Acces a file server(hnas) behind a firewall from compute server - which port

[tlk]

Hi,

I need to access files that are behind a firewall from my compute server(sasapp) which port do I need open to do this.   IT dept is asking me which port to open, they won't open all the port, I browsed the documentation but didin't find anything on this.

Anybody have an idea ?

Thank!

Laurent

@tlk ,

I assume you will be accessing those files via NFS? If yes, then read the following NFS security guide: http://tldp.org/HOWTO/NFS-HOWTO/security.html. Your Linux administrator can help you with that.

Thanks, I will look at it with IT dept, I have to mention that my compute server(SASApp) is on Windows.

Thanks, I will keep you posted

It doesn't really matter what OS you are on. Either way, you have to mount the NFS disk on the compute server.

If you want to refer to your remote file server with a UNC path like \\MyFileServer\MyFileServerFolder1\MyFileServerFolder2 then you may need to configure Kerberos settings. This is something your IT department and / or SAS administrator should be familiar with.

Thanks,  That's exactly what I want to achieve,  I want to acces via unc path.  This morning  I asked to add the file server to the delegation.  Kerberos is already configured to acces other file servers that are not behind that firewall.

Kerberos is configured and the delegation on the file server is active. Stil I have I/O error when I attemp a Libname. So I return to the inital question which port SAS compute server(SASApp) uses to access a file server, I will have them open on the firewall.

Thanks!

Interesting IT-department. If you say, that you need to access files via unc-path, they MUST know which port to open. It should be port 445.

SAS uses the operating system to access files. It does not care if files are stored locally or on a network share.

The port(s) used to access a network share depends on the protocol being used (SMB, NFS, ...).

So you have to leave this to the system and network administrators, they will be able to determine which protocol is being used, and therefore what ports must be opened on the firewall.

I suggest you log on to the SAS server outside of SAS (via SSH) and determine from the commandline if the network share is accessible at all.
