This document references XRDP Tip:how to reconnect to the existing session while using the XRDP package from Ubuntu Repository
The first connection to remote Desktop is the port at which the connection is observed:
Then run:
sudo vim/etc/xrdp/xrdp.ini
Insert under [XRDP1]:

lib=libvnc.so
username=ask
password=ask
ip=127.0.0.1
port=5910
Where 5910 is the port number observed just

It is very convenient to configure ADSL In Ubuntu. You can configure sudopppoeconf all the way. Then run the pondsl-provider command to start the dial-up and use the manual poff to disconnect the dial-up connection. In addition, we can use the plog command to view the connection log information. However, I recently encountered a particularly strange problem. Each time the last time, generally 4 ~ 5 minutes, sometimes 2 ~ In 3 minutes, the network is disconnected. You can use the pondsl-provider

Because it's for the client, "node" here is the broker.public Boolean Ready (node node, long Now) is the connection to the specified Node that has been created and can send the request. If the connection is not created, create a connection to this node.Public long Connectiondelay (Node, Long) is based on the connection state and returns the time to wait. There are three states of connection: disconnected, connecting, connected. If i
