I wonder if there's a way to capture the same information I can get from nethogs to a file. All I need it per process (rather than per interface) what is the sent/received traffic.
View 1 RepliesI've been searching for this and hope there is a fairly simple fix. I have a pc that resides in a small bldg. at the base of a radio tower in Central America. It receives a stream from the main studio, it then broadcasts through our tower via the stream, on occasion it will lose the stream (foul weather, etc.) Often times it will fail to reconnect, I have used various players, VLC, rhythmbox, mplayer.
Is it possible to have a cron script that will check the stream, if all is true, then carry on and if false, reconnect to the stream? If so any pointers or directions?
How do you list processes, get a process's std(in|out|err) stream, or wait until a process is finished in C?

I have a game server running using java, and it tends to crash sometimes, and only way to start it now is manually, so i thought i could create a script to check periodically if java is running, and if it isn't, run my startup script for the game server also, if it's possible it should log when it actually started the server startup script into a text file or something, so i can check why it crashed.

We've just set up 3 Dell systems with 64 bit Red Hat Enterprise Workstation 5. As part of our system configuration we point the user authentication to our LDAP server, and automount people's home directories from our fileserver. At this point, our security people do some configuration and we get it back.
We are typically running KDE. On all three machines, when you plug a USB stick into the system, the familiar window pops up asking you what you want to do - open the contents in some program, open a file viewer, etc. and the stick shows up in /media When you stick a CD or DVD into the drive nothing happens - you don't get the options window and nothing appears in /media I'm trying to get an idea of how the automount process works, and where I may have stepped on it. We've got three more identical machines that haven't been installed yet, so my plan is to check the ability to automount CDs at various stages of our setup process.
I have an ubuntu 10.10 server and want to run a script on it to check if a process is running. If it is not running, it will start the process and also write into a log file.
When running the script i get the following error message:

Here is my script.
I have an Ubuntu server in which a file is dumped every hour and a new file for the next hour and the process continues. If there is any problem due to which the creation of file stops then empty files are created every minute till the process is killed & started again. I need help to make a shell script to check if the empty files are being created and then kill the process and start it again.It would be a great help if anyone can help me regarding this.

I have a USB modem and a large C++ application that needs to detect whether that device is present or not. I was hoping to get advice for what the best method to do so would be. The only solution I've thought of is to parse the output of lsusb and look for the vendor and product ID of my device, but that seems a little hack-ish and inefficient. Is there a command or program that I can provide it a vendor/product ID for a USB device and it can tell me whether or not such a device is present in the system? Or another, better way to detect the device than parsing the lsusb output that I've been thinking

A similar problem to this one :

I do not have Gtk::Settings and I have looked in ~/.gconf/desktop/gnome/ but I do not have an interface folder and none of the others I opened have any font details.
I have tried simply not setting a font within my application but it is using a font not specified in the Appearance Preferences at all. It looks like Times.
Ideally I would like to be able to get this information from Ubuntu using a native process :

I have a default installation of Ubuntu 10.4 with Unity running on top of Gnome. (I think this is correct. I certainly can get Nautilus running quite easily and as I mentioned earlier I have ~/.gconf/desktop/gnome/ folders).
The brief is to get the application working on the default installation so I cannot install anything but the target machine I am using has got 'gconftool'.
I need to generate pdf documents programmatically using Ruby. i.e. I don't want a GUI interface but an API interface. The bulk of my document is text but there are images included as well. I've looked at this thread: [URL] and it's 2 main recommendations PDFEdit and ImageMagik. PDFEdit has scripting available but I can't get my head round how to call this using Ruby. ImageMagik has a number of Ruby wrappers and is the kind of thing I want but as far as I can tell it only deals with Images and my stuff is mainly text.
View 1 Replies View RelatedIs it possible to do the following in C/C++ in Linux:Without direct linking (my program should NOT depend on Qt or GTK), display a GTK or Qt based file dialog.The behaviour should be something like this when my program runs, when you want to open a file:The program scans whether you have Qt installed. If so, it somehow manages to link itself to Qt (e.g. dynamically loading the .so file) and display its file dialog and get the path from it. If Qt wasn't found, it tries the same with GTK. If that also wasn't found, it displays a less powerful replacement dialog instead (better than nothing).
Or is there any other simple way in Linux to get a standard file dialog somehow (similar to when compiling for Windows you can very easily get its standard file dialog, no matter what version of Windows, in your code, even if your program doesn't use any other Windows GUI at all).
I am writing an application that has a web service client on a Windows PC that needs to call a web service on a Linux server. In order to create the client, I need to be able to programmatically read the WSDL on the server and use it to create the client. I'm using the web tools in MyEclipse to build the client.
The Linux server is running Red Hat, I believe, with ssh enabled. I can connect from Linux to Windows with no problem, but I can't reach the Linux box from Windows. I get one of three errors when I try: no path to host, connection reset, or unknown error number, depending on the port I use. I've googled for an answer, but haven't found anything yet.Is there some way to add the Windows IP to a permission file on the Linux machine so it will be recognized when it queries for the WSDL?
Given a matrix with 0,1 entries, how can I create a graphic in linux such that we have a black square or pixel if the entry is one and white otherwise?
For example, if the matrix is:

0111110
0000000
then I want a graphic that looks like:

I will be working with many large matrices, e.g. 1000x1000, or 5000x1000 so I need to do this automatically.
I know the tool system-config-display can tell me all about my display but it's not available on all systems and so I'm looking for alternative ways to get my monitor type.

Is there some place to get this info, say in a config file somewhere?

View 2 Replies View RelatedI have a MacMini connected to the big-screen tv on one side of my living room. I have my gaming computer on the other side of my living room. I often use VNC to control the Mac, so I don't have to get up to change which iTunes playlist I'm listening to, or play a movie, or whatever.I would like to be able to do something similar with the audio.Here's my problem. Sometimes it's really hard to get the volume just right when I'm at the far end of the room. If I increase the volume to a level where I can hear everything, it sometimes annoys the neighbours.
So, is there a way I can stream all the audio from the MacMini so I can listen to it using a Linux laptop at the far end of the living room without annoying the neighbours?Because I want to set this up for watching movies, it needs to be fast enough to stay in sync with the picture.(It might just be easier to run some speaker wire across the room, but I like to try to do things the hard way first. Heh heh heh...)

when i start windows mediaplayer ( a requirement), i can browse over my pc when i am on the interface of the em7075 ( what you see on tv when go to the hdmi channell.) in other words, i have the option to play / stream a movie from my pc, over the network to the em7075.
