The card you are using has a driver written specifically for Windows. I've
been told that many of the functions normally executed by the driver have
been moved into the firmware on the card itself, any most of those functions
are windows-based (ie. functions Linux expects probably won't be there).
I can't tell you for sure, but my feeling is that this NIC will be as
useless under Linux as the WinModem is.

I had a similar problem a few weeks ago. I have 2 PCI cards and got the
same "Delaying initialization..." message.
All I did was to use the Linksys floppy and, using a dos prompt, gave the
cards IRQ's 10 and 11.
After this, I rebooted and Linux recognized both cards with no problem.

Subject: Internal linux host and dns failure
Date: Thu, 22 Jul 1999 00:42:14 -0400
Hello everyone. I have a strange problem here that
I can't find anywhere in the howtos or dejanews. I
run a small network with 2 windows 98 hosts and one
linux host all behind a simple firewall with a
modem connection. I run diald and all of the hosts
connect successfully once dialdc attaches the network
to the outside. However, after my linux host connects
to the internet, and the internet times out, when it
connects again it cannot get dns from a remote
server. At all. When something tries to resolve a
name, like netscape, it just sits there and
eventually times out. The windows hosts have no
problems with this, only the linux host, and they are
accessing the same external dns server. I'm running
the most simple firewall imaginable:
echo 1 > /proc/sys/net/ipv4/ip_forward
$IPCHAINS -P forward DENY
$IPCHAINS -A forward -j MASQ -b -s $MYNET
The gateway is a P100 running Redhat 6. I'm running
version 0.98 of diald. Everything works beautifully
from the windows hosts (they attempt to connect,
diald dials the modem and connects, and they get
their responses). I cannot understand why the linux
host would be unable to get dns. And only after a
successful connection has been terminated and the
host attempts to connect again. Any help would be
greatly appreciated.

If you want to access public shares without using a password, just put
security=shares
in the global section. This was default in older samba, but the default is

telnet is easy - as already pointed out by antov- once tcpip is working.
( you can ping each other? - then you can telnet nt > linux).
but:
nt does NOT include most unix-server-tools, so its not a telnet-server
for instance, means telnet can only go one way.
and, nt does NOt include a nfs -client ( or server), you will need to
buy a commercial product here - and they cost you!!!
so, if you are asking about sharing files , look into samba.
its easy, and its free, and is supposed to go both ways -
( i have to admit i'm having troubles with the smbmount-part myself,

Subject: Linux VPN Masquerade and LAN access
Date: Thu, 22 Jul 1999 00:46:28 -0400
Hello,
** networking newbie alert **
I just set up my new Slackware Linux box with the VPN
masquerading patched 2.2.10 kernel, but I don't have full
access to my local network when I'm connected to the VPN!
Here's my config:
A) Win98 box (using Bay Networks Extranet Access Client- VPN)
B) Win98 box
C) Linux Slackware 2.2.10 vpn patched kernel w/ 2 NICs
connected via SDSL
Before I connect to the VPN, I can ping all machines from all
other machines, I can browse all machines using
Network Neighborhood (SAMBA for the Linux box) and I have
internet access from all boxes. Perfect.
Once I connect using the VPN client on my Win98 box A),
I can no longer ping from C) to A), from A) to C), from A) to B)
or from B) to A). The VPN client machine being the obvious
HOLE here.
I *can* ping from B) to C) and from C) to B) and can still
browse (via network neighborhood) and UNC between A) and B).
And all machines have internet access although only the
A) Win98 box has access to the VPN resources.
So, I'm wondering what is wrong with my networking either on
Linux (I'm assuming it's there) or on the A) win98 box?
I've been reading the how-to's but can't quite find the answer(s)
I'm looking for. The documentation on this particular setup is
actually quite limited....VPN masquerading.
Can anyone help?
Also, out of curiousity, has anyone found and ran an IPSec VPN
client on a Linux machine? I haven't found one yet, but I wonder
if all of the machines in your LAN would then have access to the
VPN resources because the whole setup is now masqueraded thru
that gateway Linux machine.
Thanks for any assistance.

Subject: RH6.0 Networking problem
Date: Wed, 21 Jul 1999 23:39:28 -0700
Hopefully someone out here can help on this one. I have a Digital
PWS 266i (basically a PII box) which until recently was running
RedHat 5.0. It has a Digital Etherworks III network card in it,
and everything ran fine. The system also runs NT4SP4 (evil evil)
and networking continues to run fine from there.
Yesterday I attempted to upgrade the system to RH 6.0. The upgrade
went fine, but there is now a Mysterious Networking Problem. The
network comes up correctly (ifup eth0) and works right (it can ping
to the outside world) but the moment it receives an ethernet
packet, it goes crazy - the network traffic light starts to blink
rapidly and the network becomes essentially unusable. In this
state, the system can still ping itself via its real ethernet
address (not the loopback) but it can't see outside itself, and
other machines can't see it.
If I take down the ethernet interface (ifdown eth0) it continues
to blink like that, but when I bring the interface back up again
it suddenly stops - until another packet comes in. Similarly if
I take down the ethernet, unload the tulip module (which is the
driver it's been using, both under RH5 and RH6) and reload it, as
I reload the module the blinking stops.
The IRQs and so on are all set correctly, checked against settings
that work under NT and RH5.
Has *anyone* heard of a problem involving this card or the network
drivers with RH6? Any ideas as to what could be causing this?
All help is appreciated -

Thanks in advance for any help:
I'm using potato, with an ADSL connection. (running dhcpcd)
All outgoing connectivity is fine. However, after about 5 minutes of
network inactivity, the machine is unreachable from beyond the DSL
modem. Any outgoing activity will again restore incoming
accessibility for again, about 5 minutes.
Is this likely a "feature" of the ADSL network I'm on? Or something
I've overlooked in my network configuration?

Will the other machine have an externally contactable address? Basically,
you're webserver is the firewall, tighten security up on it. I'd recommend
putting the other machine on an IP under either the 10 or 192.168 networks,
then doing IP masquerade under Linux.

Everytime I try to install the Intel Ethernet Pro 100 on-board card

I recognize the source of the problem might stem from that the Intel

Wondering if someone out there might be able to get an answer to this ...
Why, after I start PPP (using kppp or Gnome-ppp), do any !and! all window
managers stop launching applications ?
EG: Launch Gnome-PPP or kPPP, connect to the internet, then try to launch
any other app and nothing will happen. It's like the window manager (Either
Gnome, KDE, and/or Enlightenment) just stops taking instructions ?????
Gnome Panel, KDE, and Enlightenment each refuse to start another(single)
application until after the PPP connection is terminated, then everything
works fine !
Any comments or Suggestions ??
Thanks for your time on this one !!

The choice to delay network initialization is done by the various
network
boot scripts - S10Network (in /etc/rc.d/rc2.d), which calls ifup (in
/etc/sysconfig/network-scripts) Typically that response means that the
network controller modules are in wierd shape - try booting in
single-user mode, manually unloading the network modules, and putting
them back in. If that doesn't work, check /etc/conf.modules, or try
reading through all the ifcfg-eth0 and so on in
/etc/sysconfig/network-scripts.
One of those should have your problem.

Hi Mark
1 to get ip_forwarding to work you must use echo "1" >
/proc/sys/net/ipv4/ip_forward in your /etc/rc.d/rc.local file. The file
ip_forward in the proc file system must have a one in it.
2 In the kernel options: General Setup -> Sysctl Support on
File Systems -> proc filesystem on
then your ip_forwarding will be on.
I am not too sure of the IP masqurading at the moment.
Hope this helps.

They're related. Routing is the elaborate process by which messages are
forwarded to a target host along a chain of ten or twenty intermediate
locations. The automatic generation of routing paths is sometimes kinda
flaky.
The best thing to do for this is to do the first step in the routing
manually. Call up your ISP or local sysadmin and ask them for the IP
number of your gateway server. Then you can explicitly specify this as
the default first step in a route by sticking a line at the end of your
rc.local file
route add default gw FOO
(FOO = the address) There's actually a cleaner way to do this involving
a file called "static-routes", but I can't remember the details...
If the routing works when you first start up your machine but then stops
after a few seconds/minutes, then you should turn off the gated and
routed daemons; they try to automatically construct routing tables every
few seconds or so, but occasionally they completely mess up and stomp
your tables. If you turn them off you will need to put in the static
routing information like above.
Hope this helps -

XWin32 has the ability to show all errors that occurred on the target
machine. Have a look there. If you can't see anything due to the
graphical login, switch to runlevel 3 = no gfx login.
My guess is that no windowmanager is being loaded (so your login is
accepted). Enter something like "wmaker &" in your XWin32 command box.
