Not very familiar with this list, if i violate policy by this post excuse me. Hi, am an entrepreneur of a small business, we make industry specific client server software . Its interesting work, and requires lateral thinking. I have the ideas and the team processes them. we have a VB, person full-time, a VC++ consultant, we had a genius Linux/PHP admin/programmer but he left.

Thx a lot... It works... I have to put lib path into /etc/ld.so.conf and run ldconfig. It compiles now perfactly ok...

Colored Prompt and other tweaks
by Nikhil Joshi 24 Jan '02

24 Jan '02

Hi! I was wondering how [ OK ] is displayed in color. I found the /etc/rc.d/init.d/functions file. I got the 'color code' and assigned PS1="\\033[1;32m$" |----- my prompt Now my prompt appears in green color!!!. I would like to know what do those numbers and symbols mean. I figured out that 32m stands for a color and changing the value changes the color. I found out another tweak by which one can have a message on the console while all the commands scroll below it. Here is the exact command. $ clear;echo -e '\033[018;25r'; cat ascii_logo_file I use this in rc.sysinit to dislay a logo while other stuff scrolls below it. Kinda looks good ;-) Again I would like to know what does the stuff mean. BTW has anyone used a kernel patch which shows a welcome screen ? I've found LPP and I'll be checking it out soon :-) -- Say no, then negotiate. -- Helga

DCOP Server Ka Funda

Linux is not reliable . Windows Still rulez
by Nikhil Joshi 24 Jan '02

24 Jan '02

Sorry for posting without subject . The thing is I'm very frustrated for putting my trust on Linux :-( OK I had enough of Linux (period) I've been using Linux for almost 2 years now. After getting bored of Windows I decided to remove it from my PC.I was running only Red Hat Linux 7.1 when I had a major filesystem crash. I even lost some of important data. One of my friends suggested that 7.1 had a buggy kernel and I should switch to 6.2 I installed 6.2 and everything was fine until today... The boot process 'dropped me to a shell' and advised me to run fsck manually. I obliged. Out of the blue I got a truckload of messages telling me that something was wrong and that should it fix it ? Amazingly the only answer was yes.I continued pressing 'y' for about 5 mins and then the ordeal was over. I logged in just to find that my ncurses libraries had been deleted ! And horror of horrors: my entire rpm database was gone... I did not want any more surprises. Being frustrated I decided to give myself a break. I removed Linux and now I'm running good ol' Win 98 :-) Anyone reading this please keep in mind : Curse Windows , Hate Windows ,Kick Windows but never and I say *never* remove Windows. It is the only thing that works for you (period) _________________________________________________________ Do You Yahoo!? Get your free @yahoo.com address at http://mail.yahoo.com

[OT] - Linking of an absolute executable file ???
by Kunal Gangakhedkar 24 Jan '02

24 Jan '02

Hi Guys, I'm having trouble in understanding the theory behind the compiler strategies for generating absolute object files. Pls. someone guide me on this topic. The main concern is : Linux kernel is compiled to start loading from a particular memory address (cf. TLK - The Linux Kernel) 1. How is this achieved by the compiler??? 2. How do we decide from where to start load an absolute object file in memory, i.e. how is the memory address of the entry point of the code decided??? 3. If this depends on the locations of the IVT, GDT etc. then where to find all this information i.e the sizes of all these memory tables??? 4. Are there anymore issues involved in generating absolute object files?? Pls. help me in this aspect - more detailed information - the better for me. Kunal ------------------ In most countries selling harmful things like drugs is punishable. Then howcome people can sell Microsoft software and go unpunished?

When I started out, I was averse to the command line too. But as I began discovering commands for things that went click-click, I found myself using the command line more and more. The reason is simple - it's easier to issue a command than fire up a GUI, sift thru the tabs and buttons et al. Say, you want to add a user to a new group. How'd you do it in GUI? Fire up Linuxconf, expand the trees till you reach the users area (I've forgotten what Linuxconf looked like, so it's a somewhat inexact reproduction), click on that user and then in his/her property sheet, specify the group somewhere. That done, you click the "Activate" button and then "Quit" hoping that things went fine. Same thing on the command line: # usermod -G <group>[, ...] <user> There's a command - apropos - that searches for the supplied keywords in short descriptions of all the entries in man pages. So, if you're looking for disk management commands, you can do: $ apropos disk and get a list of commands that have the word "disk" in their descriptions. I don't say that GUI is bad. The user should figure out when to use what tool. As a rule of thumb, use a GUI tool when you are going to use a majority of the features it offers. So I may use LinuxConf when I get down to configuring my system after a fresh install. But not for the occasional tweaks and mods.
