2. Open the file
/etc/xinetd.d/tftp
and modify the parameter
server_args
to include -T
15000000. For example,
server_args = -c -s /tftpboot -T 15000000
3. The firewall that is built into some Linux systems might not allow the TFTP server to send and receive
information. You might first have to disable the firewall to allow these connections. If you are
experiencing firewall issues, change the firewall settings to allow connections on port 69 (the default
port for TFTP servers). See your firewall documentation for additional information.
If a firewall is enabled, disable it or modify the settings to allow the firewall to connect to the TFTP
port. To change the firewall settings, navigate to Applications>System Settings>Security Level, and
enter 69:udp in other ports.
