Opcje wykonania tftpd w konsoli

-a [address] [:port]

Specify the address and port to listen to when run in standalone mode with -l. By default, use the address and port in /etc/services.

 -B size

Do not transmit blocks larger than size, a number between 512 and 65464.

 -c

Allow new files to be written. The default permissions allow anyone to read and write the files. Use -p or -U to set other permissions.

 -l

Run tftpd in standalone mode, not from inetd. This mode ignores -t.

 -m file

Remap filenames based on rules specified in file. Each line in this file should contain an operation, an egrep-style regular expression (regex), and, optionally, a replacement pattern. If the regex matches any part of a filename, the operation is performed. The operation is specified as any of the letters shown in the next section, alone or in combination. Comment lines begin with #. See filename remapping rules below.

 -p

Use only normal system access controls for the user specified with -u (the tftpd username).

 -r option

Never accept the specified RFC 2347 option. The possible options are blksize, blksize2 (not based on a standard; like blksize but the block size must be a power of 2), tsize (transfer size), and timeout.

 -s

On startup, change root directory to the directory specified as directory on the command line. With -s, only one directory should be specified. Recommended for security and compatibility with certain boot ROMs.

Specify how long in seconds the server should wait for a new connection before terminating. Default timeout is 900 (15 minutes). If terminated, inetd spawns a new server when it receives a new request.

 -T timeout

Wait timeout microseconds before retransmitting the first packet.

Specify the name of the tftpd user. The default user is nobody.

Set the umask for newly created files. Without -p, the default is 0. With -p, it is inherited from the calling process.
