Meanwhile I figured out the straightforward way: as root, simply do
pppd ttyS0 38400 # or whatever your line and speed
ifconfig ppp0 <localhost> pointopoint <remotehost>
on both hosts, and it works. No /etc/ppp/options file needed. Those
looking for slattach need look no further.
RedHat's ifup-ppp script lets you automate all this at boot time.
In /etc/sysconfig/network-options/,
(i) create an empty chat-ppp0 script; and
(ii) make up an ifcfg-ppp0 by analogy with ifcfg-eth0, but add two lines
MODEMPORT=ttyS0
LINESPEED=38400
This doesn't seem to be documented anywhere, either in the RH 5.2
installation guide, /usr/doc/ppp-2.3.5, or PPP-HOWTO, grr.
Note that ppp times out within a few seconds if there isn't a waiting
ppp at the other end. If this is a problem you need the "passive"
option. Unfortunately there's no PASSIVE option in ifup-ppp, so after
the line
opts="lock"
add three lines
if [ "${PASSIVE}" = yes ] ; then
opts="$opts passive"
fi
You can then add the line
PASSIVE=yes
to ifcfg-eth0, and pppd will then patiently wait forever for the call
from its mate. A similar hack to ifup-ppp lets you have bsdcomp (BSD
compression).

Did your ISP give you www.chew.nl, or something else? If the ISP gave
you something else, then you'll need to pay for and register
www.chew.nl. Go to whoever manages .nl TLDs (anyone know?). Then yes,
you can set it up as your hostname and be on your way.

The command "last" is also useful to trace the history of user logins,
including the IP or name of the host from which they loged in. Entered
as "last username", you can get a very long list of activity, entered
as "last -10 root" gives details of the last 10 logins.

Why not take a look at the various Samba/NT PAM modules?
http://www.us.kernel.org/pub/linux/libs/pam/modules.html
PAM is a layer of abstraction for user authentication; with the proper PAM
module, your POP3 daemon should be able to authenticate against the NT Primary
Domain Controller.

Reply-To: [EMAIL PROTECTED]
Hello there,
I've setup a Linux box with 2 network cards (3Com ethernet and IBM
Tokenring).
Working through these cards works ok (i've setup the appropiate routes),
but here is my problem:
My DHCP-server is running on the Ethernet-segment.
I'd like to have the TokenRing machines getting their IP-addresses from
DHCP as well, without installing a DHCP-server on the TokenRing segment.
I've fumbled with ifadm but with no luck.
Here is (part) of my network:
ETHERNET SYSTEM TOKENRING
10.0.2.1 DHCP none
10.0.2.1 SERVER1 none
10.0.2.51 CLIENT1 none
10.0.2.52 LINUX 10.0.3.52
none CLIENT3 10.0.3.53
Connection from CLIENT3 to SERVER1 goes OK, but only if i
setup a fixed IP-addres.
TANX for any advice/help.

I have PPP talking to my ISP under RedHat Linux. Everything seems to work
except....
If I don't use the connection fast enough (21/2-3 minutes), it disconnects.
However, if I use it for anything (ping, traceroute, ftp, telnet,...) it
seems to work as long as I am using it. Is there a timeout parameter
somewhere that I missed?

You could always edit your XF86Config file and add the following line in your

Then be sure to have a specific Resolution in there that you want for that Color

No. nfs is for mounting other UNIX shares. It's a different program
entirely.
You want to use smbmount.

smbclient is for looking at the share. smbmount is for actually
mounting it. You don't have enough slashes because backslashes ("\")
must be escaped. You do that by preceding it with a backslash, so \
would be \\. But no matter, because you can use forward slashes. So,
smbmount //win95box/c will do the trick.

I have on my Linux box two segments.
each on a ethernet card, 192.168.3.x and 192.168.0.x
Almost all users use win9x
Users on each segment can see ech other on 'networking neigborhood' or
in the tree by 'exploring'.
As you know it is done with netbios over tcp/ip
Unfortunately the users from x.x.3.x do not see users from x.x.0.x
I have to route netbios over both networkcards. Samba does not fix
everything for me (as I first thought)
Does anyone of you know how to fix this?

Given that the cracker must have had root access to do that, it would not
have mattered whether the ftpusers file lists names or UIDs. He could have
circumvented that, too. In this particular case, *nothing* could have
helped.
So the particular details of this attack do not seem to be salient to the
more general question about restricting ftp access by certain users. That
is controlled by the contents of the /etc/shells and /etc/ftpusers files,
not by the contents (or lack thereof) of the password field in
/etc/passwd.
I don't understand why the poster thinks that this is "less secure".

Subject: Linux Server + Win 9x Clients - Security???
Date: Mon, 18 Jan 1999 21:31:30 -0500
Greetings all,
Trying to avoid putting NT server on my main server machine.... I have a
small network of a total of 7 computers. The users of these computers are
not going to be inclined to learn Lunix, or to give up their pretty MS
Office, or Quake, etc...
What I want is a network logon similar to what you get when you run an NT
Server as a primary domain controller.. When you turn on the computer you
get the pretty "Log on to the Network" box with no way to get into the
computer at all without a username/password being authenticated by the
server...
I was reading one of my NT books today at work when a co-worker and I got
into one of our spirited Linux-NT debates. I agree that I'd rather be
running Linux, but is there a way to lock down Win 9x clients so they can't
get in at all as if I was running a NT4 Server? Can Win9x clients be told
to log onto a NT domain, even though it's really a Linux box like my
coworker says?
Pointers to relevant FAQ's, HOW-TO's, web pages, etc. appreciated.
Followups to [EMAIL PROTECTED] also appreciated.
Thanks in advace...
===Andrew

No problem with my Sportster 56K Voice Modem, except no voice feature in
Linux.
