I've installed OpenBSD 6.7 on a system that have an athn(4) wireless network adapter. Before setting up this device, I wanted to verify the configuration of pf, unbound etc. which required the interface to have an IP address, so I added the following line to /etc/hostname.athn0:
inet 192.168.10.1 255.255.255.0 This enabled the interface, which allowed pf, unbound etc. to start: # ifconfig athn0 athn0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 lladdr XX:XX:XX:XX:XX:XX index 4 priority 4 llprio 3 groups: wlan media: IEEE802.11 autoselect (DS1) status: no network ieee80211: nwid "" inet 192.168.10.1 netmask 0xffffff00 broadcast 192.168.10.255 However, it also automatically made the interface start scanning: # netstat -W athn0 | grep scans 1 active scans started 0 passive scans started Is it possible to configure the athn0 interface with an IP address, but prohibit any kind of wireless communication? The reason for this is that I have to verify many systems with different configuration, which requires athn0 to be configured with an IP address. I want to do the verification and install patches before any wireless communication happens, as I can't guarantee that none of the devices within wireless range are malicious. Regards, Mogens Jensen
