you should read Ethernet-HOWTO
uncomment the NE_RW_BUG_FIX line in file linux/drivers/net/ne.c
and aft then recomplile kernel
so OK.

I have my PPP connection working - almost. I can't get the DNS working.
I have the host.conf and resolve.conf set up according to the How-Tos,
but it still won't work. When I run nslookup with:
host yahoo.com
I get the following response:
Server: yahoo.com
Address: 204.71.200.243, 204.71.200.245
*** yahoo.com can't find host: no response from server
When I try entering the dot address manually into netscape, it opens the
page. nslookup also gives me my DNS server configuration correctly when
I first start it. Help!

I downloaded the emu drivers from creative's site - as far as I know, these
are the only drivers available? After I ran the installation script and
rebooted, X11Amp kept core dumping until I discovered I had to run the
program "esd" in the background, which is apparently the sound daemon. Now
the computer appears to be playing mp3s and wavs (a program showing 3-d
waveform graphs from sound card data appears to be verifying that the sound
card is getting something) but my SB Live won't produce any sound out of the
digital or analog ports (so nothing comes out of the speakers), although the
card works fine in Windoze. What am I missing?

Subject: UDP-portforwarding with ipmasqadm
Date: Thu, 05 Aug 1999 22:05:19 GMT
So the problem is to forward the port 6112 for use with battle.net (Diablo,
Starcraft, etc.)
from my SuSe 6.1 - box to the whole protected LAN.
I tried
/usr/sbin/ipmasqadm autofw -A -r tcp 6112 6112 -h 192.168.1.0
/usr/sbin/ipmasqadm autofw -A -r udp 6112 6112 -h 192.168.1.0
to forward the port to ALL local Workstations, but this brings no forwarding
to any machine
at all. :-((
if I use the specific adress of the local destination-PC, for Xample
/usr/sbin/ipmasqadm autofw -A -r tcp 6112 6112 -h 192.168.1.2
/usr/sbin/ipmasqadm autofw -A -r udp 6112 6112 -h 192.168.1.2
it works, but only for this single adress, and if I add more lines like
/usr/sbin/ipmasqadm autofw -A -r tcp 6112 6112 -h 192.168.1.2
/usr/sbin/ipmasqadm autofw -A -r udp 6112 6112 -h 192.168.1.2
/usr/sbin/ipmasqadm autofw -A -r tcp 6112 6112 -h 192.168.1.3
/usr/sbin/ipmasqadm autofw -A -r udp 6112 6112 -h 192.168.1.3
only the last specified host gets UDP-packets on 6112.
Any ideas how to solve this problem, so that all local hosts can send and
receive at same time ???
Thanx

Hi,
yes, another newbee with linux.... :O) problems? oh no, linux works great,
along with kde, no problem... but i can't seem to get internet working on
it! :O(
I have a cable modem ( yes and a network card in my pc ofcourse).
It's very weird, i want to use the DHCP client, but it fails: network
unreachable (though on booting i get no error).
My localhost ( loopback lo )works fine, telnet, ftp, http, ping, it al
works!
When i manually enter a netmask and a gateway (into the dhcp script) i even
get lots of output with tcpdump and arp. (i can even see the ethernet hw
addres of my gateway, though if i wanna ping it he can't find it!).
I use SuSe6.0 and when i run my DHCP client i get this:
bash-2.02# dhclient
Listening on Socket/eth0/unattached
Sending on Socket/eth0/unattached
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 4
send_packet: Network is unreachable
etc etc.
The 'unattached' part i really don't like, does anyone know how i can
'attach it' to the Internet Protocol?? ( i think that's the problem anyway).
Any help would be greatly appreciated! tried lots of things here with
ifconfig, dev, dhcp client ( and yes, ofcourse i tried to set up my ip
addres also manually, and i got the ip address ( which i could ping and
stuff) but still didn't got a gateway, er any host what so ever.).

Equivalence is still working the issue. They told me to contact them at the
end of this week to check on the results. The Phonepatch software does work
with NM 2.1x but not NM 3.x.
I get the same results as you do.
I still use my CUSeeMe software from Whitepine because they don't fully
implement ITU T.120 and H.323 protocols in version 3.x (but do in 4.x - no
upgrade for me yet on CUSeeMe software). They use static ports so can be
specified using ipautofw (Linux 2.0.x) or ipmasqadm autofw (Linux 2.2.x).
