 Posted: Sun May 17, 2020 6:42 am Post subject: Hot plugging net0 on a laptop |
 |
|
I want to hotplug my ethernet, and use it, any time I like. I couldn't find out how to do this.
I ended up bonding wlan0 and net0, but don't think you can use dhcpcd. This works whether the machine boots with or without net0.
| Code: | # rc-update show | egrep "dhcp|wpa|net"
local | default nonetwork
net.bond0 | default
netmount | default
wpa_supplicant | default
|
| Code: | # grep -v '^#' /etc/conf.d/net
config_net0="null"
config_wlan0="null"
modules_bond0="busybox udhcpc"
config_bond0="dhcp"
slaves_bond0="net0 wlan0"
|
| Code: | # grep -v '^#' /etc/modprobe.d/bonding.conf
options bonding mode=1 miimon=100 fail_over_mac=1 primary=net0
|
The following is the result of pinging the firewall while I unplug and reinserting the RJ45.
| Code: |
# ping -D -i 2 192.168.1.1

Are you aware that Network management using DHCPCD does not need those workarounds? |

If I'm not mistaken wpa_supplicant also does hotplugging.
