seems you allow spaces, commas, ...
is it intentional.. spaces are fine as linux will add a search [list of domains] directive into /etc/resolv.conf... but for windows box this has no use...
but we have probably some side effects with that into dhcpd logs:
2008:12:02-13:29:05 (none) dhcpd: if rog.dynsrv.net resalys.com office.dotwiz.com dotwiz.com office.resalys.com hostflow.com IN A rrset doesn't exist add rog.dynsrv.net resalys.com office.dotwiz.com dotwiz.com office.resalys.com hostflow.com 43200 IN A 192.168.1.194: timed out.
where rog is a windows box...
can this cause some trouble (timeout) with dhcpd process ?
also what about other chars like commas ? this has no effect so probably need to be forbidden...
so you may need to add some "if" statement into dhcpd.conf to have multi domains available only for the linux boxes (and other unix like boxes=not windows)..
what about a domain list box ? with priority and the top priority domain will be the main domain for windows boxes...
but please do not remove possibility to have multi domain search !!!
thx
