Subject: 3C574 PCMCIA NIC connectivity
Date: Thu, 27 May 1999 17:37:59 -0700
Hello all,
I have a Toshiba Tecra 8000 dual booting with WinblowZ 95 and RedHat 6.0. I
have finally gotten the pcmcia module working and seeing the 3C574 NIC that
I have, but it will not connect to the network and I cannot get a DHCP
assigned address. Here is what I have done so far:
The first thing that I did was to change the order of the startup in rc5.d
I change it so that the pcmcia service starts before the networking service.
Now eth0 is binding to the Card and the link light is turning on, but when I
have it set to get a DHCP address it says that it is attempting to get the
IP information for the card and times out. BTW I have been using linuxconf
and netcfg to configure the card. When I use the IP address that is
dynamically assigned while in Win95 the card initializes fine but the only
things that I can ping are my own IP and the loopback address. The lease
expiration on the DHCP server is set for about 48 hours so I'm not worried
about another computer taking my IP. I have entered all of the gateway,
subnet, and DNS information into both linuxconf and netcfg and it seems like
everything is working OK (no error messages), but I cannot get any
connectivity. One thing that worries me is that when I use lsmod the
3c574_cs is loaded but not being used by anything.
I know that the 3C574 driver in the 3.0.9 pcmcia package is experimental and
this may be the reason that I cannot connect, but I'm wondering if there are
any configuration settings that I may have missed. Any help would be
appreciated. Thanks in advance,
Dave Wilde
P.S. - Sorry about the vagueness of this post I am using Winscrewed95 right
now so I cannot get the exact linux settings, if you need them to help send
me an e-male and I'll get them for you. Thanks again.

I need some advice on setting a home network. I need to connect two
powerpc's and two ibm pc to a network and alltogether on an adsl or modem
connection.
Is it possible to have a hub in the basement and run cables from there to
different places in the house? Or I have to have a server to do this? (I
mean is it possible to split the connection to 4 as it comes from the
modem... or I have to have a server to do this job even if I have 4 distinct
IP addresses?)

Hello!
Just one advice - change your IP addresses on "private" network to the
"private" range of IPs:
192.168.0.0 - 192.168.255.255.
Good luck!

It's possible this is a Winmodem, which is useless in Linux.

Date: Thu, 27 May 1999 20:54:55 -0700
I have linux (RH 5.2) and Oracle 8 running on my old Dell. When I
installed, I thought I would never want any networking (ok, ok I know...)
Now I have a real desire to use my win98 box to telnet into the linux,
mainly for convenience (and maybe I'll learn some networking....). What are
my options? I use UNIX and Oracle at work as a programmer, but I am not a
networking expert by any stretch, nor am I am linux expert.
Should I just buy a couple of ethernet cards? What kind? Do I need a hub?
What drivers/packages should I install into the linux box? I'd like to do
it for under a $100 bucks.
I tried using a null modem cable and pppd, but got nowhere fast. It didn't
promise to be real fast anyway, just cheap.
Thanks for any help I receive.

Date: Thu, 27 May 1999 12:27:46 -0700
Hello!
Frame relay is a cloud network, which means that you are sharing your
bandwidth with as many users as are connected at any given time.
You have 128K connection to that cloud and not to the Internet. So your ISP
is trying to fit all of the Frame users via their link to Internet. Also
your ISP does not own anything on Internet, they are reselling Internet
services from some other ISP.
That's why it's so slow.

I f yes, how?
Also, I want to know what must I do to have a job ID number

Linux RH 5.2
I'm trying to connect to my ISP using pppd and boy I tell you, it's been ...
well I won't use those words here. :-)
1 I'm looking at the traces and I see LCP negotiation and both agree
2 Then I see PAP authentication (with good user/pass) and the host comes
back with an authentication ack
The string in the Ack is empty ("").
3 Then after about a 5 second pause, LCP sends back an authentication
failed and request to disconnect.
Why? I've tried various options and settings. Is pppd looking for something
in the empty string? Does CHAP need
something?
Thanks,
Andrew.

I don't think RH 6.0 has anything to do with it.
(I got PPP running on RH 6.0 right away)
I haven't been able to get KPPP to work though,
so I'm using "ye good'ol" script based method.
First of all I suggest you add the debug option
to pppd. BTW: are you using PAP ? Anyway, here
is my setup (from the top of my head...I'm not
sitting in front of my home machine).
--- /etc/ppp/ppp.up ---
#!/bin/sh
/usr/sbin/pppd /dev/cua0 57600 debug file /etc/ppp/options \
connect /usr/sbin/chat -v -f /etc/ppp/
=======================
--- /etc/ppp/pap-secrets ---
YOUR-USER-ID * YOUR-PASSWORD
============================
--- /etc/ppp/options ---
user YOUR-USER-ID
defaultroute
============================
You may need to add some more options, see the pppd man page.
Study the output from the ppp.up script (and /var/log/messages).

I recommend looking at the Linux Router Project at www.linuxrouter.org.
I suggest you join the mailing list. It is not as much of a mystery once
you get a system working. The ftp site for www.linuxrouter.org has a "idiot's
image
of a working disk. I have a system up and running with no hard drive (only a
floppy is required) on a 486DX-80 with 16M RAM (12M is required minimum). I
don't
even have a keyboard or monitor attached, run a fan on top of the CPU or
internal to
the computer's power supply (no noise at all; just a box). Keith

There are various ways to do this; setting up a Linux gateway machine
is the one I like best. In addition the Linux box can be a file
server, database server, print server, web server, etc.
See http://metalab.unc.edu/LDP/HOWTO/HOWTO-INDEX-3.html to get some
ideas as to the possibilities and challenges. :-)

I would look for two cheap Ethernet cards with both coax (10base2) and
twisted pair (10baseT) connectors. Make sure to get cards supported by
Linux; non-plug-and-play is probably better too. Coax is easier to hook
up if the systems are in the same room; no hub or cross-over wiring
needed. Later you can expand by switching to the 10baseT if needed. You
won't need $100 either - I got 2 NE2000-type cards, 25' of coax with
connectors, and 2 terminators for about $65 - and that was 2 years ago;
you can do a lot better today.
