I have been brutally forced to go wireless 
I recently purchased a wireless usb adapter and got
it working on my server. Is there a way to get your
onboard lan to pick up wifi so i can plug my phone into that jack
or will i need a network card and will it detect exising wireless
that the computer has running?
Thanks
how have i built a tolerant group of interface?
That is an OS/networking thing, google for network bridging on Centos.
Don’t expect anything to be automatically detected.
I don’t understand what you mean by “onboard LAN” if you have the wireless recognized then you can configure an IP address to the interface.
thanks i will google for more info
What exactly are you looking for? Setting IP address in Linux (CentOS version) is not obfuscated.
I should ask the basics, how do you know that the system recognized the wireless card?
the wireless would have to be reconized because im using the internet on it now with out a hard line connection to the router
and get this wlan0

I only have one onboard lan slot as of now that i would like to dedicate to the phone. but i’m not sure if its for input only. Thats why i was asking if i need
to buy a network card to have lan output to the phone.
Correct me if i’m wrong about this.
sorry
[onboard lan]
is old term for integrated on the motherboard as apposed to pci card or other types of removable cards.
My labtop has the samething and when connected the phone works after a reboot
to resolve conflicting ip.
I dont know anything about labtop hardware nor think i can compare the two ethernet slots to function the same?
Usb is wide open on my desktop if there is a easy solution that way
I know what that reference is, it doesn’t really matter what bus the network adapter is attached to.
I don’t understand what a “input only” interface would be, all Ethernet interfaces are bi-directional and most full-duplex (needed for quality voice).
I assume you installed Asterisk and FreePBX on an existing Linux system? You are surfing the Internet on the same system FreePBX and Asterisk are running on?
You should be able if this is the case to reach the site via the loopback address http://127.0.0.1/admin/config.php
If you know how to pull all this info do you not know how to set an ip address on an interface? By default Asterisk binds to all interfaces.
Is the error you are receiving look like the one below?
If it is this is whatever program the FreePBX runs each time you log in. It appears that this program throws an error if there is no IP address assigned to a network interface. The system below has 3 interfaces ETH0 and ETH1 are physical Ethernet interfaces and TUN0 is a VPN interface. ETH1 is not being used and has no IP assigned.
Exception while fetching interface information for eth1: [Errno 99] Cannot assign requested address

yes the above is the exact error i get.
no i dont know how to set an ip address on an interface? By default Asterisk binds to all interfaces.
yes i can access http://127.0.0.1/admin/config.php
is it bad to surf the web with the same pc? or just not recommended? help to set an ip address on an interface would be good
I did not know they were bi-directional, thats good.
Below is a link that talks about channel bonding interface,
Am i on the right page to begin here and bond eth0 to wlan?
Reading further what you are trying to do then use bridging not bonding or do the Skyking thing and just add an address to eth0 and let asterisk do the bridging.
hi Dicko
Im getting ready to edit vi /etc/sysconfig/network-scripts/ifcfg-eth0
which is currently
#Configuration automatically generated via the PBXact Utility
#DO NOT HAND MODIFY THIS FILE!
#generated: Fri, 01 Mar 2013 23:33:15 -0500
DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes
changing to:
vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
HWADDR="00:21:70:10:7E:CD"
NM_CONTROLLED="no"
ONBOOT="yes"
BOOTPROTO=static
IPADDR=10.16.1.106
NETMASK=255.255.255.0
GATEWAY=10.16.1.1
Is that right?
can i modify or will PBXact Utility have issue with manual modifacation?
I don’t know I don’t use PBXact. Try it and see ?
Some of the commercial modules need the name updated. PBXaxt is the closed source product.
I think i may be making a little progress.
It looks like eth0 is bonded but the phone still waits network to initialize.
I followed these steps.
created /etc/sysconfig/network-scripts/ifcfg-bond0

ONBOOT=yes
BOOTPROTO=none
USERCTL=no

created /etc/modprobe.d/bonding.conf
alias bond0 bonding

DEVICE=eth0
USERCTL=no

BOOTPROTO=none

then ran

I understand this may be a seperate issue but i get this failure when
i [root@PlcmSplp network-scripts]# /etc/init.d/dhcpd restart

last but not least a kernel panic has accured once # ifenslave bond0 eth0 wlan was ran and sometimes
when i manually shut down a network. I’m doing some reading here http://www.novell.com/support/kb/doc.php?id=7004798
and was wondering if someone can suggest a propper bonding driver upgrade
that seems to be available above to eleminate the kernel panic
Thanks
Wow, that’s possibly the most work I have ever seen anyone do that was counter productive.
I have not idea what you are doing. You have somehow built a fault tolerant group of the wireless interface?
Why did you simply not assign another IP to the Interface?
I tried but simply adding ip didnt seem to work
even after running ifconfig eth0 up, i get no carrier next to broadcast
For some reason… I have found myself in the same boat…
I have deployed several freepbx units with multiple ethernet interfaces. Each one is quite unique.
Then I decided to install from the latest “iso”. Big mistake so far.
I configured my system propper before every touching the freepbx guis. With the freepbx guis- I went from a perfect ifcfg-eth0/ifcfg-eth1 to a useless ifcfg-eth0 which has crippled my machine. I am unable to “add” an eth1 through the freepbx gui. after flushing freepbx, reconfiguring unix… … now I am foreced to “chroot” "/"etc/sysconfig/network-scripts so the freepbx gui can exercise its godlike dominion over my netstack without killing my box. What a serious time cost to me and those whos arms are folded, looking at thier watches and tapping their feet. I played this game before and should have remembered.
Next time:
After the box is functional from a networking point of view and I can remotely admin the box:::
sudo /usr/bin/chattr +i /etc/sysconfig/network-scripts/ifcfg-eth*
Let the overlord try to figure out why he can’t brick my box.
