11 years ago As you can see from the simple script https://github.com/Webconverger/webc/blob/master/etc/webc/wireless
Your wireless config must have been written to /etc/network/interfaces. Could you please http://webconverger.org/debug further Sebastian?

11 years ago Debugged more:
The file /etc/network/interfaces does not contain the string "wireless config", thus the sed line does not have any effect on file. Appending "wireless config" to /etc/network/interfaces and running /etc/webc/wireless manually, will add the 2 entires: wpa-ssid galaxys4 [TAB]wpa-key-mgmt NONE
to the file.

11 years ago I would suggest the following changes: Adding the line "#wireless config" to the end of /etc/network/interfaces. Change the line 58 in /etc/webc/wireless from: sed -i "s,wireless config,$wirelesscfg,g" /etc/network/interfaces
to sed -i "s,#wireless config,$wirelesscfg,g" /etc/network/interfaces
It would be better to have it as a comment in case /etc/webc/wireless would fail in some way, so to not leave a broken wired config incase wireless fails.

11 years ago I don't understand how your /etc/network/interfaces does not look anything like https://github.com/Webconverger/webc/blob/master/etc/network/interfaces
Something must be clobbering it! Did you remove skipconfig?
Your video misses cat /proc/cmdline :)

what is skipconfig and where shoud it be located? I dont find it in boot API?

11 years ago Oops a spelling error, typed the whole cmdline manually, but its really "layout" and not "layoutt".

11 years ago Can you do a reduced example?
For example, just using the Live version:

11 years ago did try that. Same result now.
wec@webconverger:/$ sudo -i root@webconverger:~# cat /proc/cmdline initrd=/live/initrd.img boot=live-ssid=galaxys44 wpa-key-mgmt=NONE BOOT_IMAGE=/live/vmlinuz root@webconverger:~# cat /etc/network/interfaces auto lo iface lo inet loopback

11 years ago however appending skipconfig does yield correct network configuration.
What does skipconfig really do?
sebastiannielsen
commented
11 years ago skipconfig and such "hidden" boot API should really be documented in http://webconverger.org/API/
Im using a custom bootloader with a "permanent" config that I did construct completely from http://webconverger.org/API/ to increase security, so I don't have webconverger to contact the config service. Thats why I have iptables rules in place blocking request to webconverger config service too.

11 years ago skipconfig is part of live-config and not the Webconverger API. You could use noconfig to disable the configuration service.
I tried to set up a wireless config to my Galaxy S4 hotspot.
boot config for wireless are set to: wpa-ssid=galaxys4 wpa-key-mgmt=NONE
Booting in debug and checking /etc/network/interfaces show nothing except for lo and eth0. ifconfig shows only lo and eth0. iwconfig however, shows lo, eth0 and eth1, where eth1 has wireless extensions.
Checking the git code for wireless seems like its only checking ifconfig for presence of the wireless card.
Manually connecting wireless with: iwconfig eth1 essid galaxys4 dhclient eth1
works wonderfully. so theres no driver problem. Maybe your code should check iwconfig aswell, seems like unconnected wireless ifaces are hidden. Also maybe a boot config called "force-iface=XXXXX" where you can force a interface to be used regardless of its presence in ifconfig and iwconfig.
