Live Optics (Dell EMC) is an industry standard method of impartially documenting server/storage configuration and performance as well as observing file characteristics of data. 

This approach permits to analyse existing infrastructure and help decisions about upgrade or hardware renewal as well.

Very briefly:


  • It is a centralized backup management solution that enables you to create and manage backup tasks for all PCs, workstations, servers and virtual machines within LAN from a single central management computer.
  • Price are quite cheap.
  • You could remotely monitor backup jobs for all your clients with the central control server.
  • You could centrally manage and backup of all these clients to network share or NAS.

I did not have time to test it, and I hope to get a free trial licence to do that. Meanwhile I preferred taking note about that on blog and share this information, hoping that would be useful for someone.

Tips - Sitemap creation hosted BLOGGER web sites

Today I was working on google search console and I was surprised that only few pages was indexed, searching on internet I found problem resolution and applied some fixes.

Furthermore you may find more technical details and relative workflow.

<===========================>


  • Sitemap file functionality is used mentioning all website pages, unfortunately this is not true for websites hosted on blogger environments.


  • Default blogger XML file refers only to 26 most recent articles.


  • Consequential limitation is easy to be understood (for search engine websites visibility and indexing first)


  • You might override this limitation going to this website https://ctrlq.org/blogger/, indicate your website, get XML text and insert it in your blogger administration console ( Settings – > Search Preferences, the enable Custom robots.txt option (available in the Crawling and Indexing section).


In this way all search engines will discover your XML sitemap and indexing at all.

Here they are some screenshots 









Tips - How to get domain controller ldap string

If you need to find ldap string on Microsoft Domain Controller there are various and quickly way suitable for this purpose:

a.) dsquery

Consider that for help on a specific command, type "dsquery /?" where is one of the supported object types shown above.

For example, dsquery ou /?

Description: This tool's commands suite allow you to query the directory
according to specified criteria. Each of the following dsquery commands finds
objects of a specific object type, with the exception of dsquery *, which can
query for any type of object:

dsquery computer - finds computers in the directory.
dsquery contact - finds contacts in the directory.
dsquery subnet - finds subnets in the directory.
dsquery group - finds groups in the directory.
dsquery ou - finds organizational units in the directory.
dsquery site - finds sites in the directory.
dsquery server - finds AD DCs/LDS instances in the directory.
dsquery user - finds users in the directory.
dsquery quota - finds quota specifications in the directory.
dsquery partition - finds partitions in the directory.
dsquery * - finds any object in the directory by using a generic LDAP query.

For help on a specific command, type "dsquery /?" where
is one of the supported object types shown above.
For example, dsquery ou /?.

Remarks:
The dsquery commands help you find objects in the directory that match
a specified search criterion: the input to dsquery is a search criterion
and the output is a list of objects matching the search. To get the
properties of a specific object, use the dsget commands (dsget /?).

The results from a dsquery command can be piped as input to one of the other
directory service command-line tools, such as dsmod, dsget, dsrm or dsmove.

Commas that are not used as separators in distinguished names must be
escaped with the backslash ("\") character
(for example, "CN=Company\, Inc.,CN=Users,DC=microsoft,DC=com").

Backslashes used in distinguished names must be escaped with a backslash
(for example,
"CN=Sales\\ Latin America,OU=Distribution Lists,DC=microsoft,DC=com").


Examples:
To find all computers that have been inactive for the last four weeks and
remove them from the directory:

        dsquery computer -inactive 4 | dsrm

To find all users in the organizational unit
"ou=Marketing,dc=microsoft,dc=com" and add them to the Marketing Staff group:

        dsquery user ou=Marketing,dc=microsoft,dc=com | dsmod group
        "cn=Marketing Staff,ou=Marketing,dc=microsoft,dc=com" -addmbr

To find all users with names starting with "John" and display his office
number:

        dsquery user -name John* | dsget user -office

To display an arbitrary set of attributes of any given object in the
directory use the dsquery * command. For example, to display the
sAMAccountName, userPrincipalName and department attributes of the object
whose DN is ou=Test,dc=microsoft,dc=com:

        dsquery * ou=Test,dc=microsoft,dc=com -scope base
        -attr sAMAccountName userPrincipalName department

To read all attributes of the object whose DN is ou=Test,dc=microsoft,dc=com:

        dsquery * ou=Test,dc=microsoft,dc=com -scope base -attr *

Directory Service command-line tools help:
dsadd /? - help for adding objects.
dsget /? - help for displaying objects.
dsmod /? - help for modifying objects.
dsmove /? - help for moving objects.
dsquery /? - help for finding objects matching search criteria.
dsrm /? - help for deleting objects.

b.) Meanwhile you could find LDAP connection string launching ADSI Edit snapin:
