Network Topology

Virtual Topology

Xpra

  • Xpra is an open-souce muti-platform persistent remote display server and client for forwarding application and desktop screens.

 

  • It gives you remote access to individual applications or full desktopls.

How to run Xpra on your PC

Running Xpra with ssh
  • xpra start :50 --start=xterm --speaker=off (Server)
  • xpra attach ssh://USERNAME@HOST/50 (Client)
  • xpra attach :50 (Locally)
Running Xpra without ssh
  • xpra start --start=xterm --bind-tcp=0.0.0.0:10000 --html=on (S)
  • http://HOST:10000 (Web such as Firefox or Chrome on Client)
  • xpra attach tcp://Host:10000/ (terminal on Client)

 

Running Xpra server 

  • sudo netstat -anp | grep xpra

Accessing Xpra with web on client

  • http://192.168.100.1:10000 (on Debian VM )

Creating routes in Ubuntu 

  • Consider your physical pc as a router between real MikroTik and Virtual MikroTik
  • Create static routes to get rechability between MikroTik routers

GRE Tunneling

  • Generic Routing Encapsulation or GRE is a protocol for encapsulating data packets that use one rouing protocol such as RIP, EIGRP, OSPF inside the packets of another protocol.
OSPF or RIPv2
GRE

  • How to configure GRE Tunnel between MikroTik Routers

  • Check rechability between two mikroTik routers (Real and Virtual )
  • Create GRE Tunnel 
  • Assign Local Address and Remote Address correctly
  • Assign GRE Tunnel IP between two routers
  • Create routes on both MikroTik routers
