support setting net.dns.search

[GoogleCodeExporter]

Hi,

In the same way that we can configure to set net.dns1 it would also be nice
if we can use the dhcp pushed search-domain to set net.dns.search.

This can be done in a up/down script but it would be neater to not have to
write one just for this.

Keep up the good work,

Daire

please tell more about the up/down script you mentioned - is it possible to 
auto trigger it upon connect/disconnect from a VPN ?

Setting property net.dns.search to the local domain does allow looking up 
hostnames without the domain suffix. However, when I added
setprop net.dns.search "${new_domain_name}"
to the dhcpcd hook script it wouldn't work - it wouldn't add the property.
At the same time, when I added
echo "${new_domain_name}" > /data/local/domain_name
to the end of the same script, it worked correctly...
Any idea what's going on?

Just an update - reply to my own comment.
Adding the property wouldn't work because of insufficient rights - dhcpcd runs 
as unprivileged user dhcp. For some reason I couldn't get
su setprop net.dns.search "${new_domain_name}"
to work either - the su request would be denied without showing the 
Superuser.apk confirmation window.
Any ideas? :)

try:
su -c 'setprop net.dns.search "${new_domain_name}"'

Thanks Friedrich,
I made a mistake in the comment - that's what I'm trying.
su -c 'setprop net.dns.search "${new_domain_name}"'
in the dhcpcd hook is always denied without bringing up the Superuser window...
