---|---|---|
pppd debug output contains the error message “Could not determine remote IP address.” |
The /etc/ppp/peers/peer-name file does not have an IP address for the peer. The peer does not provide an IP address for itself during link negotiation. |
Supply an IP address for the peer on the pppd command line or in /etc/ppp/peers/peer-name by using the following format: :10.0.0.10 |
pppd debug output shows that CCP data compression has failed and the link is dropped. |
The peers' PPP compression configurations may be in conflict. |
Disable CCP compression by adding the noccp option to /etc/ppp/options on one of the peers. |
