No, it's a lot better - as a mail reader. I personally use mutt but

No, quite right but having to use Netscape just to read POP3 mail (and not even
multiple accounts at that) is ridiculous. I have more than one POP3 account (like
the person who started the thread) so it's not much use as an Email client, and
isnt even very good at what it's main job is supposed to be - Web browsing!

As easy or hard as you make it. Just keep up to date with the
distribution that your using, the security lists (BUGTRAQ being the one to

I would have to say my definition would be: The user has "learned" the system
when he can accomplish what he set out to do. I.E, if it is an end user, he is
trained when he can log in and start the app(s) he needs to accomplish his work.
If it is a BOFH, then he is trained when he can delete user files, change logins,
grep the e-mail for interesting terms and redirect user output to null etc. An
admint is trained when he can fulfill all of the requirements of running a
system, I,E. instal/configure software, setup a system from scratch, fix any
problems that occur etc.

Subject: Difficulties making directories on root partition
Date: Fri, 19 Feb 1999 13:05:57 GMT
Either I'm the only one inept enough to do this, or people have been able to
fix it, but whenever I attempt to make a directory on my root partition
(using mdir), I get the message:
Can't open /dev/fd0: No such file or directory
Cannot initialize 'A:'
I can mount the disk using mount /dev/fd0 /mnt/floppy, but even when there
*is* a disk (which I can read in Linux) in the drive, I still cannot make a
directory on my root partition.
In case it's of any help, I'm running Redhat 5.0 running Linux 2.0.32

It is very risky to log in a root when you do not absolutely need it.
You can mount devices as a normal user if you add `user' to the list of
options for that device in /etc/fstab

Subject: Can someone tell me how to get LILO to update my boot floppy's kernel map?
Date: Thu, 18 Feb 1999 11:48:09 -0500
(Sorry for the reposts, this is the third day and I can't find the relevant
help in the HOWTO's)
I have a new kernel, but I have to use a boot disk at the moment, due to a
bios limitation on this 486. This is RH5.2, and I'm trying to get the boot
disk to load the 2.2.1 kernel I just built.
I have the 2.2.1 image copied over there, and I updated the lilo.conf on the
floppy's /etc dir, how do I run lilo to update the kernel map on the floppy,
not the hard drive??
In the floppy root, (/mnt/floppy) I have:
vmlinuz-2.0.36-0.7 vmlinuz-2.2.1
/boot
boot.0200 boot.b map message
(what exactly is the map file?)
/dev
fd0 hda6
/etc
lilo.conf
lilo.conf reads:
===============================================
boot=/dev/fd0
timeout=100
prompt
image=/vmlinuz-2.2.1
label=linux
append="mem=20M"
root=/dev/hda6
image=/vmlinuz-2.0.36-0.7
label=linux-old
append="mem=20M"
root=/dev/hda6
image=/vmlinuz-2.0.36-0.7
label=rescue
append="load_ramdisk=2 prompr_ramdisk=1"
root=/dev/fd0
However, the only choices at boot time are linux and rescue, which means
myexperiments with the various lilo switches have been unsuccssful. Help?

it can help to carry more precision. take two quantities of near
equal size and subtract them. if they are 80 bits rather than 64
bits, there will be 16 more bits left in the difference.
i think that libm exploits this somewhat and performs sloppier math
than would be needed for doing everything in 64 bits. the whole thing
is a larger problem than meets the eye.
the reasonable thing to do is develop a healthy disrespect for
absolute accuracy in your floating point quantities and design your
algorithms for numerical stability and construct your equality tests
based on epsilons. i think people expect too much from floating
point.

Right.

Several things:
a)
You're using the wrong program. Plain ol' getty does simply not work
for dialin lines at all.
b)
Setting up a dial-in line with Id 7 isn't a clever idea.
Change your /etc/inittab line to something like
S1:2345:respawn:/usr/sbin/mgetty -x 3 ttyS1
(assuming you do have mgetty in /usr/sbin) .
For details, see the provoded mgetty docs.

Samba on the linux machine is only needed if you want something on the linux
machine to be accessed by the Win98 machines - like disk space or a printer.
Samaba is not needed to make the linux box a router for you Win98 machines.
I work at home and have the current setup:
Pentium 100 (upgraded from a 486DX40)
- Slackware kernel 2.0.35
- name server for network
- diald (autodials internet when any machine asks for connection outside the
house)
- IPmasquerading (since I don't have static IP's)
- dhcp server for win95/win98 machines (central management of IP address info)
- print server (shares the HP660Cse color printer with everyone)
- shared disk space for rest of local network (8G hard disk here)
- A few other things not really needed but nice to have
Other machines are a P133 200mhz running Win98, PII-350 running Linux and
Win98, IBM Thinkpad 365 running Win95, and occasionally friends bring their
machines over for some work.
Since the p100 shares the printer and disk space, it's running Samba software
that allows the Win95/98 machines access to it's printer and disk space.
