[SOLVED] wpa_supplicant collides with network service

rotorstart · 07-08-2010, 08:51 PM

I have wpa_supplicant configured and working along with the network service. eth1 is the designated wireless interface. If S10network and S12wpa_supplicant start up the usual way, "iwconfig eth1" will shows nothing, but instead 'iwconfig peth1' will show wireless signal. If I dont' start up network during boot up and just wpa_supplicant, then once the server is up, I bring up the network with "service network start", eth1 is configured nicely and "iwconfig eth1" will show signal. That will work fine. Any input is appreciated.

# cat ifcfg-eth1

# cat /etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel

pairwise=CCMP TKIP
group=TKIP
psk=1fc843f6d9eee91f6ca5abe1a59c1432512f6f2ef50e39
}

# cat /etc/sysconfig/wpa_supplicant
# Use the flag "-i" before each of your interfaces, like so:
# INTERFACES="-i eth1 -i wlan0"
INTERFACES="-i eth1"

# Use the flag "-D" before each driver, like so:
# DRIVERS="-D wext"
DRIVERS="-D wext"

# Other arguments
# -u Enable the D-Bus interface (required for use with NetworkManager)
# -f Log to /var/log/wpa_supplicant.log
OTHER_ARGS="-f /var/log/wpa_supplicant.log"

Edit: This has been solved by turning off network bridging in Xen.

You might want to check your udev rule set(s) for network name settings. On most systems, udev is run as soon as the initial RAM file system transfers control to your initialization script. On my Fedora laptop the rule set looks like this:

Code:

$ cat /etc/udev/rules.d/70-persistent-net.rules 

# This file was automatically generated by the /lib/udev/write_net_rules
# program run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single line.

# nVidia Corporation MCP67 Ethernet (rule written by anaconda)
