ppp doesn't work...chat script is the problem?

Post by Norman Leitma » Fri, 21 Nov 1997 04:00:00

I'm running Redhat 4.2 and trying to dial my ISP and connect using ppp.  

I added kdebug 25 to the /etc/ppp/options file, so that I get an output log of all of the characters
going through the serial port.  I see that I make the connection successfully, and data gets
transferred both ways.  At some point, I get "ppp_tty_read: no data (EAGAIN)".  After several of
these (these are separated by some transmits), I get "IPCP: timeout sending Config-Requests".  When
I do an ifconfig, I dont see the ppp0 entry, and if I try to do an ftp, I get "network unreachable"

I understand that after the physical connection is made, the LCP (link layer protocol is set up),
and then the IPCP (ip protocol) is set up.  I never get the LCP messages.  

I believe that my ISP is waiting for me to send more information after I send my login and password.  
Under Windows, I use a pop-up terminal.  After entering the login and password, I must close the
pop-up window, which then establishes the connection and starts the ppp server at the ISP.  I don't
know how to do the equivalent operation using the chat script.  How do I start the ppp server at the  
ISP ("close the pop-up terminal") after sending the login and password?  In my log file I see that
everything is correct up to the point I finish entering these...but I never get past this.

Thanks in advance for your help.

1. Can't Get PPP Working - Chat (ppp-on) script won't dial

While I can run CSLIP using a DIP script with no provblem, I haven't been
able to get ppp to work. I'm using a ppp-on script adapted for my host
site, but it just falls through to the error message (no lockfile problem).
The ppp driver is in my kernel; I'm on kerneo 1.1.18, and using ppp 2.1.2a.
The chat script won't get my modem dialing. Modem as the device does not
work, neither does cua1 (which I use for SLIP). I will be glad to supply
any additional information needed. And yes, ppp IS in /etc/ppp, and
installed properly, as far as I can tell. Thanks for any help. I have RTFM.
