can you do this experiment for me, if you have the boxes for it?
set two linux 2.2 systems on a private wire (rolled cable), with the
cards of your choice. then send a fast ping stream to the other:
ping -s 1000 -f <target>
if it lives for several minutes (an hour would be nice) then I would
be willing to get a card like the one you used and try it here.
currently, my tulip cards can be frozen solid in less than 1 minute
with 2.2 kernel. again, 2.0.36 this experiment passes just fine. so
my system, wiring, etc is all fine - its the changes in the driver
and/or kernel that are at fault. and have been this way since 2.2.0.
rather than wait for the driver to stabilize, I'd like to get a card
that has a stable driver -today-, and when the tulip is back to
working again, I'll consider switching back.

You don't say what operating system is on the client-pc. I'm
assuming it's either Windows 95/98. You have to get into the
networking setup of Windows and place the IP address of the Linux
machine in the section where it asks for the number of the gateway
machine.
If you are running something like squid, wwwoffle, or junkbuster on
the Linux machine, the port numbers that this software is using is what
you would need to configure Netscape to use.

Subject: Mounting the Samba Server with Linux???
Date: Sat, 08 May 1999 00:39:23 -0600
Hi All,
I have a small home network going. Two computers,
Dual Boot, Redhat
5.1/Win95 and server running Redhat 5.2 & Samba. I
have Server/Samba
working fine with Win95, I can log in and see all
the available shares
etc.
Currently when I boot into my Redhat 5.1 (the dual
boot machine) system
it will mount the DOS partitions (i.e. C-Drive and
D-Drive) on my
Windows 95 system through fstab.
Should the Samba server make those partitions on
the Win95 system
available to the Redhat 5.1 system, instead of
doing it through fstab?
How should I mount the available shares on the
Samba server with Redhat
5.1? Should I place the smbmount lines in the
etc/rc.d/rc.local file? Is
that the preferred method?
Is there any special syntax that need to be used
in the rc.local file?
Just trying to set it up the most logical way.
Thanks
Joe

I've had a 3c509B (Etherlink III) for a year now on a 10MBit & T1. Since
kernel 2.2.0 I've used it.
It has never ever failed.
I heard that some people encountered problems regarding PnP om this card
but it is easy to disable PnP.
I've never had any problmens though.
These cards are very cheap at the moment.

Did you download IE5 for Linux? (Is there an IE5 for Linux??? I only
use Netscape.)

You need to know where you installed Netscape 4.51. It probably was
installed into /usr/local/netscape, or perhaps /opt/netscape. One way
to find it is to use the locate command:
locate netscape | less
which will show all the places where files/directories that have
"netscape" as part of the name. You should be able to tell which is
4.07 and which is 4.51. On my system, the executable file found is
/usr/local/netscape/netscape; Your Mileage May Vary.
Digression: if locate doesn't work, you need to create the database --
it gets created on a daily basis by a "cron" job, but if you don't leave
your computer on all the time, that job will never run (it is schedule
to run at about 3:00 a.m. or so), and the locate database will never be
created. To create it yourself, you can run that cron job manually,
like this (as super-user):
/etc/cron.daily/updatedb.cron
OK, now that you know exactly where the Netscape 4.51 executable is
located, you can simply type the full pathname each time you want to
execute it -- but that much typing is boring. You could add it to your
path (in my case, by a statement like this, in your .bash_profile file
-- change the path variable to your own location, of course):
PATH=/usr/local/netscape:$PATH
export PATH
But I prefer to create a symbolic link in /bin, like this:
ln -s /usr/local/netscape/netscape netscape
Since /bin is already in your path, you can now execute Netscape 4.51
simply by typing "netscape" at a command line.
If you still get Netscape 4.07, it is because the path to that version
is ahead of your normal path -- that is probably in your .bash_profile
file, either remove the path to 4.07 entirely, or move it so that /bin
is ahead of it (for the symbolic link method) or that
/usr/local/netscape is ahead of it (for the path method).

No experience with this stuff, but FWIW I think there may have been an

Why sould the default gateway be the WIN95 interface? If this is just a
local network, you probably don't need a default gateway. If you setup your
linux box to dial to the internet, it's inteface (192.168.0.1) would be your
default gateway.

The first network card is for connectivitie to the internet,

ip-adress x.x.x.200 and card 2 x.x.x.201.
If i ping from the machine to the internal net i get replies, and if i
ping to the internet i also get replies. But if i ping from the internet
to 1 of the machine behing the firewall it
doesn't reply. It looks like Linux isn't forwarding the

The NE2000 ethernet driver is probably already in your kernel, or
loadable as a module. Can't remember exactly how I did it, but I had to
putter about with insmod, changing the irq's and the base address before
mine started working. To see how to use insmod, read
/usr/doc/HOWTO/NET-3-HOWTO.and see if you can find a reference to all
the valid base addresses and irq's somewhere in your card's manual.

Can you outrule the HUB from being a borderliner? Your two machines
is already a twisted pair, it seems, do they need any wire? ;-)
Well anyway, try to get a crossover tp, and dont use the HUB.
And if the problem stays the same, go http://www.smc.com and get the
setup-util for the nic. (It fits on 1.44Mb floppy, so if it is
bootabel.) It have som diagnostic on the card. And also an
echo-server or something wich let you test if the nic's are working
properly. You need a crossover tp for that, if you dont use the HUB.
Having two SMC-Ultra NIC's you set up the one as a server.
And you can look over setup on the nic. There is a 'zero-waitime' (if
problem, turn it to off) and choices for wich interface the card uses.
(combo-card?)
An if you get it to work that way. Then the real problem must be
somewhere else.
What kind of SMC-Ultra is it?
(I got some 'SMC Elite 16 Ultra (8216, 8216C, 8216T)' very good in
transmitting packets, never any problem with them. Shared memory
cards. Are the memory-area shadowed in bios? I dont do that.
Bootproom's?)

IP forwarding is nothing other than IP routing. IP masquerading is n:1
network address translation. In order to masquerade usefully, you need
to perform routing, aka forwarding, as well.

These are the most basic masquerading rules. What I don't like about
them is the '-a m' bit in the forwarding rule. First of all, it seems
to imply to many that forwarding and masquerading are pretty much the
same (which they aren't). Second, it's inconsistent within ipfwadm.
Rules can be told to accept, reject or deny packets, those are the
three commands there are. Masquerading is an option that makes sense
only in packets accepted for forwarding, but IMHO the proper line is:
ipfwadm -F -a accept -S 192.168.1.0/24 -D 0.0.0.0/0 -m
I'll shut up now. :)

Neither have I, but the syntax doesn't look a lot more difficult. I
haven't switched to 2.2 yet either, though.

I got your answer, but it hasn't worked out!
So any further suggestions?

Subject: small first TCP/IP network with linux and mac
Date: Sat, 08 May 1999 10:20:23 -0600
I want to set up a Mac/Linux TCP/IP network. The machines are already
networked on a 10 base T network. How do I set up the linux machine? I
already know what to do with the Macs beacuse I have made a small TCP/IP
network with them that worked. For now the network won't be connected
to the internet. I am running redhat linux I was thinking of using the
class C network: 192.168.0.0 - 192.168.255.255 since it's set aside for
non-internet connected networks. How do I go about this? I would like
to use netcfg since it's graphical and it's my frist try at network of
this type.

Have you checked that /etc/inetd.conf point to the ftp and telnet daemons
(should be /usr/sbin/in.ftpd and /usr/sbin/in.telnetd respectively,
IIRC), and that the ports are set up correctly in /etc/services?

Hi. I'm a Linux newbie, so please take that into account. I'm trying to
get Linux set up to work with my cable modem (@home). I know this is
possible, but i can't seem to get it working. I've been trying to set it up
with a static IP, but to no avail. I want to try DHCP, but when I try to
enable it through KDE interface it won't save it. dhcpcd (client) is
installed. I'm using the Caldera version with the 2.2.5 kernel. Could
someone pleeeease help?! Or at least point me to where I can get detailed
info. on this. Thanks in advance :-). oh yeah, I have a 3Com Etherlink III
3c509b card, and Linux does detect it.
