OpenBSD cannot get an IP with DHCP


Recommended Posts

I have installed OpenBSD on VirtualBox this evening, everything seems fine, except the networking.

I have enabled networking in VirtualBox to use "Host interface" as network connection of the virtual machine. This configuration does work for Windows Vista on another virtual machine. I then, in OpenBSD, checked /etc/hostname.em0, there is only a word dhcp, which suppose to make OpenBSD to get a private IP from DHCP server. I also checked /etc/resolv.conf, I leave a line, 192.168.1.1, which points to the router in my home. I then ifconfig em0 down and then ifconfig em0 up. However, after these steps, OpenBSD still cannot find host 192.168.1.1.

I wonder if it is problem of OpenBSD or I missed something? I tried to use static IP for my OpenBSD too, but that didn't help.

Thanks for any input.

I know in Linux just doing a ifconfig <interface> up/down does not reinitiate a request to the DHCP server for an IP address. It either takes the interface down or up.

Using some sort of DHCP client is what gets the IP address from a dhcp server, as someone above has just mentioned. try outputting the results of ifconfig. Do you see a private IP address listed there for that interface?

This afternoon I tried dhclient, DHCPDISCOVER still couldn't get a private IP from my router, perhaps there are some problems with the configuration of utility?

I also made a search on Google, and I found this:

http://www.bsdguides.org/guides/freebsd/ne...ure_network.php

The command ifconfig <IP> netmask <subnet mask> and route add default <gateway IP> helped me to get replies from ping google.com. The network is fine now, but it is using static IP (I want it to use DHCP).

Perhaps I need to spend sometime on dhclient and /etc/dhclient.conf.

Thanks everyone.

I think those two sub-forums would get posts categorized to be a lot more helpful in topic management.

    • Microsoft is removing legacy drivers from Windows Update by Usama Jawad Last month, we learned that Microsoft is making major changes to the development of hardware drivers in Windows. This included the retirement of Windows Metadata and Internet Services (WMIS), along with the process for pre-production driver signing. Now, the Redmond tech firm has informed partners that it will be getting rid of old drivers in Windows Update. In what is being described as a "strategic" move to improve the security posture and compatibility of Windows, Microsoft has announced that it will be performing a cleanup of legacy drivers that are still being delivered through Windows Update. Right now, the first phase only targets drivers that already have modern replacements present in Windows Update. As a part of its cleanup process, Microsoft will expire legacy drivers so that it is not offered to any system. This expiration involves removing audience segments in the Hardware Development Center. Partners can still republish a driver that was deemed as legacy by Microsoft, but the firm may require a justification. Once the Redmond tech giant completes its first phase of this cleanup, it will give partners a six-month grace period to share any concerns. However, if no concerns are brought forward, the drivers will be permanently eradicated from Windows Update. Microsoft has emphasized that this will be a regular activity moving forward and while the current phase only targets legacy drivers with newer replacements, the next phases may expand the scope of this cleanup and remove other drivers too. That said, each time the company takes a step in this direction, it will inform partners so that there is transparency between both parties. Microsoft believes that this move will help improve the security posture of Windows and ensure that an optimized set of drivers is offered to end-users. The firm has asked partners to review their drivers in Hardware Program so that there are no unexpected surprises during this cleanup process.
    • No idea, but I had a client the other week that lost the entire drive to it. I suggested relying on the Samsung T7's instead. The Sandisk Extreme's had reliability issues too.
    • I use it every day so personally yes I need it, or rather I want it. I use OpenShell though, not the garbage modern Start Menu. I just counted and at the moment I have a total of 92 program shortcuts organized into six folders almost exactly the way I did back in Windows 95. I can get to any program I want to run very quickly. I never use Search to find or run programs.
    • I do miss the Apps view from Windows 8.1 Update.
    • I use the search function and little else since Windows 11 (but there are times where Saved Searches take precedence since the search feature on the Start menu is worse than before). I use other features in previous releases.
