php get iscsi output linux
7
I am trying to use exec(), system(), passthru() or anything to read in the output ofiscsiadm -m session, am not having much luck, and a little lost.
What I (think i) know:
- It is not a sudoers or permission problem, as the results are the same in a terminal or browser (and my sudoers is already successfully setup to use iscsiadm for login/out)
- Executing the following command from a terminal,
iscsiadm -m session > /tmp/scsi_sessyields an emptyscsi_sessfile
What I need to know:
- Where is the output getting sent, that I can not read it with a bash or php script but can see it in the terminal?
- How can I read the output, or get output sent somewhere that I can read it?
