iSCSI Enterprise Target Daemon

## NAME

ietd - iSCSI Enterprise Target Daemon

## SYNOPSIS

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

## DESCRIPTION

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

## OPTIONS

- **-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)](/syslog/1.md).

- **-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.

## KNOWN ISSUES

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.)
