Ubuntu Security :: Setting Up Keys For Ssh For Multiple Users?
Jan 30, 2011Ubuntu 10.10 Server is loaded. Openssh has been loaded.
I have multiple users which need access to server via ssh.
My impression from reading about ssh is that a key needs generated for each person. Thus, each key will have a passphrase that is unique to them.
In /etc/ssh/sshd_config, the default sshd_config suggest using:
%h/.ssh/authorized_keys
My assumption is %h is a variable that will allow the current user to use the public key stored in his home directory under the .ssh folder in a file called authorized_keys. Is their a command string that automatically populates the authorized_keys file?
I am surprised that even though there are a number of hidden (e.g. .****) files located in the home folder, there is not one automatically generated as .ssh. It appears I have to create that directory myself. I am especially surprised by this since it appears the instructions for generating a key seems to load the key in the home directory instead of proceeding to create a .ssh folder to store the keys in.
It is not clear, but it appears that the public key needs to be copied or appended to the authorized_keys file, but, using the scheme above, the public key needs to be copied or appended to each users authorized_keys file instead of appending all public keys to a single authorized_keys location.
It then appears that each persons authorized_keys file needs permissions set to 600.
It also appears that if I decide to use RSA instead of DSA, I would do the same thing above but would use authorized_keys2 file instead.
Why doesn't the home folder which gets automatically set up for each user automatically get a .ssh folder generated? i.e Why does it have to be created by hand? Does it need the same permission on the .ssh folder? ie 600?
My aim is to allow many to log on via ssh simultaneously and then allow many to simultaneously vnc into their respective gnome desktops.
Security :: Setup File Permissions For Multiple Groups/users That Use Windows?
Nov 2, 2010I have a remote directory shared over NFS called tech with perms set as 0750 and owner set to root:tech. I have 2 groups: tech, and techAdmin. tech can read and execute within tech/. techAdmin can read, write, execute. I have 4 users: user1, user2, user3, user4. user1 and user2 is a member of techAdmin, user3 and user4 are members of tech. simple so far...but wait here's the problem.

Security :: Sudo For Users But Only +r On Other /home/users Ubuntu 10.04 ?
Nov 1, 2010We are trying to set up a classroom training environment where our SIG can hold classes for prospective converts from Microsoft/Mac. The ten machines will have /home/student01..10 and /home/linsig01..10 as users. We want /home/student01 to be able to explore and sudo so they can learn to administer their personal machines at home. We don't want them to be able to modify (sudo) /home/linsig01. I've seen the tutorial on Access Control Lists but I'd like other input so we get it right the first time.

May 13, 2010We have just installed VNC. It seems to work fine. If we connect to a remote system using VNC, on say DISPLAY 5, it works and we can run our applications. If another person wants to view this session, they can also connect to DISPLAY 5, and it is fine.
However, if you are just sitting at your own system, without using VNC, and someone connects to your system using VNC to DISPLAY 0, so you can show them what you are doing, they do not see your session, they see a plain startup session, not the session in which you are running your applications... How do you let VNC users see your normal non-VNC session? Have I configured something wrongly? We are new to VNC!

Ubuntu :: Can't Add Neww Users Guest Session Not Working
Mar 19, 2011Ubuntu 10.10 x64.It's been a little over a week since I *rebuilt my system after a gdm or gnome issue and now I'm having an issue with the guest session not working and I'm unable to add a new user. It says "incorrect data" or something like that. This is more than annoying. Why is my system decaying so rapidly? I'm not adding anything to the system that isn't approved by Ubuntu. it's virtually a stock build, minus some changes to the look and feel category. Is this possibly a security issue? My routers up and running and I turned on UFW.
.1) Can't add new users
.2) Guest session will not start.
.3) Should I be concerned about my security?

May 12, 2010I have an environment with multiple projects that have a variety of government and commercial sponsors. We have been satisfied to this point with a netapp serving nfs/cifs and keeping a tight reign on nfs exports.Some of these projects have started asking us to provide access restricted sub-folders of the project space based on different groups that contain a user subset of the primary group.
We have a linux machine that serves as a version control front end to the netapp, mounting the project spaces via nfs. People are now mounting their project space via sshfs to this "front end" and sharing the root password of this sshfs client with everyone in their project, in turn creating a security hole to access the so called restricted sub-folders. I know all the obligatory responses referring to irresponsible user behavior but would like to see how others have addressed something like this where user behavior seems out of control.

Ubuntu Multimedia :: Sound From Multiple Users On Same Box?
Feb 3, 2010Ok, for various (mostly security) reasons I was experimenting in running certain apps as a different user id (on Karmic).
I can get X to forward to my main session without a problem but I cannot get the sound to work. Sound works fine in my main session, but when I run sound as another user I get plenty of errors like:
PHP Code:
ALSA lib pcm_dmix.c:1008:(snd_pcm_dmix_open) unable to open slave
I am not a big linux GUI person, so I have rarely dealt with sound systems under Linux. What is the simplest way to get this to work in a relatively secure way? (I do realize that my security is already a bit compromised by allowing the secondary user access to X, but that can't be helped)

View 2 Replies View RelatedUbuntu :: Multiple Keyboard Layouts For Different Users SSH
Feb 7, 2011I work in a company where the Ubuntu server is managed by different people around the world.
Day-to-day admin : me in France with an Azerty keyboard
Level 1 24/7 support : team in US with a Qwerty keyboard
Of course there's commands like sudo dpkg-reconfigure console-setup but this one affects the whole system. I've searched quite a lot on how to change the keyboard layout for one person only, but it always relates to the Gnome interface. So I'd like to know if you knew a way to locally change the keyboard layout, only the SSH connection of the user? Maybe in the startup scripts of the bash session, or even better, when the user types his user login (so it detects his language and automatically switches to the right keyboard).
