I previously had a dev version of deluged installed on this server; that has been removed and the 2.1.1 version of deluged is now installed (I used pip)
Deluged won't start and I can't figure out what is preventing deluged from running on the port I prefer...deluge-web is starting fine, but deluged is reporting:
Cannot start deluged, listen port in use.
Check for other running daemons or services using this port: [my preferred port]
Telnetting to said port is refused:
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused
netstat returns nothing on this port
ss returns nothing on this port
there is no other deluged process running
there is no entry in /proc/net/tcp corresponding to [my preferred port]
HOWEVER...if I change the port in core.conf, deluged is fine.
