0.0.1  Mask:255.0.0.0          UP LOOPBACK RUNNING  MTU:16436  Metric:1          RX packets:1565021 errors:0 dropped:0 overruns:0 frame:0          TX packets:1565021 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:0          RX bytes:622236990 (593.4 MiB)  TX bytes:622236990 (593.4 MiB) turnip:/home/hobbs#

so as you can see... IPv6 is not enable, although i know support for it is possible.

How do i enable it?? It's working fine on Solaris:

CODE

bash-2.05# ifconfig -a lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1        inet 127.0.0.1 netmask ff000000 hme0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2        inet 192.168.254.100 netmask ffffff00 broadcast 192.168.254.255        ether 8:0:20:81:19:ac lo0: flags=2000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv6> mtu 8252 index 1        inet6 ::1/128 hme0: flags=2000841<UP,RUNNING,MULTICAST,IPv6> mtu 1500 index 2        ether 8:0:20:81:19:ac        inet6 fe80::a00:20ff:fe81:19ac/10 bash-2.05#

SO:
- turnip (debian): 192.168.254.101
- eMonster (Solaris): 192.168.254.100 and fe80::a00:20ff:fe81:19ac

add the ipV6 modules (or have it compiled in the kernel)
you should get somting like this :-

im my case it is just there (unconfigured but there)
one warning though having read a very little of the linux ipv6 howto (yes you should read this, and asking how to enable ipv6 is probably a silly question as I posted a link to the ldp a while back :P ), it seem that the implementation of ipv6 in 2.4 is a bit broken (incorrectly implemented at least) this should be fixed in 2.5 and the next stable branch 2.6
(odd numbered linux kernel series are where all the hard development and feture addition goes on, the even ones are the stable products of this)

thanks for the info..... i'm using the bf2.4 kernel unfortunately, and i can't be bothered to reinstall it, so i'm gonna use my Solaris machine instead until i move house again in about 5 months (which will give me an opportunity to use a different kernel, hopefully 2.6).

I would just try modprobe ipv6 and see if the Debian box likes that. Your lsmod and ifconfig should look different if it works.
