The rOCCI Client

The OCCI gem includes a client you can use directly from shell with the following auth methods: x509 (with --password, --user-cred and --ca-path), basic (with --username and --password), digest (with --username and --password), none. If you won't set a password using --password, the client will ask for it later on.

Create a proxy with VOMS extension

$voms-proxy-init --voms fedcloud.egi.eu --rfc --dont_verify_ac
Enter GRID pass phrase for this identity:
Contacting voms1.egee.cesnet.cz:15002 [/DC=org/DC=terena/DC=tcs/C=CZ/O=CESNET/CN=voms1.egee.cesnet.cz] "fedcloud.egi.eu"...
Remote VOMS server contacted succesfully.


Created proxy in /tmp/x509up_u504.

Your proxy is valid until Sat Jun 14 01:09:06 CEST 2014
