[asterisk-users] Having problem getting Asterisk to work on CentOS 7

Some background information.

I have used Debian with Asterisk for several years. Have encountered zero
problems.
I am now trying to setup an Asterisk on a CentOS7 box using VMWare Workstation.
I am brand new to CentOS and RHEL so I may be missing something obvious.

I am installing CentOS Minimal Install and Asterisk from Source. (I have
installed Asterisk from Source on Debian hundreds of times without any
problems).
After installing CentOS (only root user), I update CentOS. I then install the
CentOS "Development Tools".
Also install, I install net-tools and wget.

After that, I am following the Wiki pages for Asterisk from Source.
https://wiki.asterisk.org/wiki/display/AST/Installing+Asterisk+From+Source
Retrieve the asterisk-13-current.tar.gz and the pjproject-2.6.tar.bz2

I uncompress them, run the asterisk install_prereq script to install all
required packages.
I configure PJPROJECT, make dep, make, make install, and ldconfig

After that, I install asterisk
./configure
make menuselect
make
make install
make samples
make progdocs
make config

After that, I modify the asterisk conf files for a couple pjsip endpoints and
turn on debugging and verbosity. Copying settings from another box which is
working.

I am seeing two different issues....

First, when I restart the box, the asterisk process is present. However,
it's not writing anything to the log files so it seems to be stuck. Any
idea why running Asterisk as a service after the make config would not seem to
fully start up?

Second, I stop the asterisk service. Make sure asterisk process is not present.
Then, I start it up manually going to the console. Everything is running. I
see information written to the asterisk log files. However, I try to connect
phones to this and it does not work. I used tcpdump to verify the SIP packets
are making it to the CentOS box, however Asterisk is not seeing the SIP
messages.
I run netstat -apn | grep -i asterisk and see Asterisk udp with port 5060.
The one thing I notice is my Debian installations have always been eth0. CentOS
is using the newer ens33. Might this cause a proble?
Any suggestions?

Have a great day!

Dan

You mentioned starting asterisk manually. Do you do that with the proper
permissions (assuming you do run Asterisk as a non-root user, as you
should). Any chance asterisk does not have write permissions to the log
files?

Failing that, try strace.

  strace -p $PID_OF_ASTERISk

Maybe also add -f and / or -o if there's too much output.

Hello,

Did you disable selinux ? It usually causes troubles when starting 
asterisk as a service. You can do this with : setenforce 0 (this will 
not totally disable selinux, but switch it to a permissive mode).

For your second point, maybe you should check that firewalld is either 
stopped or configured properly. By default it has  quite restrictive rules.

Best regards

Jean Aunis

[asterisk-users] Having problem getting Asterisk to work on CentOS 7

Thank you Tzafrir.

I had been using different users in earlier attempts to make this work.  Decided
to try everything where root is the only user, simply to verify it's
working.

For problem 2, where asterisk is writing to the log but doesn't seem to
receive the SIP packets even though tcpdump indicates they are making it to the
box on 5060, I am starting asterisk while logged in as root.
/usr/sbin/asterisk -vvvvvvvvdddddddc


For problem 1, where it seems to be stuck when running as a service, I simply
reboot the machine.  Then I log it as root and notice it's not writing to
the log.

When running it as a service (after restart).  Here is what the output from
strace -p $PID_OF_ASTERISK

You mentioned starting asterisk manually. Do you do that with the proper
permissions (assuming you do run Asterisk as a non-root user, as you should).
Any chance asterisk does not have write permissions to the log files?

Failing that, try strace.

  strace -p $PID_OF_ASTERISk

Maybe also add -f and / or -o if there's too much output.

[asterisk-users] Having problem getting Asterisk to work on CentOS 7

Thank you Jean.

I changed selinux to permissive in the /etc/selinux/config and restarted. 
Asterisk was able to start up.  One oddity though, I now see two different pids
for asterisk (pgrep asterisk).  Is this to be expected or do I still have
something wrong?

For my second issue, after stopping firewalld, SIP traffic is now making it
through to Asterisk.

I need to research both selinux and firewalld some more.  They are both new to
me.

Have a great day!

Dan

Hello,

Did you disable selinux ? It usually causes troubles when starting asterisk as a
service. You can do this with : setenforce 0 (this will not totally disable
selinux, but switch it to a permissive mode).

For your second point, maybe you should check that firewalld is either stopped
or configured properly. By default it has  quite restrictive rules.

Best regards

Le 14/03/2017 ? 17:45, Dan Cropp a ?crit :
Some background information.

I have used Debian with Asterisk for several years.  Have encountered zero
problems.
I am now trying to setup an Asterisk on a CentOS7 box using VMWare Workstation. 
I am brand new to CentOS and RHEL so I may be missing something obvious.

I am installing CentOS Minimal Install and Asterisk from Source.  (I have
installed Asterisk from Source on Debian hundreds of times without any
problems).
After installing CentOS (only root user), I update CentOS.  I then install the
CentOS "Development Tools".
Also install, I install net-tools and wget.

After that, I am following the Wiki pages for Asterisk from Source.
https://wiki.asterisk.org/wiki/display/AST/Installing+Asterisk+From+Source
Retrieve the asterisk-13-current.tar.gz and the pjproject-2.6.tar.bz2

I uncompress them, run the asterisk install_prereq script to install all
required packages.
I configure PJPROJECT, make dep, make, make install, and ldconfig

After that, I install asterisk
./configure
make menuselect
make
make install
make samples
make progdocs
make config

After that, I modify the asterisk conf files for a couple pjsip endpoints and
turn on debugging and verbosity.  Copying settings from another box which is
working.

I am seeing two different issues....

First, when I restart the box, the asterisk process is present.  However,
it's not writing anything to the log files so it seems to be stuck.  Any
idea why running Asterisk as a service after the make config would not seem to
fully start up?

Second, I stop the asterisk service.  Make sure asterisk process is not present.
Then, I start it up manually going to the console.  Everything is running.  I
see information written to the asterisk log files.  However, I try to connect
phones to this and it does not work.  I used tcpdump to verify the SIP packets
are making it to the CentOS box, however Asterisk is not seeing the SIP
messages.
I run netstat -apn | grep -i asterisk and see Asterisk udp with port 5060.
The one thing I notice is my Debian installations have always been eth0.  CentOS
is using the newer ens33.  Might this cause a proble?
Any suggestions?

Have a great day!

Dan

Generally before advising that, check if this is the error:

  tail -f /var/log/audit/audit.log

and try the command.

Is there any open bug for a security policy for Asterisk?
