ZFS Deduplication Property Solaris Express Community Edition,build 129: In this Solaris release,you can use the deduplication property to remove redundant data from your ZFS file systems. If a file system has the dedup property enabled,duplicate data blocks are removed synchronously. The result is that only unique data is stored and common components are shared between files.
You can enable this property as follows:
# zfs set dedup=on tank/home

A: You will see two files starting with id_rsa. id_rsa is the private key and id_rsa.pub is public key.
E: The .ssh/known_hosts file
In order to use public-key secure connection with other hosts (ssh,scp,sftp) there is a special directory,~/.ssh/,where passphrases and public keys are stored. Normally you wouldn't need to know the gory details,but from time to time a host will change its public key and then you have difficulty using ssh or scp with that host,and have to edit a file named known_hosts. If you try to ssh to another computer,but get an error message that warns about a changed or incorrect public key,then it is probably just a case of that host changing its public key. (It is possible,though usually not the case,that malicious hacking is involved.) Unless you actually suspect hacker involvement,you can edit the file ~/.ssh/known_hosts using your usual text editor (vi,emacs,nedit,or pico) and delete any line with the name of that host.
Then when you try to ssh that host again,it will be like the first time ever; ssh will ask you if you want to accept a new public key,you type the whole word yes,and everything will proceed normally from there.
Here is what a typical ~/.ssh/known_hosts file might contain. Note that newton is represented on two different lines:

Explanation/Reference:
Explanation:
A: Solaris uses a UID (User ID) to identify each user account. The UID is a unique number assigned to each user. It is usually assigned by the operating system when the account is created.
B: In Solaris the account name can include any alphanumeric string (and . _ -). The maximum length is 8 characters.
