Re: PPP Configuration: Getting Hooked Up to my ISP

["M. Fong" <mjf@jps.net>]

Status: Stage 2:  Further along, running into DNS issues

Thanks for the suggestions thus far:
  I had a shell script which didn't have the correct 'executable'
permissions. Something like rw-rw-rw instead of chmod 777
/etc/ppp/<whatever_script>.

Here is how far I have progressed:
1. Executing pppd now dials out (I never got this far in Stage 1 becaues a
script file did not have execute
    permissions hence it was unable to call chat())
2. Logging into the ISP successfully
3. PAP authentication works fine
4. I can ping the ISP's gateway machine.

<< BRICK WALL>>
5. I cannot ping anything that is not localhost or the gateway (see below)
    Ex. 'ping sunsite.unc.edu'

6. DNS configuration does not seem configured properly. I am inferring this
by
    comparing my output of ifconfig() and route () with the output example
in the
    PPP-HOWTO document.
