Fedora 19 - problems changing IP config
 

I feel rather stupid now, but here goes:-)
Currently did a fresh install of Fedora 19 gnome spin. I'm trying to change the IP configuration for IPv4 on wire. I've managed to enter the new IP information, but the apply button is grayed out. How can I actually save my new IP config? Please help.

andy just a thought. I can't try this out here. Is the user classed as an administrator?

My logic is this: if this is a normal user then it may need privileges to make the change. If you are not prompted for an administrator password then you will not be able to apply your changes.

I normally set up my core user as adminstrator so these things are transparent to me. I just had a look on my F20 system and if I edit a network connection I am prompted to cancel or save

I'm not sure what you mean by "change the IP configuration for IPV4" but if "on wire" means an ethernet card then the simplest way I do these changes is to log in as root in a terminal, navigate to:
/etc/sysconfig/ifcf-eth0
(or whatever your ethernet is called) and enter the relevant configuration variable in the file, such as IPV4_FAILURE_FATAL=no or IPV6INIT=no or IPADDR=192.168.10.1 etc. The possible variables are listed in:
/usr/share/doc/initscripts-*/sysconfig.txt
though, as I understand it, this file is a little out of date which means that the very latest is in the source code, but I've never had to go there for my simple and ordinary purposes.
