Using gammu to connect to a mobile phone to send SMS

msverman — Tue, 08 Dec 2015 09:51:58 +0000

Install Gammu

Installing gammu is surprisingly easy (once again thanks to the wonders of apt-get), just use the following command:

sudo apt-get install gammu

Hard wasn’t it?

OK now it’s time to plug your phone in and see if we can get things talking. With the phone connected, type the following command:

lsusb

you should now see your phone listed as a device – for example:

Bus 001 Device 002: ID 0421:0802 Nokia Mobile Phones

if not – make sure your cables and power are all good and try again.

The gammu installation comes with some example configuration files which are worth using as a starting point – if nothing else they help you to understand how gammu can be configured so that you can tailor a solution for your needs. These are located in
/usr/share/doc/gammu/examples (in gZip archives).

Copy the gammurc file to /etc/gammurc :

sudo cp /usr/share/doc/gammu/examples/config/gammurc /etc/gammurc

Now edit /etc/gammurc to specify your port and connection type (this will vary based upon where/how you have things plugged in and what sort of cable/interface your phone is using). The settings for mine are:

port = /dev/ttyACM0
connection = dku5

Save this config and from the shell type:

gammu –identify

you should now be presented with some information regaqrding your phone such as:

Manufacturer : Nokia
Model : 7200 (RH-23)
Firmware : 3.110 T (18-03-04)
Hardware : 0903
IMEI : 353363000813894
Original IMEI : 353363/00/081389/4
Manufactured : 04/2004
Product code : 0514143
UEM : 16

If this is the case then you have got gammu up and running and can send yourself a test message with the following command:

echo “boo” | gammu –sendsms TEXT [recipient mobile number]

Error : /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory

msverman — Tue, 04 Feb 2014 04:02:27 +0000

I tried to run a corporate client on centos the following error occured

[root@localhost crclient]# ./crclient -u xxx
-bash: ./crclient: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory

Problem :

This error occured due to excuting a 32 bit application which does not find the library /lib/ld-linux.so.2.

This is because the 64-bit operating system have excluded the 32-bit packages during installaion process, when try to excute the third party binaries you get above error.

Solution :

Install glibc.i686 using yum.

[root@localhost centos6]# yum install glibc.i686

Another app is currently holding the yum lock; waiting for it to exit…

msverman — Mon, 14 Oct 2013 09:48:44 +0000

Today I tried to install fonts for GNome desktop and unable to install due yum lock in my server that is load with centos

Error :

[root@localhost ~]# yum install xorg-x11-font*
Loaded plugins: fastestmirror, refresh-packagekit, security
Existing lock /var/run/yum.pid: another copy is running as pid 2600.
Another app is currently holding the yum lock; waiting for it to exit…
The other application is: yum
Memory : 21 M RSS (1.2 GB VSZ)
Started: Mon Oct 14 12:19:29 2013 – 08:47 ago
State : Sleeping, pid: 2600

First i attempt to kill the process

# kill -9 2600

the process could not be stopped

Second i attempt to kill all yum process

# killall -9 yum

still the process could not be stopped

then i shutdown my server and switched on again and still the same result.

finally i remove the yum.pid 2600

after this yum started working fine.

Final solution if you fail to stop the process :

#rm -f /var/run/yum.pid 2600

then update your yum

# yum -y update

Make sure that yum-updatesd is started :

#/etc/init.d/yum-updatesd status

# /etc/init.d/yum-updatesd start

Header V3 DSA signature: NOKEY, key ID 37017186

msverman — Thu, 23 Jun 2011 11:06:02 +0000

To resolve this key problem in RHEL, I installed the public release key

#rpm –import /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

This allows you to install from the local source.Copy and install all the packages from the RHEL5 DVD’s to a directory to use ‘YUM’ from local repository.

Importing the key as outlined above enabled me to install the packages without getting the following error:

warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID 37017186.

Note : RHEL DVD’s help me in completing the installation in local server without internet connection.
