Did you configure /etc/syslog.conf, create /var/log/ppp-log, and then do
killall -1 syslogd
( or killall -HUP syslogd or kill -HUP `pidof syslogd` )
to force syslogd to read /etc/syslog.conf ?
Is syslogd running? My "older" syslogd is picky about TAB separators in
syslog.conf, and spaces cause it to die when it reads the file.
You really need the chat -v and pppd link negotiation debug log messages
to help determine what happened. The messages in your post just aren't
enough.

This smells more and more like a cabling issue, if you are sure about the
address assignment. The result of the tcpdump indicates that you are only
ever seeing ARP requests, and never an ARP reply. This exchange is
necessary before you will ever get any traffic between two machines.
Are all the little lights on the interface cards at BOTH ends showing that
the card thinks the link is good? Is there some other confusion (at .52)
about which interface is assigned which address?
And how does the ppp0 interface fit into all of this (on .51)?

Date: Sun, 06 Jun 1999 20:10:33 -0500
hey folks,
i am fairly new to linux and i need some help please.
i am trying to set up a home network. i have a linux machine running
redhat 6.0. i also have another linux machine running redhat and
another running nt. i have all the machines hooked up on an ethernet.
i've read a bit about ipchains. i have to admit i didn't grasp it too
well.
i would like to use my dial up ppp connection on my first linux box to
allow internet connections to all the other boxes.
i use the reserved ip addresses for a class c network.
my linux box is 192.168.0.1
my nt box is 192.168.0.2
my other linux box is 192.168.0.3
what is the easiest way to set this up using ipchains.
do i need other items compiled into the kernel or is 6.0 ready to go as
is?
thanks in advance for the help.

I think the two are equivalent. What port forwarding does is to create a
hole
in the firewall for a given port. This seems about the same as allowing
access
to a given port on the firewall machine. It seems to me that a pretty good
arrangement would be to have the web-server on the firewall machine, and
the database back-end on an internal machine. You could then explicitly
permit access between the web server and the backend, and nothing else
from outside.
> Is there a downside to doing this ?
The downside to port-forwarding is that you then have to watch 2 machines
like a hawk instead of just one.

Subject: LINUX/win98 network via IPX !?!?!?!?
Date: Mon, 07 Jun 1999 00:57:58 GMT
I have a linux machine tied to a hub at 100baseTX, as well as a win98
machine. hub uplinks to a cable modem. cable modem assigns IP numbers to
both boxes via DHCP. works beautifully.
the only problem is, the two boxes are assigned IPs of different subnets.
so I'm trying to configure the network to go via IPX instead.
gotten it to work in network neighborhood with two win98 machines, but how
do I get linux to work with win98 via IPX ???
I understand TCP/IP pretty well, but IPX is new to me, so be kind. =-0

Subject: Speed problems through IP Masq.
Date: Tue, 1 Jun 1999 22:11:42 +1000
I have a linux box running as an internet gateway (IP Masquerading and
Squid), and a file server (Samba). The computer uses a dial up ppp link to
the isp. The ipchains rules are pretty simple:
Chain forward (policy DENY):
MASQ all ------ localnet/8 anywhere n/a
This just masquerades everything (that is destined for the internet) from
the local network out onto the internet.
However this does not run at anything close to a reasonable speed. ie I can
normally download from the web at up to 5 k but normally closer to 3k. but
through the server with no other load on the link I am getting 200 - 800
bytes per second... As well an FTP mirror which I can also normally get
access to quite quickly has the same problem.
I originally set up the squid server to try to reduce the load on the
connection a little as the computers that use the link start at the same
homepage and may very well follow simular links. However this connection is
slower again with speeds between 80 and 400 bytes per second.
Firstly, is there any tweaking I can do to improve this?
Secondly, how CPU and RAM intensive is this process of proxying and
masquerading?
Thanks

I understand the Netgear FA310TX revision C* uses
the DEC 21140 chipset. How do you identify one of
these? My local CompUSA has about a dozen Netgear
cards on the shelf three of which have a "C" at
the end of the stenciling on the largest chip.
Can someone who has one of the cards using the DEC
chip post some information on how to identify this
card?

Thanks for the link and I'll try to recompile the kernel.

I did read those HOWTO's and the network settings were correct, was able to
ping the loopback and the assigned IP address. Off to find some kernel

To find out what's waking diald up, try hanging a tcpdump on the
proxy interface (usually sl0).

Not quite as such. It's easier to configure it to ignore stuff which
you _don't_ want to wake the link up (like NTP) than only to bring it
up for what you may want (e.g. HTTP which would ignore NNTP).
> It seems to be a little TOO sensitive.
It's all configurable. Have a look at /etc/diald.conf and, of course,
the man pages, for all the subtle details.
Hints: configure it to ignore NetBT (NetBIOS over IP - a M$ problem)
and NTP packets (if you run NTP on your LAN). Those bits are guaranteed
to bring up a link every few minutes.
Good luck!

Hey Matt,
I'm no expert but I believe if you remove the word "anonymous" out of
the line "class real,guest,anonymous" in the file /etc/ftpaccess that'll
do it.

Subject: Warning against Announce Communications web hosting
Date: Tue, 01 Jun 1999 14:26:07 +0200
Since Allen Hoffman of Announce Communications has announced his web
hosting business here I feel it is appropriate to warn you about my bad
experiences with this business.
The business is cheap, but service is extremely poor. Severe errors are
only fixed after many complaints, and less severe errors are never fixed
at all. Most E-mails are never answered. But worst of all: if you are
dissatisfied and want to move to another service provider, you may not
be able to transfer your domain name.
My story is:
I have bought a domain web site at Announce Communications. In april my
site went down because mr Hoffman failed to pay the Internic bill. All
my complaints remained unanswered. After a month I decided that I had to
move my domain to another ISP. Only after he learned that I was moving
the domain did I hear from mr Hoffman. Do you think it was an apology?
Or an offer to refund what I had paid for a faulty service? No - you
can't guess it. It was a demand that I pay him 70$ for releasing my
domain! My question is now: is it possible to move the domain without
his permission? The internic record has my name as registrant, and his
name as administrative contact.

That's the 'multi device' support kernel thread, which is the linux name
for raid. Your kernel was compiled with raid support, and so it starts
those threads on boot. The only way I know of to make them go away is
to remove raid support from the kernel.

I have moved the network card I got from them into three seperate computers no
problem can conect with any of them.
If I use any of these computers with another nic it fails to connect I know the
cards work because the machines show up on my
network. It is the only thing I can think of. If you are using mediaone just get
the numbers for them from a windows box they say you have a dynamic IP but i've
been using the same ip address for almost a year with no problems.

Hello,
I have a small network (2 PC's) on PC is a Linux box running RH6 and
the other box is Window98. Now the Linux box has IP Masquerading setup
and I use it to connect to the internet. I can now use the Win98 box
(via the Linux box's internet connection) to browse the internet.
Here's the problem:
If I use the Linux box to browse the internet, I can't. I make sure I
have an internet connection but nothing works. Keep in mind that the
Win98 box, while in this scenario, works just fine. I want two users to
be on the internet at the same time, but it's become impossible with
this setup, please help.

Hi,
I have just installed Mandrak Linux 6.0 on this computer, I had been
using Red Hat... and it worked fine for the internet... but was kind of
broken for some things...
But I have problems with the internet in Mandrake now. I can connect to
some sites with no problems, but others I get no route to host. Some
sites that I have pinged I don't get packets returned.
I think it is a problem with routing, but in linuxconf, it is set to set
up default route when connecting with PPP.
Has anyone had a simular problem and been able to fix it thanks,
