Subject: router/LAN switch?
Date: Mon, 08 Feb 1999 17:24:54 -0800
Hello everyone,
I have a question regarding LAN switches/Routers. This is the
situation/problem:
I'm working for an ISP that distributes internet though
cable modems.
In the early stage of this project we had 3 channels
(each operated within different frequenties) and only one of
them had Internet access (we used the other two to connect
companies with several buildings). Now we want to provide
access to more channels (perhaps even 5-8 channels).
But here's where're the problem comes in: We currently
use a gateway (a pc running Linux) that's just plugged into
a cable modem and everything's fine. But if we want to
serve more channels it's impossible to keep inserting
ethernet cards into the gateway. So we figured we needed
some router/LAN switch.
Here's a more detailed situation description:
Current situation:
Network I-net
Management |
Station gateway
| |
ch 1/2/3modem modem
------------------
New situation:
Network I-net
Management |
Station gateway
| |
----------------------
new router/LAN switch?
----------------------
| | | | |
| | ch 3 | |
| ch 2 ch 4 |
ch 1 ch 5
ch 1 = Channel 1 (psysically just a modem set to that frequency)
This are the requirements:
1. The various channels may not communicate with each other directly
through
the router/LAN.
2. The various channels may only communicate with the gateway. Some
channels
will not have I-net access for security reasons and may not pass
through
router/LAN switch at all. The only reason they are connected is
because of
the third requirement.
3. The Network Management Station must be able to reach all hosts on all
channels.
furthermore the channels are 515 Kbs / 4 Mbs so 10 Mbs line speeds would
probably suffice. Also we use ip masquerading at the gateway, so we can
determine our own ip numbers inside. All the channels are in the same ip
subnet. (so that we can switch modems/pc from one channel to another
easily)
I have looked at some cisco products, especially at the Catalyst 1900
switch and the Cisco 4000-M router. But I wasn't able to determine if
the
Catalyst (or any switch for that matter) can be configured like we want
to.
We would prefer a LAN switch over a router for obvious reason of not
having
to split our ip-adresses into more subnets.
Does somebody have any experience with this sort of problems?
any advice would be greatly appreciated?

There's definitely something not quite right about the 2.2.1 kernel. I have
an NE2000 clone that isn't getting its IRQ detected. This works fine under
2.0.35, BTW. I've also had a 1542B lockup under 2.2.1 to the point that I had
to power down the computer before either 2.0.35 or 2.2.1 would recognize it
again. I think that's the first the computer has been powered down in months.
On the plus side, performance is definitely up under 2.2.1, presumably because
of the improved SMP.
During boot, I see a message about the NE2000 that shows the correct I/O
address (0x280), but says it cannot detect the IRQ. If I feed it the IRQ (15)
through boot parameters, the boot message shows the correct I/O address and
IRQ, /proc/interrupt shows the card correctly, but it still doesn't work. If
I try to ping another machine on the LAN, I see a TX timeout interrupt message
in /proc/kmsg. So something's mucked up. If I boot 2.0.35 or Windoze 98,
everything works fine. And yes, I'm sure I have the correct I/O and IRQ.
Someone else mentioned that loading the NE2000 driver as a module works. I
may try that, but other problems I'm seeing with the 1542 and devices connected
to it may keep me from using 2.2.1.
The machine in question is a dual Pentium Pro 200/512K, Supermicro P6DNF
motherboard, 16 port Digiboard, Adaptec 2940UW (internal HD, CD-ROMs, and
streaming tape), Adaptec 1542B (external DAT tape and scanner), Accton NE2000
clone, SB AWE64, and Millenium G200 PCI.

For the most part I have beem successful at upgrading to 2.2.1. About

comes up fine. If I try to use the "new msg", "reply" or "forward"
buttons, netscape hangs and I have to kill netscape. Soooo, Inorder to
send a message, I have to reboot the system and come up in my old 2.0.36

Can anyone point me to a fix???

Hi all,
I was wondering if this is documented or if someone has seen this problem
before? I am mounting a volume from a NetApp box to my linux server and
writing logs across the network. After a little while (200-300MB) of
writing, I get bad filehandle errors and failed revalidation of inode
messages. The log files are actually not visable at this point from any
machine also mounting this volume, but become visable after the processes
that are writing them get HUP'd or KILL'd. Is there an issue with open for
write nfs file sizes? Anyone have anything they could offer? Many thanks.

Hi Martin,
I just set up a home network myself, using a Linux box as a server for IP
masquerading to allow internet access to the other Windows machines on the
network, run Apache (a WWW server), and to funtion as an Oracle development
platform. I bought a book titled 'Using Linux, Special Edition" at Barnes &
Noble. It came with both the Red Hat and Caldera distributions, and has good
entry-level information on setting up and using Linux (tells you how to use
vi, too). I found the Red Hat distribution to be quite painless to install.
Have fun.

Yes, and it seems to work. I thought internal zones would fail, because the server
would forward before looking on the local server, taking "forward only" literally.
Using forward only with local zones does work.
It seems that bind checks first to see if it has the zone and returns the answer. Then
if it doesn't know it forwards the call. "forward only" works behind a firewall, but
"forward first" needs to know what the root servers are. My hacked named.ca worked,
but
forward only works better.
Thanks.

I don't know about Debian but I couldn't get Redhat 5.2 with kernel 2.2.1
and the updated client to work. OTOH the older kernel and client worked
fine. I'm currently running SuSE 6.0 and kernel 2.2.1. Works fine. With
RedHat and 2.2.1 it kept timing out. Did you try RedHat with the older kernel?

Greetings!
I've successfully gotten kde's kppp to dial in and connect to my isp. I'm
using a 33.6 modem (speed set to 57600) on IRQ 3 (at boot up it sets it to
4 but I never got connect on IRQ 4).
The problem is the whole thing is running agonizingly slow. Most of the
time I get LCP time out and if I do connect Netscape runs at 10-20 bytes
per second.
I think the problem is my IRQ setting what is the best way to determine
which IRQ a modem should be set to? And once figured out how do you
permanently set a modem to that IRQ? Setserial doesn't seem to stick on a
reboot.
Thanks kindly!

Hmmm. We didn't need these options before, and in fact, if I go back to
my 2.0.36/dhcpcd-0.70 setup, DHCP works without them. I think perhaps I
need to investigate some of the changes that were made to IPV4 networking
between 2.0.36 and 2.2.x.

Let's see if I understand correctly. You reboot the linux box and are
able to ping the windoze box. Then, after a short period of time, you are
no longer able to ping the windoze box.
Possibility: After you reboot, you set up your interfaces the way you
want them. But, your ISP sets your IP via DHCP (presupposes that you have
dhcpcd or dhclient running) and the routing table gets changed. All of a
sudden, things don't work right anymore.
Hope this helps,

This is not a good idea since all packets will be put on the wires even
if you have the firewall in place! Since they share the same interface,
for both networks, then both networks share the same data as well, not
good! Go spend $50 for another card and do it the right way: two cards,
two physical networks. All packets MUST go through the box this way and
you have control over what you want to go through.

Date: Mon, 08 Feb 1999 16:05:55 -0500
Hi All-
I thought I'd post this FYI. I subscribed to Bell Atlantic's ADSL
service but chose cais as my internet service provider. The main
reason I chose cais was that the salesman said connecting with linux
is not problem. Technically, I guess he was right. The ADSL connection
works fine ... but all cais adsl accounts are assigned reserved
ip number's behind their firewall. I called technical support
to inquire about obtaining a "non-firewalled" ip number ..... mainly
so I could telnet, ftp, ssh or sftp into my adsl account from the
outside.
Here was there answer.
>There is no way to get a "real ip" from Cais. All of our adsl accounts are
>behind our firewall.
Needless to say, I was very disappointed. I do not think cais is
interested in changing
their policy. It is possible that most of their customers are just
interested in surfing the web and do not need to be able to connect
from the outside.
Anyways, I thought I'd get the word out. Changing ISP's for an
ADSL account is turning out to be a pain in the rear.
Joe Lingevitch
PS. Technical support from Bell Atlantic says that they do
assign "real" ip numbers to their adsl customers. They will be
migrating to a dynamic ip number assignment soon but I was told
that the pool of ip numbers will still be outward looking.

Date: 8 Feb 1999 14:38:07 GMT
Hello !!
My network topology is showed as below:
router -> Internet
|
|

| 203.73.156.62
|
+---+-> 203.73.156.0/255.255.255.192
|
|eth0 203.73.156.1
Host_A : 192.168.0.1/30 ppp0 <-> ppp0 Host_B : 192.168.0.2/30

/(Group A) \(Group B)
/ \
192.168.1.0/24 192.168.2.0/24
(master: NTSVR1) (No master)
I have some problems, could someone kind give me a hand !! Thanx !!
1. All the Host_A and Host_B is linux box with RH 5.1.
The two box is connected by modem over a 9600 bps lease line.
The default gateway of Host_A is 203.73.156.62(eth0),
and the default gateway of Host_B is 192.168.0.1(ppp0).
Each box also connects to another subnet, but only Host_A run
IP-Masquerade
with IP-Forwarding set as ipfwadm -F -a m -S 192.168.0.0/16 -D 0/0
Host_A is also the mail & DNS server
2. about PPP
I run PPP daemon by inittab with respawn action, so that when the
connection broken
it will re-connect. (the quality of lease line is so bad)
BUT I wish Host_B to use the same network 203.73.156.0 with IP
203.73.156.2 and
don't masquerade. How to do it?
3. about routing
I wish the member of Group_A/B can watch each other by Samba. But when I
traceroute,
the Host_A always search from eth0. The routing table of each Host
doesn't add the
network and gateway (ppp0) of the other.
So, I run gated daemon with rip protocol and static setting. when daemon
starts,
the routing table is really what I wish, but after a few minutes the
daemon disappears.
I exam /var/run/gated.pid the process doesn't running but file exist?
Why ??
So, when the PPP reconnect, the routing table won't re-add the routing
path.
I exam the /var/log/messages file. I only find the action of pppd.
What happen about gated daemon. Should I run it? or I just add the
routing by the route
command when ppp establish. how to add it to the ppp script
The line in inittab about PPP:
a1:12345:respawn:/etc/ppp/ppp-connect >/dev/null 2>/dev/null
the file of /etc/ppp/ppp-connect:
exec /usr/sbin/pppd connect 'chat -v "" "AT&L1M0A" "CONNECT" '

4. about mail:
At the beginning, the mails are all send from Host_A and return-path is
masquerading
as Host_A.
In order to lite the space of Host_A and let the members of Group_B to
fetch mail
quickly, I relay the mail of members of Group_B to Host_B by editing
/etc/aliases.
So that the members of Group_B can fetch their mail from Host_B by POP3.
I wish they can also send mail from Host_B and return-path is
masquerading as
"Host_A". So, I edit the same part of sendmail.cf of Host_B. However, it
does'n work !!
How to do it ??!!
5. about Samba:
As I script at point 3. I wish the member of Group_A/B can watch each
other and
share the resource by samba. (Most is M$-Wxx) I edit /etc/smb.conf of
Host_B
with adding below:
remote announce = 192.168.1.255/Group_A
remote browse sync = 192.168.1.255
domain master = yes
local master = no
interfaces = 192.168.0.2/255.255.255.252
but the member of Group_A can't watch it.
How to do it ?!
Thank you for reading my problem !!

I doubt that the file descriptors are the culprit. The default
setting (as defined in /usr/include/linux/posix_types.h) is 1024 .
You'll probably have to edit fs.h and limits.h ; me thinks that
NR_OPEN has to be changed .
