DietPi-WiFiDB | Add support for hex-encoded characters in SSID #3495

Open IBOYHK opened 4 years ago

IBOYHK commented 4 years ago

The first boot can find the WiFi ssid, but the ssid have some weird name to it as “iBoy’s Home” to as “iBoy\xE2\x80\x99s Home” after select it, and entering the passcode and apply the dietpi still not connect to internet

@IBOYHK Many thanks for your report. Hmm it seems that the WiFi scan command prints found SSIDs with encoded special characters. Probably we can prevent this or otherwise would need to manually decode before applying it to wpa_supplicant.conf.

You should be able to fix it in /etc/wpa_supplicant/wpa_supplicant.conf manually for now.

To verify the assumption, could you please run the following from console and print the output here: iwlist wlan0 scan (if "0" is the correct WiFi interface index).

I need more father details

IBOYHK commented 4 years ago

The pervious of dietpi doesn’t have this erro

MichaIng commented 4 years ago

@IBOYHK Please run the following in console and copy+paste the output of the command here: iwlist wlan0 scan

It should verify my assumption, then I can give you a quick fix command and fix it in our code as well.

@IBOYHK Misterious:

ESSID:"HP-Print-00-Officejet Pro 8630"
ESSID:"iBoy's Guest "
ESSID:"iBoy\xE2\x80\x99s Home "

So it's iBoy's Home only that has encoded character, iBoy's Guest not. Did you use the exact same apostrophe in both cases? E.g. 'and ` or ´ might be treated different.

The following should reveal the character btw: printf "%b" 'iBoy\xE2\x80\x99s Home '

So far I couldn't find some info about which characters are printed in encoded way. In theory we could use the above decoding on all SSIDs but theoretically it is possible that a string that is meant literally contains a part that would be falsely decoded. So I would prefer to know about the likely very few special characters and their encodings to decode only those specifically.

There is an alternative command, even the more modern/supported one, probably it does not show this encoding:

iw dev wlan0 scan | grep SSID

I got this

SSID: iBoy\xe2\x80\x99s Home\x20 SSID: iBoy's Guest\x20 SSID: iBoy\xe2\x80\x99s Home\x20 SSID: iBoy's Guest\x20 SSID: iBoy\xe2\x80\x99s Home\x20 SSID: iBoy's Guest\x20 SSID: HP-Print-19-iBoy's Printer\x20 SSID: FiOS-FBRFK SSID: BZ336 SSID: SSID: HP-Print-00-Officejet Pro 8630 SSID: FIOS-FBRFK SSID: Shark_RV-409f384ce5c7 SSID: FiOS-PK5U7 SSID: SSID: \x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00

Okay conversion works:

root@dietpi:~# echo -e 'iBoy\xe2\x80\x99s Home\x20'
iBoy’s Home
root@dietpi:~# printf '%b' 'iBoy\xe2\x80\x99s Home\x20'
iBoy’s Home

@IBOYHK As you can see, you indeed used a non-standard apostrophe here, while iBoy's Guest contains a standard apostrophe. This seems to be one of the rare characters which iwlist encodes. iw btw encodes the trailing white space as well, since otherwise you would not recognise it in the output, compared to iwlist here double quotes make them visible.

However, since the SSID now is clear, the following should allow you to connect to WiFi:

sed -i '/ssid="/c\ssid="iBoy’s Home "' /etc/wpa_supplicant/wpa_supplicant.conf
sed -i "/aWIFI_SSID[0]='/c\aWIFI_SSID[0]='iBoy’s Home '" /var/lib/dietpi/dietpi-wifi.db
ifdown wlan0
ifup wlan0

I'll think about either adding the conversion of this single special character (very specific since 6 hexadecimal digits), or adding a generic hexadecimal code detection \x[[:xdigit:]][[:xdigit:]] and leave choice to user whether to decode it or not or enter/edit the SSID manually for correction.

Is ok I got it fix

I'll keep this open as feature request, as mentioned above.

I recently ran into the same problem (hex-encoded characters in ssid). I think the solution might be relatively simple if the dietpi-config script used printf escaped characters in these cases: wpa_supplicant.conf supports these hex-encoded characters if provided as a "printf-escaped" string:

# ssid: SSID (mandatory); network name in one of the optional formats:
#   - an ASCII string with double quotation
#   - a hex string (two characters per octet of SSID)
#   - a printf-escaped ASCII string P"<escaped string>"

so in the case of iBoy\xE2\x80\x99s Home, it would have to be something like

network={
    ssid=P"iBoy\xE2\x80\x99s Home"
    psk=<hex encoded passphrase>
}

Where I'm unsure yet is how wpa_passphrase works with printf escaped SSIDs, from a few tests I must conclude that wpa_passphrase needs the ssid in a different format to effectively encode the passphrase.
