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 ####


I guess you should rename it openser2_internal
                                    ^


and make sure that openser2 does use the proper config (use -f to 
specify the config file)

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
