dhcp-server

In our office the setup is like we have a UBUNTU server with DHCP Server connected to all the PCS via 24 port and 8 port DLink switches. How can I find all the PCS(with client name, ip and mac address)in the network??

When I do "vi /var/lib/dhcp3/dhcpd.leases", I get all the ip addresses for the switches.

I have used "arp-scan --interface=eth0 --localnet" to get all the IPs and MAC Addresses in my local network. I couldn't find any option to diplay client name.

Also I would like to assign particular IP for a particular PC. I have done the changes in the dhcp.conf file but it is not working as they are not directly connected to DHCP-server(DLink switches in between). How can I assign IPs for PCs in this kind of setup.

Thanks in advance
