atftp - TFTP client (RFC1350).
atftp [options] [host [port]]
atftp can be used interactively or in batch mode to retrieve files from
TFTP servers. When used interactively, a summary of the commands can be
printed by typing 'help'. This TFTP client support all basic features from
RFC1350, RFC2347, RFC2348 and RFC2349. It also support multicast
implementation of RFC2090 and mtftp as defined in the PXE specification.
This program supports both the usual GNU command line syntax, with long options
starting with two dashes ('--') as well as short options. Some options are
usable in batch mode only, they have no meaning when atftp is use
interactively. A description of the options is shown below.
- -g, --get
- Non interactive invocation only. Instruct atftp to fetch a
file from a tftp server.
- --mget
- Non interactive invocation only. Used to fetch a file from
a mtftp capable server.
- -p, --put
- Non interactive invocation only. Instruct atftp to send a
file to a tftp server.
- -P, --password
- Give password to tftp server. This is a non-standard
extension to the atftp client necessary for Linksys routers and shouldn't
be used elsewhere.
- -l, --local-file
- Non interactive invocation only. The client side (locat)
file name to read or write. Must be used in conjunction with --get or
--put.
- -r, --remote-file
- Non interactive invocation only. The server side (remote)
file name to get or put. Must be used in conjunction with --get or --put.
- --tftp-timeout <value>
- Number of seconds for timeout of the client. Default is 5
seconds.
- --option <"name value">
- Set option "name" to "value". This
command supports exactly the same arguments as the interactive one. For
example, use: --option "blksize 1428" to configure block size.
Possible settings are:
--option "blksize disable"
--option "blksize 8"
--option "blksize 65464"
--option "timeout 1"
--option "tsize enable"
--option "tsize disable"
--option "windowsize disable"
--option "windowsize 4"
--option "multicast"
- --mtftp <"name value">
- Set mtftp possible options. Accepts the same options as the
interactive mtftp command. For example, use: --mtftp "client-port
76" to configure client side port to use.
- --no-source-port-checking
- See atftpd's man page.
- --prevent-sas
- Address the Sorcerer's Apprentice Syndrome situation as
requested by RFC 1350. This RFC requires repeated responses to a single
packet to be rejected. Thus a block will only get retransmitted on a
timeout. For backward compatibility, the default stays to ignore this RFC.
So blocks get transmitted on every request.
- --verbose
- Instruct atftp to be verbose. It will print more
information about what's going on.
- --trace
- This is useful for debugging purpose to display all packet
going to and from the network.
- -V, --version
- Print version.
- -h, --help
- Print a summary of command line arguments.
