 Posted: Mon Jun 23, 2014 7:16 pm Post subject: slow ping resonse with ifplugd and config in /etc/conf.d/net |
 |
|
I just emerged ifplugd and configured /etc/conf.d/net to monitor my wired interface (enp0s25). I want my wireless interface (wlp3s0) to "take over" when my ethernet cable is pulled and vica versa.
/etc/conf.d/net
| Code: | # Let ifplugd monitor the wired interface enp0s25
# Config hints can be found in /usr/share/doc/netifrc-0.1/net.example
# The following seems to work - but slow ping response when enabled!
ifplugd_enp0s25="..."
ifplugd_enp0s25="--api-mode=wlan"
# --- Wired ethernet ---
config_enp0s25="dhcp 192.168.1.250/24"
# config_eth0="dhcp" ?
# --- Wireless WiFi ---
#Prefer wpa_supplicant over wireless-tools
modules_wlp3s0="wpa_supplicant"
# It is important that we tell wpa_supplicant which driver we should
# be using as it is not very good at guessing that
wpa_supplicant_wlp3s0="-Dnl80211 -d -f /var/log/wpa_supplicant.log"
config_wlp3s0="dhcp" |
The atomatic switch to wlan works when I pull the ethernet cable. But a side effect is that response on ping becomes very slow. Normally ping swiftly "tics" ping responses (at least every second). But with the configuration
| Code: | ifplugd_enp0s25="..."
ifplugd_enp0s25="--api-mode=wlan" |
I get a ping response approx every 5 seconds.
Can anyone explain this? Is there a cure?

philip ... well, you're not telling netifrc/openrc that the interface is plugged ...
/etc/conf.d/net
| Code: | modules_wlp2s0="!plug wpa_supplicant dhcpcd"
config_wlp2s0="dhcp"
wpa_supplicant_wlp2s0="-Dnl80211 -qq"
modules_enp0s25="plug dhcpcd"
config_enp0s25="dhcp 192.168.1.250/24"
ifplugd_enp0s25="--no-beep" |
That should be all that's needed for netifrc ... you would then add something like the following to /etc/ifplugd/ifplugd.action
| Code: | case "$2" in
up)
if [ "${INITNG}" = "yes" ] ; then
ARGS="-u net/$1"
else
/etc/init.d/net.wlp2s0 --quiet stop
ARGS="--quiet start"
fi
;;
down)
if [ "${INITNG}" = "yes" ] ; then
ARGS="-d net/$1"
else
ARGS="--quiet stop"
/etc/init.d/net.wlp2s0 --quiet start
fi
;;
[blah, blah] |
Then you would remove net.wlp2s0 from the default runlevel, as it should be automatically started by ifplugd if no network cable it detected ...
| Code: | | # rc-update del net.wlp2s0 default |
I don't use ifplugd but the above should work as expected.
BTW, the ping time is probably due to having two devices on the same subnet ...
best ... khay |

Thanks again khyyam!
I put in the changes you suggest above. It almost works now. But not quite as expected.
When the ethernet cable i plugged and the WiFi is connected (plugged so to speak), then both interfaces are up
| Code: | # ifconfig enp0s25 && ifconfig wlp3s0
enp0s25: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 0.0.14.40 netmask 0.0.0.0 broadcast 255.255.255.255
inet6 fe80::56ee:75ff:fe07:8c8e prefixlen 64 scopeid 0x20<link>
ether 54:ee:75:07:8c:8e txqueuelen 1000 (Ethernet)
RX packets 1267 bytes 82214 (80.2 KiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 8 bytes 680 (680.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
device interrupt 20 memory 0xf0500000-f0520000
wlp3s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.1.210 netmask 255.255.255.0 broadcast 192.168.1.255
inet6 fe80::7e7a:91ff:fea3:2f5a prefixlen 64 scopeid 0x20<link>

RX packets 2028 bytes 522585 (510.3 KiB)
RX errors 0 dropped 541 overruns 0 frame 0
TX packets 1457 bytes 189244 (184.8 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 |
and
| Code: | # ifplugstatus
enp0s25: link beat detected
wlp3s0: link beat detected |
Ping works swiftly and is probably transmited over the Wifi i/f'
When I pull the ethernet cable, then
# ifconfig enp0s25 && ifconfig wlp3s0
| Code: | enp0s25: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
inet 0.0.14.40 netmask 0.0.0.0 broadcast 255.255.255.255
inet6 fe80::56ee:75ff:fe07:8c8e prefixlen 64 scopeid 0x20<link>
ether 54:ee:75:07:8c:8e txqueuelen 1000 (Ethernet)
RX packets 1460 bytes 94566 (92.3 KiB)

TX packets 8 bytes 680 (680.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
device interrupt 20 memory 0xf0500000-f0520000
wlp3s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.1.210 netmask 255.255.255.0 broadcast 192.168.1.255
inet6 fe80::7e7a:91ff:fea3:2f5a prefixlen 64 scopeid 0x20<link>
ether 7c:7a:91:a3:2f:5a txqueuelen 1000 (Ethernet)

The wired ethernet i/f enp0s25 is still up, but
# ifplugstatus
| Code: | enp0s25: unplugged
wlp3s0: link beat detected
enp0s20u4: unplugged
lo: link beat detected
sit0: unplugged |
In other words the enp0s25 i/f is still up but is detected as unplugged.
The ping goes on seamlessly, still over the WiFi i/f.
Shouldn't the wired i/f enp0s25 go down when the wireless i/f wlp3s0 up when the ethernet cable is pulled. And vice versa when the eth cable is put back in again?

I doscovered an error by me
I had in /etc/conf.d/net
| Code: | | ifplugd_enp0s25="--no--beep" |
which is wrong syntax and should be
| Code: | | ifplugd_enp0s25="--no-beep" |
But stil the wired enp0s25 i/f is not brought down and up as I pull and plug the ethernet cable....
My configuration looks like this now
# cat /etc/conf.d/net
| Code: | # Let ifplugd monitor the wired interface enp0s25
# Config hints can be found in /usr/share/doc/netifrc-0.1/net.example
# Tell netifrc/openrc when the enp0s25 is plugged
# --- Wireless WiFi ---
# Prefer wpa_supplicant over wireless-tools
modules_wlp3s0="!plug wpa_supplicant dhcpcd"
config_wlp3s0="dhcp"
# Tell wpa_supplicant which driver to be used, which logfile to use
# and that extra verbose output should be made to the logfile (-qq)
wpa_supplicant_wlp3s0="-Dnl80211 -d -f /var/log/wpa_supplicant.log -qq"
# --- Wired ethernet ---
modules_enp0s25="plug dhcpcd"
config_enp0s25="dhcp 192.168.1.250/24"
ifplugd_enp0s25="--no-beep" |

phil ...
I'm not entirely sure why that's happening, and as I don't have ifplugd installed its difficult for me to check. I suspect that ifplugd is trying to manage both interfaces, please try the following:
/etc/conf.d/net
| Code: | | ifplugd_enp0s25="--no--beep --iface=enp0s25" |
/etc/ifplugd/ifplugd.conf (if it exists ... otherwise don't worry about it) ..
| Code: | | INTERFACES="enp0s25" |
Also, but unrelated ... the '-d' option for wpa_supplicant turns on debug (similarly with '-dd' and '-ddd'), and the '-qq' makes the output 'quiet', so having both, and providing a log, isn't advisable ... just turn on debug/logging as and when needed ... otherwise use the following:
| Code: | | wpa_supplicant_wlp3s0="-Dnl80211 -qq" |
best ... khay |
