~# hydra -l xxx -p xxx -M ips.txt -t 4 ssh
I tried apt-get remove and apt-get install but it still does the same thing.
So as a temporary sequential work-around I wrote a python script that calls it 1 record at a time and that worked
for line in fileinput.input("ips.txt"):
x = "hydra " + line.strip() + " -l xxx -p xxx -t 4 ssh
