impossible to set a static IP with network manager

[giorsat]

I Installed the latest alpha version of Karmic and I'm not able to set a static ip with network manager. It simply doesn't save the configuration and keep adhcp profile even if I create a different profile from standard auto eth0
is it possible to write the stati configuration manually in some config file ? my pc is useless without network connection (and I can't update either)

You can edit your /etc/network/interfaces to assign a static IP to your ethernet card.

Here's what my eth0 part looks like:

auto eth0 iface eth0 inet static address 192.168.0.3 netmask 255.255.255.0 gateway 192.168.0.1 dns-nameservers 208.67.222.222 208.67.220.220

You can also configure a static lease in your router and put your computer to DHCP.

Personally I've had no luck with network manager since it became part of ubuntu.
Everytime I'd configure a static IP the next boot it would be gone.

I suggest just removing this piece of garbage if it's not working for ya and setup your interfaces file manually as suggested above.

^^^ this is my preferred method. All my devices do DHCP (four computers, two game consoles, a printer and a satellite receiver) and the devices that need static IP addresses get them from the DHCP server.

We do the same thing at the office with several thousand computers - all workstation static addresses are managed on DHCP servers by MAC reservation.

Did You check the "Available to all users" box? ...

I feel your pain, and ended up using wicd. I manually configured it initially, enly for the default manager to clean it all out after 10 minutes.

You should be fill a bug with this problem, else the developers dont see this problem for make a GUI for static IP configuration.

I'm still missing the way how You could encounter problems that You describe. I've had problems with NM but that was in earlier versions of Ubuntu, 8.10 especially, but now it works like a clock, I've had it stopped and hidden in 8.10 and I've restarted using it eventhough I love just using interfaces and resolve.conf files ... Please give us contents of /etc/NetworkManager/nm-system-settings.conf ... and check my previous post in this thread. I'm just missing what could be the problem on Your box. I've reread Your original post and the only difference is that I've deleted original "auto eth0" entry and created new one that NM gave name "Wired connection 1" ... I've edited my interfaces and resolve.conf got automatically re-created by NM. I did not use DHCP, except on chaos around Sept. 15, for quite some time ...

I had this issue in previous ubuntu releases, I thought It was fixed???

Edit:
I just checked on my laptop... can't believe this isn't fixed, I think it's an 2 years old issue!
