Sicurezza / abilitare TLS 1.2 su centOS

« il: 13 Maggio 2017, 12:49:35 »

Salve a tutti
dovrei iniziare ad utilizzare il sistema di pagamento online di Stripe che ha commissioni migliori rispetto a paypal.

Il problema è che sembra che sul mio server sia attivo il TLS 1.0 e non 1.2 che è uno dei requisiti per poter utilizzare quel sistema.

Volevo sapere se sapete darmi informazioni su come fare questo aggiornamento e se nel farlo potrei causare dei problemi e non far funzionare niente piu'.

Qualcuno potrebbe illuminarmi?
Grazie

Supporto Generale / ERROR 1045 (28000): Access denied for user... come risolvo?

« il: 14 Febbraio 2016, 00:37:54 »

Salve a tutti e buon week end.

Ho preso un server dedicato da una nota azienda italiana sul quale hanno installato plesk ed i vari componenti web come apache, mysql, php ecc.
In pratica e' un server bello e pronto per far funzionare i propri siti web.

Su questo server sto cercando di installare un centralino con asterisk e sto seguendo questa guida:
http://wiki.freepbx.org/display/FOP/Installing+FreePBX+12+on+CentOS+6.5
Premetto che tale guida l'ho già seguita per installare un centralino su un server cloud con successo.

Ora mi ritrovo nella parte della guida dove dicono: "Configure Asterisk database in MYSQL"
I primi 2 comandi sono andati bene ma quando lancio il comando "mysqladmin -u root create asterisk" ricevo questo errore:
error: 'Access denied for user 'root'@'localhost' (using password: NO)'

Sapete cosa vuol dire e come posso risolvere?
Sono 2 giorni che sto fermo in questo punto...

Spero possiate aiutarmi
Grazie

Server / Problema di spam che invia il mio server (non sono io)

« il: 30 Luglio 2015, 23:14:59 »

Ciao a tutti
ho un server centos dove ho alcuni siti installati, tutti di mia proprietà

Il gestore mi invia da qualche giorno segnalazioni che il mio server invia email di spam, l'altro giorno in coda ce ne stavano tipo 400 mila...

Non so chi possa essere e come mai accade cio'.

Esiste un modo, con plesk, per dire che quel server deve inviare massimo tot (esempio) 10 email contemporaneamente?

Come potrei scoprire se e' presente un file che invia email dal mio server (magari qualcuno e' entrato e l'ha installato)?

Spero che qualcuno possa darmi una mano.
Grazie

Server / aggiornare php alla versione 5.3.10 è possibile, se si, come?

« il: 21 Maggio 2014, 21:48:11 »

ciao a tutti
avrei urgente bisogno di aggiornare la versione del mio php dalla 5.3.3 alla 5.3.10

Sapete dirmi come posso fare da shell o tramite plesk e se potrebbe compromettere i siti attualmente online?
Grazie

Server / postfix, problemi su invio delle email: dns, helo, spf

« il: 29 Aprile 2014, 17:38:58 »

ciao a tutti
sono un paio di giorni che non riesco ad inviare le email a destinatari tipo gmail o hotmail

quelli che mi forniscono il server mi hanno detto di seguire questi passi

1. The SMTP banner/helo is set to a non-generic hostname
2. The reverse DNS is set and matches the SMTP banner/HELO
3. SPF and DKIM records are set.

Potete dirmi passo passo come poter configurare al meglio questo server?
Utilizzo plesk ma all'evenienza posso metterci mano anche da shell (preferisco plesk se posso fare tutto da la')

Grazie

« il: 03 Febbraio 2013, 21:51:47 »

ho preso un server con una licenza di plesk con 10 domini e volevo chiedere se potevo usare webmin per i restanti domini che ho.
Sapete nulla a riguardo?
Grazie!

Server / Evitare lo spam

« il: 28 Ottobre 2011, 14:38:32 »

Ciao a tutti, sono nuovo.

Ho un server dedicato da aruba e su abbiamo montato plesk.
Pago una cifra di 2.40 euro a mese mi sembre per il servizio antispam (spamassasin) ma non riesco proprio a non ricevere email di spam

Ogni giorno su tutti i miei account di posta @miodominio.it ricevo circa 100 email

Come posso fare a ricevere solo le email buone?

Abbiamo spamassasin ma o non l'abbiamo impostato bene oppure non fa il suo lavoro.
Sapete aiutarmi, sono disperato
