Before responding to a request, the server attempts to change its current directory to homedir; the default directory is /tftpboot.
The use of tftp does not require an account or password on the remote system. Due to the lack of authentication information, in.tftpd will allow only publicly readable files to be accessed. Files may be written only if they already exist and are publicly writable. Note that this extends the concept of ``public'' to include all users on all hosts that can be reached through the network; this may not be appropriate on all systems, and its implications should be considered before enabling this service.
in.tftpd runs with the user ID and group ID set to [GU]ID_NOBODY under the assumption that no files exist with that owner or group. However, nothing checks this assumption or enforces this restriction.
