Server - SMB Protocols some useful information



Consider that on each Win O.S. there are two services (one is necessary to connect to remote shares, other one is necessary to publish shares):
  1. Client (LanmanWorkstation)
    Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanWorkstation
  2. Server side (LanmanServer
    Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer

Here they are some useful commands:

Get-Service Lanman*
Get-SmbShare
Get-Service LanmanServer -DependentServices

To log any if SMB 1.0 protocol is enabled on file server you must use below powershell command 

Set-SmbServerConfiguration -AuditSmb1Access $True -Force

On eventviewer logs are here located:

Applications and Services Logs > Microsoft > Windows > SMBServer > Audit

EventID 3000 

to view events using powershell you must use:

Get-WinEvent -LogName Microsoft-Windows-SMBServer/Audit | Out-GridView

to view if SMB 1.0 is enabled 

Get-SmbServerConfiguration | select EnableSMB1Protocol

If you want to see which SMB versions are using your clients

Get-SmbSession | select ClientComputerName, ClientUserName, NumOpens, Dialect

Dialect is correct column indicating SMB version

There are possibilities to encrypt End-to-End encryption, for single share:

Set-SmbShare -Name Projects$ -EncryptData $True -Force

and for entirely file server

Set-SmbServerConfiguration –EncryptData $True -Force

Meanwhile Microsoft is going to not support, SMB 1 on Windows 11 due to well known security problems. (driver and DLL would not be included)

University - 24/04/2002 -24/04/2022 #personal special anniversary date

I have always found several difficulties publishing, on internet, or on social media, personal information and photos (if not in pediatric quantities).

But, today an exception is necessary, in fact, exactly 20 years ago, I got IT Engineer bachelor degree (five-year).

I finished high school having several difficulties and, the admission judgment ( exam state), was deserved (in negative sense). Among other things, my inclusion (Work world ) was strongly suggested.

I was really problematic (during high school time period)

I finished high school, using tooth and nails, due to fact I had presentiment that University was my way/destiny (the doubt was which one)

The computer science professor was decisive in choosing the university who, in addition to being a father's friend, welcomed us, into his office, telling us about engineer and his University experience.

After this meeting my, university roadmap, was clear in front of me.

Many thanks to IT professor, my parents who supported me financially (and in particular my father who, even he did not speak so much, always trusted in me), several sacrifices that I made (even more necessary, more than other students, due to the fact that I had studied almost nothing on high school) and, why not, a bit of luck (which, in life, it is always useful).

Due to reasons, indicated at the beginning, I do not publish degree day photos but, I like to mention, what "the great" Mathematical Analysis's professor Massimo Furi usually said:

"... There are no differences between a freshman who enters the university and an engineer, the freshman does not know anything for obvious reasons. Those who have just graduated no longer remember anything about what they have studied. But graduated persons has changed their mind/"formas mentis" ... "

and, I feel to add: graduated guys has, surely, two more gears (like mental plasticity)

I end up saying "IT Engineer Bachelor Degree was one, of the 'Missions impossible', that I successfully achieved"

.... latter things, here it is, friends of mine endorsement with whom we studied various exams... He mentioned, some aspects, that rarely are noticed by almost persons.


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

Trovo, da sempre, grande difficolta' nel pubblicare su internet, o sui social, informazioni e foto personali (se non in quantita' pediatrica).

In questa giornata e' doveroso fare una, piccola, eccezione.

Oggi, vent'anni fa esatti, mi laureavo:

Terminai le superiori con grossa difficolta', ed il giudizio di ammissione all'esame di stato (APPENDICE --> GIUDIZIO AMMISSIONE ESAME SUPERIORI), era meritato (in senso negativo). Tra l'altro si caldeggiava il mio inserimento nel mondo del lavoro (APPENDICE --> ESITO ESAMI SUPERIORI)

Ero, effettivamente, molto problematico (durante il periodo delle superiori)

Terminai le superiori, con le unghie e con i denti, perche' dentro me avevo il presentimento che la mia strada era di fare l'universita' (il dubbio era su quale)

Fu determinante, nella scelta dell'ateneo, l'allora professore d'informatica che, oltre ad essere amico di mio padre, ci accolse, nel suo ufficio per raccontarci di Ingegneria e della sua esperienza (essendo lui Ingegnere).

Dopo questo incontro ne rimasi folgorato ed ero oramai certo di quello che avrei voluto fare da grande.

Devo ringraziare tantissimo il professore di Informatica, i miei genitori che mi hanno sostenuto economicamente (ed in particolare mio padre che, anche se era di poche parole, ha sempre creduto in me), i tantissimi sacrifici da me fatti (ancor piu' necessari, piu' di altri studenti, per il fatto che avevo, alle superiori, studiato quasi niente) e, perche' no, un pizzico di fortuna (che nella vita serve sempre).

Non metto foto della laurea per i motivi indicati all'inizio ma indico quello che disse il "grande" professore di Analisi Matematica I e II Massimo Furi:

"...Non vi e' differenza tra una matricola che entra all'universita' e un ingegnere, la matricola non sa nulla per ovvi motivi. Chi si e' appena laureato non ricorda piu' niente di quello che ha studiato. Ma la persona laureata ha cambiato "formas mentis" ..."

ed aggiungo, ha due marce in piu' (come plasticita' mentale)

Finisco dicendo "IT Engineer Bachelor Degree was one, of the 'Missions impossibles', that I successfully achieved"

....dimenticavo, aggiungo l'endorsement di un mio amico con il quale abbiamo fatto vari esami insieme e, se non ricordo male, ci siamo laureati a pochi mesi di distanza... Ha centrato aspetti che ai piu' sfuggono, o sono sfuggiti, sul mio conto...
