I just tested to connect to a Linux iSER enabled target, but I still get this error message at initiator side :
iscsid[1187]: 192.168.2.2 (iqn.2012-06.com.test:target1): failed to connect to 192.168.2.2 using ICL kernel proxy: ISCSIDCONNECT: Invalid argument
> as if my initiator did not understand the iSER command "ISCSIDCONNECT".
> How to be sure everything is correctly compiled with ICL_KERNEL_PROXY enabled ?
