Hi, Britgirl, Thank you for your reply. I don’t know what product is installed on the EC2 instance. I downloaded the nomachine_4.4.6_7_x86_64.rpm from https://www.nomachine.com/download/download&id=5, which seems to be the only choice for Linux. Then I ran rpm -i nomachine_4.4.6_7_x86_64.rpm to install it on the EC2 instance. The results returned from /usr/NX/bin/nxserver –status are as follows:
NX> 161 Enabled service: nxserver.
NX> 162 Cannot find X servers running on this machine.
NX> 162 Connections to the physical display are not possible.
NX> 161 Enabled service: nxd.
I read the webpage https://www.nomachine.com/AR10K00710. You know what? Yes, there are a lot of articles in internet, but they are all TOO OLD, including this one. Things are changing all the time drastically in Linux. To be specific, the very first command of that article “sudo yum install xorg-x11-server-Xvfb” doesn’t work. I was prompted:
Loaded plugins: aliases, amazon-id, changelog, kabi, langpacks, rhui-lb, tmprepo, verify, versionlock
Loading support for Red Hat kernel ABI
No package xorg-x11-server-Xvfb available.
Error: Nothing to do
So, could you please run the instructions again in Amazon EC2 instance yourself and update that webpage accordingly? Today is Jan 22, 2015. The RedHat used in EC2 is version 7 (codename: Maipo), not 6 any more.
I’m using t2.micro instance type, it is in free tier (and therefore crippled).
