[Users] Re: [openser] fail to listen on two addresses

[Jeremie Le Hen]

Hi,

I didn't use to reply to my self, by I eventually understood what was
going wrong and I wish to post it for the record.

Actually, using the -D flag -- which prevents OpenSER from forking --,
prevents from listening on more than one IP address.

I think this ought to be noted in the manpage.

Sorry for the noise.
Regards,
