Daily Lab / POC Activities

Extramural:

• Successfully completed a globus-url-copy on lab the machine
• Corrected certificate error, details below. Note: Will need to submit a new certificate request
  

Renamed the server to match the name in the host certificate (command used: hostname new-servername.some.com)
to correct the following error:

• Command entered to simulate a large file transfer from a remote host to the local machine:

globus-url-copy -vb -dbg gsiftp://localhost/dev/zero file:///dev/null
Note: This transfer will run until you press ctrl+C

• Corrected Mapfile issue by adding a user name to the end of the mapfile and using that same user name to run a globus-url-copy.
  

Example of what it would look like if /etc/grid-security/grid-mapfile did not contain the correct information for a user attempting to run a globus-url-copy. I generated this error by removing the username from the end of the line in the /etc/grid-security/grid-mapfile
