Fwd: WikiLeaks may be under attack
by David Nicol 16 Jun '10

16 Jun '10

---------- Forwarded message ---------- From: WikiLeaks <wl-office(a)sunshinepress.org> Date: Tue, Jun 15, 2010 at 4:10 AM Subject: WikiLeaks may be under attack To: some pseudonym or other WikiLeaks may be under attack. You were generous enough to write to us, but we have not had the labor resources to respond. Your support is important to us. Please read all of this email to understand what is going on. We apologize for not getting back to you before. It is not through any lack of interest on our part, but an enforced lack of resources. One of our alleged sources, a young US intelligence analyst, Bradley Manning, has been detained and shipped to a US military prison in Kuwait, where he is being held without trail. Mr. Manning is alleged to have acted according to his conscious and leaked to us the Collateral Murder video and the video of a massacre that took place in Afghanistan last year at Garani. The Garani massacre, which we are still working on, killed over 100 people, mostly children. Mr. Manning allegedly also sent us 260,000 classified US Department cables, reporting on the actions of US Embassy's engaging in abusive actions all over the world. We have denied the allegation, but the US government is acting as if the allegation is true and we do have a lot of other material that exposes human rights abuses by the United States government. Mr. Manning was allegedly exposed after talking to an unrelated "journalist" who then worked with the US government to detain him. Some background on the Manning case: http://fdlaction.firedoglake.com/2010/06/11/transcript-daniel-ellsberg-says… http://en.wikipedia.org/wiki/Bradley_Manning http://www.wired.com/threatlevel/2010/06/leak/ http://www.wired.com/threatlevel/2010/06/wikileaks-chat/ http://www.wired.com/threatlevel/2010/06/state-department-anxious/ http://www.state.gov/r/pa/prs/dpb/2010/06/143011.htm [ note that there are some questions about the Wired reportage, see: http://www.boingboing.net/2010/06/13/video-wikileaks-foun.html#comment-8096… ] WikiLeaks a small organization going through enormous growth and operating in an adverserial, high-security environment which can make communication time consuming and the acquisition of new staff and volunteers, also difficult since they require high levels of trust. To try and deal with our growth and the current difficult situation, we want to get you to work together with our other supporters to set up a "Friends of WikiLeaks" group in your area. We have multiple supporters in most countries and would like to see them be a strong and independent force. Please write to friends(a)sunshinepress.org if you are interested in helping with Friends of WikiLeaks in your area. You will receive further instructions. We also have significant unexpected legal costs (for example flying a legal team to Kuwait, video production. Collateral Murder production costs were $50,000 all up). Any financial contributions will be of IMMEDIATE assistance. http://wikileaks.org/wiki/Special:Support Please donate and tell the world that you have done so. Encourage all your friends to follow the example you set, after all, courage is contagious. Julian Assange Editor in Chief WIKILEAKS

Synology & Fsck
by Sean Crago 06 Jun '10

06 Jun '10

If the list is coming back to life, then I've got a weird but hopefully simple problem for you: I've got a Synology DiskStation DS209 NAS that's giving me erroneous free space readings, or erroneous du output. On installation, it dedicated 2.4GB to its root partition /dev/md0 and according to du -cx / is using less than 587192K of that space. Unfortunately, however, df says it's full. bash-3.2# df -k Filesystem 1K-blocks Used Available Use% Mounted on rootfs 2451064 2425764 0 100% / /dev/root 2451064 2425764 0 100% / bash-3.2# mount /dev/md0 on / type ext3 (rw,data=ordered) As a result, any number of apps from the stock firmware are prevented from running and those that do hobble along spam the logs to the point of uselessness w/complaints. The catch? I can't find a safe way to fsck it. Conventional shutdown commands to force a fsck aren't an option/are just plain missing on the box. Using tune2fs to set the check interval ridiculously low to force a check upon reboot similarly didn't work. Unfortunately, the ARM-based architecture also doesn't support booting to a removable USB device, knocking out the only other safe way I can think of to fsck it. Pop new firmware on to start from scratch? I'd love to at this point, but the firmware installation process requires 1024 megs of free disk space. Thoughts? Any ideas on how to safely get it cleaned up and accurately reporting its free space while the root filesystem is live and booted? -Sean

packed permission bits in file systems?
by David Nicol 03 Jun '10

03 Jun '10

http://en.wikipedia.org/wiki/Talk:Filesystem_permissions#Packed_permission_… Clearly, ext3 has moved beyond "packed permission bits" if that ever was a production concept. [david@hexaflexagon scrabble]$ touch BLOP [david@hexaflexagon scrabble]$ ls -l BLOP -rw-r--r-- 1 david david 0 Jun 3 04:11 BLOP [david@hexaflexagon scrabble]$ chmod o+x BLOP [david@hexaflexagon scrabble]$ ls -l BLOP -rw-r--r-x 1 david david 0 Jun 3 04:11 BLOP [david@hexaflexagon scrabble]$ Under packed permissions, granting for OTHERS would grant for USER and GROUP too. Here's my question: When did packed permissions stop being used, if they ever were? Does anyone else remember "chmod o+w foo" silently implying "chmod ugo+w foo" and if so how log ago was that? -- "I'm not giving in an inch to fear" --David Crosby

Are there any temp files or old logs that you can delete to free up space for fresh firmware? -------------------------- Brian Kelsay Sr. IT Support Specialist Anadarko Industries Inc. working for Technical Support Division (TSD) USDA/OCIO/ITS/TSD/LO-KC Office: 816-823-4859 Mobile: 816-769-5615 Email: brian.kelsay(a)kcc.usda.gov Message Sent using BlackBerry Device ________________________________ From: kclug-bounces(a)kclug.org <kclug-bounces(a)kclug.org> To: KCLUG <kclug(a)kclug.org> Sent: Wed Jun 02 12:08:30 2010 Subject: Re: Synology & Fsck On Wed, Jun 2, 2010 at 10:47 PM, Sean Crago <cragos(a)gmail.com<mailto:cragos@gmail.com>> wrote: If the list is coming back to life, then I've got a weird but hopefully simple problem for you: I've got a Synology DiskStation DS209 NAS that's giving me erroneous free space readings, or erroneous du output.

Also, power situation is abysmal here, and I'm not convinced it's shutting down properly when it detects that it's on UPS power.
