MPD's little helpers
I use MPD + ncmpcpp and its really awesome. I use mpdscribble for scrobbling to last.fm and mpd-sima for adding common songs in the playlists, and other tools like mpd-add-similar look nice (adding more than one song at a time.). What i miss now is a simple last.fm love track script or something, and a script that will copy the songs from a mpd playlist to a mp3 player. Anyone mind sharing such scripts or helping me make one ? , plus if you have any idea or a nice mpd tool write it here

loving a track:
http://aur.archlinux.org/packages.php?ID=41508
how I use it:
> cat love
#!/bin/bash
~/bin/lastfm-mpd-cli.py love --lastfmusername=USER --lastfmpassword=MD5SUM_OF_PASSWORD && echo "You loved `mpc current`" | dzen2 -y 1062 -p 4 -fn envy-code-r-10 -fg '#00BBFF' -bg '#080808'
just put ~/bin/love to some hotkey - voila
thanks alot , it works as a charm.

What's a good desktop environment/general system UI for a television?
So right now I just upgraded to Arch (without planning to do so, but that's another story) on my media station, and I'm trying to figure out what desktop environment to use with it. It is hooked up to an old analog TV as the only display (I do most of my configuration via ssh and the command line), and my wife (who's not a Linux user by any stretch) uses it a lot.
I'm finding Gnome 3 (since it had Gnome on it before I just went with that) is really not suited to this purpose. It seems to want things like a higher resolution than what can be readable easily on the TV, and if I set it to a lower resolution setting menus will get pushed off the screen. I also prefer something where I can do all the configuration from the command line, because I'm usually going to be configuring it remotely.
What the media station does normally is play videos in VLC (either saved video files or DVDs), play YouTube videos in a browser, and move around and delete files on the desktop with a mouse. The way the keyboard is set up it's hard to use as well. So I'm wanting something that makes all of those really simple with the constraints of a low resolution TV, and avoids needing the keyboard if at all possible.
Any suggestions?
Bonus points if people can come up with a way that someone can easily move around and delete the files from a browser on a Windows machine, as that's what my wife has with her a lot when she's sitting at the couch. She doesn't want to install anything on that computer or use things like Windows filesharing though.LXDE isn't optimal if CLI configuration matters to you... but does this really matter if you expect to set it up once and be done with it?
Openbox' XML syntax is needlessly annoying if you don't want to use the optional GUIs or other little helpers, I'd go with a simple window manager rather than a DE.
Fluxbox is easy, text-friendly and doesn't require a DE on top to meet modern expectations. Personally, I think a well-tweaked FVWM beats the pants off anything else.
Nevertheless, debugging the wife seems to be a higher priority for now... with good suggestions already. -
How to save my emails and adressbook files from an old ibook?
How to save my emails and adressbook files from an old ibook (bought around 2002) ?
The screen from the old ibook doesn´t work anymore (logicboard problem I guess).
I saved everything else with starting it in target modus. That worked fine.
I want to delete the files after that as well, because I wanna give away the old ibook and don´t want anyone to read my emails!
Little helpers I have:
A running MacBook
External Screen (and cables to connect)
Fire Wire CableDon't know how helpful this will be but I often copy mail from one computer to another, I drag the mail from the mail window to the other computers drop box, then from the other computer double click it and mail asks me what I want to do with it, of course without a screen you'd need to use back to my mac.
If you don't have back to my mac running, you could set up a second user account on the newer mac, import everything via target mode as suggested by c above, and then drag the mail to the first user account drop box. -
iPhoto has somehow uninstalled itself, or I've done something wrong. If I try to open iPhoto, it gives me this message: "You can't open the application "iPhoto" because it may be damaged or incomplete". I have an iMac OS X. How do I reinstall iPhoto please?
What is your iPhoto version and how did you install it originally?
If it came with a new mac and Lion or Mt. Lion installed, you can delete iPhoto from the Applications folder (don't empty the Trash) and download it again from the "Purchased" tab of the App Store.
If you have bought the iLife CD, reinstall iPhoto from the installation media, after deleting it from the Application folder.
Or if your Mac came with an older MacOS X, but iLIfe preinstalled, use the system Install CDs, see Terence Devlin's post here: Re: My iPhoto isn't working. Error message says "you can't open the app "iPhoto" because it may be damaged or incomplete.
Regards
Léonie
P.S: This may not only be a problem of a broken iPhoto. What did you do, directly before this happened? Did you run a program, that will clean the Mac to save space, like "Clean My Mac" or "Mac Keeper"? These little helpers can be risky and overdo it and remove too much. Then it might be safer to reinstall your system, because other essential files might be missing now. -
How to view first page of newsletter (Publisher file convert to ?)
I am using Dreamweaver CS4 on a Mac. I am trying to post the first page of our newsletter on the page. See http://indianaeagleforum.org/newsletter.htm Here it is FrontPage 2002 and the newsletter was done in Publisher 2007. I am redoing the website in Dreamweaver. I can save the Publisher file as a .jpg but then the page is too wide. It saves as 1276 px wide and the web site is 955 px wide. In FrontPage I can specify the width and still keep the correct aspect ration and it will shrink the page. What should I do in Dreamweaver? I can save the Publisher file as a .tif or.png or as .html. I am afraid the .png file would not print well. What would you suggest? Thank you.
Dear Diana,
never quit, please!I quote: ... the file is too big and takes too long to load ...
If you really want to follow our recommendations, there are still plenty of opportunities to "optimize", resize (by using compression techniques), correct, cut, aso. all your images for the web.
Very good "little helpers" you will find in Photoshop, Fireworks, Microsoft Office Picture Manager, MS Photo Editor aso. Perhaps you work with all of them already or you know them at least, so the application should not be a problem.
"Microsoft Office Picture Manager" as an element of "Home and students" I prefer if it's necessary to convert multiple images at once in different sizes.
Phew, a long load time is not a must now, or!?Hans-G. -
Convert path line to polyline?
Hello,
anyone here know it's it's possible to convert a path into a polyline?
I need to save SVG (but polyline, not path)
Many thanks!
r.Hi
this is not the best way to do that, but all you need to do it better is inside this stuff (i hope).
have a look at the examples at the bottom.
cheers chris

IWeb, Joomla, Expression Web 2.0...sooooo confused
Hi all,
First I am new to website development...king of the newbies I had my website done and the guy used Joomla (open source). So I have been playing with it and it seems pretty straightforward. I then had lunch with a friend and he said he did his in iWeb. I googled iWeb reviews and saw it was criticised because it made sites that were not very searchable. I am going to create a web site for another business and it needs to be searchable...highly searchable (or rather the ability to make it that way via coding, etc...).
My question is can iWeb be made more searchable by spiders, etc...? Also, my friend got an extra copy of MicroSoft Expressions Web 2.0 for his birthday and doesn't need it. He has offered to sell it to me for peanuts. Should I just go with that (I work on both PCs and MAC) and forget about iWeb or Joomla?
Thanks in advanceJoomla is a content management system running on the server. It is operating system indipendent (does not matter if you are using win or osX).
But your server has to support php and mysql.
If you are a web development noob as you say, I would stick with iweb, it is a breeze to use.
If you want to dig a little deeper in webdesign check out joomla (it is free). It is a great and extremely powerful content management system (CMS)!
The concept of joomla (and any other CMS) is to divide content from design. So whenever you want to give your site a different look you simply change the so called template. All your texts, galleries etc. stay untouched as they are stored in a sql database. Only the layout and colors will change.
Many web space providers offer one click installations of joomla, so getting started is not that hard.
As development environment I recommend aptana studio (also free).
It can be seen as the oposit to iweb since it is a pure code environment but has many little helpers making it easy to edit Html java script and so on templates.
It offers explenations for all commands in a website code and has extensive auto completion faetures that offer you possibilities for the next command.
check it out, but make shure to learn the basics of html first, else it will be very frustrating.

I hope this helps. -
Mail 6.0 has duplicate "On My Mac" folder structures
Having upgraded to ML 10.8 this morning I notice that Mail has two "On My Mac" folder structures below Archive, one is immediately below Archive (i.e. the top of the sub-tree) let's call it 1st instance, followed by iCloud, then the 2nd instance of an "On My Mac" folder structure.
From the erratic behaviour of the disclosure triangles in the 1st, this would appear to be the unwanted child. Click its triangle and the 2nd structure opens.
Now click the Archive disclosure triangle twice, once to close it all up, the 2nd click gives both "On My Mac" structures open to the first level, iCloud is unaffected. Repeat this operation and both "On My Mac" structures are closed up.
If you do open a sub-folder in the 1st instance, any subsequent click of the triangle is ignored, even in the other instance.
The 2nd instance is completely consistent in operation as would be expected under normal circumstances.
Closing and reopening Mail just remembers the current expanded state, the only consistent reset is achieved with the Archive close/open double manoeuvre.
Message was edited by: additall
Hmm, this was happening back in 2007, but the drag it out and back solution doesn't seem to work this timeUpdate, I think I've solved it for myself.
Previously, I had created a local folder called Archive. iCloud also comes with a default folder called Archive and Mail 6.0 was showing my local archive and combining it with its iCloud version, rather like the way that calendars and contacts get doubled up when your local stuff is mirrored on iCloud.
Having taken a backup of my local archive I trashed the lot, everything from the 2nd "On My Mac" tree downwards and then the other two sibling trees, the 1st "On My Mac" and "iCloud" just disappeared as well.
So my recommendation is don't use "Archive" as a local folder name.
I later created a test folder called "Local" and selected its location as "On My Mac". "On My Mac" is now listed in capitals, in a lighter grey colour, with the Hide/Show popup choice to its right. This is your local storage area, away from iCloud and Apple's little helpers :-) -
Preview - Remember Window Position
If I move my finder window, resize it, then close the window Mac OS X remembers this position and next time I open a finder window it opens to that position and size. How can I do the same with Preview?
that is really a missing feature and there are still many apps, that do not remember window size/position.
There are 2 little helpers available (and some others, this I have tested with 10.6), that at least reduce the extra effort to just pressing a keyboard shortcut, to move/resize the frontmost window.
In your case, it would so be possible to move/resize the Preview window to the right half of the screen.
--- ShiftIt: the totally free one:
http://code.google.com/p/shiftit/
it goes to the menu bar and does not have a dock icon.
It moves/resize to the 4 quarter screen's, the 4 half screen's and has maximize and center

Desktop apps developing: where to start
Hi!
I wanna develop some nifty little helpers doing common daily stuff, like checking the up time of the internet connection and displaying it anywhere on the desktop or in the gnome-panel. that's just an example. a lot of this tasks can be done with cronjobs and bash-scripts, but for graphical stuff there's somethin' else needed.
The question: Where to start? I know, a forum search and googling brings up a lot of tutorials, but I even don't have a point where to start, which programming language is best for apps like this.
And no, I'm not looking for general programming tutorials.
Thanks in advice!Well there's plethora of ways you can do build desktop apps. The language is mostly irrelevant nowadays, choose whichever you prefer, C, C++, C#, python, perl, tcl. You may start with deciding on language and possibly toolkint you would wish to use. Some hints, using C you have GTK as your primary toolking, then goes GNUstep thing, Xlib as an option if you need sort of hackish feeling, Motif if you have access to libraries and some ancient Unix system. If you would prefer C++, there's Qt (excellent documentation on http://doc.trolltech.com) and GTKmm. I personally prefer Qt since it's easy, intuitive and is a base of KDE.
You may end up using python which, surprisingly, seems to be preferred by most of people on the forums. If so then pygtk or pyqt is a must.
I would discourage from using horrid toolkits like wxWidgets, no fun at all.
Other thing for desktop apps would be inter-app communication and sharing common functionality, which is handled by Kparts & DCOP for KDE3, and (correct me if I'm wrong) bonobo - a CORBA-like thing for gnome (?).
For KDE these will be useful:
http://developer.kde.org/documentation/
API reference
http://developer.kde.org/documentation/library/
Both Qt and GTKmm have nice tutorial which help you get started quite easily.
However if you would like to write conky like stuff, then unfortunately Xlib is the way:

Some common desktop standards (system tray, iccm window manager etc.) are provided here:

Hi guys,
I'm looking at putting a few pdf's on my website and I've seen other sites with a link to pdf download to help people download it. Is there an official place to get this or if not will I have to make one?
Thanks for your help,
NathanHello Nathan,
in this cases I prefer to insert small photos from the several first pages as a thumbnail (you can use a gallery too). From there you should link to your different pdf-files.
Very good "little helpers" to creat the first page you will find in Photoshop, Fireworks, Microsoft Office Picture Manager, MS Photo Editor aso. Perhaps you work with all of them already or you know them at least, so the application should be no problem.
Good luck!

Helpful Linux Bash Scripts for I.T. Admins
I was wondering if you guys had any recommendations for helpful / simple Bash scripts that do helpful tasks in regards to Linux system administration? I have never created or used a Bash shell script but know that many of you guys do. I have no programming experience what so ever so decided to ask if you guys do have one or few scripts that are useful in basic administration tasks, could you please post them or at least point someone who is interested in the right direction?
Thank you so much!I'm no sysadmin but one were to use command-line a lot i would give ZSH a shot. A nicely configured zsh shell can be unbelievably comfortable and is certainly a great tool.
As for scripts I always thought of them as little helpers customized for certain situations. For instance easing repetitive tasks, batching some steps and timing/automating little things. For general purpose I'd probably look at available software first.
Maybe tmux for terminal management, ranger for file management, a tiling window manager for efficiency, ssh and other survaillance/maintenance software? Personally, I'd very much like to hear, too, what software/scripts/.. linux systems admins use to keep the work to a minimum . -

If the songs were purchased from itunes, I suggest that you delete the tracks from your itunes library and move to trash (providing you live in a country that permits redownloading). See http://support.apple.com/kb/PH12283.

Some help please navigating these forums and a little discussion as well?
There are a few questions I’d like to post, but first I need to determine how to use this newer style of user-to-user forum. Yeah, it’s been around a few years or so, but I’ve seen it take over the more traditional message board systems like v-bulletin and phpBB. Those boards were easy to navigate, as the forums, categories and topics were presented in a typical directory tree structure (even though the built-in search functions leaved a lot to be desired).
Now the trend has shifted to formats such as this. While some retain some semblance of categories and topics (discussions), others seem to abandon this altogether in favor posts or discussions being related via tags or keywords. Google is the worst offender – forcing the user to select up to 4 pre-defined descriptors when creating a new post.
Also confusing is how the terminology has changed. The forums are now calling topics, discussions. But they end up containing even less actual discussion on the topic and have de-volved into simple questions and answered. This is reinforced by the use of buttons to compel the original poster to designate responses as helpful or correct answers. This I would guess is in response to the myriad of answer seekers posting questions, receiving several helpful replies and never going back to say thanks, thus, the threads become all but useless for others who experience and seek out solutions to similar issues.
The new format also usually starts out with “ask your question here” which is just another way to say, “hey, how about at least giving the search a try before asking a question that’s been covered before”. Because many self-contained search features just don’t work, I can see why users just skip over it. But, what they may not know is that you can use Google to search a specific site. Forum, or blog which usually works pretty well. I’ve done this on a number of occasions, only to find the response as “this question has been answered here a hundred times – try searching”. If the responder is feeling generous that day, he or she may also present a link – a google search link that includes keywords.
So, here I do see the initial ask your question box, then underneath that, a bunch of icons that represent particular products/topics. I start searches using more keywords, the reduce them If there are too many results. This gradual decline works well for Google, but here at Apple Support, I went from over 700 results to just two by eliminating all but the two mandatory keywords. I will do some more searches and post in the appropriate section, but my gut reaction is that it would be hard to believe that I’m the only person who has ever had this question.
So, then – what’s the best and right way to use this new forum?
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
A BRIEF HISTORY OF ONLINE MESSAGE BOARDS
I’m turning the double-nickel this year, so I’ve earned the right to gripe a bit. I don’t know everything, but for those of you youngsters, do yourself a favor a read up. If you truly are a techno-phile, you’ll find it at least somewhat interesting, at least enough to do a little research. Plus, this information isn’t all that old.
The first online community I was exposed to was the BBS – Bulletin Board System. I had just bought my first PC, a Tandy, and the sales guy sold me a modem and gave me a number to call to connect to his BBS. I installed the modem, dialed the number and for the first time heard the annoyingly beautiful sounds of modems connecting. The, almost like “Do you want to play a game?”, text appeared on my monitor and I was hooked. The BBSes were local – to avoid long distance calls – and operated by those who could afford a second, dedicated computer and phone line. Usually, only one person could connect at a time – browse the discussion topics, leave a post to add to the discussion, check private messages (email) then log off.
News Groups were the next form on online interaction I was introduced to. These required a special server running a dedicated protocol and a new reader, usually integrated in with an email client like Outlook Express. Each group was a specific topic – for example, Microsoft groups may have had a couple dozen or so groups covering topics like Windows 95 or networking, other commercially sponsored groups, or self-created groups. Like a BBS, you would log on, catch up on unread messages, respond to some and move on. It was in the News Groups where I learned how to program web pages to connect to a hosted database and many other things, thanks to the expertise and kindness of strangers. These groups soon became the territory of spammers, not to mention the real ugly recesses of the internet – international folks sharing “content” that the work obscene can’t even begin to describe. ISP’s soon dropped news groups from their services and they went away.
By this time however, the world-wide-web was now in full swing. We no longer needed AOL or Prodigy to get on the Net, just an ISP and browser. Broadband was becoming available in select markets. Web-based bulletin boards sprang up all over, filling the void that the news groups left behind. They evolved, but kept to the simple structure and format for a good long while. As the cost of web hosting came down, and the availability of online databases went up, and open source application became better and more robust, anyone could incorporate a forum into their site with little time or expense.
Social Media was on the rise. Sites came and went. From Friendster, to Myspace, then finally facebook, Twitter and LinkedIn. The net also settled in to a short list of other content sharing sites – YouTube, Flickr, Instagram. These took over the social discussion aspects of the online forum sites. That left the forums to take the only remaining role of software and product support – both as an extension of a company’s support solution or user-to-user help and support.
On more than one occasion, I’ve tried to engage other users in topical and conceptual discussion in these groups, but it seems that they’ve already used their energy for that keeping up with their social media obligations. Facebook groups get lost in the multitude of pages. So end user support groups have settled into Q & A, mark the answer as correct them move on. Then another person comes along with the same question, enters it into the box, sees the first ten “pertinent” results that don’t answer the question, posts the question, and the cycle continues.
If anyone has read this far, I commend you! Reading is fast becoming a lost art. I know it’s hard to read off a computer screen, easier on a tablet. And while I live my gizmos and gadgets, I have to still at least once in a while pick up a real book. I’m perfectly satisfied with my iTunes system with the only issue being the quality of any downloaded music. It’s better than it used to be, but CD’s have superior sound. Blu-ray Disc has superior sound and picture.
I did purchase several books from the iTunes Book Store. But why? I could have bought them anywhere and read them in iBooks, but not the other way around. I had to sell my iOS devices. And now I can’t read my books. But that’s another story, for another day.Slip Jigs
Contributors here so far are the cream of the crop...
As an overall reaction to your treatise, I agree. I also judge that you - like me - may have some experience and skill at UX design (User eXperience - usability design, for the unwashed masses).
First, let me commend your use of the WHITE SPACE that Apple graphic designers have so kindly provided. Looks very much like a paper page full of easy-to-read-SERIF-FONT text - it is clear you have experience with design concepts.
As a tribute, I will post in your style - although our compose pane here is not quite WYSIWYG, I am hoping that line spacing will sort itself out, if not I will remove my attempt at bucking the system - but it may time for you to get some new optics
you said:
" ... v-bulletin and phpBB. Those boards were easy to navigate, as the forums, categories and topics were presented in a typical directory tree structure... "
Agree that vBulletin, etc. WERE easy and familiar - but what is this structure but lipstick on that pig - see SITEMAP | ASC (tt2's excellent UserTip). The digital directory tree is merely an adaption of the familiar Fileroom of old... a room for files(computer), file cabinets w/ file 'folders'(folders) and files(files). Apple in the form of Jobs/Wozniak (actually Xerox, but I won't quibble) was groundbreaking in the introduction of the GUI to the masses. [see your comment on being forced to learn a new way of working... has always been thus]
Let me add that the lack of Apple's implementation of the stock features of "Sticky" threads - Announcements, Hot Topics, etc., is a miscalculation. The CATEGORIES above the Using ASC list of threads - "Announcements" and "Community Events" - baffle me as to their usefulness as I can see neither when I click 'em, only some "filtering" of what is in the "Feedback about Discussions" (?Feedback ?about? Disscussions?) Category.
you further said:
"... the trend has shifted to formats such as this. While some retain some semblance of categories and topics (discussions), others seem to abandon this altogether in favor posts or discussions being related via tags or keywords... "
Kids these days... => iDevices (generic for handheld smarty-devices of any stripe) are responsible for the VISUAL graphic design conventions... no more teensy-weensy cursor - but BIG FAT FINGERS.
A good suggestion to submit at Support_Feedback might be to improve the 'Smartness' of the search capabilities by REQUIRING tags to be attached by the OP (offer suggestions if they wish) AND FURTHER, allowing other users of status to ADD tags (see your ¶ #2) - my estimation of the ACTIVE SEARCH is that it is looking for matching terms in the title of a thread, but I have no proof - anecdotal or by documentation at JiveSoftware.
additionally you said:
"... the use of buttons to compel the original poster to designate responses as helpful or correct answers. This I would guess is in response to the myriad of answer seekers posting questions, receiving several helpful replies and never going back to say thanks, thus, the threads become all but useless for others who experience and seek out solutions to similar issues. "
I have no experience with other enterprise solutions, but the scuttlebutt on Jive is that it is the best in the business at Community Collaborative WorkFlow Software for Big Enterprise. We here unfortunately have been given use of a mere pittance of Jive's features. Apparently the MARKUP buttons have a really valuable purpose in the complete package of Jive workflow management. Here, merely a system for rewarding helpers. The green icon goes un-noticed by most and the OPost is likely irrelevant to most individual's issue. Regarding the latter portion, you can't change human nature. Some folks just aren't team players.
you continued:
"... The new format also usually starts out with “ask your question here” which is just another way to say, “hey, how about at least giving the search a try before asking a question that’s been covered before”. Because many self-contained search features just don’t work, I can see why users just skip over it. But, what they may not know is that you can use Google to search a specific site. ... "
This particular issue of "Why do folks not go to the dadgum forum related to their device/software?" has plagued me since actively taking part here. My maladies prompted ME to go directly to the forum/sub-forum where they belonged. Clearly "My iPhone is a BRICK - how do I UN-BRICK IT?" does not belong in this forum - Using ASC - but thousands of similar questions land here - it MAY be because the DEFAULT forum for un-PRE-visited forum at SUBMIT.
The WELCOME page has the preferred path - a "Search or ask a question" field and the teeny -> New to the Community? Start Here. link (actually Tutorials )
-- neither of which content does anything to coach the new user in "How Do I Use This Joint?"
Something akin to "Pick the Device or Software in which you are interested below" might at least get the visitor to the right place to BROWSE their issue. Many folks are unable to craft a TITLE to their question that even resembles their problem, much less explain it in the bodytext.
This is explained in the javascript:; link "How to write a good question" - e content of which I leave open AND hi-lited in a text file ready to copy/paste, for example:
Quoted from Apple's "How to write a good question"
To help other members answer your question, give as many details as you can.
Include your product name and specs such as processor speed, memory, and storage capacity. Please do not include your Serial Number, IMEI, MEID, or other personal information.
Provide the version numbers of your operating system and relevant applications, for example "iOS 6.0.3" or "iPhoto 9.1.2".
Describe the problem, and include any details about what seems to cause it.
List any troubleshooting steps you've already tried, or temporary fixes you've discovered.
Here is how obscure that information is
It's almost as if the confusion is by design.
HOORAY! - another fan of the Google workaround. I get pooh-poohed by some for even suggesting going off the reservation, but it works WONDERFULLY and is FAST AS LIGHTNING with even more useful post-result filtering.
you concluded your evaluation with:
" So, then – what’s the best and right way to use this new forum? "
Learn the system just like you did when you first started using a computer instead of paper. It is what it is. I have a comfortable WorkFlow established using browser bookmarks and Add-ons + Google for all searches + email notifications to sort the wheat from the chaff. Not adopted of my choosing... but at least it's MINE!! Be advised that the SiteWare employs some "we will save you from yourself, helmet-law-like features" that may frustrate you from time to time - until you discover (or are told) how to circumvent them.
Some definitions:
Apple Support Communities = Bulletin Board Software Site
Community = Forum
Category = Sub-Forum
Question = Thread
Reply = Reply
Your not so "Brief History..." is clearly a good evaluation and Executive Summary. Are you SURE you're not an interactive developer?

Having a few issues with several programs (tor / mpd / ccm..)
Hey everybody,
I'll arrange this post in 3 parts since I have 3 different kinds of "major" problems or questions .
1st ( tor - privoxy - polipo - iptables )
I somehow found this article in your wiki and therefore tried to get tor and privoxy up and running on my desktop machine, as this didn't work as I hoped it would I searched farther in the wiki and installed and configured (as far as I've thought of) polipo and iptables.
Now I've put all 4 of them in my rc.conf, but somehow some of my http connections don't seem to work in chromium while iptables is running (https works fine though [e.g. archwiki works, youtube doesn't]).
I did everything as suggested in the polipo wiki entry, meaning I changed my /etc/iptables/iptables.rules to
*nat
:PREROUTING ACCEPT [0:0]
:POSTROUTING ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A OUTPUT -p tcp --dport 80 -m owner --uid-owner polipo -j ACCEPT
-A OUTPUT -p tcp --dport 80 -j REDIRECT --to-ports 8123
COMMIT
and removed all proxy settings from my browser - meaning all corresponding flags in the startcommand. I also added "forward / localhost:8123" to the privoxy config and changed the polipo configuration according to the wiki in order to work with tor (the socksParentProxy, socksProxyType part).
now the next problem - that might probably be related to the first - is that my privoxy doesn't load in daemon mode anymore.
I think it's since I've installed polipo that privoxy began to refuse starting together with the other daemons
[usR@machine ~]$ privoxy
Apr 23 00:20:56.459 b75086c0 Fatal error: can't check configuration file '/home/usR/config': No such file or directory
this is the output I get when I try to start privoxy in normal user mode from the terminal, when I try starting the daemon manually (/etc/rc.d/privoxy start) it says
touch: cannot touch `/var/log/privoxy/logfile': Permission denied
chgrp: cannot access `/var/log/privoxy/logfile': Permission denied
chmod: cannot access `/var/log/privoxy/logfile': Permission denied
touch: cannot touch `/var/log/privoxy/jarfile': Permission denied
chgrp: cannot access `/var/log/privoxy/jarfile': Permission denied
chmod: cannot access `/var/log/privoxy/jarfile': Permission denied
Apr 23 00:22:34.490 b76396c0 Fatal error: Cannot setgid(): Insufficient permissions.
[/var/log/privoxy belongs to privoxy:adm]
when I do the same in sudo mode it just fails without displaying an error message..
I added this code to the /etc/rc.d/privoxy executable but I still get this owner conflict error and I have no idea what might be causing it.
if [ ! -d /var/log/privoxy ]
then
mkdir /var/log/privoxy
touch /var/log/privoxy/errorfile
touch /var/log/privoxy/logfile
chown -R privoxy:adm /var/log/privoxy
fi
If the order of the daemons in rc.conf is of any real importance here a copy of my setup
( @polipo @privoxy @syslog-ng !set-hw-addr !iptables @network netfs hddtemp @crond hal dbus @alsa @slim @tor )
2nd ( mpd & mpc )
I'm just wondering if there's a way to output the position of a track in the current playlist combined with a search. since mpc search <type> <query> only prints out full file path and name, but not the position in the playlist so that you could play it with mpc play. I thought of a method to print out the whole list with mpc playlist and pipe this output into a listing program, than grep out the song I'm looking for all that in a little bash script, to replace mpc search.
Is there an integrated mpc search function that works the way I imageine it and my idea therefore redundant, or if not, is it realizable the way I picture it; does such a listing program exist?
3rd ( cairo-compmgr )
Since I'm already posting here I thought I'd mention my older problem which I still couldn't solve.
1st) I need to start cairo-compmgr(-git) in sudo mode to be able to edit any settings or activate the gui in any way. how do I automatically start the program on startup in sudo mode? I tried editing ~/.fluxbox/startup & ~/.fluxbox/init, even tried adding it in /etc/rc.d/ and /etc/rc.conf in order to start it as a daemon (lol, noob) but none of that worked properly obviously Any ideas? I don't want to start it manually and "waste" a terminal window for that every time I boot.
2nd) I can change opacity (transparency) in both versions only per hotkey, and when I do so the settings don't get saved, they even get reset to normal opacity as soon as another window gets selected. does anybody know if there's a config file or any way to save opacity settings for certain windows & programs, so that they automatically get loaded when cairo starts and stay applied until it gets closed?
[or generally: how do I configure the Plugins? ]
the last "problem" which occurs only with cairo-compmgr-git:
When I rightclick the ccm icon in the task bar and disable the composite desktop, the whole program kills itself oO
In the old version the option "Composite desktop"'s box just got un-checked and I could easily restart ccm by rightclicking the logo again and re-enabling the "Composite desktop" option.
Any clues on that by any chance?
I'm using Fluxbox by the way, if that's of any importance for any of the problems. hope I didn't forget any important information if so please remind me
Would be thankful for any kind of help
have a nice weekend

//edit:
concernig the tor / privoxy problem, I managed getting all the daemons to start up at bootup again, my iptables situation remains the same though.
I went through all the config files again and played around with chown and chmod a little and for now the system is stable, everytime I reboot all the daemons start without any problems.
but when i start chromium with --proxy-server=localhost:8118 now, I get the following error message
The following error occurred while trying to access http://torcheck.xenobite.eu/index.php?:
504 Connect to torcheck.xenobite.eu:80 failed: SOCKS error: network unreachable
Generated Sat, 23 Apr 2011 04:49:08 CEST by Polipo on archzor.localdomain:8118.
notably with all programs running now, tor, polipo, privoxy (and by now dansguardian as well)..
I'm tired so I'll go asleep now, maybe I'll find something tomorrow in the logfiles or whatever, so far:
every kind of help is still very appreciated

Last edited by deF291 (2011-04-23 03:13:48)okay I've finally been able to get tor and all the other programs to work according to my plan the only thing that's still making problems is that iptables doesn't work as I want it to, when I start chromium without proxy settings privoxy doesn't seem to forward the information to polipo.. do I need to add another rule to iptables.rules in order for the program to know it has to reroute the information again or how can I get this to work? and is there any way to run rtorrent with proxy support?
anyway, problem 2 and 3 are still to be solved.
and does anybody know where i can get a good dansguardian blacklist that was not designed for 6 year old children and for which I don't need to subscribe? I'm still getting these partypoker popups -.-
//e: with iptables it's the same thing as described in the first post. https works, http doesnt. I get the output "Invalid header received from client." on http sites. still no idea why though.. (and the https-version of torcheck.xenubite says i'm tor unprotected while starting the browser with iptables)
