I run a system that users may log into either remotely or physically. Multiple users may be logged in simultaneously because of the remote access, but only one user can be physically logged in at a time.With the current setup, however, if the physical user inserts a flash drive (which the OS mounts automatically) then the remote users gain access to the removable media.

I'm looking for a virus scanner to scan some removable media (USB drives, mp3 players, etc). Since there's so many choices to choose from, can anyone recommend any?
I've heard a lot of people recommending clam av, but everything I've read suggests that clam av is better used for scanning e-mail servers and not home desktop application...
I would like to experiment a "green" idea of virtual desktop where multiple users are served by a single powerful machine.
I have a server running 24/7. The monitor of this machine is turned off most of the time and the OS is on the login screen.
Other users, in the same local network, use less powerful machines, which could be a thin client or an old Pentium 3 machine. They access their accounts remotely and work with the GUI as if they were sitting in front of the server. Each user sees their own desktop (different themes, screen resolution, etc.). And of course it can happen that several users could log in at the same time.
The usage is modest: mostly web browsing and the usual default applications (office, wine, gimp, etc.). In particular no games or any demanding applications. The users want to use their desktop in graphical mode only.
Question: How do we call this way of using a server? Is it possible with Ubuntu? And how to implement it?
I had remote desk running on a machine and I went downstairs the other day, turned it on, and someone was controlling the machine. Of course that's partially my fault since there was -zero- rd password set. However, my question is how did this person figure out my IP and get past the router to the machine? I don't have any forwarding setup. My router admin password is (has always been) strong. I guess my question now is: Is there anyway to restrict rd access to the local network?

View 5 Replies View RelatedI'm going traveling and I had the bright idea of putting my sensitive and irreplaceable files on an sd card. Then if I leave my stuff in a sketchy hostel for the day, I can easily take the card and might lose only a replaceable netbook. The problem is that I want some files to have 600 permissions (rw-------), readable and writable only by owner.
But no power on earth seems to be able to force a fuse-ified filesystem to pay attention. Whether I try "chmod 600 filename.txt" as the owner/user or as sudo makes no difference. Nothing works. The sd card is mounted with a line in /etc/fstab:
Code: Select allUUID=0000-0000 /mnt/64_GB_sdxc exfat auto,rw,user,exec,uid=1000,gid=1000,dmask=0022,flush,fmask=133 0 0
So the user owns the files and they have typical permissions instead of the automounted default of 700. That's all very nice, but I'd like to be able to change permissions on just a few files!
I'm using Fedora 12, and I want to mount/unmount my USB memory stick from the command line. I know I could edit /etc/fstab and so on, but I want to emulate what happens when you mount using the GUI (I use KDE and the device notifier), that is, I want to be able to do this as an unprivileged user and not have to know the mount point exists in advance.
I'm sure in older versions of Fedora there was a command something like `gnome-user-mount' which let me do this knowing only the filesystem label... What is the current equivalent?
I want to disable automounting removable media when they are inserted, especially CD and DVD. I use F13 and Gnome. I went through System/Preferences/File Management/Media and set everything to "Do Nothing", see below:
I have installed gconf-editor and verified that all automounting options are unchecked:
according to "/sbin/chkconfig --list" haldaemon is off and automount is not installed.
What else should I check?
I would not mind if USB (flash) disks were automounted

View 4 Replies View RelatedUbuntu 9.04 Gnome Desktop (although I have seen the same situation in other versions).When I have a removable media device installed such as a USB flash drive, a CD/DVD or an SD card in the built in reader I have a corresponding icon on the desktop. So here is my situation...I have a 16 GB SDHC card installed in the reader in my netbook as additional storage. As the main solid state "hard drive" itself is only 16 GB I leave the card in at all times. I would like to do away with the desktop icon as I never use it to access the SD card. Any way to do this? I believe it appear as part of the HAL process so perhaps it will go away with 10.04.

View 3 Replies View RelatedI have the following hardware setup:
a NAS running Debian that frequently (but not always) has two removable media attached,a Debian desktop that mounts the above NAS via sshfs,the aforementioned removable media are symlinked to the directory on tha NAS that is then mounted by the desktop.
What I'd like this setup to do is to immediately time out if mounts as unavailable. Instead, I only get the expected behaviour if the NAS is down (the ssh client takes about 3 seconds to do that); if it's up, the removable media automounts (they are symlinked to the directory shared with the desktop) seem to never time out, ever. This happens locally on the NAS as well, when ssh'ing to the NAS and trying to run `ls /media/Storage` or `ls /media/Backup`, these commands never return. It's as if systemd was ignoring the x-systemd.device-timeout setting on the NAS.
The relevant part of the NAS's fstab:
Code: Select all/dev/sdb1 /media/Backup ext4 defaults,noauto,x-systemd.automount,x-systemd.device-timeout=1s,rw,user,nofail,x-systemd.idle-timeout=30s 0 1
/dev/sdc1 /media/Storage ext4 defaults,noauto,x-systemd.automount,x-systemd.device-timeout=1s,rw,exec,nofail,x-systemd.idle-timeout=5min 0 1
[Code] ....
I find it highly interesting that despite both removable media being detached, only one is flagged as having a dependency failed. Both paths exhibit the hang behaviour, though.
What can I do to actually time out when the media are not there?
how to make removable media (e.g. USB sticks) not have any write caching. I want to prevent data loss when they are removed after file copying appears done but before write caches are written. I'm using Gnome on Squeeze.
I've found suggestions of adding the 'sync' mount option to /system/storage/default_options/vfat/mount_options in the Gnome configuration. However this doesn't seem to completely eliminate write buffering, as the drive activity light continues for several seconds after file copying appears done, and unmounting drives produces a dialog box which says to wait whilst data is written to disk.
I've just partitioned my hard drive with GParted so that I have space to install and run Windows OS based programmes such as Monkey Island (wine simply won't work) and other PC games. I have the Windows XP SP2 Installation CD but my OS (Intrepid Ibex) won't allow me to autorun the CD and proceed to installation.
Now having hunted around the net little, it seems the answer is System->Preferences->Removable Drives and Media. Problem is, I don't have a Removable Drives and Media option on this menu. Is there a workaround for this? E.g., is there a way of using the Terminal to enable autorun, or is there another way I can do this?As I'm pretty new to this thing, feel free to use short words and detailed explanations.
behavior in 9.04:plugged in a disk, mounted it and it as readable to the world.this is intended because it is shared via samba.behavior in 10.04:the disks have 700, meaning, they are not readable by samba.this is a problem.this is the best solution I've found so far:http://www.mail-archive.com/ubuntu-u.../msg10951.htmlexcept, that the mentioned means to fix this are gone.(gconf-editor -> ..., storage and preferences -> removable media)after 3 hours of googleing and reading I'm rather upset about this bug.so please, if you are thinking of suggesting fixed entries in the fstab or anything else that will not work with every media that is plugged into this box, just close this tab.

View 2 Replies View RelatedI have searched somewhat this forum but haven't yet found a similar post using the keywords I entered but perhaps there is already a similar post then please refer me to it.I am trying to add a user account "Guest" to allow people on my laptop without giving them access to vital parts of the computer. Basically, I want them to only be able to view their own home directory and access internet. Nothing more.I have set the group to "guest" and changed the other home directories of other users to owner access only.
Guest still has access to root and is still allowed to perform actions in various critical areas (deleting files from for example my Windows 7 partition). This I also want to prevent. I was thinking to set each directory's permissions to Owner and Group only and remove Others access.My questions:
1. Will this have any undesirable impact (programs of main user accounts not able to access certain directories)? For guest user I don't care as long as internet works.
2. When I start User Manager and disable for Guest all options except "access internet" (so I also disable access to CDROM), the guest can still access the CDROM. Does this mean the User Settings menu has no effect or is overruled by something?
We set up a server with my friend (still newbies ) a couple of months ago using Ubuntu 10.04 LTS server edition and agreed to let some folks at school to use it to install drupal on it for teaching and learning purposes. So the idea is that there are multiple users that all install drupal in their home folders separately using SSH and continue from there on etc.
Everything is set up for that to work (domain, settings etc), but there's one thing nagging me, and that's how everyone can look at everything on the server. They dont have rights to modify anything but can look at file listings and view inside files etc.
So how do I restrict the viewing rights of users to inside their home folder, BUT so that they can use the cd command to go to folders inside their home folder, but not outside of it. As far as I know rbash purely keeps you inside home and allows nothing else, so that doesn't work, because you need the cd command.
Because I was browsing around in KDE and found out that I can view other users files and they can view mine.
View 1 Replies View RelatedThrough some recent update, which one I am not sure, my system no longer responds to removable media such as flash drives and insertions of DVD/CD disks. Whereas before, for instance, if I inserted a USB flash drive, the "Device Notifier" would pop up, tell me that a new device had been detected, and ask me what I wanted to do with it, now nothing. "My Computer" (sysinfo:/)does not update either. The kernel knows the device is there, since I can see it when I do "lsusb". OpenSuSE x86_64 11.2.

Also, would this defeat the purpose since they could just wget from it if its still web accessible through a browser?
