The first annual OpenSolaris Storage Summit is coming on Sunday, September 21st, to San Jose, to be followed by SNIA's Storage Developer Conference. This is really exciting. SNIA SDC is one of the best storage conferences in the world (along with USENIX FAST), and OpenSolaris is undoubtedly the more powerful storage platform on earth... this is an excellent opportunity to get a lot of excellent and rewarding information in a week and get ...
Some time ago I wrote a big blog entry entitled Simplifying Zone Management with Kerberos. Since that time (3 years ago!?!) several improvements and simplifications have come along to make life far more pleasant. If your new to Kerberos, please refer to my previous entry before proceeding with this one. Kerberos is still something I struggle to really wrap my head around. Thats probably due to the fact that I have never used it in a ...
Today is everyones favorite day of the year: SysAdmin Day! To all my fellow admins, from myself and Joyent, a very warm pat on the back and "thank you" for all that hard work that no one else acknowledges. So kick back, enjoy a cold pint, and bask in the glory that is UNIX Systems Administration!
This is very important, WarGames, the most important geek film ever made, is in theaters TONIGHT at 7:30pm. ONE SHOWING ONLY. This film has been hugely influential for me, and many others. That awesome unbuttoned shirt over tshirt look that we emulate to this day, decades of trying to get text-to-voice to sound like the film (which was an actor reading the lines word by word in reverse), and who didn't fall in love with Ally Sheedy!...
Recently introduced (snv_92) is the first piece of the DTrace Network Providers, the DTrace IP Provider. Here is a taste: root@ultra include$ dtrace -qn 'ip:ip:*:receive{ printf("Packet recieved from %s: %d byte packetn", args[2]->ip_saddr, args[4]->ipv4_length ); }' Packet recieved from 74.125.15.85: 40 byte packet Packet recieved from 74.125.15.85: 40 byte packet Packet recieved from 8.11.47.20: 88 byte packet Packet recieved from ...
In this entry we'll build on our our IPsec Basics discussed last time and actually create an IPsec connection. IPsec can be used for direct system-to-system access known as "transport mode" or to create a virtual pipeline into which everything is encrypted, known as "tunnel mode". We're going to look at transport mode, which is an excellent solution for encrypting otherwise unencrypted protocols, such as SNMPv1/2 or telnet. When ...
IPsec is a technology widely known. Created for IPv6 and backported to IPv4, it adds a security layer into the IP stack. Prior to IPsec we needed to encrypt data before sending it down the stack and then decrypt it on the other side once it came back out using technologies like SSH or SSL/TLS. IPsec simplifies this by transparently handling encrypt/decrypt as well as header authentication. But for all its intended simplicity and ...
I commonly refer to my faith in blogs and writing but never directly spoken regarding it. This is largely because there have been very few good resources out there for Christians, at least that I was aware of, to actually refer people to, and I don't like leaving people hanging. I'm always happy to have a "Tell me about Jesus" discussion with people interested, but I realize a lot of people are jaded when it comes to Christianity due to "bad ...
Cuddletech Labs has been slowed to a crawl lately as we move from Fremont to Tracy to our new home. For those who are interested, here's a personal update... Nova is 4, Glenn is 2 going on 3 in July, and Tamarah and I are blessed with our third child on the way (current names are Conrad or Eve, depending on gender). The house in Fremont is a rental, we moved to it from an apartment in Fremont just before Nova was born. We're moving because ...
My Moto RAZR was recently lost/stolen (I left it on a table in a resturaunt, 5 minutes later it was no where to be found and a call suggested the SIM card was yanked), but I haven't really dispaired. I've been very interested in iPhone 2.0 but needed clarification on what features it would have, namely I want 3G, GPS, and a better camera. This leak found on CrunchGear suggests that it'll be even better than that! Apparently the iPhone will ...
