Problem: ESG WGet scripts require a my proxy cert. The myproxylogon tool requires a gui to create my proxy cert. Some users cannot run this as they have a headless type environment.

User: end user

Solution:

I was trying to reproduce a wget script error for an end user and I was unable to run the two commands from our help page:

$ wget http://www.earthsystemgrid.org/webstart/myProxyLogon/MyProxyLogon-ESG.jar -O $HOME/.esg/MyProxyLogon.jar
$ java -jar $HOME/.esg/MyProxyLogon.jar -u nhook -h vetswebprod.ucar.edu -p 7512

The following exception is thrown:
