Troubleshooting TFTP Problems
Here are some things to check if you encounter TFTP problems.
• Verify that the /tftpboot directory exists and has read, write and execute (777) permissions with this
command:
ls -l /tftpboot
If necessary, use this command to create the directory:
mkdir /tftpboot
• If necessary, use this command to change permissions of the directory to read, write and execute:
chmod 777 /tftpboot
• Verify that the file /tftpboot/tftp_file_name exists and has read and execute permissions with this com-
mand:
ls -l /tftpboot/tftp_file_name
where tftp_file_name is the name of the firmware boot image specified by the Digi Device.
If necessary, use this command to change permissions of the file to read and execute:
chmod 666 /tftpboot/tftp_file_name
• Verify that the inetd.conf file is properly configured for tftp by displaying the file /etc/inetd.conf.
An entry similar to this should be uncommented:
tftp dgram udp something
where something will vary with each operating system.
For controlled TFTP access, make sure that the file /etc/tftpaccess.ctl exists and verify that it only
allows access to public directories. 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.
