Debian en HP Envy
Saludos a todos. He heredado una HP Envy con I7 SSD y varios chiches más, gracias a que al dueño se le quebró parte del monitor y ya no la quiere. En fin, la consulta es la siguiente: estuve buscando en la web qué tal va la compatibilidad con debian (es el SO que uso hace años y no quisiera cambiarme) y encontré muy poco. Lo que leí es que con Arch va bien. La probé con un live cd de Ubuntu y funciona. Alguien tiene Debian instalado en alguna máquina similar? Me serviría mucho si pueden orientarme. Muchas gracias. -- Martín Ayos === https://ayos.com.ar Linux User # 481475 === "Caute" ===

Hallå, Någon som är duktig på filsystem här? Efter 13 år är det dags för ny dator -- stationär dator i 'hemmakontoret'. Den gamla jobbar på bra så jag unnar mig lyxen att inte hasta med den nya.

I tried this line too, unforutately it does not work either.
I mean after executing the config file with this line it shows itself in
output of command 'nft list ruleset' but I still can not connect to
internet from my phone.
I tried many lines similar to this, none works:
ip saddr 192.168.231.3/24 ip daddr != 192.168.231.3/24 masquerade
ip saddr 192.168.231.0/24 ip daddr != 192.168.231.0/24 masquerade
ip saddr 192.168.231.0/24 oifname "wlxe8de27a5ab1c" masquerade
oifname "wlxe8de27a5ab1c" masquerade
I also noticed in output of 'nft list ruleset' that other rules there are
using capitalized letter so i try it too:
istead of chain postrouting {
I used chain POSTROUTING {
I also tried to put this command in table that already exist instead of
creating new one (masqrule) - instead of running my whole script I run
only one command (after reboot so there are no more changes made by me before):
nft add rule ip nat POSTROUTING oifname wlxe8de27a5ab1c masquerade
(note that here I used 'ip nat' table that is added autmaticaly by
docker server i guess)
Since nothing I tried does work I guess my next step should be to see
where/how those packets from phone are handled. I guess program for that
is tcpdump which I have installed. But since I am unfamiliar with this tool
I would need help from mailing list to guide me what to look for and how
to use this tool.
So please can you give me some info what command should I use with
tcpdump to see where packets from phone are going - or why they do not
go where they should?
Just a reminder - I can connect from phone to my computers web server - which
I also installed just for debugging this. The problem is I can not connect from
phone to internet (let say google.com)

Sorry for long pause in reply (my hard disk was dieing so I replaced HD and
installed whole debian from scratch).
Now (after reinstall everything) I am the point where I want to make my
router to work. I set up dnsmasq to enable DHCP with line in config:
dhcp-range=192.168.231.241,192.168.231.254,12h
and reseted my WiFi router after little configuring with my phone I can
connect my phone to WiFi router and to my computer (that still has address
192.168.231.3). I can access http server on my computer when I type in my
phone address to connect in web browser: http://192.168.231.3/text.html
(I created on my computer file /var/www/html/test.html)
That is all without changing anything with nft program.
I created a file with exatly this content:
#!/usr/sbin/nft -f
table ip masqrule {}
flush table ip masqrule
table ip masqrule {
chain postrouting {
type nat hook postrouting priority srcnat; policy accept;
ip saddr 192.168.231.3/24 ip daddr != 192.168.231.3/24 masquerade
}
}
When I execute this file with sudo unfortunately nothing changes, I can
not connect to the internet (trying www.google.com from phone).
[[ this is about old system I had on old HD:
I remeber before reinstalling whole system at this point I had connection
from my phone to the internet (I could see google and then some videos on
youtube worked too on the phone) After I rebooted my old system I could not
connect to internet anymore from the phone. I slightly changed the script
from your post to current state (namely using ip allways instead of inet at
first two lines of script and using 'masqrule'as table name) I thing those
changes are ok.
]]
I have no idea what else should I try to make this work. Maybe I forgot
to issue some command (but I do not think so).
BTW putting above script into /etc/nftables.conf (at the bottom of file)
did not ever worked - I had always to run that file manualy as root.
Command 'nft list ruleset' only then showed this table.
I have no idea why. To me it seemed as if /etc/nftables.conf file
was not executed (I have rebooted many times so this file should run).

OH my god! Why did not I tought of just copying it before all this mess. I already managed to install debian from scratch and upgrade it to sid on new HD. Now I have to install all the programs i use. And that is the mess. because I have used debain since Sarge version and keep copying files and setups from old to new computer/HD whenever I upgraded hardware (I started with Pentium I - or whatever name was it then). So I have lot of programs and configuring files to deal with. This is also why my reply to this email is soo late (I have been configuring new system). And for now I have not installed many programs I need to new system so I use old system up to reply this email. So I will probably ask more questions later (especialy about setting up local wifi router - I have some problems with that - but I will leave it for little later). Thank you all for help provided so far. Martin

How to install Sid with non-free firmware for wifi?
Hello, I am currently using Sid version of Debian - in /etc/apt/sources.list i have: deb http://httpredir.debian.org/debian/ sid main contrib non-free non-free-firmware non-free and non-free-firmware I have because of drivers I need for my machine (most acute is wifi receiver, but i guess for sound and graphic too) Now my hard drive is dieing and I bought a new HD. I want to install debian on new HD to replace current one. I tryed many approaches but what looks like more strightforward is using installer from: https://cdimage.debian.org/cdimage/daily-builds/sid_d-i/arch-latest/amd64/iso-cd/debian-testing-amd64-netinst.iso This is net installer with all non-free firmware I guess. Ist size is 644M. The problem is that my wifi receiver is not recognized by installer. On my current computer it need some password to be supplied when starting computer (it is done in /etc/network/interfaces iface wlxe8de27a5ab1c inet dhcp wpa-ssid Thomson wpa-psk mypassword ) When I use installer CD I do see that lights on this wifi adapter does NOT blink at all (it stay off all the time). How do I get installer to make to recognize my wifi adapter? I have looked inside CD and it has all nonfree drivers I have installed on my computer instalation: firmware-linux-free firmware-amd-graphics firmware-atheros firmware-misc-nonfree firmware-realtek My wifi adapter is TP-LINK TL-WN722N Description of what happen when I start intaller CD: I start installer in Expert mode (somewhere i read it is needed to install Sid) All goes fine until installer try to detect network. It does not recognize my wifi adapter. It does some testing with ethernet adapter (enp3s0) then test for wifi searching DHCP and finds nothing (during this search I noticed that it does not use my wifi adapter - it does not blink at all). Then it offers me to enter values manualy but it uses those values with ethernet adapter. And I am stuck here: how do I recognize my wifi adapter? Martin

I did create FILE.conf and after executing it I can connect to internet from
my phone. THANK YOU!
Now where do I put this FILE.conf? I would like for it to run everytime
I turn on my computer. Is there some standard place for it - perhaps in
/etc directory? Maybe i should create some script in /etc/init.d/
directory?

You are right, it is enabled:

I did not had dig installed but host worked, alas it showed me that I do
not have installed DNS server. So I installed dnsmasq package and
wonders happened (without me editing any config files - just installing
dnsmasq) - on my mobile phone when I connected to 192.168.31.1 address
(default router address when I look from phone) It showed now green line
from router to internet.
But unfortunatelly phone does not connect to internet yet. I guess I will
need to issue some 'sudo route' command to add path from my router to
outside world (actually I do not have idea if this is the problem).
> Check that you do not have blocking rules in firewall
I do not use firewall anymore, since I stoped using wired home phone
(dialup modem) to connect to internet with ppp protocol. Since I am now
connected to internet via my weak antena which is connected to router(A)
and then to internet I know that distant router(A) is protected enough
(after all it uses only local address that i can see 192.168.0.1).

I did not add any masquerading rules by myself and output of command
'nft list ruleset' is showed below. It does not have anything like you
showed in section 'table ip sharedconnection'. I remember using iptables
command to make firewall and masquerading my computer while I was using
dialup modem internet connection. I do not set up use any iptable rules
manualy anymore.
So this is probably what I need to figure out how to use masquerading
and other firewall rules to enable my new router to connect to outside
internet. (I must admit that I forgot what rules should I use to enable
this setup - so I need your help)
Here is output of 'nft list ruleset' 'iptables -S' and 'iptables -L' command:
(I am not sure they provide different info, but here they are)
Thanks a lot

This is when I started looking at browser on the link https://lists.debian.org/debian-user/2023/10/threads.html but could not find my message there (note that it shows only first page of 2 pages of emails) I did not realize that this list have 2 pages, I always looked only on the first page. And so I tried to use my different email addresses that I had and post same message again few times. I also did not receive any message back from mailing list that i send (some of addresses were not subscribed to mailing list). Finaly I made a post from this address and got the message back as posted in mailing list.

But I really do need some advice about the problem I described in (lot of the) messages I posted. Martin
How do I connect my new wifi router (Mi Router 4C)?
Hello, With wifi antena I receive a (rather weak) signal that connect my computer to internet. I have to use windsurfer antena booster (http://members.multiweb.nl/schaaijw/windsurfer_wifi_en.pdf) to get usable signal. So my computer have internet signal from wifi antena - yay great thing :) Now I also want to connect to internet with my mobile phone! So I got a wifi router (Mi Router 4C made by Xiaomi) (web site https://www.mi.com/global/product/mi-router-4c/ documentation https://manuals.plus/_mi/mi-router-4c-manual) As it turn out I am not so bright to make this whole setup working :( I pluged in new router to power and connected ethernet cable from my computer to router WAN connection. (I belive this is how it should be connected togheder) >From now I had some partial successes and whole lot of problems. I will describe what I tried later, but I would like to ask you now How do I proceed from now on to set up router? I tried lot of setup and none worked.

So I choose to manualy set up 'Static address' for router as folows (my computer has IP address 192.168.231.3): IP address: 192.168.231.5 Subnet mask: 255.255.255.0 Default gateway: 192.168.231.3 DNS: 192.168.231.3 After all this setup I could issue those commands on my desktop: (this is my desktop IP address - just to show it works) boza@redmoon:~/work $ ping 192.168.231.3 PING 192.168.231.3 (192.168.231.3) 56(84) bytes of data. 64 bytes from 192.168.231.3: icmp_seq=1 ttl=64 time=0.074 ms 64 bytes from 192.168.231.3: icmp_seq=2 ttl=64 time=0.058 ms 64 bytes from 192.168.231.3: icmp_seq=3 ttl=64 time=0.058 ms 64 bytes from 192.168.231.3: icmp_seq=4 ttl=64 time=0.048 ms 64 bytes from 192.168.231.3: icmp_seq=5 ttl=64 time=0.058 ms 64 bytes from 192.168.231.3: icmp_seq=6 ttl=64 time=0.048 ms 64 bytes from 192.168.231.3: icmp_seq=7 ttl=64 time=0.058 ms ^C --- 192.168.231.3 ping statistics --- 7 packets transmitted, 7 received, 0% packet loss, time 6123ms rtt min/avg/max/mdev = 0.048/0.057/0.074/0.008 ms (this is new router IP address) boza@redmoon:~/work $ ping 192.168.231.5 PING 192.168.231.5 (192.168.231.5) 56(84) bytes of data. 64 bytes from 192.168.231.5: icmp_seq=1 ttl=64 time=0.445 ms 64 bytes from 192.168.231.5: icmp_seq=2 ttl=64 time=0.381 ms 64 bytes from 192.168.231.5: icmp_seq=3 ttl=64 time=0.384 ms 64 bytes from 192.168.231.5: icmp_seq=4 ttl=64 time=0.360 ms 64 bytes from 192.168.231.5: icmp_seq=5 ttl=64 time=0.376 ms 64 bytes from 192.168.231.5: icmp_seq=6 ttl=64 time=0.403 ms ^C --- 192.168.231.5 ping statistics --- 6 packets transmitted, 6 received, 0% packet loss, time 5107ms rtt min/avg/max/mdev = 0.360/0.391/0.445/0.027 ms So ping work as expected but when i look on my mobile phone and connect wirelesly to router and on phone I look with browser at address 192.168.31.1 (this is addres router is using when i look from phone) it show me that I can connet from mobile phone to router (with green line on the picture it shows) but I can not connect to internet (it shows red line from router to internet) I hope someone will be able to give me some hint how to solve this issue and be able to connect to internet from router - and connected phone.

Hello, I have set up 40 identical systems with Debian 12.0: same SBC, same OS version, same preseed file.

These 2 systems log continuously in Xorg.0.log filling up the hard drive at a rate of ~1MB/min. Please see attached file for an excerpt of the content dumped into Xorg.0.log. Can anyone help me understand what's happening and how to fix/prevent this? Do not hesitate to request additional information if that can help.

Re: Xfce destop environment
Hi William, xfce configuration files relevant to your user session are stored in your home dir. you can more or less just delete / move the config files and they should get recreated upon logging in to a xfce session. I searched on google for "reset xfce configuration" and found many posts like this: https://forums.linuxmint.com/viewtopic.php?t=122332 "Open a terminal, back up your current configuration: Code: Select all mv ~/.config/xfce4 ~/.config/xfce4.bak Then either leave it like that, which will reset to a default Xfce desktop (no Linux Mint customizations), or copy the skeleton files with the following command, which will reset to a default Linux Mint Xfce desktop: Code: Select all cp -r /etc/xdg/xfce4 ~/.config Then log out and log in again to effectuate the new configuration." I believe you good get results in such a way. It also might be just smth small which is broken. Could you describe "broken" some more? A panel might be hidden but u can access all xfce configuration panels by right clicking on the empty desktop open a menu, than applications follwed by settings. Also take a look at the xfce project documentation, it's quite large with many screenshots to demonstrate the principles of xfce https://docs.xfce.org/xfce/getting-started#the_desktop_environment Nearly everything is just a right click from configuration separated. You could also create a new user account with xfce configured as default session and copy your files over :) Good luck :) Cheers, Martin On 2023-01-30 19:57, William Torrez Corea wrote: On Mon, Jan 30, 2023 at 12:43 AM David wrote: On Mon, 2023-01-30 at 00:07 -0600, William Torrez Corea wrote: What happened with my desktop environment?

Re: freezing / unstable Debian Testing on MSI Stealth GS77 laptop
Hi JD, sorry to hear that you have these kind of troubles. I dont know much about this gpu/igpu setups, but I want to give some proceedings I would choose: You write that there dont seem to be any logs. Where did You look? I would expect, that there might me /var/log/syslog messages concerning kernel panics or maybe SystemD journal entries from that last boot (journalctl -b 1 or smth). What kind of logs did You check or are some logs Your google searches might have produced not there or empty? They might have to bee enabled. Also there might be error messages of the xserver /var/log/Xorg.0.log. On top I would take a look into the messages of my Xsession itself (~.xsession-errors) Many places to check, I'm afraid to say :) If You have another system You could ssh into Your crash prone laptop to get messages live. Posting some details about the versions of the nvidia modules and such might be useful. Some other readers might be able to compare such strings. And which CPU version does Your notebook have? (cat /proc/cpuinfo, maybe). If this is a CPU in a combo setup "some big/beefy cores and some lightweight/lowpower cores" it have implications w. applications in my opinion. And one thing I would like to recommend: try another, maybe more recent system. Boot from a ubuntu or fedora or some outher fresh distributions live iso and check / compare modules and configuration parameters and - if possible - behaviour of the particular applications. Good luck and please post log contents or snippes of logs, if You find some. Cheers, Martin On 2023-01-25 09:56, JD wrote: Hello, I'm trying to find some help in order to debug or resolve the issues I'm facing. Hopefully, someone will be able to help me here. The main problem that prevents me from trying to solve it myself is the absence of logs and messages. So, my laptop MSI Stealth GS77 with a Debian testing (up to date) installed on it can freeze when launching 3D programs (both with setting the nVidia card or the integrated Intel chipset). Once it also complained about missing SSD drive (nvme). I currently don't know if both could be related, but I'd say it's unlikely. Some information about my system: I installed Debian testing since latest Debian stable had many issues (no audio, not wifi, unstable 3D graphics...). Debian stable with backports didn't helped much (it fixed some issues but not all). Therefore, the most practicable is Debian testing. The issue I have is that seldom (but quite often), when running a 3D program, the OS is completely freezing. There is no way to retrieve any logs or information about the issue. The screen freezes, the keyboard doesn't respond. The only thing I can do is to use a long press on the power button to switch the laptop off (alt sys o doesn't work either). And on the next reboot, my filesystem fixes wrong inodes and therefore this is not possible to consultate any logs. I don't really like to say that, but the laptop works well on Windows 11 (no freeze, no crash, no nvme issues). Thus my belief that the issue is on the Linux side. More information: Desktop: XFCE nvidia: latest proprietary modules available on Debian. Also tested with modules directly provided by nVidia. 3D programs run on nVidia or the Intel chipset (with setting appropriately __NV_PRIME_RENDER_OFFLOAD and __GLX_VENDOR_LIBRARY_NAME).

For what it's worth; The revert as currently suggested also reverts big chunks for Intel and nvidia based GPUs, which unsurprisingly the maintainers of those aren't too thrilled about. And really i'd be amazed if it doesn't cause regressions for those systems...

There could be other issues lurking which would not get exposure and therefor wouldn't get fixed until this bug would be fixed. Uploading 6.1.6 now would give (us/)upstream a couple of more days to figure out a potential *better* way to deal with it. One which should be acceptable for the upstream Stable Kernel maintainers. But I wouldn't let this bug cause further delays to Testing. Testing is meant to test things for the next Stable release and things can and will break from time to time.

I suggest you read the thread (about a dozen posts) starting at https://lists.debian.org/debian-user/2022/12/msg00250.html and particularly messages #252 and #269. These discuss a /possible/ cause of your reported symptoms—you've quoted the topic of the thread at the top of your post. You need to determine whether "getting multiple messages" means that you are seeing multiple displays of the same message, or the display of local duplicates of one or two messages, or actual newly arriving copies of these same messages. Knowing which of these is occurring will help trace the source. I think it's an unlikely coincidence that these messages (particularly if the duplicates are all in the set 252/262/269) would just happen to be the ones causing a random Tbird duplication bug to trigger. The problem could lie further up the chain of processes that deliver the emails. BTW are you running any filters, like procmail etc?

If you click through the links on that page, it looks like Apple is just linking to the source code for open source components used in their operating systems (things like awk, bash, bind, bzip, etc.), but the operating systems themselves are certainly not open source, and cannot be legally used except in accordance with Apple's license terms and / or applicable law. Darwin is the core of modern Apple OSes. It is Open Source and POSIX compatible. https://en.wikipedia.org/wiki/Darwin_(operating_system) But there are plenty of Closed Source parts missing to form either macOS or iOS from it.

Bonjour Bernard, Installation de caméra dans un premier temps, une ou deux. Je souhaiterais pouvoir les consulter partout, même à l'étranger quand je suis en déplacement.

HTTP Proxy
I am installing Debian 11 from a single CD. My plan was to complete the install via the internet. I am using my home router IP address 192.168.1.0 device number 45. However I have no idea about what to specify as an HTTP proxy. I have tried a couple of options but when Debian tries to connect it fails. Communications is my weak point, so basic advice would be appreciated. Larry

Bonjour Pascal, Merci pour cette info, tu as un exemple d'utilisation ? La commande de bernard est vraiment bien... par contre si l'un de vous connais exim (je suis plus à l'aise avec Postfix), je cherche le moyen d'ajouter notre relais smtp pour l'envoi automatique d'un mail du rapport à la fin de la commande.

[ HS ] find et les gros fichiers
Bonjour, Je suis en train d'essayer de chercher sur un partage samba d'environ plus de 1500 utilisateurs (solution libre eole / scribe) ceux qui auraient des gros fichiers. Les répertoires a, b, c, d, . z héberge les comptes utilisateurs. Pour ça j'utilise la commande find find ./a -xdev -type f -size +500M Ca fonctionne plutot bien, mais je dois à chaque fois changer la lettre, est-ce qu'il est possible que la commande pour le dossier "a" passe en suite au répertoire "'b" autrement que de faire un script en l'éxécutant l'une après l'autre ? J'aimerai aussi afficher la taille des fichiers, mais je ne vois pas comment combiner la commande "du -sh" pour qu'elle m'affiche la taille en bout de ligne. l'idée est de constituer un fichier à transmettre à ma hiérarchie. Je suis preneur de toute idée ;-) -- david martin

Resize2fs Questions
I figured I would start a new topic as none of this pertains to the previous messages I posted. I've got an almost 30-GB disk image of a working debian installation for a Raspberry pi that I should be able to easily squeeze on to a roughly 8 GB SSD card because it only takes up 10% of the 30-GB card and I think I am close but not there yet. Because I hate drudgery with regards to syntax, I wrote a little shell script that makes it easier to duplicate the same actions and also makes it easy to show exactly what is happening so far. The big image name is rpi1_good.img and it is 29 gb in size. Here are the commands that work so far. #!/bin/sh #This resets everything for a new run. sudo losetup -d /dev/loop0 #copy a backup to the image name to start fresh. sudo cp -p rpi1_good.img.bak rpi1_good.img #This takes about half an hour. Now, get to business. sudo losetup -P /dev/loop0 rpi1_good.img #This should show 2 partitions on loop0 when successful. sudo ls -l /dev/loop0* #You get /dev/loop0p1 and p2 #e2fs is required to run before one can resize. sudo e2fsck -f /dev/loop0p2 #I should be telling resize2fs to squeeze everything in to a 7GB #partition. sudo resize2fs /dev/loop0p2 +7G There are no complaints up to this point and resize appeared to work so now it is time to reduce the size of partition 2. This may be where things go off the track. I run sudo fdisk /dev/loop0 and fdisk tells me it is 29.9 GB which I expected since Partition #2 should be mostly empty but for the OS and my login directory. I note that the starting sector for P2 is 137215 since one must start at that sector and then I delete P2 and then add a new partition which defaults to 2. fdisk prompts for the first sector with a default of 2048 but I type in 137215. The last sector is in the 62-million range and I want only 7 GB as the size so I type +7G and it takes that. I then type w to save the changes and there is no complaint. The first hint of trouble is when you do fdisk -l /dev/loop0. The size count is still almost 30 GB but then a ray of Sun in that P2 has a size of around 7 GB. I outwitted Murphy this time by using another file on my computer as the target rather than the SSD card so that if it went over 8 GB, nothing annoying would happen. I watched on another console as the size climbed past 5 GB, then 6 and 7 GB and then it was up past ten so it was going to do the whole 30 GB if I hadn't stopped it. I am not sure what I missed but the manual page for resize2fs warns you to use something like fdisk to trim off the excess empty space which is what I thought I did. I would also have thought that the disk image file should have deflated like a punctured air mattress but it didn't. I think I am almost there but obviously not yet. Thanks in advance for ideas. Martin
Re: SD Memory Card (was The Raspberry Pi that Took a Day Off.)
There's always one more question that nobody mentions and none of the articles one finds on the topic don't touch. When looking at the man page for resize2fs in debian, it talks about the -b option to turn on "the 64 bit feature." __ When shrinking the size of the partition, make sure you do not make it smaller than the new size of the ext2 filesystem! The -b and -s options enable and disable the 64bit feature, respect- tively. The resize2fs program will, of course, take care of resizing the block group descriptors and moving other data blocks out of the way, as needed. It is not possible to resize the filesystem concurrent with changing the 64bit status. __ Do I need this since the Pi runs an ARM processor which would make the command #sudo resize2fs -b /dev/loop0p2 6.3g or is it the same command without the -b flag? I have determined that the 28.9 gb SSD card is 10% full with the debian installation and the files I want in my login directory. I found a 7.3 gb SSD card that has probably never been used that came with the first Raspberry Pi I bought around 2012 or so, going for a 32-gb card instead. If I shrink the Linux partition to 6.3 gb which is what the small card had available, I should have it about 40 or 50% full. I can then safely dd it on to a larger card any time I want to do so and then use resize2fs to expand the Linux partition after it is installed. What I did so far was to mount the 27-gb partition on /mnt through /dev/loop0 and edit /mnt/etc/hostname to reflect the host name for the system being rebuilt. The edit changes the image which is really neat. All that is left is to shrink it down to 6.3 gb and it should be ready to dd on to the 7.3 gb card which should be bootable on it's own but which I will use to seed a new 28-gb system that can be customized after it is running. Many of the raspbian distributions have a #1 partition that is a small fat32 lba partition for Windows users to be able to activate debian from Windows. Is this even necessary once one is using unix tools on the disk? Thanks to all the good advice from everyone. I am seeing the end of this project and have learned some new useful tricks that are good to know. Martin
Re: SD Memory Card (was The Raspberry Pi that Took a Day Off.)
My thanks to everybody who has responded here. I think the prudent thing to do is use a new SSD card and I have one that is supposed to be a full 32 gb. The card I was able to finally clear the partitions on is several years old but I think it is still good but the suggestion to use it in a less mission critical application is a good idea plus it is not a full 32 gb. I have a radio receiver that can store information on one of these cards and I'll use it for that since if there turns out to be a bad cell somewhere, the world won't end like it can if one's kernel or sector information becomes corrupted if it happens to land in a vital piece of code. Again, many thanks. Martin McCormick

I suspect this is the crux of the problem. the adapter I connected is a card reader. You put the SSD in a little plastic jacket that holds the SSD in such a way that the card reader can access the edge connector but the holder jacket has no electronics. There is a small notch in the plastic of the jacket on the left edge and the right front corner of the plastic carrier has a diagonal cut to prevent someone from putting it in upsidedown. Since I posted, there is good news but I still wonder if I am not going bonkers because after unplugging the Sony card reader and plugging it back in, I now am getting device /dev/sdg instead of /dev/sdh. I was also able to do the following: #sudo fdisk /dev/sdg which gave me the fdisk utility as before so I did what crazy people do which is to do the same thing as before, hoping for different results. By Joe, I got them. I typed d to delete a partition and it put partition 2 up as the default candidate as before so I selected it and then typed d again which told me that only partition 1 was left so it was deleted. I had gotten this far before so wasn't too excited but type w and this time got the message stating that the partition table had been rewritten and fdisk then exited. Now, doing sudo fdisk -l /dev/sdg yields 1wb5agz martin tmp $ sudo fdisk -l /dev/sdg Disk /dev/sdg: 28.8 GiB, 30908350464 bytes, 60367872 sectors Disk model: USB HS-SD Card Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x680226ff The partitions are gone. My latest screwball theory is that the Sony card reader went in to some sort of protective mode after the dd operation overwrote the device. My unplugging the reader and plugging it back in reran the driver which reset the protective mode back to normal which may be why it all worked right this time. One last question: Since the image will still be too large as it is, can tunefs be run on it or a copy of it to shrink about 4 gb of user space? The good system I copied the image from only had about 12% of the partition used so I should be able to transplant it to the smaller disk if tunefs can do that and still leave a bootable device. Thanks for all useful ideas. Martin McCormick

Great suggestions but I can't. Part of the typescript output I included was me doing just that and I was root when I did it but the squawk is that I don't have permission as if I wasn't root. If writing to the SSD card was possible, I could have just done the dd command, only with a smaller input image and it would have worked. Thank you because what you suggest would be the normal way out. Martin Martin

Charles Curley writes: > I'm no expert on RPis, but that sounds to me like the SD card is > protected against writes. Check for any physical write protection > switches on the card itself and the holder. Thanks for the suggestion, but this is one of those SSD cards that often is found in a camera and resembles a wafer the size of a thumbnail. It has a projection that acts as a key way to keep a user from inserting it in the wrong way and there is a groove for a fingernail to help pull the chip out of the socket. This particular one was reading and writing just fine until I bricked it by the DD that must have overwritten some address which now makes it unwritable. It went from good to bad without my removing it from the card reader so there should be some way to at least clear it for writing again. Apparently, it stops being writable if the partition table is corrupted. In my case, I just want to delete both partitions and start over. The OS is debian Buster and has all the tools you can expect to find and runs on a 64-bit ARM. Otherwise, it's pure debian Linux. Martin
SSD Memory Card (was The Raspberry Pi that Took a Day Off.)
I thanked the person who responded to my post and reported that there were no unusual log entries in syslog on the failing system so not much to go on. I decided to upgrade the Raspberry Pi which was suddenly having this mysterious problem as I have backups of the failing system so I figured I'd just clone a buster image from another Raspberry Pi that is running buster and use dd to copy it to the Raspberry Pi which was running stretch and having that weird problem. Then, assuming the upgraded Pi was alive, I could use the backup from the stretch system to put all the user space from my old home directory on the new buster system but I messed up again. The SSD card from the older system is 28 GB and the working buster system's SSD card is 32 GB so the smaller card filled up and I achieved that "no space left on device" state that we all love to see. Simple, I thought. I'll just delete all partitions, and do the dd if=rpi_good.img of=/dev/sdh which is where this card shows up when it is in the reader and I can maybe dd a smaller 8.5-gb drive which I have that has almost never been used. Murphy has struck again. Here is what happens when I try to use that 28-gb SSD card: Script dump follows Script started on 2022-01-26 20:03:52-06:00 [TERM="Linux" TTY="/dev/pts/3" COLUMNS="80" LINES="25"] 1wb5agz martin tmp $ sudo su - [sudo] password for martin: root@wb5agz:~# fdisk -l /dev/sdh /dev/sdh: 28.8 GiB, 30908350464 bytes, 60367872 sectors Disk model: USB HS-SD Card Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x680226ff Device[0m [1mBoot[0m [1m Start[0m [1m End[0m [1m Sectors[0m [1m Size[0m [1mId[0m [1mType[0m /dev/sdh1 8192 137215 129024 63M c W95 FAT32 (LBA) /dev/sdh2 137216 62333951 62196736 29.7G 83 Linux root@wb5agz:~# fdisk /dev/sdh Welcome to fdisk (util-linux 2.33.1).

The SSD passed a fsck test earlier in the day before I blew it up so the chip should be salvageable. I don't care for recovering either of the two partitions which will be overwritten anyway if the SSD can be made writable again. One can mount /dev/sdh1 which is the fat32 partition but it mounts as read-only. If you try /dev/sdh2, you get a squawk that says that this partition is not in /etc/fstab which is certainly true but it doesn't mount either so mount doesn't understand what I was trying to do. This is the partition that got the overflow condition so it's utterly useless. These last 2 days, I have been a day late, a Dollar short and 1 step behind on what shouldn't be really that big of a problem. Martin WB5AGZ
The Raspberry Pi that Took a Day Off.
This Pi is running Debian Stretch. I believe that's what version 9 is called. I have it capturing audio from a radio receiver and it's been doing that for several years now and it was doing that yesterday morning. Later in the day, I downloaded more audio and, after a long pause, I got the message from ssh that the Raspberry Pi wasn't there any longer so I retrieved the Pi from the room where it was and brought it to my Debian desktop system to work on it. I could login to the Pi which seemed to be up and running but the short story is that it couldn't talk to any address but our router.I couldn't even ping it's interface from the Pi, itself. If I was on the Raspberry Pi's console, everything looked normal as long as one wasn't using the TCP/IP interface. You could even do a ip addr or an ipconfig -a command and it would show that it had gotten the correct address from our dhcp server which is in the router. It would successfully ping the router but no other addresses, not even the address it uses on our network. I finally quit messing with it and went to bed but fired it up again today, January 25 and low and behold, it just came right up and is now back doing what it has been doing. Is it possible that it got a corrupted lease for dhcp from the router? Dhcp leases on our Netgear router are issued for not quite 24 hours so it may have gotten a bad lease, kept renewing it for the time it was powered up and then it got a new version of that lease today and all is well. It's the same IP address because I have put it in the router as a static IP address. The other thing that is weird is that the Raspberry Pi in question has both a wired Ethernet and a WiFi interface and both were misbehaving identically. Normally, the wired port is not used and the dhcp lease renewal process happens over WiFi. The results of ip addr always showed a correct subnet mask and the only rules in iptables are the 2 default rules. In other words, all looked normal except that it didn't work. While I had it on the work bench, so to speak, I ran fsck -fy on the SSD card since it has been a couple of years since I last did that and there was not a single squawk about anything. Thanks for any ideas about how things got wrong and then magically fixed themselves. When I turned it off last night, I gave it the halt -p command. The power supply has no switch so I unplugged it from power so it started fresh about 8 hours later. Martin WB5AGZ
Re: /usr/share/calendar.usholiday
deloptes writes: > And if you look into the file, you see it has no years associated with the > date, so it doesn't matter when it was written unless there was a change > in > the official holidays in the US. Correct. I see two types of date references, exact dates such as Christmas and New-year's and rule-based dates which are some designated day such as the second Monday in a given month, what the British refer to as a "bank holiday." My original question about this file has been answered in a round-about way in that there are also two types of holidays. St. Valentines day, for example, is not a postal or bank holiday but one will certainly get in deep trouble on the home or romantic front if that day is forgotten. Also days like Arbor Day are a nice idea but nothing about normal commerce or daily activities changes I also noticed that today in the United States should be marked but hasn't been yet. It is the third Monday in January which, since 1986 has been the official recognition of the birthday of a US civil rights leader, Martin Luther King Jr. The entry in that file probably should read: 01/MonThird Martin Luther King Birthday (3rd Monday of January) It is now a major holiday and schools and government offices are usually closed so it should probably be there. Thanks to all and sorry if I created any confusion about the path. Martin McCormick.

/usr/share/calendar.usholiday
There's a stale version of this file on my system that reflects when Debian was installed but it brings a question to mind. Does this file simply cause messages to appear on an event calendar or can it be used along with crontab in some way to either cause or prevent cron jobs from running if a date matches one of the dates in the file? I use cron and at jobs all the time and have thought that it would be nice to skip some jobs if the day is a holiday and the result might be not what one wanted. Right now, I don't think this file is doing a thing as it is for 2017 but this is why I am asking. I also saw versions of that file for other countries such as the UK. Thanks for all good responses.

Curious Question about an Extra MAC Address
I was inventorying all the systems on our WiFi and wired network so I did the following: sudo nmap -sn 192.168.1.0/24 followed by sudo arp -a and I found nothing extraordinary so I also got on our Netgear router and told it to cough up a list of attached devices, showing the same list of stuff that the first two sweeps found. Additionally, there was 1 mac address with no other information such as an IP address or system name, just that MAC on a row all by itself. I had been looking for our DVD player which has the ability to view streamed movies and I think this might be it. As a computer user who is blind, I don't directly use this player but my wife does. We usually play DVD's from it however she did use it once to watch a movie off the network and it worked fine. I asked her if she remembered giving our WiFi password and she said no but was given a message to go to a certain url to authorize payment in order to watch the film and it all worked down to the monetary slurp so this is not a complaint or gripe about anything. My question is, did the link she went to on the computer or maybe her iPhone use javascript to get our WiFi password and if so, how did the player get the authorization to use our WiFi? The stray MAC showing up on the router is probably the player broadcasting an attempt to get in the network but to do so, it has to send the password in order to get a DHCP lease which would then allow it to get on the internet. I am just curious about how did this work and could a person cause it to log on to our WiFi network and receive a video stored on a system here? I'm not trying to rip anybody off but it's good to know what extra features are under the hood. What I am actually thinking of is more like a DVR where a computer can record a TV show like the old-school VCR's and then one could play it back through the DVD player on the network. This player can also update it's firmware when necessary and we've never been prompted from it for a WiFi password. It just seems to be able to get through when it needs to. I guess this could also be a neighbor trying to mooch WiFi, but I doubt it. Everything with an IP address belongs to us and there are no odd amounts of data coarsing through our router that aren't caused by us.

One more question I should know the answer to but am not sure of. The debian Buster system I use for email presently uses fetchmail to get mail from the ISP and is configured to use that ISP's smarthost for out-going mail. I do not want to effect (= muck this up) this functionality because it works well for now. Shouldn't I be able to install an imap server on the debian box and forward messages of interest to it, then reach imap4 on the private net from any system that speaks imap or has an imap client? That would do what I need to do. When I was researching, the article in wikipedia I read said that many commercial systems have email clients which understand imap, pop3, etc. The systems likely to do this on our network are a windows10 box, an iMac and maybe an iPad. The idea would be to forward an email message needing this attention to imap on the linux box, contact the Linux box from one of the devices I mentioned, and download the message at which point it would e as if that system had been hooked up to the ISP and received it. I was all ready to use .local as our domain name and then I looked that up and there is a good wikipedia article which explains how that is problematic and recommends using something like .lan, .office or something else that isn't likely to be registered as a top-level resolvable domain name. The machine I receive email on presently would be a good candidate for running a mdns but our netgear router advertises whatever dns's the isp uses for obvious reasons and that's fine but it would be nice if the mdns's address could also be known to clients on our network which could make DNS queries to each other's names that would resolve properly. Is there a way to advertise the mdns so that the router picks it up but doesn't drop the internet DNS's that we all need to resolve the rest of the world? I do remember when I was working, we explored open-source network authentication systems which involved fake DNS's that one had to advertise as such so their information wouldn't corrupt the proper working DNS's which could really mess things up if somebody happened to pickup and cache the wild card * that sent all new supplicants to the authentication server after they were already up and running. In our case, the corruption would be okay and done for good reasons but the dhcp server in our router already advertises two domain name servers so ours would have to be learned about by discovery. Thanks again. Martin McCormick

As for there being 16 subnets in the 192.168.x.x number space, one can use variable-width subnet masks so unless you have a lot of hosts or, for some reason, are sharing space with another subnet, one can spread out to a Class B-style network which would be the whole space and have a subnet mask of 255.255.0.0 or you can make lots of little subnets of various mask sizes with blocks of 16 addresses being about the smallest subnet that is practical. Remember you always lose the all-zeros and all-ones broadcast addresses because they are special plus there is likely a router address taken by the router which leaves 13 addresses for hosts in each subnet. I remember early in the nineties our campus went from a single Class C to a Class B network and the whole campus used the Class B subnet mask with bridges holding the whole thing together. You should have seen some of the arp storms that would blow up like wild fire when somebody had a misconfigured host trying to be helpful or maybe deliberately misconfigured because somebody got their socks in a wad over something and started the fire on purpose. It wasn't long before we began more efficiently using the number space with big departments getting let's say 1024 or 512 possible addresses and others getting 16 or 32 addresses. By the time I left, we were using the huge private network space of 10.0.0.0 with aNAT or Network Address Translation to parts of the old Class B network and it generally worked well. I wrote a C then a perl program which would assign IP addresses for hosts on our networks that knew the sizes of all the subnet masks so assigning IP addresses was something anybody in our group could do without much more information other than what host name the customer wanted and what building it was in. My job was basically to encode all that in to rules for automation to keep us safe from making mistakes and it worked. Martin
eMail Com Between Hosts on a Private Net
The installation, here, is like millions of others. We are on a private VLAN with the router acting as the gateway to our ISP's network and the internet. There is nothing unusual about that so the question is Can systems on a 192.168.x VLAN use smtp to send mail to each other? I really should know the answer to this because I am a retired systems engineer who used unix systems and mailers all the time but that was in a university network and I would just assign a DNS name to each box and maybe a MX record if it was necessary so that box1.midlevel.edu could deliver mail to box2.midlevel.edu whether it was across the room or on another continent. The DNS support is what you don't have on a private VLAN so I want to do this in a safe but simple way. This would make it possible for Linux boxes on the network to send messages to the system I normally receive mail on so that squawks about a process crashing or some other problem are sure to be seen. The other systems sending those messages don't even necessarily need to send mail outside the network but they do need to send mail to the system I normally read mail on. I looked up this topic using duckduckgo and found very little hits that were on topic and lots of mercantile buzz about email hosting companies, etc. All are necessary but not what I was asking about. I have put static IP records in to the dhcp server on our router so 192.168.1.xx will always either have a specific host at that address or nothing if the MAC address changes and the record hasn't been updated. Also, I have put /etc/hosts files on Linux systems and a Mac and I believe there is a hosts file one can add to Windows systems for a similar effect. Thanks for any good ideas. Martin McCormick

Re: Proprietary USB Drivers; Ya Gotta' Love'em.
So, what is the easiest route to end up with a kernel that has this patch in it? The image for the current kernel is 4.19.0-5-686-pae The Raspberry Pi is an arm-based system and the image version number is probably different but the idea is the same, have a kernel that doesn't choke when one is using the ICR-30 usbC port. To put it bluntly, this is an area of Linux I have very little familiarity with because generally, Linux kernels just work so this is a left-handed complement in that I think this is the first kernel bug that I have encountered ever. I am sure I have run kernels with other bugs that I didn't know about but this is the first time one has bitten me, so to speak. Thanks. Martin WB5AGZ Martin McCormick WB5AGZ

I did forget that but you are correct. another interesting thing about ssb which includes both sidebands is that it was first tried during the 1930's as a concept and had to wait until after World War II before amateur radio operators, the millitary and commercial folks began using it routinely. To not stray too far from the group purpose, the usb dongles that give you a wide coverage receiver from 26 to almost 1000 MHZ use basically math to decode sideband, AM, FM and data using DSP techniques.

That's got to be it. I've been doing debian Linux since right around 2000 but I must admit that I don't know the easiest way to include the patch referenced in the second link. I will need to do that on an i86 box plus the Raspberry Pi I first discovered the issue on since I am apt to have the radio connected to either system and, if this problem is fixable, this solution is preferable because the radio defaults to using the usbC port as the serial port so it should still work if a full reset is ever needed and the mechanism for usb should naturally accept as many different devices as practical because you never know what you will need to connect until you try it and it fails. As an amusing aside, the radio has a usb mode, but that's totally unrelated because in that case, USB stands for upper side band and is a very energy-efficient method of radio communication because it is only a spectrum of frequencies consisting of the sidebands of an audio signal without the carrier. It can be LSB or lower side band or USB for upper side band. Nothing like a few new acronyms for your day. I guess that's TMI. Martin McCormick WB5AGZ
Proprietary USB Drivers; Ya Gotta' Love'em.
This is an embedded usb serial port in a radio receiver which works in MS Windows10 and I was hoping to write some control routines for a Raspberry Pi running buster and it does the following: Sep 22 20:17:15 rpi2 kernel: [551843.541477] usb 1-1.2: new full-speed USB device number 6 using dwc_otg Sep 22 20:17:16 rpi2 kernel: [551843.674681] usb 1-1.2: not running at top speed; connect to a high speed hub Sep 22 20:17:16 rpi2 kernel: [551843.684432] usb 1-1.2: New USB device found, idVendor=0c26, idProduct=002b Sep 22 20:17:16 rpi2 kernel: [551843.68] usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 Sep 22 20:17:16 rpi2 kernel: [551843.684452] usb 1-1.2: Product: IC-R30 Sep 22 20:17:16 rpi2 kernel: [551843.684460] usb 1-1.2: Manufacturer: Icom Inc.

There is one other possibility. It is possible that one can go to one of the menu options and flip a virtual switch that will take the serial data that should have been on /dev/ttyACMx and put them on a logic-level serial line that is accessible through the right stereo channel of a 3-conductor jack. Whether or not that works is beyond the scope of this list so my question is whether or not there is a wrapper program of some kind in Linux that can fool an application like the serial port module that tried to run here in to thinking that it is home and among friends when it's really been kidnapped. The possible use of a logic-level serial line is probably what I will need to do but that means that if one resets the radio to factory defaults, one will have to go in to the menus on the radio's screen and restore the virtual switch setting. As a computer user who happens to be blind, that's a major pain as well as in a case where the radio is remotely located and one is operating it headlessly. I smiled a bit when reading the syslog admonition to connect to a high-speed hub. That would be quite a trick. Thanks for any constructive suggestions. Martin McCormick WB5AGZ
