I think you should use both:
1. chmod u+s allows your program to start with root privileges and gain
access to ports
2. Calling seteuid(getuid()) as soon as this access is gained, causes it
to give root privelegies up and continue to work under persona of
invoking user (so it can create files, owned by this user and, more
important, cannot read/write files inaccessible to this user), while
still have rights to access port.

__A cleaner table__
Type Win98 Linux Notes
============== ===== ======== =====
1.44 MB floppy A: /dev/fd0
Hard disk, EIDE /dev/hda Primary master
Part #1 C: /dev/hda1 Win98, 1.5 GB
Part #2 E: /dev/hda2 Empty, 1 GB
Hard disk, EIDE /dev/hdb Primary slave
Part #1 [?] D: /dev/hdb1 DriveSpace 3
Part #2 [?] H: /dev/hdb2 Host for #1 ?
ATAPI CD-ROM #1 F: /dev/hdc Secondary master
ATAPI CD-ROM #2 G: /dev/hdd Secondary slave
__Some notes, first:__
* I don't remember enough about DriveSpace to be sure
the above is accurate. Off-hand, I also don't know
of any way for Linux to read DS3'd data, so those
documents may be inaccessible to Linux.
* The above device numbers assume that all of your
partitions are primary -- none logical in extended
partitions.
* 'fd' means floppy disk; 'fd0' means floppy disk #0,
where 0 = first.
* 'hd' means (IDE/EIDE/UDMA) (hard) disk.
'hda' is primary master, 'hdb' is primary slave, etc.
These refer to the WHOLE DISKS.
'hda1' means 1st primary partition on primary master.
'hda5', if it existed, would mean 1st *logical*
partition on the same drive.
* Traditionally, installs create symlinks for the CD
drives, e.g. /dev/cdrom.
__About installing RH6:__
RH6 does not support UMSDOS, I believe. That would
allow one to install directly into a DOS directory.
Linux does not use 'drive letters'; it uses both
'device files' to represent the device, and 'mount
points'. Hence, you don't install Linux on E:;
you can remove the partition (or possibly just
alter its type), have a partition of the apropos
size and install there.
Or, more precisely, *at least two*; last I checked,
RH would not install without at least one swap
partition.
Rather than further duplicate the effort of others,
I'll point you to their work:
* Check RH's own site. They have an installation
manual online, y'know. *READ IT*.
* Check the HOWTOs and Linux Documentation Project
files. You can find 'em at
http://metalab.unc.edu/pub/Linux/docs
__Add'nl notes__
Yes, it's possible to install Linux on your
hardware, without removing any non-empty partitions
methinks (just the targeted one), although you'll
want to replace it with at least two.
Yes, you can use install a boot menu, via LILO.
That's rather well documented. You *might* find
that the installation program fails when installing
LILO, 'tho, so be prepared to have it instead write
a boot floppy, and then run LILO yourself after
boot.

No, this is a limitation of the file access API as implemented on 32
bit architectures.
It is also a limitation of NFS version 2.

Subject: Problems with ACER CD-R/RW CRW6206A
Date: Sat, 21 Aug 1999 03:54:53 GMT
I have an Acer CD-R/RW CRW6206A IDE in my Linux Redhat 6.0 box. I am trying
to create a data cd containing the Oracle install tar file so I won't have
to ensure I have enough disk space to untar it to install/reinstall Oracle.
I want to burn it under Linux so it keeps all the filenames in the correct
case and the permissions the same.
I'm using XCDRoast 0.96e and I have SCSI emulation turned on in my kernel.
Here's the output from cdrecord -scanbus:
[root@naboo /root]# cdrecord -scanbus
Cdrecord release 1.6.1 Copyright (C) 1995-1998 Jorg Schilling
scsibus0:
0) 'ATAPI ' 'CD-R/RW CRW6206A' '1.3A' Removable CD-ROM
1) *
2) *
3) *
4) *
5) *
6) *
7) *
[root@naboo /root]#
Reading is fine with the CD. When I begin the MASTER CD option, I create an
image file of the oracle install directory tree. Then, I write the image to
a CD-R. However, when it's done, it says there were errors. I cannot mount
the cd at all.
I setup the image type as Unix Rock-Ridge with the following ISO-Filesystem
options selected:
Inclide all files
Allow long (32-char) filenames
Rock Ridge with anonymity
Allow files beginning with a dot
Mastering the image to a file is fine. I can mount the file through the loop-
back device and ls it and everything. However, when I try to then write the
image to a CD, it doesn't work.
Again, I'm running under Linux Redhat 6.0 with kernel v2.2.11. SCSI emulation
is turned on and IDE/ATAPI is made as a module and not loaded. My system is a
P200MMX with 64 megs of RAM. My CD writer is the slave device on the secondary
IDE port. The partition I write to is my master disk on the primary IDE port.
The partition IS a Windows 95 FAT32 partition and not an ext2 filesystem.
I've read through the CD-Writing and CD howtos and can't find anything that
points to my problem.
If anyone has any clues as to what the problem is, I would appreciate it.
Thanks!

You should first try a kernel recompile. If your card is ISA based, compile sound
support
as module and use isapnptools. If it's PCI, then you don't need this.
If that fails, try the ALSA driver, dunno the exact URL, you can find it pretty
quickly ...
It should work in the end, OPL3 chipset is supported by both standard kernel
sound driver and
ALSA driver...

Sure. I use two ISA NE2000 clones in my firewall.
I installed each card - ONE AT A TIME - into the system, and ran the DOS
configuration program. I turned off the PNP and manually set the IRQ
and address. Different values for each card, of course.
Then I put both cards in, booted, and edited /etc/lilo.conf:
boot = /dev/hda
install = /boot/boot.b
map = /boot/map
prompt
timeout=50
image = /boot/vmlinuz-ne2k
root = /dev/hda1
label = linux
read-only
append = "ether=10,0x300,eth0 ether=11,0x340,eth1"
Run lilo, reboot, and two ethernet interfaces show up.
I use "make xconfig" to build the kernel on my main PC, which has the
disk space, memory, and processor speed to compile it quickly - none of
which is true of the 486DX33 firewall. "make xconfig" allows you to
save multiple config files. This makes it easy to maintain two very
different monolithic kernels. After reading about the hack into one of
the systems used for the recent internet security audit, I am very glad
that I do not have loadable modules enabled on my firewall.

You don't WANT /dev/st0 in /etc/fstab. That's for filesystems, which
work best on random access devices. Tapes don't normally contain
filesystems. What they do contain are one or more tape files in
sequence. Each tape file usually contains an archive, which then
contains a collection of hard disk filesystem files. Tape files don't
have names, permissions, or timestamps - just a sequence of blocks
beginning after a SOF (start of file) block, and ending with EOF (end of
file). Many tapes contain only one file. That tape file, like a zip
file on a PC, usually contains many other files.
You'll want to read up on "mt" and "tar" - which stand for "Mag Tape"
and "Tape ARchive".
"cpio" is more flexible than "tar", but perhaps a bit more confusing.
Get the basic operations running, and then you may want to look into
complete backup packages like "amanda".

Excuse me? I've been using 3C509's of all sorts with Linux for years.
The driver most definitely exists, it's in the module
