OF course this isn't true anymore. The kernel 2.2.12 has support for
OLYMPIC IBM T-R cards, pretty much all PCI from IBM that aren't Lan Streamers.
The drivers work pretty well, too (though I can't get more than about 400 k/sec
across them on a quiescent ring)

Hi I'm a newbie needing a bit of advice on connecting my two computers.
can anyone help?
I have a mac beige G3 which has macos on one partition and linux-ppc on
the other, I also have a pc with linux/windows installed. I'd like to
network these to exchange files, and preferrable share printer also (and
preferrably by the cheapest way possible-- 'cause I'm a cheap-skate;-) .
I'd like to know what options I have and what's a good place for
information, besides the LDP network admin guide and the how-tos which
I'm looking at already. Can anybody tell me specifically where to find
hardward compatibility info for connecting macs and pcs for either a
linux to macos or linux-to-linux-ppc? Somebody told me I might be able
to get by without a hub if I setup a 10TBase2 ethernet connection, but I
wasn't sure if that might just be a windows-to-windows option.
thanks for any help!

If you know perl, you can use the Net-RawIP module to forge your own

Subject: Need help with route
Date: Sat, 04 Sep 1999 15:46:37 -0500
Hello all,
Here's my problem. I'm running slakware 4.0 (kernel 2.26) and have
compiled all networking options (including IP fwd and masq) into the
kernel.
I am trying to get IP forwarding to work with my cable modem. I have
two generic NE2000 cards installed and they seem to be working fine.
When I configure the second card with ifconfig (ifconfig eth1
10.0.0.1)it appears to be ok but when I try to enter the intranet in the
routing table with
route add -net 10.0.0.0 eth1
I get:
SIOCADDRT: Invalid argument
The routing table appears as follows however:
Destination Gateway GenMask flags
Metric Ref use Iface
10.0.0.0 * 255.0.0.0
U 0 0 0 eth1
loopback * 255.0.0.0
U 0 0 0 lo
(I have disabled the dhcpcd for this example)
Is the network entered properly? If so why don't I see the 10.0.0.1 from
the ifconfig command? I guess its obvious but I want to make a subnet
with 10.0.0.1 as a gateway. I am stuck here and I'm pretty new to linux
so can anyone help? TIS

After you have uncommented the pop-3 line in inetd.conf, restart the INET

It will hang for a minute or two if you do not have names for machines
connecting to it in /etc/hosts or DNS. Linux is paranoid and does a
reverse lookup of any connecting machine. It has to go through DNS
timeout if there is no name for the remote.

Just make sure you have in.telnetd and in.ftpd installed and enabled in
/etc/inetd.conf
********* END OF CUT AND PASTE ***********************************
Ok, the telnet problem has been fixed with the suggestion of David who
provided the solution.
The FTP problem still remains. In my inetd.conf file, both telnet
and ftp services are enabled.
The thing is, how do I verify if in.ftpd is installed? When I run a "ps
a" I dont even see the pid for inetd which on other Unix platforms is
the "parent" for standard tcp/ip services.
Any ideas?

Rene, I´ve reviewed plenty if info, stripped of the redundand info and
quickly put the links which are useful for developers on a page:
http://www.suse.de/~bk/PPPoE-project.html
Through the first link one finds find the RFC for PPPoE, and much other
info on PPPoE.
The second is a refercence to the PPP over Ethernet Mailinglist and the
third is a link to the Ethereal protocol analyzer which is said to have
PPPoE support.
There exist (at least) 2 Linux Client Implementations for PPPoE. One
from
Network TeleSystems(NTS), which (what I´ve heard) is a 100% user mode
piece
which converts asyncronous HDLC-framed PPP frames from the PPP stack to
non HDLC-framed PPPoE frames and communicates with the Kernel over ptys.
The other Client Implementation is made by somebody I´ve a contact to.
He
has also made a PPPoE Server for Linux and his client code likely does
the same as the NTS code, except that it avoids the HDLC layer with a
kernel patch, which is a good thing even if the rest is still
implemented
user space.
Since we have a generic PPP layer in 2.3 now, a native (full-performant)
in-kernel PPPoE layer should be much easyer to do for the new PPP code.
The think I´ve not looked yet too deep is where to put the connection to
the ethernet layer. Comments on this would be very welcome.
I can´t say excatly when this new pppoe-layer will be there because I´m
in terrible need of the two-week vacation I´m going to take now, but I
hope I'll have an PPPoE test environment up and running after it and at
least participate in pppoe testing and development.

you help?
Goal: a linux box that act as a file (Samba) and Internet server for PC
(win95, win98 and Dos 3.11. The Linux box is connected via a modem to an ISP
and is configured as a Firewall (or I think I configure it as a firewall..).
Linux box has an ethernet card as 198.162.0.1, Suse 2.0 is the Linux
currently installed.
PC's are 198.162.0.X with X different from 0 and 1 (Samba works thus...)
Samba works OK
Netscape from the linux box works OK
If from a remote PC (Win98) I use the explorer (network is configure using
TCP/IP address as 198.162.0.1 and DNS is set ON with IP addresses as my
Linux box and two IP addresses provided by my ISP):
The Linux box Diald call the ISP provider,
While the modem is connected I can ping from the remote PC a valid Internet
address
and get response,
I can FTP and download files (Yes it works)
I can browse throught Newsgroup and read news BUT,
I CANNOT display any Web page (I get DNS error)
I cannot send or receive any mail.
I lost already a bunch of my hairs...
What's wrong? My PC setups? My linux box setup?
