Hi all,

I am facing a problem in resolving the tftp alias name using dhcp.

I have the below configuration in dhcpd.conf:
option domain-name "ab.lab";
option domain-name-servers,;
option tftp-server-name "proj-1";

nslookup of proj-1:
>nslookup proj-1

Non-authoritative answer:
proj-1.ab.lab        canonical name = cc675.ab.lab
Name:   cc675.ab.lab

But the linux board booting got failed with error "Command tftp failed, with error unknown host proj-1.ab.lab."

But when I give the "option tftp-server-name" in dhcp specifying the direct ip address, it is booting successfully and everything is fine.

Could you please guide me whether I missed anything configuring in dhcpd.conf file or did I do anything wrong in configuration?
