General :: Hide A User From The Who Listing?
Sep 3, 2011
Is it possible for a non-root user to hide themselves from the output of who/w, so that they can be logged in without other users seeing it? I think that the file /var/run/utmp might have something to do with this, but it's not writeable by non-root users (permission 644). I'm fairly certain that this can be done by a non-privileged user (because someone told me that they were able to do so), but I don't know how they did it and can't ask them right now.

I presume that if this is possible it would need to be done as root (or as a user who shares root's UID of 0).How can a process be launched so that it does not show up in a ps aux or ps ef or top listing if the command is run by non-root?Is this even possible?The distributions I typically run are RHEL/CentOS and Ubuntu - so if there is a distro-specific answer, that's ok, too.

I have, for example, a folder called "MyFolder" and it contains 3 files: MyFile1, MyFile2, MyFile3. The only file that I do NOT want a particular user/group to even see that it exists is, for exmple, MyFile2.So, when they do a directory listing on MyFolder, they should only see MyFile1 and MyFile3. How can this be done in Linux? The important thing is that it is not just preventing them from "executing" MyFile2, but to prevent them from even knowing that it exists by not including it in a directory listing.This is a simpified example using one file, but in reality, I have lots of files and some of those that I want to block are also subfolders.It is very important for me to hide the existence of certain files/folders when the user does a directory listing. It's also important that the files stay in their current folder (that is, I can't use a workaround which requires moving all the files into a separate folder and then securing that folder).

I was wondering if it was possible to hide the File Systems from a user. So when then browse through folders or choose to save something the default folder is their "home" folder. I am using SAM Linux distribution and don't want my users to be able to screw anything up! I use thunar as my file manager and was just wondering if it is possible?

Once again, nobody seems to understand security properly when they decide to add nifty new features. After upgrading to 10.04 from 9.10, I now have a listing of all the user accounts under "Switch from" when I go the the logout menu at the upper right side of the task bar. This is a terrible security hole that should never have been allowed in the first place, and is just as annoying as the default behavior of listing all the user accounts on the login screen.

Today I found something really interesting (at least to me) on one of our test servers:
I can change into an existing directory from my actual working directory using a relative path, but that very same directory is not listed when using ls -a.
Here is the shell session (as root):
$ pwd
/you/are/here
$ ls -a
. .. <-- Note: "somedir" is not shown to root
$ echo $CDPATH
[Code]....
I had checked the automount thing mentioned by Gilles, but as I had changed to somewhere and issued a mount|grep somewhere there were no output.
Here is the lsattr and strace output as suggested: [URL]

This sounds like an old topic. I have an active user account in my system that I don't want it to be listed in GDM greeter. In the past (prior to Gnome 3), it can be achieved by configuring the "Exclude" option of the "greeter" section in the Custom.conf or by creating the user account with UID smaller than MinimalUID. But it seems the same old trick does not work for me in Gnome 3. I have tried the "Exclude" option with no effect at all. Using the UID approach only solves my problem partially, as it only exclude it in the GDM greeter during "switch user" but it still being shown in the list in the initial greeter after a cold boot.
Anyone know how to do this in Gnome 3?

If you need to to exclude one or mode user from your gdm login window you must edit "/etc/gdm/gdm.schemas" and add the user you want exclude from the <key> "greeter/Exclude" (near the other user in <default></default>)
When Fedora could have a gdm config again?

I actually got my boss to let me put Ubuntu on a laptop for a client and it works like a champ. I have it all setup but there's one thing I'd like to do on it. I have an admin user (the one I created during the install) and a desktop user (for the person receiving the laptop). I would like to hide my admin user from the login screen, so when it boots up all the user sees is their name. If I need to help them with something/install software I can choose other and login as my admin user.
It appears this was rather easy in 9.10 and previous but I can't figure out how to do it in 10.04. To be clear, I want to edit the user list, not disable it entirely. I've tried changing the user id, I found a post that claimed IDs less than 1000 were not shown on the login screen, this proved un-true in my case.

Does anybody know if it is possible to hide certain databases from the root user in MySQL?
It may sound stupid, since the root is the root and all that, and it may feel strange but it kind of adds a level of abstraction which I want to give the "root user", and I want to avoid going down the route of creating a new mysql instance on the server.
I had wondered if there is some kind of 'hide' parameter for a database or whether it is possible to change the root username to something else (e.g. 'realroot') and then create a new user 'root' with all the same privileges (except those on the hidden databases).

When opensuse boots up and shows the login screen. The login screen shows all configured user accounts to select from.
How would I hide these accounts for opensuse 11.3 with KDE and opensuse 11.4 with LXDE.

Firefox opens file listing instead of Nautilus opening file listing.When I access a folder via "Places" -> "Home Folder" or "Places" -> "Downloads", Firefox opens and list the contents of the directory.I have re-installed Nautilus, un-installed Firefox and then going to "Places" -> "Home Folder" or "Places" -> "Downloads" launches Nautilus and I can view the contents normally. Anybody else had this problem with Firefox ? Anybody know how to fix this Firefox problem ?Running Ubuntu Desktop 9.10 64bit.

I can't seem to find a way to do this, so maybe it's not actually possible, but I was wondering if there was a way to list all files that link to a file.
For example.
touch a
ln a b
ln a c
I want to find out what files link to a (not symlinks, mind you), assuming that this is more complicated (they are spread around to different directories).
I kind of understand about the filesystem storing links in one area and data in another, so I understand it probably takes more work to find a link from a file location than the other way around.

list filenames one-per-line, in BASH without including directories. I think he was either wrong or making that up. There is a way to list just the names and one per line but there aren't any arguments I can find that can be used to exclude directories.
Code:
IFS=', '; files=`ls -m`; for i in $files; do if [ -f $i ]; then echo $i; fi; done That does only use ls as a command, however he said his GSI thought he could do it without all that...

But I'm not sure how to get to the dir entry for the device.

Im using the top command and can get a list of all the cpu usage for all the process but cant only get the processes with 10% or more. I'd want these processes sent to a new file. Would I be able to cat the cpu usages and PID into a file?

following can be used to locate files that contain the contents 'SomeString' or 'SomeOtherString':
Code:
find /home/username/public_html -type f -print0 | xargs -0 egrep -l 'SomeString|SomeOtherString'
How would I limit this to searching for the text 'SomeString' or 'SomeOtherString', but only if the file has extension .php, .inc or .js? Also - what piping to xargs does here? I don't understand how this command actually works.

Is there a command to list all of the users I, as an administrator have created? It is difficult to tell the users I created from those created by the system by reading /etc/passwd. I thought 'man 5 passwd' would shed some light on this but is wasn't so

Is there a command to return a recursive listing of sub-directories and the number of files in them? I have found plenty of ways to give me the total number of files in a directory structure, but none that gives a list of the sub-directories with the number of files in them. "du" gives me a listing of directories with their sizes, but I couldn't find an option (or any other way) to give me the number of files as well. Ideally, I'd like to get list with "Size" "Files" "Dir name" - And the order of the columns doesn't matter. Is there a "simple" command line solution or do I need a shell script for that?

I have a user who just got a new laptop and when he connects to the FTP server, it verifies his username and password like it should, but when it goes to do the directory listing, it just kinda sits there. if i refresh the view, the folders show up. wonder if there's something in a log somewhere for vsftp i should be looking at. it could just be his ftp client or air card too, but i want to be thorough on the server too becuase it will help me learn.

suppose in my current directory, I have 50 sub-directories. Now, I am interested only in about 20 of those sub-directories (whose names match a pattern). I would like to recursively list the contents of these 20 sub-directories. How do I do that ? I would like to do this in Solaris 10 and Linux(RHEL 5.x).
