If the machines are connected direct, there cannot be any collisions. Two wires
are for transmit and two wires are for receive. This is why you need a crossover
in the wires. So the computers can be connected:
Computer "A" Computer "B"
Xmit ---Rec
Rec---Xmit
There cannot be a collision. One computer the Xmit is connected directly to the
Rec and the Rec is connected directly to the Xmit.
With a Hub, all the Xmit's are connected on the same side, and all the Rec's are
connected on the same side. It's up to the Hub to allow only one Xmit or Rec at
a time between one set of computers. If two sets of computers try to communicate
to the same computer at the same time, there is a possibility of a collision.

What about the situation where you are connecting together two machines

for collision detection? If a hub detects a collision, it sends out a signal
which causes the cards to retransmit...Otherwise packets are lost?

No, a hub is designed to to take packets and distribute them as best as

Perhaps I am wrong, but I thought a hub simply made the appropriate
electrical connections. That is, to my knowledge, a hub does not
deal with packets, only with electronics. (If it deals with packets
and distributes them to their destinations appropriately, then it
is probably a switch. Granted, one could say "hub" and mean
"switching hub", but in those context (microhubs) that's probably
not the idea.)
So, in my understanding, you're *just* as likely to have packets
collide on a two host network whether or not you have a hub.

Subject: Firewall and IPSec
Date: Thu, 14 Jan 1999 19:50:08 GMT
I have a private network with 5 machines (2 are NT, 1 is Win98, 2 are Linux
(RH5.2)). I have this network connected to a Firewall, also running RH5.2.
The firewall connects and masqerades to a cable modem to the Internet.
Everthing works great and I'm a happy camper.
Now work has implemented an Extranet host using IPSec. I have the client
installed on an NT machine.
Does anyone know how to configure the firewall to allow this traffic? Is
this possible? Or is there an IPSec patch that needs to be applied?
Thanks, any help would be appreciated.

Greetings,
I have a Win 95 system with a 3Com 3C900B-TPO NIC, and I would like to
convert the system over to use Linux. The Linux Ethernet-Howto doesn't
list this card as supported. Before I waste a lot of time trying to
get this card to work, I was wondering if anyone had any experience
with it and could at least tell me what driver to use?
Thanks,

Here in comp.os.linux.networking, [EMAIL PROTECTED] (j)
spake unto us, saying:
The sheer number of messages posted here - usually half going
unanswered - tells the tale ... Linux networking sucks.
Other conclusions can be drawn, like
"Linux networking is more flexible so there are more things to ask
questions about",
or
"Linux networking is different from what new users are used to, and
the Linux community encourages asking questions on Usenet"
Now you can take your Winders, add in file-sharing in just a
couple of minutes, bring up your Winders workstations and
locate and link in within just another few minutes. Easy.
Quick. Relatively painless. Not the Linux way ...
Then why can't Windows 95 OSR2 see my Intel EtherExpress Pro/100B NIC
at all when OS/2 Warp 4, Solaris 2.6, FreeBSD 2.2.7, and various Linux
flavors seem to see it fine?
Perhaps it's painless because it doesn't work. :-)
Now you may try to defend Linux by saying that it has more
"flexibility" - but quite frankly we could do with a lot
less "flexibility" and a lot more simplicity.
I disagree, and I'd like to request that you stop speaking for me...
Now you thought I was just gonna flame ... nope. I've been
relatively polite and realistic here. There are MANY issues
to address, MANY refinements to be made before Linux becomes
a really good option for administrators of small/medium networks.
Yes, if you want to have such networks set up by people without UNIX
networking knowledge. Whether that's a wise idea or not is up to the
entity supplying the boxes and depending on the network, of cource.

That's actually a common idea. Not pink grin, but color-coding the

I color-code my prompts here by system, and when I log in as root I
use red text with the system name in the center in the system's normal

The way to do it is to use ANSI escape sequences. The ones I use on

Root prompt (set in /root/.bashrc):

they still don't use the standard UART interface that real modems use. Not

Hi!
I've to test the performance in a LAN with let's say 100 workstations.
So the question is: How can I test this - are there any tools available?
The tool should tell me about:
min/average/max transferred KB/S
min/average/max time until a response arrives
...
Of course it would be really nice if the tool could simulate 10/25/50
"typical" users...
Yeah, I know the description above isn't real concrete but please make

Oh, really?
I am a Windoze developer by profession. I run Linux at home and for
everything else I do. When I joined the Linux community, I didn't have a
clue about Linux (or Unix in general) except for the limited work I did in
college. I'm still relatively clueless (but getting more knowledgable
everyday). Here's what this clueless person has done with Linux:
1) Developed client/server applications using Borland Delphi C/S and
Interbase for Linux. The resulting application (i.e the Interbase server)
runs 24x7 with 24x7 availability for the clients. This was my first
project.
2) Developing a PERL module to access Interbase directly.
3) Wrote PPP scripts that allowed me to connect to my multiple ISPs.
4) Set my server to as a PPP dialin server. I can now call my machine at
home securely and work on my machine.
5) Reconfigured my dialin server so that I can dialin to my PC AND surf the
internet at the same time.
6) Learning about setting up networks (I have a 3 PC network).
7) Setup and operate and FTP and HTTP server.
8) Share my files on my server with my Windoze clients using SAMBA.
Yeah...Linux networking sucks.
It would be nice if some of the tools were a bit easier to use. But, they
work. Usability will

Rec---Xmit
There cannot be a collision. One computer the Xmit is connected directly to the
Rec and the Rec is connected directly to the Xmit.
With a Hub, all the Xmit's are connected on the same side, and all the Rec's are
connected on the same side. It's up to the Hub to allow only one Xmit or Rec at
a time between one set of computers. If two sets of computers try to communicate
to the same computer at the same time, there is a possibility of a collision.

"A hub takes any incoming signal and repeats it out all ports."
That is, a hub is just a multi-port repeater.
It makes _NO_ decisions about the communication going on between
machines.

No, a hub is designed to to take packets and distribute them as best as

Perhaps I am wrong, but I thought a hub simply made the appropriate
electrical connections. That is, to my knowledge, a hub does not
deal with packets, only with electronics. (If it deals with packets
and distributes them to their destinations appropriately, then it
is probably a switch. Granted, one could say "hub" and mean
"switching hub", but in those context (microhubs) that's probably
not the idea.)
So, in my understanding, you're *just* as likely to have packets
collide on a two host network whether or not you have a hub.

Well, I'm having a problem getting DHCP to work. I have Red Hat 5.2 and I've
read both HOWTO's on dhcpcd and cablemodems. I've gone as far as rewriting the
scripts and still nothing works...if I set the modem as a static IP (which I'm
really stealing use of an IP) it works just fine. And I can get dhcpcd to work
if I manually set -h switch to my host name.
If any one has any answers than send me an e-mail.
Thanks

Hmm,
Did it ever occur to you, that the reason it seems so hard is that you
probably don't know what you're doing? Linux just has a higher learning
curve -- but it pays.
I'm not flaming you, because I'm in exactly the same situation, but consider
the _fact_ that as soon as you have a good working understanding of what
you're doing, everything becomes so simple, you wonder how you ever went
wrong...
But unlike Windoze, you'll actually know how it works, not just how to get
it working on only one machine. In one month of use, it still doesn't work
perfectly, but my knowledge has at least doubled, just by using something
non-MS.
Then again, we have to wonder what you're doing on this board in the first
place.
If you don't like Linux, fix it or drop it.
Power, flexibility, extensibility, and _stability_
That would be "The Linux Way", as you (didn't) put it

Is it possible to have a DNS server forward a request to another
server? Specifically, I want the primary DNS server for my company to
forward unresolved requests for our local domain to the DHCP server
which will also be running named. This way I can keep the database on
the DHCP server up to date but update the primary server at longer
intervals -- maybe once per day. From RTing the FM this _looks_
possible (using the forwarding directive?) but my experience with DNS
is too limited for me to commit to it.
AFAIK this is not possible using standard BIND. BIND does not forward
requests for domains for which it considers itself authoratative.
You can, of course, put the DHCP allocated names in a subdomain and
deligate it.
Alternatively use a DNS server that supports dynamic updates and send
it dynamic updates. Eventually dhcpd will be able to do this
automatically.

Well, I found the cause myself!
For anyone who's interested...
I swapped the 10Mbps and 100Mbps PCI network cards.
Somehow the port or interrupt assignment has something to do with it.
If anyone knows the real reason I appreciate a message.
