Ubuntu Multimedia :: Unlisted Remote - Capturing IR Code
Mar 1, 2011
I have a unlisted remote which I can't find a lircd.conf for. Have tried irrecord with a mceusb receiver and have had no success. I am running maverick on a fresh install. LIRC is install and functions correctly for MCE remote and sending dishnetwork ir codes. I have found the hex codes for it but have no idea what to do with them even if there is anything to do with them. My question is this, is there any other way to capture the remote codes other than irrecord? Is there a way to manually build the codes?

I want local programmatic access to ssh output in Mac Terminal. First, I tried redirecting the output of each command to a file. The file was perfect, but of course it was on the remote server, and an sftp for each command output seemed a little.. Next, I tried to Applescript Terminal, but it only gives access to the currently visible text in a tab (i.e. if half the output has already scrolled out of sight, it doesn't get returned - useless).
Last, I tried piping ssh to tee (e.g. ssh user@host | tee output.txt). This almost worked. I have the output in a local file, but there are a lot of unwanted characters mixed in. For example, every time I hit backspace, there's a ^H in the file. There's also text like "[0m[K" which is harder to get rid of.

According to 'man luvcview', if I do this:
Code:
luvcview -o testvid.avi
then luvcview should capture the video to the .avi file. However, when I try it, no output file is created. Grabbing a raw stream or raw frames works fine, but not the creation of AVI files. Am I missing something?

I've tried to look up different programs for this but can't find anything. I'd like to be able to open my recorder on Myspace for instance and capture any sound playing through my speakers. I used to have a little program for this, but its windows based and won't seem to install correctly in Wine.

I want to capture DV-video through IEE1394 (FireWire) with Kino and Ubuntu 10.10. Seems I can't capture... When I plug in the camera there is no hot plug message (if there should be one? I've read it should...). The DV-out on the camera is enabled There is no option to enable/disable the port in my BIOS.
Some information:
Code:
a~# lspci | grep 1394
07:09.0 FireWire (IEEE 1394): Ricoh Co Ltd R5C832 IEEE 1394 Controller (rev 05)
Hope there are some command to check?

I've been trying for a while now to capture videos with my webcam of my samsung n110 netbook, I am running ubuntu 10.4 and cheese 2.30.1. I can take pictures fine, with effects and everything but when I press "start recording" the webcam seems to turn off or all I see is a black image, then when I press stop recording the camera picture comes back on and then the program freezes. I've tried turning down the resolution, I've tried all the possibilities in gstreamer-properties but nothing helped so far running from terminal didn't give me a clue on what the problem might be either. I would like cheese to work to have photo and video in one program but if someone has a good program to capture video I am willing to try it out.

I am having problems with ffmpeg. My goal is to capture a video stream from my webcam and feed that into a webcam-capturing program. But to get that to work, I will need ffmpeg to work. I need the following command to work, but I get an error:
Code:
$ ffmpeg -b 100K -an -f video4linux2 -s 320x240 -r 10 -i $device -b 100K -f image2pipe -vcodec mjpeg - | perl -pi -e 's/\xFF\xD8/KIRSLESEP\xFF\xD8/ig'
ffmpeg: relocation error: /usr/lib/libavfilter.so.2: symbol avformat_find_stream_info, version LIBAVFORMAT_53 not defined in file libavformat.so.53 with link time reference

running a java application in a remote site,and I would like to debug the application. I'm using jdb, and, due to network architecture, I can only use jdb do debug in text-mode. To debug in text-mode I use the command: jdb -attach remotesite: port. At this point this is ok. Now I would like to attach the source code to the jdb. I tried the command
jdb -attach remotesite: port ~/src/org/path/file.java
to attach the source code to the remote debug to. But it doesn't work. In jdb, I try the command use ~/src/org/path/file.java but it doesn't work either. How can I attach the source code to the remote debug?

Canon cameras used to come with a piece of software called remote capture for Windows and MacOS.
You plug in the camera via USB, and then the camera display is on your monitor. From there you can do everything your camera does, like taking pictures of video. Does anyone know if there is linux equivalent software that can do this?
I have found this software, but new cameras aren't supported.

I love Ubuntu but there is just one thing that I cannot get working. I have vista on this computer (Which I am going to delete after I get this working) when this computer is booted into vista then I type "192.168.1.65" (which is this computers internal ip address) and it connects to it without a problem. When I try this on ubuntu with KRFB running I type "192.168.1.65:5900" as it tells me to do with the added port number. This computer (This is the one I am Connecting to says "The remote user has been authenticated and is now connected." and when I hover over the icon it says "Desktop sharing - Connected with 192.168.1.70" which is my laptops IP address. On my laptop however it says "Remote Desktop Disconnected Because of a protocol error detected at the client (code 0x1104), this session will be disconnected. Please try connecting to the remote computer again." No matter how many times I try it doesn't work.

I am implementing an automated backup scheme so I created a shell script which first creates SQL dumps for all MySQL databases, then retrieves all websites from the /var/www directory of a remote server. The latter is working as I am using rsync to get the remote files.However, the MySQL dumps being retrieved are the ones from the local server which is not what I want. I want to get the SQL dumps from the remote server as well.I have a tunnel between the local and remote server which I can connect to without using any password (I added the public key to the authorized_hosts), so I tried to add the following code to the script:
ssh user@192.168.x.xxx
I then attempted to retrieve the SQL dumps and exited from the remote server. However this does not work as I still have to enter exit manually in the terminal for the SQL dumps to be retrieved from the remote host. I don't know why this is happening. This is what the script is trying to do:
//connect to remote server
ssh user@192.168.x.xxx
//retrieve SQL dumps
[code]...
Is there a way to connect to the remote host AND run the script's code on THAT remote host?

I would like to capture all output spewed to a terminal session including processes that are terminated that were invoked from a script running in a terminal window. this is beyond capturing just stderr and stdout . for example
{
./script
} 2> stderr.cap 1>stdout.cap
if script is terminated (including because of memory violations) I get spewed output to the terminal I would like to capture that spewing to a file automatically or to a bit bucket /dev/null Is there another filehandle which can be redirected to do this? If so how or is there another way???

I have four primary partitions currently. I need to keep all of them. I need to make a fifth that is also a primary partition. Is there a way to somehow make a partition into a partition that's in an extended partition without losing any data? Maybe you know of another solution to my problem, but this is the only one I can conjure up. The second problem is much less severe. I can't find any screen capturing software for Ubuntu that will record my desktop and simultaneously record sound from a microphone.

So I've noticed that some applications block keystrokes and input from reaching Ubuntu. Most recently I got the Linux version of Unreal Tournament 2004 running. Problem is that when I'm playing Unreal it captures all input, so when I decide the game is too loud or too quiet, rolling my volume wheel doesn't adjust the volume. I either have to pause the game so it releases my mouse(only in windowed mode), or exit altogether, adjust the volume, and restart the game. Is there a way to change this?

Was trying to use wireshark to pen test my network and I can't get it to work properly.When capturing on my main wireless card wlan0 atheros ath9k the program freezes after a short while and I can't even access the web anymore. Not to mention it stops capturing. I have to disconnect and reconnect to get back on the web. Not sure what is going on here. I get the following output in terminal:
(wireshark:2240): GLib-GObject-WARNING **: /build/buildd/glib2.0-2.26.0/gobject/gsignal.c:3081: signal name `depressed' is invalid for instance `0x2142cb68'

I run a 3rd party command line utility and it works fine, but sometimes it says "Error blah blah blah... Connection timed out"
I want to script this utility, but I need to not execute the commands in the script if it gives me that connection timeout error.
bash code to capture that response from the utility? Something along the lines of:
Quote:
#!/bin/bash
3rdpartyutil > /tmp/temp.txt
if [ ! -f /tmp/temp.txt]; then
echo no error, run whatever you need to man
fi
rm /tmp/temp.txt
Unfortunately, that doesn't work because the utility outputs non-error information to the screen even when it is successful, so it always outputs something, I never need to see it, but I do need to be able to act upon if some of that text says "error" or "connection timed out"

I've made a simple php wrapper around scp. It works fine, but unlike when I run the scp command straight from the console, there is no output returned. I've tried using passthru(), exec(), system() and shell_exec(), all to no avail. I'm redirecting stderr to stdout already.
For example:
PHP Code:
<?php
$command = "scp -C -r $files $target 2>&1";
exec($command, $result);
print_r($result);
?>
Will scp the files correctly to the server, but doesn't print any output - $result is just an empty array. I'd like to see the output so I can visually confirm that the files have been transferred correctly.

I can't seem to figure out the secret to send ctrl-alt-del to a remote Windows box using KRDC 4.4.4. Tried in windowed and full screen mode - no difference. Tried enabling "Grab All Possible Keys" in KRDC tool bar - nope. In all cases, ctrl-alt-del and alt-tab are sent to localhost. There are some mentions of a "config special keys dialog" for KDRC in a few places, though I don't actually find this anywhere in KRDC itself. Documentation for KRDC at the KDE site is very minimalistic. This should be super simple, but I can't quit seem to get it.

I want to capture PID of a program and kill it using the PID if the program is been executing beyond 5 seconds.The problem I'm facing is I have another copy of the same program running under different shell script, and the above code is killing both the process. How do I specifically kill the program which has started under the current running shell script.

I have a GPS device which sends in data on port number 5000, i am able to capture the data into a pcap file using tcpdump. Now my problem is, i need to pipe the data into a text file as and when data arrives into the pcap file continuously.I did extensive search, but to no avail. been trying to solve this for the past 3 days. I use the following commands to capture and pipe the data, but that happens only once when i issue the command. I want this to happen continuously as and when the data arrives.

I listen to a radio show that broadcasts online a lot named ChatterBox Video Game Radio, and when i e-mailed one of the hosts about retrieving archived shows since the site didn't have any archiving of old shows or a link to it. Alon was nice enough to send me one of their old web pages with a HUGE list of archives but it's only the xml source code of the page. since the page isn't live of course, and because of the how he had to send me the code for the page and not a hyperlink to the page, i have the source code. now going through the source code of the page he emailed to me, i can find links to .mp3 files and i can open them and listen to the shows in web browsers, but i was hoping to save them to my computer forfuturelistening.URL]ww.chatterbox'ssite.com/whatever/anotherfolder/showiwanttosave.mp3 in firefox quicktime comes in and lets me listen (as long as my internet connection is active) but wont enable me to save because i dont have the pro version of quicktime. quicktime is good, but i dont use it enough to actually buy the product, and i'm not going to buy the product for just a one time use. is there another way to where i can save this file using the address from the source code (and the ChatterBox allows listeners to save their shows to computer for free, so it not some work around to rob them of money. i fully support them) without having to buy quicktime 7 pro(a product i never really use)?

I never upgrade from one release to the other but rather do a completely new install. How can I keep my Gnome settings from the current release and somehow impose them after a new install. I am not sure which files/hidden files I should carry, save, possibly to a USB stick or whatever and a reasonable procedure to copy/impose them after the new install is stable.
