This post demonstrates how to enable bidirectional or mutual CHAP on iSCSI luns between Oracle Enterprise Linux 6 update 5 and NetApp storage. The aggregate, lun and disk sizes are small in this HOWTO to keep it simple.

1) Install open-iscsi on your server.
> yum install iscsi-initiator*
> reboot (don’t argue with me, just do it!)

2) Display your server’s new iscsi initiator or iqn nodename.
> cat /etc/iscsi/initiatorname.iscsi
InitiatorName=iqn.1988-12.com.oracle:523325af23

3) On the NetApp filer, create the volume that will hold the iscsi luns. This command assumes you have aggregate aggr1 already created. If not, use an aggregate that has enough room for your volume.
netapp> vol create MCHAPVOL aggr1 10g

4) Create the lun in the volume.
netapp> lun create -s 5g -t linux /vol/MCHAPVOL/OEL6u5_iSCSI_MCHAP_01

5) Create an igroup and add the Oracle Enterprise Linux iscsi nodename or iqn from step 2 above to it.
netapp> igroup create -i -t linux ISCSI_MCHAP_OEL6u5
netapp> igroup add ISCSI_MCHAP_OEL6u5 iqn.1988-12.com.oracle:523325af23
netapp> igroup show ISCSI_MCHAP_OEL6u5
ISCSI_MCHAP_OEL6u5 (iSCSI) (ostype: linux):
iqn.1988-12.com.oracle:523325af23 (not logged in)

6) Map the lun to the igroup and give it lun ID 01.
netapp> lun map /vol/MCHAPVOL/OEL6u5_iSCSI_MCHAP_01 ISCSI_MCHAP_OEL6u5 01

7) Obtain the NetApp target nodename.
netapp> iscsi nodename
iqn.1992-08.com.netapp:sn.84167939

8) Set the CHAP secret on the NetApp controller.
netapp> iscsi security add -i iqn.1988-12.com.oracle:523325af23 -s chap -p MCHAPOEL6u5 -n iqn.1988-12.com.oracle:523325af23 -o NETAPPMCHAP -m iqn.1992-08.com.netapp:sn.84167939

netapp> iscsi security show
init: iqn.1988-12.com.oracle:523325af23 auth: CHAP Inbound password: **** Inbound username: iqn.1988-12.com.oracle:523325af23 Outbound password: **** Outbound username: iqn.1992-08.com.netapp:sn.84167939

9) On the server, edit your /etc/iscsi/iscsi.conf file and set the parameters below.
> vi /etc/iscsi/iscsid.conf
node.startup = automatic
node.session.auth.authmethod = CHAP
node.session.auth.username = iqn.1988-12.com.oracle:523325af23
node.session.auth.password = MCHAPOEL6u5
node.session.auth.username_in = iqn.1992-08.com.netapp:sn.84167939
node.session.auth.password_in = NETAPPMCHAP
discovery.sendtargets.auth.authmethod = CHAP
discovery.sendtargets.auth.username = iqn.1988-12.com.oracle:523325af23
discovery.sendtargets.auth.password = MCHAPOEL6u5
discovery.sendtargets.auth.username_in = iqn.1992-08.com.netapp:sn.84167939
discovery.sendtargets.auth.password_in = NETAPPMCHAP
> wq!

10) On the server, restart the service and discover your iSCSI target (your storage system).
> service iscsi restart
> iscsiadm -m discovery -t st -p 10.10.10.11
10.10.10.11:3260,1000 iqn.1992-08.com.netapp:sn.84167939

> iscsiadm -m node (this should display the same as above)
10.10.10.11:3260,1000 iqn.1992-08.com.netapp:sn.84167939

11) On the server, manually login to the iSCSI target (your storage array). Note there are two dashes “- -” in front of –login. It always looks like one.
> iscsiadm -m node -T “iqn.1992-08.com.netapp:sn.84167939” –login
Logging in to [iface: default, target: iqn.1992-08.com.netapp:sn.84167939, portal: 10.10.10.11,3260] (multiple)
Login to [iface: default, target: iqn.1992-08.com.netapp:sn.84167939, portal: 10.10.10.11,3260] successful.

Verify the iSCSI session on the filer:
netapp> iscsi session show
Session 10
Initiator Information
Initiator Name: iqn.1988-12.com.oracle:523325af23
ISID: 00:02:3d:01:00:00
Initiator Alias: oel6u5

12) Stop and start the iscsi service on the server.
> service iscsi stop
Pause for 10 seconds and then run the next command.
> service iscsi start

13) From the server, check your session.
> iscsiadm -m session -P 1

19) Add the new mount point to /etc/fstab.
> vi /etc/fstab
/dev/sdb1 /newiscsilun ext4 _netdev 0 0
> wq!

Note: the _netdev option is important so that it doesn’t try mounting the target before the network is available.

20) Test that it survives a reboot by rebooting the server. With the _netdev set, iscsi starts and your CHAP logins should take place before it attempts to mount. After the reboot, login and verify its mounted.
> reboot

When done rebooting, login and verify the lun is mounted.

Oracle Enterprise Linux 6.5 Hangs after Starting Certmonger

Linux, Oracle

So, you are installing Oracle Enterprise Linux 6 update 5 and you select the Desktop group of packages. When the system is finished installing and finally boots, it hangs at certmonger. The certmonger daemon monitors certificates for impending expiration, and can optionally refresh soon to be expired certificates with the help of a CA.

Why this kills the Desktop if X isn’t installed is beyond me. For some reason the dependent packages don’t get selected by yum. To fix it, perform the following steps.

1) Reboot and press the spacebar key to enter the boot menu during system start-up.
a) When the Grub menu appears, press the ‘e’ key.
b) Scroll down to the line with kernel and press the ‘e’ again.
c) At the end of the line, the last word should be ‘quiet’. Right arrow key over to the end of the line and press spacebar once to add a space after the word ‘quiet’ and press the 3 key.
d) Then press the Enter key and then the letter ‘b’ to boot the system.

2) The systems will boot into text mode. Now, add the X Window System rpm’s.
> yum update
> yum groupinstall “X Window System”

3) Reboot the system and you should have a working desktop.
> shutdown -r now

This post demonstrates how to enable two-way or mutual CHAP on iSCSI luns between CentOS Linux 5.10 and NetApp storage. The aggregate, lun and disk sizes are small in this HOWTO to keep it simple.

1) Install open-iscsi on your server.
> yum install iscsi-initiator*
> reboot (don’t argue with me, just do it!)

2) Display your server’s new iscsi initiator or iqn nodename.
> cat /etc/iscsi/initiatorname.iscsi
InitiatorName=iqn.1994-05.com.redhat:01241a79a24

3) On the NetApp filer, create the volume that will hold the iscsi luns. This command assumes you have aggregate aggr1 already created. If not use an aggregate that has enough room for your volume.
netapp> vol create MCHAPVOL aggr1 10g

4) Create the lun in the volume.
netapp> lun create -s 5g -t linux /vol/MCHAPVOL/CENTSOS510_iSCSI_MCHAP_01

5) Create an igroup and add the Linux iscsi nodename or iqn from step 2 above to it.
netapp> igroup create -i -t linux ISCSI_MCHAP_CENTOS510
netapp> igroup add ISCSI_MCHAP_CENTOS510 iqn.1994-05.com.redhat:01241a79a24
netapp> igroup show ISCSI_MCHAP_CENTOS510

ISCSI_MCHAP_CENTOS510 (iSCSI) (ostype: linux):
iqn.1994-05.com.redhat:01241a79a24 (not logged in)

6) Map the lun to the igroup and give it lun ID 01.
netapp> lun map /vol/MCHAPVOL/CENTSOS510_iSCSI_MCHAP_01 ISCSI_MCHAP_CENTOS510 01

7) Obtain the NetApp target nodename.
netapp> iscsi nodename
iqn.1992-08.com.netapp:sn.84167939

8) Set the CHAP secret on the NetApp controller.
netapp> iscsi security add -i iqn.1994-05.com.redhat:01241a79a24 -s chap -p MCHAPCENT510 -n iqn.1994-05.com.redhat:01241a79a24 -o NETAPPMCHAP -m iqn.1992-08.com.netapp:sn.84167939

netapp> iscsi security show
init: iqn.1994-05.com.redhat:01241a79a24 auth: CHAP Inbound password: **** Inbound username: iqn.1994-05.com.redhat:01241a79a24 Outbound password: **** Outbound username: iqn.1992-08.com.netapp:sn.84167939

9) On the server, edit your /etc/iscsi/iscsi.conf file and set the parameters below.
> vi /etc/iscsi/iscsid.conf:
node.startup = automatic
node.session.auth.authmethod = CHAP
node.session.auth.username = iqn.1994-05.com.redhat:01241a79a24
node.session.auth.password = MCHAPCENT510
node.session.auth.username_in = iqn.1992-08.com.netapp:sn.84167939
node.session.auth.password_in = NETAPPMCHAP
discovery.sendtargets.auth.authmethod = CHAP
discovery.sendtargets.auth.username = iqn.1994-05.com.redhat:01241a79a24
discovery.sendtargets.auth.password = MCHAPCENT510
discovery.sendtargets.auth.username_in = iqn.1992-08.com.netapp:sn.84167939
discovery.sendtargets.auth.password_in = NETAPPMCHAP
> wq!

> iscsiadm -m node (this should display the same as above)
10.10.10.11:3260,1000 iqn.1992-08.com.netapp:sn.84167939

11) On the server, manually login to the iSCSI target (your storage array). Note there are two dashes “- -” in front of targetname and login.
> iscsiadm -m node –targetname “iqn.1992-08.com.netapp:sn.84167939” –login

Logging in to [iface: default, target: iqn.1992-08.com.netapp:sn.84167939, portal: 10.10.10.11,3260] (multiple)
Login to [iface: default, target: iqn.1992-08.com.netapp:sn.84167939, portal: 10.10.10.11,3260] successful.

On the NetApp storage console you should see the iSCSI sessions:
Sun Nov 17 07:51:00 EST [iscsi.notice:notice]: ISCSI: New session from initiator iqn.1994-05.com.redhat:01241a79a24 at IP addr 10.10.10.37
Sun Nov 17 07:56:38 EST [iscsi.notice:notice]: ISCSI: New session from initiator iqn.1994-05.com.redhat:01241a79a24 at IP addr 10.10.10.37

Verify the iSCSI session on the filer:
netapp> iscsi session show

12) Stop and start the iscsi service on the server.
> service iscsi stop
Pause for 10 seconds and then run the next command.
> service iscsi start

13) From the server , check your session.
> iscsiadm -m session -P 1

iSCSI, Linux, NetApp, Security

This post demonstrates how to enable two-way or mutual CHAP on iSCSI luns between Debian Linux 7.1 and NetApp storage. The aggregate, lun and disk sizes are small in this HOWTO to keep it simple.

1) Install open-iscsi on your server.
> apt-get install open-iscsi
> reboot (don’t argue with me, just do it!)

2) Display your server’s new iscsi initiator or iqn nodename.
> cat /etc/iscsi/initiatorname.iscsi
InitiatorName=iqn.1993-08.org.debian:01:e6d4ee61d916

3) On the NetApp filer, create the volume that will hold the iscsi luns. This command assumes you have aggregrate aggr1 already created. If not use an aggregate that has enough room for your volume.
netapp> vol create MCHAPVOL aggr1 10g

4) Create the lun in the volume.
netapp> lun create -s 5g -t linux /vol/MCHAPVOL/DEB71_iSCSI_MCHAP_01

5) Create an igroup and add the Linux iscsi nodename or iqn from step 2 above to it.
netapp> igroup create -i -t linux ISCSI_MCHAP_DEB71
netapp> igroup add ISCSI_MCHAP_DEB71 iqn.1993-08.org.debian:01:e6d4ee61d916
netapp> igroup show

ISCSI_MCHAP_DEB71 (iSCSI) (ostype: linux):
iqn.1993-08.org.debian:01:e6d4ee61d916 (not logged in)

6) Map the lun to the iscsi-group and give it lun ID 01.
netapp> lun map /vol/MCHAPVOL/DEB71_iSCSI_MCHAP_01 ISCSI_MCHAP_DEB71 01

7) Obtain the NetApp target nodename.
netapp> iscsi nodename
iqn.1992-08.com.netapp:sn.84167939

8) Set the CHAP secret on the NetApp controller.
netapp> iscsi security add -i iqn.1993-08.org.debian:01:e6d4ee61d916 -s chap -p MCHAPDEB71 -n iqn.1993-08.org.debian:01:e6d4ee61d916 -o NETAPPMCHAP -m iqn.1992-08.com.netapp:sn.84167939

netapp> iscsi security show

init: iqn.1993-08.org.debian:01:e6d4ee61d916 auth: CHAP Inbound password: **** Inbound username: iqn.1993-08.org.debian:01:e6d4ee61d916 Outbound password: **** Outbound username: iqn.1992-08.com.netapp:sn.84167939

9) On the server, edit your /etc/iscsi/iscsi.conf file and set the parameters below.
> vi /etc/iscsi/iscsid.conf:
node.startup = automatic
node.session.auth.authmethod = CHAP
node.session.auth.username = iqn.1993-08.org.debian:01:e6d4ee61d916
node.session.auth.password = MCHAPDEB71
node.session.auth.username_in = iqn.1992-08.com.netapp:sn.84167939
node.session.auth.password_in = NETAPPMCHAP
discovery.sendtargets.auth.authmethod = CHAP
discovery.sendtargets.auth.username = iqn.1993-08.org.debian:01:e6d4ee61d916
discovery.sendtargets.auth.password = MCHAPDEB71
discovery.sendtargets.auth.username_in = iqn.1992-08.com.netapp:sn.84167939
discovery.sendtargets.auth.password_in = NETAPPMCHAP
> wq!

10) On the server, discover your iSCSI target (your storage system).
> iscsiadm -m discovery -t st -p 10.10.10.11
10.10.10.11:3260,1000 iqn.1992-08.com.netapp:sn.84167939

> iscsiadm -m node (this should display the same as above)
10.10.10.11:3260,1000 iqn.1992-08.com.netapp:sn.84167939

11) On the server, manually login to the iSCSI target (your storage array).
> iscsiadm -m node –targetname “iqn.1992-08.com.netapp:sn.84167939” –login

On the NetApp storage console you should see the iSCSI sessions:
[iscsi.notice:notice]: ISCSI: New session from initiator iqn.1993-08.org.debian:01:e6d4ee61d916 at IP addr 10.10.10.203
[iscsi.notice:notice]: ISCSI: New session from initiator iqn.1993-08.org.debian:01:e6d4ee61d916 at IP addr 10.10.10.203

Verify the iSCSI session on the filer:
netapp> iscsi session show
Session 49
Initiator Information
Initiator Name: iqn.1993-08.org.debian:01:e6d4ee61d916
ISID: 00:02:3d:01:00:00
Initiator Alias: deb71

12) Stop and start the iscsi service on the server.
> service open-iscsi stop
Pause for 10 seconds and then run the next command.
> service open-iscsi start

[ ok ] Starting iSCSI initiator service: iscsid.
[….] Setting up iSCSI targets:

13) From the server , check your session.
> iscsiadm -m session -P 1

14) From the server, check the NetApp iSCSI details.
> iscsiadm –mode node –targetname “iqn.1992-08.com.netapp:sn.84167939” –portal 10.10.10.11:3260

15) From the server, find and format the new lun (new disk).
> cat /var/log/messages | grep “unknown partition table”

At some point you will be asked by a Storage Engineer for your system’s iSCSI Initiator Node Name or your iqn. This list shows you how to get your local iSCSI initiator name or iqn from the command line. This assumes the iSCSI service is installed, enabled and running. If you have a different way or want to add an OS or platform to this list simply leave a comment and I’ll add it.

Tweaking the HP ArcSight Logger CentOS VMware Appliance

05 Wednesday Jun 2013

HP, Linux

So, HP ArcSight Logger is a CentOS 6.2 VMWare appliance. If you want to kick the tires, patch it and add a GUI desktop, perform the following steps.

– Note that this probably voids your support and is totally unsupported by HP.

1) Download the VM appliance from the URL below. I selected the VMware appliance. Extract the zip file and import the OVA into vCenter.

Click Trials and Demos here:
http://www8.hp.com/us/en/software-solutions/software.html?compURI=1314386

2) The The default root password is arcsight. They have configured ssh to allow remote root logins which is odd for a Security related product.

-> ssh root@<your logger vm IP>

3) Add the CentOS repository to yum.conf.

-> vi /etc/yum.conf and add the section below to the bottom of the file.

[base]
name=CentOS-$releasever – Base
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos6
enabled=1
#released updates

-> wq!

4) Import the key.

-> rpm –import http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6

4) Update yum.

-> yum update (enter no to update all packages)

5) Install the Desktop.

For a Gnome desktop run:
-> yum groupinstall Desktop

For a KDE desktop run:
-> yum groupinstall “kde desktop”

When done installing, fix a bug and add a few rpms.

-> mkdir -p /var/run/dbus/system_bus_socket;chmod 775 /var/run/dbus/system_bus_socket

-> yum install perl

-> yum install gpm

-> -yum install xorg-x11-drv-intel

6) Install VMware tools. Copy the vmware tools for linux iso file over to the vm via scp or Winscp, place in /tmp and mount.

-> mount -o loop VMware-tools-linux-9.0.5-1065307.iso /mnt

-> cd /mnt

-> cp VMwareTools-9.0.5-1065307.tar.gz /tmp/

-> cd /tmp/

-> umount /mnt

-> tar -zxvf VMwareTools-9.0.5-1065307.tar.gz

-> cd vmware-tools-distrib

-> ./vmware-install.pl (and follow the prompts – defaults are fine for now)

-> reboot

7) Increase the size of /boot so the patches can be applied. Download the systemrescuecd ISO, attach to the VM and boot into it. Note that you may have to boot into the VM bios and change the boot order by moving the CDROM device to the top.
a) once the ISO boots, at the prompt enter: startx.

Installing Nessus on Kali Linux

1) First step is patch your Kali Linux system.
> su – root
> apt-get update
> apt-get upgrade

2) For some crazy reason Nessus is not part of the default Kali tool set. There must be some drama between these guys. The kali apt-get repositories don’t have nessus so you must download the deb package from Tenable.

Choose the debian 6 x64 package here:
http://www.tenable.com/products/nessus/select-your-operating-system

3) Install nessus.
> su – root
> cd /to/path/of/nessus/download
> dpkg -i Nessus*.deb
> rm Nessus*.deb

4) Register nessus. Obtain the key from the email sent by Tenable when you registered. It will be used to register your home feed and authorize your instance to download plug-ins.
> cd /opt/nessus/bin/
> ./nessus-fetch –register “1234-ABCD-5678-EFGH-9101”
Note: there are two dashes “–” in front of –register
> cd /opt/nessus/etc/nessus
> cp nessusd.conf.imported nessusd.conf

5) Start nessus.

> /etc/init.d/nessusd start

6) Nessus takes about 10 minutes to initialize the first time. Launch a browser and enter https://localhost:8834 to see if its ready. When ready the wizard will start. Create a user, enter the word offline for the registration (since you already did this above) and then login.

Using Virtual Ethernet Adapters in Promiscuous Mode on Linux

VMware does not allow the virtual Ethernet adapter to go into promiscuous mode unless the user has permission to make that setting change. This follows the standard Linux practice that only root can put a network interface into promiscuous mode. See this VMware KB for details.
