Console
by Robert Dyck 25 Feb '13

25 Feb '13

I have a machine running Ubuntu Server 12.10; this is server, not desktop, so command line only. The CRT monitor fried. I have an old LCD monitor, but it only accepts 800x600 resolution at 60Hz. I'm trying to get that working as the console. I can get in via SSH using PuTTY from a Windows machine, but that's not a long term solution for a few reasons. This monitor does display BIOS POST, and the Grub menu, but does not display the login prompt. I tried "sudo dpkg-reconfigure console-setup" but that just has encoding, character set, font, and font size. Nothing for console resolution. I tried editing /etc/default/console-setup to add "GRUB_GFXPAYLOAD_LINUX=800x600". The console is visible during POST, and the GRUB menu, but then changes to an unsupported mode. I haven't even looked at anything that could be put in .profile because I don't get that far. I can't even see the login prompt. Could you guys help me? Thanks, Rob Dyck

Odd LDAP issue
by Robert Keizer 20 Feb '13

20 Feb '13

Greetings, At work I have an OpenLDAP daemon running. ( 2.4.28, standard ubu 12.04 repo before someone asks ). For those who don't know: OpenLDAP as of 2.3+ allows the storage of the LDAP schema to reside in LDAP. As a result, you can modify the schema in runtime. I have been taking full advantage of this feature and adding attributes and classes when I need, rather than planning for production downtime. I couldn't for the life of me figure out why replacing an olcObjectClass in runtime wasn't working properly. I was getting a "Duplicate objectClass" error. That may seem like a simple fix. It would have been if it actually had been a duplicate. I spent quite a long time working away, turning OpenLDAP debug up to 9 which is copious in and of itself. In the end this is what I found. My guess is that I have stumbled upon an OpenLDAP bug, or perhaps that some developer designed it to on SIGHUP refresh its internal structures. # ldapmodify -Y EXTERNAL -H ldapi:/// -f ./tmp.ldif .. ( snip ) .. modifying entry "cn={5}yst,cn=schema,cn=config" ldap_modify: Other (e.g., implementation specific) error (80) additional info: olcObjectClasses: Duplicate objectClass: "1.3.6.1.4.1.40605.1.1.1.1.1" # /etc/init.d/slapd restart * Stopping OpenLDAP slapd ...done. * Starting OpenLDAP slapd ...done. # ldapmodify -Y EXTERNAL -H ldapi:/// -f ./tmp.ldif .. ( snip ) .. modifying entry "cn={5}yst,cn=schema,cn=config" I am inclined to believe this is a bug in OpenLDAP because the first time after a fresh start I am able to make the modification, with the same LDIF. Thoughts? Is there some face-palming worthy piece of documentation out there that explains this? Rob

Fwd: SkullSpace Crypto night Wednesday! [Everyone is invited!]
by Colin Stanners 20 Feb '13

20 Feb '13

To other Winnipeg technology-oriented organizations: here's a technical event at Sksp, if you can distribute to anyone who would be interested. Sorry for the late announcement, no one here is really a "promotion" person, I'm trying to setup a better/faster system to announce our events to other organizations... ---------- Forwarded message ---------- From: Ron <ron(a)skullsecurity.net> Date: Tue, Feb 19, 2013 at 8:22 AM Subject: [SkullSpace-Announce] Crypto night: TOMORROW! [Everyone is invited!] To: announce(a)lists.skullspace.ca -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hey everybody, In honour of my Shmoocon talk - which went *exceptionally* well on Saturday - we're doing some crypto talks at SkullSpace tomorrow! It's gonna be a great night, and everybody is invited! The target audience is developers or security people. Anybody technical will have a good time, I suspect. I'm gonna cover the basic crypto constructs we're attacking, then talk about how to attack them. We aren't attacking the math of crypto at all - I don't do math - but rather how they're implemented. *Everybody is welcome, whether or not you're a member!!* We're gonna be getting some pizza, if you plan to eat then please bring a $5 or $10 donation. I'm paying for the pizza out of my own pocket, so it'd be nice if others would pitch in. The night is going to look something like this: ======================================================================== 6:00pm - I'm gonna aim to be there for 6 to unlock the doors and set up/greet/socialize/hang out ======================================================================== 6:30pm - PIZZA ======================================================================== 7:00 - 7:05 - Ron "iagox86" Bowes: Welcome A quick welcome/greeting from me, an intro of the speakers, and a bit about SkullSpace if we have a lot of guests showing up. ======================================================================== 7:05 - 7:20 - Colin "Phoul" Childs: "Introducing FROST" FROST is a method for stealing data off locked phones using a coldboot-style attack ======================================================================== 7:25 - 7:40 - Alex "AlexWebr" Weber: "I Can Hear You Tunneling" Alex will be presenting - for the first time ever! - a tool he's developing to discover information from SSH sessions based on packet timings. ======================================================================== 7:45 - 8:00 - Mak "mak" Kolybabi: TBA Mak... well, we all love Mak. He'll talk about something cool. I have faith ======================================================================== 8:05 - 9:15 - Ron "iagox86" Bowes: Crypto: You're doing it wrong Ron will be doing a reprise of his Shmoocon talk about how to fail at crypto. It was well received at Shmoocon and - while this is a somewhat different audience - plans to give the same talk at SkullSpace! ======================================================================== After the talks, we'll hang around for awhile for questions, comments, and general hacking. Feel free to hang out with us! See you all tomorrow!

Re: [RndTbl] view client on Linux
by Adam Thompson 20 Feb '13

20 Feb '13

Considering how shabby overall VMWare client support is for everything non-Windows, that wouldn't surprise me. You still can't deploy a vSphere environment without a Windows workstation to at least bootstrap it, for example. (Although that Windows system could be a VM inside Workstation on Linux...) -Adam

view client on Linux
by Kat 20 Feb '13

20 Feb '13

Am I reading this right? VMware's View Client for Linux is at version 1.7.0. Really? And the Google Code open version is at 4.5.0, but doesn't support PCoIP? I have no other alternatives??? I can kinda made do with RDP, but I don't want to. -- ------------------------------------------------------------ Katherine Scrupa Network Technology CCNA, Hons.

Doug Shewfelt's memorial service
by Gilbert E. Detillieux 13 Feb '13

13 Feb '13

Doug Shewfelt's memorial service will be held on Friday, Feb. 15 at 2:00pm at St. Andrew's United Church in Manitou MB. A private family internment service will precede the public service. If you are planning to attend, please let me know via e-mail. I'll collect the list of names, and pass it along to Dave Clement, who asked for responses (to get an attendance estimate). Thank you. For further information please check the web site: http://www.wheatlandfs.com/shewfelt-douglas/ The church is located at the corner of Hamilton St. and Fuller Ave. in Manitou: http://goo.gl/maps/nr1yn To get to Manitou, take highway 3 past Carman and Morden, and stay on highway 3 right to Manitou. Alternatively, it may be slightly shorter to turn west onto highway 23 between Carman and Morden, then south onto highway 244 to Manitou. (Google Maps also suggests taking highway 2 from Winnipeg, then south on highway 244.) Taking highway 23 has the advantage that you can see Manitoba Hydro's wind farm up close. It's impressive if you haven't seen it before. -- Gilbert E.

High powered PCI wireless card
by Paul Sierks 13 Feb '13

13 Feb '13

Thought I might ask if anyone knows where I might get a high powered PCIe or PCI wireless card. I've seen the Alfa USB's and they have a nice 2 watt adapter ( AWUS036NHR ), decided to order one up and try it out but I'd still really like a internal variant. Anyone? Thanks, Paul

BruXy: Housenka – a game just in BASH
by Adam Thompson 09 Feb '13

09 Feb '13

http://bruxy.regnet.cz/web/linux/EN/housenka-bash-game/ Who says shell scripting has to be terribly painful? The code is actually quite readable. I especially like the use of the subshell to trigger SIGALRM, I would never have thought of that myself. (Thanks to Hack A Day) -Adam

Re: [RndTbl] Intel ethernet - h/w remote DoS exploit!
by Adam Thompson 08 Feb '13

In theory (I haven't tested it yet) it is remotely exploitable across routers. His *test* does require you to be on the same subnet. -Adam Trevor Cordes <trevor(a)tecnopolis.ca> wrote: >On 2013-02-06 Adam Thompson wrote: >> This guy explains it better than I can, but the meat of it is that a >> large number of Intel Ethernet controllers in the field are >> susceptible to a firmware bug that can shut down the Ethernet port >> remotely. > >Kind of scary.
