The remotename option is needed because the NT RAS server does not give
its name in the MS-CHAP challenge.
Therefore, there has to be an arbitrary string in both pppd options and
in chap-secrets.

Does anyone know how to get a batch file to map to a workstations home
directory do a routine
disconnect and the move on to another workstation etc. All the
workstations would be entered in
by using a text file as the input. I cannot seem to get the NET USE
command to work with
the < command. I know it needs to be in a loop, but has anyone ever
tried this before or has some
code as an example.
Thanks

Everything looks fine until the pings begin to fail. The PPP interface

Do IDSN modems use the box's serial port as do most regular external
modems? The only thing that comes to mind is whether the maximum
speed of 115200 for the ordinary PC serial port is sufficient for the
ISDN connection. Although it's hard to see how this could result in

Think of it as a normal network
Now for your Linux box to get anywhere it needs to go thru a router / gatway
device, the router is NOT your network card or or anything like it.
IT is the cable modem> and it's IP address
So the Cable modem IP address is the gateway, and it happens to be connected
to one of your network cards (eth1), that has an IP address of 24.4.162.173
If your gateway is yourself, how to you get thru the gate????
All other machines connected to your Linux box <to surf say> can use the
Linux box as their gateway, but the Linux box cannot use it's self as the
gateway for it's self.

What's happened is that your init scripts have tried to load the network
before the cardbus nic is recognized. I've go the same card in another
CPi. Eventually, you may want to change the order of your init scripts,
so the pcmcia modules (i.e., cb_enabler and 3c575_cb) are loaded before
the network. In the meantime, try this: after you login, check with
"ifconfig" to verify you only have lo, then issue "network restart" (I'm
not at my pc, but I believe it's in /etc/rc.d/init.d - someone correct
me if I'm wrong, since I'm so new at linux). You should now see eth0,
and you can go about setting up your route(s).

Subject: Multiple via-rhine NICs
Date: Tue, 25 May 1999 09:24:38 -0500
I have 2 PCI NICs which use the via-rhine module. These cards are
identical (except for the MAC id, of course)
I have
alias eth0 via-rhine
alias eth1 via-rhine
in my conf.modules file.
When the module loads, it detects the first card at IRQ 10, and creates
the eth0 interface. It then detects the second card at IRQ 11, and ....
nothing. No eth1. I have swapped the second card from another
functioning machine, so I know that both cards are good.
/proc/pci shows both cards, at IRQs 10 and 11.
This is kernel 2.2.6....
Any ideas? I tried passing explicit IRQ information when the module was
loaded, but the module says that "irq" (and "IRQ") is not a valid option
for this module.
Any ideas?
Thanks,
-Eric

Subject: Solaris 7 as NFS Server for Linux

Sorry for the previsous, corrupted posting!
Dear collegues,
I have a problem with the Solaris 7, since I'm trying to let my Solaris 7
computer be the NFS server for Linux, which is connected to the Solaris 7
machine with a 10Mbps network. If I try to connect from the Linux machine
to Solaris, either by telnet or ftp, I had to wait for up to about 2-3
minutes, until I get the login prompt. And the situation is even worser
if I try to use Solaris as NFS server. I actually need to try many times,
until I'm coming into the moment, in which the Solaris server is willing
to response, and the NFS client don't stop with a timeout. Are there any
possibilities to overcome this problem?
Thanks!

Bad puppy. No biscuit for you. :-) Seriously, when someone tells you you
NEED X, Y, and Z, do not expect to leave two of them out and still have it
work. You MUST turn on "use-pap" and provide a pap-secrets file, or you
won't connect to that ISP. If putting them in gives you errors, something
is wrong with your pppd version. You may have to rebuild pppd; if so, my
page (below) will walk you through that.
>It appears the connect script fails (the ppp-on-dialer chat script ?),

You may still be looking for a username and password prompt, and on a PAP
system you WILL NOT receive either one of those. The script should end as
soon as the modem finishes dialing; pppd takes over and does the PAP
negotiation to log you in. (That's what PAP is all about.) If your script
is waiting for an "ogin:" prompt, that script WILL fail.
>If someone could please help me or recommend a better way to get
>online, I would deeply appreciate it. I am extremely frustrated.
See http://www.brasscannon.com/Linux/ -- skip over the "recompile the
kernel" stuff for now and go directly to the part about configuring PAP.
(You don't have to set up demand-dialing if you don't want it; just take out
the "demand" line in the "options" file. That's the only part that requires
rebuilding pppd as far as I know.)
But do check the part about adding compression schemes to the modules list;
you can connect without that but it'll save you trouble later. I'd print
the whole page out -- you may want to come back and add more features
later, once you're connecting reliably. So:
* Replace your chat script and options file with my examples;
* Give it the correct phone number (555-1212 probably won't work ;-)
* Provide a pap-secrets file as described, protected so only root can
read it;
* Type "pppd &" as root. (You'll want to fix it so regular users can do it
eventually, but let's take it one step at a time.)
I bet it'll connect right away. Try to ping your provider's IP address (you
do know it, right?) - that should work. Use Ctrl-C to stop it. Then try to
ping it by name. If the latter doesn't work, you'll need to tell your
system how to find their nameserver so you can resolve names; info on doing
that is on my Web page.
As soon as you've done that, you're good to go with Netscape and any other
'net software you want to use. Then you can think about adding demand
dialing, IP masquerade if you have other networked machines, etc etc. Or
not, your choice.
Good luck!

OK. That above \d\c just locked up my ppp 2.3.7 now. Having upgraded.
I managed to help ctvm. I tried their help, still no success.
Though I wasn't previously using all caps on my userid. One bullet down.
Dejanews won't let me cut&paste my latest ppp log output.
Also, ctvm says their static ISP is "10.0.0.1", which I have specified.
So, what else could it be? I'm running Linux 2.2.6 now BTW. Just need
Cablemodem running.

There are a few people who've written server software that runs under
NT/95 which redirects communications from a TCP/IP socket to a comm
port. There is at least one GPL and one proprietary solution.
Similar programs (termpkg...?) exist for Linux as well.
Check Simtel for the Winderz version.

Hi !
Use "ipfwadm" commands to define your firewall filtering, to be placed later
in "/etc/rc.d/rc.local" by example. Many examples in "firewall & proxy" HOWTO.

Subject: Re: HP JetDirect
Date: Tue, 25 May 1999 18:47:39 GMT
The HP JetDirect EX series of print servers are exactly that; print
servers. They will broadcast SAP packets for IPX networks and with
function as a completely independent lpd server for Unix environments.
By default, the JetDirect will try to obtain an IP address from a BOOTP
server. If you don't have one, you'll have to use JetAdmin to configure
the IP address; however, you can't use JetAdmin without IPX on the wire.
Once you have an IP address configured, you'll need to add a section
similar to the following in /etc/printcap on your Linux box.
remote_printer:\
:lp=/dev/null:\
:rm=11.22.33.44:\
:rp=text:\
:sd=/usr/spool/remote/remote_printer:\
:lf=/usr/adm/lpd-errs:
The 'rm' parameter is the address of the JetDirect server. The 'rp'
parameter is the "printer" on the server. That may sound odd because
you may only have a single printer attached to this device; however,
what this allows for is a remote server with many attached printers
(including HP JetDirect EX3 external print servers, which have three
parallel ports to attach printers). Use the "text" printer for plain
ASCII documents, use the "raw" printer for documents which are PCL5.
Also, on the EX3, there are a total of eight "printers" available: text,
raw, text1, raw1, text2, raw2, text3, raw3. The number refers to the
port that the printer is attached to; text and raw are equivalent to
text1 and raw1.
