Where it is not available, its a pain in the ass because even if you set it up as a static ipv4, N-M will tear it down in 5 minutes or less. And N-M is a dependency because most have a dhcpd running, probably in the router by default. You are determined to exterminate any and all users of a hosts file, staticly defined network. Its ideal for small home networks. The SOB (N-M) ignores the word static in the stretch version, so I'm back to a decade ago when N-M was new. Doing my config file edits quickly, because when you save it, the next thing you'd better to is a root chattr +i to that file, then go on to nuking the /etc/resolv.conf link and make a real file that only has 2 lines, the first defining the nameservers address, the 2nd saying dnssearch hosts, nameserver. Save it and weld it down with a root chattr +i so N-M can't screw with it. And since stretch, if theres even a hint of a sniff of ipv6 being setup, the net tools will NOT assign a route/gateway to the ipv4 config. So your hosts file entries all work, but ping yahoo.com. network unreachable. /ipv6 rant. > > Rants aren't so bad, it's when they are utterly clueless and devoid > of factual content one could tend to come off looking like an > absolute lunatic.

I'd love to file bugs, but I only have one email address. And nominally 80 milliseconds after I enter it in an account form, "its already taken". So I can't file the bug without logging in, and I can't login because it heard of gheskett@shentel.net back in 2015 according o my records in FF. And the username I used then now contains an illegal character. I guess somebody changed the rules for usernames? It is for sure, one way to cut down on the bug reports isn't it? > Andy Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
