Problem with PPP routing under 2.0.0...?

Problem with PPP routing under 2.0.0...?

Post by Don Moo » Tue, 18 Jun 1996 04:00:00



I am running ppp-2.2.0f under Linux kernel version 2.0.0.  Under kernel 1.2.13, everything worked
fine.  However the kernel upgrade seems to have broken something.  The server machine is connected
to the Internet via a LAN (Ethernet).  We have a Cisco 2501 router which acts as the gateway for the
server machine.  The server machine runs the following command when the ppp connection is requested:

exec /usr/sbin/pppd -detach modem passive proxyarp :205.241.224.100

(where 205.241.224.100 is the IP address of the machine calling into the server)

After the two machines connect (the linux box also uses "defaultroute" on the peer side) the
following is the output of "route":

Kernel routing table
Destination     Gateway         Genmask         Flags MSS    Window Use Iface
205.241.224.103 *               255.255.255.255 UH    1500   0        0 ppp0
localnet        *               255.255.255.0   U     1500   0      430 eth0
loopback        *               255.0.0.0       U     3584   0       15 lo
default         c1-e0.ticfin.co *               UG    1500   0       14 eth0

The ONLY thing that changed (as far as I know) with any of the setup when I upgraded the kernel
was the /etc/sysconfig/network-scripts/ifup-lo script (used by redhat during startup).  This
change was suggested in the kernel source under Documentation/Changes.  A line was changed
from "route add -net ${IPADDR}" to "route add -net 127.0.0.0".

--> THE SYMPTOM is that the machine that dials in to the PPP server is unable to see the router
    and/or ping any machine but the PPP server.  It is mentioned in the PPP docs that the
    probable fix for this is to run "proxyarp" on the server side and "defaultroute" on the
    peer side, but I am already doing this!  It worked before, what's broke?

PLEASE HELP!
Thanks in Advance

Ever since I installed Slackware Linux my man pages have never worked.
Whenever I have problems the books always tell me to look at the man
pages!
Here's what happens:

# man ls <ENTER>
Formatting page, please wait...
sh: /usr/bin/gtbl: no such file or directory
sh: /usr/bin/groff: no such file or directory

I used
# find / -name gtbl -print
and also
# find / -name groff -print
but those files are nowhere to be found.

Any help appreciated. Thanks.

p.s. I figured it out myself, fancy that.  In case anyone cares even in the least, the problem was
that when I compiled the 2.0.0 kernel, I forgot to turn on the IP Forwarding/Gatewaying option.

 You need to install the groof package off your cd...
  Think it's in the ap diskset, not sure.......

It would probably work, once you installed the needed programs.
