>Synopsis: after booting, laptop connects to neighbor's open wifi
hotspot, which is not listed in my /etc/hostname.if
>Category: not sure, sorry (networking?)
>Environment:
System : OpenBSD 6.4
Details : OpenBSD 6.4 (GENERIC.MP) #6: Sat Jan 26 20:37:44 CET 2019
[email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
I use /etc/hostname.if to automatically connect to wifi when I boot
my Thinkpad laptop. When at home, I'm within range of several neighbors'
hotspots, one of which does not have a password. My laptop sometimes
joins that neighbor's hotspot during boot, even though his ssid is not
in my /etc/hostname.athn0.
Here are the contents of my /etc/hostname.athn0:
!sh /home/bruno/bin/mac-generator
!ifconfig \$if lladdr $(cat /home/bruno/.fakemac)
!ifconfig \$if mode 11g
join bibliotheca_alexandrina wpakey somePassWorD
join AndroidAP-bd wpakey soMepaSSwoRd
join ARMCVisitor
dhcp
Here is the output of 'ifconfig athn0 joinlist':
bruno@thinkpad:~391$ ifconfig athn0 joinlist
athn0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
lladdr 00:26:b6:eb:9d:23
index 2 priority 4 llprio 3
groups: wlan egress
media: IEEE802.11 autoselect mode 11g (OFDM18 mode 11g)
status: active
ieee80211: join ARMCVisitor chan 1 bssid 00:e1:6d:63:57:45 -40dBm
join: bibliotheca_alexandrina
AndroidAP-bd
ARMCVisitor
inet 10.1.72.144 netmask 0xffffe000 broadcast 10.1.95.255
Neighbor's hotspot is named "xfinity". When I find that I'm
connected to his network after booting, I get this (yes, it shows "nwid"):
bruno@thinkpad:~391$ ifconfig athn0 joinlist
athn0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
...
ieee80211: nwid xfinity ...
>How-To-Repeat:
Reboot several times until the problem recurs.
>Fix:
If I find that I'm connected to neighbor's wifi after a reboot, running
# sh /etc/netstart athn0 fixes the problem (i.e., after the command,
output of ifconfig athn0 shows "ieee80211: join bibliotheca_alexandrina"
as expected).
