I've written a shell script to soft-restart HAProxy (reverse proxy). Executing the script from the shell works. But I want a daemon to execute the script. That doens't work. system() returns 256.

I want to create a single client that issues unicast requests for data from any of many workstations on the same LAN. The client will likely run Linux, but the workstations may run any OS.

hi there! i'm currently working on an app for the android os that displays some data. to ensure this data is up-to-date, it is required that the app fetches updates from a remote server from time to time. as the data does not change very often, this update should be carried out once per week. i want to give the user the ability to choos...
I've found out that native files access has no "non-blocking" state. (I'm correct?) I've been googling for daemons which are "non-blocking", and I've found one which achieved said behavior by threading file access operations, so that the daemon won't block. My question is, wouldn't threading and IPC'ing such operations be rather expens...

Hello there! I have build a little daemon in Java and I would like to run it as a service under Unix (e.g. Debian 5). I have read, that there is a possibility of using a Java wrapper - but isn't there any other option which is easier to implement? Can't I just use a Unix command such as "xxx java -jar program.jar"? Thanks in advice, gu...

I've seen embedded boards before that have an LED that flashes like a heartbeat to show that the board is still executing code. I'd like to do something similar on an embedded Linux board I'm working on. Given that it's a fairly trivial bit of code, it seems likely to me that someone has already written a daemon for Linux that does this,...
Is there a preffered place to store a pid file for a daemon that's run as a user? /var/run is the standard place, but this is for a user daemon so it doesnt have write privelages there. Presumably my daemon will be started from .profile or .bashrc or something. Is just saving it to /tmp a bad idea? ...

Hello, I set up an emacs --daemon in order to startup emacs faster. I like especially the GUI version of emacs, so I do emacsclient -c to open a new emacs frame. The problem is that I have changed my fonts, but these fonts aren't loaded if I start emacsclient -c. However, they are applied if I start just emacs (but this causes the who...

I want my node.js server to run in the background, ie: when I close my terminal I want my server to keep running. I've googled this and came up with this tut, however it doesn't work as intended. So instead of using that daemon script, I thought I just used the output redirection (the 2>&1 >> file part), but this too does not exit (I get...
