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