Parameters detail descriptions

-debian 7-12 : Debian 7 and later

-kali rolling/dev/experimental : Kali Rolling, Development and Experimental, "Kali Rolling" is most recommend obviously.

-centos 7 or 8/9-stream: CentOS 7 and later

-alpine 3.16-3.18/edge: Alpine Linux 3.16 and later, to keep updating to newest version, "edge" is most recommend obviously.

-windows 10/11/2012/2016/2019/2022:

Optional list of distributions:

  • Windows 10 Enterprise LTSC 22H2 for simplified Chinese and Japanese, 23H2 for English
  • Windows 11 Pro for Workstation 22H2 for simplified Chinese and Japanese, 23H2 for English
  • Windows Server 2012 R2
  • Windows Server 2016
  • Windows Server 2019
  • Windows Server 2022

Note: Windows 10 and 11 23H2 for English preferred to use base images of tiny10 and tiny11 which were developed and optimized by ntdev .

Installing Windows by using "bash InstallNET.sh -windows distribution number" supports IPv4/IPv6 dhcp or static, expanding current OS disk partition from default 15GB dd image to the actual capacity of the drive. Automatic setting steps of above must be executed after Administrator user login. For example, you can login to the newly installed system via VNC first if the router of upstream network supports only static configure method so that accessing server via RDP is unable yet.

All Windows dd images were re-packaged with incepted drivers which are necessary for cloud virtualizations and provided by Teddy Sun and hosting on https://dl.lamp.sh/vhd/ . Thanks and appreciates for his contributions, here are the github and blog pages of him:
https://github.com/teddysun/
https://teddysun.net/
https://teddysun.com/

-lang/-language "cn, en or jp": This option is to set language of dd images of Windows like: -windows 10 -lang "en", cn is simplified Chinese, en is English, jp is Japanese, default is en. It's not valid for Linux distributions.

-port "": you can pre-specify ssh port of system, range is 1~65535, this option is not valid for installing Windows, default is depended on the original system, if getting this value is failed, the value will fall back to '22'.

-pwd/-password '': you can pre-specify ssh password for target installing system. Native installation methods for Redhat series, Debian/Kali could be supported, not suitable for AlpineLinux and those OS which will be installed by "Overwriting Packaged Image Mode"(dd) method like Ubuntu, Windows and Redhat installations(only in environments of low memory capacity). A couple of apostrophe includes between the whole password is recommend, if there is one and more apostrophes in the password, you should use " '\ " to replace the original apostrophe to prevent it's could not be expressed and handled correctly in the shell! default is 'LeitboGi0ro'.

-hostname "": you can pre-specify hostname for the newly installing Linux system, the value with empty or includes special symbols except hyphens is not recommend. If the hostname of your original system is "localhost", empty or you want to assign it randomly(-hostname "random"), the expect format of the value is "instance-year, month, day of the server time-hour, minute of the server time. default is depended on the original system.

-dd/--image "DD image from a valid url": This parameter is for dd mode in KVM or XEN virtualization platform. This option is applicable for "Overwriting Packaged Image Mode".

For installing Ubuntu in any memory capacties, installing RockyLinux 8+ and AlmaLinux 9+ in low memory mode, installing Windows by using "bash InstallNET.sh -ubuntu/rocky/alma/windows", the middle handler is AlpineLinux, dd installation method of RockyLinux 8+, AlmaLinux 9+ and Windows may take a long time even up to 40 minutes or more if hard drive I/O of system is too low, wait patiently until installation finished.

Steps of DD any system that you want to:

The middle handling Linux system is Debian 12 with the following steps without any OS assignment:

bash InstallNET.sh -dd 'DD image download URL'

Servers based on physical hardware, Intel network adapter, kimsufi etc. : Change netboot to rescue mode, receive temporary username and password from mailbox, login rescue linux, execute:

wget -O- 'DD download URL' | xzcat | dd of=/dev/sda

Wait until downloading and unpackaging are all finished, change netboot to formal mode, exit from rescue Linux to the newly installed system:

reboot

-filetype "gz/xz": To determine DD file type, not only ".gz"(default) but also ".xz" can be supported.

-timezone "like Asia/Tokyo etc": It means assign timezone manually, if the format of the input parameter is incorrect or it's not supported by current operating system, the value will fall back to "Asia/Tokyo". If the parameter is not assigned, the value depends on the geo-location of guest's IP address, if you are using a proxy to connect to the server with ssh service, automatic timezone configuration may not suitable for you in this situation. This option is not valid for Windows.

-raid "0, 1, 5, 6 or 10": Test succeed on Debian 12, Kali rolling, CentOS 9-stream, AlmaLinux 9, RockyLinux 9, Fedora 38 with native installation method, raid 0, 1, 5, 6 or 10 disks raid partition recipes, not suitable for dd installation, raid 0 or 1 needs at least 2 disks, raid 5 needs at least 3 disks, raid 6 or 10 needs at least 4 disks, if your machine has only one hard drive or capacity of all drives are not the same or in a virtual environment, don't assign it!

-setdisk "a name of one disk or all": If your machine has 2 or more hard drives, and every hard drive want to format during the installation, you can assign -setdisk "all" to enable it, data is invaluable, you should deal with them carefully! or you can allow system to be installed on one disk like "vdc" or "/dev/sdb", This parameter is only suitable for Debian/Redhat series and conflicts with "-raid".

-swap/-virtualmemory/-virtualram "number, the unit is MB": Default is "0" which means no swap is allowanced, you can pre-specify a certain capacity of space on hard drive to enable swap for target system, for example " -swap '1024' " to distribute 1GB swap, not suitable for Raid, AlpineLinux, dd Mode.

-filesystem "ext4 or xfs": Default is "ext4", you can pre-specify a kind of file system for target system, only suitable for Debian/Kali.

-partition "mbr" or "gpt": Default is "mbr", you can assign "gpt" to format hard drive with GUID Partition Table, if the capacity of current hard drive is above 2TB, "gpt" partition recipe will be activated automatically, This is only valid for Debian/Kali, single hard drive formatting environment, not suitable for Raid.

--nomemcheck: Disable memory check by force so that you can install any OS on any size of the memory in target machine, whether installation will succeed is not guaranteed, this option is only for trouble shotting.

--cloudkernel: Replace formal Linux kernel to cloud kernel because numerous hardware drivers like printers, scanners, sound cards, usb controllers etc. which are not necessary in environment of virtual machines of Cloud Computing Platforms and these will be eliminated in the latter aims to help reducing space occupation of memory and hard drive. In situation of raid or dd(Windows) mode, installing cloud kernel will be disabled. --cloudkernel "0" is to disable installing Linux cloud kernel by force, --cloudkernel "1" is to enable installing cloud kernel by force. This option is only valid for installing to Debian 11+/Kali/AlpineLinux. Cloud kernel executing on some hardwares like Oracle Cloud arm64 servers will cause guest display in VNC be disabled, to avoid this, you may assign --cloudkernel "0" to switch to installing traditional Linux kernel by force. For virtualization of VMware and VirtualBox, installing cloud kernel will cause booting failed.

--motd: Enable to insert a set of modified MOTD(message of the day) scripts for a convenience to check executing status of a server when connecting by ssh shell, default is disabled, only available for Debian/Kali/AlpineLinux.

--bbr: Enable BBR(Bottleneck Bandwidth and Round-trip propagation time) for current kernel by adding parameters and values to "/etc/sysctl.d/99-sysctl.conf" including:

net.core.default_qdisc = fq
net.ipv4.tcp_congestion_control = bbr

to optimize the network environments of high latency and low bandwidth, only valid for Debian 11 and later.
Note: Module "tcp_collapse_max_bytes" is a self completion of Cloudflare, you need to download and apply patches by yourself otherwise this module will not be in effect: https://github.com/cloudflare/linux/tree/master/patches

Little tutorial: Installing XanMod on Debian

Introduce: XanMod series is an excellent third part mod for Linux kernel to improve network connectivity including applicating the patches of Cloudflare which we known on above, enhanced hardware compatibility etc. only for amd64 architecture CPUs .

Install gpg utility:

apt install gpg -y

Download, import and transform gpg key to binary file:

wget -qO - https://dl.xanmod.org/archive.key | sudo gpg --dearmor -o /usr/share/keyrings/xanmod-archive-keyring.gpg

Apply additional repository of "dl.xanmod.org" for apt:

echo 'deb [signed-by=/usr/share/keyrings/xanmod-archive-keyring.gpg] http://deb.xanmod.org releases main' | sudo tee /etc/apt/sources.list.d/xanmod-release.list

Refresh package dependencies:

apt update

Install xanmod Linux kernel, the differences from "v1" "v2" "v3" "v4" is the different optimizations for ISA (Instruction Set Architecture) of CPUs from each periods, you can visit https://xanmod.org/, title "x86-64 psABI level reference" to inquire or execute this script to confirm it: https://dl.xanmod.org/check_x86-64_psabi.sh .

apt install linux-xanmod-lts-x64v3 -y

Reboot the system:

reboot

To confirm the new kernel that we installed:

uname -a


--setdns: Only for Debian/Kali to change name server for Debian permanently is provided by "resolvconf", related configuration files has been written. you just need to logging in new installed system, and install "resolvconf":

echo "O" | apt install resolvconf -y
restart

to make changes validating!

--network "dhcp/auto" or "static/manual": Default to use DHCP to finish network configuration. If your cloud provider is a small or middle merchant, the network of your machine may be static so you need to add it. it is equal with add --ip-addr "" --ip-mask "" --ip-gate "", if you add this, don't distribute the following three items again! It must be added in the last of the command.

--networkstack "ipv4", "ipv6" or "dual": To specify one supported IP stack manually by reading related configurations instead of checking connectivity of IP stacks, "ipv4" is for IPv4 stack, "ipv6" is for IPv6 stack, "dual" is for IPv4 and IPv6 bi-stack. To make sure the parameter of corresponded stack must has specify configurations in system before assign it.

--ip-addr "IPv4 address": It must be added with --ip-gate and --ip-mask together, in this situation, --network "static/manual" is automatically assigned.

--ip-gate "IPv4 gateway": It must be added with --ip-addr and --ip-mask together, in this situation, --network "static/manual" is automatically assigned.

--ip-mask "IPv4 subnet musk": It must be added with --ip-addr and --ip-gate together, in this situation, --network "static/manual" is automatically assigned, can only accept prefix number transmit. IPv4 CIDR Calculator: https://www.vultr.com/resources/subnet-calculator/

--ip-dns "IPv4 DNS server": This one is only for static network configuration and default is 1.0.0.1 and 8.8.4.4, you can also change other IPv4 dns server like 8.8.8.8, 9.9.9.9, 4.4.2.2 etc to replace it. If the network of your machine is DHCP, don't assign it!

--ip6-addr "IPv6 address": It must be added with --ip6-gate and --ip6-mask together, in this situation, --network "static/manual" is automatically assigned.

--ip6-gate "IPv6 gateway": It must be added with --ip6-addr and --ip6-mask together, in this situation, --network "static/manual" is automatically assigned.

--ip6-mask "IPv6 subnet musk": It must be added with --ip6-addr and --ip6-gate together, in this situation, --network "static/manual" is automatically assigned, can only accept prefix number transmit. IPv6 CIDR Calculator: https://en.rakko.tools/tools/27/

--ip6-dns "IPv6 DNS server": This one is only for static network configuration and default is 2606:4700:4700::1001 and 2001:4860:4860::8844, you can also change other IPv6 dns server to replace it. If the network of your machine is DHCP, don't assign it!

--setipv6 "0 is disabled": Default will enable IPv6, if your machine is IPv4 stack and provided by Racknerd and Virmach etc. they will give IPv6 DNS for IPv4 stack server, the server will access to invalid IPv6 network for priority, not IPv4 first, you can remove all IPv6 modules force in new os by adding --setipv6 "0" to avoid the situation of above. This option is not valid for Windows.

--adapter "real network adapter interface name of the machine, like ens3, enp6s0 etc.": If the kernel is added parameter "net.ifnames=0" or "biosdevname=0", all different network adapters' name will be directed to the same like "eth0", "eth1" etc. If you know the the real name of the network adapter and want let them to replace "eth0", please input the correct value, if you are not sure the real name of it, don't assign it!

--netdevice-unite: This function has an opposite effect of --adapter "real interface name", it will add "net.ifnames=0 biosdevname=0" to the kernel to redirect all different network adapters' interface name to united "eth0", this one don't need to assign any value, I suggest you that before input it and start OS installation, you should backup the real name of the network adapter carefully!

--autoplugadapter: Only valid for Debian/Kali, the connection method of network adapter will be replaced from "allow-hotplug" to "auto" in /etc/network/interfaces. --autoplugadapter "0" is disabled by force, --autoplugadapter "1" is enabled, it's enabled by default. When add this, for multiple interfaces environment, if the interface which is configurated by "auto", regardless of it is plugged by internet cable, Debian/Kali will continuously try to wake and start up it contains with dhcp even timeout. Set up with "allow-hotplug(default setting by Debian/Kali installer)" will skip this problem, but if one interface has more than 1 IP or it will connect to another network bridge, when system restarted, the interfaces' initialization will be failed, in most of VPS environments, the interfaces of machine should be stable, so replace the default from "allow-hotplug" to "auto" for interfaces config method is a better idea, but it causes some server spending a long time to boot up(try to activate all internet adapters and waiting dhcp fatal time). Because the default configure method "allow-hotplug" will cause network adapter disconnected to the host permanently unless rebooting the system when executing "systemctl restart networking" so in order to avoid this situation, all configure method of valid network adapters will use "auto" instead of "allow-hotplug".

--fail2ban: Install and configure fail2ban to prevent from suspicious ssh port blastings. To reduce occupation of the memory, those servers which memory are less than 2GB will disabled automatically. --fail2ban "0" is disabled by force, --fail2ban "1" is enabled by force. This option is not valid for Windows.

-netbootxyz: Using netbootXYZ to install the OS that it's supported manually, VNC access for manipulation is necessary, make sure the memory capacity of the server is enough to accommodate the whole iso image for installing the target system. Only for AMD64/x86_64 architecture with BIOS firmware. ARM64/aarch64 architecture, UEFI firmware with any architecture could not be supported!

--allbymyself: Install OS supported by this script manually, must have VNC, this option is not valid for Redhat series.

-mirror "a valid DIST mirror url": OS install files resource, you can select one which nearest for actual location of your server to upspeed installation.

-architecture "32/i386 or 64/amd64 or arm/arm64": OS bit. Program will automatically detect and redirect the CPU architecture from your machine to new system which would be installed, if you aren't known it well, don't assign it!

Advanced usage, for example Debian 12 (recommend for servers which are locating outside of mainland China)

Japan: 

bash InstallNET.sh -debian 12 -mirror "http://ftp.riken.jp/Linux/debian/debian/"

HongKong: 

bash InstallNET.sh -debian 12 -mirror "http://ftp.hk.debian.org/debian/"

Australia: 

bash InstallNET.sh -debian 12 -mirror "http://ftp.au.debian.org/debian/"

Errors and solutions:

In some versions of CentOS 8 which are not subsumed into CentOS-stream are end of supporting by CentOS official, so the source is failure:

Failed to synchronize cache for repo 'baseos', ignoring this repo.
Failed to synchronize cache for repo 'appstream', ignoring this repo.

You first need to fix the source available and then execute this script.

cd /etc/yum.repos.d/
sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*

If script notices any error like in "# Check Dependence", please execute it again!

If you have enabled and assigned IPv6 address after server had been created in the website panel of some cloud providers like Oracle etc. but IPv6 is still invalid in the original system, you can try "dhclient" command to enable IPv6, the same as IPv4:

dhclient -6 "network adapter name"
dhclient -4 "network adapter name"

"InstallNET.sh" doesn't provide any third-part activation service for Windows, this function is only aim to assist you with researching, evaluating related features of Windows. "InstallNET.sh" only supports your server to install from Linux to Windows but it can't work well in Windows so that you have no more chance to use "InstallNET.sh" to install from Windows to Linux again.

"InstallNET.sh" is not responsible or liable if someone cause any illegal circumstance. You should assume any consequences by your own after executing this program includes: causing data corruptions without any backups, causing irredeemable operation failure of the server.

Features and updates:

  • "InstallNET.sh" will give you a clean, safe, official Linux system, and help you escape of your server providers' monitoring.
  • The operation is easy, several minutes installation will be complated.
  • Support install to Debian series, Redhat series.
  • Can also run in mainline version of other Redhat series(Oracle Linux 7+, VzLinux 8+) to install supported system.
  • Support major cloud providers, especially support Oracle Cloud ARM machine.
  • Detect the CPU architecture of current os and exchange correct architecture to new system automatically, you need not to add parameter '-version' at all to comfirm architecture manually.
  • Can handle boot menuentry items automatically of grub2 in different hardware platforms(AMD64 legacy / AMD64 UEFI / ARM64 UEFI) to make sure all supported boot file can be loaded correctly.
  • Support install from Linux(Debian series only) to Windows. details refer to "How to install Windows?" section.
  • Support IPv6 single-stack(have only IPv6 public address and IPv4 intranet routing) server like Vultr 2.5$ monthly plan, only for DHCP.
  • Support network auto configurations in bio-stack(have both IPv4 and IPv6 public address), after log into new system, you don't have to config IPv6 address manually, only for Debian, DHCP.
  • You can modify architecture, mirror, firmware, ssh port, password etc.
  • Friendly to low memory device, for Debian series, recommend RAM is above 512MB, for Redhat series, recommend RAM is above 2GB.
  • Ubuntu 22.04 has cancelled net boot start features, so this program don't support Ubuntu 22.04 and above reinstallation, source: http://archive.ubuntu.com/ubuntu/dists/jammy/main/installer-amd64/current/legacy-images/: The Legacy Ubuntu Server Installer is no longer available, initrd.gz and linux netboot file for arm64 architecture as also.
  • The Debian official mirror of South Korea http://ftp.kr.debian.org/debian/ is usually crashed down, so I changed recommend mirror as Jaist University https://www.jaist.ac.jp/index.html, for Japan is from https://www.riken.jp/, a science research organization, for America is from University of California, Berkeley: https://www.berkeley.edu/.
  • Completely modified Debian, such as support terminal files colorful displaying, permanently change dns server, disable expired certificates, add on a cute welcome introduction, pre-install many complements in preseeding progress, now enjoy a newly, comfortable, graceful debian experience!
  • Support grub2 boot file modify, it can switch Debian series to Redhat series or switch Redhat series to Debian series smoothly, in old version if you installed from Debian series to Redhat series, you can never switch to Debian series again.
  • Support xfs file system(only for Debian 9 and later), it's better than the old ext2 and it's the default option of Redhat series, the file system of raid 0 disk partition mode is ext4.
  • Detect if the machine is operating in mainland of China or outside and switch mirror automatically.
  • Support the parameter of '-port' to modify ssh port of Redhat series.
  • Detect the network of device is DHCP or static automatically.
  • For windows DD package, default compression method is "gz", if your package is ".xz", you can add parameter -filetype "xz" to decompress it.
  • Support Raid 0, to add parameter -raid "0", the validation need to be certificated.
  • Disable ntp clock setup for static network in Debian/Ubuntu installation otherwise it may cause static network failed.
  • Fix if input --ip-addr "" --ip-mask "" --ip-gate "", static network configuration may not valid.
  • Support config timezone automatically according to the geo-location of the guest's IP or determine an existed timezone parameter to config it manually is also be supported.
  • Concentrate all needed installation of dependences to inner command except "wget" because you need to download "InstallNET.sh" first.
  • Support Debian 12.
  • Update pre-install components, python2 to python3, vim-gtk2 to vim-gtk3 for support Debian 12.
  • Creat a new algorithm for checking effectiveness about IPv6, it's applied in 10-sysinfo for motd file in Debian and the main program "InstallNET.sh".
  • Because of boot menuentry configuration in grub file "grub.cfg" from RockyLinux 9 of official template of Oracle Cloud is different from other standard Redhat like os(version 7+) compeletely, so I creat a new algorithm for handle this and all of similar situation in future.
  • Update vim file modification for Debian 12.
  • Because of github.com and githubusercontent.com etc are banned by China, so I switich external files download sources which are necessary for Debian or Redhat like os example files for motd, firewall configurations etc. If your server is in mainland of China, the external files will be downloaded from https://gitee.com/mb9e8j2/Tools/, the other country/area will also be downloaded in this depository.
  • Try to enable IPv4 and IPv6 dhcp if possible.
  • Add necessary annotates
  • Set default installation os as Debian 12 and the value of architecture is empty instead of AMD64 because program will check architecture automatically.

Defects:

  • Not support for Ubuntu 20.04 and further versions for native installation method and replaced by dd cloud images because Canonical has deprecated the traditions which were also applied together with Debian by forcing users to download a huge several gigabytes iso image and then load it in its' fuckin Cloud-init instead of just two simply a hundred megabytes total network boot files by PXE boot, it runs in QEMU environment and CPU hardware virtualization must be demanded but most of VPS can't handle it well at all. Canonical has developed into a mature commercial company which intends to earn more money from major partners so they discrimes their personal users intentionally who are low-end clients in their conceptions certainly despite these users were their devoted fans since always and helped Canonical to make great achieves today step by step. According to the behavior of discarding a large amount of former precious Debian installer preseed heritances, Canonical would play a role as a guilty dictator like Apple.Inc in more areas and then violate the spirit of the universal free software finally.
  • For Redhat series 8, the minimum memory requirement is 2.5GB, for Redhat series 9, the minimum memory requirement is 2GB.
  • Because the syntax of grub1 in Redhat series 6 is different from other Linux version of grub1 or grub2 completely, so I removed support to CentOS 6 and Oracle Linux 6.
  • All system templates of GCP are not supported.

GroupPolicy import and export

This ".bat" script can only run in Windows. Although only one group-policy rule in Windows can be exported at a time and not support a global one and also have no GUI entrance to import another backuped group policy which exported from another computer. It can help you import or export GroupPolicy conveniently.

  • If you want to export group-policy rules. Folder which included group-policy files corresponds to current OS version strictly. Not support export rules which is different from current OS version.
  • Export operation is irreversible, be cautious to run it！
  • I provided a suggested rules file about Windows Server 2016.
