Can't establish dial-up ppp connection to my ISP. I am using RedHat Linux
5.1. The modems connect, login and password sequence is ok. I have
previously verified via minicom that the ISP host is sending the "garbage"
string to indicate the beginning of ppp.
But when pppd begins, my box sends repeated lcp-confreq messages without
receiving any. After about 90 seconds, the modem hangs up. The provider
indicates that he is receiving and sending lcp messages. Our side doesn't
see the replies.
Our ppp options file includes:
/dev/cua0
nodetach
modem
crtscts
lock
mru 542
defaultroute
noipdefault
ipcp-accept-local
ipcp-accept-remote
lcp-echo-interval 5
lcp-max-configure 50
debug
kdebug 25
Have tried many variations in options.
>From the log - typical attempt except for lines 7 and 10 (a rare receive).
The other attempts resemble this without lines 7 and 10.
