Calculate and Verify the MD5 Checksum for a File on a Client Workstation

About this task

Perform this procedure on a Unix or Linux machine to verify that the software files downloaded properly. The MD5 checksum for each release is available from Extreme Networks Support portal.

Procedure

  1. Calculate the MD5 checksum of the downloaded file:

    $ /usr/bin/md5sum <downloaded software file name>

    Typically, downloaded software files are in the form of .voss files.

  2. Verify the MD5 checksum of the software suite:

    $ more <md5–checksum output file>

  3. Compare the output that displays on the screen. Ensure that the MD5 checksum of the software suite matches the system output generated from calculating the MD5 checksum from the downloaded file.

Example

Calculate the MD5 checksum of the downloaded file:

$ /usr/bin/md5sum 5420.8.4.0.0.voss
d83cd61e0b115c83aca0c52c9dd5eb0e 5420.8.4.0.0.voss

View the MD5 checksum of the software suite:

$ more 5420.8.4.0.0.md5
