I didn't notice first time that I responded to your mail. Forwarding to
blfs-dev.
I don't like your script since it is tied to one config file and it is
basically a rewrite of ipv4 script. I've taken some time to write a
script of my own. It's in attachment
Place it as /lib/services/wpa, generate wpa configuration file for, eg,
wlan0 by running wpa_passphrase YourSSID YourSSIDPSK >
/etc/sysconfig/wpa_supplicant-wlan0.conf and if using dhcp (isc dhcp -
dhclient service), create /etc/sysconfig/ifconfig.wlan0 with the following:
ONBOOT="yes"
IFACE="wlan0"
SERVICE="wpa"
WPA_SERVICE="dhclient"
DHCP_START=""
DHCP_STOP=""
# Set PRINTIP="yes" to have the script print
# the DHCP assigned IP address
PRINTIP="no"
# Set PRINTALL="yes" to print the DHCP assigned values for
# IP, SM, DG, and 1st NS. This requires PRINTIP="yes".
PRINTALL="no"
Same should work for static-ipv4, just change WPA_SERVICE to whatever is
apropriate and add the rest like it would be.
Any feedback is welcome.
I've updated the script a bit, introduced WPA_ARGS variable that can be
used in ifconfig.interface to pass aditional arguments to wpa_supplicant
command line and did some minor corrections to the last one plus I've
modified dhclient script, so dhcp should work great now. I haven't
tested it with static setup.
Script will be available in blfs-bootscripts package in few hours, I you
can't wait, take it from attachment
