Speed is good when it works. But I am still seeing strange behaviour.
Before even I get into it, I have a question: With the dhcpd.conf that I
have now, do I even need to run the in.tftpd in the system? I stopped
xinetd(in.tftpd) on the TFTP server. Then tried to boot the PXE client.
First the boot stopped at boot: , I reset the machine and it showed me the
menu and upon choosing the iso menu items, it started pulling the iso from
server. So, i want to understand now, whether tftp really needs to be
running on the server.

Thanks in advance.
