OK, so you don't need to send a host-name to the DHCP server in order to get a lease. > After that d-i notices I still don't have a hostname, so it offers 'debian' > as default (which I change), after which d-i happily continues the > installation _without_ DHCP being tried again. The default hostname in the prompt should be the one returned via DHCP, IMHO. I may open a separate bug report to track that issue. > (The domainname is set correctly to 'fjphome.nl' as offered by the DHCP > server.) > > So, what I would like to see is 'Write "send host-name <host-name>"' added to > dhclient.conf either at (1) or at (2) as indicated in code below (using > hostname as host-name ;-) I disagree. If you don't need a host-name to get a lease before reboot then you shouldn't need a host-name to get a lease after reboot. If a host-name isn't needed then no "send host-name" line should be written to dhclient.conf. The installer should not configure the system to request a lease in a different way from the way that was tried and proved successful. > In fact, I'm not sure that the 'else' branch to the first 'if' really adds > something: why would a DHCP-request with send host-name succeed if the first > try without one fails? Some DHCP servers demand that a magic string be sent as the host-name. > I agree that host-name can be different from hostname.

Sending a host-name could result in failure to obtain a lease. Also, sending a host-name requires asking the user for a host-name prior to attempting to obtain a lease. It is better to skip that step if a lease can be obtained without asking the user anything. > I've pasted an example of the lease I get at the bottom of this message. > > The lease I get returned _after_ (manually) adding 'send host-name > "<host-name>"' is exactly the same (I think this indicates that the server > has accepted the proposed host-name), but having the client send it means the > DHCP-server is able to dynamically add the host-name in my DNS server (and so > enabling me to ping <host-name>.fjphome.nl from other boxes in the network). Shouldn't the server be able to add your hostname to DNS without your client having to request this by requesting the hostname? Sounds like a peculiarity of your server. In any case this is something that you can configure locally. I don't think that the installer should configure dhclient this way by default, for the reasons given above. I'd like to mark this "wontfix". -- Thomas -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
