I have used the Software called "Dave" It works great on a LAN. You might
want to try it also.. the major problem is that they don't all "speak the
same language". If you are running Samba then I suggest providing the
Apple Box with SMB support also. You will also be able to brouse your Win
9X box using "Dave". there is a free trial download that there web
site...(I don't have the URL currently). Good Luck.

Did you try the auto configure option from the config utility?
Because I had the same thing.
For me it was a IRQ conflict.

Hi!
We have a Linux-Server running as a Gateway to our ISP by Modem-PPP.
We installed Squid and it works.
But there is one Problem:
If the ppp is down and I'm trying to access a Page, Squid generates the
message "DNS lookup failure". That's ok. But when I start the ppp and
try to access the page again, Squid shows me the same message again
because he cached the message.
How can I set up Squid not to cache the self generated error messages?
Thanks

bing instead of ping is a simple first step. To go all the way
you might want to re-link your kernel for some net
snooping hooks.

Subject: Reverse-SSH Connection?
Date: Sun, 31 Jan 1999 16:46:54 GMT
I have a firewall at work, which allows me outgoing connections to my home linux
machine via ssh. I cannot do the reverse connection, however, since nobody wants
to screw around with the firewall, and punch a hole for ssh, or handle it on the
firewall.
I have been able to set up a simple reverse telnet connection, by:
slogin mellor.home.net -C -l qwerty -R3456:machine.company.com:22
However, I want to be able to forward X over the reverse-SSH connection. How do
I do this? My home machine is a RedHat 5.1 system, and the company machine is a
Solaris-2.5.1 system.

No. Don't do that. When you get a cable connection, you are given a single IP
address on an ethernet. Consequently, the rest of the network cannot be allowed
to see your internal network machines (and they won't route then unless you are
stealing somebody else's IP address too).
Set one of the machines up as a firewall, providing NAT (Network Address
Translation) services for the others. Linux Masquerading works fairly well for
this, as does BSD NAT, or NT/Win95 Sygate (small $).
You'll need the firewall to be functional, too. When you have a high-bandwidth
connection, you also get a lot of attention from crackers who have a low patience
level, and prefer to crack high-bandwidth sites. Many of these jerks are
actually based on the cable networks, seeing as a student can actually afford
this type of connection.
Having said all that, here is a web page dedicated to setting up ComCast
connections with Linux:

Godd Luck! Cable is the best bang for the buck out there right now!

Hi,
I just asked this question over in comp.os.linux.questions before I saw
this group so I'm reposting this here.
I've asked this question for what seems like a year now in many places,
mostly IRC, without any luck. I hope you fine people can lend a hand.
:-)
I'm trying to network a Macintosh and my Linux (RedHat) box via TCP/IP
without any luck. For the past year I have had them connected via
Appletalk (netatalk) through my ethernet card without problem. I just
can't seem to get the TCP/IP working. Neither computer will see the
other.
How am I supposed to do this?
I figure my cables, hub, and hardware are all fine because Appletalk
works.
I'll be honest, I don't know a whole lot about routing and TCP/IP. I'm
sure its just some stupid little number set wrong someplace, or
something I forgot to install. I don't really want to go out any buy a
$50 Networking book just to find out how to do this one task.
Thank you for any help, have a good day!

Michael,
Does your ISP use PAP? You might want to check out the Linux PPP HOWTO (I
think v3.0, 31 March 1997 is the most recent) and configure all the files
manually. I found this HOWTO to be most useful, but read as many things as
you can. By configuring the files manually, you'll know exactly what is
going on instead of using the Network Config menu.
Check your chatscript also. If you are using PAP you likely will not need
to send login and passwords as your pap-secrets file contains this info...
Good Luck. Here's where you want to look.. /etc/ppp/

You're cable modem can't act as a server... it is not that intelligent.
You should have a machine that will serve as a proxy for your internal
network going
to the internet and will act as server.
Picture:
your internal pc --->HUB---->proxy_server---->cable_modem--->internet

or socks http://www.socks.nec.com .
BTW, try to browse the postings around here...
a lot of people have posted/answered this type of questions already.

You need to make a distinction between GTE the Telco and GTE the ISP. It
is the ISP that is managed by MS bigots, The Telco just shuffles bits
around for dollars. Unfortunately, when you call GTE they do not make this
distinction clear.
The answer is not to get DSL directly from GTE. Got to:
http://www.gte.com/dsl/partisp.html
Make a few phone calls. You will find most of the ISP's do not care what
opsys you run as long as you understand Linux is not officially supported.
If you can configure a NIC card for IP you can use DSL. I am signing up
with California Prime Line (http://www.cpl.net/) for 384k/384k service with
GTE as the carrier. I did not hide the fact I am running Linux on the
connected machine.
GTE is s regulated monopoly. Once they offered DSL as a commercial service
they were required to offer it to any company that wants to take advantage
of it. GTE is also bound (currently) to provide this service to all
customers at the same price regardless of whether they use GTE as an ISP or
not.

I can well imagine that Bill Gates and his allies in industry might
fantasize about turning all those Linux nuts into desparicios. That might
even be possible in some countries where a readily bribable military regime
rules. However, in some other countries too many Linux users are also
libertarian gun nuts like Eric Raymond. We may not be able to stop them,
but we can raise the threshold high enough that we can't be stopped in
secret :-)

Subject: Linux (2.0.35) TCP "hangs"
Date: 31 Jan 1999 16:29:02 -0000
Reply-To: [EMAIL PROTECTED]
Hiya,
I'm wondering in anyone can help me with a small problem I have on my
machine. I'm running Kernel 2.0.35 (okay, old, I know, but I had problems
with BIND 8 and 2.0.36...so...)
Every so often, my machine acts as if the TCP layer "hangs", and forgets
how to route, or something. The symptons are:
- telnet to any port on the machine results in telnet hanging
at the "Trying <blah blah blah>..."
- all connections appear in netstat in the SYN_SENT or SYN_RECV
state.
- no outgoing TCP connections can be made to any machine, including
localhost
- incoming TCP connections from an external host can still be made
- the IP layer is still working (ie, I can ping external hosts)
- host masquarading still works (it's at the IP layer)
- existing connection still work
No changes have been made to any of the network configuration files. This
problem occours intermittently, but when it happens it is always shortly
after a PPP connection has been initiated.
Any sugestions?
TIA,
Chris...
