Files opening slowly using XFCE desktop on Ubuntu Server 12.04

My main server runs Ubuntu Server 12.04 with the XFCE desktop (I use Teamviewer for remote access) and has been happily sipping electricity for months with no issues except one – files and folders would open VERY slowly the first time you accessed them after boot.  After that there would be no issue.  Finally after a lot of digging I have come up with a solution.


I found that there was actually two issues going on at the same time.  The first one was permissions.  I noticed that when Thunar (file manager) was opened as root there was no speed issue but as a normal user it was very slow.  To rectify this I set the ‘group’ permission to read/write and voila it did speed up.  The speed was still a bit slow for my liking so I kept on digging.

The main culprit turned out to be two packages called gvfs-fuse and gvfs-backend.  Gvfs is a userspace virtual filesystem which as it turns out makes Thunar run really slowly.  Remove these two packages and watch your files and folders open significantly faster.

Hope this helps someone with a similar problem.

Ubuntu 12.10 released – so what?

Ubuntu released its new server operating system 12.10 on October 18th. Having tried the new software I would say it is a solid release but I would also say – so what?

I love Ubuntu and use Ubuntu Server 12.04 LTS for my own work systems and find it a very capable operating system but I do not understand why Canonical insist on releasing new server software every 6 months.

Home users might want to upgrade their systems every six months to get the most recent software versions, however businesses will never do this and are going to stay with the LTS versions.  None of the other Linux big players (e.g Novell, Red Hat etc) do this so it begs the question who are Ubuntu aiming this (and future 18 month supported) versions at?


Why not have less versions of the server software and make them all LTS and bring out service packs (if and when required) rather than new operating systems every six months? Six months is not enough time to iron out most of the bugs (you will never get rid of all bugs) and check everything is working as it should.

If Ubuntu is serious about adoption within the enterprise market then its release schedule has to change.

Do you agree?

How to install a desktop on Ubuntu server 12.04

When you install Ubuntu Server 12.04 the default is for it to install with no desktop which is usually fine however there are times when you might want a desktop environment so today I will show you how to install one.


If you want the default Gnome 2 desktop then type:

sudo apt-get install ubuntu-desktop

For Xfce type:

sudo apt-get install xubuntu-desktop

If you fancy KDE instead then type:

sudo apt-get install kubuntu-desktop

And for something very lightweight (LXDE – one of my favourites) then type:

sudo apt-get install lubuntu-desktop

All the above commands install all the desktop addons like Evolution, Libreoffice etc so if you would rather not have them then add  –without-recommends.  So for example the default Gnome 2 command will become:

sudo apt-get install –without-recommends ubuntu-desktop

How to set up a DNS server on Ubuntu Server 12.04 LTS


Today I will show you how to set up a DNS server on Ubuntu Server 12.04 LTS.

The first thing to do is to install the software we need, in this case we need the bind9 package. Open up a terminal and type:

sudo apt-get install bind9

Once installed it is time for some configuring. The first file we need to configure is named.conf.local. So in the terminal type:

sudo nano /etc/bind/named.conf.local

I have used nano to open up the file but use whichever text editor you are happy with. Insert the following code into the file:

# This is the zone definition. replace example.com with your domain name
zone “comtech.com” {
type master;
file “/etc/bind/zones/comtech.com.db”;
};

# This is the zone definition for reverse DNS. replace 0.168.192 with your network address in reverse notation – e.g my network address is 192.168.0
zone “1.168.192.in-addr.arpa” {
type master;
file “/etc/bind/zones/rev.0.168.192.in-addr.arpa”;
};

Replace comtech.com with the name of your DNS domain (this is not the same as an active directory domain but rather a name for your DNS zone).

Next up is the options file. In the terminal type:

sudo nano /etc/bind/named.conf.options

Within this file we need to modify the forwarder with the address of your ISP’s DNS servers. So modify the file adding the following:

forwarders {

194.72.0.114;
194.74.65.69;
};

Replace the addresses above with the addresses of your ISP’s DNS servers.

Now we need to add the zones file:

sudo mkdir /etc/bind/zones

And then configure it:

sudo nano /etc/bind/zones/comtech.com.db (replace comtech.com with your DNS domain).

Add the following code to the file:

// replace example.com with your domain name. do not forget the . after the domain name!
// Also, replace ns1 with the name of your DNS server
comtech.com. IN SOA chris-server.comtech.com.
// Do not modify the following lines!
2006081401
28800
3600
604800
38400
)

// Replace the following line as necessary:
// ns1 = DNS Server name
// mta = mail server name
// example.com = domain name
comtech.com. IN NS chris-server.comtech.com.
comtech.com. IN MX 10 mta.example.com.

// Replace the IP address with the right IP addresses.
www IN A 192.168.1.4
mta IN A 192.168.0.3
chris-server IN A 192.168.1.4

In the above code replace the following:

comtech.com with your DNS domain name,

192.168.1.4 with your static DNS server address,

chris-server.comtech.com with your computers hostname.dns-domain,

mta is your mail server (if you have one). If you do modify the IP address to show this.

Next we have to create the reverse DNS zone file:

sudo nano /etc/bind/zones/rev.1.168.192.in-addr.arpa

Add the following code:

//replace example.com with your domain name, ns1 with your DNS server name.
// The number before IN PTR example.com is the machine address of the DNS server
@ IN SOA chris-server.comtech.com admin.comtech.com. (
2006081401;
28800;
604800;
604800;
86400
)

IN NS chris-server.comtech.com.
1 IN PTR comtech.com

All that is left to do is restart bind:

sudo service bind9 restart

Don’t forget to test the new configuration:

dig comtech.com

NOTE:

If you are unable to restart the bind9 service run the command named -g 53 which will give you a list of any configuration errors.
