Some background: on Linux HA, resources and groups have scores, i.e. score=(preference + stickness - failure stickness*fail counter). When a backup node has score greater than that of the current node, the resource will move to the backup node. I need to check, for a given resource/node, if that score is negative. It is easy to get fai...

Hello, at my company we have a really annoying problem with our linker (ld 2.17). It links very very slow on a relatively fast system (Core Duo, 2GB Ram) and i don't really now how to fix this. It takes about five to ten minutes to compile a relatively big project (which takes about 5 seconds to link on my Gentoo system). Personally i ...

I created a script that accepts some form variables and then downloads a file to the user. Here si the code: header('Content-Description: File Transfer'); header('Content-Type: ...
Hello there, I would like to prevent one of my root process from deleting a certaing file. So I came across the flock command, it seems to fit my need, but I didnt get its sintax. If I only indicate a shared lock, it doesnt work: flock -s "./file.xml" If I add a timeout parameter, it still doesnt work flock -s -w5 "./file.xml" It ...
Hello, I'm trying to build a hello world using GTK, which includes the line: #include <gtk/gtk.h> as you would expect. The Makefile supplied has the line: GTK_INCLUDE = -I/usr/local/include so it would expect to find gtk.h in /usr/local/include/gtk/gtk.h. However on my system, it is located in /usr/local/include/gtk-2.0/gtk/gtk.h...
I've setup simpletest to work with my cakephp. I did it as prescribed in the book.cakephp.org. Everything seems to work fine - i've made my first test - super. But the visual layout of the testpage does not look right - I'm talking about www.mydomain.com/test.php. It looks like it has no CSS. I've seen this with the cakephp framework,...
Hi, Could anyone provide me with the pointers to source code for linux commands such as 'sort' , 'uniq' etc. many thanks. ...
Here is the limitations: No public key file uploaded to server (since this may be run at different target machine), this is just for an automatic testing program, so security is not a concern. It's automatically program run background, so no user input. I do not want to use "expect" which require user to install. I have know the root u...

I'm writing a PCIe driver/module for a custom device. Since the device is hot pluggable, it can disappear at any time. Here how I setup up the pci_driver structure: struct pci_driver my_pci_driver = { .name = "my_pci_driver", .id_table = ids, .probe = "my_pci_driver_probe", .remove = "my_pci_driver_remove" }; But I don't know...
tar|gzip is wonderful, except files can get too big, and transferring them over network gets complicated. DOS era archivers were routinely used to create multipart archives, one per floppy, but gzip doesn't seem to have such option (because of Unix streaming philosophy). So what's the easiest and most robust way of doing this under Linu...
Folks, what is the best way to kill an established connection from the shell in linux? Looks like there are 'tcpkill' and 'cutter' tools available, however, on my gentoo amd64 tcpkill is disabled by the 'amd64' keyword and cutter, when used, prints an error "openning /proc/net/ip_conntrack: No such file or directory". Is there any ot...
I'm trying to install a prebuilt binary in a custom Android image. For that I have copied it to a new directory in prebuilt/android-arm/ with an Android.mk file similar to this one: LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) LOCAL_SRC_FILES := binary_name LOCAL_MODULE := binary_name LOCAL_MODULE_CLASS := EXECUTABLES include $(B...

I have a third party component which tries to send too many UDP messages to too many separate addresses in a certain situation. This is a burst which happens when the software is started and the situation is temporary. I'm actually not sure is it the plain amount of the messages or the fact that each of them go to a separate IP address. ...
Is there a way to to couple two streams (or file descriptors) together so that writing to one stream will also write to the second one? (C, Linux) Thanks. ...
In a previous post, I was trying to update the encoding for a download file from php. One of the suggestions was to run the unix2dos command before sending the file to the user. This works great when I run the command on the linux box, but when I try and run the command from php I get nothing. Here is what I tried: $cmd = "unix2dos -...
