Description Frank Griffin 2012-12-13 16:29:43 CET 
Supposedly, you can override NM's default use of dhclient as a DHCP client by specifying "dhcp=dhcpcd" in the [main] section of Networkmanager.conf.

However, if you do this on a system whose wireless is working with NM/dhclient, NM is suddenly unable to connect, giving the following:

In other words, everything works perfectly except the invocation of dhcpcd.

This is particularly annoying because at the moment our dhclient does not support the DHCP domain-search option, while dhcpcd does.

Comment 1 Marja Van Waes 2015-04-16 22:31:32 CEST 
Sorry, but this bug saw no action since over 2 yrs ago - no cauldron package has stayed the same - and is still assigned to Bug Squad.

Closing as OLD

Please reopen if this report is still valid for _current_ cauldron and/or fully
updated Mageia 4

Status: NEW => RESOLVED
Resolution: (none) => OLD

Comment 2 Frank Griffin 2015-04-20 00:43:56 CEST 
Yes, this has become moot, as dhclient now supports domain-search.  I suspect this had to do with clashes between NM and ifcfg back in the days when I used the RedHat script in addition to NM.
