\fB\-B\fP \fImax-block-size\fP
|
||||
Specifies the maximum permitted block size. The permitted range for
|
||||
this parameter is from 512 to 65464. Some embedded clients request
|
||||
large block sizes and yet do not handle fragmented packets correctly;
|
||||
for these clients, it is recommended to set this value to the smallest
|
||||
MTU on your network minus 32 bytes (20 bytes for IP, 8 for UDP, and 4
|
||||
for TFTP; less if you use IP options on your network.) For example,
|
||||
on a standard Ethernet (MTU 1500) a value of 1468 is reasonable.
