how to manually create a 6in4 tunnel

Tue, 17 May 2011 20:46:17 -0400

I’m doing some IPv6 codig for a client and needed to setup a bunch of 6in4 tunnels.

Thre are many ways to do this through distribution init scripts (Debian, Fedora), but I wanted something less permanent and more dynamic for testing.

The procedure can be summarized in these steps:

create a tunnel mytun between local 1.1.1.1 and remote 2.2.2.2

  ip tunnel add mytun mode sit local 1.1.1.1 \
                  remote 2.2.2.2 ttl 64 dev eth0

give the local end an address

  ip addr add dev mytun f8c0::1.1.1.1/64

bring up the tunnel
```
  ip link set dev mytun up
```

shrinking URLs

Fri, 20 Mar 2009 21:42:28 -0400

I wrote a short script to shrink URLs:

    % shorturl http://www.jukie.net/~bart/shorturl
    http://2tu.us/ce8

    % shorturl
    Type in some urls and I'll try to shrink them for you...
    http://www.jukie.net/~bart/shorturl
    http://2tu.us/ce8
    http://www.jukie.net/~bart/20090320214228
    http://2tu.us/ce9

I am doing this as part of my new identi.ca addiction^W usage and extending GregKH’s command line micro blogging tool.

UPDATE: also picked up by @vando for use with mcabber.
