This seems to be a duplicate of #19

Hello, I have corrected it by placing an exception in the get_max_udp_datagram_size() method in tftpserver.py file as follows:

def get_max_udp_datagram_size():
"""Retrieve the maximum UDP datagram size allowed by the system."""
try:
val = subprocess.check_output(['sysctl', '-n', 'net.inet.udp.maxdgram'])
except Exception as err:
val = subprocess.check_output(['sysctl', '-n', 'net.core.rmem_max'])
return int(val)

We noticed that syctl does not get this system variable net.inet.udp.maxdgram, so we add the one that in my case (ubuntu server) finds: net.core.rmem_max

Regards,
Franklin
