Hi, I have installed ser-0.8.11 on my redhat linux 7.3. SER is running fine. To check whether my server is responding to requests, i installed sipsack. My SIP_DOMAIN= "myserver.foobar.com". On giving command sipsak -T -s sip:admin at myserver.foobar.com. It shows following error. "no gethostbyname: No such file or directory" Regards Prince Arora
