Hi Mike,
As we discussed last week, I have taken up TODO- userspace list item #2.
I have analysed and coded on some part of it on this weekend :-
For timeout and CHAP I have taken following parameters values from /sys and
printed it.
[root@a usr]# ls /sys/class/iscsi_session/session17/ | grep tmo
abort_tmo
lu_reset_tmo
recovery_tmo
The o/p looks like:-
[root@a usr]# ./iscsiadm -m session -P3
Target: iqn.2004-05.xyz.bumblee

If output looks ok then I will improve and forward the final patch, also let
me know if I have missed out something in timeout/CHAP.
For displaying CHAP :-
Shall I display password also in text form or print '*' instead.
(as on running iscsiadm -m node -T <target name> -p <ip>, it displays only.
I mean :-
[root@localhost ~]# iscsiadm -m node -T <target name> -p <ip>
# BEGIN RECORD 2.0-872
node.name = iqn.2004-05.com.xyz.bumblee2
node.tpgt = 1
node.startup = automatic
node.leading_login = No
iface.hwaddress = <empty>
iface.ipaddress = <empty>
.
.
node.session.auth.authmethod = CHAP
node.session.auth.username = initiator_id1
node.session.auth.password = ********
node.session.auth.username_in = target_id1
node.session.auth.password_in = ********
node.session.timeo.replacement_timeout = 120
.
.
)
These values needs to be printed in print level3 only or in 0/1/2.
Also, plz let me know if I have missed out any iscsi value that has to be
printed in above list.
Regards,
Rahul Gupta.
