SYNOPSIS

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