Specifies the default number of seconds to wait for a reply
before retransmitting. The default is 5 seconds, which is a common value
for most RADIUS clients. If the destination RADIUS server is at the end of
a distant or saturated link, you may want to set this to 10 or 20 seconds.
Can be overridden for an individual host inside its Host
clause.
# It is a poor link, wait 15 seconds before retransmission
RetryTimeout 15
