ietd - iSCSI Enterprise Target Daemon


ietd [-c configfile] [-d debuglevel] [-f] [-g GID] [-h] [-a address] [-p port] [-u UID]


The ietd program implements the user level part of iSCSI Enterprise Target software for building an iSCSI storage system on Linux.


-c filename, --config=filename
Specify configuration file, default is /etc/ietd.conf
-d debuglevel, --debug=debuglevel
Turns on debugging. Logging goes to /var/log/syslog via syslog(1).
-f, --foreground
Act as a normal application which uses a console.
-g GID, --gid=GID
Specify running group id, default is current gid.
-a address, --address=address
Specify on which local address the server should listen, default is any.
-p port, --port=port
Specify on which port the server should listen, default is 3260.
-h, --help
Display help message on command line options.
-u UID, --uid=UID
Specify running user id, default is current uid.

Task attributes is incomplete (all tasks are treated as if they have the SIMPLE attribute.)
SCSI task management is incomplete.
NOP-In is incomplete.
The target never sends a NOP-In of its own accord.
Header and Data Digest in a discovery session are not implemented.
Out-of-memory situation leads to the system crash (There are still some out-of-memory bugs.)
