Re: 9.04 "Jaunty" eth0 network problems.

I solve problem.
Knetowork-manager does not work . for DHCP or Manual configuration .
So I edit /etc/network/interfaces.

apoc@Ragnarok:~/Desktop$ sudo kate /etc/network/interfaces
[sudo] password for apoc:

# Reedit interfaces to:

auto lo
iface lo inet loopback
address 127.0.0.1
netmask 255.0.0.0

#configuration for eth0

auto eth0
iface eth0 inet dhcp
address 192.168.1.10
netmask 255.255.255.0
gateway 192.168.1.254
# save file then 
sudo /etc/init.d/networking restart

It works for DHCP, but not for static.

Instead of setting the net config manually, I recommend using WICD (http://wicd.sourceforge.net/download.php)

Re: 9.04 "Jaunty" eth0 network problems.

I using DHCP not static and it's doesn't work I don't know why.
I try manual setting ip addresses but doesn't work so I reedit /etc/network/interfaces.
OK I will try with WICD . Thx

Hmmm... not sure why DHCP's not working. That's what I'm using with for this machine (with KNetworkManager). Maybe I'm not having problems with it because I never attempted to change the settings from my 8.10 install.

On all my other machines (where I use static addresses), I use WICD. It always "just works", as opposed to KNetworkManager... which still seems to be going through growing pains with each release. I don't think you'll be sorry for giving WICD a try.

Re: 9.04 "Jaunty" eth0 network problems.

Hi guys.

Since Kubuntu 8.04 I am looking for a solution to the static IP problem on eth0 WITHOUT any manually editing of some config file and WITHOUT deinstalling Knetworkamanger and switching to WICD. I know it works in Ubuntu/Gnome and it works it OpenSuse 11.1(?, I mean the most up-to-date one) with KDE 4.1. I am not a developer guy, just a "normal" user. I understand that there were some things going wrong in the 8.10, release which caused a total functionality loss of the Knetworkmanager and by searching for a solution I ran across a comment/apology from some Kubuntu dev. I totally understand that errors cannot be avoided and really honour all the work and time spent on developing Kubuntu, but that static IP problem (which still remains in my case, using an updated 8.10), is really annoying. In my case, I need static Ips to enter the network of my university. I have at least 3 university friends which are willing to switch to kubuntu (from WinXP) but with this problem remaining in 8.10 and now, against my hope, perhaps even in 9.04 (I know it is still alpha)...I just want to say to the dev's: Please, please solve this problem. If it just were some minor bug in some app... but not being able to connect to the internet is about the worst thing that could happen, because you also loose your only chance to solve the problem yourself!

So, does anybody know if this problem is on the radar of the Kubuntu dev's and is getting fixed?

It just would be a real pity if I had to change to some other distri JUST because of that bug because I really like Kubuntu. And now with KDE 4.2 out....Jesus!..please fix that BUG!!

Re: 9.04 "Jaunty" eth0 network problems.

I can't look now, as i got my Jaunty Installation at home and i only have Ubuntu here, but if I get you right, you want a static ip configuration to be saved, and you dont want to edit it by hand?

So I think you got three options:

1) I think in KNetworkmanager you can specify your own connection. You have the option there to set a static ip.
2) install Gnome Networkmanager (Fedora does this for their KDE edition I think)
3) Make a short script

I'll look up at 1) when I'm at home. Greetings

Re: 9.04 "Jaunty" Static IP issues

Yup,

I think you're right. Even if I make a new connection in the network manager, and store the IP address, its still no go. For those who don't know, here's how you set things up manually (this can be done in a simple shell script, if you wish):

ifconfig eth0 192.168.1.10 netmask 255.255.255.0
route add -net 0.0.0.0 192.168.1.1
echo nameserver 192.168.1.1 > /etc/resolv.conf

You probably do not need to use the the netmask part of the ifconfig command - although I do where I work, so I've put it in for completeness.

In the route command, the 192.168.1.1 would be the address of your router.

The address on the third line could be that of your router, an openDND address or one of your ISP's nameserver. Personally I put two nameservers in resolv.conf, and you could do this by adding a fourth line, like this:

echo nameserver 192.168.1.2 >> /etc/resolv.conf

Note the two > signs, which says to append to the file.

Hopefully this will be helpful to some.

Best Regards,

Paul

According to man resolv.conf only three nameservers can be listed in resolv.conf.

Re: 9.04 "Jaunty" eth0 network problems.

After all the problems I have had in the past with network manager, I switched to wicd.

This little program is not affected by changing kernels or kernel updates.

So, I am happy and my etho and ath0 and wlan0 work all the time.

Until network manager is finally improved and made foolproof, I will stick with wicd.
