[9fans] Prompt for wpapsk during wifi boot

[9fans] Prompt for wpapsk during wifi boot

[Luis]

According to plan9.ini(8):
wpapsk=password
 WPA/WPA2 encryption is detected automatically and a prompt
 for the password will appear when using the WIFI interface
 for netbooting. To avoid the prompt, the password can be
 specified with the boot parameter above.

However, I do not get said prompt, and when I try to netboot with this
configuration:
 ether0=type=iwl
 essid=myessid
 bootargs=tls!-g 192.168.1.1 ether /net/ether0
That (obviously, as I did not enter my wifi creds) fails with
"ipconfig: no success with DHCP."

It works if I escape to shell with !rc and run aux/wpa manually.

How do I get aux/wpa to automatically prompt for a password OR to
permanently store the password for use at boot time?

not sure what other problems there may be, but make sure essid appears on the same line as ether0.

Ok, Thanks. The Problem does persist with essid= on the same line as
ether0=.

I recall having issues as well with this.  My current plan9.ini uses
the bssid= rather than the essid= for the wireless network I'm
connecting to, but I don't think it does anything because in my user's
profile I run a script to connect to wifi *after* I start up factotum:

% cat /bin/wifi/auth
#!/bin/rc
if (~ $ether '')
    ether=`{cd /net; ls -d ether*}
for (e in $ether ) {
    if (grep -s 'status: need authentication' /net/$e/ifstats) {
                essid=`{grep '^essid: ' /net/$e/ifstats | sed 's/essid: //'}
                if (grep -s 'essid=.*'^$"essid /mnt/factotum/ctl) {
                        aux/wpa /net/$e
                        ip/ipconfig ether /net/$e
                }
                if not echo 'No factotum key found for essid:'^$"essid >[1=2]
        }
}

So the wpapsk= probably didn't work for my situation or I didn't know
how to wield it.  If either of those was the case, perhaps I didn't
want to type the password each time and I was okay with waiting for my
profile to be run.

I’ve had issues with wifi in the past and normally just end up following this approach: 
https://9lab.org/plan9/thinkpad-t420s/.  It works well and allows the selection of different essid/network upon boot.

Igor does great work.  So apparently he handles it in the profile (for
the terminal case) as well.

While that looks promising, does this work when booting over wifi to a
remote fileserver? In the example the T420s boots to its local disk,
loading lib/profile and therewith bin/rc/initwifi. Loading these
scripts from the fileserver would however require already having a
network connection, or am I missing something?

No, I don't think you're missing anything.

you may do it by changing kernel's paqfs i think.
