by I am having tough problems trying to get my LOCAL network at home and
the PPP based network (to the world) working TOGETHER...
^^^^^^^^^^^^^^^^
Actually the local network never worked.
The IP address of this LINUX machine for __local__ network is DIFFERENT
from the IP address this LINUX machine assumes when its hooked up by PPP.
I had recompiled the kernel to support, Soundblaster and Ethernet.
The Soundblaster support works great -- (proof that I didn't*up...
please note the dmesg o/p at end of this article -- thanks).
The new kernel detects the NE2000 compatible cards just fine.
----- DETAILS ----
I have a linux system as my Mail station (uses regular Sendmail & SMTP).
I am also using it for LINUX development (linux based sound-applications).
I have another machine for Win95. Both these machines have ethernet cards.
Both the machine's OS recognized the ethernet cards. (Linux output at end)
I use PPP to connect to the world (thru LINUX).
But I need the ethernet connection between the LINUX machine and the Win95
machine.
The PPP connection (FROM LINUX) connects me to the domain
"*.remote.princeton.edu". (128.112.67.*)
The Win95 machine is used to hook into the WindowsNetBeui network at WORK
so, I have obtained a UNIQUE IP address for it. I also obtained another
IP address for the LINUX machine (so that it does not clash with other's
IP addresses). The intranet at work will never be directly connected to
the internet (security purposes).
The domain at work is "*.lipper.com" (198.20.186.*)
I have just one monitor and keyboard for both machines. I prefer using
the "telnet" from Win95 to get into the linux machine (rather than having
to manually pull out the video, mouse and keybd connections from one and
plug it into the other every time I want to switch).
I did the following (after reading the /usr/doc/faq/howto and the FAQs)...
But if I placed the following lines in /etc/rc.d/rc.inet1, NEITHER the
ethernet worked, NOR did the PPP network (when I started up PPP). But when I
shut down the machine (after commenting out the code in /etc/rc.d/rc.inet1)
and restarted the machine, the PPP network works fine.
Also, the "route" command (as root) just hangs if I have the local network
also "ON" using the following lines from /etc/rc.d/rc.inet1 ....
(please see the system files on the next 30 lines)...
I would like the LINUX machine to respond via eth0, when the Win95 machine
starts looking for the "198.20.186.60" address (which is the address assigned
to the LINUX m/c's eth0 PORT). That is the only feature of the local net
I am looking for. (i.e., being able to telnet and FTP from Win95 to LINUX).
What am I doing wrong? Can someone help me get my local net up and running?
If the above setup is not possible could someone help me with using the
STANDARD localnet IP addresses (127.0.0.* -- Am I right?)
