Fwd: Open Position @ Brown
by Phillip Deneault Dec. 5, 2013

Dec. 5, 2013

Brown University is looking for a security-centric Windows/Linux admin for a special environment they are building to process health care records. If you have experience with security regulations and technologies and like the straight-shot commute to Brown via 146 rather than commute to Boston on the Pike, this might be for you. Please respond to the position description and not to me. I do not represent Brown or know anything about the job beyond what is here, I'm just posting for a friend. Thanks, Phil

Meeting next week ?
by Henrique Dec. 4, 2013

Dec. 4, 2013

Hey Linux Enthusiasts, Are we having a meeting next week? There are plenty of interesting stuff going on lately: Valve, one of the major distributors of games for PC is moving towards Linux, and just joined the Linux Foundation - http://thenextweb.com/insider/2013/12/04/valve-joins-linux-foundation-prepa… - This is also pushing AMD/Nvidia to push for better graphics drivers. Interesting bits from Kernel 3.13 - http://www.phoronix.com/scan.php?page=news_item&px=MTUxNTk -F2FS a filesystem made only for Flash file systems. - I am particularly skeptical about the "There's now NFTables as the eventual replacement to IPTables." Some filesystems benchmarks: http://www.phoronix.com/scan.php?page=article&item=linux_btrfs_311&num=3 http://www.phoronix.com/scan.php?page=article&item=linux_312_fs&num=3 I just find interesting that compression can actually increase your performance. Google's Go Lang 1.2 is released: http://blog.golang.org/go12 Cheers, Henrique.

Upgrade
by Clint Moyer Nov. 11, 2013

Nov. 11, 2013

My main PC is long overdue for an update. I dual boot Win7 and Linux Mint. Light use, no gaming or heavy graphics. A few questions: Are there any gotchas using a CPU with integrated GPU? Not talking about mobo chipset graphic, but something like an AMD CPU with embedded ATI graphic. I haven't yet dealt with any motherboard with UEFI bios. I know there was a big uproar over Secure Boot. Is this going to give me any headache installing Linux? Is there any specific manufacturer that implements it more properly than others? Asus has been my goto brand. I'll retain my current HDDs for storage but would like to use an SSD for the OSes. I'd assume that's pretty transparent as far as installing Linux goes? Anything I need to worry about here? Any specific advice or recommendations will be appreciated. Thanks. Clint

Re: [Wlug] Wlug Digest, Vol 121, Issue 5
by David Hardy Nov. 10, 2013

When I got three new machines over this past year, they all came with Windows 8 (HP Pavilions) and Atheros ethernet controllers. I had to disable Secure Boot on the machines where I installed Linux and it was also a royal PITA dealing with the Atheros drivers. Ubuntu and Mint did not want to work with Atheros, and the one machine I finally put Linux on ended up working nicely with Fedora 19. One machine remains Windows 8 (and I had gotten stung pretty badly doing the Beta 8.1 "upgrade" so am keeping it at the 8 level.) Because of pending job stuff I have to, for now, keep a second machine running Windows Server 2012R2, which works fine with the Atheros (Windows 2008R2 did not). And my remaining machine runs Fedora 19 with a hardened Virtual Box running a Whonix vm running Tor and an offshore mail client. Good luck; YMMV, obviously, but I think the disabling of Secure Boot may be your first order of business.

OpenWRT on WNDR3800 home router - my install thoughts
by joel d Nov. 4, 2013

Nov. 4, 2013

Decided to try OpenWRT after Jim Getty's talk and strong recommendation last month for improved security and reduced local buffer bloat. What follows is my experience / thoughts from this process. I would happily bring the hardware to demo at a future meeting if there is interest. Likely wouldn't be a full meeting but a 10-15 minute filler. More likely Q&A than anything else. I decided to go with different router/firewall hardware so I bought a Netgear WNDR3800 which Jim mentioned and is also a favorite of the OpenWRT crowd. Mine was used and $50 shipped from e-bay. This model is one model old and no longer available new. FYI: Netgear website lists it as "out of support". My WNDR3800 was used prior, so I needed to do a hard firmware reset on the bottom of router with a paperclip (didn't know the prior IP used or the admin password). Once reset and rebooted, router worked fine and could login to the "default" Netgear firmware and configuration. Default username & password is printed under the router. Downloaded the recommended OpenWRT firmware for this model. Needs to be full "factory" (instead of partial upgrade) and squashfs is recommended. Netgear WNDR3800 Firmware download link gets you OpenWRT version 10.X version which is not latest OpenWRT. Web browser login to Netgear webpage/firmware and followed "upgrade firmware" link while pointing to OpenWRT download file on local disk. The upgrade/re-flash took around 4 minutes and after a reboot worked fine. Set password and reconfigured router and WIFI with my specifics. Was up and working on OpenWRT v 10.x. Next day realized I had OpenWRT, but not latest stable version. Upgrade firmware link does not go to Internet directly, so first download OpenWRT v 12.4 with "upgrade" and "squashfs" and save to local disk. Second apply this via upgrade button in OpenWRT web link. I could likely have saved a step by grabbing the OpenWRT v12.4 for WNDR3800 with factory and squashfs. I bet this would have worked had I tried it (and saved a step). General thoughts after use for a week: OpenWRT does not have an "update direct to mother ship" feature best I can tell that downloads file and updates it from web interface. Not a show stopper for me. Instead need to know your version of OpenWRT and download an "upgrade" file and apply as two steps. This would only matter if router was used/maintained by a non-geek. Prior problem occurred with similar hardware WNDR3700 with latest Netgear firmware (happened with prior Linksys also). A few embedded WIFI devices in home would disconnect and fail randomly and at least weekly. Thus far these device annoyances have not occured since swap to WNDR3800 and OpenWRT. No idea why, but definitely A win! OpenWRT has transmit power level settings for the WIFI radio transmit. Can decide to bump up the WIFI radio settings if user chooses. Even if you melt/destroy them, a cool option if needed & tested. Firmware update for OpenWRT works from a laptop on WIFI, which in my experience Netgear & Linksys and other vendors do not support flash without a cabled ethernet port. So the OpenWRT update scripts the 1) copy file 2) apply file 3) reboot device. My Next Steps: In another week will likely repurpose the WNDR3700 likely as a WIFI gateway for the "cheap WIFI radio" devices, (mainly TV, roku, DVD, etc.). Not yet sure if I will use OpenWRT for this. Look into the option of external antennas for the WNDR3800. I live out in the country and have few neighbors to notice/know/care. If I can get there... improved & reliable WIFI signal at my mailbox would rock.

Idiot Service Providers
by Keith Wright Oct. 23, 2013

Oct. 23, 2013

On recomendation from someone on this list, I signed up for Speakeasy DSL. The helped me set up a primary name server (DNS) and they ran a secondary name server for a few extra dollars per month. This has been working well for about a decade. Speakeasy was sold to MegaPath, who yesterday sent me a message that included this: > Dear MegaPath Customer, > > This email is to advise you that MegaPath is > migrating its legacy Speakeasy ISP, web hosting, > webmail and DNS services to a more advanced platform. > > <Braindead "customer-experience" > happy market-talk deleted> > > Going forward, we will no longer support secondary > DNS services. If your domain is set up in this > manner, please be sure to make the proper changes to > avoid a post-migration service disruption. This all happens next Tuesday. I read this is "We are breaking what has worked for a decade, there is nothing you can do, have fun finding a new ISP in two days." I was wall-punching cursing mad. When I calmed down a bit I began to think, if they don't break anything else, maybe it's not so bad. The system was designed to tolerate failure. _I_ was not designed to tolerate _intentional_ failure, but everything should still work if the secondary name server is broken. Since I have only one IP address on one DSL line, I never really saw the need for a secondary server in the first place. I run a primary server because (A) I like to think of myself as a programmer, and it is self education to figure out how to do it. (B) Sometimes I create subdomains and run test program servers in them. The RFC's require a second name server, and the registrar asks for it, but who's going to care really? If the primary name server goes out, so do all other servers in the domain, since it's all really just one computer. What would you recommend? If anyone else has the same problem, I could be your secondary, and you could be mine. -- Keith
