TFTP uses simple checksum techniques to detect if a file is actually corrupted in which case it is rejected. Therefore, for TFTP, the use of UDP at the transport layer is desirable because the low overheads and latency outweigh any reliability concerns. Many text files that are used to configure routers will fit into a single typical segment, so the issues of ordering are greatly reduced. TFTP is a cut-down version of FTP, designed so that a TFTP server can be hosted within a device such as a router without requiring excessive processing and memory resources. TFTP was designed as a lightweight file transfer mechanism primarily used for transferring short configuration files to routers and other devices, typically over a short dedicated link or at least within a LAN environment. Users can only PUT (drop) files where they have remote WRITE access. TFTP ignores the rest of the security string. That is, the files must be secured “Nxxx”. Users can GET (retrieve) only files that grant all users remote READ access. The TFTP server on the remote system sets the restrictions on which files users can retrieve, as well as restrictions on storing files. The files remote users are allowed to retrieve from a remote system are typically secured for public access that is, anyone on the network can read the files. TFTP does not provide any mechanism for users to logon to the remote system with a userid and password and verify which files they can access. The HP TFTP client is used to transfer public files to and from a remote system.įiles can be transferred to or from any system on a network that has a TFTP server that accepts requests from the TFTP client. Remote TFTP clients are used to transfer public files to and from an HP Nonstop Server host system's TFTP server (TFTPSRV).
