Hello,
I have solved this problem :) As you wrote sipp needs root rights to create
raw socket and send rtp streams. Using sudo is a good idea.
After modified "function execute_background" in exec_call.php I realized two
problems caused by using sudo.
1. "Function getNewControlPort" went wrong because output of netstat hides
the PID of sipp process. Sudo need again...
2. Screen file in /tmp/sipp... is created by root. So this file is not
writeable by www-data user it means screen file remained empty until end of
sipp process. (screen file is filled by sipp via signal and read by ajax
periodically). Sudo need again :)
It has to modify the following lines:
exec_call.php
{function execute_background}
$ppid = shell_exec("export TERM=vt100; (nohup sudo $command
; echo $? > $exit_code_file) 2> $error_file > $output_file & echo $!");
{function getNewControlPort}
$command = "sudo netstat -p --numeric-ports -l --udp | grep
\"".$pid."/sipp\" | grep -o \"\:".$highest2digits."[0-9]\+\" | grep -o
\"[0-9]\+\"";
get_screen.php
exec("sudo kill -USR2 $pid");
exec("sudo kill -USR2 $pid");
Regards,
Zsolt

Hello,
I installed sipp web frontend and it runs normally with the standard uac
scenario on my web server. I want to use the uac_pcap scenario in order to
send RTP streams. This uac_pcap scenario runs normally with command lines
but it doesn't work with sipp web. I tried many things to succeed but
without results.
I created my own test and loaded the standard scenario uac with media. I
tried to solve my first problem (cf. fig1) with adding "sudo" ( package sudo
is installed and sudoers is configured)* in the function execute_background
(file exec_call.php) at the following line :
$ppid = shell_exec("export TERM=vt100; ( sudo nohup $command ; echo $? >
$exit_code_file) 2> $error_file > $output_file & echo $!");
Now, I see an empty scenario screen (cf.fig 2) in the 2 cases (uac and uac
with media). Sipp web doesn't display messages.
Please, can you give me some help. I really need to run uac_pcap on my web
server.
Best Regards,
Ben
N.B: I work on a CentOS with sipp-3.0.src.tar version.
