Tun0 not coming up / issue with aiccu
![[fr]](/s/countries/fr.gif) Shadow Hawkins on Tuesday, 02 July 2013 13:07:49
I'm trying to setup a tunnel using hearbeat as I don't have a fixed ip.
I'm nated. Running Osx 10.7.5.
I've installed tun/tap and aiccu using brew and it worked (or looked ike it did).
Here is what I get when I try to start aiccu :
oulan:dev ludo$ pwd
/dev
oulan:dev ludo$ sudo aiccu start
Password:
sock_getline() : "200 SixXS TIC Service on nlhaa01.sixxs.net ready (http://www.sixxs.net)"

I have tun0
oulan:dev ludo$ ls tun*
tun0tun10tun12tun14tun2tun4tun6tun8
tun1tun11tun13tun15tun3tun5tun7tun9
but :
oulan:dev ludo$ ifconfig tun0
ifconfig: interface tun0 does not exist
I'm wondering why tun0 isn't showing up. and what I would need to do to be able to get the tunnel up again.

Note these two lines:
sock_getline() : "Type: 6in4-heartbeat" [..]
ifconfig: interface tun0 does not exist
tun0 is typically used by the TUN/TAP driver, this is used for instance for AYIYA but also for other tools like OpenVPN, tinc etc.
Your tunnel type though is "6in4-heartbeat", this requires a 'sit' (Simple Internet Transition) interface.
Check your aiccu.conf, it likely contains a 'ipv6_interface' statement, comment it out or set it to something like 'sixxs' or 'aiccu' instead, and things will magically start working.

Indeed open vpn brings tun0 on when I connect to some vpn for work.

Do you have a link with more information on that.

When I do this I get :

My aiccu config looks like :
# Protocol and server to use for setting up the tunnel (defaults: none)
#protocol <tic|tsp|l2tp>
#server <server to use>
protocol tic
server tic.sixxs.net
#ipv6_interface tun0
tunnel_id T126310
verbose true
daemonize false
automatic true
requiretls false
rest is commented or default.
I don't understand why tun0 doesn't come up.

What magic do I need to create and get the /dev/aiccu interface ?

Nothing, as there is no such device. It is an interface, that is created by the kernel on the fly. It does require that the 6in4 driver called 'sit' is either loaded already or loadable on the fly.
Do a 'lsmod | grep sit' to check if that driver is loaded. Of course you'll also need a functioning IPv6 stack.
Providing more details about your environment can be useful in this thread.

I'm running OSX 10.7.5. Connecting using the en1 network interface.
I should have noticed that from the AICCU output.
As such, add to your aiccu.conf:
ipv6_interface gif0
That should do the trick.

Great, enjoy your connectivity!
As a side-note for googlers: the FAQ (Where can I get the tunnel driver for Windows, Mac OS X and NetBSD?) contains details for getting 'tun0' working on OSX as that needs a separate driver.

See amongst others the 6in4 page on wikipedia.
ifconfig: interface aiccu does not exist
Looks a lot like you are missing some drivers on your host. What platform/distribution is this exactly?
I don't understand why tun0 doesn't come up.
Because it should not come up. Tun0 is TUN/TAP, used for AYIYA. The tunnel you specified is a 6in4-heartbeat tunnel. See the FAQ or the above wikipedia page for some details.
