The well known files resolv.conf and nsswitch.conf are no longer important in Solaris 11. 
The new way to change DNS configuration is by using SMF: 

* Define new dns settings (resolv.conf)
svccfg -s dns/client "setprop config/nameserver = net_address: 10.0.1.1"
svccfg -s dns/client "setprop config/domain = astring: raghon.no"
svccfg -s dns/client "setprop config/search = astring: raghon.no"
svcadm enable dns/client

* Configure name-service switch (nsswitch.conf)

svccfg -s name-service/switch "setprop config/host = astring: \"files dns\""
svcadm restart name-service/switch

Install the iscsi services 
- pkg install group/feature/storage-server
- svcadm enable stmf

Backup current configuration
- svccfg export -a stmf >/var/tmp/COMSTAR
If needed restore configuration
- svccfg import /var/tmp/COMSTAR

Create a new lun
- zfs create -V 2g rpool/vol1
- stmfadm create-lu /dev/zvol/rdsk/rpool/vol1 
- stmfadm list-lu ; to get name of new lun id

Create a host group who are allowed to connect to the new lun (opional)
- stmfadm create-hg tx-nfs
Add members:
- stmfadm  add-hg-member -g tx-nfs iqn.1986-03.com.sun:node1
- stmfadm  add-hg-member -g tx-nfs iqn.1986-03.com.sun:node2

Create a view for the new lun, including access for the new host group
- stmfadm add-view -n 10 -h  tx-nfs 600144F0D2D88F0000004F3BF9E30001
        * -n 10 ; defines the lun number (optional)
        * -h tx-nfs ; defines the host group to allow access (optional)
        * -t ??? ; defines an optional target group
Enable iscsi target
- svcadm enable -r svc:/network/iscsi/target:default
Create iscsi targete
- itadm create-target  -n iqn.1986-03.com.sun:iscsi01 -l iscsi01   
     * -n ; an optional name for the iqn   
     * -l ; optional alias for the iqn


Test the new target using automatic discovery from the same or other server:
* Define a readable iqn name, and alias for the current server
    - iscsiadm modify initiator-node -A iscsi01 -N iqn.1986-03.com.sun:node1
* Enable static discovery 
   - iscsiadm modify discovery -s enable
* Add a static configuration for the new lun
   - iscsiadm add static-config iqn.1986-03.com.sun:iscsi01,10.0.1.51
* Look for new luns using devfsadm 
   - devfsadm -i iscsi

Verify the new lun:
- echo | format ; look for a lun named SUN-COMSTAR
- iscsiadm list target -S

Make a zfs pool on the new disk
* If the system is running on AMD/Intel (x86), fdisk the disk with a solaris partition
  - echo | format
      - identifiy the new disk; look for SUN-COMSTAR
  - fdisk -B c0t600144F0EA3E8C0000004F3BBA1C0001d0p0 # Add p0 to the end of the name
* Create the zpool
  - zpool create newpool c0t600144F0EA3E8C0000004F3BBA1C0001d0

As of Solaris 11, a lot of configuration files are obsolete. The config has moved to SMF. 

Enable static ip definition; disabling NWAM
- netadm enable -p ncp DefaultFixed
Change hostname: 
- svccfg -s node setprop config/nodename = "new_hostname"
- svccfg -s node setprop config/loopback = "new_hostname"
- svcadm refresh svc:/system/identity:node
- svcadm restart svc:/system/identity:node (svcadm restart node works as well)

Change IP: 
- identify current interface/ip   
- ipadm show-addr ; (ADDROBJ identifies the interface)
- delete current interface definition   
- ipadm delete-addr net0/v4 (net0/v4 is the ADDROBJ from ipadm show-addr)   
- ipadm create-ip net0 (if not already defined)

- ipadm create-addr -T static -a 10.0.1.52/24 net0/v4
- verify the new configuration   
- ipadm show-addr ; or ifconfig -a

Define default router
- route -p add default 10.0.1.1

I'v been playing a bit with OpenPGP, and lots of plugins for different applications. PGP is very good product, but it has one big drawback, its not supported out of the box. Looks like S/MIME is the standard. Now also supported with ios5 :-)

I discovered a very simple and easy guide to configure S/MIME on osx and iphone/ipad. 

I choose to create a free certificate  at http://www.instantssl.com/ssl-certificate-products/free-email-certificate.html. Others are available, like versign etc. 

My only problem was importing the key on my ios devices. This worked for me: 

1. Follow this guide http://arstechnica.com/apple/guides/2011/10/secure-your-e-mail-under-mac-os-x-and-ios-5-with-smime.ars?comments=1&start=40#comments-bar to add the certificate to osx

2. Open Keychain Access
3. Click "My Certificates" at bottom left
4. Expand your new certificate, and choose both entries
5. Rigth click, and export 2 items as .p12
6. Send the file as email, or transfer the file securly to you ios device
7. Open the file on ios
8. Enable S/MIME for email
9. Enable S/MIME
      - Open settings mail - account - account - advanced - S/MIME
      - Enable signing ; choose the new cert 
      - Enable crypt ; choose the new cert

You are now able to send and receive encrypted email from osx and ios.
