Ubuntu / Apple :: Establish Server For 45 Users With Appropriate Permissions
Nov 18, 2010
I've been living a dormitory for a while and our net connection is very slow because of the download via torrent or rapidshare, hotfile etc.(we have 4megabit speed unfortunately) I want to establish a ubuntu server and there are 45 people in our dormitory. Which ubuntu server version I'll use? How much storage that I have (i thought 4 tb is enough)? What kind of commands do I going to use and permissions. I want to appoint one person as a admin others just can add a file (music, movies vs.) they wouldnt have to delete!

I just finished installing Lucid Lynx on an iMac7,1. I would like to still be able to access my Mac Documents directory from within Ubuntu, so I can have a common directory that both systems can access. Right now, however, I am unable to do that. It looks like it might be a permissions issue- ie I am a different 'user' on both systems, so I don't have access to my Mac files. Is there a way to have the same 'user' account for both systems? If not, could a common 'group' be created in both systems that both of my 'user' accounts have access to?

I am trying to deploy Kerberos and LDAP so users will be able to login in to a server on the edge of the LAN, and afterwards be able to establish a SSH connection to all the computers in that LAN without the need to type any passwords, and without the need for me to manage SSH keys [beside the SSH keys on the login server] and local user accounts.
1. When i create the users in OpenLDAP i use a template that i created by reading documentation from the Internet. In the template one piece of information that is neede is the UID. Is there any clever way the keep track of the numbers so i do not assign the same UID to two users, besides using a pen and paper?
2. For the users to be able to establish SSH connections between the computers, the host is going to be added to the keytab like this: ktadd host/client.example.com Is is possible to replace client with something genric so i do not need to mange these keytab files between the hosts?
3. Users will be logging on the the server on the edge of LAN by using SSH keys. How can i configure the setup so the users will recieve a ticket automatically when the logon without executing kinit and without entering a password, just by having a valid SSH key?
4. krb5kdc is running on all the network interfaces in the server i want it to only run on eth1, how can this be done?

Having set up many windows servers with complex permissions on shared folders, I now have to do the same in Linux (and I'm such a noob to Linux) I understand that each file/folder is assigned a user + group, and that the rights can be set for the user, the group and global (aka everybody else) My challenge is this, inside my shared folder there is a folder that should be RW to some users, READ ONLY to others, and not accessible at all to the rest of the users. (lets call the folder MyFolder ) All 3 groups have more than 1 user, so they have to be groups (right?) How would this model work in Linux ? If there is no other way, I guess I can nest the MyFolder in a folder that has permissions to allow all users that may access MyFolder, and block the rest, then on MyFolder, set owner group the RW users, and set global to READ ONLY.
Ps : The server I'm setting up runs Debian Lenny, files will be accessed from windows workstations using samba.

I am trying to establish an ssh connection to my server. I have a regular ssh connection working through the command line, so I know my key works and I have the port forwarding on the router correct.
When I go to Places -> Connect to Server the window comes up properly. The only problem is that the drop down menu only has one option in it for Service Type. It is Custom Location. I have had this set up in the past and there were other options there. I chose the ssh connection and everything was fine. Now it doesn't work.
I have tried to completely uninstall nautilus and reinstall it, but that didn't work. When I did uninstall it, I uninstalled gnome-session as well, and I reinstalled that one too.

I installed ubuntu on a G3 iBook using this guide: [URL] (because its a slow a** laptop).
I'm almost certain that it never ever prompted me to set up a username or password. I'm almost certain because I've installed linux on a good number of different systems and I use the same exact username and password every time.
But I was kind of shocked when it prompted me for a login and password and I'm thinking to myself "uhhhhh.... I didn't set up a user yet...". So I tried my usual login and nope... "Login incorrect". I can't do anything because I'm not logged in... and I can't use recovery mode either because its PPC or because its a Mac so there is no GRUB.

I've been a Linux user for some time. I was originally a Debian user & had switched from Debian to Ubuntu around Breezy Badger. I recently acquired a PowerBook G4, Its an amazing machine and I can see why Apple users are Apple users. Its been alot of fun familiarizing myself with OSX but I dual booted with the latest release of Ubuntu so I could also feel at home. After installing Ubuntu 10.10 I started installing software, I couldnt find appmenu-gtk anywhere. So I searched google for about an hour to find no answers.
So is it that appmenu is not available for PPC edition of Ubuntu? Why is this? & Will we ever see it for PPC?
If this is the case, what other software isnt available for PPC?

I installed ubuntu on my MacBook Pro, and now I get the infamous "still waiting for root device" when booting mac os x. I couldn't find any solutions that worked (macbook pros don't have a BIOS, or any drives that are easily removable). Anyway, so I have ubuntu working, and I need some files from OS X before I would consider reinstalling, etc. So I mounted the drive, went to users, etc. and it says that "I don't have the permissions necessary to view the contents of ****".
I did chmod 777 /media/os x/Users/* but that led to "Could not access: No such file or directory" (there's a space between os and x, I think it counts it as two commands or something and I can't rename the drive). Any way to give myself the permissions to access my files, or maybe just to copy over the whole hard drive to my main computer, or maybe somehow solve the "still waiting for root device".

So I'm trying to put together a birthday present for my girlfriend. Here's the background. She just got back from a semester abroad in Rome. She's having a hard time getting used to living in the states again, so I want to make her a photo album with all of her pictures from Italy and the rest of Europe. Its a surprise, so I can't just get them from her. I've got her Time Machine, which has all the photos on it (I'm 'debugging' it for her, she's not so tech savvy). I've found the pictures folder, but I don't have the permissions to access it.
So the question is, I have her username and password, what do I have to do in order to read the file with all the pictures in it? I'm not a crazy stalker, in case you were wondering, I just don't know how to change my username to one that have permissions for the folder.

I recently upgraded my flavor (Arch, latest version) and now I am unable to connect to samba (latest version; obtained through pacman) either through Windows or Linux. My error logs reveal: (/var/log/samba/log.smbd)
[code]....
nmblookup shows what it should but smbclient -L gives the generic "Error NT_STATUS_UNSUCCESSFUL". I also tried to reinstall Samba. I am not sure why it continues to try for CUPS, as I do not have printers listed in smb.conf.

I recently installed 10.10 on a Mac Powerbook G4. Everything seems to be working ok, except I cannot access the Users and Groups. If I try to launch it from the terminal I get the following error: "Glib-GIO-ERROR **: Settings schema 'org.gnome.system-tools.users' is not installed"
This is a clean install, with no changes made to the system. I then ran all the waiting updates and am still experiencing this problem.

Working in CentOS. Want to have drag-and-drop SCP access to another system.
Opened up the file manager (nautilus) and went under File -> "Connect to Server". Filed in the information, hit connect. The connection will sit forever and will never properly establish. It creates an icon on my desktop, but noting else.
If I go into terminal, su to root, open nautilus and then repeat the process as a root user, then it works successfully. Connection established after I trust the remote host. File transfer works fine.
what is occurring when I attempt to connect as my normal user?

I was just trying to add new ssh users for tonight session and really messed up badly. I first installed package ibsh (iron-bars shell). I didn't know how to use it so I just went to a new user account and added ibsh at the end of his .profile. (I wrote
Code:
sudo gedit /home/username/.profile
which I suspect is the problem, I should have written
Code:
gksu gedit /home/username/.profile
??)
Well graphical logging became impossible in my own account until I did the following in my own account:
Code:
chmod 777 .profile
chmod 777 .ICEauthority
But desktop is still empty. I have restarted the system. I cannot use Firefox (it works without output for 10 sec and then dies). Chromium says something like "Problems due to not being able to update profile" but works. (I cannot see any files on desktop. But if I do places > desktop I can see them.) All the mentioned files had -------- for permissions so I did:
Code:
chmod 777 ~/Desktop/*
How to get my system back to normal. I think I got botched up permissions. If I create new user accounts, I get several error messages in these accounts.

I'm building a small web gui to connect a 3g modem with wvdial via web interface using perl cgi. Which permissions I should use. Now when doing "wvdial 3gconnect" from the perl script it don't have permission to do anything, reading config files, accessing the modem etc.
Its just a little raspberry with only 1 user not available from the internet so its not a problem with loose security. Is there some easy way to let the www-data user get system wide permission without setting the permissions on each thing it should access?

I need to assign permissions for ftp users. For that I need to create groups with different permissions like upload, download, rename, delete, rename and delete. And the users added to the group need to have that group permissions by default.

I've had Dovecot up and running for months now without any problems whatsoever. Came in this morning and suddenly I can't connect to it. Thunderbird hangs with "Checking mail server capabilities..." and Windows Mail spits out the following error:
Code:
Cannot establish TLS with IMAP server 10.0.0.2:143, SSL_connect error 336142597
Configuration:
Account: Blah
Server: foo
User name: whatever
[code]....
Thing is, I'm not using TLS/SSL and have changed exactly nothing since the server was set up. I've tried having the mail clients use SSL/TLS in response to the above error, but that changed nothing.

I havnt, intentionally, addressed this issue (not for initial want of trying), but after having given the matter up for some time, today i closed the lid and was expecting it to go to blank screen, but no it went into suspend (despite not being instructed to do so in power management), crikey i thought here comes a forced shut down and a dicey boot, but lo she woke After an initial second of smeared-up graphics and the sound of the hard disk starting to spin twice in a row, she woke.
On closing the lid again it went to blank screen, a fluke i thought, so i changed the options to suspend when lid closed in power management and tried again, and it worked, again, and again and again. Any other ppc users noticed that suspend now suddenly works?

I am used to setting up users and groups on my daughters computers with Ubuntu installed.
user: magz (daughter)
user: nigel (me)
group: nima
We each have our own folder for files i.e. magz and nige. This has always worked well and it didn't matter which user is logged in we could create and access files in the other users folder with full permissions.
root@nbsq: /media/2xfi/files# ls -l
total 8
drwxrwxr-x 9 nigel nima 4096 Jul 13 09:45 magz
drwxrwxr-x 3 nigel nima 4096 Jul 13 09:45 nige
I have finally got around to getting her to try Debian which I always use, however I have never had to set up users, groups etc in Debian (squeeze) so I just did what I'm used to with Ubuntu. What I've found is that if I create a folder while I am logged in then that folder cannot be accessed by my daughter when she is logged in and the same applies if she creates a folder then I cannot access it when I am logged in, unless of course I use terminal to change the owners. In each case with the new folder the owner will be: root and the group will be: root. I would have thought what works for Ubuntu would work for Debian, however there must be differences.

I'm using a Ubuntu Desktop 10.04 32-bit machine as my file server. It is sharing a few folders stored on a USB NTFS drive using Netatalk. The client machine is running MacOS 10.6.4. I have only one user on the Ubuntu machine, but the Mac machine has two users. I wish to share the same network share between the two Mac users, while both are logged in (they switch between one another without logging the other one out).
I created a login item on both Mac user accounts to automount the Ubuntu shared folder and used the same Ubuntu user account for authentication on both Mac accounts. This is the problem: When the first Mac user logs in, the shared folder automatically mounts with no problems. However, when the second user switches to their account (without logging out the first user) the automount mounts the folder with a red "No Access" sign on the folder. The only way to resolve it is to eject the mount and manually remount.
This is not the end of the world, but I would like to resolve this issue if possible, so that the users get a smoother experience. The way I tried to resolve this: I thought that maybe Netatalk does not allow the same user to connect more than once from the same IP, so I set up an additional user on the Ubuntu machine. when I connect to the Ubuntu server using the new user for authentication, the only share available for the user is their home folder. The other shares are not available.
I therefore tried to configure permissions using the AppleVolumes.default by explicitly giving all users the "allow" permission for all shares and restarting the Netatalk service, however the new user still has access to nothing but their home folder. How can I share the same shared folder between multiple users?
