I'm trying to learn and setup iSCSI on my server at home, but I don't
have much luck so far.
I can run a discover (and almost anything else):
----- s n i p -----
celia:~# iscsiadm -m discovery -t isns
[...]
192.168.69.8:43070,1 iqn.2011-12.com.bayour:storage.debian.lenny.64
[...]
----- s n i p -----
I have setup the iface (preparing for a multihomed machine):
----- s n i p -----
celia:~# iscsiadm -m iface
default tcp,default,default,unknown
iser iser,default,default,unknown
bnx2i bnx2i,default,default,unknown
iface0
tcp,00:21:97:8c:8f:5f,default,iqn.1993-08.org.debian:01:97d0448a2b3c
celia:~# iscsiadm -m iface -I iface0
iface.iscsi_ifacename = iface0
iface.net_ifacename = default
iface.hwaddress = 00:21:97:8c:8f:5f
iface.transport_name = tcp
iface.initiatorname = iqn.1993-08.org.debian:01:97d0448a2b3c

But when i try to login to the target, it fails:

Running iscsid in debug mode, I see some very strange output when
starting up:
----- s n i p -----
celia:/etc/iscsi# ps | egrep 'iet|iscsi|isns'
20218 ? Ssl 0:00 /usr/sbin/isnsd -a 192.168.69.8 -b
192.168.69.255
20238 ? Ss 0:00 /usr/sbin/ietd --address=192.168.69.8
celia:/etc/iscsi# iscsid -f -d8 2>&1 | tee /tmp/x
[...]
iscsid: Cannot resolve host . getaddrinfo error: [Servname not
supported for ai_socktype]
iscsid: cannot resolve host name
iscsid: destroying session
[...]
----- s n i p -----
However, I can clearly see (in /tmp/x) that it - iscsiadm - is actually
connecting, there's
"movement" in iscsid). This keep repeating:
----- s n i p -----
iscsid: thread 0887b9d4 removed from poll_list
iscsid: exec thread 0887b9d4 callback
iscsid: thread 0x887b9d4 schedule: delay 0 state 3
iscsid: thread removed
----- s n i p -----
There is no iptables (everything is in ACCEPT):
----- s n i p -----
celia:~# iptables -L -n
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
celia:~# iptables -L -n -t nat
Chain PREROUTING (policy ACCEPT)
target prot opt source destination
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Chain POSTROUTING (policy ACCEPT)
target prot opt source destination
----- s n i p -----
Both the target(s), initiator(s) and iSNSd is running on the same
host and changing from iSNS to sendtarget does not change anything...
