Hi Bernard,
apparently, Mandriva is now using a similar approach to deal with static routes as Fedora and Rad
Hat. It now uses the same command to reload the route
("/etc/sysconfig/network-scripts/ifup-routes), but the routes are now stored in a file named
<interface>.route, in "/etc/sysconfig/network-scripts/".
I changed the function 'add_multicast_route' from Ganglia's 'edit_ganglia_conf'
file but, before to commit them, I have some issues to discuss:
1) The <interface>.route file that will keep a record of the routes doesn't exists by default
so we can just `echo $route_string >> $static_route_file`. Although that works without
problems, the route string I'm using is 'ADDRESS0=224.0.0.0 NETMASK0=240.0.0.0', and the
"0" that comes after 'ADDRESS' and 'NETMASK' indicates the id of the route. I a special
case where there's already a file with one route configured, the command would replace that route.
2) Ganglia GMOND is restarted *before* the changes in the route, while Ganglia
GMETAD is restarted *after*. To have Ganglia operational, I have to restart
GMOND once Step 3 is finished. Would be possible to incorporate a restart
command for GMOND after the reload of the routes?
You can find the modified version of 'add_multicast_route' below.
Thanks,
Fernando
PS: should I open a ticket for this in the new system?
