Ubuntu Servers :: Edit Sshd_cofig To Enable Audio - Or More - On Remote Login
Aug 23, 2011
I need sshd (thats the ssh host) to enable, or be allowed to enable audo when I log in. Once I log in to my server locally, sound is enabled as long as a local bash is active. When local bash is active, I can run command line audio operations, in various audio programs via an SSH terminal, and have the sound work at the server.
I want the sound (device(s)?) to be active, enabled, loaded, (NOOB here) when I am ONLY logged in via SSH. I don't want to have to go to the server and log in to a local terminal to have audio loaded, this defeats the point of using SSH.. LOL sound needs to work on that server with no local login, I.e. the screen says "computername login:"
So there is something I'm missing here. Ive read over the sshd documentation many times.. Some of it is beyond my skill set, so I'm sure i'm missing something.
Or perhaps sshd needs permission to load the audio? I don't know here I'm a noob.
(I suppose I should add, this is gnome system with X disabled with the runlevel edit to gdm.conf. but audio works without starting X, so I doubt the problem lies here, as I said before the SSH connection does what I need it to as long as a local BASH (not X) session is logged in.)

I did a upgrade to 10.04 on my server. Then after a reboot I was unable to remotely get into server. Upon connecting the monitor I am greeted with the purple 10.04 boot screen with this text at the bottom:
Code:
The disk drive for /dev/mapper/cryptswap1 is not ready yet or not present
Continue to wait; or Press S to skip mounting or M for manual recovery
Now I did some googling and the results I came across involved a encrypted drive which I have never even tried to setup. Now if I choose a manual recovery I am dropped to cli which from there I can start networking then ssh into the system and run updates, ping other machines, etc. But again this is meant to be a remote access server so everytime I reboot I cant just hit the M key let alone run service networking start! So I commented out the swap entry's in both my /etc/crypttab and /etc/fstab...now I cannot even get to terminal as I could before...now it just loops with no errors!

In my desire to learn, mess around and set up something useful on my home network, I'm looking for something that can do centralized login and remote home directories. When someone in my family logs in to a computer, windows or linux based, I want them to be able to use their credentials, then have their remote drive mounted and ready for use. I've looked over ldap solutions, attempted to set up an OpenLDAP server and realized I have no idea what was going on. Is an ldap implementation the proper way to go for my desired solution or am I barking up the wrong tree? I've just now set up OpenDS on a VM for testing but I need to do some research there.

I recently configured a server that I would like to access remotely. I want to start x through ssh and then log in through vnc, but I get prompted to type in my password in gnome before I have a change to login. Which is a problem because you need to be at the box to enter the password. Is there a way to authenticate this through ssh or give vnc automatic keychain access?

I maintain plain vanilla Ubuntu 10.04 systems for several friends. Each machine has only one user, the owner. I use Remote Desktop to instruct and to perform maintenance. Here's my problem:After updating the system, if the kernel has changed, a restart is needed. If I do a restart, I then have to phone the owner to insert his login credentials in the gdm login screen, before I can do anything else via Remote Desktop on that machine.There ought to be a simple way I can avoid the phone call and login myself.
I'd strongly prefer not to use any software that is not included in a plain vanilla Ubuntu 10.04 installation. And I don't want to weaken system security beyond what it is now.Is there a solution? Or, what is the simplest solution?

Is there a video editor that also allows me to edit the audio. For example I have 2 videos and want to take the audio from one clip and add it to the other clip. I have tried Avidemux and Pitivi but these don't seem to have this ability.

I have a few music videos in mkv format that are edited. I'm trying to replace the words that have been edited out, but having trouble aligning the audio and saving a finished product. In Windoze I would use Goldwave and/or Multiquence for any simple editing needs. I tried using Multiquence via wine, but it needs DirectX and winetricks isn't enough to alleviate the problem.
I figured there must be some similar apps available for ubuntu and there definitely are, however they're not for simple editing like I'm attempting and more for the advanced user looking to do multi-track creating and editing. I've tried to find online tutorials and help via searching but am just getting a headache.

I just had a quick question. I would like to burn a DVD to disc. The VOBs in the Video_TS folder have 3 Audio tracks: Stereo, Surround, Mono. By default it plays the Stereo track. Is there any way to change this? ffmpeg -i [insert_video_location] in the terminal gives me:
Code:
Stream #0.0[0x1e0]: Video: mpeg2video, yuv420p, 720x480 [PAR 32:27 DAR 16:9], 9800 kb/s, 29.97 tbr, 90k tbn, 59.94 tbc
Stream #0.1[0x80]: Audio: ac3, 48000 Hz, stereo, s16, 384 kb/s
Stream #0.2[0x81]: Audio: ac3, 48000 Hz, 5.1, s16, 448 kb/s
Stream #0.3[0x82]: Audio: ac3, 48000 Hz, mono, s16, 96 kb/s
Will 0x80 always be the default? Normally this wouldn't be a problem, but I'm going to be playing these discs on a DVD Player without a remote (can't help it), so I won't be able to switch the audio on the fly, and they have no menus. You put it in, and it goes straight to the movie.

What's the fastest and most reliable way of working on files on a remote linux machine with emacs on a windows host machine? I need to be able to easily copy and paste text between emacs frames and use all the keyboard shortcuts, so putty and cygwin are out of the question. I've tried tramp mode but it just hangs when I try to connect.

I have a webGUI in php where users can make certain settings. How can I edit a file on a remote server from my php webserver? Currently I use my FTP client, vsFTPd and a chrooted user in a specific directory where the file resides. I think this is pretty save as long a nobody else uses my FTPclient. How can I make changes to this file on the remote server from within my php-code on my webserver ?? (so that not I need to make the changes but my users can do it from a html-form) I found this but the credentials for the FTP-connection are plain :
<?php
$file = fopen ("ftp://loginasswd@server", "w");
if (!$file) {
echo "<p>Unable to open remote file for writing.
";
[code].....
I use https for the webGUI, but I guess this does not mean the connection to the remote server will be encrypted also ? Can I use my FTP-user (has no shell) from within php to edit the file ?

I am trying to use FC12 to edit multimedia projects for my work.
Right now I just want to edit some audio in Audacity.
I switched back to Linux after a few years, because it usually is "better" than Windows.
I cannot get any sound. I installed ALSA removed and reinstalled PulseAudio and everything else I could find in a forum, to no avail.
Linux tells me my sound card is: 00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 02)
I used to be able to play MP3s but that went away in the process of all this.
Is there one solution I am missing, or do I have to change everything around depending on what I am doing?
I would like to use Linux for this but deadlines might make me go back to the dark side....

I am unable to play audio CDs. I have 2 CD drives and upon insertion of of a CD into the top drive, it notices the CD and asks what I want to do... Play with Kaffeine results in it opening, but then nothing happens. When I do the same thing with the CD in the bottom drive, it plays the first track of the CD but nothing else. Every time. With different CDs.

my local box is centos 5.5 running gnome.
I have a eucalyptus instance (vm) running an older version of centos (5.3?). As a vm it has no graphical display. I'd like to run a graphical app there so that it displays back on my local machine.
Used xhost locally and it shows the remote IP (eucalyptus instance) as enabled. On the remote side (eucalyptus instance) I set DISPLAY with:
export DISPLAY xx.xx.xx.xx:0.0
where xx.xx.xx.xx is my local ip address. Oh, I did install X in the vm instance (yum groupinstall "X Window System"). X is installed but not running there (does the point of origin of the x app need to have X running as well - and what does this mean in a vm which is a non-graphicla environment?).
Anyway, I try to run (from remote to local) xclock and get the typical
Error: Can't open display.

I have Songbird running on another display on the same machine as my Mythtv frontend but while the frontend is running, audio seems to be disabled for it and other applications. I assume that this is because Mythtv suspends Pulse audio.
Is it possible to make this work without enabling pulse audio?

I am trying to get the 5.1 audio working on the gigabyte g31m-es2l mobo which has ALC883 audio chipset.Its onboard audio.
Its a fresh installation of ubuntu.I have set the sound properties as below.The speaker test only works for the front right and front left speakers.Rest other speakers are muted.
Also tried editing the /etc/pulse/daemon.conf file with uncommenting the audio channels from 2 to 6 and rebooting.Still its not working.
Tried running the following command and again only the front right and left speakers light up.

At the moment I'm running Putty on a windows box at work to SSH in and tunnel port 5900, then I execute
Code:
x11vnc -xkb -ncache 10 -safer -localhost -nopw -once -display :0
from the shell.
I run ssvnc and tell it to connect to localhost, and we're good for remote desktop.
The next step is to push my luck and see if I can get streaming audio as well.
ssvnc is supposed to automate many of the required processes, making the use of a standalone ssh client like Putty redundant - it bundles a similar program, passing commands through ssh from its GUI
Under options/advanced it has a facility to 'Enable ESD/ARTSD' audio tunnelling and it bundles a windows-executable (using cygwin library) version of ESD, so it just needs some configuration.
When you click that option there's a documentation pane that says you can put
Quote:
esddsp -s localhost:16001 gnome-session
in your ~/.xsession startup file but since I use my Lucid box for local sound as well I'm not sure that's ideal as I want to use JACK, etc. and it looks like this command would route all audio to network, all the time.
ssvnc suggests using "x11vnc -create" mode to start it up in a virtual X session through Xvfb but it doesn't really go into any more detail as to how you do this.
I've installed Xvfb through synaptic, and that's as far as I've gotten.

Just did a fresh install of Karmic, got all necessary decoders installed for video and audio playback...I think.
Problem is I can't forward/search in audio files I am playing. I mean I can only Play, Pause, Stop or "Next-track" a music file. Video files are fine.
I've tried Exaile, Rythmbox and even Totem. It is like the audio files are "half read-only".
If I drag a horizontal scroller in the music player and let it go, it will only jump back to the position where it is actually playing.
Has anyone experienced, this? I am a missing something in gstreamer or something like it?

For X-Mas I got myself a nice little nettop running off an ION motherboard. how to enable HDMI audio output, but got it to work. I've realized that when I'm in XBMC (which is admittedly the only place I watch movies) certain sounds like gunshots will be extremely louder than something like dialog. My friend believes that I should mess around with the channels (to fake the center channel from the left and right) I don't want to threaten Linux, how lightweight I can make it which is critical to an HTPC, but considering XBMC just got a Netflix addon
