`ifcfg-*` files now allow you to specify a third DNS server `ifcfg-*` configuration files now support the "DNS3" option. You can use this option to specify a third Domain Name Server (DNS) address to be used in `/etc/resolv.conf`, instead of the previous maximum of two DNS servers.

(In reply to mpathan from comment #3) > Can we make this bug public ? customer is requesting for public access . > > -mpathan I am fine with that. Also if you don't want any networking daemon running on background I think that NM now has some set&exit mode.

Comment 7 Lukáš Nykrýn 2016-07-28 15:08:37 UTC
As I wrote in comment #1 I am sorry, but we don't accept any new features to initscripts. Please try NetworkManager instead and file any RFE there.

The attached patch is just for reference. Maybe other people have similar issues and the patch could help them.

Hello everybody, I'm reopening this BZ so it is reconsidered as a valid request for enhancement for initscripts package. IMHO, even though the 'initscripts/network-scripts' are in "deprecated" state, I think this request is reasonable enough to at least try to implement this change. However, I can only suggest to add support for 'DNS3' option, because glibc's MAXNS value is still (even in Fedora) set to value *3*, meaning that only 3 nameservers will be actually used for name resolving. ATM I don't see a valid reason to support DNS4 (or more) in network-scripts, especially when network-scripts are already in "deprecated" state, and they were never meant to be 1:1 equivalent to NetworkManager in the first place. (NetworkManager is suppose to replace and surpass the limitations of network-scripts.) Best regards, -- David --
