My npd6 (neighbor proxy daemon IPv6) project has now fully relocated to GitHub: https://github.com/npd6/npd6
All code has been moved, with full branching history, tagging, commits, etc. Fully replicated under git.
Bugs are harder to move, but it’s been done. Unfortunately we lose some info on the way, mainly email information for commenters. Obfuscated […]
On a fairly vanilla install of Ubuntu 12.04 (i.e. current) in an environment with full IPv4 and IPv6 connectivity one may seem some (at first sight) strange things concerning the IPv6 addresses in use.
The network has a single gateway router/server, and provides full IPv6 to the devices in the house using radvd and […]
So what must npd6 do in functional terms?
See Neighbor Solicitations. EITHER respond to them directly OR respond via the existing mechanisms. Log activity. Report status. Receive Neighbor Solicitations
The daemon needs to receive incoming neighbor solcitations from a designated port(s). I currently have no idea if this is an easy hook to make from […]
The scenario: the home network is centered around a Linux server. This acts as (amongst a number of other things) a large data repository. All our media files, photos, music and so on are stored on it. Apart from the convenience of having it all centrally located, it also provides data security: all critical […]
With two young children starting to make increasing use of the Internet, my attention has turned in recent times to the thorny subject of Content Filtering. This posting is actually going to look at a technical approach I settled upon, however one cannot help mentioning, at least in passing, some of the wider issues involved.
Previous articles have detailed various aspects of getting IPv6 running on a home-gateway router. The aim is to migrate as much as possible towards an IPv6-only situation.
Here I cover the steps required to implement a simple point-to-point OpenVPN (SSL) VPN tunnel using PSK over IPv6 infrastructure.
One key element for me is to migrate […]
IPv6 DNS – It works for me….. but it shouldn’t.
When in my IPv6 environment I perform a test ping to, say, Google, it seems to work great:
ping6 ipv6.google.com PING ipv6.google.com(2a00:1450:8006::6a) 56 data bytes 64 bytes from 2a00:1450:8006::6a: icmp_seq=1 ttl=55 time=49.3 ms 64 bytes from 2a00:1450:8006::6a: icmp_seq=2 ttl=55 time=44.6 ms . . .
After three articles, where am I with my venture in to IPv6? What have we really achieved so far? Well, in functional terms, not so very much yet!!
Here I covered a lot of ground, getting basic IPv6 running on a Linux gateway box connected to an ISP providing native IPv6, while […]
Following on from my first tutorial, we have a box set up which has basic IPv6 connectivity. There’s a firewall in place with a simple but sufficient configuration. And we can ping6 from this box to remote IPv6 destinations.
All of this has, so far, made use only of one network interface (in my case […]
Following on from my early success at get IPv6 running, I soon hit a significant issue: firewall logging.
Now this need not be a “blocker” for everyone, but I take my firewall logging duties quite seriously…!
shorewall IPv4 logging
Currently I have IPv4 shorewall configured to log not using the standard syslog mechanism, but […]
