Ubuntu Security :: How Does Network File Sharing Work
Jul 29, 2010
How does network file sharing work in Ubuntu? Is it only enabled for the Public folder? Or does it vary by folder permission settings, specifically in that folder's 'Properties' and allow others access the folders?
I'm asking because someone at my work may have had a complete breach of their personal files in the /home/ directory from their folder permission settings. I want to know if regardless of everyone having access permission to the folder, if they need to drag it to the Public folder for it to be network shared.

I am pretty frustrated with Ubuntu security partially because I don't know exactly how to fix things in it like I do windows and you can't always use GUI with Ubuntu which is quite annoying. Basically.. I created a samba share. When I copy files from my Windows machine TO the Samba share the permissions are always screwed up. I can watch the videos but I can't delete them. I have to go into Nautalis? via F2, sudo something and change permissions everytime I copy something into the shared folder. To me, this is stupid.
Another issue... I added a 2nd hard drive to my Ubuntu machine, shared the entire drive. Once again.. when I copy files to the share I can only read them.. I have to keep stealing ownership so to speak over the files. Now, when I want to CUT and PASTE from my Drive "C" Ubuntu to my Drive "D" I dont have access. Ugh... why can't there just be a way to make all files accessable.
Why should I have to pop into a different program to regain permissions everytime. When I create a folder it should STAY that way. Anything I copy into it.. its MINE. Just because I copy from another machine onto THIS machine, I am still the creator of that folder. I SHOULD have access to EVERYTHING in it.

I know that this is easy, but I am confused.I have three computers all with a clean install of SUSE 11.2. Two of them use wifi with the internet and the third is wired.I would like to share files between them all of them.When I go to dolphin/network there is nothing there and I don't know how to set it up.

I just installed suse on this computer, and am wanting to allow other computers to store files on it as a file server. I was reading the online manual and in the personal file preferences, it shows an option to enable 'share public files over network'. The problem is I don't see that option when I open up file preferences. All I see is an option to allow sharing using bluetooth, nothing about sharing over the network. When I look in the network I can see the computer running suse, but when I try to connect to it, it says 'unable to mount drive: connection refused by server.'

Should I uninstall dnsmasq?I've already removed it from chkconfig:> chkconfig --del dnsmasq

Ok Ive tried soooo many tutorials and been through sooo many forums but I cant get my file sharing to work from any computer. Ive got a - Ubuntu 10.04(64bit) desktop to use as a home web/file server, wired.(BEN-SERVER)- Vista(32bit) laptop, wireless.(BEN-LAPTOP)- Windows 7(64bit) desktop, wireless.(BEN-LAVIE)- EchoLife HG520s ADSL2 wireless modem.
At the moment...In Ubuntu network browswer it only displays BEN-LAPTOP.But trying to browse BEN-LAPTOP I get "Unable to mount location Failed to retrieve share list from server".Vista only displays BEN-LAVIE and browsing gives me "Windows cannot access \BEN-LAVIE"And Windows 7 doesn't display any.Previously I was able to share between Windows 7 and Ubuntu but I don't know what I did but it stopped working. I have since reinstalled Ubuntu and tried again from scratch but no luck

For the first time networking my home computers I'm not interested in getting Ubuntu boxes to to talk to Windows and we now have Ubuntu on all machines.
I'm trying to use the "Personal Files Sharing Preferences" but there is a message telling me I require some packages. Most unlike Ubuntu but it doesn't tell me what packages I do need.

What I would really like to do is have access to sertain directory's on other computers and have full access to read/write within the home directory.

have a home network with two desktops and I also have a netbook. The netbook and nettop (desktop) both run UNR 9.10 and my other desktop runs Ubuntu 9.10 with all updates in place. So all 3 machines are hooked up to my home network via wireless router (secure and password protect). I want to set up file shares between machines in order to move files between machines and also to have all machines connected to and accessing one shared printer. Fair enough. According to Ubuntu help I click on a folder, then properties then the share tab and click all checkboxes and give the share a name. Then I do likewise on my two other machines. So in theory once every machine has a share setup then you should be able to access via the other machines by simply going into Network, finding the machine, opening it and mounting the shared folder. In some cases I see the other machines but when I click to open them it says "unable to mount location". So now I would like to ask... where should I look to resolve this? The wireless router settings? Some type of network or security settings on each of my machines?

I'm using 10.04 beta...
If I go to system - preferences - personal file sharing, I cannot select "share files over the network." The panel is greyed out and the message "This feature cannot be enabled because the required packages are not installed on your computer" is shown
It ever so usefully doesn't tell me what those packages are though! - It'd be nice to have more useful error messages or the ability to click to install them...
Anyway, what do I have to do to get this going again?! I've installed everything to do with samba, webdav that I can find but still no cigar...

I want to share files between my desktop box and my laptop either by my mains-LAN or by ethernet cable and cannot find anything on the forum to point me in the right direction. There is plenty of information to help with the installation of Apache/LAMP and the like. But is this what I need? Will I need to create logon IDs to the desktop to share files (and even the printer?).

I'm having issues setting up file sharing between two Linux machines. I've tried the forum cookie cutter answer of "right click folder, sharing options, share, allow others to write and edit, allow guest accounts", but I simply cannot get my two Ubuntu 10.10 machines to see each others shared files. I HAVE been able to download and use the program "Personal File Sharing", and with it I CAN share the "Shared" folder between both machines. I'd prefer to learn the correct way to link these two boxes up though, and be able to share more than 1 directory. Am I missing any programs to complete this link? Do I need to use Samba? I've tinkered with it, and I can get both computers to see a workgroup name I set up, but cannot get them to view each other in it.

I'm going to setup a File and Printer Sharing in my little home network... 3 Computers actively connected to the Web through a single ADSL2+ Wireless Router (number of Computers will increase later) At the moment 2 of the computers are running Fedora 10 and 1 running Windows XP...
Now i want to setup the 3 machines to use 1 printer which is connected to one of the Fedora 10 machines, and i want File Sharing to be enabled so each machine can easily view each others shared files and also be able to print when ever needed (ofcourse the machine with the printer will have to be on for the printing process to happen) I've installed Samaba on each Fedora Machine, enabled sharing but i dont seem to be able to view the Windows machine or each other....

I have a wired lan at home with 2 XP boxes connecting to a router to a DSL modem. I want to network my laptop, running only fedora os, for file sharing, printing and internet access. I will be using the laptop probably exclusively for creating/maintaining a Drupal-based (LAMP) e-commerce site to replace our old one for our small family business.

I want to learn how to build a Linux network from scratch that includes file and printer sharing, intranet. I have an intermediate-level knowledge of Windows networking. Can anyone suggest a book or online tutorial that I can learn from? Now let me be clear: I am finding no shortage of tutorials on the web. However, too many are old or incomplete.
A little extra info: I am a teacher/network admin for a small private school with about 50 student computers (that I wish to become Linux machines in the future) and about 10 staff computers (mostly Windows laptops--I do not expect the staff to convert to Linux as readily), I currently do not have an intranet implemented.

I set up a samba file sharing system but my workgroup asks for a username and password see this-This is the text in /etc/samba/smb.conf:
# smb.conf is the main Samba configuration file. You find a full commented
# version at /usr/share/doc/packages/samba/examples/smb.conf.SUSE if the
# samba-doc package is installed.

A couple of weeks ago I was using openvpn with a provider of PVNs on a home wifi network with no problems.I had installed openvpn using apt-get install and downloaded theopvn PVN files from the organization.erything worked fine.I would type sudo openvpn nameoffile.ovpn and then add my username and password during the installation process.However, when I try to do the same on an Ethernet network, the installation work fines (as above) and informs me that everything is connected (same as on the home Wifi network) but Firefox and all other software cannot connect to anything on the Internet.I contacted the organization who said the DNS was a problem and I needed to install resolvconf then modify each .opvn file using up /etc/openvpn/update-resolv-conf and down /etc/openvpn/update-resolv-confcauses the installation to hang because it does not like openvpn pointing to an external file.Irrespective of the problem I have with this "solution", previously I could use openvpn without modifying the .ovpn files. It just worked! I wonder if anyone knows why using the exact same configuration on an Ethernet network (which I have not used before with openvpn) is causing problems

I want to use samba for file sharing like on a Windows home network. Actually they are all Linux machines but nfs is too complicated. On my host machine I installed samba and system-config-samba. I created a new share for /home, check marked writable and visible and put access to everybody. For preferences-->server settings--> security the "authentication mode" is set to user, encrypt passwords is no, and guest account is no guest account. Under preferences-->samba users I added myself as a user with the same windows user name as my Linux user name and the same password.
My client is a virtualbox fedora (used for testing purposes but actual clients will be real computers on my home network). I entered the address smb://192.168.1.184. When asked for the user name and password I put my regular user name and password since that was what I set in samba users. However, the password dialog keeps coming up and won't let met into my own computer. If I quit it says something like access is denied. How can I get my home network back? I liked this feature when my home computers ran XP but I switched them to Fedora 12.

how efficient and effective are these snort, argus, ossec etc etc for an organization having 3500 PC Network, connected through 700+ Cisco Devices (Layer 2 and Layer 3), and scattered on 130 different sites (geographically)? what should be the combination of products and what should be the architecture for an efficient forensics activity?

I have two Suse un-firewalled computers connected via NFS. About a year ago I found instructions for a very SIMPLE way to share a CUPS connected printer using Yast. When I installed 11.4 I lost the instructions. It required no config file editing and took about two minutes. Google searches focus on complicated SMB-Linux connections like those suggested by swerdna.

I have several Proxy severs set up at our business. I always do the same basic config, except for my version of Fedora (I always grab the newest).
I put 2 nics in a machine Load Squid, Dansguardian and Firestarter. I use Firestarter to direct the surfing traffic from my LAN out a cable modem that I have for each store. This lessons the bandwidth on the T1.
Easy enough. My problem is Firestarter has always been a little flaky. But as of F11 the gui wont stay up for more than a few minutes at a time. It still functions, but you have to be quick if your going to use it because it will inevitable crash.
So I suppose it's time to start doing this the correct way and using IP Tables. Does anybody have a resource they can point me to that will help me understand how to do this? It looks like this might be as simple as setting it up with the GUI Firewall tool that comes with F12 but I'm still not exactly sure how.

I have have recently installed Ubuntu 10.04 on my desktop pc and set-up a shared folder and a shared printer from the Ubuntu desktop. My shared folder works completely fine and is easily accessible by my windows xp laptop. My printer sharing initially worked fine and I was able to connect and print from the windows xp laptop. Unfortunately, after a reboot of the ubuntu computer the printer is no longer found by the laptop (the shared folder, however, still works fine).
I can get the shared printer working again by using the following command to restart Samba: -
sudo service smbd restart
After restarting Samba, suddenly my laptop can see the printer again. I don't particularly want to have to restart Samba every time I boot up my computer. I understand I could probably make a script that would restart Samba automatically after booting or logging in, but I would rather fix the actual problem than use a workaround like that.

I am using 10.4 desktop and currently got everything setup the way i like it, but when sharing my network folder I can see the folders and everything seems fine then when i click to access the files it gives me an error message of not having permission to the folders. I tried going into the basic permissions tab in folder properties like you normally would with ntfs permission sharing in windows (don't know if thats how things work in Ubuntu but i gave it a try) and nothing would change when trying to change read/write permissions or read only permissions.
