Debian turns 20!

Image
On August 16th, Debian will celebrate its 20th anniversary - quite an amazing achievement. It has been my distro of choice since around 2001 and I can't see changing to anything else anytime soon. Thanks to all the people involved in putting it all together :)

A quick guide to setting up a IPv6 Tunnel using public 6to4 relays under GNU/Linux

Image
Sett ing up a 6to4 tunnel will allow IPv6 (or dualstack) hosts on network s that only have P ublic IPv4 addresses to access sites and services that are available via IPv 6. The main steps are calculating the IPv6 version of your Public IPv4 address ; establishing a 6 to4 tunnel to one of the free I Pv6 relays available; and configuring the local network to route IPv 6 via th e tunnel .

Adding 802.1Q Trunking to Debian GNU/Linux

Here's a quick guide to setting up 802.1Q trunking for VLANs on a Debian GNU/Linux box connected to one or more Cisco Catalyst switches, which could then be used as a cheap router replacement. Configuration on the Debian box: Add 8021q to /etc/modules so 802.1Q support is enabled at startup. To install it immediately: # modprobe 8021q Use vconfig to add the VLANs to the interface you'll be using (if vconfig is missing, run apt-get install vlan ): # vconfig add eth0 2 (In the above, eth0 is the physical interface and 2 is the ID of the VLAN) Give the interface an IP. Choose an address in the range you've set aside for that particular VLAN. In this example, VLAN 2 is using 192.168.2.0/24. # ifconfig eth0.2 192.168.2.201 netmask 255.255.255.0
