I can only access the web server and connect to shh. After a reboot some of the services are blocked. I have a web server, a samba server, a game server and a ssh server set up.Įverything used to work fine, until I did something that I'm not sure what. This can be mounted as a network drive easily on Linux, Windows, and Mac boxes.I'm a relatively inexperienced Linux user and I'm having issues with connections to my machine. The user should be encouraged to change this password remotely as follows: smbpasswd -r server.domain -U Using the shareįinally, with the given configuration, access to the share is through the following service name: //server.domain/share Use the same password both times and communicate this securely to each user. Note that you’ll be asked to enter a password (and verify it) twice – once for the system account, and once for Samba. adduser -home /opt/share -no-create-home -shell /usr/sbin/nologin -ingroup sambashare ![]() ![]() The following commands do the trick, making sure each account is with the sambashare group. Now test the configuration file with ‘testparm’, if everything is ok, just reload samba service: sudo service smbd reload Manage user accounts for co-workersįor each co-worker I needed to create a system user account (but one without login access) and enable this with Samba. Here we set them all the same so that all new files and folders get group read/write access this makes sure all of us using this share can access the files anyone else creates. Valid users = that there are two sets of masks create and directory masks give maximum priviliges (AND), while the force create/directory mode give minimum privileges (OR). To create the share, just add the following to the end of the file: The default configuration (in /etc/samba/smb.conf) works well for most purposes, but one would probably want to update the workgroup at least. If your organization maintains internal firewalls (mine does), you’ll need to request the relevant ports to be opened accordingly. This should directly allow other users access to your machine if they’re on the same subnet, but things can get hairy if they’re not. For UFW this is done with: ufw allow Samba If you have a firewall on the machine make sure you set it up to accept incoming traffic on the Samba ports. sudo apt-get install samba Firewall setup On Ubuntu this is simply a matter of installing the relevant package, as shown below. Setup is rather straight-forward, as follows. the SMB/CIFS protocol, as used in Windows shares). To keep things simple, I have decided to use Samba (i.e. ![]() That is, only specific colleagues should be able to access it, with individual credentials. However, I don’t want to make the folder publicly accessible on the network. This is my personal desktop machine, so only I can login (whether on the console or via SSH), and I don’t want that to change. I want to share a folder (/opt/share) on my workstation (server.domain) with co-workers, so they get read access to everything and write access in a particular sub-folder. Perhaps it will also be of use to someone else. However, a concise version for my own reference is useful. All the information here is available elsewhere on the internet, notably in this post by Elliot Cooper. Today’s tech post is a bit of a note to self.
