- Adventurer & software developer.Information Technology and Services | Oslo Area, Norway, NOSummaryResumé: http://gyaresu.org/gareth_cv.txt
Currently seeking work freelancing or permanent in the capacity of project management, sysadmin, website builder, support monkey... other stuff.
Willing to relocate worldwide.
Sysadmin stuff:
I am experienced with provisioning and setting up websites on many systems. I grok dns, tcp/ip, apache, linux, cloud services (Heroku, AWS, Google App Engine, etc.).
I'm most at home on Debian based systems but can (and am) happy on RHEL/CentOS & others. Solaris is just a mystery and Windows Server makes me die a little on the inside.
I understand the OSI Model. That means I can build and troubleshoot computer networks. Which is why I can look for multiple servers doing DNS or a bizare static netmask once we've established your network is experiencing a "Should work, doesn't." moment.
I dig wireless protocols and encryption. I like security. I love the banned hosts in log files created when you try and brute force a network I built.
I like helping people with computers. I like translating difficult acronyms into human analogies. I like making computers more accessible.
I dig working with Open Source technology because apart from getting amazing tools for free they always teach me something. Usually it's why the output of one program won't work as the input to another but I love that with enough research you can find a way.
Languages: Python, JavaScript, Shell scripting, Perl (learning). (Generic not-really-language stuff: HTML, CSS, JSON, XML etc.)
I love working from my mobile office.
My gear:
Macbook Pro 2.66GHz Intel Quad Core i7
iPhone4S
3G internet 1Mb up / 500kb down
Current location until June 2012: Lovely wooden house overlooking the ocean, Goa, India.Specialties: Troubleshooting, Support, Networking, Project Management, Anything to do with setting up and supporting websites. Scuba diving.Experience- Oct 2011 - PresentAdventurer / Self Employed software developer.I currently work in a remote capacity as a freelance sysadmin. Linux based. Other than that I spend most of my day programming and learning. I'm building http://oslogigs.com as a real-world project and apparently I'm re-writing it every few weeks in a new framework, which is fun. I started with Google AppEngine and then re-wrote it to be a static site running with http://trigger.io and have now moved to a http://nodejs.org & http://parse.com data backend running on http://heroku.com How cool are these services! Great fun! I'm focusing on JavaScript & the ubiquity of web applications. I think there's something to be said about Atwood's Law: "Any application that can be written in JavaScript, will eventually be written in JavaScript." http://www.codinghorror.com/blog/2007/07/the-principle-of-least-power.html On the server side I am learning mostly Python but the libraries to Perl are awesome.

I've been teaching myself JavaScript and Python for the last six months and thought now was a good time to open up my private repository hosted on GitHub.
I've started with a fresh repo as my original private repo had too many keys & mess in it.
You can see the working version here http://oslogigs.com
It's a web app for finding the price of øl (beer) in pubs and venues around Oslo, Norway.
It uses a Google map with numbered markers.
I intend to continue on it and hopefully add http://twillio.com authentication via sms so that the site is fully automated for price updates.
So if you're in Oslo and find the price either missing or wrong, let me know.

...fixing current templating system...
Well I was.. Until I found out that my changes to the Jekyll template file weren't getting updated on http://gyaresu.github.com
So now I need to wade back into the Jekyll code and figure out what it actually does when it's generating the static content.
I mean, the local version works fine. It's only relying on the Github server to re-run the config and generate new static code from the templates based on the new config.
sigh
This was meant to be easier...

Installed the latest version of zsh via Macports.
Setup of oh-my-zsh involves cloning the Github repo, picking a theme and choosing which plugins to use.
oh-my-zsh automatically checks for updates and pulls new versions.
The plugins are excellent. Rails, git, OSX, hub, capistrano, brew, ant, macports, etc.
And zsh as usual is fantastic. Just use it to find out why.
You'll never want to go back to bash after using it.

I've been installing software and tweaking my main site via the iPhone today. I'm using a bunch of plugins for Wordpress and a couple of iPhone apps to assist me in controlling my content creation.
Mainly I just don't want to directly submit any more of my life through places like Facebook and Twitter where I don't even get to own it. I'm ok for now submitting still to these 'free' services but only until I figure out a complimentary system.
I got screwed by Apple today. Seems like my new laptop hadn't really shipped a week ago like they said. Apparently next week for sure! Muppets.
Till then only as many experiments as I can be bothered with on this little screen.
Don't even get me started on doing any real work via iPhone touch screen.
Time for an experiment!

I've been thinking a lot as usual about our future and the very different lives we lead as a result of technology.
We are not controlling our online lives. Just try accessing your old Facebook or Twitter posts.
Most people won't change their current ways until there's a reason to.
I endeavor to beat a path for others to follow. I know from the outset I'm not alone in this and I hope there will be critical mass to move away from these gilden cages.
p.s. Big shout out to future me! Flying cars yet?

So apart from becoming a diving instructor living in Airlie Beach and generally being warmer, nothing much has happened since my last post (Ha!).
I'm waiting for delivery of a nikon 35mm f1.8 lens (AU$299).
Said lens will give me a 52mm equivalent on my Nikon D80.
This will be one of the main projects for the foreseeable future.

DNS (Domain Name System) is one of those truly wonderful chunks of knowledge that you can get away with outsourcing but in the end you really need to know wtf is going on.
I have a soft spot for DNS. I know that I don't know enough and yet I know more than most.
It's a wonderful place to focus your knowledge. Especially with IPV6 coming along while gazzilions of admins around the world chant the chorus to "la la la la la la la la la la la la" with fingers firmly stuck in ears.
It's the glue of the internet. There really no way around it.
You may drive one of a thousand cars on the internet highway. TCP/UDP implementations of JSON/HTML/XML/SQL/BLAHBLAHBLAH but DNS tells everyone where to go.
Here's to you DNS. WIth your spoofing and your new found vulns you still rock my world.
Tip of the Hat!

Well I'm still living out of a backpack and the ideas of what to do with my life are starting to mount up.
What a strange position to be in. I have a couple of businesses that tick over and only require me to work from the interwebs. So now I'm physically free but can't decide where it is I should put my person.
Peru and their AU$130/month iphone plans with unlimited data?
Australia in a campervan?
London and Linux sysadmin?
Well I was quite looking forward to Amsterdam and Greenpeace sysadmin but UK Passport office helpline for passports #fail means UK passport in 12 months. I'll have another chat with Greenpeace then perhaps.
What to do till then?
Christof Rehage has an amazing youtube clip that is a must-see http://www.thelongestway.com
That's given me the inspiration to think about walking up the eastern seaboard of Australia. I could work and walk, losing some desperately unwanted kilos.
Will walking be so much different to driving. I know the coastal route of Australia pretty well in that lazy hop-to-hop next-pretty-place kind of way. Have laptop will travel?
Do I need to get a cart built? What about charging camera/laptop/iphone?
Should I be doing this in Europe, South America, China, South East Asia?
Buggered if I know. Maybe something positive to do with the Copenhagen Climate summit?
Just starting to walk could be a good idea.

Changing the media type to audiobook:
iPod on my iPhone 3G was removing the audiobooks I was listening to at strange times. On sync or even just plugging in the power. So a little research found that with iTunes 8 you can select a Genre then 'cmd + a' >> right click >> options and change "Media Kind" to "Audiobook". Tick "Remember Position" and "Skip when shuffling" >> Ok.
Sorted.
Next problem was having upgraded my drive to a 500GB 7200RPM Seagate (465GB irl) the Time Machine was showing insufficent space on the external 500GB drive as it needed to backup 469GB.
Problem is that there's only 390GB on the laptop drive. Hmmm. The internets doesn't seem to want to help on this one either.
Solution:
Under "Options" on the Time Machine preferences panel you can click the wee "+" button and add folders or even entire drives that you don't want TM to backup. What I discovered was that TM isn't really sure how much stuff you have on your internal drive until it has a crack at it. Problem is it also adds a 20% buffer to its estimation. What needed to be done was add almost all of the large folders (Applications, Users) and let it have a go at backing up the few remaining ones first. This done you go back and remove all the other folders from "Do not back up:" and let it run again. Voilá!

Well apart from a dismal rushed attempt to write a resumé in 2002 I've gotten along just fine without needing one.
The time has come though where some of the interesting jobs I want to apply for are on the other side of the world and there's no chance to look them in the eye and shake their hand.
So...
Research. I've done the http://delicious.com search and found a great Rands piece http://www.randsinrepose.com/archives/2007/02/25/a_glimpse_and_a_hook.html
There's a pile of good examples here: http://jobmob.co.il/blog/beautiful-resume-ideas-that-work/
So. Best get to it.
EDIT: The funny and talented Zed Shaw http://zedshaw.com/ offered his resumé template and build system in TeX.
It draws on using pygments and idiopidae to do the syntax highlighting. You then use vellum to build it. Plus use tetex not latex.
How awesomely geeky is that for doing a resumé.
I really really appreciate it when people go out of their way to help others.
I better go do some duty in the IRC rooms now :)

Hi Matt.
I've held off a month before writing you this email because I didn't want it to come across as a personal attack.
One of the reasons I initially chose to go with Bluehost was because of your excellent blog.
Unfortunately there's nothing that can change the way I feel now when someone mentions your company (please note again, not a personal attack).
Around the 19th March 2009 my bluehost account giantfriend.com was closed and all data deleted without warning or even explanation.
Bluehost had always been my main hosting site (around 14 websites) and I have a server in Sydney (I'm in Australia) for latency important sites.
This is my business and of course all of my clients relied on DNS email & site hosting from me.
I spent the next week after this catastrophe attempting to get the account reinstated and all the sites back.
Although the bluehost staff are friendly and helpful there was no-one who could tell me what the problem was that caused account deletion and no-one could retrieve any backups at all.
I have no idea if this was a violation of the terms or a mistake or an overzealous sysadmin. My entire account was just 'gone'.
Needless to say I was absolutely gutted and don't need to tell you that there should have been some measures in place to protect from this now apparent 'Sword of Damocles'.
To the best of my knowledge the account was using ~5GB of data & serving up pretty standard php/mysql based websites. There was no file sharing or dodgy content on the server.
I include the first email I received as none of the subsequent emails or phone calls provided any more clarity:
Dear Gareth: Your web hosting account for giantfriend.com has been deactivated (reason: call customer support). Although your web site has been disabled, your data may still be available for up to 15 days, after which it will be deleted. If you feel this deactivation is in error, please contact customer support as soon as possible. Thank you, BlueHost.Com Support http://www.bluehost.com For support go to http://helpdesk.bluehost.com/ Toll-Free: (888) 401-4678 Please feel free to contact me if you have any questions. - May 10, 09

Say you've got your webserver listening on port 80 and all requests from your router for webpages point to it (server0).
Now say that server0 handles Name based Virtual Hosts. So the one Apache web server is hosting a whole bunch of domains: example.com example2.com example3.com etc.
What do you do if you want to run a second server (server1)on the same IP address?
Well you could have another server there just to load balance or you could get the router to do it (if it was smart enough).
But another way is to setup server0 to proxy connections of your choice over to server1.
/etc/apache2/mods-enabled/proxy.conf
ProxyPreserveHost On ProxyPass / http://192.168.1.9 ProxyPassReverse / http://192.168.1.9 ServerName example.com
Server1 has Name based Virtual Hosts as well and doesn't need any special configuration.

Make sure that iTunes is not running on both Macs. Disconnect your iPhone/iPod from both Macs. Copy your iTunes folder. /Users/username/Music/iTunes Copy your iPhone/iPod backups. /Users/username/Library/Application Support/MobileSync Copy your iTunes configuration files. /Users/username/Library/Preferences/com.apple.iTunes* Open iTunes on your new Mac and verify that Applications and Ringtones appear. Connect your iPhone/iPod to the new Mac and accept any new authorizations. Use iTunes on your old Mac to de-authorize the computer.

"It's not surprising, therefore, that projects tended to be behind schedule. Take a plan that's created according to a generic formula, estimate the work in advance of any significant knowledge of requirements, have the estimates done by people who won't be doing the work, never update the plan after work is started, and what do you get? Lousy plans... and they were treated as unquestionable truths."

The reason you have to use dpkg --force-confmiss is because whenever your config files () are gone, dpkg assumes you deleted them on purpose, and that you want them to stay deleted. You can also reinstall them using the following apt-get line: apt-get -o DPkg::Options::="--force-confmiss" --reinstall install ; or using aptitude, aptitude -o DPkg::Options::="--force-confmiss" reinstall ;

So set the systemwide python to be python2.4.
This is a note to self when everything else breaks from using the old version.
cd /usr/bin sudo rm python sudo ln -s python2.4 ./python
EDIT: That fraked all sorts of things. Looks like hellanzb from the cli for now.

So new house only has phone line in the kitchen. Solution: WDS using Tomato of course.
So now I have one wrt54g connecting to the net in PPPOE Bridge mode with a billion modem (meh, average modems).
And one wrt54g in my office that acts as an extension of the main one. So plug that into a switch and all the computers here in the office can connect via ethernet.
One more for the lounge and the movie/music server and I'm sorted.

So I tried the 8800GT 512MB to see whether crysis would run 'aight. No go.
Anyway, while messing around with the card under linux I upgraded the nvidia drivers to the latest from the nvidia site (ubuntu doesn't have them in the repos yet).
My stupid second monitor couldn't have its stats detected (edid).
So off I go AGAIN fsck'ing around with xorg.conf and Xorg.0.log files to figure out what's changed THIS driver release.
Anyway: The Error
root@sdf:~/x11# cat /var/log/Xorg.0.log.old |grep -i edid (WW) NVIDIA(GPU-0): Unable to read EDID for display device DFP-1 (--) NVIDIA(0): DPI set to (90, 88); computed from "UseEdidDpi" X config
The Fix (get the edid.bin from the one working monitor under nvidia-settings, look in the GPU settings. You can save it from there.)
Section "Screen" Identifier "Screen0" Device "Videocard0" Monitor "Monitor0" DefaultDepth 24 Option "TwinView" "1" Option "CustomEDID" "DFP-1:/home/gyaresu/edid.bin" Option "RenderAccel" "true" Option "metamodes" "DFP-0: nvidia-auto-select +1680+0, DFP-1: nvidia-auto-select +0+0; DFP-0: 1680x1050 +0+0, DFP-1: NULL" EndSection The result:

Browser.tabs.tabMinWidth is the Firefox configuration value that determines the tab width. Here is how to disable tab scrolling:
- Type about:config into the Firefox address bar.
- Find the browser.tabs.tabMinWidth key. The default value is 100.
- To disable tab scrolling completely, double click on it, set the value to 0. To make more tabs fit before scrolling gets activated, set that number to 75.

Have guests write their name on a quart-size Ziploc freezer bag with permanent marker. Crack 2 eggs (large or extra-large) into the bag (not more than 2) shake to combine them. Put out a variety of ingredients such as: cheeses, ham, onion, green pepper, tomato, hash browns, salsa, etc. Each guest adds prepared ingredients of choice to their bag and shake. Make sure to get the air out of the bag and zip it up. Place the bags into rolling, boiling water for exactly 13 minutes. You can usually cook 6-8 omelets in a large pot. For more, make another pot of boiling water. Open the bags and the omlette will roll out easily. Be prepared for everyone to be amazed. Nice to serve with fresh fruit and coffee cake; everyone gets involved in the process and a great conversation piece.
Imagine having these ready the night before, and putting the bag in boiling water while you get ready. And in 13 minutes, you got a nice omlette for a quick breakfast!!!
I used tomatoes, ham, green onions, cheddar cheese and mushrooms in this one! MMMMMMMM . . .MMMMMMM good!!!"

I run MPD as my music player because it's FREAKING AWESOME. It's a daemon so you can basically connect to it any way you want: command line interface ncmpc or via your browser with Pitchfork or a GUI like Sonata.
Of course one needs one's Last.FM submissions and fortunately MPDScribble does the job.
<edit: 2008/08/07>
I'm now using Mint Linux (currently the most useable debian based Linux imho) and MPDScribble is fubar for some unknown reason (I've spent days looking at it). So instead installed lastfmsubmitd to submit to last.fm & lastmp to get the info from mpd. They've both got lovely ncurses setup screens that asks your lastfm name/password & what group you want to run the daemon under. Brilliant.
http://www.red-bean.com/~decklin/software/lastfmsubmitd/
So today I tweaked the mpd.conf to output to multiple audio streams. One to my awesome NAD C 320BEE amp & Quad 22L's, and the other to my server running icecast2.
So now I can login to my server http://LikeI'mGoingToTellYou.org/mpd/ to access Pitchfork & http://LikeI'mGoingToTellYou.org:8000 to grab the stream.
All I have to do is grab foobar2000 and I can now listen to all of my rather extensive music collection from anywhere in the world.
It's like taking home with me everywhere I go. Sigh I feel all gooey on the inside.

Source: http://www.linuxtutorialblog.com/post/tutorial-playing-around-with-mplayer
This tutorial handles about the usage of the wonderful media player MPlayer. It explains several options, lists some useful keyboard shortcuts and handles about tips and tricks that can be used to enhance your multimedia experience.
Difficulty: Basic
Note: this tutorial assumes that you have MPlayer installed & working and that you have some basic shell knowledge.
Playing a file
The most simple way of invoking MPlayer to play a media file is this:
[rechosen@localhost ~]$ mplayer
MPlayer will try to auto-detect what kind of file you're trying to play (it usually succeeds) and play it. If it's an audio file, it'll just start playing and show its status and possible warnings on the command-line. If it's a video file, it'll open a window to play it in and then start playing.
Seeking through a file
You can seek through a file with a set of 3 keyboard shortcut pairs. Each pair makes MPlayer seek a different amount of time, and the pair consists of a key for seeking backward and a one for seeking forward. Listed below are those key pairs, for seeking backward and forward respectively: Left arrow and Right arrow (10 seconds) Down arrow and Up arrow (1 minute) Page down and Page up (10 minutes)
Knowing these will come in handy a lot of times.
Playing a DVD
MPlayer does not have DVD menu support (sadly), but it does support playing DVD's. You can play a DVD this way:
mplayer dvd://
Replace with a number, like 1, 2 or 3. I personally prefer xine for DVD playback, as xine does support DVD menus.
Playing with subtitles
You can play a movie with subtitles in multiple ways. When playing a movie file, you can specify a subtitle file this way:
[rechosen@localhost ~]$ mplayer -sub
When playing a DVD movie, you can also use the DVD's subtitle by specifying a language code like this:
[rechosen@localhost ~]$ mplayer dvd:// -slang nl,en
The above command would try to use dutch subtitles first, and fall back on english ones if dutch subtitles weren't available.
Useful keyboard shortcuts
A list of useful keyboard shortcuts (sometimes called hotkeys) in MPlayer:
(note that the full list can be found in MPlayer's man page) "f" => Toggle between full-screen and windowed mode during video playback (you can set the option -fs on the command line to make MPlayer start playing in full-screen mode immediately) "o" => Switch OSD (OnScreen Display) mode during video playback (for viewing how much time the movie has been playing and what its total lenght is) "p" or Space => Pause / resume playback "q" or Esc => Quit MPlayer (Esc does not quit but only stops playback when in GUI mode) "/" and "" (or "9" and "0") => Decrease / increase playback volume respectively "m" => Mute sound (toggle) "T" (usually Shift + "t") => Toggle stay-on-top (very useful if you don't want your video window to be overlapped by an other application) "b" and "j" => Cycle through available subtitles "x" and "z" => Adjust subtitle delay (useful if you have a subtitle that isn't 100% synced; you can then correct the time difference on the fly) "I" (usually Shift + "i") => Show the filename of the movie being played (useful if you want to know that without interrupting the movie) "1" and "2" => Adjust contrast "3" and "4" => Adjust brightness "5" and "6" => Adjust hue "7" and "8" => Adjust saturation*
*: These do not always work; see the MPlayer man page.
Generating an index
Sometimes, video files (mainly AVI files) have a corrupted index, or no index at all. This frequently is the case with incorrectly or incompletely downloaded files. Fortunately, MPlayer can generate the index it needs to play the file correctly. By using the -idx option, you can tell MPlayer to generate an index when necessary:
[rechosen@localhost ~]$ mplayer -idx Sometimes the file does contain an index, but a corrupted one. In those cases, you might need to force MPlayer to generate an index:
[rechosen@localhost ~]$ mplayer -forceidx
Generating an index can take some time, depending on the size of the video file, but after that, the file should play correctly.
Correcting bad audio/video sync
Some videos (mainly flv files) are encoded in a horrible way, and MPlayer will have enormous trouble with the A/V (Audio/Video) sync. There are pretty much two possibilities in this case: MPlayer is trying to fix it but the sync is worsening too fast MPlayer is trying to fix something that's already right and therefore pushes the sync away unnecessarily
In the first case, you should allow MPlayer to try harder to fix the sync:
[rechosen@localhost ~]$ mplayer -autosync 30 -mc 2.0
In the second case, you shouldn't allow MPlayer to fix anything when it comes to the sync:
[rechosen@localhost ~]$ mplayer -autosync 0 -mc 0
You might wonder what those options mean. Well, setting autosync to a positive value allows MPlayer to gradually adapt its A/V correction algorithm. The higher the value, the faster MPlayer will try to correct it. The mc option specifies how many seconds MPlayer may correct every frame. Setting it to a high value (like 2.0) practically allows MPlayer to do whatever it thinks it should to correct the A/V sync. Setting it to 0 stops MPlayer from trying anything when it comes to syncing.
Using MPlayer on slow systems
As video playback is a CPU-intensive task, older and slower systems may have a hard time to play certain video files. MPlayer has a feature that will help them to keep up the playback with less CPU power: -framedrop. This will allow MPlayer not to render a frame here and there if the CPU can't handle it. On systems that are far too slow, it won't be a pleasure to "watch" the movie (the majority of the frames will just not be rendered at all), but on systems that are a bit faster, this will stop the playback from having hiccups here and there. You can use the -framedrop option like this:
[rechosen@localhost ~]$ mplayer -framedrop
Also, when trying to play MP3 or OGG Vorbis files, you might (on really slow systems) experience buffer underruns, spoiling your music experience. In that case, try using the libmad (in the case of an MP3) or the Tremor (in case of an OGG Vorbis) audio codec. You can detect whether you have a one or not like this:
(In case of MP3)
[rechosen@localhost ~]$ mplayer -ac help | grep mad If the above command returns a line like this:
mad libmad working libMAD MPEG layer 1-2-3 [libmad] Then you can play an MP3 file with libmad, which uses a lot less CPU power. To do so, invoke MPlayer like this:
[rechosen@localhost ~]$ mplayer -ac mad In OGG's case, you can use the same trick to look if you have a tremor audio codec available:
[rechosen@localhost ~]$ mplayer -ac help | grep tremor
Sadly, I don't have an example of what it should look like. If you seem to have a working tremor decoder, please leave a comment here so I can add it.
Playing streams from the internet
Many web radio stations make you download a playlist with different ip's and ports if you want to listen to them. MPlayer is perfectly able to play a web station stream, but the playlist is not a stream, nor a media file. If MPlayer doesn't autodetect that it's looking at a playlist and not at a direct stream or media file, you can try using the -playlist option:
[rechosen@localhost ~]$ mplayer -playlist And if the server has hiccups and causes a lot of buffer underruns (or if you have a bad connection), you can set a bigger cache size:
[rechosen@localhost ~]$ mplayer -cache 8192 -playlist The cache size is specified in kilobytes; the above will make MPlayer use a cache of 8 mb. Note that MPlayer doesn't fill the whole cache before it starts playing, it only fills about 4 percent (after that it'll try to keep filling the cache during playback). You can alter that percentage with the -cache-min option:
[rechosen@localhost ~]$ mplayer -cache 8192 -cache-min 50 -playlist
You can seek in a cache, but do not expect too much of it =).
Looping playback
If you want the media file you're playing to loop a certain amount of times (or infinitely), you can specify the -loop option, like this:
[rechosen@localhost ~]$ mplayer -loop 3 The above command will play three times and then exit.
[rechosen@localhost ~]$ mplayer -loop 0
The above command will repeat playing forever, unless it is interrupted (for example by quitting MPlayer with the "q" keyboard shortcut). Infinite playback can be useful if you, for example, want a (promotion) movie to play all day on an exhibition.
Altering the playback speed
This may not be that useful, but it can be good for a laugh =). You can make MPlayer play a media file at a different speed with the -speed option. The value 1.0 means normal speed, 0.5 means twice as slow, 2.0 means twice as fast and so on. Specify the option like this:
[rechosen@localhost ~]$ mplayer -speed 2.0
Altering the sample rate
You might want to alter the output sample rate sometimes (certain audio cards, for example, do not support other samplerates than, say, 48000 Hz). This is done with the -srate option, like this:
[rechosen@localhost ~]$ mplayer -srate 48000
This can also be useful when exporting audio to a file (see next chapter).
Exporting the audio to a wav file
You can export the audio of a video file to a wav file this way (note that you can also use this to convert an audio file to a wav file):
[rechosen@localhost ~]$ mplayer -ao pcm This will export the audio to the file audiodump.wav. You can also specify a filename for the exported wav:
[rechosen@localhost ~]$ mplayer -ao pcm:file=.wav
Watching a movie in ASCII
Another pretty useless but funny feature. There are two libraries that provide support for this: aa and caca. With libaa, you can only watch a movie in black & white ASCII, while libcaca supports colors. However, libaa is more widely supported. You can watch a movie with libaa this way:
[rechosen@localhost ~]$ mplayer -vo aa And, if you want to (and can) use libcaca:
[rechosen@localhost ~]$ mplayer -vo caca
Exporting a movie to a lot of pictures
MPlayer can also export a movie to a load of images. For example:
[rechosen@localhost ~]$ mplayer -vo jpeg
Warning: the above command will output a huge amount of jpeg files. I strongly recommend to do this in a freshly made, empty directory created for this purpose.
The filenames of the jpeg file it will export will look like this: 00000001.jpg 00000002.jpg 00000003.jpg And so on... You can export to some other formats. Just replace jpeg in the command above with ppm, png or tga. Note that all these image format have their own options, too. Look for them in MPlayer's man page.
Specifying an aspect ratio
When playing video files on, for example, a wide laptop screen, you'll probably want to benefit from that wideness by watching a movie in a 16:9 aspect ratio. You can do that this way:
[rechosen@localhost ~]$ mplayer -aspect 16:9
Of course, you can also specify 4:3 as the ratio to force MPlayer to show the movie in non widescreen format.
Putting options in your MPlayer config file
MPlayer has a nice way of storing options so they will be automatically set every time you invoke the MPlayer command. This can be useful if your system, for example, always needs the audio outputted with a different samplerate. However, the syntax of the config file is a little different. If you'd type -srate 48000 on the command-line, this should be specified in the config file as srate=48000. More complex options, like the -ao pcm:file=.wav, should be put between quotes in a way like this: ao="pcm:file=.wav". The config file is located at ~/.mplayer/config for a user, and a global configuration file is located at /etc/mplayer/config. The different values are separated by newlines, like this:
MPlayer config file
srate=48000 ao="pcm:file=dumpedaudio.wav"

Your aim
You want to use Linux and OpenSSH to automize your tasks. Therefore you need an automatic login from host A / user b to Host B / user b. You don't want to enter any passwords, because you want to call ssh from a within a shell script. How to do it
First log in on A as user a and generate a pair of authentication keys. Do not enter a passphrase: a@A:~> ssh-keygen -t rsa Generating public/private rsa key pair. Enter file in which to save the key (/home/a/.ssh/id_rsa): Created directory '/home/a/.ssh'. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/a/.ssh/id_rsa. Your public key has been saved in /home/a/.ssh/id_rsa.pub. The key fingerprint is: 3e:4f:05:79:3a:9f:96:7c:3b:ad:e9:58:37:bc:37:e4 a@A
Now use ssh to create a directory ~/.ssh as user b on B. (The directory may already exist, which is fine): a@A:~> ssh b@localhost mkdir -p .ssh b@localhost's password:
Finally append a's new public key to b@B:.ssh/authorized_keys and enter b's password one last time: a@A:~> cat .ssh/id_rsa.pub | ssh b@B 'cat >> .ssh/authorized_keys' b@B's password:
From now on you can log into B as b from A as a without password: a@A:~> ssh b@B hostname B
