import subprocess

def tail(filename: str) -> Generator[str, None, None]:
    proc = subprocess.Popen(["tail", "-F", filename], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
    while True:
        line = proc.stdout.readline()
        if line:
            yield line.decode("utf-8")
        else:
            break

for line in tail("/config/logs/openssh/current"):
    print(line.strip())
