Run as service? (Also speed performance issue)

[gitxmax]

Hello, thank you for your job. I tried running this (on Raspberry 3, with 2 external usb dongles), as well as the original create_ap and just like the original script, it seems to have an issue, with the interfaces, if run from crontab. Any chance to run it as a service, so it will be much easier, to run it at start up? Also both the script seem to have an issue, with wlan0 -> wlan1 relay. The speed is cut drastically, best I can get is 50% less download rate on wlan1, compared to wlan0. The upload speed seems unaffected that much. I know the hardware can perform a lot better, since running the LEDE, on the set up, only has around 10% downgrade. For additional information, on-board wifi disabled, as well as network-manager is off. Clean install of debian.

Thanks again.

Hello, Thank you for feedback! Do you mean service the systemd .service? create_ap had it and a .conf file to work with. I deleted it to make the job simpler. However you can write your own .service file with arguments in ExecStart=.

This is needed right now! Thank you so much!

This is what I'm working on, but I can't get the router to launch in a usable state automatically on boot using any of the three methods that follow

It will launch and broadcast an ap, but nothing will connect to it.

If I run this from cli it works as expected $ sudo ./lnxrouter --random-mac --ap wlan0 netgear0 -p testpass -c 3

If I try to set it as a systemd service things look good but nothing can connect to the ap (worth noting that starting the service manually after boot produces no change, enabling, disabling, stopping / starting, etc.. )

$ sudo systemctl status router.service router.service - linux-router Loaded: loaded (/etc/systemd/system/router.service; disabled; vendor preset: enabled) Active: active (running) since Sun 2021-03-07 22:19:40 UTC; 2s ago Main PID: 3091 (lnxrouter) Tasks: 7 (limit: 4915) CGroup: /system.slice/router.service ├─3091 /bin/bash /home/ubuntu/Downloads/linux-router-master/lnxrouter --ap wlan0 netgear0 ├─3202 /bin/bash /home/ubuntu/Downloads/linux-router-master/lnxrouter --ap wlan0 netgear0 ├─3205 sleep 2 ├─3206 hostapd -P /dev/shm/lnxrouter_tmp/lnxrouter.wlan0.conf.3u7/hostapd.pid /dev/shm/lnxrouter_tmp/lnxrouter.wlx984> ├─3207 /bin/bash /home/ubuntu/Downloads/linux-router-master/lnxrouter --ap wlan0 netgear0 ├─3208 sleep 3 └─3209 sleep 10 Mar 07 22:19:40 ubuntu linux-router[3091]: Use random LAN IPv4 address 192.168.247.1 Mar 07 22:19:40 ubuntu linux-router[3091]: WARN: Wifi is not protected by password Mar 07 22:19:40 ubuntu linux-router[3091]: Set wlan0 unmanaged by NetworkManager Mar 07 22:19:41 ubuntu linux-router[3091]: haveged_watchdog PID: 3202 Mar 07 22:19:41 ubuntu linux-router[3091]: Starting hostapd Mar 07 22:19:41 ubuntu linux-router[3091]: hostapd PID: 3206 Mar 07 22:19:41 ubuntu linux-router[3206]: Configuration file: /dev/shm/lnxrouter_tmp/lnxrouter.wlan0.conf.3u7/hostapd.conf Mar 07 22:19:42 ubuntu linux-router[3206]: Using interface wlan0 with hwaddr 98:48:72:da:de:ba and ssid "netgear0" Mar 07 22:19:42 ubuntu linux-router[3206]: wlan0: interface state UNINITIALIZED->ENABLED Mar 07 22:19:42 ubuntu linux-router[3206]: wlan0: AP-ENABLED

I've tried a number of changes in the .service file but there has been no change. Referanced the create-ap .service file too. I can't say I've tried a conclusive set of params, but .service is where I've spent most of my time. Worth noting is I've tried these w/o auth, channel, and random-mac params. no change

$sudo nano router.service [Unit] Description=linux-router After=network.target [Service] Type=simple ExecStart=/home/ubuntu/Downloads/linux-router-master/lnxrouter --ap wlan0 netgear0 KillSignal=SIGINT Restart=always RestartSec=10 StandardOutput=syslog StandardError=syslog SyslogIdentifier=linux-router [Install] WantedBy=multi-user.target

I've tried rc.local, I'm sure I'm doing something wrong here because it won't launch/broadcast at all. It is chmod +x

#!/bin/sh -e -p /home/ubuntu/Downloads/linux-router-master/lnxrouter --random-mac --ap wlan0 netgear0 -p testpass -c 3 & exit 0

I've also tried starting it with $ gnome-session-properties

using the same command $ sudo ./lnxrouter --random-mac --ap wlan0 netgear0 -p testpass -c 3

Still results in a broadcast that I can't connect to. Tried several things including cell phones, computers, and an amazon fire stick (lol)

its running on a raspi / ubuntu 20.10 server

It may be worth noting that I am using two seperate interfaces for wifi. internal is recieving, usb is broadcasting

Any idea what I may be doing wrong here?

@eschwelgin Is that all log? Didn't see iptables and dnsmasq.

├─3206 hostapd -P /dev/shm/lnxrouter_tmp/lnxrouter.wlx984827adde1a.conf.3u7/hostapd.pid /dev/shm/lnxrouter_tmp/lnxrouter.wlx984>

Mar 07 22:19:41 ubuntu linux-router[3091]: hostapd PID: 3206 Mar 07 22:19:41 ubuntu linux-router[3206]: Configuration file: /dev/shm/lnxrouter_tmp/lnxrouter.wlan0.conf.3u7/hostapd.conf

Why different configuration folder name? lnxrouter.wlan0.conf.3u7 and lnxrouter.wlx984827adde1a.conf.3u7

You chould try adding iptables.service and networkmanager.service as dependency. Try add a 2-minutes delay before calling lnxrouter to to have system boot completely

I've tried rc.local, I'm sure I'm doing something wrong here because it won't launch/broadcast at all. It is chmod +x

#!/bin/sh -e -p /home/ubuntu/Downloads/linux-router-master/lnxrouter --random-mac --ap wlan0 netgear0 -p testpass -c 3 & exit 0

If use script, your script should be something like

sleep 120  # try a long enough delay
/home/ubuntu/Downloads/linux-router-master/lnxrouter --random-mac --ap wlan0 netgear0 -p testpass -c 3 &
sleep 2   # this sleep is must
disown -a  # must !
sleep 2  # this sleep is must
exit 0 # then you can exit

I cleaned up my op to make some of the outputs a bit clearer, and to fix a mistake. sorry for the confusion.

Is that all log? Didn't see iptables and dnsmasq.

Thats the second part of the output from systemctl status, I added the commands above and deleted the space in the middle of the output to make it a bit clearer

Why different configuration folder name? lnxrouter.wlan0.conf.3u7 and lnxrouter.wlx984827adde1a.conf.3u7

Sorry I changed all of the wlx984827adde1a to wlan0 for clarity, I must have missed that one. They are all the same

You chould try adding iptables.service and networkmanager.service as dependency. Try add a 2-minutes delay before calling lnxrouter to to have system boot completely

This produces no change. Router still broadcasts but nothing will connect to it. Here's my updated .service file

[Unit] Description=linux-router After=network.target iptables.service networkmanager.service [Service] Type=simple ExecStart=/home/ubuntu/Downloads/linux-router-master/lnxrouter --ap wlx984827ad> KillSignal=SIGINT Restart=always RestartSec=10 StandardOutput=syslog StandardError=syslog SyslogIdentifier=linux-router [Install] WantedBy=multi-user.target

I also tried starting the service manually (disabled on startup, systemctl start) after the system had booted. Still runs with issues, broadcast ap / no connections)

I also managed to get it running from rc.local. Surprisingly enough it was because I forgot the & at the end of the command to allow it to fork. I ran it like this for a while and it still ran with the same issues, broadcast ap / no connections. I fixed the file and booted back into grub, where I ran rc.local manually, and in that state it worked as expected.

It really seems to me like any type of background / automatic start state results in the same issue, where it broadcasts the ap but nothing will connect to it. Any time I start it manually, through the cli or a script including rc.local) it runs as expected.

The only other thing to note, last night I was playing around with it and although I don't remember the exact circumstances, I was seeing the errors from check_wifi_settings() "WARN: Using 'iwconfig', not as good as 'iw'" and "ERROR: Can't use 'iwconfig' to operation this WiFi interface neither". I'm sorry that I can't seem to reproduce today, but it was right before I forgot the & in rc.local and gave up for the night

I appreciate your help

I tried to run by systemd. Turned out dnsmasq failed In dnsmasq.conf

log-facility=/dev/stdout

causes error

cannot open log /dev/stdout: No such device or address

in systemd environment. (You could try modifying StandardOutput=syslog to something else )

For a quick workaround you can delete log-facility=/dev/stdout

BTW, I have to fix watchdog. It didn't react when dnsmasq fails. (and it couldn't recognize zombie process)

[garywill]

@eschwelgin Changed how dnsmasq outputs. Now it uses named pipe. You could try it again.

Sorry to reopen an old thread but I tried to run lnxrouter using a script:

`#!/bin/sh -e -p

sleep 120

/usr/sbin/lnxrouter -i eth0 &

sleep 2

disown -a

sleep 2

exit 0`

This script is launched by cron (@reboot) on a Raspberry Pi 4 and gives internet to an AVM Fritz Extender that should run a wifi network. If I launch lnxrouter -i eth0 manually it works fine, but on reboot I have a running router that I cannot connect to because does not receive an IP address. Any hint about it? Thank you

Just because nobody else said so explicitly: this works now. Here is my service definition lnxrouter-hotspot.service

[Unit]

N.B. to other readers: you may not want --no-virt

I came here to try this script after failing to get my USB 148f:5370 Ralink Technology, Corp. RT5370 Wireless Adapter working in ap mode using nmcli with WPA-PSK (or even WEP, shudder). Setting things up "the old-fashioned way" using lnxrouter worked GREAT.

Thank you for this script!
