Hi everyone,
Fedora 20 here. I'm learning my way through nmcli and I'm having a hard
time trying to change an existing ip address (non-interactive way):
nmcli con mod my-con-em1 ipv4.addresses 192.168.200.101/24 192.168.101.1
The problem is that it's not *modifying* the ip. It is actually
*adding* it to the existing connection. Is this a bug or am I missing
something?
As I alluded to in my other mail, at the moment NM doesn't implement
direct changing of the interface's addresses/routes with immediate
effect. At this time you have to reconnect the interface with your new
changes for them to take effect. So for example:
nmcli con mod my-con-em1 ipv4.addresses 192.168.200.101/24 192.168.101.1
nmcli dev disconnect em1
nmcli con up my-con-em1
and em1 would have the new address.
In the future we will add the ability to change addresses/routes and
other properties on-the-fly like you are trying to do here.

I know there are alternate ways (GUI version, edit ifcfg* file, nmcli
interactive way)...just want to know what I'm doing wrong on the above
command.
BTW, playing with the above issue..I tried this one:
nmcli con mod my-con-em1 ipv4.addresses " "
...in order to see if I could empty out all existing IP addresses and
got nmcli to crash:
** (process:16190): CRITICAL **: nmc_parse_and_build_ip4_address:
assertion 'ip_str != NULL' failed
Segmentation fault (core dumped)
100% reproducible. Don't know if it's a known issue. If not please let
me know so I can open a bugzilla.
Thanks!
Jorge
