Windows CLI get file from Internet (like wget or curl)

CMD: (bitsadmin is depricated)

 bitsadmin /transfer <DownloadJobName> /download /priority normal http://example.com/example.txt C:\example.txt

BITSAdmin tool does not provide an option to ignore certificate errors

PS: 

Invoke-WebRequest -Uri http://example.com/example.txt -OutFile C:\example.txt

Start-BitsTransfer -Source http://example.com/example.txt -Destination C:\example.txt

Invoke-WebRequest -Uri https://example.com/example.txt -OutFile C:\example.txt -SkipCertificateCheck

(to skip certificate errors)

Access files between WSL instances

 Preamble:

C:\Users\Ivan Popov>ver && wsl --list
Microsoft Windows [Version 10.0.19041.985]
Windows Subsystem for Linux Distributions:
Debian (Default)
kali-linux

ToDo: access files in $HOME on Debian wsl instance from kali-linux wsl instance 

Dunno how (and don't care actually) rootfs is mounted in Windows, but files are located here: 

C:\Users\%USERNAME%\AppData\Local\Packages\TheDebianProject.DebianGNULinux_76v4gfsz19hv4\LocalState\rootfs\home

(TheDebianProject.DebianGNULinux depends of installed distro)

In WSL current disk partitions are already mounted under /mnt/Disk_Letter

To access my debian_home from kali I executed: 

echo "sudo mount -B /mnt/c/Users/My\ Current\ WinUserName/AppData/Local/Packages/TheDebianProject.DebianGNULinux_76v4gfsz19hv4/LocalState/rootfs/ /mnt/deb/
" >> ~/.bashrc

[fstab entry should be in format /old_dir /new_dir none bind but for some reason didn't work]

The result:

$ls /mnt/deb/
total 620

Hyper-V nested virtualization (for EVE-NG примерно)

 Run PowerShell as Administrator

Set-VMProcessor -VMName "VirtualMachineName" -ExposeVirtualizationExtensions $True

VirtualMachineName - the  name of previously created VM on which we want to start nested virtualization

Windows files copy

RoboCopy (part of Resource Kit 2003) - console only, multithread mode with /MT:nn (1< n >128) - very good tool - mirror option, logging, retry N and so one. Full list of avialable options HERE
RichCopy - simple but with GUI. Nothing special, just doing his job well
vXCopy - simple and light. Max threads = 15
native utility xcopy - /c (continue if error) /z (restartable mode via Network), ACL/NFTS permissions aware- sux coz only 1 thread. Good for scripting
copy - native for cmd shell. Missing (or tricky)  ability to copy entire subdirectories

Robocopy

Задача: да се мигрират redirected user folders(Desktop & My Documents) на друг сървър и storage.
Варианти: rsync for Windows, но това искаше иснталации и на двете машини (source & destination) и native за Windows - robocopy.
Сериозните опции са /mir и /copyall
Същественната разлика м/у /mir и /copyall, е че /mir изтрива съдръжанието на destination folder-a и го замества със съдържанието на source folder-a, докато при /copyall ако има промени в source folder-a при стартирането ще се отразят в destination folder-a без да се загубят промените които м/у временно са възникнали в destination folder-a
Примерно:
Robo_source : file1, dir1
Robo_dest: file2, dir2
след robocopy \\server1\Robo_source \\server2\Robo_dest /mir /e /tee съдържанието на Robo_dest == file1, dir1;
докато след robocopy \\server1\Robo_source \\server2\Robo_dest /copyall /e /tee съдържанието на Robo_dest == file2, dir2, file1, dir1;
Useful switches:
/z - restartable mode
/save:job.file - run and save command + swtiches in job.file.rcj (/save:job.file.rcj трабва да е най-накрая в списъка с допълнителните ключове - т.е. записва се всичко до /save:xxx, но не и след него). Създава се файл: job.file.RCJ
/save:job.file /quit - just save command + switches (do not run anything)
/job:job.file - read from job.file.rcj and run what you read
/mon:N - monitor for N changes in Source_dir
/mot:N - monitor in N min for changes in Source_dir
Examples:
1. full mirror
robocopy \\server1\Robo_source \\server2\Robo_dest /mir /e /tee
2. Update Robo_dest with changes in Robo_source (e.g. differential)
\\server1\Robo_source \\server2\Robo_dest /copyall /e /tee
3. Just monitor for 3 changes every 3 minutes
\\server1\Robo_source \\server2\Robo_dest /mon:3 /mot:3 (?!)- на теория трябва само да следи за промени ама май направо си ъпдейтва Robo_dest с промените в Robo_source

П.С. версиите до W2k8 не "реагират" при промяна на атрибутите за NTFS permissions, но във Vista и Windows 2008 (R2) вече има допълнителен ключ - /secfix
MS графичен фронт-енд
Robocopy записва в EventViewer-a какво се случва, но по-юзъбъл за мен е mail notification

What is my OS

Каква е версията на OS на машината на която съм се логнал ?
Linux:
uname -a -- kernel version, 32/64 bits
lsb_release -a
cat /etc/*issue
cat /etc/*-release
cat /etc/*_version
cat /proc/version
*BSD:
uname -a
Solaris
showrev -a
HP-UX:
uname -r -> това дава release identifier и после по този release identifier тук примерно
IOS/XOS (Extreme Networks) :
show ver
NT based Windows (7/Vista/2003/XP/2000/NT4):
Run/cmd -> msinfo32
Run/cmd -> winver
Run/cmd systeminfo | find /i "System Type:"

Винаги съм смятал, че Debian е най-sexy *nix дистрибуция, но това направо ме изуми: http://goodbye-microsoft.com/
