Install Kannel in RedHat Enterprise Linux 6

Did you try:

AS root:

yum install kannel

OR as any user as

sudo yum install kannel

If above doesn't work you can also try as root

rpm -ivh ftp://ftp.univie.ac.at/systems/linux/dag/redhat/el6/en/i386/dag/RPMS/kannel-1.4.2-1.el6.rf.i686.rpm

thanks. if you more information about kannel post in a comment
thanks

Welcome.  Basically this is the order you should follow.

1.  Try using yum that does everything for you the best way.
2.  Sometimes you don't have a particular RPM available through yum so you have to get it through some website.  Download from the most authentic website.  If you can download it from the actual kannel website in your case, that would be great.

I have a modem gsm Wavecom Q2303A module, but i don't now how to configure on red hat enterprise linux server 6.

please help me
thanks

I wish I could.  Open a new question in as many appropriate zones as possible because you will have hard time finding someone who knows it.

thank you so much

You are welcome :)
