Performing a tftp file transfer with a non-default blocksize against a tftp server that does not support the blocksize operation results in the following message: Error: falling back to blocksize 512 The command succeeds if the file being transferred does not exceed the server's file size limit. The message is misleading and uninformative since, in most cases, the transfer does indeed succeed. The command does return the correct status to the shell - it is the "warning" itself that is misleading. I propose printing out the following more informative message instead. Note: the block size option is not supported by the remote TFTP server. Without this option, transfers may be significantly slower and may be subject to transfer size restrictions.
(In reply to Mike Berger from comment #0) >results in the following message: > > Error: falling back to blocksize 512 I'm not seeing string "Error: " in the source: if (blksize != TFTP_BLKSIZE_DEFAULT) bb_error_msg("falling back to blocksize "TFTP_BLKSIZE_DEFAULT_STR); It should be printing "tftp: falling back to blocksize 512". Which looks good enough for me.
Okay. It looks like the "Error:" was coming from a wrapper in my environment.
