My requirements are simple, it must be +cheap and locally encrypted (in other words, I keep the encryption +keys, the storage provider do not have access to my private files). +One idea me and my friends had many years ago, before the cloud +storage providers showed up, was to use Google mail as storage, +writing a Linux block device storing blocks as emails in the mail +service provided by Google, and thus get heaps of free space. On top +of this one can add encryption, RAID and volume management to have +lots of (fairly slow, I admit that) cheap and encrypted storage. But +I never found time to implement such system. But the last few weeks I +have looked at a system called +<a href="https://bitbucket.org/nikratio/s3ql/">S3QL</a>, a locally +mounted network backed file system with the features I need.</p> + +<p>S3QL is a fuse file system with a local cache and cloud storage, +handling several different storage providers, any with Amazon S3, +Google Drive or OpenStack API. There are heaps of such storage +providers. S3QL can also use a local directory as storage, which +combined with sshfs allow for file storage on any ssh server. S3QL +include support for encryption, compression, de-duplication, snapshots +and immutable file systems, allowing me to mount the remote storage as +a local mount point, look at and use the files as if they were local, +while the content is stored in the cloud as well. This allow me to +have a backup that should survive fire. The file system can not be +shared between several machines at the same time, as only one can +mount it at the time, but any machine with the encryption key and +access to the storage service can mount it if it is unmounted.</p> + +<p>It is simple to use. I'm using it on Debian Wheezy, where the +package is included already. So to get started, run <tt>apt-get +install s3ql</tt>. Next, pick a storage provider. I ended up picking +Greenqloud, after reading their nice recipe on +<a href="https://greenqloud.zendesk.com/entries/44611757-How-To-Use-S3QL-to-mount-a-StorageQloud-bucket-on-Debian-Wheezy">how +to use S3QL with their Amazon S3 service</a>, because I trust the laws +in Iceland more than those in USA when it come to keeping my personal +data safe and private, and thus would rather spend money on a company +in Iceland. Another nice recipe is available from the article +<a href="http://www.admin-magazine.com/HPC/Articles/HPC-Cloud-Storage">S3QL +Filesystem for HPC Storage</a> by Jeff Layton in the HPC section of +Admin magazine. When the provider is picked, figure out how to get +the API key needed to connect to the storage API. With Greencloud, +the key did not show up until I had added payment details to my +account.</p> + +<p>Armed with the API access details, it is time to create the file +system. First, create a new bucket in the cloud. This bucket is the +file system storage area. I picked a bucket name reflecting the +machine that was going to store data there, but any name will do. +I'll refer to it as <tt>bucket-name</tt> below. In addition, one need +the API login and password, and a locally created password. Store it +all in ~root/.s3ql/authinfo2 like this: + +<p><blockquote><pre> +[s3c] +storage-url: s3c://s.greenqloud.com:443/bucket-name +backend-login: API-login +backend-password: API-password +fs-passphrase: local-password +</pre></blockquote></p> + +<p>I create my local passphrase using <tt>pwget 50</tt> or similar, +but any sensible way to create a fairly random password should do it. +Armed with these details, it is now time to run mkfs, entering the API +details and password to create it:</p> + +<p><blockquote><pre> +# mkdir -m 700 /var/lib/s3ql-cache +# mkfs.s3ql --cachedir /var/lib/s3ql-cache --authfile /root/.s3ql/authinfo2 \ + --ssl s3c://s.greenqloud.com:443/bucket-name +Enter backend login: +Enter backend password: +Before using S3QL, make sure to read the user's guide, especially +the 'Important Rules to Avoid Loosing Data' section. +Enter encryption password: +Confirm encryption password: +Generating random encryption key... +Creating metadata tables... +Dumping metadata... +..objects.. +..blocks.. +..inodes.. +..inode_blocks.. +..symlink_targets.. +..names.. +..contents.. +..ext_attributes.. +Compressing and uploading metadata... +Wrote 0.00 MB of compressed metadata. +# </pre></blockquote></p> + +<p>The next step is mounting the file system to make the storage available. + +<p><blockquote><pre> +# mount.s3ql --cachedir /var/lib/s3ql-cache --authfile /root/.s3ql/authinfo2 \ + --ssl --allow-root s3c://s.greenqloud.com:443/bucket-name /s3ql +Using 4 upload threads. +Downloading and decompressing metadata... +Reading metadata... +..objects.. +..blocks.. +..inodes.. +..inode_blocks.. +..symlink_targets.. +..names.. +..contents.. +..ext_attributes.. +Mounting filesystem... +# df -h /s3ql +Filesystem Size Used Avail Use% Mounted on +s3c://s.greenqloud.com:443/bucket-name 1.0T 0 1.0T 0% /s3ql +# +</pre></blockquote></p> + +<p>The file system is now ready for use. I use rsync to store my +backups in it, and as the metadata used by rsync is downloaded at +mount time, no network traffic (and storage cost) is triggered by +running rsync. To unmount, one should not use the normal umount +command, as this will not flush the cache to the cloud storage, but +instead running the umount.s3ql command like this: + +<p><blockquote><pre> +# umount.s3ql /s3ql +# +</pre></blockquote></p> + +<p>There is a fsck command available to check the file system and +correct any problems detected. This can be used if the local server +crashes while the file system is mounted, to reset the "already +mounted" flag. This is what it look like when processing a working +file system:</p> + +<p><blockquote><pre> +# fsck.s3ql --force --ssl s3c://s.greenqloud.com:443/bucket-name +Using cached metadata. +File system seems clean, checking anyway. +Checking DB integrity... +Creating temporary extra indices... +Checking lost+found... +Checking cached objects... +Checking names (refcounts)... +Checking contents (names)... +Checking contents (inodes)... +Checking contents (parent inodes)... +Checking objects (reference counts)... +Checking objects (backend)... +..processed 5000 objects so far.. +..processed 10000 objects so far.. +..processed 15000 objects so far.. +Checking objects (sizes)... +Checking blocks (referenced objects)... +Checking blocks (refcounts)... +Checking inode-block mapping (blocks)... +Checking inode-block mapping (inodes)... +Checking inodes (refcounts)... +Checking inodes (sizes)... +Checking extended attributes (names)... +Checking extended attributes (inodes)... +Checking symlinks (inodes)... +Checking directory reachability... +Checking unix conventions... +Checking referential integrity... +Dropping temporary indices... +Backing up old metadata... +Dumping metadata... +..objects.. +..blocks.. +..inodes.. +..inode_blocks.. +..symlink_targets.. +..names.. +..contents.. +..ext_attributes.. +Compressing and uploading metadata... +Wrote 0.89 MB of compressed metadata. +# +</pre></blockquote></p> + +<p>Thanks to the cache, working on files that fit in the cache is very +quick, about the same speed as local file access. Uploading large +amount of data is to me limited by the bandwidth out of and into my +house. Uploading 685 MiB with a 100 MiB cache gave me 305 kiB/s, +which is very close to my upload speed, and downloading the same +Debian installation ISO gave me 610 kiB/s, close to my download speed. +Both were measured using <tt>dd</tt>. So for me, the bottleneck is my +network, not the file system code. I do not know what a good cache +size would be, but suspect that the cache should e larger than your +working set.</p> + +<p>I mentioned that only one machine can mount the file system at the +time. If another machine try, it is told that the file system is +busy:</p> + +<p><blockquote><pre> +# mount.s3ql --cachedir /var/lib/s3ql-cache --authfile /root/.s3ql/authinfo2 \ + --ssl --allow-root s3c://s.greenqloud.com:443/bucket-name /s3ql +Using 8 upload threads. +Backend reports that fs is still mounted elsewhere, aborting. +# +</pre></blockquote></p> + +<p>The file content is uploaded when the cache is full, while the +metadata is uploaded once every 24 hour by default. To ensure the +file system content is flushed to the cloud, one can either umount the +file system, or ask S3QL to flush the cache and metadata using +s3qlctrl: + +<p><blockquote><pre> +# s3qlctrl upload-meta /s3ql +# s3qlctrl flushcache /s3ql +# +</pre></blockquote></p> + +<p>If you are curious about how much space your data uses in the +cloud, and how much compression and deduplication cut down on the +storage usage, you can use s3qlstat on the mounted file system to get +a report:</p> + +<p><blockquote><pre> +# s3qlstat /s3ql +Directory entries: 9141 +Inodes: 9143 +Data blocks: 8851 +Total data size: 22049.38 MB +After de-duplication: 21955.46 MB (99.57% of total) +After compression: 21877.28 MB (99.22% of total, 99.64% of de-duplicated) +Database size: 2.39 MB (uncompressed) +(some values do not take into account not-yet-uploaded dirty blocks in cache) +# +</pre></blockquote></p> + +<p>I mentioned earlier that there are several possible suppliers of +storage. I did not try to locate them all, but am aware of at least +<a href="https://www.greenqloud.com/">Greenqloud</a>, +<a href="http://drive.google.com/">Google Drive</a>, +<a href="http://aws.amazon.com/s3/">Amazon S3 web serivces</a>, +<a href="http://www.rackspace.com/">Rackspace</a> and +<a href="http://crowncloud.net/">Crowncloud</A>. The latter even +accept payment in Bitcoin. Pick one that suit your need. Some of +them provide several GiB of free storage, but the prize models are +quite different and you will have to figure out what suits you +best.</p> + +<p>While researching this blog post, I had a look at research papers +and posters discussing the S3QL file system. There are several, which +told me that the file system is getting a critical check by the +science community and increased my confidence in using it. One nice +poster is titled +"<a href="http://www.lanl.gov/orgs/adtsc/publications/science_highlights_2013/docs/pg68_69.pdf">An +Innovative Parallel Cloud Storage System using OpenStack’s SwiftObject +Store and Transformative Parallel I/O Approach</a>" by Hsing-Bung +Chen, Benjamin McClelland, David Sherrill, Alfred Torrez, Parks Fields +and Pamela Smith. Please have a look.</p> + +<p>Given my problems with different file systems earlier, I decided to +check out the mounted S3QL file system to see if it would be usable as +a home directory (in other word, that it provided POSIX semantics when +it come to locking and umask handling etc). Running +<a href="http://people.skolelinux.org/pere/blog/Testing_if_a_file_system_can_be_used_for_home_directories___.html">my +test code to check file system semantics</a>, I was happy to discover that +no error was found. So the file system can be used for home +directories, if one chooses to do so.</p> + +<p>If you do not want a locally file system, and want something that +work without the Linux fuse file system, I would like to mention the +<a href="http://www.tarsnap.com/">Tarsnap service</a>, which also +provide locally encrypted backup using a command line client. It have +a nicer access control system, where one can split out read and write +access, allowing some systems to write to the backup and others to +only read from it.</p> + +<p>As usual, if you use Bitcoin and want to show your support of my +activities, please send Bitcoin donations to my address +<b><a href="bitcoin:15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&label=PetterReinholdtsenBlog">15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b</a></b>.</p> + + + + + EU-domstolen bekreftet i dag at datalagringsdirektivet er ulovlig + http://people.skolelinux.org/pere/blog/EU_domstolen_bekreftet_i_dag_at_datalagringsdirektivet_er_ulovlig.html + http://people.skolelinux.org/pere/blog/EU_domstolen_bekreftet_i_dag_at_datalagringsdirektivet_er_ulovlig.html + Tue, 8 Apr 2014 11:30:00 +0200 + <p>I dag kom endelig avgjørelsen fra EU-domstolen om +datalagringsdirektivet, som ikke overraskende ble dømt ulovlig og i +strid med borgernes grunnleggende rettigheter.

But there are heaps of machines still running +Windows XP, and depending on Windows XP to run their applications, and +upgrading will be expensive, both when it comes to money and when it +comes to the amount of effort needed to migrate from Windows XP to a +new operating system. Some obvious options (buy new a Windows +machine, buy a MacOSX machine, install Linux on the existing machine) +are already well known and covered elsewhere. Most of them involve +leaving the user applications installed on Windows XP behind and +trying out replacements or updated versions.

It is +a Windows clone running directly on the hardware, so quite different +from the approach taken by <a href="http://www.winehq.org/">the Wine +project</a>, which make it possible to run Windows binaries on +Linux.</p> + +<p>The ReactOS project share code with the Wine project, so most +shared libraries available on Windows are already implemented already. +There is also a software manager like the one we are used to on Linux, +allowing the user to install free software applications with a simple +click directly from the Internet. Check out the +<a href="http://www.reactos.org/screenshots">screen shots on the +project web site</a> for an idea what it look like (it looks just like +Windows before metro).</p> + +<p>I do not use ReactOS myself, preferring Linux and Unix like +operating systems. I've tested it, and it work fine in a virt-manager +virtual machine. The browser, minesweeper, notepad etc is working +fine as far as I can tell. Unfortunately, my main test application +is the software included on a CD with the Lego Mindstorms NXT, which +seem to install just fine from CD but fail to leave any binaries on +the disk after the installation. So no luck with that test software. +No idea why, but hope someone else figure out and fix the problem. +I've tried the ReactOS Live ISO on a physical machine, and it seemed +to work just fine.

The most -know ones are the killer drones used by some government to murder -people they do not like without giving them the chance of a fair -trial, but the technology have many good uses too, from mapping and -forest maintenance to photography and search and rescue. I am sure it -is just a question of time before "bad drones" are in the hands of -private enterprises and not only state criminals but petty criminals -too. The drone technology is very useful and very dangerous. To have -some control over the use of drones, I agree with Daniel Suarez in his -TED talk -"<a href="https://archive.org/details/DanielSuarez_2013G">The kill -decision shouldn't belong to a robot</a>", where he suggested this -little gem to keep the good while limiting the bad use of drones:</p> - -<blockquote> - -<p>Each robot and drone should have a cryptographically signed -I.D. burned in at the factory that can be used to track its movement -through public spaces. We have license plates on cars, tail numbers on -aircraft. This is no different. And every citizen should be able to -download an app that shows the population of drones and autonomous -vehicles moving through public spaces around them, both right now and -historically. And civic leaders should deploy sensors and civic drones -to detect rogue drones, and instead of sending killer drones of their -own up to shoot them down, they should notify humans to their -presence. And in certain very high-security areas, perhaps civic -drones would snare them and drag them off to a bomb disposal facility.</p> - -<p>But notice, this is more an immune system than a weapons system. It -would allow us to avail ourselves of the use of autonomous vehicles -and drones while still preserving our open, civil society.</p> - -</blockquote> - -<p>The key is that <em>every citizen</em> should be able to read the -radio beacons sent from the drones in the area, to be able to check -both the government and others use of drones. For such control to be -effective, everyone must be able to do it. What should such beacon -contain? At least formal owner, purpose, contact information and GPS -location. Probably also the origin and target position of the current -flight. And perhaps some registration number to be able to look up -the drone in a central database tracking their movement. Robots -should not have privacy. It is people who need privacy.</p> + Public Trusted Timestamping services for everyone + http://people.skolelinux.org/pere/blog/Public_Trusted_Timestamping_services_for_everyone.html + http://people.skolelinux.org/pere/blog/Public_Trusted_Timestamping_services_for_everyone.html + Tue, 25 Mar 2014 12:50:00 +0100 + <p>Did you ever need to store logs or other files in a way that would +allow it to be used as evidence in court, and needed a way to +demonstrate without reasonable doubt that the file had not been +changed since it was created? Or, did you ever need to document that +a given document was received at some point in time, like some +archived document or the answer to an exam, and not changed after it +was received? The problem in these settings is to remove the need to +trust yourself and your computers, while still being able to prove +that a file is the same as it was at some given time in the past.</p> + +<p>A solution to these problems is to have a trusted third party +"stamp" the document and verify that at some given time the document +looked a given way. Such +<a href="https://en.wikipedia.org/wiki/Notarius">notarius</a> service +have been around for thousands of years, and its digital equivalent is +called a +<a href="http://en.wikipedia.org/wiki/Trusted_timestamping">trusted +timestamping service</a>. <a href="http://www.ietf.org/">The Internet +Engineering Task Force</a> standardised how such service could work a +few years ago as <a href="http://tools.ietf.org/html/rfc3161">RFC +3161</a>. The mechanism is simple. Create a hash of the file in +question, send it to a trusted third party which add a time stamp to +the hash and sign the result with its private key, and send back the +signed hash + timestamp. Both email, FTP and HTTP can be used to +request such signature, depending on what is provided by the service +used. Anyone with the document and the signature can then verify that +the document matches the signature by creating their own hash and +checking the signature using the trusted third party public key. +There are several commercial services around providing such +timestamping. A quick search for +"<a href="https://duckduckgo.com/?q=rfc+3161+service">rfc 3161 +service</a>" pointed me to at least +<a href="https://www.digistamp.com/technical/how-a-digital-time-stamp-works/">DigiStamp</a>, +<a href="http://www.quovadisglobal.co.uk/CertificateServices/SigningServices/TimeStamp.aspx">Quo +Vadis</a>, +<a href="https://www.globalsign.com/timestamp-service/">Global Sign</a> +and <a href="http://www.globaltrustfinder.com/TSADefault.aspx">Global +Trust Finder</a>. The system work as long as the private key of the +trusted third party is not compromised.</p> + +<p>But as far as I can tell, there are very few public trusted +timestamp services available for everyone. I've been looking for one +for a while now. But yesterday I found one over at +<a href="https://www.pki.dfn.de/zeitstempeldienst/">Deutches +Forschungsnetz</a> mentioned in +<a href="http://www.d-mueller.de/blog/dealing-with-trusted-timestamps-in-php-rfc-3161/">a +blog by David Müller</a>. I then found +<a href="http://www.rz.uni-greifswald.de/support/dfn-pki-zertifikate/zeitstempeldienst.html">a +good recipe on how to use the service</a> over at the University of +Greifswald.</p> + +<p><a href="http://www.openssl.org/">The OpenSSL library</a> contain +both server and tools to use and set up your own signing service. See +the ts(1SSL), tsget(1SSL) manual pages for more details. The +following shell script demonstrate how to extract a signed timestamp +for any file on the disk in a Debian environment:</p> + +<p><blockquote><pre> +#!/bin/sh +set -e +url="http://zeitstempel.dfn.de" +caurl="https://pki.pca.dfn.de/global-services-ca/pub/cacert/chain.txt" +reqfile=$(mktemp -t tmp.XXXXXXXXXX.tsq) +resfile=$(mktemp -t tmp.XXXXXXXXXX.tsr) +cafile=chain.txt +if [ ! -f $cafile ] ; then + wget -O $cafile "$caurl" +fi +openssl ts -query -data "$1" -cert | tee "$reqfile" \ + | /usr/lib/ssl/misc/tsget -h "$url" -o "$resfile" +openssl ts -reply -in "$resfile" -text 1>&2 +openssl ts -verify -data "$1" -in "$resfile" -CAfile "$cafile" 1>&2 +base64 < "$resfile" +rm "$reqfile" "$resfile" +</pre></blockquote></p> + +<p>The argument to the script is the file to timestamp, and the output +is a base64 encoded version of the signature to STDOUT and details +about the signature to STDERR. Note that due to +<a href="http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=742553">a bug +in the tsget script</a>, you might need to modify the included script +and remove the last line.

My preferred method at the moment is +to store a full copy of the ISO on a hard drive, and use VLC, Popcorn +Hour or other useful players to view the resulting file. This way the +subtitles and bonus material are still available and using the ISO is +just like inserting the original DVD record in the DVD player.</p> + +<p>Earlier I used dd for taking security copies, but it do not handle +DVDs giving read errors (which are quite a few of them).

It is +<a href="http://packages.qa.debian.org/p/python-dvdvideo.html">in Debian +already</a> and the binary package name is python3-dvdvideo. Instead +of trying to read every block from the DVD, it parses the file +structure and figure out which block on the DVD is actually in used, +and only read those blocks from the DVD. This work surprisingly well, +and I have been able to almost backup my entire DVD collection using +this method.</p> + +<p>So far, python-dvdvideo have failed on between 10 and +20 DVDs, which is a small fraction of my collection. The most common +problem is +<a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=720831">DVDs +using UTF-16 instead of UTF-8 characters</a>, which according to +Bastian is against the DVD specification (and seem to cause some +players to fail too). A rarer problem is what seem to be inconsistent +DVD structures, as the python library +<a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=723079">claim +there is a overlap between objects</a>. An equally rare problem claim +<a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=741878">some +value is out of range</a>. No idea what is going on there. I wish I +knew enough about the DVD format to fix these, to ensure my movie +collection will stay with me in the future.</p> + +<p>So, if you need to keep your DVDs safe, back them up using +python-dvdvideo. :)</p> - Running TP-Link MR3040 as a batman-adv mesh node using openwrt - http://people.skolelinux.org/pere/blog/Running_TP_Link_MR3040_as_a_batman_adv_mesh_node_using_openwrt.html - http://people.skolelinux.org/pere/blog/Running_TP_Link_MR3040_as_a_batman_adv_mesh_node_using_openwrt.html - Sun, 10 Nov 2013 23:00:00 +0100 - <p>Continuing my research into mesh networking, I was recommended to -use TP-Link 3040 and 3600 access points as mesh nodes, and the pair I -bought arrived on Friday. Here are my notes on how to set up the -MR3040 as a mesh node using -<a href="http://www.openwrt.org/">OpenWrt</a>.</p> - -<p>I started by following the instructions on the OpenWRT wiki for -<a href="http://wiki.openwrt.org/toh/tp-link/tl-mr3040">TL-MR3040</a>, -and downloaded -<a href="http://downloads.openwrt.org/snapshots/trunk/ar71xx/openwrt-ar71xx-generic-tl-mr3040-v2-squashfs-factory.bin">the -recommended firmware image</a> -(openwrt-ar71xx-generic-tl-mr3040-v2-squashfs-factory.bin) and -uploaded it into the original web interface. The flashing went fine, -and the machine was available via telnet on the ethernet port. After -logging in and setting the root password, ssh was available and I -could start to set it up as a batman-adv mesh node.</p> - -<p>I started off by reading the instructions from -<a href="http://wirelessafrica.meraka.org.za/wiki/index.php?title=Antoine's_Research">Wireless -Africa</a>, which had quite a lot of useful information, but -eventually I followed the recipe from the Open Mesh wiki for -<a href="http://www.open-mesh.org/projects/batman-adv/wiki/Batman-adv-openwrt-config">using -batman-adv on OpenWrt</a>. A small snag was the fact that the -<tt>opkg install kmod-batman-adv</tt> command did not work as it -should. The batman-adv kernel module would fail to load because its -dependency crc16 was not already loaded. I -<a href="https://dev.openwrt.org/ticket/14452">reported the bug</a> to -the openwrt project and hope it will be fixed soon.
