with no other arguments than the hostname? Could you check to see if you get an 
error message sent do

I ran ./check_nrpe -H x.x.x.x
CHECK_NRPE: Socket timeout after 10 seconds.

I then ran ./check_nrpe -H x.x.x.x -n

NRPE v2.5.1

Do you know if I need tcpwrappers installed if i want to run it under inetd.conf
