How to install Gammu on Lubuntu 14.04

linux insideMy friend bought Wavecom 1306B gsm modem for his campus last task. He use Windows XP and trying to use the modem without success. He try it on his friend laptop that run Windows 7 also not work and he ask me to try it. Just to test the modem. If its not work might then He will return it to the seller.

I use Lubuntu 14.04 but I think the instruction would be same for Ubuntu 14.04 variant :

Cheap VPS that support FreeBSD, OpenBSD, NetBSD and many more – KVM SSD technology

Since I retire from my old company I don’t have access to FreeBSD server that I manage. I use FreeBSD since version 4.7 till latest version 9.0 (last version when I retire). The only option I do is using VirtualBox.

With less access to server make my memory get weak but I still get my old post here work when I need together with video made. Last week a friend told me about new VPS provider called Vultr that give great deal.


Start from $5/month or you can choose hourly charge you can choose many location available such as Dallas, Chicago, New Jersey, Los Angeles, Seattle, Washington for USA preferred location. Other server location are Amsterdam, London, Frankfurt, Paris, German for Europe vps preferred location or Sydney and Tokyo for Asia consumer (at the of writing I see 14 location available). I hope in future they can add other for Asia, Singapore for example.

vps with 14 location available; support usa, europe and asia region

Operating System

By default Vultr provide two architecture; 32 and 64 bit. Each bit have their own ‘default’ OS like CentOS, Ubuntu, Debian, FreeBSD and Windows. In 64 bit OS section you have ‘custom iso’ section. This section dedicated for other OS that not available on the list. So far I have try install DragonFlyBSD, FreeBSD and OpenBSD and other Linux variant like Slackware, OpenSuse and Fedora using custom iso and working well.


Price scheme also good I my opinion. I can tell my student to do their experiment using this service. They can get more memory with same price as other provide like DigitalOcean (but DO not provide custom iso).

vps default operating system available plus custom iso and snapshot then price option

Custom Iso Service

custom _iso_vps

Vultr provide custom iso that let you use iso with maximum 5192MB in size, that could be DVD size. Very spoiling me and my imagination. I can do my experiment with so many scenario. For example I can deploy linux distribution that specialize in disk management like gparted the followed by install Slackware OS or vice versa start with OS installation then resize the disk with gparted for new swap and more.

Server Type

I see it from benchmark experiment. I can experiment for server recipe that might involve database load balancing, high availability, data server like ftp and multi processor utilization operation.

cheap vps that provide different type of server; performance series, storage series and multicore series

KVM and SSD Technology

I love KVM since I never face problem with it. Using SSD for fast operation and I think I prefer to use VPS than my ‘dedicated’ server that utilize IDE for some work.

Last time I make deposit, the provider match my deposit 1:1. $10 get $10 so I got $20 in my account. Good for one instance for 4 month or I can switch the operating system each month ūüôā

My friend told me if the provider maybe try to compete with Digital Ocean so they give same price. I don’t care. Competition is good for customer like us. Give more location, good up time and low latency then your customer ‘soul’ is yours ( Mortal Combat ).

MySQL Tuner on FreeBSD 9.2

Variables to adjust:
query_cache_size (>= 8M)
thread_cache_size (start at 4)

Interesting…. as I see this job is not just set and forget but must be running regularly to identified a running process.

Install PHP 5.2.17 on CentOS 5.10

CentOSAnother server came with specific hardware that require me to install CentOS 5.10 64 bit with base only package. Since CentOS 5 use PHP 5.1 by default so I decide to find a way for PHP 5.2.17 (latest version of PHP 5.2 generation).


I use Jason package from

# nano /etc/yum.repos.d/utter-ramblings.repo
fill these lines :

name=Utter Ramblings


Make sure to change to for baseurl if you use 32 bit.

Install PHP and friends

PHP 5.2.17

# yum install php php-mysql


# yum install mysql-server

Run as service

# chkconfig httpd --add
# chkconfig  httpd  on --level 235
# chkconfig  mysqld --add
# chkconfig mysqld on --level 235

2  =  Multi-user mode console logins only (without networking)
3  =  Multi-User mode, console logins only
5  = Multi-User mode, with display manager as well as console logins (X11)

Checking if already set as service

# chkconfig --list mysqld
mysqld             0:off    1:off    2:on    3:on    4:off    5:on    6:off
# chkconfig --list httpd
httpd              0:off    1:off    2:on    3:on    4:off    5:on    6:off

Checking installed httpd and mysql :

# rpm -qa | grep httpd

# rpm -qa | grep mysql


P.S : in case you got error (refused connection) then iptables need to told about this service :

# iptables -I INPUT -p tcp -m tcp --dport 80 -j ACCEPT
# service iptables save

Saving firewall rules to /etc/sysconfig/iptables:          [  OK  ]
# service iptables restart
Flushing firewall rules:                                   [  OK  ]
Setting chains to policy ACCEPT: filter                    [  OK  ]
Unloading iptables modules:                                [  OK  ]
Applying iptables firewall rules:                          [  OK  ]
Loading additional iptables modules: ip_conntrack_netbios_n[  OK  ]


Last check : date

# date
Rab Nov 12 18:20:19 WIT 2014

Checking BIOS time I see no error.

# rpm -qa | grep ntp

Since another process lock yum, I use quick way :

# date 111210212014
Rab Nov 12 10:21:00 WIT 2014

Yes, that command use following format

date MMDDhhmmYYYY

MM -> month (in two digit)

DD -> date (in two digit)

hh -> hour (in 24 hour format)

mm -> minutes (in 2 digit)

YYYY -> year (in 4 digit)

Check again after issue command.

# date

Rab Nov 12 10:25:21 WIT 2014

Yes, the result is match.

I’ll continue with ntp next time.

For quick dns setting I use maradns.

Well, I need to set sender address ūüôā
