Hello,

How do I set a receive timeout on a UDPSocket? I’d like to timeout after  
5  
seconds. I tried this

sock.setsockopt(Socket::SOL\_SOCKET, Socket::SO\_RCVTIMEO, SockTimeout)

but I got an error.

./bin/…/lib/net/tftp+.rb:508:in `setsockopt': Invalid argument (Errno::EINVAL) from ./bin/../lib/net/tftp+.rb:508:in`download’  
from ./bin/tftp\_client.rb:81:in `main’  
from ./bin/tftp\_client.rb:98
