I used the following /etc/ppp/options
to connect to CISCO terminal
server PPP line.
crtscts # enable hardware flow control modem # modem control line noipdefault # remote PPP server must supply your IP address. # if the remote host doesn't send your IP during IPCP # negotiation , remove this option passive # wait for LCP packets domain ppp.foo.com # put your domain name here :<remote_ip> # put the IP of remote PPP host here # it will be used to route packets via PPP link # if you didn't specified the noipdefault option # change this line to <local_ip>:<remote_ip> defaultroute # put this if you want that PPP server will be your # default router
To connect:
/usr/src/usr.sbin/pppd.new/pppd /dev/tty01 19200( put the appropriate speed and device name )
Now your computer is connected with PPP. If the connection fails for some
reasons you can add the "debug" option to the /etc/ppp/options
file
and check messages on the console to track the problem
Following /etc/ppp/pppup
script will make all 3 stages automatically:
#!/bin/sh ps ax |grep pppd |grep -v grep pid=`ps ax |grep pppd |grep -v grep|awk '{print $1;}'` if [ "X${pid}" != "X" ] ; then echo 'killing pppd, PID=' ${pid} kill ${pid} fi ps ax |grep kermit |grep -v grep pid=`ps ax |grep kermit |grep -v grep|awk '{print $1;}'` if [ "X${pid}" != "X" ] ; then echo 'killing kermit, PID=' ${pid} kill -9 ${pid} fi ifconfig ppp0 down ifconfig ppp0 delete kermit -y /etc/ppp/kermit.dial pppd /dev/tty01 19200
/etc/ppp/kermit.dial
is kermit script that dials and makes all
necessary authorization on the remote host.
( Example of such script is attached to the end of this document )
Use the following /etc/ppp/pppdown
script to disconnect the PPP line:
#!/bin/sh pid=`ps ax |grep pppd |grep -v grep|awk '{print $1;}'` if [ X${pid} != "X" ] ; then echo 'killing pppd, PID=' ${pid} kill -TERM ${pid} fi ps ax |grep kermit |grep -v grep pid=`ps ax |grep kermit |grep -v grep|awk '{print $1;}'` if [ "X${pid}" != "X" ] ; then echo 'killing kermit, PID=' ${pid} kill -9 ${pid} fi /sbin/ifconfig ppp0 down /sbin/ifconfig ppp0 delete kermit -y /etc/ppp/kermit.hup /etc/ppp/ppptest
Check if PPP is still running (/usr/etc/ppp/ppptest
):
#!/bin/sh pid=`ps ax| grep pppd |grep -v grep|awk '{print $1;}'` if [ X${pid} != "X" ] ; then echo 'pppd running: PID=' ${pid-NONE} else echo 'No pppd running.' fi set -x netstat -n -I ppp0 ifconfig ppp0
Hangs up modem line (/etc/ppp/kermit.hup
):
set line /dev/tty01 ; put your modem device here set speed 19200 set file type binary set file names literal set win 8 set rec pack 1024 set send pack 1024 set block 3 set term bytesize 8 set command bytesize 8 set flow none pau 1 out +++ inp 5 OK out ATH0\13 echo \13 exit
Here is an alternate method using chat
instead of
kermit
.

The following two files are sufficient to accomplish a pppd connection.
/etc/ppp/options
:
/dev/cuaa1 115200 crtscts # enable hardware flow control modem # modem control line connect "/usr/bin/chat -f /etc/ppp/login.chat.script" noipdefault # remote PPP server must supply your IP address. # if the remote host doesn't send your IP during # IPCP negotiation, remove this option passive # wait for LCP packets domain <your.domain> # put your domain name here : # put the IP of remote PPP host here # it will be used to route packets via PPP link # if you didn't specified the noipdefault option # change this line to <local_ip>:<remote_ip> defaultroute # put this if you want that PPP server will be # your default router
/etc/ppp/login.chat.script
:
(This should actually go into a single line.)
ABORT BUSY ABORT 'NO CARRIER' "" AT OK ATDT<phone.number> CONNECT "" TIMEOUT 10 ogin:-\\r-ogin: <login-id> TIMEOUT 5 sword: <password>
Once these are installed and modified correctly, all you need to do is
pppd
.
