Manual IP configuration doesn't work in knetworkmanager

[Guest]

Manual IP configuration is not working but it works without using it(using DHCP).
When i add a new connection by using manual setting, i won't connect
it's same for both wireless and wire.
I think it isn't the problem with the router because manual IP setting works on Mac and window

I don't want the DHCP server to be enable

Anyone know what to do?

Re: Manual IP configuration doesn't work in knetworkmanager

My network access wouldn't work at all after installing 8.10. No connection was showing in Knetwork-manager, and trying to add one didn't work with either dhcp or static IP. dmesg told me that eth0 was being detected,, started, but then shut down for some reason. The local IP address for the system in question is 192.168.0.1 and the router is at 192.168.0.1, so in a root console, I used the commands
"ifconfig eth0 192.168.0.100 up" and "route add default gw 192.168.0.1" to get it running again, but found the settings were not being retained on a reboot.

To get around the problem until the bug is fixed, I added the above commands to /etc/rc.local so the network is activated on startup.

Re: Manual IP configuration doesn't work in knetworkmanager

I have been reading through this forum to find a solution to the problem I have.

I have tried running "ifconfig eth0..." and so on, but I keep getting an error message telling me "access denied"

I have also tried to edit the etc/network/interfaces file to key in the ip addresses, but I get an erroe message reading that I dont have permission to modify files in that directory. I am loggd in as an admin user, so i dont understand why i dont have permission to modify files or to access the ifconfig command.

Please help

to put it bluntly...Knetworkmanager sucks...

Do a search on how to install wicd. It works well, for both DHCP and Static IP's.

Try it my way.

Even though you are logged in as an admin user, you do not have system wide privileges. This is not Windows. You have to open a file you want to edit as "sudo" unless it in your home directory. To open the interfaces file in edit mode open a terminal and input:

kdesudo kate /etc/network/interfaces

Put in your password if asked, then the file will open in a text editor for editing.

Yes, knetworkmanager has lots of bugs... a step backwards, since in the past I used it to replace the Gnome one.

To supplement Detonate, what you need to do is to edit the /etc/network/interfaces file. So after issuing a

kdesudo kate /etc/network/interfaces

and entering your password to confirm that you want to do this with root privileges you'll have to put in that file the following:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address <Your IP address>
netmask <Your netmask>
gateway <Gateway address>

Take the addresses from the network settings of a Windows or OSX machine that works.

The DNS parameters are in the file /etc/resolv.conf You'll need to do again kdesu /etc/resolv.conf and put the following content here

nameserver <Your first DNS server IP address>
nameserver <Your second DNS server IP address>

Again, copy the addresses from a working XP or MacOS X system

Tried this solution, still no network/internet support.

Re: Manual IP configuration doesn't work in knetworkmanager

Did you restart the interface with ifdown and ifup?

Also, if you have rebooted, could you check whether /etc/resolv.conf still contains the name servers?
On my pc resolv.conf is regenerated after a reboot, but maybe that is only the case when DHCP is enabled.

Anyway, IF you experience that resolv.conf doesn't contain the name server adresses anymore, do this:

edit /etc/dhcp3/dhclient.conf and find this line:

#prepend domain-name-servers 127.0.0.1;

and change it to:

prepend domain-name-servers 208.67.222.222,208.67.220.220,192.168.1.1;

The ip adresses are from opendns and I assumed your router has ip 192.168.1.1. Note that the # has been removed!
