Server OS
Hi guys,
I never thought I'd be here. I've got my MCSE and I was a die hard Windows guy. I've been working with UNIX and Linux sense the middle of summer. I'm looking for server OSs. UNIX or Linux, preferribly the easier of the two. MY goal is to get UNIX and Linux into the company I work for now. I'm an admin for a company and I feel Windows is very expensive and so on, I'm not bashing. My question is, is there any free server side Operating Systems, I have to do this with my own money and research it before I can bring it in. I've looked all over for Linux and finally bought if off ebay for 2.00 bucks. I feel like I' stealing. Also can anyone refer me to a good reference book or website that has an overview of installations and what not. I've had Red Hat 8.0 (I think) installed on a w/s at home for quite sometime. Hope I didn't ramble for to long. I look forward to talking with many of you.
Thanks, Craig

getuid32
GETUID(2) Linux Programmer's Manual GETUID(2)
NAME
getuid, geteuid - get user identity
SYNOPSIS
#include <unistd.h>
#include <sys/types.h>
uid_t getuid(void);
uid_t geteuid(void);
DESCRIPTION
getuid() returns the real user ID of the calling process.
geteuid() returns the effective user ID of the calling process.
ERRORS
These functions are always successful.
CONFORMING TO
POSIX.1-2001, 4.3BSD.
NOTES
History
In UNIX V6 the getuid() call returned (euid << 8) + uid. UNIX V7 introduced separate calls getuid() and geteuid().
The original Linux getuid() and geteuid() system calls supported only 16-bit user IDs. Subsequently, Linux 2.4 added getuid32() and
geteuid32(), supporting 32-bit IDs. The glibc getuid() and geteuid() wrapper functions transparently deal with the variations across ker-
nel versions.
