hm..

[tiger_at_laptop]:~%sudo cat /etc/iscsi.conf
tiger {
        TargetAddress=192.168.9.98
        TargetName=iqn.desktop:target0
}
laptop# kldunload iscsi

ok, after /etc/rc.d/iscsid onestart on laptop: 
laptop# iscsictl -L
Target name                          Target addr      State
iqn.desktop:target0                  192.168.9.98     Connection refused

I see the same behavior (connection refused) when I try 'iscsictl -A -h
192.168.9.98 -t iqn.desktop:target0' on desktop, with -h localhost all
work fine.
