General Discussion / Re: Folder permission

Well I can't see how they could CREATE subdirectories if they're not allowed to write to the parent directory .. because creating directories requires write permission.

Thanks Mark. Below is what i was trying to see if it is possible.

Parent folder: ~/test-parent

I don't want anyone to write to the parent folder, but they can create subfolders and write to those subfolders under test-parent. Please let me know if it is possible in anyways.

Usually the Linux installer will offer to do this for you (eg. In Ubuntu and derivative distros the installer will offer you "Install alongside Windows") .. shrinking the Windows partition automagically to make room.

Your other option would be to manually shrink the Windows partition from within Windows itself .. THEN to boot the Linux installation media and tell the installer to use the 'free space'.

Or the installer will usually also allow you to manually specify the partition scheme.

Which Linux distro were you thinking of using ?

Not 100% sure what you're asking...

If you're asking if it's possible to have a directory WITHOUT write permissions (by a particular users/groups), but have a subdirectory WITH write permissions .. yes.

Try it
Code: [Select]
mkdir ~/test-parent
mkdir ~/test-parent/test-child
chmod 555 ~/test-parent
Now see if you can create a file or folder in ~/test-parent and ~/test-parent/test-child

Or am I misunderstanding the question ?



You can delete these test folders (and contents) when you're done testing with:
Code: [Select]
sudo rm -r ~/test-parent

Kali is based on Debian .. the 3070 chipset (with the IDvendor:IDdevice string 148f:3070) is covered by the rt2800usb driver.

Instructions for rt2800usb in Debian can be found here:
https://wiki.debian.org/rt2800usb

I doubt this driver will get you the 'injection' you're probably after for aircrack-ng but it should get wireless working .. if 'injection' is your goal, please take this matter up on the Kali forum.

If you want the driver I posted in the earlier topic, just ask .. but again I seriously doubt it'll compile against recent kernels .. I'm happy to give you the source code, but I can no longer provide help compiling it because I:-
a) don't have a 3070 based card.
b) am not running anything with an old kernel (where it's liable to compile).
c) don't run (or understand the weird repository structure used by) Kali Linux.
d) have no use for (or wish to help people with) aircrack-ng for wireless cracking.

Also please don't report posts just to try get my attention .. that forum function is for reporting posts that you think may breach forum rules and/or good forum etiquette.
(in short, I'll attempt to help anyone on this forum where I can .. using the forums 'Report to Moderator' function with the note "no more replies?" just to get my attention is unnecessary, annoying, and is in itself a breach of forum rules and good forum etiquette)

Ok, thanks for that Mark, however, I will go the way of a fresh installation - I looked at the Clonezilla site, unfortunately their instructions are incomprehensible to my limited capabilities.

General Discussion / LINUX and parallel systems.
« Last Post by Anurakclark on October 18, 2019, 05:20:26 am »
Hello everyone,,

OK Linux looks good but there are so many. The node boards will do some fairly simple number crunching swap some data with neighbour boards via the usb ports and repeat the cycle. After a number of cycles the sever will want some data back. As its so simple I wonder which version would be best on the node boards as I dont want to use up RAM for unwanted functions. Also I had a look at using the Intel Atom dual CPU on the nodes.


I want to string a bunch of small PC boards together into a parallel computing system and wonder if linux will be a good system to use. I am considering a board like the rta nsw Jetway JNF77 VIA NANO 1.6GHz Mini-ITX Mainboard with 8GB sd memory and having the boards talking with each other through the USB ports and to a control PC via the gigabit network. The application is fairly simple, compute and exchange data etc, and requires lots of processors with lots of loacal memory. I usually program with visual c. Any suggestions would be helpful.

Thanks

Why not try cloning first, easy enough to reformat and fresh install if necessary.

Clonezilla LiveUSB would be my tool of choice
