-t, --tftpd-timeout <value> |
|
Number of seconds of inactivity before the server exits. This value
has meaning only when the server is started by inetd. In daemon mode,
the server never exits. Default is 300 seconds.
|
-r, --retry-timeout <value> |
|
How many seconds to wait for a reply before retransmitting a
packet. Default is 5 seconds. This can be overridden by the TFTP
client with the timeout option.
|
-m, --maxthread <value> |
|
Maximum number of concurrent threads allowed. Default is 100.
|
-v, --verbose[=value] |
|
Increase or set the logging level. No arguments will increase by one
the current value. Default is LOG_NOTICE, see syslog(3) for log
level. Valid value range from 0 (LOG_EMERG) to 7 (LOG_DEBUG).
|
--trace |
When verbose level is set to 7, this will output debug information for
each packet sent or received from the network.
|
--no-timeout |
|
disable timeout from RFC2349. This will prevent the server from
acknowledging the timeout option requested by the client.
|
--no-tsize |
|
disable tsize from RFC2349. This will prevent the server from
acknowledging the tsize option requested by the client.
|
--no-blksize |
|
disable blksize from RFC2348. This will prevent the server from
acknowledging the blksize request by the client.
|
--no-multicast |
|
disable multicast from RFC2090. This will prevent the server from
acknowledging the multicast request by the client.
|
--logfile <logfile> |
|
Log to a specific file instead of only syslog. nobody (or any user
used to run the server) must have permissions on the given
file. Assuming the file is /var/log/atftpd.log, simply run: "touch
/var/log/atftpd.log" and then "chown nobody.nogroup
/var/log/atftpd.log". When the server is ran in daemon mode,
/dev/stdout or /dev/stderr can be used.
|
--pidfile |
|
Write the PID of the server to the specified file. This may be useful
when automatically starting and stopping one or more instance of the
server.
|
--daemon |
|
Run as a daemon. Do not use this option if atftpd is started by inetd.
|
--no-fork |
|
When --daemon is specified, this option will prevent the server from
forking to background. It is useful for debugging purpose or
specialized usage.
|
--user <user[.group]> |
|
By default, the server change identity to the user nobody and group
nogroup. Specify an alternate user.group with this option.
|
--group <group> |
|
Alternate way of specifying the group. If group is specified with
--user and --group, the last option will be used.
|
--port <number> |
|
Specify the port on which atftpd listens. Useful when --daemon is
specified. Default is standard tftp port as determined
by getservbyname(3).
|
--bind-address <IP address> |
|
Specify the IP address which atftpd binds to. Useful when --daemon is
specified. Default is to bind to all interfaces. Only one address can
be specified, the server can only listen to one or all interfaces.
|
--mcast-ttl |
|
Specify the TTL to be used for multicast datagram. By default a value
of 1 is used. Note that TTL has a special meaning in multicast as it
is used to determine the scope of the packets. The value of 1 means
the packets dont leave the local network, see ip(4). Scope may also
be determine by the address as described RFC2365.
|
--mcast-addr |
|
Specify the IP address range to be used for multicast transfer. Format
string may comprise range and list of values:
"239.255.0.0-31,128-132,200".
Default value is "239.255.0.0-255". This address range is proposed in
RFC2365 for local scope.
|
--mcast-port |
|
Specify the UDP port to use for multicast transfer. Format string may
contain range and list of port number: "1758-2000,8000-9000". default
value is "1758".
|
--pcre <file> |
|
Specify a pattern/replacement file to use. This allow to replace
requested file name based on Perl Compatible Regular Expression. See
README.PCRE.
|
--pcre-test <file> |
|
Test a pattern/replacement file. When using this option, the server
will not start as usual but just read file name from stdin and
printout the substitution.
|
--mtftp <file> |
|
This will start a mtftp server thread for each valid entry in the
supplied file. See PXE specification for detail about mtftp. An
example file is provided in the source distribution.
|
--mtftp-port <port> |
|
Port the mtftp server shall listen to for incomming request.
|
--no-source-port-checking |
|
In some specific cases of networks using load balancer or other
equipment performing NAT (network address translation), some needs to
disable source port checking because port number as been translated. If
you want to use this feature, you must know why you need it and the
implication. Be aware that this option violate the RFC1350. This
option has effect only for non-multicast transfer.
|
--mcast-switch-client |
|
This option allow the server to proceed with the next multicast client
as soon as the current client timeout. When the current master client
fails to send an acknowledge (ACK) to the server, the server will send
an option acknowledge (OACK) to the master client with the field MC
(master client) set to false and send an OACK to the next multicast
client with MC set to true. Without this option, the server will retry
the current master client up to 5 times and then mark it done,
proceding with the next one.
|
-V, --version |
|
Show version of program.
|
-h, --help |
Show summary of options.
|
path |
This is the root directory used by the TFTP server. All requested
files from a TFTP client must reside in this directory. If not
specified, the directory defaults to /tftpboot. Since
atftpd run as the nobody user, the permission of the directory
must be set properly to allow file reading and writing.
