2.1 Troubleshooting ISP Connection

If you are getting the connection and getting the local IP address and Remote IP address from KPPP dialer but you are not able to do ping on a remote host like 'ping www.yahoo.com' then do:

bash$ su - root
# ifconfig

See the listing above and temporarily disable other interfaces like eth0, eth1
# ifconfig eth0 down
# ifconfig eth1 down
# ifconfig eth2 down

# ifconfig
This should list only ppp0 and lo

bash$ ping www.yahoo.com
If connection is okay, then do:
bash$ su - root
# ifconfig eth0 up
# ifconfig eth1 up
# ifconfig eth2 up
# ifconfig

If you still have problems then refer to the KPPP user guides and FAQs as below:

$ rpm -ql kdenetwork-ppp
$ cd /usr/share/doc/HTML/en/kppp
$ docbook2html kppp-faq.docbook 1> kppp-faq.html
