A few points.
Firstly, If you are going to run 2 different instances on the same server, they should have different ports (e.g. 5060 for the 1st instance and 5062 for 2nd).
Secondly, if you are trying to resolve 2 different Local IPs to the same server (in your case 192.168.1.112 and 192.168.1.113), one of any of these should happen: 1. you should either have 2 network card interfaces in your server, or 2. Linux does this thing where it is able to split a single (physical) NIC interface into seperate virtual interfaces (e.g. for a single interface * eth0* splits it into *eth0:0* for the 1st virtual interface and *eth0:1* for the 2nd, etc). The process is called *IP aliasing*. You should then allocate the 2 local IPs to the 2 virtual interfaces like so: eth0:0 -> 192.168.1.112, and eth0:1 -> 192.168.1.113
commands are something like this:
ifconfig eth0 *XXX.XXX.XXX.XXX* netmask 255.255.255.0 broadcast * XXX.XXX.XXX*.255 ifconfig eth0:0 192.168.1.112 netmask 255.255.255.0 broadcast 192.168.1.255 ifconfig eth0:1 192.168.1.113 netmask 255.255.255.0 broadcast 192.168.1.255
route add -host *XXX.XXX.XXX.XXX* dev eth0 route add -host 192.168.1.112 dev eth0 route add -host 192.168.1.113 dev eth0 route add default gw <Gateway IP>
where *XXX.XXX.XXX.XXX* in the 1st instance refers to another local IP e.g. 192.168.1.3. (I am no Linux guru so maybe the gurus here could pipe in). :)
Method 1 is probably the simpler and more straight-forward, but if you can't afford 2 NICs I don't think Method 2 will be too difficult either.
Simply putting the entries in etc/hosts is not enough as the server needs to be able to identify them as 2 separate instances. This is why you are getting that error - it's because only one interface was identified and that has already been "bound" to the first Local IP (192.168.1.112).
Also, if I understand your *ifconfig* output correctly, then this is not setup correctly. You seem to be mixing private and public IP addresses. If you are going through a router or NATed environement you don't need to assign the external interfaces to the NIC(s), nor do you specifically need to define them in your openser.cfgs (i.e. listen=external IP). You only need this if you are in a non-NATed environment, so it's a case of either or.
Hope that made sense.

Hello All. I'm trying to install 2 Instances of openser on the same machine with the following interfaces:
Instance #1 -----> 172.16.18.2 and 192.168.1.112 Instance #2 -----> 172.16.1.2 and 192.168.1.113
I made one installation on the default OpenSER folders and one in the /usr/loca/openser_1/
The configuration went quite smooth. The first instance of the server is running with no problem at all, but when I try to start the second instance I got an error that it was unable to resolve the IP addresses I add the following lines to the /etc/hosts file:
### OpenSER 1st interface configuration #### 192.168.1.112 openser1_internal 172.16.18.2 openser1_external ### OpenSER 1st Interface configuration ####
### OpenSER 2nd Interface configuration #### 192.168.1.113 openser1_internal 172.16.1.2 openser1_external ### OpenSER 2nd Interface configuration ####
After that Now I have the following error:
Jan 5 17:26:30 atel-router ./openser[17772]: ERROR: tcp_init: bind(7, 0x813e194, 16) on 192.168.1.112:5060 : Address already in use
Any Help will be appreciated, of better is there a How-to on OpenSER multiple instances please let me know.
Thanks in advance
