Given what you told me the following should work for me:
option host-name = concat("ws-", binary-to-ascii (10,8,leased-address,"-"));
Although I only need the last number in the ipaddress. There is a benifit of having
the entire ip address in the hostname.
Ok. Where can I find info on doing eval expressions and how dhcp privides info to me.
And it looks like I'll be joining another mailing list.
Thanks
