Ubuntu Servers :: Restrict Users To Only SSH Tunnel - No Shell?
Jul 21, 2011I have an Ubuntu 11.04 instance running on Amazon EC2. I am currently using it as an SSH tunnel/SOCKS proxy. Most of my Net activity is on a Windows 7 machine running PuTTY. This setup is working very well. So well that a few of my friends have expressed interest in accessing it. Question is, how do I share this proxy, without giving away my private key and root access? I would like to limit users to only being able to set up an SSH tunnel/SOCKS proxy, with no shell access. What other security measures would you recommend for such a setup? I googled a bit and saw references to rbash and chroot. I have already changed the SSH port, and set the EC2 firewall to allow inbound SSH only from my ISP's address range. My friends use the same ISP. They would probably be running Windows 7/Vista, and PuTTY too.
View 4 Replies View RelatedUbuntu :: Grsync - Filtering File Types / Getting Only Some File Types Getting Included And Not Others?
Sep 1, 2011I'm using Grsync and I want to be able to plug in any drive into my laptop and run rsync on it to back up all the user documents on there to another external hdd and to exclude everything else. Working on the principle that user documents don't always appear where we'd expect I want rsync to look through the whole drive and filter what it backs up by file type. I am only having partial success, however.
I am using the 'filter' option in the 'additional options' box. I am using the command
Code:
filter='merge /home/tim/Desktop/filter'
and I am attaching the filter file I have written. (I have added the .txt extention to upload it).
I have tested this script on my home folder and here's what's going wrong. Rsync will copy the entire directory structure regardless of whether there are any files to be copied over in those directories. I am also getting only some file types getting included and not others. .odt and .ods files are copied, for instance, but not .doc or .rtf.

May 11, 2010I want the users to access servers via ssh public key only. By default they don't know their initial password and do need to change that when performing administrative tasks.For changing their passwords without knowing the old they need to switch to root for this special case.The only case it seems I don't have control is that users can not only change their password but also the password of other peoples. Does someone sees a solution (without apparmor/selinux and special /usr/bin/passwd.sh) to restrict users to only change their password?I miss the feature of using environment variables in sudoers file.

Ubuntu Servers :: Handle Webroot Permissions When Uploading?
Jul 29, 2011I have been plagued by this for some time. How many times do you need to run chown -R user:www-data or similar to your webroot directory.I have been searching via Google and this forum. I have yet to find a definite answer to handle uploading and creating new files usable by apache2.Scenarios can vary. Some folks put there webroot inside a /home directory. Some users leave the default location as /var/www.I have a two part question.. Why do I often read "Apache runs as user=www-data, therefore files need to be readable by such (www-data)", but the default install in Ubuntu includes an index.html with the following?
Code:

General :: Copy Certain File Types Recursively While Maintaining File Structure On Destination?
Jun 14, 2011I have just been bothered by a fairly small issue for some time now. I am trying to search (using find -name) for some .jpg files recursively. This is a Redhat environment with bash.
I get this job done though I need to copy ALL of them and put them in a separate folder BUT I also need to keep the order intact after copying.
For e.g - If I get a JPG file under /home/usr/new/1/ then the destination also needs to be /test/old/new/1/.
At the moment, I am simply putting all files under /test/old/ and I can't somehow get the later /new/1/ folder path created under /test/old/
I understand this could well be done using while OR if else loop, though if someone can just guide me with a hint, I would be really grateful.
I will complete the rest of the steps and was asking here since I am still not comfortable with the shell/bash scripts yet and planning to be really good at it over the next couple of months.
Ubuntu Servers :: Folder And File Creation - Can't Successfully Share Editable Files Between Users
Feb 18, 2010I'm trying to setup a Samba share for our work. I have it almost complete, however I can't successfully share editable files between users. The issue I'm having is that say User1 create a file test.txt, because of the 755 permissions, then User2, who has "writable" rights as per the smb.conf file, cannot edit that test.txt file.
Whevener I create a file with a user, its locked by that user. Is there a way I can set it that every folder/file a user creates is 777 ? I firgured that there's still security because of the "Valid users = " field in the smb.conf file.
