Hi,
Other than the dhclient-script changes I've hacked for Solaris (which I
still consider too unsanitized for public consumption, but I'll append
'em here as-is) I've had success with dhclient and RoadRunner broadband
cablemodem service in Hawaii since Eric Negaard submitted DLPI patches
for Solaris last year.
Comments about the dhclient-script diffs (just commented-out lines):
+ There's no "-n" option for `arp' thru Solaris 2.6.
+ The `route add default' entries can conflict with the logic that
/etc/init.d/inetinit uses to determine whether or not to launch
in.routed which I run here in conjunction with /etc/gateways and
virtual interfaces to cope with my obscure network topology.
+ I ignore nameservers that the dhcp server provides and don't
modify /etc/resolv.conf.
Ideally, dhclient-script would be conditionalized to handle those
exceptions, but being lazy/busy I've commented-out the lines that
interfere with my configuration. Regardless, the "arp -n ..."
entries are broken -- that's a genuine bug. :-)
Use this information as wish. Thanx!
