It's amazing what you discover whilst working a weekend shift with a bit of time to spare. Whilst perusing through the shell scripts used as part of the Sun in-house built VPN solution (Oracle are giving it the chop in favour of Cisco SSL AnyConnect client which doesn't officially work on Solaris x86 - it does with the help of openconnect though ;-) ), I discovered a little easter egg in ping(1M). Fire up a terminal and ping a host: $ ping google.com google.com is alive $ Nothing fancy there and exactly as I expected. However, if you're a Linux/Mac... Continue reading ►

Is it just me or has NWAM lost the "M", ie the magic, in snv_135? I've recently updated and whilst the NWAM functionality has apparently been enhanced (there's way more configuration stuff now) and a more functional GUI implemented, for the life of me I can't get it to reliably connect to my home wifi network. I need to poke and prod it to come to life on each boot. Time to go digging to see if I can work out why. Update: This has now been resolved in snv_138 - it was a problem with the WPA svc not...

Links of interest for 28 Aug 2009 - 1 Sep 2009: Apache.org Compromised via stolen SSH keys - Best bit: "... we restored from a ZFS snapshot to a version of all our websites before any accounts were compromised." Now how's that for an advertisement for Solaris and ZFS? Oracle is likely to sell sun's hardware business to hp - The Inquirer - [Updated: My initial comments here have been removed as I may give people the idea that I actually have insider info on this. I DON'T.] New attack cracks common Wi-Fi encryption in a minute - ... Continue reading ►

Links of interest for 6 Jan 2009 - 29 Jan 2009: iWeb acquires the Sun Storage 7410 for its storage area network - It#039;s nice to see companies starting to promote the fact they#039;ve switched from a proprietary storage system to the Sun Storage 7000 range. Understanding ZFS: Disk Space Discrepancies - I#039;ve seen this discrepency before, but haven#039;t had the time to research it. Thanks to Ben, I don#039;t have to. Definitely worth remember this one. IPMP Re-architecture is delivered - A great introduction to the re-architected IPMP including examples of the old and new configuration styles. Once OpenSolaris...

Just a quick heads up - Sun has issued a Security Alert about a vulnerability in IPv6 in Solaris 10 and OpenSolaris builds 101 - 107: SunAlert: 251006 Title: A Security Vulnerability in Solaris IPv6 Implementation (ip6(7p)) May Cause a System Panic An insufficient validation security vulnerability in the Solaris IPv6 implementation (ip6(7p)) may allow a remote privileged user to panic the system using a crafted packet. This is a type of Denial of Service (DoS). An IDR/ISR is available for this issue and is linked to in the SunAlert. If you're in an environment which needs approval before applying ...

I've anxiously been waiting for this update email to say the snv_105 changes are now available for OpenSolaris. Now I can get playing with the cool new Project Crossbow networking functionality as Ben did here and here. I could have played with this when it first came out, except I took the decision to move 100% across to OpenSolaris on my machine at work instead of running the SXDE builds. No more dual boot. Just 100% OpenSolaris.

Links of interest for 1 Jul 2008 - 30 Jul 2008: Direct Mounting of Files - As of snv_91, you no longer need lofi to mount a filesystem image, like an ISO. You can now call mount(1M) as you would a normal filesystem. DTrace IP Provider - Cool. The first step of implementing TCP/IP DTrace providers in Solaris has made it's way into snv_93. OpenSolaris 2008.11 - A Preview For The Storage Admin - A great review of the features you can find in OpenSolaris 2008.11 from a Storage perspective, ie the stuff sysadmins want, but the other reviews never...

Links of interest for 21 Mar 2008 - 25 Mar 2008: Paper Enigma Machine - What a brilliant idea, and a great teaching tool too. Sun turns to lasers to speed up computer chips - Now this would be brilliant if Sun research proves to be a success. Sun's continually proving it is light years (excuse the pun) ahead of everyone else in the processor business and this is just another example. Australian WiMAX pioneer trashes technology as "miserable failure" - I wonder how many more people are going to come forward now and bring their problems to light. All... Continue reading ►

Links of interest for 27 Nov 2007 - 11 Jan 2008: 2008 Technology of the Year Awards: Storage - And the award for Best Filesystem goes to... ZFS, naturally. No other filesystem has been as innovative, with such wide spread adoption, recently. Official ZFS on OS X Page - Your source for bleeding edge ZFS on OS X from one of the ZFS developers at Apple. 2008 Technology of the Year Awards: Platforms - And the award for the Most Innovative Server OS goes to... well, Solaris 10 of course. Who else? shimmer - A great alternative to port knocking,... Continue reading ►

Following the most recent data loss by HMRC, they and other companies should seriously start considering dumping laptops in favour of Sun's Sunray technology for their "Work from home" users, and maybe even all of their normal desktop users. For those who don't know, Sunray is a secure, truly stateless device that effectively presents a working desktop environment to a user over the network and consumes very little power. Think of a mix between the ease and simplicity of the old green and black dumb-terminals and the full functionality of your normal desktop and a whole lot more. Continue reading ►
