How to quickly create a Solaris zone?

sh-3.00# zonecfg -z web1-zone
web1-zone: No such zone configured
Use 'create' to begin configuring a new zone.
zonecfg:web1-zone> create
zonecfg:web1-zone> set zonepath=/export/home/zones/web1-zones
zonecfg:web1-zone> set autoboot=true
zonecfg:web1-zone> add net
zonecfg:web1-zone:net> set address=10.1.70.233
zonecfg:web1-zone:net> set address=10.1.70.233/24
zonecfg:web1-zone:net> set physical=bge1
zonecfg:web1-zone:net> end
zonecfg:web1-zone> set pool=email-pool
zonecfg:web1-zone> verify

How to change a Solaris zone netmask?

So it's all in /etc/zones/.xml but they tell you not to touch it.

In here:
http://forums.sun.com/thread.jspa?threadID=5075758

They tell you to run this:

zonecfg -z email-zone
zonecfg:email-zone> remove net address=10.1.30.232
zonecfg:email-zone> add net
zonecfg:email-zone:net> set address=10.1.70.232/24
zonecfg:email-zone:net> set physical=bge0
zonecfg:email-zone:net> end
zonecfg:email-zone> commit
zonecfg:email-zone> exit

Use this format for new-ip to configure a specific subnet mask: 10.1.30.232/24.

Debugging security with sectrace

A new command called "sectrace" can help debug security problems (e.g. user cannot chown a file with NT ACL).

sectrace add -a -path /vol/software

will produce meesages such as these:

Sun Feb 1 13:10:52 IST [jim: sectrace.filter.allowed:info]: [sectrace index: 2] Access allowed because 'Synchronize, Read Attributes' permission (0x100080) is granted on file or directory (Access allowed by an explicit access control entry) - Status: 1:58720452:0:0 - 10.1.20.107 - NT user name: support\administrator - UNIX user name: root(0) - Qtree security style is NTFS and NT ACL is set on file/directory - Path: /vol/software/

Typically there is no need to use -a since you only want to debug DENY replies.

Migrate Data with Robocopy

robocopy C:\ \\\ /MIR /COPYALL /Z /LOG:C:\Robocopy.txt /R:0 /W:0 /NP /XD RECYCLER "System Volume Information" ~snapshot

Some explanations:

• /Z - Restartable Mode - If Robocopy is stopped, then restarted, partially copied files are picked up and incrementally copied.
• /B - Backup Mode - In some cases it is advised to also add the /B (Backup Mode) option to copy files in backup mode. This option leverages the Windows NT "backup mode" feature, allowing files to be copied using the Backup Operator rights.
