Enable DHT on rutorrent

How can enable DHT permanently .If i do it from rutorrent gui it ddisables at restart.

nano /home/ username/.rtorrent.rc

i dont see it . http://prntscr.com/dfevcn
And on ftp i can’t find it.

then i would not worry about it. you should not need it tbh the torrent it self decides if its used and if its a private site your on then it will be disabled anyway

dht = on
added the line thanx
