# Linux reinstall useage
|
||
## Features:
|
||
- "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 Debian 8+, Ubuntu 14.04+, CentOS 6.
|
||
- Support major cloud providers, especially support Oracle Cloud ARM machine.
|
||
- You can modify architecture, mirror, firmware, ssh port, password etc.
|
||
- Friendly to low memory machine(recommend RAM above 256MB), <b>If your machine RAM is less than 768MB, before Debian 11 and above version installation, you may should not bash it with "-firmware" or "-firmware --cdimage" parameters because it won't let machine installation go into low memory mode and causes installation failed!</b>
|
||
- Ubuntu 22.04 has cancelled net boot start features, so this program don't support Ubuntu 22.04 and above reinstallation(source: https://www.reddit.com/r/Ubuntu/comments/uroape/is_there_a_netbootiso_equivalent_for_2204_jammy/).
|
||
- South Korea debian official mirror(http://ftp.kr.debian.org/debian/) is usually crashed down, so I change mirror of Kyoto University to replace it. Japan debian mirror is from https://www.riken.jp/, a science research organization in Japan. America debian mirror is from Massachusetts Institute of Technology: https://web.mit.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!
|
||
|
||
- Change name server for Debian permanently is provided by "resolvconf", related configuration files has been wittened. you just need to logging in new installed system, and run:
|
||
<pre><code>echo "O" | apt install resolvconf -y</code></pre>
|
||
to make changes validating!
|
||
## Defects:
|
||
- Debian preseeding process can only config one IP address, so to bio-stack machine(both have IPv4 and IPv6 address), after loggin to new system, you can only see IPv4 address are configurated, you have to config IPv6 address manually:
|
||
<br />
|
||
edit network interfaces:
|
||
<br />
|
||
<pre><code>vim /etc/network/interfaces</code></pre>
|
||
<br />
|
||
add ipv6 configurations:
|
||
<pre><code>iface ens3 inet6 static
|
||
address ::1
|
||
netmask 64
|
||
dns-nameservers 2606:4700:4700:0:0:0:0:6400</code></pre>
|
||
In above sample, you just need to change "::1" to your own IPv6 address which assigned by your cloud provider. "netmask" 64 is a typical value, "dns-nameservers" is from Cloudflare.com.
|
||
<br />
|
||
Save files and restart system.
|
||
- "InstallNET.sh" doesn't support pure IPv6 stack machine(have no IPv4 address, such as Vultr.com 2.5$/month plan).
|
||
## Download:
|
||
<pre><code>wget --no-check-certificate -qO InstallNET.sh 'https://raw.githubusercontent.com/leitbogioro/Tools/master/Linux_reinstall/InstallNET.sh' && chmod a+x InstallNET.sh</code></pre>
|
||
## Fully useage sample
|
||
<pre><code>bash InstallNET.sh -d/u/c(os type) 11(os version) -v 64(os bit) -port "your server port" -pwd "your server password" -a(auto install)/m(manually in VNC) -mirror "a valid url for OS image source" -firmware(with hardware drivers) --cdimage "cn"(this option is only for Debian)</code></pre>

# 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.
|
||
## Attentions
|
||
<ul>
|
||
<li>Compatible with all versions of Windows.</li>
|
||
<li>Only support the group-policy rules which exported by this script.</li>
|
||
<li>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.</li>
|
||
<li>Export operation is irreversible, be cautious to run it！</li>
|
||
<li>I provided a suggested rules file about Windows Server 2016.</li>
|
||
<li>You should run it on desktop.</li>
|
||
</ul>
