Problem setting up PPP in Linux machine

[madhu violet csa iisc ernet in]

 hi,

 iam trying to set up my system with PPP support.

 its  a Linux  Pentium i586 machine.

 i have compiled in PPP support into kernel as 

 a loadable module. and i checked the versions

 to be appropriate.

 i have some necessary scripts ready like

   /etc/ppp/options
   /etc/ppp/scripts/ppp-on
   /etc/ppp/scripts/ppp-on-dialer
   /etc/ppp/scripts/ppp-off

 i have a 33.6k bps/sec modem connected to my

 serial port /dev/ttyS1 as a link from /dev/modem.

 it is not a WINMODEM. 

 the log file shows 

    Aug 27 19:06:29 localhost kernel: CSLIP: code copyright 1989 Regents
                                         of the University of California 
    Aug 27 19:06:29 localhost kernel: PPP: version 2.3.7 (demand dialling) 
    Aug 27 19:06:29 localhost kernel: PPP line discipline registered.

  my PPP server needs me to run PPPD first on the server

  before logging in as user.

  can anybody help me why iam not able to connect to my server

  even when i run  ppp-on script , which as usual runs pppd on my system

  along with chat and with appropriate options.

  if i run pppd alone, the log shows

  Aug 28 14:32:01 localhost modprobe: can't locate module char-major-108
  Aug 28 14:32:01 localhost pppd[2214]: pppd 2.3.10 started by madhu, uid 503
  Aug 28 14:32:01 localhost pppd[2214]: Using interface ppp0
  Aug 28 14:32:01 localhost pppd[2214]: Connect: ppp0 <--> /dev/pts/3
  Aug 28 14:32:31 localhost pppd[2214]: LCP:timeout sending Config-Requests 
  Aug 28 14:32:31 localhost pppd[2214]: Connection terminated.
  Aug 28 14:32:31 localhost pppd[2214]: Exit. 


  and when i run ppp-on script, the log looks like

  Aug 29 00:12:28 localhost modprobe: can't locate module char-major-108
  Aug 29 00:12:28 localhost pppd[796]: pppd 2.3.10 started by madhu, uid0
