Hello,
I'm using Keealived for configuration:
OpensSIPs1 IP 1.2.3.4
OpenSIPs2 IP 5.6.7.8
Virtual IP: 10.11.12.13
OpenSIPs1:
*keepalived.conf*
vrrp_script check_sip {
*script "/etc/keepalived/node01.sh"*
interval 3
fall 2
rise 2
}
vrrp_instance VI_OS {
state MASTER
interface eth0
virtual_router_id 1
advert_int 1
*notify /etc/keepalived/opensips.sh*
virtual_ipaddress {
10.11.12.13 dev eth0
}
track_script {
check_sip
}
}
each time there is a change in the servers status, keepalived ejecute
opensips.sh script
*node01.sh*
#!/bin/bash
node01=1.2.3.4
node02=5.6.7.8
*return_code=0*
timeout 2 sipsak -s sip:$node01:5060
exit_status=$?
if [[ $exit_status -eq 0 ]]; then
echo "sip ping successful to node01 [$node01]"
exit $return_code
fi
timeout 2 sipsak -s sip:$node02:5060
exit_status=$?
if [[ $exit_status -eq 0 ]]; then
echo "sip ping successful to node02 [$node02]"
return_code=1
fi
echo "return code [$return_code]"
exit $return_code
*opensips.sh*
#!/bin/bash
TYPE=$1
NAME=$2
STATE=$3
case $STATE in
"MASTER") /usr/sbin/opensipsctl fifo dlg_set_sharing_tag_active vip
/usr/sbin/opensipsctl fifo nh_enable_ping 1

exit 0

exit 1
;;
esac
in this file I move the sharing tag and pinging NAT in the MASTER status
and remove in BAKCUP and FAULT status
OpenSIPs2:
*keepalived.conf*
vrrp_script check_sip {
script "/etc/keepalived/node02.sh"
interval 3
fall 2
rise 2

vrrp_instance VI_OS {

Then you have to install sipsak and change your iptables configuration.

Hi,
Can you show us that how you are creating dialogs ? and where are you
setting your sharing tag, like this -
set_dlg_sharing_tag("vip");
Thank you
