 Problem with hp-ux 10.2 and dhcp (client) We have a requirement to move some computers between subnets and wanted to turn on dhcp on. In doing so the initial configuration will work if we put the proper gateway into the netconf file and the dhcp stays enabled after boot. The problem is when we move to another subnet the DHCP server is either not reached or response does not get back and the HP assumes to stay on the last configuration. The network is started and is misconfigured and proceeds to perform a one hour boot. Was there problems in HP implementation for a mobile device (moving from subnet to subnet) from working properly? Do we have to do something to facilitate this to work properly like releasing our lease?      |

| Re: Problem with hp-ux 10.2 and dhcp (client) Do you have a dhcp server on every subnet? Normally dhcp requests are not forwarded by routers so you can not reach the dhcp server on another subnet. You don't want that anyway because you would get the wrong settings. So get a dhcp server on every subnet and beside the ip number also configure it to set the default gateway,netmask and dns servers.

| Re: Problem with hp-ux 10.2 and dhcp (client) AS I was going through looking at the packet on a sniffer I found that if I did not release the dhcp lease the expected packets when across....dhcp request....the request was nak'd.....a dhcp discovery .....and an offer came back....but when time to make a request it changes the transaction id from the offer. It would seem if the dhcp server is validating the request to the offer it will puke on the request due to the new transaction id.
