I am running arch Linux and have used this rc-local service:

[Unit]
Description=/etc/rc.local compatibility

[Service]
Type=oneshot
ExecStart=/etc/rc.local
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

This is my rc.local:

#!/usr/bin/env bash
iwconfig wlp6s0 frag 256
iwconfig wlp6s0 rts 256
iwconfig wlp6s0 retry 7
exit 0

The only command that gets run is the retry one. I can see this using the output of sudo iwconfig which returns:

wlp6s0    IEEE 802.11abg  ESSID:"Hoersdal 5G"  
          Mode:Managed  Frequency:5.18 GHz  Access Point: 54:A0:50:5B:C2:34   
          Bit Rate=117 Mb/s   Tx-Power=200 dBm   
          Retry short  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality=35/70  Signal level=-75 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

How do I fix this ? BTW I have made it executable by using sudo chmod +x /etc/rc.local

  • Could it be the interface is not yet fully configured in the first commands? Try to run an iwconfig redirected to a file as the first command to test it out. Commented May 3, 2016 at 12:20
  • It didn't output to a file even though I tried. Why might this actually be the answer and how do I fix it. Commented May 3, 2016 at 12:23
  • Would you mind redirecting the stderr too and trying again? (I am not ignoring the rest of your question, it just might be easier answering it in one go it stderr confirms my suspicion) Commented May 3, 2016 at 17:03

It is most likely trying to run the commands and failing because the iwconfig executable can't be found - because there's no $PATH variable available. You should always use absolute pathnames in cron scripts and similar and not rely on a $PATH setting that might not be there.

  • ExecStart has an absolute value. Commented May 3, 2016 at 12:11
  • But that doesn't explain why the retry line worked. Commented May 3, 2016 at 12:12
  • Yeah, I'm quite confused about that. Commented May 3, 2016 at 12:12
  • John it didn't work, I used /bin/iwconfig instead and it still didn't work. I didn't think so in the first place though because it did execute one of the commands. Commented May 3, 2016 at 12:20
