The correct solution is, as stated, to plug the DSL into a hub, and run
anything with a real IP off that hub. AFAIK, that purpose isn't really
routing, and the only way it saves you money is if you get a network
card
cheaper than a hub (easy enough) and if your time isn't worth money.
It'll
take you quite some time of fiddling with it, and you won't have as good
of a setup.
Personally, I have a boatload of NICs, and was going to make my
intranet by using a lot of cards and save the money on the hub, but
for the $35 I spent for a 5 port hub, I saved a whole lot of time
and frustration.
On http://www.pricewatch.com you'll find a couple links to places
you can get a 8 port hub for $28 plus shipping... Isn't 4 to 20 hours
of your time worth $28? A hub works right away - you plug it in, it
goes. No fooling with configurations and routing tables, multiple
ethernet cards in each machine, crossover cables, recompiling
kernels, etc...

Subject: Does Linux 2.2.2+GRE and Cisco Tunnel actually work?
Date: Fri, 5 Mar 1999 17:17:13 -0500
Hello!
I am trying to tunnel, using GRE, between a Linux 2.2.2 box and a Cisco
router. I have successfully been able to tunnel, using GRE, between two
Linux boxes. I can't get the Linux->Cisco tunneling working.
I have numerous command examples. I'm wondering if anyone has actually got
this to work. I think I'm not doing something right on my Cisco box. Any
hints or ideas for special configurations for Cisco IOS?
Thanks very much,

You won't need the 100. You also won't need any more RAM, if the
computer
will be dedicated as a server.. like if it's just providing internet
access to the other 20, and serving a web page to the outside world.
Use the money that they budgeted for RAM to get a really nice monitor
or something..:) Cheap ISA 10mbit cards work best...

The less Plug n Play it is, the better. Old NE2000 cards with jumpers
for their IO and IRQ are best, IMHO. They always work best for me.

Most cable modems use ethernet cards for a standard TCP/IP connection.
Those are all supported...just have a network card installed.
I'm curious. What kind of card do you have in it that doesn't work?
You may just need to configure it.

You should do the first. If you set it up to remote execute Netscape,
it will never suffice, no matter how much RAM you put in - netscape is
bloated and one netscape running will hog that 486dx66, let alone 5 or
20.
Check out http://ipmasq.cjb.net for information on IP Masquerading,
which is probably what you should do. If you only want to allow web
browsing and nothing else, than a proxy server (search for Squid and
Apache) will do nicely, and could speed things up.

Date: Fri, 05 Mar 1999 23:08:11 GMT
Hi Dave,
The reason you can't use the internet after issuing "ifconfig eth1 up"
because the "route(s)" using that interface were deleted when you issued
"ifconfig eth1 down". You need to reinstate those route(s):
route add default eth1 # Will create the default route to the internet.
Note that your default route should be to the Internet because the route
to your local network is known (probably: "route add -net 192.168.1.0
eth0"?).

Well, you could also download a NT NFS server and you can use NFS to
connect to the NT server.
Or you could install IIS with ftp and you can ftp your way into the NT

But my opinion is that Samba is the best out of these.

I'm having problems getting my 486/DX4 100 running RH5.2 to detect my NDC
Communications Sohoware PNP Ethernet Adapter which is NE2000 Compatible. It
flat out will not detect or use the card for some reason. The manufacturers

I've tried using the driver disk to get to the SCO driver but RH5.2 will not
find any files/directories on the disc. I am a new Linux user (yes, another
newbie) and may be asking something that has been asked time and time again.
If this is the case I'm sorry for the repeat. I would appreciate any help

Subject: Shapecfg + QoS
Date: Fri, 5 Mar 1999 17:05:56 -0000
Hi,
I'm currentlly running i386 2.2.1 and I want to try out some features of
the newer versions. The lab is something like this:
I have this linux acting as a router between network 192.168.1.0/24 and
192.168.5.0/24. I want to be a able to:
1 - Use shapecfg to create a 33600 line (for example). All traffic flowing
from network 5 to network 1 should go through this device.
2 - Creating another device (shaper1) inside this one with 9600 bps. This
device should be used to pass ftp data. Doing this, I want to say: "FTP is
limited to 9600bps PERIOD.".
3 - Give priority to telnet over any other traffic but only limit it to
shaper0 - shaper1 bandwith (maybe creating another shaper). Give http
traffic the second priority and telling him that it could use the full
bandwith.
So, the result would be:
- If I start a FTP I would get 9K max. After that I start a HTTP download
and I can get full bandwith (33K). But if I run after that, I could have at
least a minimum input/output.
Something like this:
----------------------------------------------------------
---------------------------------------------------------
|
------------------------------------
| | |
| shaper0 shaper1
eth0
--------------------------------------
| |
---------------------------------------------------------
|
----------------------------------------------------------
and see ftp traffic only flowing on shaper1, telnet traffic on shaper0 -
(MINUS) shaper1 and http traffic all over :)
Now the tests...
I think I can play with the Tos field and ipchains to priorityze traffic.
I've not tried it yep, cause I was trying to create a shaper device, but my
computer just locks up !!!
I do something like what is writed in the
Documentation/Networking/shaper.txt
1 - shapecfg attach shaper0 eth0
2 - shapecfg speed shaper0 33600
3 - ifconfig shaper0 192.168.1.175 netmask 255.255.255.0 broadcast
192.168.1.255 up
4 - route add -net 192.168.1.0 netmask 255.255.255.0 dev shaper0
5 - ipchains -A output -s 192.168.1.0/24 -d 192.168.1.0/24 -j ACCEPT -i
shaper0
My Linux router is 192.168.1.175 as you could see above. Then I grab a PC
from network 5 and just type: ping 192.168.1.1 , and 192.168.1.175 just
dies. Have to reset !
Am I asking too much ? Or is that possible to do everything I said?
What am I doing wrong with shapecfg ?
Any help will be apreciated.
Thanx in advance,

The Masquerading HOWTO suggests adding the -W option to the line shown
above of your firewalling code. I found that if one is using ppp0 to
dial out on, then the option to add is:
-W ppp0
I'm not really sure what security this adds, and if anybody could expand
upon the brief words in the man page, that would be helpful.

Best way is to make sure your Linux box is tight. Edit /etc/inetd.conf
and comment out all services. Shutdown all other network services you
are not using, eg. web servers, nntp servers, mail servers, etc.
Install qmail if you wish to ensure some level of security and you must
run a mail server.

I used to have a Motorola BitSurfr external ISDN modem, where I got this feature
to work.
The feature you need is called multi-link PPP.
First, your ISP must support it. Most of them do, but they charge more for it.
Second, the modem must have a setting to switch to ML-PPP. My BitSurfr had. Look
in your modem docs to find out about that.
You then send the string to switch the modem to ML-PPP as part of the modem init
string.

this is easy to fix...
add this to your /etc/modules (or modprobe in rc.d files)
ne io=0x(io address of card 1) irq=(irq of card 1)
ne io=0x(io address of card 2) irq=(irq of card 2)
you could put more card till you run out of addresses.. :)
you will need to ifconfig the second card to whatever address and netmask
and add the route but thats another story...
Hope that helps

I as yet have not had the pleasure of checking out the performance of an SGI
under heavy network load. As for Suns, I used to say they were good for two
things: when you needed a machine that you could shoot with a high-powered
rifle and would still keep going, and for running a database. With the
advent of Oracle Linux, Sun boxes are that much less useful in my eyes. Of
course, there are still a large number of companies that need uber-reliable
machines on which to run their operations, and who have no qualms about
sacrificing speed for stability. I've simply never worked for any of those
companies.

See, this is a completely different type of problem than those I'm used to
dealing with. My typical design considerations all involve pushing a machine
to its absolute limit, because the individual machines are almost always part
of a cluster (and the design objective is usually to minimize the number of
machines, i.e. maximize the output per machine). Under low load ("low" being
a relative term, of course), I definitely think Linux outperforms pretty much
everything else out there. It's the *extreme* cases that interest me (and
quite a few other people, actually). In one configuration I've tested, a
P266 with 256M of ram running FreeBSD acted as a NFS client and Web server,
passing over 14 megabits per second in data for public http requests
(sustained for over eight hours per day, dropping down to around 10 megabits
per second at off-peak). A similarly configured Linux box we tried to put
into the same environment (and which had actually tested better than the
FreeBSD boxes at lower loads) simply died (memory available for buffering
network i/o was exhausted in a matter of minutes, and if my own memory serves
correctly, this resulted in some sort of kernel panic).
