unable to establish network interface at boot with wlan using dhcp
3 Attachment(s)
I can connect to my ISP from a gui but not at boot or from command line. My efforts have centered around the configuration of rc.inet1.conf primarily using Alien Bob's network configuration guide. I must be missing some detail. I will attach outputs for iwconfig, /etc/rc.d/rc.inet1 wlan0_start, and iwconfig from within gui with connection established. Any suggestions would be most welcome. Thank you for your help. below is my rc.inet1.conf:

# /etc/rc.d/rc.inet1.conf
# This file contains the configuration settings for network interfaces.
# If USE_DHCP[interface] is set to "yes", this overrides any other settings.
# If you don't have an interface, leave the settings null ("").

# You can configure network interfaces other than eth0,eth1... by setting
# IFNAME[interface] to the interface's name. If IFNAME[interface] is unset
# or empty, it is assumed you're configuring eth<interface>.

# Several other parameters are available, the end of this file contains a
# comprehensive set of examples.

# =============================================================================

# Config information for eth0:

# Config information for eth1:

# Config information for eth2:

# Config information for eth3:

# Default gateway IP address:

# Change this to "yes" for debugging output to stdout. Unfortunately,
# /sbin/hotplug seems to disable stdout so you'll only see debugging output
# when rc.inet1 is called directly.

# Example of how to configure a bridge:
# Note the added "BRNICS" variable which contains a space-separated list
# of the physical network interfaces you want to add to the bridge.

## Example config information for wlan0. Uncomment the lines you need and fill
## in your info. (You may not need all of these for your wireless network)
WLAN_RATE[4]="54M auto"
WLAN_KEY[4]="[2] s:mysecretpassword key [2]"
##WLAN_IWPRIV[4]="set AuthMode=WPAPSK | set EncrypType=TKIP | set WPAPSK=96389dc66eaf7e6efd5b5523ae43c7925ff4df2f8b7099495192d44a774fda16"

## Some examples of additional network parameters that you can use.
## Config information for wlan0:
#IFNAME[4]="wlan0" # Use a different interface name nstead of
# the default 'eth4'
#HWADDR[4]="00:01:23:45:67:89" # Overrule the card's hardware MAC address
#MTU[4]="" # The default MTU is 1500, but you might need
# 1360 when you use NAT'ed IPSec traffic.
#DHCP_KEEPRESOLV[4]="yes" # If you dont want /etc/resolv.conf overwritten
#DHCP_KEEPNTP[4]="yes" # If you don't want ntp.conf overwritten
#DHCP_KEEPGW[4]="yes" # If you don't want the DHCP server to change
# your default gateway
#DHCP_IPADDR[4]="" # Request a specific IP address from the DHCP
# server
#WLAN_ESSID[4]=DARKSTAR # Here, you can override _any_ parameter
# defined in rc.wireless.conf, by prepending
# 'WLAN_' to the parameter's name. Useful for
# those with multiple wireless interfaces.
#WLAN_IWPRIV[4]="set AuthMode=WPAPSK | set EncrypType=TKIP | set WPAPSK=thekey"
# Some drivers require a private ioctl to be
# set through the iwpriv command. If more than
# one is required, you can place them in the
# IWPRIV parameter (separated with the pipe (|)
# character, see the example).

Note that WPA/WPA2 encryption is not configured just in /etc/rc.d/rc.inet1.conf, you will also need to edit /etc/wpa_supplicant.conf and add an encryption key there.
If you are using a GUI tool to handle network connections (e.g. NetworkManager), then it is suggested that you leave /etc/rc.d/rc.inet1.conf in the default state.

In that case I would recommend using wicd or Network manager.

Thank you for response
Thank you Allend and H_TeXMeX_H for your suggestions. My goal is to have the network interface created at boot and continue regardless of whether I am in a gui or not. I hope to first figure out how to make an unencrypted connection before I try to implement WPA/WPA2. Thanks again. Would appreciate any tips.

wicd has a cli interface as well as a gui one.

It is very likely that the device you are trying to connect to will only accept WPA/WPA2 connections. You will need to use 'wpa_supplicant' directly from the command line if you are using NetworkManager. The 'nmcli' command line tool does not handle the secrets needed for WPA/WPA2.

What if you were to modify your file as follows:
Use ifconfig as root, to detect what ethernet port is available. Assume eth0:


Then make the following changes to /etc/rc.d/rc.inet1.conf:

#WLAN_KEY[4]="[2] s:mysecretpassword key [2]"
##WLAN_IWPRIV[4]="set AuthMode=WPAPSK | set EncrypType=TKIP | set

Then do the following as root:

cat /etc/wpa_supplicant.conf
Most likely the file will contain nothing.


wpa_passphrase 'yourRouterESSID' 'yourpasswordforwpa2' >>/etc/wpa_supplicant.conf
Or, you could have used:

nano /etc/wpa_supplicant.conf
Then do the following as root:

/etc/rc.d/rc.inet1 wlan0_stop
/etc/rc.d/rc.inet1 wlan0_start

If your Ethernet cable is plugged into your Computer, you can start those communications with:

/etc/rc.d/rc.inet1 eth0_stop
/etc/rc.d/rc.inet1 eth0_start

That should work.

I've written down my config some time ago, maybe it gives you some inspiration.

It was WPA
Thank you all for your help. You were right, my connection required WPA encryption.
