I have just got login authentication going through the netware
server (PAM is cool). What I really want to do is allow users to
download their mail from the linux box, using their netware password. I
havn't been able to find any documentation on the subject and was hoping
someone here could help me.
Another thing that would be very nice would be if either the user could
download mail without having an account on the linux box, or have an
account made up when the user first attempts to log in.
Thanks in advance
Sean.

I agree -- the right tool for the right job. I have both my PCs (dualP6 and
single celeron) networked, and each is dual boot. When I have company to
play network games, etc, or use some client I need for work, I'm on Windows,
and otherwise I'm on linux.
>Too many people seem to think that Linux and Windows are mutually exclusive.
Well, so long as most games (that's two or three heavily enjoyable hours a week
for me) run exclusively on Windows, it will be a part of my life. And as long
as my scanner is unsupported on linux, same thing. I can hack a few things as
far as devices go, but I wouldn't know where to start with that.

Possibly the most important feature of a naming theme is that it be
highly extensible. Even a fairly "large" fixed set like the 100+
elements of the periodic table is likely to run out eventually (most
sites can buy computers faster than physicists can name new transuranic
elements) and using the Seven Dwarves is just *asking* for your boss to
tell you to buy machine #8 (which might be a feature ;-).
Some themes I've seen used:
- Stars. Don't use planets; you'll run out really fast. Even if you
include moons. There are LOTS of named stars.
- Planets, as long as you use *fictional* ones. First, the collective
output of all those SF writers has a many year head start; second,
there are new ones being invented regularly. Fictional stars work
too. Fictional places in general, actually, work quite well. (With
only a few machines, you might even get away with using only one
author's books, at least for a while.)
- Fictional characters. Again, for small groups you can use one author
or one series; for larger ones, you'll have to branch out. This
leaves some room to match character personality with machine
"personality", though. Fictional AIs/robots is a common theme.
- Fictional (or legendary) ships (either waterborne or space; the latter
may overlap with fictional AIs). Again, though real ships are an
option (and often provided the names for fictional ships anyway) your
computing budget is probably going to be spent on more units than the
USN's shipbuilding budget is....
(For those who haven't seen it yet, RFC 1178/FYI 5 covers the naming
topic fairly well, but *doesn't* have much suggestion for what themes to
use--just that they're a Really Good Idea.)

Your routing table does not have a default route. I'm surprised that you
are even able to ping with ip numbers.
Since you are probably alwasy being allocated an ip address from within
the same scope and that that scope probably has only one router, then you
could set up a static default route to that router.
If your windows connection works, then look at the routing table ("route
print") and try to determine what the default route is. Then use those
same value in linux to set up a default route.
Otherwise, you could look into the "-c" option of dhcpcd.
Hope this helps,
Luca

Subject: PPP keeps disconnecting after a few seconds!
Date: Tue, 16 Feb 1999 23:03:22 -0800
I'm having some problems using PPP with Redhat 5.2. Specifically, I dial
up via minicom (yeah, I know there's easier ways to do it...) and give my
ISP my userid and password. I then get back some PPP gibberish. Then I quit
minicom (although I don't hang up the phone). Next, as root I type 'pppd'.
But then if I try to connect to a remote site, I get an error message saying
it couldn't connect, or something like that.
I've checked and rechecked my /etc/ppp/options and /etc/resolv.conf
files and they seem okay. So, I tailed /var/log/messages and noticed this:
"CCP: timeout sending Config-Request". Could someone tell me what this
means, and how to solve it?
Oh, if it helps, my /etc/resolv.conf file is:
search teleport.com
nameserver 198.108.254.11
and my /etc/ppp/options file is:
0.0.0.0:
/dev/ttyS1
lock
crtscts
defaultroute
asyncmap 0
mtu 576
mru 576
The really strange thing about this is that this worked fine several months
ago, with Redhat 5.1

Other machines have more mundane names like the user, or a particular

Actually, that last one is old enough that it was the UUCP name for the

Dear Group,
Regarding my problem, I forgot to mention: I am pinging with IP
addresses,not domain names, so it is not a name resolution problem. DNS
name resolution wouldn't work at all since I can't even reach the
nameservers of the ISP.

I don't understand. Why do you need reverse DNS to ftp? I ftp thru a
masquerading gateway connected to a cable modem all the time. Only one site
I upload to (members.home.com) has problems with it, and using passive mode
fixes that. Everything else works transparently.

I downgraded to 4.08. Still freezes now and then, but a bit less buggy than
4.5.

I do a lot of surfing (too much), and I've never felt the need for any
plugins except for Real Audio. I suppose my interests are very different;
I'm generally looking for useful info.

I also read a lot of news (too much), and would seriously hurt anyone who
tried to take away my copy of slrn. News is about reading text and writing
text (OK, except for porn), and I like to do that as fast as possible.
To me that means a text-based reader like slrn.

The manpage for gethostname(2) under RH5.2 says it invokes uname(2), and
that looks like it queries the proc filesystem. That value is probably
set during the boot process.
