How to Diagnose and Fix Communications Problems

Communications problems occur when the two peers cannot successfully establish a link. Sometimes these problems are actually negotiation problems that are caused by incorrectly configured chat scripts. The following procedure shows you how to clear communication problems. For clearing negotiation problems that are caused by a faulty chat script, see Table 7–5.

1. Become an administrator on the local machine.

   For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.2 .

2. Call the peer.
3. Call the remote peer. Then enable debugging features.

   % pppd debug call peer-name

   You might need to obtain debugging information from the peer in order to fix certain communications problems.

4. Check the resulting logs for communication problems. For more information, refer to General Communications Problems That Affect PPP.
