You would see exactly that. The user authorisation will then be done via
PAP (probably) or CHAP. Your username and password then go inot the
/etc/ppp/pap-secrets or /etc/ppp/chap-secrets file.
So, have the chat script finish after it sees the CONNECT message, and
let pppd take over. Look in /var/log/messages for a
<auth pap> or <auth chap> in one of the lines. That will tell you
which.

Why switch what device eth0 and eth1 is attached to? Perhaps I'm missing
something, but it would seem that if you're just insisting on using certain
addresses for certain traffic you could use ifconfig and the route command to
swap the addresses.

Hello all,
i have a SuSE Linux 6.0 box "running" as a router.
2 Nics are installed. Every NIC on a different subnet.
Here�s my problem:
i can ping every NICs IP Adress from both subnets. But i CANT ping
Clients residing in the different subnet. It seems that there is no IP
forwarding enabled. I checked the Kernel with make menuconfig, but it tells
me that ip forwarding has been enabled and installed.

Try setting up your machines on a private network (192.168.[1-254].x).
IIRC, you need to do this with IP masquerading (the whole point is to hide
an entire network behind a single IP address).

I am in routing hell, and I don't know why.
Got my ADSL link a few days ago, and (to appease the BellAtlantic
geniuses) had them set it up via W95. Everything worked ok, so
the first troubleshooting issue is solved: the link physically
works.
Now, drop out the W95 box for the Linux box. Go to set up the
routing, and here's where it looks like Bell is lying to me:
IP: 151.200.17.173 (fine)
Gateway: 151.200.16.1 (hmm.. same subnet still?)
Subnet mask: 255.255.255.0 (what??? how can this be?)
Because of Win95's braindead TCP/IP, this works somehow despite
the fact that the subnet mask should conceivably make the gateway
"invisible". But it works.
Linux won't let me define this gateway with this subnet mask
(assuming a broadcast of 151.200.17.255). Attempts to try to
guess the "real" subnet mask and broadcast don't work either--
I figured, with 16 and 17 in the subnet, that it would be safe
to define:
Subnet mask: 255.255.224.0
Broadcast: 151.200.31.255
I can add the given default gateway route now, but nothing actually
gets routed. It's like I'm completely cut off. I can ping myself.
That's it.
Given the info above, does anyone have any idea how to get this
machine alive on the network?
Frustratedly yours,
Joe

Reply-To: [EMAIL PROTECTED]
Hi all:
I'm a relative Newbie, having only installed Linux (SuSE 5.3) in the
past month. I'm starting to get comfortable with it now, and would like
to start experimenting with networking. The problem is, I have all kinds
of old, weird hardware, and need some advice on which would be the best
way to approach it.
I have Linux running on 2 machines now: a Pentium 133 w/16 MB of RAM,
and a 486/33 with 20 MB. I also have a Toshiba 486/75 laptop (8 MB) and
could cobble together a 386 (up to 8 MB, maybe) out of spare parts. I'd
rather not start messing with the Pentium (my main box, and if I screw
it up, I'm up a creek) until I have a pretty good idea of what I'm
doing. I also have 3 ISA Ethernet cards (2 Etherlink III and one
Etherlink II) I could install.
I'd be most comfortable setting the 486 up as the server and linking one
of the other boxes to it as a client. I have about a GB of disk space to
play with there, and considerably less on the other 2.
Problem #1: Installation. The Toshiba has a really off-brand PCMCIA 2x
CD-ROM. I bought it overseas and can't even find Win95 drivers for it.
The company that made it (TXC) has no web presence as far as I've been
able to determine. The DOS drivers are made by Oak Technologies and when
I wrote them, they said to contact the OEM. The 386 wouldn't have any
CD-ROM at all, and at best two 40 MB HD's.
Am I better off trying to get the CD-ROM working on the Toshiba, or
installing a minimal Linux from floppies on either box and then doing
the rest over a network connection? I could be willing to spring for a
PCMCIA NIC for the Toshiba, but don't want to spend any more until I
know what I'm doing (and what I want to do in the near future).
I also have a SyQuest EZflyer 230 MB parallel port drive. I could try to
do an installation off that too, but they filed Chap. 11 in Nov. so
tech. support there isn't going to be too easy to come by. I haven't
even tried to get it mounted on either of the working boxes yet.
This is getting a little long, so I'll hold other problems for a future
post.
An e-mail repy would be appreciated as I don't get onto the newsgroups
as often as I'd like.

If you are using RedHat you have to install imap rpm

I'm pretty sure that I've got me a crappy phone line. I've had the same ISP and
modem for years, but I just got the noisy phone line recently.
But what's interesting is...I wasn't having as much trouble since I've "upgraded"
to Redhat 5.1. I actually did a re-install, from scratch on a new hard drive. I
have my old drive backed up, so I could pull any old config files off of the
backup. I just don't know what to look for.
I'm wodering if there are any settings that can be adjusted that make the ppp
connection more robust for noisy lines, such as error checking parity or
something.

Subject: Newbie Q: Linux Box as Router, Server, Gateway?
Date: 30 Jan 1999 06:34:13 GMT
Hi,
I have tried to lurk to find the answer, but here goes:
I want(hope??) to build a Linux Box for a home network connected to the net by
Cable Modem with IP masquerading with a possiblity of web hosting.
I intend to have a number of WinNT/9X PCs connected by Samba to the Linux Box which
has the
cable modem connected to it. I know Samba does the file/print sharing for
Linux/Windows.
The Win PCs will have NICs, but do I need a hub to connect to a NIC on the LInux Box?
Or can I add more NICs to the LInux BOX to become a router, with direct wire
connections
from the other NICs. Can (and intend to) use 10/100 NICs all around, hoping for 100.
And if the above is possible, obviously I am limited by the # of NICs I can put in a
Linux
box, can I then add a small 4 port hub with one port to the Linux Server.
Yes, it sounds like a lot of work just to eliminate one piece of hardware, but with a
small
home network and access to cheap NICs, this seems like a legit question to me.
If the above is possible, what software components do I need, I know I will need the
following:
Recent Linux Distribution with all Relevant Hardware Drivers (DUH)
Samba 2.0
IP Masquerading
Apache

uucico need to be run out of inetd, with an entry in /etc/inetd.conf

uucp stream tcp nowait uucp /usr/sbin/tcpd /usr/lib/uucp/uucico -l
Be sure to send a "kill -HUP PID" to the running inetd process after
updating /etc/inetd.conf.
Depending upon how Taylor UUCP was compiled, you may need to setup
the password file as /etc/uucp/passwd. Be sure that user "uucp" has
permissions to read the file.
You can verify that things are working by doing a "telnet hostname
540" from the remote machine to verify that the changes you've made to
inetd are working and that you can login with the username and password
specified in the uucico password file.
If you can login okay you should get an "Shere" prompt.
BTW: This question really belongs in comp.mail.uucp.

Subject: Re: Problem in using uugetty/PPP server
Date: Mon, 25 Jan 1999 17:52:21 -0000
You don't say if you need to login in to your server first using an account
which fires up ppp in non silent/passive mode
or whether pppd just runs on your server on each serial port all the time.
I have a way of doing ppp without using mgetty+autopp or uugetty but just
the plain minimal agetty.
It works with linux clients or win95 clients dialing in!!
Here our two modem ras server has these entries in inittab:
d0:345:respawn:/sbin/agetty -h -i -I 'AT&F0E0Q1&D2&C1S0=1\015' -n -l
/etc/ppp/pppstart 57600 ttyR0
d1:345:respawn:/sbin/agetty -h -i -I 'AT&F0E0Q1&D2&C1S0=1\015' -n -l
/etc/ppp/pppstart 57600 ttyR1
replace ttyR1 with ttyS0 or S1 etc....
the pppstart script does only this:
#!/bin/sh
#
#
/usr/sbin/pppd
What happens is that init runs agetty which configures the modem
The response from the modem is enough to trick agetty into thinking it needs
to run the login program
but in this case is replaced with pppd.
Now use an options file like this:
# debug
disconnect "chat -- +++ OK ath0\r OK"
netmask 255.255.255.0
asyncmap 0
crtscts
lock
modem
silent
lcp-echo-interval 30
lcp-echo-failure 4
ipcp-accept-remote
bsdcomp 0,0
deflate 15,15
require-pap
# these options for win95 dial in clients only!!
ms-dns x.x.x.x
ms-dns y.y.y.y
ms-wins z.z.z.z
replace the x,y,z with ip addresses.
For each modem we assign ip addresses in options.ttyXx
local:remote
Now you can dial in from a win95 pc!!!
Just put in pap-secrets:
username servername password *
servername=hostname part of your server
username=win95 ras username or user in options on client
To dial in now as well using linux on the client machine use the normal
ppp-on scripts but have an options file like this:
x.x.x.x:0.0.0.0
-detach
connect "/usr/sbin/chat -v -f /etc/ppp/chatconnect"
lock
defaultroute
modem
/dev/cua1
57600
crtscts
# debug
asyncmap 0
bsdcomp 0,0
deflate 15,15
noauth
user [put a username here which must be in pap-secrets on the server. equiv
to username on win95 ras.]
and make a pap-secrets file on the client like the one on the server.
x.x.x.x is the ip you want or put 0.0.0.0 if you'll accept one from the
server.
The chatconnect script is like the ppp-on-dialer script but it doesn't need
to login.
i.e.
TIMEOUT 60
ABORT ERROR
ABORT BUSY
ABORT "NO CARRIER"
ABORT "NO DIALTONE"
"" "+++AT&F0H0L0"
OK "ATDTnumber"
TIMEOUT 75
CONNECT ""
You will need IP forwarding in the kernel on both machines and you will need
to set up your routing in the ip-up script on the server and possibly the
client if your feeding a small LAN.
Hope this helps
