From our work conversations to the most important documents of a project, everything is digitalized, stored and, many times, shared without us really knowing what happens to that information. Who has control over our data?\r\n\r\nIf we stop to think about it, all our information and that of many companies is in services managed by third parties that are not under our direct control. Therefore, we do not know what happens to that information, nor where in the world it is stored or of course who has access to it.\r\n\r\nThat is why many companies are concerned and look for secure alternatives that do not compromise their data or generate technological dependencies and Zextras Carbonio is a good alternative.\r\n\r\n<strong>What can you do with Zextras Carbonio Community Edition?<\/strong>\r\n\r\nThe answer is simple: practically everything you need to work and collaborate.\r\n<ul>\r\n \t<li><strong>Professional email:<\/strong> Manage your communications efficiently with a modern and adaptable tool.<\/li>\r\n \t<li><strong>Secure chat and video calls:<\/strong>Forget about depending on platforms that don&#8217;t guarantee privacy.<\/li>\r\n \t<li><strong>Collaboration on documents:<\/strong> Work with your team in real time, without sacrificing control of your files.<\/li>\r\n \t<li><strong>Centralized storage:<\/strong> Keep all your files in a safe place, accessible only to people you authorize.<\/li>\r\n<\/ul>\r\n<div><\/div>\r\nAnd all this in an environment that you can configure yourself, which must meet certain hardware requirements, 4 vCPUs, 16GB RAM and 50GB of disk space just for the system and Carbonio. You will have to assign more depending on your forecasts, that is, if you have, for example, 20 users and you want to give each one 10GB of mail, you will need 200GB.\r\n\r\nIn addition, Carbonio has 12 different roles that can be installed on a single node or on several to optimize and obtain high availability, so the requirements would be different. The minimum for a single node with everything is what was mentioned above.\r\n\r\n<strong>Ports required by Zextras Carbonio externally<\/strong>\r\n<p style=\"padding-left: 40px;\"><strong>Rol MTA (Mail Transfer Agent):<\/strong><\/p>\r\n\r\n<ul>\r\n \t<li style=\"list-style-type: none;\">\r\n<ul>\r\n \t<li><strong>25\/TCP (SMTP):<\/strong> Receiving incoming emails between servers.<\/li>\r\n \t<li><strong>465\/TCP (SMTP sobre TLS):<\/strong> Sending emails with TLS.<\/li>\r\n \t<li><strong>587\/TCP (SMTP autenticado):<\/strong> Sending authenticated emails requires STARTTLS.<\/li>\r\n<\/ul>\r\n<\/li>\r\n<\/ul>\r\n<div><\/div>\r\n<p style=\"padding-left: 40px;\"><strong>Rol Proxy:<\/strong><\/p>\r\n\r\n<ul>\r\n \t<li style=\"list-style-type: none;\">\r\n<ul>\r\n \t<li><strong>80\/TCP (HTTP):<\/strong> Unsecured connection to Carbonio web client, redirected to https.<\/li>\r\n \t<li><strong>110\/TCP (POP3):<\/strong> External POP3 services.<\/li>\r\n \t<li><strong>143\/TCP (IMAP):<\/strong> External IMAP services.<\/li>\r\n \t<li><strong>443\/TCP (HTTPS):<\/strong> Secure connection to the Carbonio web client.<\/li>\r\n \t<li><strong>993\/TCP (IMAPS):<\/strong> External secure IMAP access.<\/li>\r\n \t<li><strong>995\/TCP (POP3S):<\/strong> External secure POP3 access.<\/li>\r\n \t<li><strong>5222\/TCP (XMPP):<\/strong> Required by the Work Stream Collaboration (Chat) role.<\/li>\r\n \t<li><strong>6071\/TCP (HTTPS):<\/strong> Secure access to the Administration Panel.<\/li>\r\n<\/ul>\r\n<\/li>\r\n<\/ul>\r\n<div><\/div>\r\n<p style=\"padding-left: 40px;\"><strong>Rol Carbonio VideoServer:<\/strong><\/p>\r\n\r\n<ul>\r\n \t<li style=\"list-style-type: none;\">\r\n<ul>\r\n \t<li><strong>20000-40000\/UDP:<\/strong> Client connections for audio and video transmissions.<\/li>\r\n<\/ul>\r\n<\/li>\r\n<\/ul>\r\n<div><\/div>\r\n<strong>Ports required by Zextras Carbonio internally<\/strong>\r\n<p style=\"padding-left: 40px;\"><strong>En cada Nodo:<\/strong><\/p>\r\n\r\n<ul>\r\n \t<li style=\"list-style-type: none;\">\r\n<ul>\r\n \t<li><strong>22\/TCP (SSH):<\/strong> SSH access for administration.<\/li>\r\n \t<li><strong>8301\/TCP y UDP:<\/strong> Managing the Gossip protocol on the LAN.<\/li>\r\n \t<li><strong>9100\/TCP:<\/strong> Data exporter for Carbonio Monitoring Node.<\/li>\r\n \t<li><strong>9256\/TCP:<\/strong> Process exporter for Carbonio Monitoring.<\/li>\r\n<\/ul>\r\n<\/li>\r\n<\/ul>\r\n<div><\/div>\r\n<p style=\"padding-left: 40px;\"><strong>Rol Postgres:<\/strong><\/p>\r\n\r\n<ul>\r\n \t<li style=\"list-style-type: none;\">\r\n<ul>\r\n \t<li><strong>5432\/TCP:<\/strong> Access to the Postgres database.<\/li>\r\n \t<li><strong>9187\/TCP:<\/strong> Exporting data from Postgres for Carbonio Monitoring.<\/li>\r\n<\/ul>\r\n<\/li>\r\n<\/ul>\r\n<div><\/div>\r\n<p style=\"padding-left: 40px;\"><strong>Rol Directory Server:<\/strong><\/p>\r\n\r\n<ul>\r\n \t<li style=\"list-style-type: none;\">\r\n<ul>\r\n \t<li><strong>389\/TCP:<\/strong> Insecure LDAP connection.<\/li>\r\n \t<li><strong>636\/TCP:<\/strong> Secure LDAP connection.<\/li>\r\n \t<li><strong>9330\/TCP:<\/strong> Exporting LDAP data for Carbonio Monitoring.<\/li>\r\n<\/ul>\r\n<\/li>\r\n<\/ul>\r\n<div><\/div>\r\n<p style=\"padding-left: 40px;\"><strong>Rol MTA:<\/strong><\/p>\r\n\r\n<ul>\r\n \t<li style=\"list-style-type: none;\">\r\n<ul>\r\n \t<li><strong>25\/TCP (SMTP):<\/strong> Receiving incoming emails.<\/li>\r\n \t<li><strong>465\/TCP (SMTP sobre TLS):<\/strong> Sending emails with TLS.<\/li>\r\n \t<li><strong>587\/TCP (SMTP autenticado):<\/strong> Sending authenticated emails requires STARTTLS.<\/li>\r\n \t<li><strong>7026\/TCP:<\/strong> Milter service link address.<\/li>\r\n<\/ul>\r\n<\/li>\r\n<\/ul>\r\n<div><\/div>\r\n<p style=\"padding-left: 40px;\"><strong>Rol Mailstore &amp;

We will need at least one public IP associated with an A record such as mail.domain.com and an MX record that corresponds to the A record, for example domain.com. We must also implement SPF, DKIM and DMARC records to improve security. It is also necessary that there are no IPv6 entries in our hosts files.\r\n\r\nIf we are going to install several servers with several nodes, we must have a clear architecture from the start to name these nodes and make our lives easier in the future, for example:\r\n<p style=\"padding-left: 40px;\"><strong>proxy1.domain.com<\/strong> is the (first) proxy node<\/p>\r\n<p style=\"padding-left: 40px;\"><strong>mta1.domain.com<\/strong> is the (first) MTA node<\/p>\r\nIf we expand these roles the following would be:\r\n<p style=\"padding-left: 40px;\"><strong>proxy2.domain.com<\/strong> becomes the second proxy node<\/p>\r\n<p style=\"padding-left: 40px;\"><strong>mta2.domain.com<\/strong> becomes the second MTA node<\/p>\r\nAll of this may seem very complex, but it is not, since once you understand the roles and the manual installation process, it is simple and well documented. You can easily start testing the system with everything on a single node by installing it using the script provided by Zextras.\r\n\r\nTo do this, you only need Ubuntu 22.04 and run these commands to add the Carbonio repositories.\r\n<p style=\"padding-left: 40px;\">sh -c &#8216;echo &#8220;deb [arch=amd64 signed-by=\/usr\/share\/keyrings\/zextras.gpg] https:\/\/repo.zextras.io\/release\/ubuntu jammy main&#8221; &gt; \/etc\/apt\/sources.list.d\/zextras.list&#8217;<\/p>\r\n<p style=\"padding-left: 40px;\">wget -O- &#8220;https:\/\/keyserver.ubuntu.com\/pks\/lookup?op=get&amp;search=0x5dc7680bc4378c471a7fa80f52fd40243e584a21&#8221; \\\r\n| gpg &#8211;dearmor | sudo tee \\\r\n\/usr\/share\/keyrings\/zextras.gpg &gt; \/dev\/null<\/p>\r\n<p style=\"padding-left: 40px;\">chmod 644 \/usr\/share\/keyrings\/zextras.gpg<\/p>\r\n<p style=\"padding-left: 40px;\">sh -c &#8216;echo &#8220;deb https:\/\/apt.postgresql.org\/pub\/repos\/apt $(lsb_release -cs)-pgdg main&#8221; &gt; \/etc\/apt\/sources.list.d\/pgdg.list&#8217;<\/p>\r\n<p style=\"padding-left: 40px;\">wget -O- &#8220;https:\/\/www.postgresql.org\/media\/keys\/ACCC4CF8.asc&#8221; | \\\r\ngpg &#8211;dearmor | sudo tee \/usr\/share\/keyrings\/postgres.gpg &gt; \\\r\n\/dev\/null<\/p>\r\n<p style=\"padding-left: 40px;\">chmod 644 \/usr\/share\/keyrings\/postgres.gpg\r\nsed -i &#8216;s\/deb\/deb [signed-by=\\\/usr\\\/share\\\/keyrings\\\/postgres.gpg] \/&#8217; \/etc\/apt\/sources.list.d\/pgdg.list<\/p>\r\n<p style=\"padding-left: 40px;\">apt-get update<\/p>\r\nOnce we have the repositories, we download the script that you can obtain by visiting their website at<strong><a href=\"https:\/\/zextras.com\/es\/carbonio-community-edition\" target=\"_blank\" rel=\"noopener\">\u00a0Zextras Carbonio Community Edition<\/a><\/strong>\r\n\r\nIt is <strong>very important<\/strong> that before launching the script our hostname and hosts file have the full name with the domain, otherwise we will receive the error &#8220;service-discover: error: invalid binding address selected&#8221;, also producing the following errors service-discover: error: unable to open \/etc\/zextras\/service-discover\/cluster-credentials.tar.gpg.
