For what it's worth, you're trying two mutually exclusive commands, as far as I can see. NetworkManager automatically configures things as instructed by a DHCP server, or self-configures a link-local address, or activates a chosen user-configured network setting (the later may be an option for you, but you wanted to do stuff by the command line interface, and I'm unfamiliar with controlling NetworkManager that way). I've certainly made new custom settings in the NetworkManager GUI, and chosen them to force manual changes to my network. Using an IP command temporarily changes the current operating parameters, but doesn't change any stored configuration. NetworkManager's next operation will do what it wants to do, again. Overriding what you may have temporarily changed. I would have thought that if you were making temporary changes, this wouldn't have mattered. But it sounds like you want to make permanent changes, despite initially talking about making temporary ones, and going about it the wrong way. -- tim@localhost ~]$ uname -rsvp Linux 3.19.8-100.fc20.i686 #1 SMP Tue May 12 17:42:35 UTC 2015 i686 All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I will only read messages posted to the public lists.
