Hi All, We are using Amazon EC2 linux wheezy (64 bit) instance for running koha 3.16.01, We are running Sip2 server now although we changed the line (port="127.0.0.1:6001/tcp") to our amazon private ip like this (port="10.106.151.178:6001/tcp") but when trying to logging by telnet the log file also gets us this error Bad arg length for Socket::unpack_sockaddr_in, length is 28, should be 16 at /usr/share/koha/lib/C4/SIP/Socket.pm line 830. Although, the desired ports are opened and there's no any typo. thanks
