I have uploaded a new version (v0.95) of NodeShark. This version adds remote shell script execution feature allowing you to remotely execute any non-interactive shell script on your AllStar system with a single click. The shell script output is displayed in a command monitor window. The new feature includes a simple shell script editor that allows you to create, name, view, edit, and delete custom scripts from within NodeShark. You can create as many scripts as you like and they are added to a convenient drop-down list for single click execution. You can also import shell scripts created outside of NodeShark using other editors. Finally, v0.95 is the result of extensive code cleanup and highly improved error checking.
I have also updated the NodeShark User Guide to reflect the new features.
Currently, NodeShark directly supports multi-node to only a single AllStar system. The final feature I'll be adding prior to 1.0 is AllStar multi-site support (i.e multiple selectable configurations).
