>At my place of employment, we are using Linux to provide Internet
|
|
services for hundreds of users. These services include TACACS (dial-in
|
|
modem user) authentication, web page hosting and proxy caching, as well as
|
|
SMTP and POP services. In addition, we are using Linux to provide NFS
|
|
services, and also for providing and mounting SMB-protocol
|
|
(WfW/Win95/WinNT) file & print and FAX services using the Samba
|
|
package.</P

|
|
>At home, I use Linux for my personal needs, such as Internet
|
|
services, software development, and of course game playing (seeing Quake
|
|
II running on a Linux box is a thing of beauty)! One of the things I love
|
|
about Linux is, no matter how hard I pound on it, it does
|
|
<EM

information). This distribution includes all the necessary software for a
|
|
full-blown unix system -- shells, compilers & interpreters, networking
|
|
support, the X Window System, and all Internet services (eg. Mail, news,
|
|
web server, telnet, etc.). The distribution comes standard with Linux

kernel 2.2.12.</P

Red Hat 5.2, running in another office location. It provides networked

secondary DNS services. Unfortunately, this box is over 50 km away from

where I usually work, and therefore it's left pretty much on its own --

yet this baby is really my pride and joy! Here are some specs:</P

>Having an incredible 24+ Gb of available storage space, with

redundant storage configured as a hardware RAID5 array is a humbling

feeling. The Mylex RAID controller works great, and I would not hesitate
|

to recommend it to others seeking a hardware RAID solution! (If you are
|
|
interested in configuring your Linux system with a RAID array, see

details.</P
