Novell-tftp Parameters
Description
The IP address that is used for all TFTP communications. If a value is not given
here, the service tries to detect one.
This value is most useful for multihomed servers.
By default, this parameter is commented out.
This value determines the size of the data block used by the TFTP server to
transmit and receive data to and from a client. Valid values are between 512
and 4428.
For ethernet networks, this value should be 1428.
For token ring networks, this value can be 4428, but only if you are sure there
are no ethernet segments; otherwise, use 1428.
Older TFTP clients might be restricted to 512 bytes, the original transfer block
size before the adoption of RFC 2348. The Novell TFTP server is compatible
with these clients.
By default, this parameter is commented out.
This is the amount of time (in seconds) that the TFTP server waits for a client to
acknowledge before resending a packet. However, because the TFTP server
uses an adaptive algorithm to calculate the actual timeout interval, this value is
only used as an initial value. It may increase or decrease, depending on the
performance of the network.
This value is only a default. It can be changed at the request of a client. See
RFC 2349.
Valid values are 1 through 60.
By default, this parameter is commented out.
TFTPDirectory is the directory where the TFTP server can store and retrieve
files. All paths submitted to the TFTP server by clients are assumed to be
relative to this directory.
Because TFTP has no security, it is suggested that you not place files with
sensitive information in this directory, and that you place a space quota on it.
The TFTP server does not load if this directory does not exist.
By default, this parameter is commented out.
This tells the TFTP server whether to allow users to place new files on the
server. Setting this variable to 0 (the default) makes the TFTP server more
secure by not allowing users to place new files on the server. The other option
is 1, which allows users to place new files on the server.
This tells the TFTP server whether to allow users to overwrite existing files on
the server. Setting this variable to 0 (the default) makes the TFTP server more
secure by not allowing users to overwrite files on the server. The other option is
1, which allows users to overwrite files on the server.
TFTPAllowWrites must be set to 1 in order for the AllowOverwrites parameter to
be recognized.
