Hi Sir,
Hope you are in good health.
I need you help to solve below error.
I have installed a fresh copy of trixbox 2.6.1 CE and then access through GUI and getting below error:
Unable to connect to remote asterisk (does /var/run/asterisk/asterisk.ctl exist?
However I have installed asterisk:
yum -y install asterisk -devel
Upgrade Kernel
yum -y install kernel-dev
then check with below command asterik -r
and its showing asterisk is running
But when I access through GUI I still getting same error
Unable to connect to remote asterisk (does /var/run/asterisk/asterisk.ctl exist?

sam4u1,
That sounds unusual. Trixbox is supposed to work right away without too much fiddling.
Have you looked at this thread on the Trixbox forum?

Did it work before you did those installs with yum? Trixbox should have installed Asterisk, you should not have to use yum to install it afterward.
Let us know what you've tried and we'll see if we can help you out.
