'lo again, all... and apologies if this is in the wrong place; no doubt, our friendly neighbourhood moderators will take care of it for me... :mrgreen:

I'm having issues with how some wireless networking USB dongles are working (or not).

I've had a look around the forums and elsewhere but I'm ...

In that text file it says to make sure and use the 'nl80211' driver with wpa_supplicant.

I have run into this issue before. So with the -D parameter with wpa_supplicant, I do:

Code: Select all

-D nl80211,wext

That solved my problem. Which sounds exactly like your problem.

'sdX' type drive designations are transitory. They are re-provisioned every time you boot the machine. There is NO guarantee they will stay consistent between boots.

It is ALWAYS recommended to use UUID's instead of 'sdX' designators. UUID's WILL remain consistent between boots. They will remain ...

UEFI boot will only work with GPT.

Don't think this is accurate. Just set up a hdd as follows:

-partition table = msdos
-part 1 = 100mb, fat32, boot, ESP, grub2 UEFI only
-part 2 = 20gb, ext3, linux, f96ce4

Drive is in a Dell E6430 laptop, bios/setup is configured ...

Jafadmin

In a situation where you have multiple OS's/partitions, etc. on a single disk, I always just mirror the disk to another disk using 'dd'. If I need to restore from it I just mount it to an additional mount point and copy off what I need.

Where sdX = disk to back up, and sdY = backup destination disk ...

Jafadmin

I always recommend booting by disk/partition UUID to alleviate these types of issues

Code: Select all

menuentry 'FossaPup64-9.5' {
	linux	/fossa/vmlinuz   root=UUID=47028e70-a6cf-43bc-807a-5ee09688d97c   psubdir=fossa pmedia=usbflash pfix=fsck
	initrd	/fossa/initrd.gz
}

By the way, a certain percentage of my acquaintances and friends do not trust developers who themselves do not use (all the time) the OS they develop or support. OK, let's soften the term a bit ;) ... It's not that they don't trust, but rather they are ...

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.

Jafadmin

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 ...

Jafadmin

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 ...

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 ...

Jafadmin

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 ...

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 ...

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

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 ...

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 ] && echo yes ...

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 ...

Jafadmin

It does floating point math and negative values

decx -89.1 T 32
-2851.2

decx -89.1 LT 32
0

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 ...

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 ...

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, "PupsaveDir" is the folder ...

If using LotsaLuks:

place as the other puppy boot files, and mount it. (name the file something simple for now)
2) copy everything from the ...
