On BB 1.6.0, tftp PUT hangs when a non-512 blocksize option is given: # tftp 10.203.133.6 -v0 -b1024 -p -rjunk -l/scratch/intern/core.gzip.669.s-1.gz tftp: timeout tftp: timeout tftp: timeout tftp: timeout tftp: timeout tftp: timeout tftp: timeout <--- Control-C out it. It works only with -b512 or no -b option is given. -Joe
