I have sendmail setup with sasl and multiple domains.I'm sure there is an easy fix for this but I can send emails to anyuser@<anyofmyvirtualdomains.dom> and it will be accepted. I'm just trying to cut down on any confusion that may occur later. Is it possible "restrict" or classify a user into a particular domain?

i figured lspci is a start but there has to be more info somewhere to find the exact needs of the laptop.

I am fairly new to ubuntu. I have to compile some libraries under ubuntu in a directory other than the default directory and then get the shared object libs (.so) libs for building some custome kernels. I created a directory structure as follows:
/home/username/build-target
/home/username/src-<libname> =>here are the source files for the lib. I need to compile
Now I create a directory /home/username/src-openssl and download the source code and untar it under this directory and issue ./configure --prefix=/home/username/build-target --exec-prefix=/home/username/build-target and then make and make install. I was expecting that the shared object libraries created (.so) files should have gone under /home/username/build-target/libs, however I just see only libssl.a and libcrypto.a and not .so files under the build-target/lib directory. For grep also I did the same thing as above however I don't see any lib directory created under build-target directory as I was expecting.

I would like to try and optimize my kernel a bit. Since I am doing this on a fresh install, I don't really care if the os gets bricked in the process, and I am sure I can bring it back if I can boot into a recovery console from the old kernel. So, I followed thispost. I patched it and copied and edited a config file from /boot/, saved it as .config, I tried it several times with both removing and not removing /debian and /debian.master directories from the source, yet I always get the same error when I run "make oldconfig".

I'm trying to compile some of the gnu utils (the version on some of the computers I work on are terribly out of date). The issue is that many machines share the same filesystem, and I'd like to not have a different executable for each machine. Anyways, I've read that
./configure CC="gcc -arch i686 -arch x86_64 " --prefix=/home/user/bin
should work. But of course it doesn't. apparently -arch is not an argument accepted by gcc.
I am trying to cross compile a package from source for an embedded arm board, however I am not having much luck creating an arm binary.
After running make, this is what I get:
I'll try to make this short, esp because I don't know if this is the right place to discuss a 3rd party program like "Avidemux" I'm running the latest version "2.5.4" or so. It started giving me this problem where no matter what settings I give it, the resulting files are so small it results in an error after almost a day of encoding. ( "XYZ" was NOT saved correctly , for example.) One day I noticed the quantisizer was at max, peaking at 48-50...which made the files tiny. So, I can avoid this sort of, by limiting the maximum and minimum quantisizer in the configurations. Problem is, I have no control over target size or bitrate this way..and sometimes the results are still unplayable.
Naturally I've uninstalled and re-installed several times, and recompiled the x264 codecs using this guide: [URL]... So, I downloaded the Tar.gz of the previous version i was using (Avidemux 2.5.3), the last known thing I know that worked for me...but I have no idea how to install it. I've tried running "Make" / "Cmake" In which I was told that an "in-tree-build" was detected. And trying to run the included "bootStrap.sh" results in : "Permission denied" or file/command not found. I don't think their old releases come in the default Ubuntu/Unix package "deb" right?
All these could be small errors on my end, but It urks me. In between reading up, and everything else that needs to be done in a day, I could have been done by now... Does anyone know where i could be going wrong?
I'm following the instructions here, to compile OpenSceneGraph that I got on DVDs purchased from Curtis Olsen. The instruction for this step goes like this.

Its about CFLAGS and -O2, and options like -march=<your architecture>. There are things I am just not sure about eg - this PC has a Intel i7, which has a wealth of powerful instructions developed since 'i386', that the gcc complier might be able to compile for - if we tell it! Where are the default options kept? Even supposing one decides not to mess with Ubuntu defaults, how does one locally compile a program, optimized for the CPU, overriding the defaults? How does one even tell if the 64-bit version got installed? In my case, it was provided by others. clicking System -> About Ubuntu can be surprisingly opaque on this little detail, even though you get the chance to choose at the site.
