I've just looked at bug report #985755 and there are, currently, a mere four occurrences of the string 8723, only one of which is actually in the text. Most of the logs appear to be about the Intel PRO/Wireless 2200BG device, its module ipw2200 and firmware ipw2200-bss.fw. My newly oldest computer, an Acer TravelMate 3201XCi, built in 2004, contains one of these. If it's of any use to Charles, I can warn that this laptop has the annoying habit of booting up with the wifi blocked. (It has a pair of insanely placed toggling buttons/lights for wifi and bluetooth, and I've never figured out what the wifi light correlates with.) I know nothing about the R51 and whether there are any firmware buttons or function keys that would affect its wifi. As far as "my advice" is concerned (which really arose from an apparent difference in how the d-i firmware is loaded in wheezy and buster), we haven't yet been shown any direct evidence of which module drives the 8723, nor of what firmware it uses. (These can easily be determined from dmesg when the installed system is running.) This should allow a more focussed report from the installation logs (of which we've seen nothing IIRC). Cheers, David.

Hmmm... I am curious why they have eight 'A' records in the same subnet. Are they attempting to provide redundancy, load balancing, or something else? Figuring out how every client OS's and every client application will respond to this situation would require a lot of knowledge that is constantly changing -- e.g. a recipe for infinite bug propagation. This could be a source of your problems. (I would think they would be better off with one 'A' record pointing at a load balancer that fronts a DMZ containing the eight servers. A second load balancer can be added with suitable tricks to deal with one balancer breaking.) While you have no control over the

Use the "ip" command on each laptop to see which IP addresses do they have. If addresses are ok, then use "ping" to see if laptops are able to "see" each other. Then run server software on one of them (apache web server or nginx for example) and try to open it from another laptop using browser and http://[laptop_ip] URL. After that, you can play with other server software (like OpenSSH which can also be installed with tasksel) and "ssh" from one PC to another. Then you can try to configure firewall (using iptables or nft): "linux network administrator guide" can be used to study iptables. Or study how DNS works (See "DNS and BIND" book) As MTA (electronic mail) I prefer Postfix (which is available in Debian) and the book named "The Book of Postfix". These are "core" services each network administrator must know. But there are alot of other services like samba, ftp, databases, etc

Well, that depends entirely on what tests you performed, and what applications you're using (the real reason why you were testing these things in the first place). A typical test would involve you running shell commands to perform name lookups. Each of those commands would invoke a new process, which would re-read nsswitch.conf and resolv.conf and so on. In that sense, there is nothing you need to "restart". The restarting is implicit in the fact that you are running shell commands, each one containing a separate, standalone instance of the resolver. If there is an already-running process that you were using to do real-life stuff (e.g. a web browser), and you wanted to load a new page in the already-running instance of your web browser, then the web browser, which has its own separate, standalone instance of the resolver (possibly even a *unique* resolver, because browsers are special snowflakes), may have cached some information, such as the contents of resolv.conf. Thus, you would be well-advised to restart any running browsers, mail transport agents, NFS servers, and so on. Any or all of these programs that use DNS results may have cached the old resolv.conf, or the old results from DNS (positive and negative), or all of the above. But it all starts with an actual testing methodology of some kind, and the transparent reporting of your testing results. "I didn't notice any difference" is not that.

Take care with your terminology (unless this was some sort of joke). The idea of buying a router is to *avoid* having to set up an ad-hoc network. Routers are designed to be APs and run a DHCP server OOTB, whereas laptops are not. The debian-installer is designed to make connecting to such an AP very straightforward. (Of course, this might be all too conventional.) Cheers, David.

You can use the command pstops to print a PostScript file with space added to one margin and subtracted from the opposite margin. For example, pstops "1:0@1.0(1.4cm,0.0cm)" file.ps | lpr will print file.ps with 1.4 centimeters added to the left margin. Insert a negative sign to shift the other way.

Even using root hints as a DNS server source should not introduce a noticeable delay, whereas a client trying its number one DNS server and getting no reply will cause a delay of 5-30 seconds. Once the client has given up and found a working DNS server, it will normally stick with that one for a while, maybe half an hour, before retrying the first. Also, repeated calls to the same URL will normally get their IP address information from the client's cache, further confusing attempts at troubleshooting. It is usually possible to override a poor choice coming from a DHCP server, client computers have a DHCP client which can be configured to either accept or refuse the values provided by the server. I'm not sure how Network Manager deals with this, as I only use it on my mobile computers, and not on my main network machines. Besides, I control the DNS and DHCP servers in my network, and they do as they are told, something that an ISP-supplied router usually doesn't. To be fair, the ISP is only trying to cut down on finger-trouble service calls. -- Joe

I tried removing the 192.168.0.1 line along with the "search telus" line. I didn't notice any difference, but could this be because this stuff is buffered somewhere? Perhaps I need to kick something to make sure the new file is read. On Wed Mar 24 13:08:25 2021 Darac Marjal wrote: > Do you have an IPv6 address?

Re: WiFi Hardware not detected, during Debian NetInst Install
Hi. I saw the bug report. Mr. Charles Curley provided relevant information about the installation process stored on log files. Perhaps it would be good to follow Mr. David Wright's advice, you could help with bug-fixing process sending some installation log information to narrow what the developers should be looking for. As for the reproduction of the bug, I think one would need a similar hardware configuration to reach the problem; at least you need the WiFi device, so it would be good if you could provide more details, if you have the time, of course. Have a good day.

The path to the current (icon) directory is listed above the icons you

Well, I'm not pretty sure about this subject but... When I was setting up an OpenWRT router I saw there was a thing called "local domain", it looks like the router had a DNS that answered queries for that local top level domain, which had the hostnames of the devices connected to the router as subdomains. So, for example, if you had a device called "my-pc" and your local TLD was "telus", the writing "my-pc.telus" would send a DNS query to the router and it will answer with the IP address of that device. The router indeed used the DHCP to broadcast that local domain. In order for that local domain to work, the router needed to have a DNS server running and configured to answer such queries, the DHCP server had to pass the device's hostnames to the DNS someway, and the router had to be announced as a DNS server to the devices connected on LAN by DHCP. If you override the router DNS, the local domain will not work. Perhaps the router's DNS server redirects non-local queries to upstream servers and maybe those DNS servers broadcasted by the DHCP are a little slow; together, that could introduce a little delay for DNS responses. If you can, you could try to make the router send a known fast DNS server as the first DNS and then itself as the second DNS (if you want to keep the local domain). As I said, I don't know too much about this, so please correct me if I'm wrong.

It works well, but at home it takes 20 or 30 seconds to connect to my NNTP server, newsguy.com. If I take my laptop to the office and run slrnpull there, it connects instantly. I've mentioned this to people in the past, and the consensus seems to be that it's some sort of DNS problem. My laptop is running NetworkManager. When I wake it up at a new location, resolv.conf (which is actually a link to /run/NetworkManager/resolv.conf) gets overwritten with information that works where I now am. At the office, it's simply: # Generated by NetworkManager nameserver 192.168.1.5 nameserver 192.168.1.1 while at home it becomes more intricate: # Generated by NetworkManager search telus nameserver 192.168.0.1 nameserver 75.153.171.122 nameserver 2001:568:ff09:10a::56 # NOTE: the libc resolver may not support more than 3 nameservers. # The nameservers listed below may not be recognized. nameserver 2001:568:ff09:10b::122 My home router (supplied by Telus, notice the "search" line) shows two DNS addresses - 75.153.176.1 and 75.153.171.122 - on its configuration screen. The second address (but not the first) winds up in resolv.conf. The router is at 192.168.0.1. Dunno about those IPv6 addresses; I've made no conscious effort to use IPv6 anywhere. I suspect there's something fishy about that home resolv.conf; can one of you gurus suggest what it might be? Please run the following commands when your computer is connected to a given network: $ cat /etc/debian_version $ uname -a $ nmcli g status $ nmcli c show $ nmcli d show $ time host -v -t A www.debian.org 208.67.222.222 $ nmcli d show | perl -ae 'print $F[1],"\n" if $F[0] =~ /IP\d\.DNS\[\d+\]/' | xargs -n 1 host -v -t A www.debian.org The second to last command uses opendns.org's primary DNS server. The last command uses whatever DNS servers Network Manager is currently using. David

For the record, many modern routers provide a URL to reach the admin page, so as long as wifi and DHCP are enabled out of the box, and they all do that, there's no need to mess about with IP addresses and cabling at all. After all, many computer-like toys don't have Ethernet ports or USB-A sockets. Even many otherwise serious netbooks don't have Ethernet, a couple of years ago I bought one of the very few that did. There's probably none now. Domestic users all want to use wifi, none of these nasty cables, and I'm sure their governments also want them to do so. -- Joe

Activar / desactivar WOR (wake on ring) desde Linux
Hola, Estoy buscando la forma de activar / desactivar la funcionalidad de la BIOS WOR (Wake-On-Ring) pero desde el sistema, es decir, algo similar a lo que permite la herramienta ethtool¹ («ethtool -s wol d») pero para el puerto RS-232. Con la BIOS actual WOR se encuentra habilitado y funciona, pero quiero desactivarlo y no existe una opción para poder hacerlo (es una BIOS Phoenix del año 2005-2006). Tampoco quiero abrir el equipo para meter un jumper cada vez que quiera activar/desactivar WOR, que seguramente también sea posible pero me parece exagerado. He mirado la utilidad setserial² pero no veo que tenga disponible esa opción, por lo que si alguien tiene alguna idea o conoce de aplicación o forma de poder gestionar esa característica se agradecen sugerencias. ¹https://manpages.debian.org/buster/ethtool/ethtool.8.en.html ²https://manpages.debian.org/buster/setserial/setserial.8.en.html Saludos, -- Camaleón

Re: Debian et DNSSEC

Par défaut, une machine Debian sous Buster ou Bullseye, est-elle configurée pour utiliser DNSSEC plutôt que DNS ? Non. DNSSEC est du DNS, les entrées étant simplement valider par le propriétaire. 2. Qu'implique en terme d'administration, l'utilisation de DNSSEC ? Faut-il gérer ou renouveler soi-même des certificats ? Pas des certificats, signer les enregistrements DNS Voit-on du traffic TCP/53 à la place d'UDP/53 ? Aucun lien avec DNSSEC 3. Les opérateurs des serveurs DNS 1.1.1.1, 8.8.8.8, ... supportent-ils aussi le DNSSEC ? Oui Ceux-ci incitent-ils à l'utilisation d'une variante particulière (DNS over TLS, DNS over HTTPS, ...). 4.

Debian et DNSSEC
Bonjour, En installant Bind9 sur une machine, j'ai lu plusieurs références à DNSSEC, sujet que je connais très mal. 1. Par défaut, une machine Debian sous Buster ou Bullseye, est-elle configurée pour utiliser DNSSEC plutôt que DNS ? 2. Qu'implique en terme d'administration, l'utilisation de DNSSEC ? Faut-il gérer ou renouveler soi-même des certificats ? Voit-on du traffic TCP/53 à la place d'UDP/53 ? 3. Les opérateurs des serveurs DNS 1.1.1.1, 8.8.8.8, ... supportent-ils aussi le DNSSEC ? Ceux-ci incitent-ils à l'utilisation d'une variante particulière (DNS over TLS, DNS over HTTPS, ...). 4. En 2021, cela vaut-il le coup d'investir du temps et des moyens de "passer ses équipements" (serveurs, terminaux, routeurs,...) au DNSSEC ? 5. Conseils ? Suggestions ? Slts

Configuration de Bind9
Bonjour,
Je souhaite mettre en place un serveur Bind9 avec les points suivants:
La machine qui héberge Bind9 est sous Buster.
Elle possède deux interfaces Ethernet, chacune connectée à un réseau local
(foo.lan et bar.lan).
Elle est client DHCP sur un réseau local (foo.lan), et fait office de
passerelle sur l'autre réseau (bar.lan).
Le services DNS est réservé au réseau local pour lequelle la machine fait
office de passerelle (bar.lan).
Je souhaite que le serveur DNS puisse:
résoudre quelques noms d'hôtes locaux (toto.bar.lan, www.bar.lan)
résoudre par un moyen idoine (redirection ? récursion ? transfert ? ...)
quelques noms d'hôtes sur l'autre réseau (pipo.foo.lan, www.foo.lan)
réduire au maximum les temps de réponses aux requêtes DNS (cache, ...).
Le serveur DNS/DHCP/GW sur foo.lan est un EdgeRouter d'Ubiquiti dont je ne
maîtrise pas (encore) les moyens de debug.
Voici quelques éléments de ma config
zone "bar.lan" {
type master;
file "/etc/bind/db.bar.lan";
forwarders { 192.168.1.1; }; # Adresse du serveur DNS sur foo.lan
};
resolv.conf:
nameserver 192.168.1.1
search foo.lan
Une résolution depuis un PC sur bar.lan fonctionne avec host1.bar.lan mais
ne fonctionne pas avec host2.foo.lan.
J'observe que dans ce dernier cas, Bind9:
- reçoit une requête sur host2.foo.lan puis sur host2.foo.lan.bar.lan
- répond No such name à chaque fois
- me semble ne relayer aucune requête vers le serveur en 192.168.1.1 avant
de répondre mais relaie la requête vers un serveur DNS public

Is it likely to work? If I understand your description correctly, the RAID6 was the only redundancy in the system. That being the case, you will not be able to have LVM assemble the VG, and you will not be able to mount the ext3fs. You can try forensic recovery with PhotoRec https://www.cgsecurity.org/wiki/PhotoRec or ddrescue: https://www.gnu.org/software/ddrescue/ But I would bet on getting anything much off of those disks. Next time: verify that you are backing up everything that you need to backup. I know it's boring. -dsr-

You can use DNS Benchmark by Steve Gibson, written like 20 years ago in assembly language. This will test your various DNS configurations and diagnose them: https://www.grc.com/dns/benchmark.htm Use Wine to run it. wine DNSBench.exe It will tell you what's wrong, if anything, with your DNS configuration.

Replace a failed block device with null PV in an LVM VG
Hello, At work, there is a fileserver with a failed external drive enclosure. I am attempting to recover some data that is probably not on the failed drives. This file server started out with 36 internal drives (in three RAID-6 arrays) that formed the initial 3 physical volumes to an LVM volume group. In that LVM I created 16 of logical volumes (all where 5Tb in size), formatted each with ext4, and stored a huge number of smallish files. That was about 9 years ago. Over the years, as more disc space was needed, 5 external RAID drive enclosures where added of varying capacity between 30 and 90Tb. Each was added to the LVM VG as another physical volume, and the existing logical volumes where expanded to fill the additional available space, and the ext4 filesystems where resized to use the expanded volumes till they where each 15Tb in size. Now one of those external drive enclosures with 42Tb of capacity has failed. The data centre technician tells me that it has 28 drive bays, and 15 of those drives are flashing angry red lights, so recovery is unlikely Most of the data on that file server is already backed up elsewhere, but I have been told that there are about 50,000 files that where somehow not backed up, and could I try to get them back. The missing files are the oldest, and would have been on the original good drives, but I can't mount the ext4 filesystems because the LVM cannot assemble the VG because one of the physical volumes is missing. Is there a way to assemble the VG and mount those ext4 filesystems in such a way that read attempts from the missing PV will return zeros, but the rest of the filesystem will work? Perhaps by creating a virtual block device with the correct capacity and UUID, or by special LVM commands? How will ext4 behave if some parts of it's underlying block device return zeros on read? I know that this is a last ditch data recovery effort. Is it likely to work? -- David Pottage

This line looks a bit suspicious to me. The "search" line is _supposed_ to be a list of domains which your computer is part of. It's implemented such that, when the resolver is asked to look up a short name (e.g. "printer" or "my-laptop" etc), then each item in the search list will be appended in turn and a lookup made. So, for example you could have "search example.com example.net" and a lookup for "gateway" would try "gateway.example.com" then "gateway.example.net" in turn. According to IANA, who keep the register of top level domains at https://www.iana.org/domains/root/db, there is no such domain called "telus", so one would expect a lookup for "gateway.telus" to fail (unless it's a private domain, only hosted on the telus DNS servers. That's perfectly possible). > shows two DNS addresses - 75.153.176.1 and 75.153.171.122 - > on its configuration screen. The second address (but not the > first) winds up in resolv.conf.

If you run "ip -c -6 a", do you have an address with "scope global"? You may have one with "scope link", but that won't help at the moment. If you do, then congratulations: Telus have provided you with a connection to the modern internet. If not, then you won't be able to reach these resolver addresses. > > I suspect there's something fishy about that home resolv.conf; > can one of you gurus suggest what it might be? > OpenPGP_signature Description: OpenPGP digital signature

It should be relatively easy to do so if some packages are only recommended instead of depended on. Does 'apt install --no-install-recommends' want to install significantly less packages?

I do not know if running Qemu immplies that a X11 server is running or simply installed - the Qemu package in Debian is an all-architectures one: if you want to emulate/virtualize only X86/X86_64 hardware, qemu-systemx-86 is sufficient - if you do not want to install X11 and can not avoid it with Qemu, perhaps you could look at Xen. I do not know if it could be of interest in your case. My opinion (but I am not knowledgeable on this) is that Xen is perhaps more modular than Qemu but with an added (to me at least) complexity. Another element: I seem to recall that Xen is welle used/known is the NetBSD world and that could translate in your FreeBSD approach? https://www.linux-kvm.org/page/Virtio This is also confusing, as the document is written about kvm but cites qemu as an example. see above :-)

The 20-30 seconds hint at a DNS timeout. Try removing your first entry (192.168.0.1) from resolv.conf and see whether this changes (don't restart, NM will clobber your changes!) Of course, the above isn't a permanent solution, just a first troubleshooting step. If it doesn't help, we've got to look elsewhere. If it helps, that means that your home router (presumably that 192.168.0.1) is announcing itself as a DNS but isn't up to the task and doesn't answer queries. That means that you either convince it to do its job properly, or you convince your NM to ignore it as a DNS (for NM I can't help you: I dislike that guy :) Cheers - t > > -- > cgi...@surfnaked.ca (Charlie Gibbs) > signature.asc Description: Digital signature

I suspect there's something fishy about that home resolv.conf; can one of you gurus suggest what it might be? Some hints as I'm not that savvy in DNS. The first line in the resolv.conf is a private ipv4 and I would assume that your dns queries are first going there then would fallback to the public addresses incase of failure. Any chance you can bypass your ISP router (bridge mode/using your own router)? If yes, this would tell you if the ISP router is at fault. 'dig' could help you there as well.
