DHCP with several servers

trovatou · 05-10-2007, 03:29 AM

Hello,

How are you?? I hope fine...

My question is that I have 16 linux computers that are connected to a linux server and they use DHCP to obtain their IPs. The problem is that now I want to use another server for this "cluster", and I want that the clients can also ask for their IPs to this new server, so I want to configure this DHCP service with several servers, but I dont know how.

Can someone help me???

Thank you.....

you're replacing one dhcp server with another? just stop dhcp on the current one and copy the leases across and start the new one. am i missing something? clients don't ask dhcp servers for leases, they just broadcast and hope someone responds, they don't care who normally.

Thank you for your answer, but may be I haven't specify enogh.

I need to use both servers at the same time, because I want to
develop this servers to colaborate each other to balance the work.

May be now, you can help me better.....

Thank you again...

dhcp doesn't work well in an load balanced environment. whilst it's nice to have in theory, it goes bad very quickly... you could use a heartbeat across two boxes so a slave starts dhcpd if the master isn't available etc... also the load on a dhcp server is typically small, unless you're an isp or something...
