description des différents paramètres
[edit]
AllowNoInt
cette option permet de laisser olsr en standy by lorsqu il n y a plus d interfaces sans planter. pratique lors d' un /etc/init.d/networking restart ou d'une reconfiguraztion de carte radio.
[edit]
ClearScreen
Tables are now only printed if changes occur, so there are no longer any periodical output when using a debuglevel >0. A "heartbeat" is now printed to STDOUT(if it is a terminal) in the form of a rotating line to show that olsrd is actually operating. Adding "ClearScreen yes" to the configuration file clears the screen each time before the debug output shows updated information. This makes the debug output easier to read in many cases. "ClearScreen no" is the default, if no "ClearScreen" directive is given in the configuration file.
[edit]
PollingRate
This option sets the interval, in seconds, that the olsrd event scheduler should be set to poll. A setting of 0.2 will set olsrd to poll for events every 0.2 seconds. Defaults to 0.1.
[edit]
TcRedundancy
La TC redundancy indique combien d'information de voisin devrait être introduite des messages de TC les valeurs que possibles sont : 0 - envoyez seulement les sélecteurs de MPR 1 - envoyez les sélecteurs MPR et les MPRs 2 - envoient a tous les voisins # par default la valeur est a 0 MultiPointRelais est une des autres 'optimization' notoires ; disponible dans RFC3626... mettez la valeur a off en mettant la valeur de redondance a 2
