Cannot register service: RPC: Unable to receive; errno = Connection refused
 

I have a program that was working fine on Ubuntu 9.10 64-bit.

But I shut down the machine to install more RAM, and after I booted it up and tried running the program, I got this error:

I saw this error before, and it was because portmap was not running. But this time, after I started portmap and re-ran the program, I still got that error. :scratch:

What's the program - what do any relevant logs say?

I had to do a "sudo ufw disable" and then re-run portmap to get the program to work, even though I had already checked the firewall and it said it was disabled.
