chmod 666 /tftpboot/ftp_file_name
• Verify that the inetd.conf file is properly configured for tftp by display-
ing the file /etc/inetd.conf. An entry similar to this should be uncom-
mented:
tftp dgram udp something
where something will vary with each operating system.
• For controlled TFTP access, make sure that the file /etc/tftpac-
cess.ctl exists and verify that it only allows access to public directo-
ries. If this file is not present, tftp will allow full access. A sample file
is located in the directory /usr/lpp/tcpip/samples.
• Restart the inetd process with these two commands:
ps -ef | grep inetd
This will report back the inetd process number.
Kill -1 inetd_PID
Where inetd_PID is the process number for the inetd process
reported by the previous command.
Resetting PortServer TS 8/16 Configuration to Defaults
Use this topic to reset the PortServer TS 8/16 configuration to defaults.
Note: This procedure causes the PortServer TS 8/16 to lose all configuration
changes. If you have a complex configuration, see the cpconf command in the
Digi One/PortServer TS Command Reference for information on backing up
your configuration. The PortServer also resets to the DHCP default setting
and loses its IP address during the reset process. Use DPA-Remote to find
and configure your device. DPA-Remote can be found under Software on the
Software and Documentation CD or from www.support.digi.com under
Support Tools. You will need to re-assign an IP address after the reset and
reboot procedure.
