Ubuntu :: Can't Find Samba Host With Some Users
Apr 3, 2011
If I try to connect to my Samba server with one user ("alex"), everything works fine. If I try to connect with a different user, ("guest"), I receive the error:
Code:
Retrying with upper case share name
mount error(6): No such device or address
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
Both users have been added as samba users using `smbpasswd -a`
These are the settings I've added in my smb.conf file:

If I want to add Windows & Mac users as Samba users, must I first add them all as Ubuntu users? If so, since none of the other users will actually be working on the Ubuntu Server, how do I disable the other non-admin users on the Ubuntu Server login screen. I am using Webmin to administer some server settings, and command line for others.

I work as an system administrator for AIX and Linux servers. We have an FTP server running in Linux which has shared folders to Windows domain using Samba. The new requirement is to map users created to Linux machine to Windows users in such a way that, when a user logins into Windows machine with an ID say "X123" in domain "TEST", his access control to the samba shares should reflect based on the same user ID created in Linux machine.(FYI. Both the Windows and LINUX machines are in same network and domain). Please let me know the step by step procedure to configure Linux machine (smb.conf entries or any new file to be created for user mapping) to identify Windows user Login and provide access restrictions accordingly.

I got a bunch of machines (~10) that I share with my co-workers. I have appropriate .ssh file(s) set up so I don't get prompt for password when I try to ssh.Currently I ssh into these hosts and then do a top to check the load before I start using the machine. Because I don't want to be on a busy host.Can someone show me how to write a script that find a least-busy host given a list of hosts to check? (hardcoded is fine)

I've installed VirtualBox OSE and have a couple of guest OS setup. I am running Ubuntu 11.04 and VBOSE version 4.x (the most current). Now this installs the guest OS virtual harddrives to a folder in my home directory. How do I get other users on the same host machine access to those virtual machines within VB? Currently logging in as another user and going to Applications/Accessories/VirtualBox OSE ... the list of guest machines is empty save of course on my login.

I am wondering how websites like banks are able to determine if you have previously used a certain computer to access the website, even if your router's IP address may have changed and your system's cookies have been cleared. I have users that need to access our HTTP intranet from outside locations. Those locations will have dynamic IP addresses most of the time, so I can't just "allow from [ip]" in my Apache proxy configuration. Originally we considered a VPN, but determined that a VPN will be overkill to access just an internal website, since we do not want external users to have permission to the rest of the network, only the website.I currently have it working over HTTPS with basic authentication against an internal LDAP server, but I want a little more security for such an important website.
crappy diagram:
[user]-->(internet via https)-->[apache gateway]-->(intranet)-->[http server]

I'm setting up a LAMP production server for the first time. When I installed Ubuntu server edition, I selected to install Samba. My idea was to be able to easily access the server's files on the LAN using Windows. All was well and I could ping/ssh between Windows and the Ubuntu server without any problems using the host names. Later, I became concerned that running Samba on a production server might introduce security issues. Therefore, I used apt to purge Samba.
Now I am unable to ping/ssh between the Windows machines and the server using the host names. It only works if I use the IP address.
Two questions:
1.) Is it a security risk to run Samba on a production LAMP server?
2.) How do I get back to being able to use host names without installing Samba?

I have two ubuntu 10.04 64-bit servers running samba (3.4.7) and openLDAP (2.4.21). The LDAP directory is successfully replicating between the two servers. These servers also serve as LDAP servers for sudo, pam, nss, and other services for a dozen servers without issues. The BDC samba is configured to use itself for LDAP. I connected to the BDC using the samba ldap credentials and verified I could a) see the Computer object b) read NTPassword and LMPassword. The workstations can authenticate to the domain successfully against the PDC. If a workstation boots and connects to the BDC, they login fails with:
Code:

All I want is a simple Samba installation that anonymous users/guests can access. I have modified the smb.conf file so much using 'tips' that should enable a simple folder share. Nothing works. If I share the folder using Nautilus share then the folder is accessible without any credentials from only Win7 and android ES File Explorer. XP can't see the folder, nor can any other linux device. I want to switch to linux as a main OS but without shares it's not practical. Does anyone have a stripped down smb.conf which provides guest access to a single folder?
Here's the latest testparm -s

I am having a problem with Ubuntu 10.04. I was setting up network sharing with Samba. Set up went fine, then I decided to change the hostname.
Following instructions I found on the web, I edited etc/samba/samba.conf to reflect my desired hostname.
Now I have to use superuser to run synaptic or update center. I don't know what else I have "broken".
I would like to change my hostname, if I did it incorrectly for 10.04 please enlighten me.

I'm not sure if this is even possible and I've tired searching, but I can't seem to figure it out. I have a few shares setup in Samba. I want them to prompt for a username and password. If an invalid user/pass is entered I want the user to be authenticated as a guest.

I've set up smbd 3.4.7 on 10.04x64 LTS server. I've set up a couple shares and I'm having problems blocking access to certain directories using native file permissions. There is one directory that has folders for each sales rep to store their current list of quoted clients, I only want sales people to be able to browse the directories owned by themselves. Everything seems to be set up correctly in terms of user groups and permissions on the filesystem.
Below is marina, a sales rep, and brian, a super user of sorts.
id marina:
Code:
uid=1011(marina) gid=1006(office) groups=1006(office),1005(sales)
id nick:
Code:
uid=1000(brian) gid=1006(office) groups=1006(office),118(admin),1001(full),1002(processing),1003(management),1004(it),1005(sales)
Below is the directory with all the sales reps folders.
ls -la:
Code:
total 60
drwxrwxr-x 15 root it 4096 2011-02-10 20:06 .
drwxr-x--- 9 root office 4096 2010-11-19 12:40 ..
drwxrwx--- 13 katya full 4096 2010-12-07 12:36 Katya
drwxrwx--- 18 lana full 4096 2011-02-08 17:09 Lana
drwxrwx--- 23 marina full 4096 2011-02-10 18:09 Marina
drwxrwx--- 4 mike full 4096 2011-02-01 12:42 Mike
With this setup marina only be able to browse her folder, but she can browse all folders and has full write access to all folders. This leads me to believe something is up with the smbd.conf file, which is below.
Code:
[global]
workgroup = COMTREAD
null passwords = no
server string = Root Server
dns proxy = no
log file = /var/log/samba/log.%m
max log size = 1000
syslog = 0 .....
In this case the valid users directive would not work cause I am not making a share for each user. I had this on other shares like the db2 share. My windows box lagged heavily when I tried to access that share with an invalid user. How to deny users the ability to modify permissions I would also like to do that.

I have a Samba server running on a Red Hat 5.6 system that provides a large file share to both UNIX/Linux and Windows environments. There are two user accounts that can access this file share:
foo - has full access to ALL files in the file share
bar - has full access to just one directory tree ('dog') in the file share
I created two different mount points, one for foo and one for bar. I've set all of the files in 'dog' to be owned by bar, which works fine for the bar account. The problem is, the foo account can't access the files. Also, foo and bar need to be able to share files, by placing them in the 'dog' directory tree.
I'm not sure how to set this up using standard Samba tools. I've looked in the Samba GUI available with Red Hat, and don't see anything helpful there regarding my need. I've Google'd and have seen references to using ACLs with Samba. Is this the right solution to this problem, or have I missed something?

We have an existing Windows 2000 network that I am trying to add an Ubuntu 8.04 server to. I have put links into the windows domain DFS to the linux machine's samba shares.
The shares work fine for local users that are physically on the same network (192.168.0.X). Remote users from other offices or dialing in with a vpn client can not access the these particular folders off the DFS. However, they can map them directly from the ubuntu server.

In my ongoing hunt for a Samba GUI that is feature packed, well supported, easy to use, yet doesn't suck, I found myself tinkering with eBox. I have it installed and fired up but I'm a little confused. I can add a Samba share - okay great. But I sorta need to add users. Where on earth can I add users? The users and group section of eBox doesn't appear to be related to what I need, and I also cannot get into the access control section of the very share I just created.

I would like to share a folder from a Linux Guest with a Windows host (with read and write access if possible) in VirtualBox. I read in these two links: here and here that it's possible to do this using Samba, but I am a little bit lost and need more information on how to proceed.
So far, I managed to set up two network adapters (one NAT and one host-only) and to install Samba on the Linux guest, but I have the following questions now: What do I need to type in samba.conf to share a folder from the Linux guest? (the tutorial provided in one of the links above only explains how to share home directories) Are there any Samba commands that I need to run on the guest to enable sharing? How do I make sure that these folders are only available to the host OS and not on the Internet? Once the Linux guest is setup, how do I access each of the individual shared folders from the Windows host? I read that I need to mount a drive on Windows to do this, but do I use Samba logins, or Linux logins, also do I use localhost? or do I need to set up an IP for this?

I have found a tutorial in the How-Tos on this site but I'm not sure if they are exact and I'm paranoid about messing something up. The link to the tutorial is below. Is there anything that I should do different or anything that I should be aware of? Also, once this is set up, how do I transfer files between the two machines?
