Once the /etc/ppp/chap-secrets has been written to by the IP, the original pernissions can be restored. The problem however may recurr at another call in site. When I was using ATT.net , all was well for dialout from home. But when I tried an ATT.net dialup while visiting elsewhere, the chap-secrets problem was encountered. So it seems that different callup numbers on the same Some.NET may have different security protocols.
