Help with PPP connection, 2nd try

Post by Donald Y » Wed, 11 Dec 1996 04:00:00



I have problems connecting to my ISP through Linux. When connecting to my ISP
under DOS/WINDOWS3.1 and OS/2, I am successful, but this is not the case with
Linux. Included is a sample of my chat script and options file as well as
debugging information. The problem seems like the ISP end is not sending
back acknowledgement of my LCP's configure requests. If anyone knows what I am
doing wrong or what I am missing, please help.

Thank you, Don

Example of my chat script.

pppd connect 'chat -v "" ATZ OK ATDT1234567 CONNECT "" ogin: my-login-name
assword:
my-password' debug noipdefault /dev/cua2 19200

Example of my options file.

-detach
modem
lock
crtscts
defaultroute
asyncmap 0
mtu 552
mru 552

Example of my resolv.conf.

domain my.ISP.com
nameserver 1.2.3.4

Debugging information.

Thanks to all who responded, but I have already solved the problem
yesterday. Last night, I've changed my interrupt from 4 (the default for
com 3) to 3 (which is what my USR modem jumpers is set at).

I did this by placing this line '/bin/setserial /dev/cua2 irq 3' in file
/etc/rc.d/rc.local. This sets up the modem to use irq 3.

Hi Donald, it seems to me that your problem is a missconfigured IRQ for
your
modem, all the other configuration looks OK. Grab a copy of the article
called "Guide to PPP/SLIP (long)" posted in comp.os.linux.setup and in
comp.os.linux.networking, it will help you with the modem too.

Bye

Hello Don,

 Everything else seems more or less OK. Delete -detach and the lines
 specifying mtu and mru. Add the following:

ipcp-accept-local
ipcp-accept-remote

 and change to

asyncmap 20A0000

 Looks like your provider's host/terminal-server doesn't respond to
 your pppd's LCP packets. Try the above and post again if the problem
 persists.

1. HELP with script, trying to establish a PPP connection

I wrote this script with some help from a Linux Book. When I ran this
script, I get a "unrecognized command" with a usage dicription for
pppd. I looked over it many time and I could not find any error.

HELP HELP

I'm using pppd version 2.1 patch level 2 (linux 1.0.1)
PPP is compiled in the Kernel
------------------------------------------------------------------------------------------------------------
#!/bin/sh

# A script to establish a dial-up PPP connection

# Shell variable with remote end's IP address
  RMTIP="0.0.0.0"     ( My IP assignes one)

# If PPP link exists, then exit
  /sbin/ifconfig | grep $RMTIP >/dev/null && exit 0

# Other shell variables
# Set LOCIP to "" if your IP adddress is dynamically assingned
LOCIP="0.0.0.0"        ( Assigned by IP )
  PHONE=" phone number of IP "
  DEVICE="/dev/cua0"
  SPEED="38400"
  PPP_USERNAME=" username "
