Subject:   tcpdump on a dial-in PPP connection ?
Message-ID:  <H000057c016b6bb7@MHS>
next in thread | raw e-mail | index | archive | help 
     Hello,
     
     I would like to see what packets are exchanged on a dialin PPP link
     
     I manage my modem with mgetty (as indicated in the handbook)  - on an 
     incoming call, all goes well : ppp is established, ....
     
     my setup is a 225-Release with a fairly recent user-ppp 
     (ppp-980227_src.tgz).
     
     BUT ....
     
     I can't get tcpdump working on tun0
     
     I suspect it must be configuered in/etc/ppp/ppp.linkup
     I've added :
     #
     MYADDR:
      delete 0
      add 0 0 HISADDR
      !bg tcpdump -l -i tun0 >> /tmp/tun0
      
     but no way, the /tmp/tun0 doesn't exist.
     
     Any ideas ?
     
        TIA
     
        TfH
