Solved wpa_supplicant error no /dev/fd//63 config file

hi i am trying to get wifi going and i am following the wike wireless network configuration.  Did all steps to wpa_supplicant -B -i wlp3s0 -c (wpa_passphrase MYSSID passphrase) but get this error

Successfully initialised wpa_supplicant
Failed t open config file '/dev/fd/63', error no such file or directory

I already run sudo wpa_passphrass  myssid my passphrase - wpa/wpa2 encryption.

Any ideas of that error.  My wireless is atheros ar 9462 and the ath9k driver is loaded.

thanks

wpa_supplicant -B -i wlp3s0 -c (wpa_passphrase MYSSID passphrase) 

You are missing an `<`...

Re: Solved wpa_supplicant error no /dev/fd//63 config file

If I i do
sudo wpa_supplicant -B -i wlp3s0 -c <(wpa_passphrase MYSSID passphrase )

I get the same error no config file /dev/fd/63

If I do the same command as normal user I get
could not set interface wlp3s0 flags (Down):operation not permitted
repeated several times
then
nl80211:could not configure driver mode
wlp3s0 failed to initialise driver interface

I am writing this on another laptop

Before I entered the wpa_supplicant command I was reading the wiki on wpa_supplicant and I used the comman
sudo wpa_passphrase myssid passphrase but I did not save it anywhere.  Perhaps this is issue.  I see further down on the wike sudo wpa_passphrase ssid  passphrase > /etc/wpa_supplicant/example.  But what to do then?

Re: Solved wpa_supplicant error no /dev/fd//63 config file

ok I got it working with I may say not much help form the forum. 

sudo wpa_passphrase my ssid my wpa passphrase </etc/wpa_supplicant/example.conf. 
then I put in the other lines in the example.conf on the wpa supplicnt wiki page.  Then I read this page lucily
https://help.ubuntu.com/community/WifiDocs/WPAHowTo

I then entered sudo wpa_supplicant -iath9k -iwlp3s0 -c/etc/wpa_supplicant/example.conf

and it worked. Connection commpleted.  I can now surf the net.  So I know now it works and can hopefully go on from here to get it working with networkmanager or something in kde.  But how?

That's because it is in the wiki...

Re: Solved wpa_supplicant error no /dev/fd//63 config file

I bumped into the same problem, solved it and decided to post solution here since this thread appears on Yandex search.

If I i do
sudo wpa_supplicant -B -i wlp3s0 -c <(wpa_passphrase MYSSID passphrase )

One shouldn't run this command as sudo because `<' redirection does not work as expected with some sudo commands.
Run this in a root shell, i.e. after you launch it with `sudo -s'.

PS There is a good explanation of this error on StackExchange

Please do not necrobump, skoval, especially with information that is well documented on the wiki.
