| Issue |
We are running PPP through a satellite hop and
it introduces significant delays. We are trying
to find the QNX timeouts associated with the PPP negotiation. Are these user adjustable?
|
| Solution |
The default timeouts for QNX4.25 are:
1. For line control negotiations: a message is sent out for restart every 3 seconds up to 10 attempts.
2. For IP control negotiations: a message is sent out for restart every 3 seconds up to 10 attempts.
The defaults can be changed in QNX4.25. These can be changed when pppd is started, simply add the following options to the command line.
To change the restart and maximum number of attempts for line control negotiations:
pppd lcp-restart=<some_value> lcp-max-configure=<some_value>
To change the restart and the maximum number of attempts for the IP control negotiations:
pppd ipcp-rstart=<some_value> ipcp-max-configure=<some_value>
