Subject: using ISP's proxy -- how?
Date: Thu, 17 Jun 1999 21:53:28 +1000
My ISP uses a proxy server and while I have found the settings in
Netscape,
is there a HOWTO or doc on setting-up and using a remote proxy
URL::port.
I cannot find an option that looks like this in pppd.
Admittedly my understanding of the subject is limited, but if a remote
proxy
exists on your ISP then shouldn't my internet clients other than
Netscape know
what this adress is?
This subject (or terminology) seems to be absent from any of the PPP-*-
HOWTO's
I've read ---- so far!!.

Did you enable EXPERIMENTAL in the config? You also need to have IP
Masquarade enabled.

You should be able to use the policies tool with the win9x cd to store the
workstation registry anywhere you want then go to each workstation and tell
it to use user level seciurity and where the file is.
Not tried with linux but used with a win95 acting as a basic server once.
worked fine.

Subject: double nic problem with 2.2.x
Date: 17 Jun 1999 11:58:28 GMT
Hi
I have a problem using two networkcards in
kernel 2.2.{9,10}, probably other 2.2.x's too.
The problem is that I can only reach the nic/IP that has the
defaultroute, from outside our network. The two nics are connected
to two different ISPs.
I have routes for both networks, and I have a correct defaultroute.
The networks card are 1 AMD PCnet32 FAST+, and 1 3Com 3c509b.
Any ideas?
thanks
Robert

could you run ifconfig and tell us the result?
seems like a case of routing gone astray to me.
how do you start the modem- anything like ppp-up or kppp or so?

Subject: Terminal sharing Sage on Linux server
Date: Thu, 17 Jun 1999 12:57:22 +0100
If I run Sage for dos multi user like Line100 on a linux server can mulitple
people run it from their win95 workstation through terminal emulation
software.
The reason I ask is that Sage Line100 tends to run the Sage.EXE from the
server and pull a 100MB database over the network constantly, hense my
customers network is dog slow.
To add to it they want their remote sites linking via a VPN router which is
obviously going to be impossible as these remote sites want to run the Sage
over the VPN.
Any suggestions.

Subject: DirecPC or ISDN?
Hello All,
It seems the best I can get out of my house located in a rural area
is 24k from my (56K) modem. There is no cable TV here, nor will there
ever be (we use a satellite). DSL is a non-issue as well.
I need to work from home using SSH to get to work and run X apps (Xemacs
specifically) remotely and use a web browser. Compressing SSH, and
forcing
XEmacs to use the local X Servers backing store results in OK
performance
over the modem, but it leaves a bit to be desired. To compensate, I've
turned off the menu and scrollbar and un-3d'ed the modeline. FWIW, my
home network is an old 486 running RH 4.2 doing IP Masquerading for my
Linux box where I do most of my development work. There are other
computers on the home network, but they don't really figure in this
scenario.
Bell Atlantic offers Virtual ISDN (which costs more than ISDN), however
it's quite expensive. I'm still considering it. I think ISDN would work
out since it wouldn't change much of my current home network (replace
analog modem with the ISDN modem). I also don't know if ISDN will really
help - if my ISP is bogged down, which they appear to be at times, will
ISDN be any better than a regular modem?
DirecPC looks quite affordable, but they don't support Linux. There is
3'rd party software available, but I don't know how it will fit in with
my home network/IP masquerading scenario. I also don't know if DirecPC
will lend itself to the type of work I'm doing. Is there any latency
for each "download" session?
Does anyone here have experience with ISDN and/or DirecPC running X
apps remotely? I'd like to here it, or any opinions before committing
to either. Thanks!

Date: 17 Jun 1999 12:08:53 GMT
The error means that this Win95 machine thinks that something invalid has
happened and wants to tell the machine who sent the data it considers bad.
Somehow, it gets that machine's address wrong and sends it to the broadcast
adress, that is, all machines on the local net.
As far as I understand this error, this is a problem with that Win95 machine,
so you may just ignore it (or block it using a firewall rule) or fix that
machine.
Now, if you ask why Kernel 2.0.36 didn't show that error: I think that's
because it either didn't consider this wrong or just didn't show a message.

if you have one machine where the os KNOWS the netcard -
if you can get one MAC-adress ( and we presume here they are all the
same) - there is data somewhere in the web to resolve MAC-adresses into
manufacturer.
( you could install win9x just for that purpose and hope for
auto-detection working correct)

I just had a major problem with a bad network card on a Linux server. It
was a Realtek based NIC. It was causing all kinds of problems on a mixed
Unix and Windows network. The Linux box even locked up! I have never
seen that before, because Linux is very stable; more stable than
anything else I have seen. Anyway, I replaced the network card with a
3-Com card and everything is smooth as silk now. I don't know if the
driver is bad for the card or if the card went south (most likely). My
client was losing faith in my suggestion of using Linux, but now they
love the situation.

You ask how to tell your pppd to use a proxy. Well, pppd deals with IP
connections, while proxys are used in connection with HTTP/FTP/whatever
so everything concerning proxys must be set up in the clients (or you
could use transparent proxying combined with some other stuff, but that's
quite complex and IMHO not worth the effort.)

It can't be a hardware problem since it works with exactly the same
hardware under Win98.

Well, it is not my gateway. I'm trying to connect to an existing
network, and I don't have access to the gateway. However, I can't ping
myself from a friends machine on the same network. All I get is 'Request

I believe I've found the problem. Thanks! Now I just need to find a
solution. :)
Here's the output from tcpdump when I try to ping my gateway:
bash-2.02# tcpdump -ieth0
tcpdump: listening on eth0
13:42:32.442276 arp who-has 172.23.0.1 tell trynis.student.uu.se
13:42:33.439724 arp who-has 172.23.0.1 tell trynis.student.uu.se
13:42:34.439699 arp who-has 172.23.0.1 tell trynis.student.uu.se
13:42:37.470111 arp who-has 172.23.0.1 tell trynis.student.uu.se
...
I guess this means I don't get a response from ARP telling me the
ethernet address of my gateway. What is the cause of this? Can't
ARP find my machine under the name trynis.student.uu.se? If so,
how do I tell it to send responses to my IP-address instead?

Subject: sharing Devices, NT <-> Linux
I would grately appreciate some help or suggestions in the following
case:
Two mashines, one NTServer40, the other Linux 2.0.35 - the problem is
that I would like to use Hardware on the linux maschine with clients
connected to NTServer with Window drivers.
Some devices just work more comfortable with Window drivers. In one
example, I would like to use the easy working copy software for the
Mustek SCSI scanner - a tool which I cannot find as a linux app.
I have no idea if my wish can be fulfilled or if drivers can generaly be
looped through other mashines.
The other thing is I would like the linux mashine to act as a secondary
server. If the Window mashine fails, all clients should work as if
nothing had happened because they automaticly connect to the linux
server. Is this possible?
