I can't do brute-force attack to another than default ssh port on ncrack

I scanned a server and found that it's ssh port is = 1065 .I tried to login with putty, it works. But I can't do brute-force attack with nrack. I tried these commands but they doesn't seems to work. How can I specify another port than 22

root@yeni:~# ncrack -p ssh –user root -P pass.txt xxxx:1065
