Default DHCP inet problem

Hello this is my small problem

i have my : /etc/hostname.bce0 = dhcp
after i reboot server it takes all the information needed form the DHCP

everything works fine but when i want to reassign the IP

#ifconfig bce inet 192.168.1.233 netmask 255.255.255.0

it takes forever to log in thru ssh and is impossible to resolve anything nslookup dig, after i change ip back to the original one everything goes back to normal

if i try to modify with #vi /etc/hostname.bce0 from dhcp to inet 192.168.1.233 netask 255.255.255.0 NONE and reboot same story

so i am lost

I can only assume that "bce" above is a typo. Given other information presented, this should be "bce0".

It also is not clear from the information provided whether 192.168.1.233 had been the IP address provided by your ISP's DHCP server, or how you decided it use this particular private address. My guess is that this had been previously supplied by DHCP. If so, this may account for the following:

...which is frequently the tell-tale sign that DNS is confused. Section 8.22 of the FAQ covers this situation in more detail.

At this point, we simply don't have enough information to figure out what is going on. If you can help clarify the configuration, we may be able to help solve it.

thanks ocicat for the reply

yes its bce0 i misstyped here

i have one static ip xx.xx.xx.xx ... and my isp deltacom need to point it to a specific local ip so i picked 192.168.1.233

the router dhcp gives ip's from 192.168.1.2 up to 192.168.1.229 and ISP does not provide username and password to configure router

i installed openbsd and left settings to dhcp so after installation i was assigned one ip and every ip dhcp assign openbsd go smooth but when i want to set ip to 192.168.1.233 it doesnt resolve anything ssh takes forever

there is no proxy or sendmail

the computer running openbsd 4.7 is a fresh installation that has been updated, before the update it had same problem

i am connecting to it from inside the lan from a machine running windows 2003 server standard, and i am using putty

thanks

Provide a diagram of your configuration -- something similar to:
Code:
                             192.168.1.11
                                  /
                  192.168.1.10   /  +-- 192.168.1.12
                              \ /   /
            ISP ----------  router ----------------------- 192.168.1.14
                      DHCP      \ \
                                 \  +--192.168.1.13
                                  \
                            192.168.1.15
If it is easier to make something offline & attach, do so. Clearly identify all interfaces complete with their IP addresses.

The term is "switch".

What is the netmask implemented/assumed by the switch?

You chose 192.168.1.233 because you felt this was outside the range provided by the router's DHCP server? Does the switch's documentation state that it will route packets not in the defined range?

So, can all internal hosts succesfully ping each other by IP address?

Does the documentation state that the switch will handle addresses outside of the defined DHCP range?

Identify the OpenBSD system in your diagram, or is it external to your home network?
