UMobj

The UMobj suite of utilities support command line access to our Ceph Object Stores. In addition, each Object Store in UMIACS has a fully-featured web application that allows you access to your files from a web browser.

• https://obj.umiacs.umd.edu/obj
• https://gembox.cbcb.umd.edu/gembox

For UMIACS-supported linux machines, these utilities are already installed and should be available in the standard PATH.

Setup

Setting a few environmental variables containing your credentials you'll need to use for the Object Store is a good idea. When logged into the web interface, you can find these credentials on the user page. E.g. https://obj.umiacs.umd.edu/obj/user/

For example, if you use the bash shell, you can add something like the following to your .bashrc or .bash_profile.

export OBJ_ACCESS_KEY_ID="31sdfadDFAHFDN+344qOEIS"
export OBJ_SECRET_ACCESS_KEY="NDSMK3233adfahadflkkPDSH092DSJKDKDJKFDLSFLNK"
export OBJ_SERVER="obj.umiacs.umd.edu"

Or in tcsh you can do the following or add it into your .tcshrc.

setenv OBJ_ACCESS_KEY_ID "31sdfadDFAHFDN+344qOEIS"
setenv OBJ_SECRET_ACCESS_KEY "NDSMK3233adfahadflkkPDSH092DSJKDKDJKFDLSFLNK"
setenv OBJ_SERVER "obj.umiacs.umd.edu"
