What is wrong? "Creating metasocket failed"

[Bert Jan Bakker]

Hi there,

I'm trying to set tinc and I get the following messages:

Sep  6 13:31:33 leibniz tinc.acvpn[12352]: tincd 1.0.1 (Aug 14 2003 15:09:44) starting, debug level 0
Sep  6 13:31:33 leibniz tinc.acvpn[12352]: /dev/net/tun is a Linux tun/tap device (tun mode)
Sep  6 13:31:33 leibniz tinc.acvpn[12352]: Script tinc-up exited with non-zero status 126
Sep  6 13:31:33 leibniz tinc.acvpn[12352]: Creating metasocket failed: Address family not supported by protocol
Sep  6 13:31:33 leibniz tinc.acvpn[12352]: Ready

My kernel is 2.4.20-686-smp from a debian kernel-image package.
The version of tinc is 1.0.1-1.

A few questions:
- does the failure to create a metasocket mean tinc won't work? The
  last message, "Ready", seems to indicate there's no problem
- I'm a bit confused about working with devfs. I noticed that loading
  the tun module causes the /dev/net/tun to be created. I assume devfsd
  does this for me. Is that right?
- Is it necessary to let tinc load the tun module or does it depend it
  the tun module to be already loaded?
- If tinc can take care of loading the tun module, how do I set this up?   Is the "alias char-major-10-200 tun" entry in the /etc/modules.conf
  enough?
- I'm trying to create a connection from home to the office.
  Unfortunately my home cable router maps the 655 port to an
  unpriviledged port when it does outgoing NAT. So I cannot initiate the
  connection from home. My idea as a workaround is to log in to
  the office firewall running tinc by ssh and do a ping to my home
  host. The home cable router is configured to redirect the incoming
  traffic on the tinc port to my home workstation. Will this work?
