Verifying TFTP on a UNIX System

Use this procedure to verify that TFTP is working correctly on your UNIX host. 

This procedure, which uses a TFTP transfer of the Digi Device's boot image between two UNIX hosts, enables you to compare the size of the  boot image before and after it is transferred, enabling you to determine if TFTP is working properly. 

Procedure

  1. Access a root prompt on the UNIX host.
  2. Make sure that you are not in the /tftpboot directory.
  3. Enter this command:

    4. tftp ipaddress

    where ipaddress is the IP address of the UNIX host.

    A TFTP prompt appears.

  4. Enter this command at the TFTP prompt:

    5. tftp > get tftp_file_name

    where tftp_file_name is the name of the Digi Device's boot image in the /tftpboot directory.

  5. Enter this command at the TFTP prompt to exit TFTP:

    6. tftp quit

  6. Compare the size of the original file against the transferred file using this command:

    7. ls -l tftp_file_name /tftpboot/tftp_file_name

    If the file sizes match, TFTP is working properly. If they do not match or if the procedure fails before completion, see Related Documentation for information on troubleshooting TFTP problems.
