15.1, but yes, that is what I did and it worked, as I posted a moment ago. No, reboot was not necessary. But I have no idea what it changed that worked, nor what caused the problem. -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)

The reason I asked if it was 15.2 is that I got surprised by that @localhost machine name in a fresh install of 15.2, where we instead used to get a random string of characters as the initial hostname in 15.1 and previous versions.

Ah, yes, you are right, I saw it on a new install of 15.2. But this machine is old. It had the correct name and suddenly it changed. -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)

No, this entry breaks postfix. Well... I haven't tried that exact entry, but the one that YaST created in the past: 127.0.0.2 Telcontar.valinor Telcontar The error caused was "fatal: parameter inet_interfaces: no local interface found for 127.0.0.2" Although I have a note from 20180825 that maybe the error was solved. Previous to that date, I had an email exchange with postfix developer where he said it was not postfix fault. Adding a fourth field is not in my documentation :-?

Right.

Read that (and linked) a bit, Wietse's (Postfix's) view seems quite sane. And Yast-genreated /etc/hosts files have been broken as such since at least, IIRC, S.u.S.E 5.3 (or always). No idea why that's never been fixed (or even filed as a bug (by anyone, including esp. me *sigh*)).

==== -A, --address=/<domain>[/<domain>...]/[<ipaddr>] # ^ note that the second '/' # is not optional here, but # the IP is
Ah.
That's tricky. From reading the manpage, it looks as if you can use: address=/example.com/example.org/[<ipaddr>] Hm. Let's just try: $ host example.com example.com has address 93.184.216.34 example.com has IPv6 address 2606:2800:220:1:248:1893:25c8:1946 example.com mail is handled by 0 . $ host example.org [same] $ host example.net [same] [adding address=/example.com/example.org/example.net/127.128.129.130 to dnsmasq config & restarting dnsmasq] $ host example.net example.net has address 127.128.129.130 $ host example.org example.org has address 127.128.129.130 $ host example.com example.com has address 127.128.129.130 [editing to address=/example.com/example.org/example.net/ (note again the trailing '/'!) & restart] $ host example.com Host example.com not found: 3(NXDOMAIN) $ host example.org Host example.org not found: 3(NXDOMAIN) $ host example.net Host example.net not found: 3(NXDOMAIN) Way cool! :) Now that weird syntax makes sense, but the lonely '/' before the optional <ipaddr> is quite easy to overlook inbetween those brackets '[..]/[..]'... But, it's correct :) It might be easier to see, but differently irritating on the syntax if written as: -A, --address=[/<domain>...]/<domain>/[<ipaddr>] but the ending '/' might not quite as easily be overlooked. Writing correct and understandable documentation for syntax like this is _HARD_. Examples can help (but not always!). Using: address=/example.com/example.org/example.net/<ipaddr> to point the example domains to a local webswerver might actually make sense, esp. in a larger organization :)
As for domain answer, so --address=/example.com/ is equivalent to all its subdomains. ^^^ [..] ^^^^^^^^^^^^^^^^^^ Note that NULL addresses normally work in the same way as localhost, so beware that clients looking up these names are likely to end up talking to themselves. ====
The last means: don't use '0.0.0.0' or '::' as addresses (in dnsmasq NOR in /etc/hosts).
Ok, nice to have a translation :-)
You're welcome :) That's another thing you _often_ see: using the NULL address in /etc/hosts or whatnot, which usually is just wrong. But again, my main point was that dnsmasq takes _all subdomains_ of a domain... Continuing above example: $ host www.example.net 1.1.1.1 [..] www.example.net has address 93.184.216.34 $ host foo.bar.example.net 1.1.1.1 Using domain server: Name: 1.1.1.1 Address: 1.1.1.1#53 Aliases: Host foo.bar.example.net not found: 3(NXDOMAIN) $ host www.example.net Host www.example.net not found: 3(NXDOMAIN) $ host foo.bar.example.net Host foo.bar.example.net not found: 3(NXDOMAIN)
In a seperate file in /etc/dnsmasq.d/, which is included from /etc/dnsmasq.conf: $ host track.adform.net Host track.adform.net not found: 3(NXDOMAIN) $ host track.adform.net 1.1.1.1 Name: 1.1.1.1 Address: 1.1.1.1#53 Aliases:

Interesting :-)
Does somebody publish lists of such "bad" domains, separated by purposes, like tracking, in ready syntax?
https://pgl.yoyo.org/adservers/serverlist.php?hostformat=hosts&showintro=1&mimetype=plaintext
In /etc/hosts syntax.
Thanks. But that one misses the "separated by purposes", or commenting what does each address there.
you didn't ask, but ... and you will not spend enough time to peruse what you request. there are limits.
I can not block that many hosts without knowing what they are for. I did ask for purpose separation.
to to the site, pgl.yoyo.org and see what he offers. I only provided the line to the text list for addition to /etc/hosts. use your time instead of mine. I have many other non-essential tasks to waste time on.
You could simply have pointed from the start to the information page, but I'm just commenting on why I do not like lists like that one, not asking you to do the job of creating one.

Patrick, you should have read the mail you answered to, a format for 'dnsmasq' was asked about! And, lo and behold, that site _does_ offer such a formatting, albeit one, that has to be massaged, but in both cases, it's easy: https://pgl.yoyo.org/adservers/serverlist.php?hostformat=dnsmasq-server&mimetype=plaintext -> sed 's/^server=/address=/' https://pgl.yoyo.org/adservers/serverlist.php?hostformat=dnsmasq&mimetype=plaintext -> sed 's@/127.0.0.1$@@' (automating this via curl/wget | sed > /etc/dnsmasq.d/blocklist-yoyo.conf and cron is trivial and left as an exercise to the reader ;) The point about the purpose of entries remains. Hm. Maybe ask pgl.yoyo.org about providing the 'address=/domain/' format directly? Me? I prefer to manage my blocklist(s) manually, with dnsmasq's ability to make whole domains NXDOMAIN and not just single hosts as with /etc/hosts, it's quite manageable and the sites I visit tend to use all the same adservers/unwanted hosts anyway. And using iptables/nftables for such purposes would be just stupid (as hostnames get resolved at startup / insertion of the rule, and e.g. for the mentioned track.adform.net only one of 8 IPs would be blocked, at least with iptables! (just talking IPv4 here)). Well, Carlos, you've got the choice ;) -dnh -- / "You know how cats always land on their feet when they fall \ [ from a sufficient height?

Yes.

How do you find the names of those pesky sites? Wondering aloud. Those lists at yoyo are huge, I doubt I really want to block all of them. Perhaps I would prefer a limited list such as what some blockers call "intrusive advertising". I do not want to block all adverts, only those that, for example, create a floating banner that makes reading difficult. After all, sites have to make a living.
And using iptables/nftables for such purposes would be just stupid (as hostnames get resolved at startup / insertion of the rule, and e.g. for the mentioned track.adform.net only one of 8 IPs would be blocked, at least with iptables! (just talking IPv4 here)).
Right.
Well, Carlos, you've got the choice ;)
It is one of those things in the back of my mind, not top priority :-) ublock does a good job, considering. Then, for example, let's say that I do want to open facebook one day I do rarely, but I do. I dedicate a separate Firefox profile to it, so that they can not relate my identity to all my browsing. Similarly I have another for Amazon. This means I can not block the entire amazon domain at the dns level. -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)

IPv6 was integrated/implemented quite a while before that - starting 2006, I was using an ipv6 tunnel - I don't know what that corresponds to in terms of SUSE/openSUSE releases, maybe 10.0 ? I think(!) the /etc/hosts used to be "127.0.0.2 linux.site linux" (I see it mentioned in several places on the net) I also see it mentioned way earlier, on the suse-linux-e lists in 2001, but unfortunately the archive is gone. I don't quite get why 127.0.0.2 should be a topic now, almost twenty years later :-)

TBH, I don't see much description other than people talking about what it _might_ be used for. I use a few 127.x.x.x addresses myself, 127.0.0.1, 127.0.0.36, 127.0.0.99 and 127.0.0.111, for instance.

Many programs expected local host name to resolve to IP address and misbehaved when this failed. So host name was assigned to 127.0.0.2 to make it always resolvable and independent of dynamic real IP address. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I first read about IPv6 in the April 1995 issue of Byte magazine. I've been running it since May 2010. Also, I could never understand why an entire class A address block was assigned to loopback.

The crux I got from the link was that 127.0.0.2 was implementation defined (by the various distros) to behave as they needed it to. So there wasn't any one thing that that address did on its own. (it could have been any 127.0.0 address, but I guess the next after .1 was what most used when they used it) -- David C.
