PPP connects, but then nothing...

Post by Broc Stirto » Tue, 24 Feb 1998 04:00:00



Hello all-
        I am having a problem connecting my linux box to our school
server via
 TIA PPP emulator (I have read the SLIP/PPP emulator HOWTO).  I have set
up
PPP on several machines for ISP who use real PPP, but this emulator has
me
stuck.  All computers dialing in are supposed to use 192.0.2.1 for their
IP
(static, not assigned in connection negotiations).  I am connecting with
minicom (login, start remote ppp, exit w/out reset) and starting pppd on
command line.  My /etc/ppp/options has the following:

-d
-detach
modem
lock
crtscts
defaultroute
asyncmap 0    
192.0.2.1:192.92.253.11
----------

After connecting ifconfig is as follows:

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Bcast:127.255.255.255  Mask:255.0.0.0
          UP BROADCAST LOOPBACK RUNNING  MTU:3584  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0
          TX packets:0 errors:0 dropped:0 overruns:0

ppp0      Link encap:Point-Point Protocol
          inet addr:192.0.2.1  P-t-P:192.91.253.11  Mask:255.255.255.0
          UP POINTOPOINT RUNNING  MTU:1500  Metric:1
          RX packets:6 errors:0 dropped:0 overruns:0
          TX packets:5 errors:0 dropped:0 overruns:0

route -n gives:

Sorry for the length of the post, but can anyone tell me why I can't
ping
anything (even 192.92.253.11) when the link appears to be up (the line
is
still connected, I can hear it disconnect when I kill pppd).  tcpdump
during
ping attempts gives:
