+# Ubuntu Overssh Reinstallation
+
+If your ISP/Datacenter dosn't provide standard or trusted iso for your server. Get ugly server from it with installed version of Ubuntu server.
+
+I have same situation installed ubuntu has bad partition table or huge list of stupid package installed. Datacenter network is my primary concern or it's really cheap price but administrators dosn't care. What should i do? That's my way to solve this issue easily.
+
+Ask them to install ubuntu server what ever is it. re install it over ssh.
+
+Create your own netiso and reinstall it over ssh. You can partion yor server as you desire. And set more configuration using [ubuntu preseed](https://help.ubuntu.com/lts/installation-guide/armhf/apbs02.html) just over ssh; no kvm/ipmi/vnc required.
+
+### Requirement
+
+1. Installed ubuntu version on server via ssh access
+2. Clone this repo to your server
+3. Copy `config.sample` to `config` file and edit field by field exactly:
+
+```
+#!/bin/bash
+
+# country
+COUNTRY='IR'
+
+# network: check network before create iso file
+INTERFACE_DEV='eth0'
+INTERFACE_IP='10.1.1.100'
+INTERFACE_NETMASK='255.255.255.0'
+INTERFACE_GATEWAY='10.1.1.1'
+INTERFACE_NAMESERVERS='4.2.2.4'
+
+# preseed file: upload created preseed.cfg to your own host before reboot system
+PRESEED_URL="http://10.1.1.2/preseed.cfg"
+
+# ssh installer password
+PASSWORD="tHISiSpASSWORD"
+
+# hostname and domain
+HOSTNAME="${INTERFACE_IP//\./\-}-$COUNTRY_LOWER"
+DOMAIN="servers.aasaam.net"
+
+# lowercase of country code dont change it
+COUNTRY_LOWER="${COUNTRY,,}"
+```
+4. Upload your `preseed.cfg` file to your own host.
+
+#### Clone repository
+```
+cd /tmp
+git clone https://github.com/mhf-ir/ubuntu-overssh-reinstallation.git
+cd ubuntu-overssh-reinstallation
+```
+#### Config
+See `config.sample` and change it. Carefull about your network settings. It's can hold your server until get new kvm/ipmi/vnc to restore the ssh again.
+```
+cp config.sample config
+vim config
+```
+#### Download network mini iso from ubuntu website
+```
+wget http://archive.ubuntu.com/ubuntu/dists/xenial/main/installer-amd64/current/images/netboot/mini.iso
+```
+#### Build iso
+Remember you must do as root user
+```
+./create-iso.sh
+...
+Your network iso is ready '/tmp//ubuntu-overssh-reinstallation/ubuntu-overssh-reinstall.iso'
+```
+#### Update grub imageboot
+Remember you must do as root user also
+```
+./grub.sh
+...
+Your password is tHISiSpASSWORD
+```
+#### Reboot
+```
+reboot
+```
+#### Get ssh
+Wait it until boot to iso complete and install require packages then
+```
+ssh installer@10.1.1.100
+```
+#### Continue installation of ubuntu
+
+---
+This script test on Ubuntu 16.04 Server.
