Sorry but a command line only solution is needed.
Phone/buffer/limit/lockup smells of dodgy software. That whole
MTP/PTP/bla bla is a load of junk the way I see it. A Microsoft
solution.

[Linux-users] Ubuntu auto-mounting smartphones
Since this list was meant to be for tapping into combined knowledge, here's a problem I haven't found anything about with some searching. A box running Ubuntu 22 has a weird way of handling smartphones and mounting them as multimedia device (they're not USB storage any more). Graphically things work but that's not a suitable way to go about things as it prevents the use of rsync. How can I prevent the GUI desktop from touching the smartphone with some kind of automagic mechanism? Mounting the phone with mtpfs works but only with great difficulties and requires a ninimum of 2 atttempts. Something in the system opens the device and blocks it, the desktop shows it as mounted but the mount command shows nothing (i.e. it's not a block device or FUSE file system). The trick is to unmount the phone on the desktop, mount it as mtpfs, and do this at least twice in the race against the desktop while answering Android 13 questions about whether letting the phone be mounted is acceptable to the phone's owner. Arrg. So question, how to make the desktop automagic shut up? Does someone with Ubuntu internal knowledge have an idea?

Re: [Linux-users] Router and broadband advice? (offtopic)
I don't think it's really offtopic. If you have a good firewall already you shouldn't need the router/firewall functionality of the Cisco thing the provider is suggesting. Their suggestion is probably based on the assumption that the customer has nothing already and is ignorant. Unless the connection comes in from the street as Ethernet you'll need some kind of modem that connects to the fibre on the street and gives you an RJ45 to plug into. Perhaps their suggested expensive Cisco model has the modem already built in. If you get your own suitable modem you might have to fight the provider for the setup details. How long would it take to switch from the cheap to the expensive plan? You could start on the cheap one and test it out, if it's too congested switch up. Or get both plans and connections for a month or two so you have an immediate fallback. Given the relative costs the cheaper plan looks almost irrelevant. > The much higher speeds and lower price are > definitely enticing but we couldn't operate if speeds fell below 30 to > 50 Mbps.

Before you ever do anything else, you boot a rescue disk, yes that runs from RAM only, and use smartctl to inspect the disks for failures. Any failed disks you get your data off first as much as possible, then you replace it. Should the rescue CD/USB stick not boot fix your hardware first. Culprits are cabling and bad connections at the connectors, if you're lucky (re-plug all of them 5 times), disk PCB failure, mobo failure (not only in the disk circuitry, could also be RAM and CPU). Ehm, maybe re-do the connections before booting a live disk. Do not attempt to write to any disk until you have verified that they are functioning, or you reduce your chances of getting your stuff off considerably and you're wasting your time re-installing anything on them anyway. But that should have been obvious to anyone. > Boot-Repair-Disk. None of the install disks appear to be writing to > the mbr. Some mobos, especially newer ones, have a BIOS setting (ugggh or UEFI) to disable MBR writing. You'll need to change that setting first. grub 2 is a bit more painful regarding config files and config directives. Fixing that up from a rescue disk can be a challenge, especially if you have a pile of different OSes installed and some braindead distros don't leave the commands used to install grub in a file somewhere. It's easy to make mistakes here and have the system not boot as you like. But check your hardware first.

That's the perfect reason why you need a gazillion email addresses. Or at least one for each half dozen max online shops, and anpther one for each bigger thing. Basically, you want to be in a position to change/delete any address at any time without loosing anything you care about. I'm routinely getting spammed suddenly twice a week after years of silence because I ordered a PC part there once. When I tell them to stop it (no need to be friendly) the sh*ts tell me about their new website 2 years later... and take that as an opportunity to start it up again... Secret email address for online banking is the number 1 phishing protection (unless you're clueless on Microsoft or Android and get your address book swiped all the time). You have one gmail for absolutely everything? Why not let google track you every single email of the way and allow everone else to link you into everything you do...? Thunderbird has native (no plugin) filter tools that allow you to match emails and take certain actions. I advise you to never delete, but move into a separate folder. You will get your filters wrong... And some actions plain don't work, like forward with attachments included if you set download-attachment-on-demand. Been buggy for 7 years. The downside of getting too carried away with TB filtering is that you then become dependent on TB. You can still only access your email from one client place. That's why I prefer to do my filtering with procmail, which is far more elaborate and capable than any mail client, and then I can choose which MUA I want to use and not create a dependency. All MUAs suck so flexibility trumps. procmail has been stable for 20+ years, or try maildrop. Do save a copy of all incoming email into a folder named year-month, even when you think you have your filters right, you'd be surprised what use you find for it, but you can't do that with TB. Other methods include phoning AA 0800, explaining why you've had enough, threatening a few complaints to xyz and making it crystal clear that you do not ever wish to get spammed again. Or collect evidence and make a formal complaint to the watchdog if you can be bothered. In my experience only talking to them fixes it. I used to tell them yearly I don't want their newsshit, they got it, and with every membership renewal it was back to newsshit. That's a deliberate system design!! With NZ businesses I adopted a policy of emailing them friendly once, and afterwards letting rip in a rude way with whatever means available - I've damn well had enough. They do tend to get the point after that. If I give them a bad day then they should have put the legally required procedures into place earlier. No sympathies. Surely the Greens have a no-spam party policy? Faceplanting that they don't follow it themselves might get some interesting entertainment...

Rooting a device means to exploit one of its fatal software flaws to perform a privilege escalation. That's very version dependent. Your only chance is to search the 'net for an exploit kit (yes, people run those on their computing equipment *deliberately*...). Some exploits may exist that use the android debugger. Then you can use Linux - but it's no particular necessity or advantage. You're trying to break the android system, not the Linux system. Some cheap Chinese phones have been known to ship with an image where they forgot to turn off development before compiling. In the adb shell, type root, then reboot, and on re-connect you have a root shell for adb.

I expected that that would be so, but the foundations determine security
of and control over the whole system, and I am not going to hand that to
Microsoft, whos entire business model is built on controlling my
computer for me, maximising vendor lock-in, and minimising
interoperability. Notice how they managed to control how/if you can
install Linux on a modern computer (UEFI)? I'm also not interested in
having my activities monitored by Microsoft or personal details
transferred each time I turn my computer on ('doze 10), be forced to
upgrade when it suits Billy, or deal with license checks when the only
thing I'm interested in is run Linux. Why add a whole operating system
that I have no use for just to run a VM so I can run the OS I actually
want?
All the scenarios you describe are work scenarios, and all the Microsoft
and security/privacy problems are the business', not mine, so a VM is an
option to deal with computing environment limitations. I don't have
those for personal computing where I define the specs myself.

Easy. A number of places sell the Dynamix patch leads covering the rainbow. Cut off the plugs, crimp on new ones[1]. This is the cheapest option. Buy longer lengths to save.

I have now run rsync in test mode between the major > directories and it returned no errors so I guess... all is well. I don't believe rsync -n does the integrity test you are after. rsync -c would. In any case, there are additional problems with using rsync on a braindead FS like dosfs (or vfat): 1) Time stamp granularity is only 2s, not 1s, or nanoseconds like Linux filesystems had for a long time. Originally the rsync protocol could not transfer the sub-second part of time stamps, so they were zeroed out on the copy (even if both source and destination were local). To decide whether a file needs copying rsync by default only looks at name, size, permissions and time stamp - if they're all equal the file is untouched! Only the seconds of the time stamp were compared - a difference in the sub-second part is invisible to rsync. With this dosfs rubbish you get the interesting effect of every second file (statisticaly) being copied on every rsync run, because dosfs stamps are rounded/truncated to the nearest 2s! Hint: that's what --modify-window=2 is for. 2) This historic Billyshite(TM) is completely unable to handle daylight saving!!! And write in capitals on a note to your monitor "THERE IS NO SOLUTION". It's broken by design. Just wait until daylight saving finishes on 3 April, and start swearing your living daylights, because the times for half of the year are out by 1h. You guessed it: on 25 Sep it's the other half. If you're lucky, running the dumb FS on UTC fixes some of the problems, but not if you have a system running on UTC (e.g. your digital camera). This depends on mount options, and they can only be overridden in one direction. You may play with http://volker.top.geek.nz/soft/odd/ This makes using rsync on dosfs a dangerous proposition, especially with -u, which you'd normally always use. 3) Count the weeks until that useless FS is corrupted. The bigger the disk, the bigger the mess. It is unsuitable as backup. You could try and use it for file transfer only - if you don't mind having part of your metadata screwed up. 4) You already know that it doesn't store/copy your Linux permissions etc. See suitability as backup above. (Suitability for anything yadda yadda android crapola yadda) Your method of using rsync for checking integrity is inefficient too, and it only gives you an answer at one point in time. The much better thing to do is to store checksums in your directories somewhere near the top level. Not only can you verify a copy operation faster than rsync -c, you can also do this any time again later, even if the master copy has been updated. I made a script for that decades ago and would never consider creating backups without checksums. Create checksum for all files in current dir, recursively: md5 -i . Check: md5 -C .

Drives with a size above 2.xTB must have a GPT partition table for the simple reason of the traditional partition table format with LBA addressing not being able to address more than 2^32 512-byte sectors. The surprise is that XP, despite being ancient, recognises GPT sufficiently to say that it can't handle it. There are ways of merging traditional format (up to the first 2TiB) and GPT, but everything says don't do it because it's more trouble than it's worth. So, above a certain disk size GPT is it, nothing to do with M$, all to do with a 1980s format (OK OK, so M$ afterall...). As to filesystem to use, my conclusion is that the best way to operate is to use ext4. If M$ is too dumb to handle it, change system, not filesystem. If you can't: You've been screwed by Microsoft.

Let's forget about photorec, that's just the example for piecing bits together again when your recovered data ins incomplete. The details of the forensic discussion would tell whether the author knows what they're talking about. Heaps of reference has been made to Gutmann's paper and people wrote heaps of software, while forgetting that it all no longer applies to their drives... If you read data can be recovered after dd establish what kind of drive it applies to, if it doesn't say or it's a 90s drive put it on the joke pile. Micro stepping the head in a modern drive is about the only way for Joe Smallfry to get anything at all. Let's assume the firmware is capable of that, and that it has functions for that, because it's how the drive itself finds the middle of the track. Once upon a time drives had elaborate mechanisms to deal with thermal expansion etc, these days you don't care, you just micro-step until you can read something and then you stay with that calibration until your read error rate goes North. These commands are not user visible, but assume they're user accessible as long as you discover the secret command byte for them. Assume this is possible easily (record commands from the manufacturer's disk test utility etc). Btw all IDE/ATA drives are controlled by SCSI commands and always have been, just the connector is different from SCSI, the rest's the same. Back in Gutmann's days write heads were 3 times (or whatever) as wide as read heads, these days in a cut-throat market noone wastes 2/3 their capacity. How much wider do you reckon the write head is now when you can micro-step to the middle? Don't expect spare space between the tracks or any other some such capacity waste. When the drive operates normally, the read error rate is distinctly non-zero. It just hides it from the user with error correction. When you dd zeroes over the track, well-positioned because you can't afford to damage the adjacent tracks, destroying say 90+% of the magnetic recording, your error correction will quickly become non-functional. I believe I've read a paper/etc about that sometime, but I won't find it. Chances of success were minimal and very deep pockets were needed. So when I hear can recover data after dd I want to know how exactly, and with discussion of all the points above, otherwise it goes on the jokers pile (and don't waste any more time on photorec etc please, we're only interested in getting data back, not what to do with it afterwards). The totally safe way to destroy data is to de-magnetise the platter. It's probably easiest for lay people to heat it above the temperature to which the material stays magnetised. Otherwise, totally encrypt the disk over its entire lifetime. Or, my conclusion, you can't practically improve on dd without disk destruction. I'm happy to hear corrections...

You are asking about incoming emails on different servers, and outgoing emails via different servers. It seems pretty obvious that you'd have to direct a copy of each incoming email from each server to a single server, on which you run an SMTP receiver (there are other ways to copy the emails) and an IMAP server. To this you connect with your clients. Sending emails via different accounts is generally an MUA issue, of course it is annoying to have to configure each of them. If your MUA connects to a single MTA then it might be possible to configure that MTA to route according to your mailboxes in use, but I tried a few weeks ago to knock something trivial of that into postfix and didn't get it to do it as needed, so will stay with sendmail. You might find it easier to move all your mailboxes to a single server. Easier organisation, single point of failure. You might find procmail and rsync very useful too.

Search the Internet for shugart bus, that was the company that invented the bus and it was often referred to as that. I am sure I have old drive manuals lieing around, but I don't remember any super special floppy drives having existed. The Olde Apple ][ had an anomaly in the drives. Its magnetic stream recording format was hand-doctored and used a much larger gap between flux direction changes. Normal, standard floppy drives couldn't handle that because their read amplifier lower frequency limit was too high. The trick was to solder 150pF onto 2 test pins, which, somehow, never failed to exist somewhere on the circuit board. They were easy to find too, touching 150pF to arbitrary pins was always non-destructive. It changed the read amplifier bandwidth. Post that Apple I believe all floppy drives were standard, off-the-shelf industry stuff.

Conclusion - NFS doesn't like exporting a tree of mounts. IIRC that has been a design feature of NFS since day one (intentionally or as a side effect I don't know). Isn't there a mount etc option somewhere to change that? But my TV drive is reporting imminent fail, so I'm going to deal to that. Comments? Copying off asap is a wise move. But using NFS for that?!?? USB-SATA bridges and SATA chipsets may all have a max size for the disk you can connect to them, probably especially the USB stuff. For this kind of exercise (copying 3TB around) USB doesn't cut the mustard (too slow, too much trouble) and a direct SATA connection is desirable. Don't you have any computer with a spare SATA slot that can handle 3TB? You don't even have to power that computer down, just connect SATA data cable and power the disk somehow. If the SATA chipset is properly supported under Linux a hotplug event will make the disk available soon after. I've done it several times. (No, do not hotplug other stuff on the mobo, like plug-in cards...) rsync is the way to go for copying (though it may truncate time stamps to full seconds), but more like over TCP or ssh, not NFS?!??

Please run memtest86+ for at least one full iteration, several if you can. There is a program called memtester which you can run while the box is running. It allocates physical memory (as root) and lets loose on that chunk. If it finds a problem you know there is a fault in the memory system (may not be the memory module!), but not at which physical location. If your box goes stone dead when starting memtester you know you have a problem, and it's not the hard disk. Beyond that you're pretty much into replacing components until it becomes stable again. Recently it took me ages to find the problem causing exact same symptoms.

I was thinking of it coming under the heading swap components until it works again, but it doesn't hurt to mention it explicitly. It is possibly easier to try a different supply from another computer instead of swapping cards. Another one I heard recently is that SATA DVD drives, when faulty, can interfere with and stall the boot process. Pull off SATA cable, try again. Btw I found memtest86+ to be only so-so. If it flags an error there is a problem, but if it doesn't it means absolutely nothing. Basically, good luck. If the lockups are only every month, or every week, it's impossible to find the problem. Any fault that can't be triggered can't be fixed (other than by total replacement).

No I haven't used them and their server is down. Depends on what you want to do with them. If you want to monitor some workplace computers they're probably ok. For home I wouldn't touch anything that is wireless, and you have to decide how often you can be bothered to swap batteries. Check specs, if it doesn't tell you humidity accuracy properly it's a guesstimator only (which might still beat your motherboard?!??). Consider hacking up an arduino solution. For temperature that is totally trivial, using DS18B20 sesnors in TO92 case. For humidity much code exists for various sensors too, however most of thm are neither terribly accurate nor calibrated. If you don't care that's easy, if you do it's expensive. Excellent sensors are the SHT21 and similar from Sensirion, easy to use, but you pay for quality.

Not necessarily the wireless box either. First you need to establish without doubt whether this has anything to do with anything(!) wireless. Hence you give everyone a cable for a week and turn the wifi off. I've seen these symptoms on an xtra broadband connection when the useless xtra name server where configured. Every so often for days in a row, every Nth page load in the browser wouldn't connect. Check what name servers you have configured. There are still a few public recursive name servers left you could use for a week or two, but they are getting rare. (I wouldn't use google or spammers like opendns.com.) But you say Telstra cable modem? They don't work unless your public IP is loaded into the network interface of something else in your house. If you use your wifi box for that you can't turn that off and you can't see which side the problem is on. You're going to have to replace the wifi box with something else temporarily.

The software in question required gtk3, ao I assume it's a desktop application. How does installing a gtk3 library(!) on your desktop, for the exclusive use of one desktop application, affect your mysql, php, nginx, etc.? So far, your no-gtk3-on-my-desktop rule seems arbitrary and nonsensical, so I'm interesting in your resoning (which so far I fail to follow). IMO bleeding edge has no place in the production environment. That may be so, but your desktop is not a production environment. If you need a proper staging server, install one. Virtualbox is good.

Re: [Linux-users] Time recording software...
One thing that a career in the IT industry has taught me is that if someone requires the latest and greatest version of something ( or if the documentation is complete crap ), then treat it as alpha software at best until proved otherwise. Agreed. We differ on whether installing gtk3 interferes with your desktop. I assume it doesn't until tested and found otherwise.
