Hi,

The CIFS and FTP servers use ports below 1024 so you need to run the server under a privileged account.

It's possible to change the FTP server port to use an unprivileged socket number but CIFS requires particular port numbers to work correctly.

Cheers

Gary

Hi Gary … running the Alfresco server as su worked a treat. Also I stopped the samba service ….. assuming that Alfresco starts it.

Now I get this error reported in the alfresco.log file

Hi,

Try changing the <broadcast> setting in the file-servers.xml to match your network settings, the default settings use the 255.255.255.255 broadcast address which doesn't work on some networks.

Why is that? Alfresco doesn't run when we change the broadcast mask from 255.255.255.255 to the broadcast mask of the compmany. It works with the deault (and for our company worng) settings. Any idea?

Update: I think we fixed it, probably some wrong broadcast address, sorry to bother you guys.

Hi Simon,

Could you email me the output from an ipconfig command on Windows, or ifconfig on linux and also send me the file-servers.xml you're using (with the updated broadcast mask).

Thanks

Gary

Hi,

You'll need to run Tomcat/JBoss from a privileged account under linux/Mac OSX/Solaris as the CIFS server uses privileged ports (137/138/139/445).

You can either use root or setup a less privileged account with the required privileges only.

Cheers

Gary

Still cannot get it, right now I just run it on Centos Linux, and as root, work well, but i dont like this privilage, root .

i want under frans, but still new in CIFS world.

do you know how to setup the less priviage in linux?

and how can i know that the CIFS server run well?

i use the server on the net you can see at http://www.blueoxygen.org:8080/alfresco

i use the jboss bundle, and run on root.

Hi,

After some investigation it looks like you may have to run as root if you want the CIFS server enabled under linux.

To check if the CIFS server is running first check the alfresco.log log file, there should be some entries for [alfresco.smb.protocol]. Then try and connect to the CIFS server from a Windows PC using Start->Run and enter \\<servername>. The Alfresco CIFS server name defaults to the name of the system it is running on with _A appended to the name, so if the server name is CENTOS the Alfresco CIFS server is CENTOS_A.

Cheers

Gary

After some investigation it looks like you may have to run as root if you want the CIFS server enabled under linux.

We are interested in this as well. Isn't it possible to run Tomcat (or JBoss) as root and Alfresco as, let's see, Alfresco user?

I found this in the WIKI on the Troublehooting page:

The SMB/CIFS server uses ports 137, 138 and 139, the FTP server defaults to using port 21. All of these ports are in the privileged socket range so require that Tomcat or JBoss be run from a privileged account.

Don't know if my assumption is correct but isn't it Tomcat that opens the required port(s) for SMB/CIFS? If this is correct then Tomcat should be able to open a port when I run it as root and Alfresco (which is just a webapp) could request the port even if it isn't run as a root user.

Does this make any sense?
