Oh? And you wrote that manpage I suppose, and you don't make mistakes... You may be able to read it, knowing what you "intended" to write. But others aren't mind readers. But we can add 2+2 and get a quite precisely defined 4.0000000000. > By default, NM does not manage any interface configured in > /etc/network/interfaces.

I have had N-M tear down a well configured staticly defined eth0 on dozens of occasions, despite using the iface designation in my e-n-i's. Most recently on a stretch install on a rock64 I had to erect immutable attributes to resolv.conf after making it a real file, and e-n-i to make networking Just Work. It may not do it today, things do get improved but my linux experience dates to RH5.0 and 1998 and its been something I've had to edit e-n-i and then quickly make it immutable, ditto for making /etc/resolv.conf a real file and immutable ever since N-M was made virtually mandatory. My networking is not portable and with the exception of my ancient lappy will never be. Theres a reason my /etc/hosts files are 20+ lines long, and my resolv.conf has a "search hosts nameserver" line in it, which N-M always removes if it can. The real file, made immutable fixes that too N-M is helpless when there is not a dhcp server or a dhcp server that only recognizes the MAC of one machine for security reasons. Based on my experience at making N-M work, you might want to get a shorter horse. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
