Is it possible to create user-privilleged directories from Windows to WSL directly?
I can create a folder from Windows, but it won't be the same as mkdir in WSL. For example, using Windows Explorer I create a new folder A
But, coming back to WSL, I can't cd A:
-bash: cd: A: Permission denied
Unless I do chmod 0761 * eventually. Isn't there a way to do that automatically?

I am using XAMPP on Ubuntu 20.04. It has been installed at the location opt/lampp/ location.
As usual before writing any code I am saving my php file within opt/lampp/htdocs location.
Now, every time I make changes to any file or want to save it I have to use the command line with sudo and obviously type my password again and again and again.
Could there be a way around this?
And not install xampp in root directory or but some other directory which is not within root directory?
Thank you.
I have found a solution to the problem. Now I can create files with in the specific folder of htdocs.
My location of installation of xampp was default one opt/lampp
Go the parent folder of htdocs that is /lampp and type
sudo chown -R $USER:$USER ./htdocs
Now go to the parent folder of ./lampp and type
sudo chmod -R 755 ./lampp/
Here what we basically did was change the permission to create folder and make changes to the file to the location where we have installed xampp.
We have VirtualBox (using vagrant) env , by mistake made an entry in /etc/security/limits.conf [with out having a root shell open:( ] and now I am unable to ssh (the connections drops immediately).
Previously we had one such scenario (limits done by someone else) , was able to fix using vboxmanage guestcontrol copyto CLI and was able to overwrite limits.conf and then ssh was allowed, this time around the vboxmanage CLI also hangs
Tried to open the VM in GUI and went to console and tried few options , but could not get to single user mode.
Since you already tried vbox cli command and the commands hang, it means even virtualbox cannot access the system or get a shell to open.
In this case you will have to bring up a ubuntu VM and use the qemu-nbd module to fix this. The steps are given below.
Bring up a very simple ubuntu vm using hashicorp’s bionic64 on the same host machine by executing the following steps.
mkdir bionic
cd bionic
vagrant box add hashicorp/bionic64
vagrant init
Open the Vagrantfile and change the config.vm.box = "base" to config.vm.box = "hashicorp/bionic64"
Also mount the folder in the host where the .vdi file for the VM is located by adding the following to the Vagrant file by adding the following line(replace the file path with the correct one corresponding to your system. Here /nbd2 will be created on the ubuntu machine and will contain the files including the .vdi file.
config.vm.synced_folder "/home/topcat/VirtualBox\ VMs/your_vm", "/nbd2"
Now do vagrant up
Once the machine boots up
vagrant ssh #to ssh as vagrant
sudo su #to become root
apt-get update #This will refresh the apt cache
apt-get install qemu
modprobe nbd (to check if the module is loaded successfully. Will exit without any output if it is installed)
qemu-nbd -c /dev/nbd1 "/nbd2/box-disk001.vdi" - (Here change the path to whatever you gave in the config.vm.synced_folder property)
mkdir -p /mnt/vdi-boot
mount /dev/nbd1p1 /mnt/vdi-boot
cd /mnt/vdi-boot/etc/security (This folder will have all the files as it were in your VM)
touch limits.conf (if the file is already there, delete it)
chmod 644 limits.conf
chown root:root limits.conf
open the /mnt/vdi-boot/etc/security/nsswitch.conf file and check if the following three lines are present
passwd: files
shadow: files
group: files
umount /mnt/vdi-boot (unmounts the mounted path)
qemu-nbd -d /dev/nbd1 (disconnects from qemu-nbd)
Exit the VM and start the VM
Open another shell and try to ssh. It should go through fine this time.
I am upgrading my WSL2 instance from Debian 10 to Ubuntu 20.04 LTS, because I need some newer packages.
How do I copy files and directories from Debian to Ubuntu, preserving the permissions and owner? (uid and gid are the same in the two Linuxes.)
Copying to windows first changes the permissions and owner of files.
explorer.exe also changes permissions and owner.
Preferably, I'd also like to avoid having to create a shared disk image file that I could mount from Debian and Ubuntu in turn.
I'd like something simpler, like accessing the second WSL instance directly from the first, e.g.,
$ cp -a <Debian>/myfiles/ <Ubuntu>/myfiles
Is this possible?
See also my similar question: How to access \wsl$\othercontainer\some\file from within a WSL container? where the short answer is:
sudo mkdir /mnt/othercontainer
sudo mount -t drvfs '\\wsl$\othercontainer' /mnt/othercontainer
ls -l /mnt/othercontainer/some/file
NOTE: It looks like symbolic links aren't supported.
Use tar. It will preserve all the file metadata.
In <Debian>, create myfiles.tar.gz:
tar zcvf myfiles.tar.gz myfiles
Copy myfiles.tar.gz to your windows drive e.g. with explorer.exe or with /mnt/c, and then copy myfiles.tar.gz to <Ubuntu>. In <Ubuntu>, untar it:
tar zxvf myfiles.tar.gz myfiles
I am trying to setup a script that will:
Connect to a windows share
Using LOAD DATA LOCAL INFILE, upload the two files into their appropriate db tables
Umount share
Situation:
I can currently vpnc into this remote machine
Problem:
I cannot
mount -t cifs //ip.address/share /mnt/point -o username=u,password=p,port=445
mount error(110) Connection timed out
I am attempting to do this manually first
Remote server is open to port 445
Questions:
Do I even need to vpnc in first?
Do I need to do route add for the remote ip/mask/gw after vpnc?
Thank you!
The mount.cifs file is provided by the samba-client package. This can be installed from the standard CentOS yum repository by running the following command:
yum install samba samba-client cifs-utils
Once installed, you can mount a Windows SMB share on your CentOS server by running the following command:
Syntax:
mount.cifs //SERVER_ADDRESS/SHARE_NAME MOUNT_POINT -o user=USERNAME
SERVER_ADDRESS: Windows system’s IP address or hostname
SHARE_NAME: The name of the shared folder configured on the Windows system
USERNAME: Windows user that has access to this share
MOUNT_POINT: The local mount point on your CentOS server
I am mounting to a share from \\10.11.10.26\snaps
Make a directory under mount for your reference
mkdir /mnt/mymount
Now I am mounting the snaps folder from indiafps02, User name is the Domain credentials, i.e. Mydomain in this case
mount.cifs //10.11.10.26/snaps /mnt/mymount -o user=Girish.KG
Now you could see the content by typing
ls /mnt/mymount
So, after performing your task, just fire umount command
umount /mnt/mymount
That's it. You are done.
no need to install "samba" and "samba-client", only "cifs-utils" using command
yum install cifs-utils
after that in windows share the folder you would like to mount in centos if you didn't do that already ("c:\interpub\wwwroot" in my case).
make sure you share it with a specific username whom your know the password for ("netops" in my case).
create a directory in centos in which you would like to mount the windows share in to ("/mnt/cm" in my case).
after that run that simple command as a root
mount.cifs //10.16.0.160/wwwroot /mnt/cm/ -o user=netops
centos will prompt you for the windows username password.
you are done.
When I open the Ubuntu windows store app and the bash command line (if I am not wrong?) comes up it's working directory is /home/username . I want to run a script which on my Windows is located in D:\University... . Can I do this and if so how?
I have only tried cd D:\ but I get " -bash: cd: D:: No such file or directory". I don't have any experience so far with Linux so I don't know if Ubuntu on Windows can only run in its own location or it can access all the files on my PC.
you can use mnt to access your drives.
root#user-pc: cd /mnt/d/your_destination_directory;
