Subject: DTMF authentication for ISDN router
Date: Wed, 24 Feb 1999 06:16:08 GMT
Here's the situation.
I have a small LAN, and a number of static IP addresses provided by my
ISP. (mask 255.255.255.240)
A linux box (486, RH5.1, kernal 2.2.1) acts as a dial on demand router
for my LAN, using the "demand" option with pppd. The ISDN connection is
made whenever I
This works fine when I'm sitting at my desk at home. But suppose I want
to access my LAN from work, without using a modem, i.e. using my
company LAN. In this case the link from my home LAN is down, and I
cannot bring it up from work.
I do not want to dial up my LAN using a modem to switch on the LAN, bu
rather make a simple voice call to the router using a regular analog
phone and analog modem connected to the serial port. I want the router
to ask for authentication, which would be provided in the form of a PIN
number using DTMF tones. On authentication, the router would run a
script to bring up the ISDN link and expose my LAN to the Internet.
Does anybody know of some code to run the authentication software? The
principle seems the same as running voice mail software on a PC, or a
fax on demand service.

Reply-To: [EMAIL PROTECTED]
I've got a small network of Win95 machines connected to our new
Linux server box. It all seems to (mostly) work, but I've a
couple of problems relating to PPP/diald.
Within the Linux box I can initiate an on-demand dialup with
ping/finger/Netscape etc. Once the link is up, all the machines
on the network can reach Internet courtesy of masquerading.
What *doesn't* happen is that generating internet traffic on any
machine on the LAN does not trigger the dial-up to occur. I'm
wondering if this is to do with permissions? Any ideas?
Secondly, the syslogs report complaints by pppd, even though the
link seems to work perfectly. Any ideas on this one:
pppd[798]: sent [IPCP ConfReq id=0x1 <addr 194.222.68.214>
<compress VJ 0f 01>]
pppd[798]: sent [IPXCP ConfReq id=0x1 <network 0> <node

Subject: Intel EtherExpress 16, Kernel 2.x Woes
Date: Thu, 25 Feb 1999 13:15:03 GMT
Hi, all...
I have seen other similar posts regarding this problem, and thought
I'd add my two cents...
My card is an Intel EtherExpress 16. Under all previous 2.0.x
kernels, as well as under Win95 and 98 this card has been totally
problem-free.
Howewer, since my update to the 2.2.x series kernels, I have
experienced the following messages. Each time the messages appear
(usually only during heavy network traffic such as an FTP), the card
drops offline and I need to reboot to re-awaken it.
eth0: CU wedged, status 0240 0000, resetting...
eth0: i82586 reset timeout, kicking...
eth0: i82586 not responding, giving up.
In addition, I have seen this one more than once (although the system
seems to be able to keep going after this one...)
eth0: tx interupt but no status
The card is identified as follows by the driver...
Etherexpress 16 at 0x340 (IRQ 10, RJ45 connector, 16-bit bus, 64k RAM)
This problem has occurrred with each of the following 2.2.x kernels...
2.2.1 (official Linus release)
2.2.1 each of the Alan Cox releases
2.2.2 (official Linus release)
2.2.2 (so far ac1 and ac2)
Under all versions of the 2.0.x kernels that I tried (2.0.0 through
2.0.36) I never had this problem. As well, as I said, "that other OS"
has no problems.
I cant believe this would be a hardware setup issue (IRQ/IO conflicts,
etc.) since it has worked flawlessly in the past.
As well, I no longer suspect my card just may be simply "going bad",
since everyone else using the same card has also seen the problem
appear when the switched to the 2.2.x series of kernels.
For those who will waste time asking, my system is a fully-loaded
Pentium 200 (non-MMX) with 128MB RAM, running RedHat 5.2 with all the
latest updates from updates.redhat.com installed (as well as all of
the "kernel-2.2 updates" available at the same site.
If anyone has any further info (or requires same from me) please let
me know.
Thanks, all... in advance.

Weird, I don't believe that'll work. ppp over isdn is completely different
from ppp over a normal modem. ttyI* are used for X75 communication with
BBS'es, certainly not for communication with the internet.
You need a completely different pppd, ipppd, and should configure the card
using isdnctrl.
Maybe you could use kisdn (kisdn.headlight.de) for configuring the card,
I've never tried it.
Also, visit this page: www.wurtel.demon.nl (however, I could be in dutch,
I'm not sure).

Subject: mountd: unable to register
Date: Wed, 24 Feb 1999 12:04:24 -0500
I am trying to mount a NFS volume over a PLIP connection, but am not
having any success. The problem seems to be that rpc.mountd and rpc.nfsd
won't "register" with portmap.
This has been driving me nuts for the past week; I have not been able to
find a reason why this is not working. I hope someone out there who
knows more about these things can help me!!
NFS-HOWTO s.3.3 says "Start portmap, and check that it lives by running
ps aux. It does? Good."
I type "portmap".
I type "ps aux", and get (amongst othe things) the following:
bin 335 0.0 1.0 760 336 ? S 10:37 0:00 portmap
which I assumes means portmap "lives".
Here are the contents of my /etc/exports file
# exports file for desktop
/Bruce laptop(rw)
/Bruce/Updates laptop(rw)
(where "laptop" is the address of the laptop that I want to give NFS
access
to over a PLIP connection.)
I start up the PLIP connection
ifup plip0 laptop
and am able to PING between laptop and desktop.
I type
mount /mnt/desktop
on the laptop, and get the error
mount: RPC: Program not registered
I type rpc.mountd on the desktop and get the following error
Cannot register service: RPC: Unable to send; errno = Invalid
argument
portmap and nfs are included in the sysvinit, and are supposed to run at
bootup.
I checked in /var/log/messages and found the following lines:
Feb 24 10:10:45 mountd[156]: unable to register (mountd, 1, udp).
Feb 24 10:10:46 nfsd[164]: unable to register (nfsd, 2, udp).
I hope someone out there can help me figure out what it is I am doing
wrong!
Thanks, Bruce

I have your run of the mill 10.1.1.0 network with Linux 2.0.36
performing IP Masquerading from the eth0 to the ppp0.
The Linux firewall is eth0: 10.1.1.1
ppp0: 1.2.3.4
I have a telnet client running on 10.1.1.20
I want to telnet into the 10.1.1.20 box from outside my network on
some arbitrary port, say 9999. So "telnet 1.2.3.4:9999" and have the
firewall translate all port 9999 packets and forward them to 10.1.1.20
on some port (I guess 9999 would work) What ipfwadm commands do I
need to run to do this?

I don't know what the guys did with samba 2.0.2 but smbmount does NOT work
well... I liked the old system better.
This should work (a bit messy though):
smbmount //BUBBA/D -C -P shared -c "mount /mnt"
I don't know if this is the way its supposed to work...I've had a quite a
few run-ins with sudden connection-drops and file-system-errors. Don't
worry, though, it won't corrupt anything...

Reverse it, append in-addr.arpa. and use it as an argument to
"host". e.g. "host -a 122.169.23.138.in-addr.arpa.". It doesn't
necessarily get you the same name you started with though. The
actual www name may be an alias or may have several IP addresses
each being a different machine in a server farm.

Date: Fri, 26 Feb 1999 02:02:15 -0500
The -I switch tells the compiler to look in the specified directory for
whatever headers may be in there (as in 'Include" this directory in the
search). If you look at the source code, you'll see a number of headers
used to define various functions, et cetera... used in the program... If
you don't tell the compiler where to look for the headers, it won't
compile. The end part of the compile statement performs a logical AND
operation by testing if that specific file exists and ANDing it to the
result of the macro. I believe it will evaluate to either a 1 or a 0 but
what this does for the compile, I'm not sure, except that my tulip
driver wouldn't work without that portion of the compile statement. If
you do a 'tail' on the source code, it'll provide the proper compile
statement you should use for your platform.
