telnet: Unable to connect to remote host: Connection refused

[weWillGetThere]

I've tried telnet localhost bgpd in terminal, xterm, and the mn example sudo mn, all of them succeeded.
However, when I ran this command on a project that was slightly modified based on BGP Path Hijacking Attack Demo, the following error occurred:

Connecting to shell
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused

Then I ran pingall, which succeeded in the mn example, to get things below:

Did you debug this further to see what is up with the BGP hijacking demo?
