dhcp

Hi everyone, I'm doing a pet project where I'm designing the topology of what I'm going to implement on my physical server when I'll buy it. So, right now, I'm working in VMware Fusion, just to play with it and understand how things can be configured. But before exploring the topic, I'll give...

I've run a simple experiment on FreeBSD 14.0 and the results are quite unexpected to me. Could you explain these results to me? Warning! The experiment MUST be run from console. Do not try to reproduce it over SSH as it will make the host inaccessible! Console log, with comments: # killall...

Hello. I'm pretty new to FreeBSD after having using GNU/Linux for more than a decade. I've installed FreeBSD 14.0 (MATE desktop) on an rather old Samsung AMD A6-3420m apu with radeon hd graphics (AMD Sumo 512 MB) and 4GB ram. Everything went fine, but after booting one time, only to discover...

Hi, I have a FreeBSD server running 14.0. It's primary network interface receives public IP and default route via dhclient. Sometimes after fiddling with static routes in fib 1 and adding these to rc.conf I need to run: service netif restart service routing restart This however removes the...

I currently use FreeBSD on a laptop and I need to connect to different wireless network, some blocked external DNS server somehow, so I was wonder if there is a way to change my DNS server with DHCP assigning. I have to manually change my resolv.conf to get that to work. Any suggestion would...

Hello everyone, I recently installed FreeBSD 13.1-RELEASE on another computer. The installation went fine, except that no internet connection could be established, although my network card was recognized and attached to the alc driver and it having a working network cable attached to it. I know...

I'm trying to setup some bhyve guests for the first time on my 13.0-RELEASE system but the guests were unable to obtain IP addresses from the DHCP server on my router unless I disabled ipfw. It appears that ipfw was blocking the responses from the DHCP server. Google searches didn't come up...

Hi all, I'm trying to comprehend how FreeBSD updates /etc/resolv.conf. Upon boot my interface gets an IP from the DHCP server, but resolv.conf remains missing. Running dhclient vxm0 gets an IP, but does not populate the various kenv variables that /etc/rc.d/resolv uses. Does anyone know what...

I believe I may have misconfigured something, but I am not sure what. I am connecting to a hotel AP with a captured portal at this time. I was attempting to request a new dhcp lease (at this point I still had a connection - able to ping google.com). I did so by attempting to run dhclient on my...

My Internet wasn't working properly, and I wasn't able to ping my router. Some Internet sites worked, while others didn't. Used a live Linux CD, and the Internet was fine, and I could ping my router from it. That showed that the problem wasn't my router or the Ethernet cable. It turns out that...

While trying to understand if it is possible for me to have more than one IP address in my computer (I don't even have one that is static at the moment), I found the discussions on this thread which seems to say: 1. Does this mean that it is possible to have multiple IP addresses mapped to a...

I do not have a static IP for my computer connected by fiber to home. My ISP assigns an IP address by DHCP, is there a way of making my ISP's router at my home remember the address assigned to me by local settings? I do not fully understand but this URL to a how-to guide points to a method...

I am attempting to create a virtual network on VMware using FreeBSD as a router and a firewall. I am relatively new to many of the concepts involved here. I have FreeBSD currently setup as a DHCP server on my vlan(I will eventually switch to static networking), it is issuing addresses on a...

In terms of PF rules (enabled, actively running in my VPS), which way is the best way to allow a DHCP server (of my VPS provider) connect&define an IP to my VPS without any prevention? 1- pass quick proto udp from any to 255.255.255.255 or 2- pass in quick on $ext_if inet proto udp from any...

I have a machine running FreeBSD 12.3 and I am looking for a way to monitor network changes through a shell script, specifically related to the network interfaces. Some examples of things that I would like to detect are: When a network interface changes status (e.g. from active to no carrier)...
