socket problem

Hi to all, In order to execute two bsc_hack at the same time i have changed port for oml link from nv_put_oml() function in ipaccess_config.c and i also changed oml port from ipaccess.h . When i configure nanoBTS with ipaccess_config i can establish two different oml link between two bsc_hack and two nanoBTS. rslHowever, they can not establish link at the same time. I could not find where can i change rsl port of nanoBTS. I have searched the wiki and i could not find a nanoBTS message to change the port specified for rsl link. Could anyone give me some information about this? Thanks. Jason
