How to access Remote Desktop RDP openSUSE

Refferen from https://drive.google.com/file/d/1iAW0FSXUsTIwjEMI3lg_7EbCYCaQabbN/view 

1) Run the following command to install xfce if not installed (if installed already nothing will happen):

	sudo zypper install -t pattern xfce

2) Install and enable XRDP
	sudo zypper install xrdp xorgxrdp
	sudo systemctl enable xrdp
	sudo systemctl start xrdp

3) If your OS firewall is running. Allow RDP (TCP port 3389) through the firewall:
	sudo systemctl status firewalld
	sudo firewall-cmd --permanent --zone=public --add-port=3389/tcp
	sudo firewall-cmd --reload

** ถ้าเครื่องใช้ KDE, Gnome Desktop ไม่ต้องรันก็ได้
4) Set your user to use XFCE for RDP
	echo "xfce4-session" > /home/YOUR_USERNAME/.xsession

1.Network Interface

IP STATIC

vim /etc/sysconfig/network/ifcfg-eth0

//start ----------------

BOOTPROTO='static'

STARTMODE='hotplug'

ZONE='public'

IPADDR='192.168.1.102'

NETMASK='255.255.255.0'

//End ----------------

vim /etc/sysconfig/network/config ->DNS

NETCONFIG_DNS_STATIC_SERVERS="" -> Add IP DNS -> NETCONFIG_DNS_STATIC_SERVERS="192.168.1.1"

Restart service Network

wicked ifdown eth0

wicked ifup eth0

or use this command 

systemctl restart wickedd.service

systemctl status wickedd.service

ip addr -> check IP Address

ip route -> check IP Route

vim /etc/hostname -> hostname

abc.linux.com

2. Enable service sshd

systemctl enable sshd

systemctl start sshd

Edit vim /etc/ssh/sshd_config

# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin

# The strategy used for options in the default sshd_config shipped with

# OpenSSH is to specify options with their default value where

# possible, but leave them commented.  Uncommented options override the

# default value.
