I love the color profiles www.piraccini.net made, go and visit his page if you are looking for them! Thanks a lot Maurizio!

But… just in case that something happens, I've mirrored them:

Unzip and put into these folders:

Windows

C:\Users\yourusername\AppData\Roaming\Adobe\CameraRaw\CameraProfiles

MAC OS

simple environment switch:

wget -e robots=off http://www.protected.url

This small snippet, executed as root, moves Docker from volume1 to volume2:

By default only password logins are allowed via SSH on a DiskStation, you can switch this by changing the configuration at /etc/ssh/sshd_config:

Search for these three lines and change their values to the listed ones:

RSAAuthentication yes PubkeyAuthentication yes AuthorizedKeysFile .ssh/authorized_keys

You can put your ssh key in your root user at /root/.ssh. For some reasons this won't work with the default admin user – so you will need to ssh with user root from now on.

For better security disable password logins by commenting in the following two lines with value no:

PasswordAuthentication no PermitEmptyPasswords no

When you experience a file system corruption which your Synology NAS can not repair itself, it becomes really hard to check it yourself since it is nearly impossible to unmount it for all the services running straight from the volume or accessing it.

There is an undocumented syno-task which helps in the progress:

# shut down all services syno_poweroff_task -d # re-activate the volumes vgchange -ay # check the wanted volume fsck.ext4 -pvf -C 0 /dev/vg1000/lv # If you get the message "UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY", try: fsck.ext4 -yvf -C 0 /dev/vg1000/lv

The first things I wanted to install on my new NAS were Sonarr, nzbget, Plex and CouchPotato – sadly only Plex was working, everything else was quitting with a Permission denied error.

It seems that with the newly released DSM 6 some changes were made and for some packages will need a shell in which they run.

Thats why you need to go thru this checklist to fix this (well, for the listed packages at least):

cat /var/packages/<PACKAGE>/scripts/start-stop-status

look for a user name the package will sudo to, it mostly looks like this:

USER="couchpotatoserver" [..] su - ${USER}

create the user in the DSM GUI with the appropriate permissions

change the user have a shell (/bin/sh instead of /sbin/nologin) run the following command (replace couchpotatoserver with your user):

sudo /usr/bin/awk -i inplace -F: 'BEGIN{OFS=":"}/^couchpotatoserver\:/{gsub(/.*/,"/bin/sh",$7)}1' /etc/passwd

try again starting the package

this fixed the issues on all packages I ran into problems with.

Sadly the shell is being reset on each reboot, thats why I have shell script which runs this at every reboot:

#!/bin/bash # set the Login Shell for several package users to /bin/sh /usr/bin/awk -i inplace -F: 'BEGIN{OFS=":"}/^nzbget\:/{gsub(/.*/,"/bin/sh",$7)}1' /etc/passwd /usr/bin/awk -i inplace -F: 'BEGIN{OFS=":"}/^plex\:/{gsub(/.*/,"/bin/sh",$7)}1' /etc/passwd /usr/bin/awk -i inplace -F: 'BEGIN{OFS=":"}/^nzbdrone\:/{gsub(/.*/,"/bin/sh",$7)}1' /etc/passwd /usr/bin/awk -i inplace -F: 'BEGIN{OFS=":"}/^couchpotatoserver\:/{gsub(/.*/,"/bin/sh",$7)}1' /etc/passwd

I've put this script on my disk and run it as a triggered task every reboot. Triggered tasks can be setup in the DSM UI:

Control Panel

Task Scheduler

The DSM UI does not offer the estimation for raid parity checks/rebuild/rsync times. Luckily the information is available in the shell which is available via shell:

(look for finish= in the output)

$ cat /proc/mdstat Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] md4 : active raid1 sdd3[0] 483564544 blocks super 1.2 [1/1] [U] md3 : active raid6 sda6[0] sdf6[3] sdc6[2] sdb6[1] 1953485824 blocks super 1.2 level 6, 64k chunk, algorithm 2 [4/4] [UUUU] [=========>...........] resync = 49.0% (478876224/976742912) finish=2172.8min speed=3818K/sec md2 : active raid6 sda5[0] sdh5[6] sdg5[4] sdf5[3] sdc5[2] sdb5[1] 3887725824 blocks super 1.2 level 6, 64k chunk, algorithm 2 [6/5] [UUUUU_] resync=DELAYED md1 : active raid1 sdd2[6] sda2[0] sdb2[1] sdc2[2] sdf2[3] sdg2[4] sdh2[5] 2097088 blocks [8/7] [UUUUUUU_] md0 : active raid1 sdd1[6] sda1[0] sdb1[1] sdc1[2] sdf1[3] sdg1[4] sdh1[5] 2490176 blocks [8/7] [UUUUUUU_] unused devices: <none>

Speed up

Depending on the system-load the software raid rebuild/resync on a Synology is sometimes very slow.

It can be speed up by sacrificing some CPU & RAM by increasing the minimum-rebuild-speed and stripe-cache.

Normal 5.400rpm Disks can handle 100MB/s and this is what can be set as minimum speed as root user on the shell like this:

echo 100000 > /proc/sys/dev/raid/speed_limit_min

If you disk is slower or the system can't manage it, it won't matter it will still try to get to that speed but will stay slower.

Depending on the RAM size the raids stripe cache can be increased to improve performance too:

echo 16384 > /sys/block/md3/md/stripe_cache_size

If you have lots of memory, you can also try bigger numbers but 16k should suffice.

Slow down / Pause

Well, on the other hand, you can also slow the rebuild down to have it nearly paused. This might be useful if you want to use the disks while it is re-syncing without sacrificing speed.

echo 100 > /proc/sys/dev/raid/speed_limit_min echo 100 > /proc/sys/dev/raid/speed_limit_max

This will set such a slow speed limit, it will feel like a pause.

I recently bought a nice Synology DiskStation and one of the first thing that was missing is the right set of linux tools you are used too (watch, screen, lsof, git, etc.).

There's a simple fix for this, after enabling SSH access on the DSM GUI and connecting yourself to the server:

# become root sudo bash # download installer # example is for Intel Atom stations, check yours here: # http://www.synology-wiki.de/index.php/IPKG wget http://ipkg.nslu2-linux.org/feeds/optware/syno-i686/cross/unstable/syno-i686-bootstrap_1.2-7_i686.xsh -O installer.sh sh installer.sh # set search path for new binaries echo 'PATH="$PATH:/opt/bin:opt/sbin"' >> /root/.profile echo 'export PATH' >> /root/.profile # clear mount points and point them to your first volume umount /opt rmdir /opt ln -s /volume1/@optware /opt

uncomment everything in /etc/rc.local that it looks like this:

##!/bin/sh # ## Optware setup #[ -x /etc/rc.optware ] && /etc/rc.optware start # #exit 0

instead create a new startup script:

wget http://favo.s3.amazonaws.com/synology/optware.sh -O /usr/local/etc/rc.d/optware.sh chmod +x /usr/local/etc/rc.d/optware.sh

thats it!

with ipkg update and ipkg install <package> the power of linux is back in your hands!

I’ve just received my brand new FLY12 which serves as cycling light and “dashcam”.

I wanted to create some simple timelapse videos from the recordings and the following script is the result:

#!/bin/sh ID="$1" FILENAME="Lapse_$ID.mp4" SPEED="0.05" if [[ -z "$ID" ]]; then echo "missing id or path" echo "example: ./lapse.sh 2016-04-24 /Volumes/FLY12/DCIM/100_2016/0424*" else if [ -e "$FILENAME" ]; then rm "$FILENAME" fi ls -lrt -1 "${@:2}"|grep -v "thm\." > files.txt sed -i -e 's/^/file /' files.txt ffmpeg -safe 0 -hide_banner -v quiet -stats -f concat -i files.txt -preset veryfast -an -pix_fmt yuv420p -vcodec libx264 -crf 29 -filter:v "scale=-2:720:flags=lanczos, fps=fps=24, setpts=$SPEED*PTS" "$FILENAME" fi

The script is invoked with two parameters:

script.sh <id> <path>

It creates a simple text file with all the video files matching the PATH parameter and then calls upon ffmpeg to create a new video in 720p, 24fps with 20x speed.

It might also be interesting that an automatic youtube-upload could be added very easily with the sample script from Google Dev Docs.

My auto-upload looks like this:

I'm really lazy when it comes to do repetitive stuff, thats why I put these few lines together to automatically redeem all the currently valid passcodes for ingress I could find.

Just open the web console of your browser while being on the ingress intel map and copy & paste the following lines:

var codes = []; var oldCodes = []; function sendCode(code) { console.log("sending code " + code); document.getElementById('passcode').value = code; document.getElementById('submit').click(); console.log("var oldCodes = " + JSON.stringify(oldCodes) + ";"); console.log("var codes = " + JSON.stringify(codes) + ";"); setTimeout(function () { console.log(document.getElementById('redeem_reward_status').innerText); if ( document.getElementById('redeem_reward_status') && document.getElementById('redeem_reward_status').innerText.indexOf('too hot') > 0 ) { console.log("paused code sending for a while..."); setTimeout(nextCode, 60*30*1000); } else { setTimeout(nextCode, 10000+(Math.random()*5000)); } }, 15000); } function nextCode () { code = codes.shift(); if ( code ) { sendCode(code); } else { setTimeout(nextCode, 10000); } } function addCode (code) { code = String(code).replace(/[^a-zA-Z0-9]/g, '').toLowerCase().trim(); if ( code && codes.indexOf(code) === -1 && oldCodes.indexOf(code) !== -1 ) { codes.push(code); } else { console.log("invalid code or already known"); } } nextCode();

Then add whatever codes can be found on the internet by calling addCode in the console manually like this: addCode("ada3zc36qq9");

Repeat for all codes and it will try to redeem a code every few seconds.

Copy & paste this to use the codes I've found:
