Per the manual, I've added this stub:
root@freeradius:/etc/zentyal/stubs/network# cat dhclient.conf.mas
<%args>
$hostname
</%args>
send host-name = "<% $hostname %>";
option rfc3442-classless-static-routes code 121 = array of unsigned integer 8;
request subnet-mask, broadcast-address, time-offset, routers,
domain-name, domain-name-servers, domain-search, host-name,
netbios-name-servers, netbios-scope, interface-mtu,
rfc3442-classless-static-routes, ntp-servers;
timeout 15;
Which right after boot, it succeeds for a hot minute... I can type "route" and see the routes. Shortly after that however, those routes are cleared and only the default gateway remains. Is there another script that is clearing these routes?
