But not today
I have a deadline to complete a penetration test and once again I am unable to connect to one of my AWS EC2 Ubuntu instances.
I had to take extra steps to update all packages on the system because for some reason some were held up. But that didn’t solve the problem in this particular case.
When I look at the connection information for this instance it says TCP not RDP.
There’s something strange going on here and I’ll find out eventually, but not today because I have other things to do.
I just wish someone at AWS or Canonical could take a closer look at what’s going on and come up with a safer, more reliable out-of-the-box option. Or maybe xrdp could do this instead of using the default certificates on the system and TCP instead of RDP – or is RDP the problem?
I don’t know. Further research is needed.
After updating the packages and blocking my network on everything except my incoming IP on port 3389, I just get a black screen when trying to connect via xrdp.
Follow for updates.
