From what I recall, the personal storage size limit is usually set by the system. You might need to dig into some advanced settings or maybe even try a different tool to resize it beyond the 4 GB limit.

The limit is set by the filesystem type. fat32 has a 4g limit.

We have to re-iterate this from time to time, so here we go. BIOS/Init processes automatically generate SD? assignments. There is absolutely NO guarantee that the disk that was '/dev/sda' this time will be 'sda1' next time. So how to solve? Use the UUID's people. That is their sole reason to exist. ...

I universally us 'rsync' for these tasks. It only updates changed/new files. Mind the positioning of the forward-slash.
sync-dirs.sh:

Code: Select all

#! /bin/bash

From="/path/to/source/directory"
To="/path/to/destination/directory"

# Sync directories:     
rsync -avu --delete $From $To/
sync

The following console command will display all detected WAP's, bypassing the various connection apps. This will show the raw output of what WIFI linux can see. Change the 'wlan0' to match your specific wifi adapter. iwlist wlan0 scanning | egrep 'Cell |Quality|ESSID' This is useful to isolate hardwa...

Jafadmin

Always remember that ALL wifi is RADIO. Different 'dongles' have different antennae schemes. There are a thousand things that can affect radio. Even where you sit or move around in a room. Density of nearby WAPs and transmission stations can also affect you. Worth noting; When you use a fixed wifi p...

It should show up as '/dev/ttyUSB0' or something similar. You can set it up using the 'stty' command if needed:

Code: Select all

stty -F /dev/ttyUSB0 9600 cs8 -cstopb -parenb

Here is a CL script I use for WPA. Notice it uses different wpa_supplicant drivers depending on adapter. I arrived at this via trial and error. YMMV. You can choose whether to use dhcp, or manually config the address. #!/bin/sh # A script to start WPA/WPA2 wireless # XRUNNING=$(ps | grep [X]org) FAS...

In the past I have solved this problem by plugging in an additional keyboard. The OS will not transfer the second one to the VM. Ctrl+Alt+F1, then kill the offending process.

dd doesn't care about permissions. If you tell it to overwrite a disk, it will. Even if it is mounted.

If dd won't work on it, it has a hardware problem. Probably going bad. This is common.

good luck.

Jafadmin

Phil, it would help to know which Wifi tool you use to connect. I'm assuming it is using wpa_supplicant. You are probably going to need to make sure your *.WPA2.conf file is latching the MAC address of the repeater instead of the router. Another thing that may help is to make sure your connection to...

Jafadmin

On some you can just press and release the power button which wakes it up. I think it is BIOS dependent.

Jafadmin

How would that differ from a version-compare utility? The pup-tools pet in EasyOS has 'vercmp': # vercmp --help usage: vercmp version1 lt|gt|le|ge|eq version2 return value 0 if true, else 1 64-bit pet: http://distro.ibiblio.org/easyos/amd64/packages/pet/pet_packages-pyro/pup-tools-20190828-pyro64.p...

The other problem is that ' if [ $NumVar > 0 ]; then blah blah ..; fi' will often have the hidden side effect of creating all those wierd little files you see from time to time named '1' or '0' with nothing in them. That's because your syntax is wrong. ... Yep. Ever had that happen? Yep. That's the...

Jafadmin

Your program always returns 0 (unless an error occurs), meanwhile test returns 0 if the condition is true, 1 - if false, and 2 on error. With decx doing the same, it would be possible to write simply decx $num1 LT $num2 && echo yes || echo no insread of [ $(decx $num1 LT $num2) = 0 ] &&...

Jafadmin

((2>1)) && echo yes || echo no doesn't create files. But if it's for bash, why putchar and not an exit code? It does do exit codes. So we need to do both. exit code AND a result. decx does comparisons AND math operations. echo `decx 34.025 T .003 -p=4` ('T' means x) 0.1021 It's purpose is t...

Jafadmin

It does floating point math and negative values

decx -89.1 T 32
-2851.2

decx -89.1 LT 32
0

decx 37.69911 D 12 -p=8 #

Firstly, 'bc' is cool. But sometimes it can take most of a cold beer to figure out how to get it to understand what I'm trying to do. The other problem is that ' if [ $NumVar > 0 ]; then blah blah ..; fi' will often have the hidden side effect of creating all those wierd little files you see from ti...

Jafadmin

Whole whopping big bunch of variables in this topic. USB port speed, USB thumb speed, filesystem type (Fat32, for instance can format in seconds), processor speed, and how much RAM you have, to name a few.

So, the short answer is: YMMV

Yeah, I know ..

@Jafadmin On the topic of the location of the pupsave file, you gave some sample code: psave=778e3ad4-b9d8-11ed-afa1-0242ac120002:PupsaveDir/pupsavefile.4fs You refer to UUID of SDA1 partition. Can you tell me, please, where can I find this ident. (778e3a.... etc) code? I presume I might use anothe...

Jafadmin

Typically you do this in the menu.lst or grub.cfg file on your USB. Add a "psave" parameter to the "kernel" or "linux" line that looks like this: psave=778e3ad4-b9d8-11ed-afa1-0242ac120002:PupsaveDir/pupsavefile.4fs Where the UUID is the UUID of your sda1 partition, &qu...

Cliff Notes version of what mikeslr said: If using LotsaLuks: 1) create a LUKS file the size you want formatted ext4 with default encryption settings, in the same place as the other puppy boot files, and mount it. (name the file something simple for now) 2) copy everything from the 'fossapup64save' ...

You will find all you USB controller information at:

Code: Select all

#ls /sys/bus/usb/devices/usb?
#ls /sys/bus/usb/devices/usb?/speed

It has it opened as read-only, I'm guessing. You could open GPartEd and get more info on the problem with that drive. Are you mounted to that drive when you run gparted? I think you may have to unmount to perform any operations on it. True, but you can look at the warnings and info icons on the dri...

Welcome :welcome: In the grub4dos config file, just add a "pfix=nox" option to the vmlinuz line. This will boot puppy without starting X. I think most puppies come with "picocom" by default for tty serial communication. I think it uses VT100. You can view the CL options by typing...

Jafadmin

I think the Bionics also have 'picocom' installed by default. Anyways, mine all seem to have it ..

Hiya, Jafa! Long time no see. I thought you'd gone AWOL.....

Mike.

Had to take a break to get a gratuitous heart transplant. Finally back at the keyboard ..

Jafadmin

Can you find 'gtkterm' in the repo for your puppy version? You might also need 'setserial'.

Go to the Puppy Package Manager and just type 'serial' into the search bar.
