If thin clients like the SunRays I’ve shown in BIVBlog #34 were so appealing to users, system administrators and managers alike, then why did they stay a niche product? And why does nobody care about them anymore? The answers to these questions are interesting not only with regard to thin clients, or SunRays, but to […]
During an IPv6 training I held last year I was given two Sun Microsystems SunRay 1 thin clients. I give them a closer look, explain why they caused so much excitement when they hit the market, and tell about the problems I ran into trying while trying to get the server side to work.
Filtering ICMP packets for IPv6 (or ICMPv6, or ICMP6, depending on the texts you read) is somewhat daunting at first. But once you’ve thrown your fears and possibly dogmatic attitude towards ICMP out the window, setting up a reasonable packet filter configuration is actually fairly straightforward. This video is basically a translated re-run of a […]
Here are my personal highlights from last week’s RIPE-68 in Warsaw/Poland, and some quick info on a secret little project of mine.
In a reply to the previous episode, Matthias pointed out that while the ramond is a useful tool, it is little if any use against a malicious attacker. Right, but if you let an attacker into a subnet with potential targets, you are in some very serious trouble anyway.
As promised in episode #22, here are some simple but useful things you can do with IPv6 Autoconfiguration but can’t do with DHCP.
In virtually all IPv6 trainings and consulting sessions the question pops up if DHCPv6 or Stateless Address Autoconfiguration (SLAAC) is the way to go. Here’s why you quite likely need both.
If you think that IPv6 is a “network job”, you are in for a nasty surprise: The fun really only starts once the network provides IPv6 and you have to make your applications IPv6-aware. And even that’s not primarily a technical job…
If you plan to wait for IPv6 to become “necessary” and then deploy it only on your external interfaces, usually your mail and web servers, you are likely in for a whole range of nasty surprises.
This final episode of the diskless network rescue/install system takes a look at how to customize newly installed systems on first reboot—and the surprises I’ve run into while trying to resize partitions and file systems to make use of the entire physical disk installed to.
