I was installing a binary Linux application on Ubuntu 9.10 x86_64. The app shipped with an old version of gzip (1.2.4), that was compiled for a much older kernel: $ file gzip gzip: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.0.0, stripped I wasn't able to execute th...
Here's the deal. I logged into a Linux box (CentOS, but that shouldn't matter) as user A. I had to build a program as user B, so I started up a terminal shell, logged into that shell as B, and built it. When I try to run the app, I get this message: "connect to ":0.0" refused by server" Most likely because the current X Windows session...

I have a project where I have to perform some mathematics calculations with double variables. The problem is that I get different results on SUN Solaris 9 and Linux. There are a lot of ways (explained here and other forums) how to make Linux work as Sun, but not the other way around. I cannot touch the Linux code, so it is only SUN I can...

I can't make System.Linq (aka. Linq-to-objects) work. I am running MonoDevelop 2.2.1 in Ubuntu 10 Lucid Lynx with Mono 2.4.4. They advertise in their site that they implemented Linq, but I can't even find Enumerable.Range or .ToArray(). What's wrong? ...
Given a filename in C, I want to determine whether this file exists and has execute permission on it. All I've got currently is: if( access( filename, X_OK) != 0 ) { But this wont search the PATH for files and will also match directories (which I don't want). Could anyone please help? Edit: As an alternative, seeing as I'm running e...
I'd like to setup a cron job that checks e.g. every 24 hours to see if a 'find' command like the one below (which checks for malicious shell hacking scripts) has any results: find /home/username/public_html -type f -print0 | xargs -0 egrep '(\/tmp\/cmd(temp)?|SnIpEr_SA|(c99|r57|php)shell|milw0rm)' And if there are any results, then I ...

I'm working with an embedded Linux deployment and am using a cross compiler tool chain that doesn't compile I2C library function calls. How do I determine the precise versions of the libraries on the system so that I may rebuild the tool chain?

I wrote a C++ application (running on Linux) that serves an RTP stream of about 400 kbps. To most destinations this works fine, but some destinations expericence packet loss. The problematic destinations seem to have a slower connection in common, but it should be plenty fast enough for the stream I'm sending. Since these destinations a...
