What version of CMS are you running? v1.0 or current master branch? Do you have a config file installed? Is CMS able to read it? Note that by default the file is installed in /usr/local/etc/cms.conf owned by cmsuser:cmsuser. If you start CMS with an user that doesn't belong to the cmsuser group that file won't be readable. Does AdminWebServer print a line like "Using configuration file ..." when it's started? Documentation reference: [1] and [2]. [1] https://cms.readthedocs.org/en/v1.0/Installation.html#installing-cms [2] https://cms.readthedocs.org/en/v1.0/Running%20CMS.html#configuring-cms If that's all right but AdminWebServer still doesn't start then there's probably something wrong with your configuration file or with your network interfaces. Please report to us for further investigation. On Sat, Jul 27, 2013 at 7:50 AM, Hamed Valizadeh <havaliza@xxxxxxxxx> wrote: > I tried running CMS on two machines with Ubuntu 12.04.
