Auto install NFS services script for Proxmox Server

Auto install NFS services script for Proxmox Server

What is NFS?
Services for Network File System (NFS) provides a file-sharing solution for enterprises that have a mixed Windows and UNIX environment. Services for NFS enables users to transfer files between computers running the Windows Server operating system and UNIX-based computers using the NFS protocol.

The below script will auto install & configure NFS in your linux server with “*” wildcard access of “/home/nfs” folder location, will adjust everything you need including your firewall and auto boot for NFS.

This script will also re-config your proxmox server storage model reverting the “Thin-LVM” to old behavior of “/var/lib/vz” partition so that NFS will use the full storage of your Proxmox Server (details: https://pve.proxmox.com/wiki/Installation:_Tips_and_Tricks ) of this mod.

before running script make sure that your Proxmox 4.2+ has an fresh copy and you have “wget” installed “apt-get install wget -y”. NocRoom holds no responsibly and use at your own risk.

wget dl.nocroom.com/files/nfs-proxmox.sh
chmod 777 ./nfs.sh
./nfs.sh

Most common exports options

Here are the most common NFS export techniques and options:

/home/nfs/ 10.1.1.55(rw,sync) export /home/nfs directory for host with an IP address 10.1.1.55 with read, write permissions, and synchronized mode
/home/nfs/ 10.1.1.0/24(ro,sync) export /home/nfs directory for network 10.1.1.0 with netmask 255.255.255.0 with read only permissions and synchronized mode
/home/nfs/ 10.1.1.55(rw,sync) 10.1.1.10(ro,sync) export /home/nfs directory for host with IP 10.1.1.55with read, write permissions, synchronized mode, and also export /home/nfs directory for another host with an IP address 10.1.1.10 with read only permissions and synchronized mode
/home/nfs/ 10.1.1.55(rw,sync,no_root_squash) export /home/nfs directory for host with an IP address 10.1.1.55with read, write permissions, synchronized mode and the remote root user will be treated as a root and will be able to change any file and directory.
/home/nfs/ *(ro,sync) export /home/nfs directory for any host with read only permissions and synchronized mode
/home/nfs/ *.linuxconfig.org(ro,sync) export /home/nfs directory for any host within linuxconfig.org domain with a read only permission and synchronized mode
/home/nfs/ foobar(rw,sync) export /home/nfs directory for hostname foobar with read, write permissions and synchronized mode

Why Cloud Hosted Email?

Why Cloud Hosted Email?

If you already own a domain name and use it for your email accounts, our cloud hosted email platform enables you to do everything you currently do with email, contacts and calendars, but will enable you to do it from anywhere simply by logging into your mailbox from any device connected to the Internet.

If you don’t currently use your domain email, or haven’t even registered a domain yet to do so, you really ought to. This article in our support section tells you why you should!

In addition to simply logging in to a cloud hosted mail client, with your email address and password, you can also set up your account up on whichever desktop mail client you use [Outlook etc], your smart phone [iPhone, Android etc], or tablet device [iPad etc], and your incoming and outgoing messages will automatically synchronize with each other regardless of which device or application you are using at the time.

What is a Hosted PBX?

What is a Hosted PBX?

A Hosted PBX is a private branch exchange (PBX) delivered as a hosted service. It’s also known as a Virtual PBX and the advantages companies that use it experience are the elimination of installation, operation and maintenance costs of their VoIP PBX as their VoIP service provider hosts their PBX for them.

A Hosted PBX still allows companies to utilize and take complete advantage of their phone system’s feature set such as voicemail, faxing, automated greetings, conferences and so on.

Companies that offer Hosted PBX’s as a service to their customers handle the call routing or switching as well as all maintenance involved in the hosted PBX service.

There are three ways that a Hosted PBX works; either over the Public Switched Telephone Network (PSTN) over the Internet (hosted IP PBX via Internet Telephony or Voice Over IP, VoIP) or with a combination of the two.

Key benefits of a Hosted PBX Solution

  • Initial and Ongoing cost savings – there’s no need for a large investment before installing your phone system and also the maintenance cost of your phone system is much lower as you don’t need to hire someone inhouse to operate and maintain your PBX.
  • Eliminate office boundaries – employees can work from anywhere with a virtual office phone system. Ideal for home-workers and salespeople who are constantly on the move.
  • Boost of corporate image – by using a hosted phone system small businesses can still give the impression of being a large organization with a professional phone system.
  • Scalability – with a virtual phone system businesses can add or remove lines and extensions as they grow
  • Easy to use – since there’s no end-user management involved with a virtual PBX, it’s easier to use than a traditional phone system.

What is a fully qualified domain name (FQDN)?

What is a fully qualified domain name (FQDN)?

A fully qualified domain name (FQDN) is the complete domain name for a specific computer, or host, on the Internet. The FQDN consists of two parts: the hostname and the domain name. For example, an FQDN for a hypothetical mail server might be mymail.somecollege.edu. The hostname is mymail, and the host is located within the domain somecollege.edu.

In this example, .edu is the top-level domain (TLD). This is similar to the root directory on a typical workstation, where all other directories (or folders) originate. (Within the .edu TLD, Indiana University Bloomington has been assigned the indiana.edu domain, and has authority to create subdomains within it.)

The same applies to web addresses. For example, www.indiana.edu is the FQDN on the web for IU. In this case, www is the name of the host in the indiana.edu domain.

When connecting to a host (using an SSH client, for example), you must specify the FQDN. The DNS server then resolves the hostname to its IP address by looking at its DNS table. The host is contacted and you receive a login prompt.

If you are using only the hostname (without the domain information) to connect to a server, the application you’re using may not be able to resolve the hostname. This can happen if either the DNS suffix search order in your computer’s TCP/IP properties is incorrect, or the DNS table is corrupted. In these cases, entering the host’s FQDN will allow DNS to locate the server. Also, if you are trying to connect to a remote host that is not local to your Internet service provider (ISP), you will probably have to use the FQDN. For example, it’s unlikely that a DNS server at IU would have a listing for remote hosts at another university or an unrelated ISP.

What is a CNAME record

What is a CNAME record?

CNAME stands for Canonical Name. CNAME records can be used to alias one name to another.

For example, if you have a server where you keep all of your documents online, it might normally be accessed through docs.nocroom.com. You may also want to access it through documents.nocroom.com. One way to make this possible is to add a CNAME record that points documents.nocroom.com to docs.nocroom.com. When someone visits documents.nocroom.comthey will see the exact same content as docs.nocroom.com.

Add a CNAME record

To use CNAME records, select CNAME from the Add Record drop down in the advanced editor. Then enter the hostname you would like to alias from and the fully-qualified domain name you would like to alias to. You may also enter @ in the Alias for field to represent the domain itself.

For example, if the domain were nocroom.com and you wanted www.nocroom.com to point to nocroom.com you could put www in the name field and @ in the alias for field.

What is Autodiscover

So what is Autodiscover?

Autodiscover is a mechanism that allows users to easily configure their email client knowing only their email address and password. Autodiscover also enables additional features for Microsoft Exchange including:

  • Downloading the Offline Address Book
  • Viewing Free/Busy time in your calendar
  • Configuring your Out-of-Office

E-mail clients that make use of Autodiscover includes Outlook 2007, Outlook 2010, Outlook 2013/16, Outlook 2011, Mac Mail, Entourage 2008 WSE and many smartphones.

Note: Autodiscover for Computer House Email configures email clients for IMAP and SMTP, however does not work in Outlook 2011 or Mac Mail.

Autodiscover is simple to set up for your domain, it only requires that you create a CNAME resource record. CNAME records are a type of DNS record, other types include A records and MX records.

Note: We recommend that you create an Autodiscover CNAME record for every domain on your account, this includes domain aliases and accepted domains.

Creating a CNAME DNS record:

Contact your DNS hosting provider and ask them to create the following CNAME record. If you have access to the control panel for your DNS, you can make this change yourself.

Hostname: autodiscover

Record Type: CNAME

TTL: 300 (if required)

Address: autodiscover.emailsrvr.com.

Example:

Setup a DNS record for Autodiscover

Setup a DNS record for Autodiscover

Note: Depending on your DNS provider’s requirements, you may need to add the fully qualified domain name as your hostname e.g. if your domain is example.com your hostname would be autodiscover.example.com. instead of autodiscover.

It could take 24 hours or more for this change to take effect, even though most DNS providers update their DNS records within three hours. You may want to ask your DNS provider what their “update time” is.

Checking for the Autodiscover CNAME record:

To confirm your e-mail client, e.g. Outlook 2013, has access to your new Autodiscover record perform the following actions from your Windows computer:

    Click the Windows Start button and select Run.

    Type “nslookup” and press the Enter key on your keyboard.

    Type in the name of the hostname you created above (e.g., autodiscover.example.com), and press the Enter key on your keyboard.

    If your records were correctly created, you should receive results similar to the following:

Name: autodiscover.emailsrvr.com

Address:  184.106.31.93

Aliases: autodiscover.example.com

Type quit and hit enter to exit nslookup.

Internal DNS and Autodiscover:

If you are running Windows Server 2003 or 2008 with internal DNS, you will need to perform the following steps:

  1.     On your remote desktop session, select Start / Programs / Administrative Tools / DNS.
  2.     Right-click your domain name and select New Alias (CNAME).
  3.     Under Alias Name enter: autodiscover
  4.     Under Fully qualified domain name (FQDN) for target host enter: autodiscover.emailsrvr.com
  5.     Click the Ok button.

What is Top-Level Domain (TLD)

The top-level domain (TLD), sometimes called the internet domain extension, is the very last section of an internet domain name, located after the last dot, to help form a fully qualified domain name ( FQDN).

For example, the top-level domain of nocroom.com and google.com are both .com.

What Is the Purpose of a Top-Level Domain?

Top-level domains serve as an instant way to understand what a website is about or where it’s based.

For example, seeing a .gov address, like in www.whitehouse.gov, will immediately inform you that the material on the website is centered around government.

A top-level domain of .ca in www.cbc.ca indicates something about that website, in this case, that the registrant is a Canadian organization.

What Are the Different Top-Level Domains?

A number of top-level domains exist, many of which you’ve probably seen before.

Some top-level domains are open for any person or business to register, while others require that certain criteria be met.

Top-level domains are categorized in groups: generic top-level domains (gTLD)country-code top-level domains (ccTLD)infrastructure top-level domain (arpa), and internationalized top-level domains (IDNs).

  • .com (commercial)
  • .org (organization)
  • .net (network)
  • .name (name)
  • .biz (business)
  • .info (information)

Additional gTLDs are available that are called sponsored top-level domains, and are considered restricted because certain guidelines must be met before they can be registered:

  • .int (international): Used by international organizations for treaty-related purposes, and requires a United Nations registration number
  • .edu (education): Limited to educational institutions only
  • .gov (government): Limited to U.S. governmental entities only
  • .mil (military):  Limited to the U.S. military only
  • .jobs (employment): Must be registered under the legal name of a company or organization
  • .mobi (mobile): Might have to adhere to mobile-compatible guidelines
  • .tel (Telnic): Limited to hosting related to contact information, not websites

 

Country Code Top-level Domains (ccTLD)

Countries and territories have a top-level domain name available that’s based on the country’s two-letter ISO code. Here are some examples of popular country code top-level domains:

  • .us: United States
  • .ca: Canada
  • .nl: Netherlands
  • .de: Germany
  • .fr: France
  • .ch: Switzerland
  • .cn: China
  • .in: India
  • .ru: Russia
  • .mx: Mexico
  • .jp: Japan
  • .br: Brazil

The official, exhaustive list of every generic top-level domain and country code top-level domain is listed by the Internet Assigned Numbers Authority (IANA).

 

Infrastructure Top-Level Domains (arpa)

This top-level domain stands for Address and Routing Parameter Area and is used solely for technical infrastructure purposes, such as resolving a hostname from a given IP address.

 

Internationalized Top-Level Domains (IDNs)

Internationalized top-level domains are top-level domains that are displayed in a language-native alphabet.

For example, .рф is the internationalized top-level domain for the Russian Federation.

How Do You Register a Domain Name?

Internet Corporation for Assigned Names and Numbers (ICANN) is in charge of managing top-level domains, but registration can be done through a number of registrars.

Some popular domain registrars you may have heard of include GoDaddy1&1NetworkSolutions, and Namecheap.
