Is there a way that a user without root privileges can read this value?
OpenSUSE Install :: User 'root' Can Read The Content Of The File
Apr 12, 2011I came across this issue today and it changes everything I know about file permissions in linux. I created the following files in my system :
Code:
/tmp> ls -lad /tmp/testperm/
drwx------ 2 sagi users 4096 Apr 12 20:23 /tmp/testperm/
/tmp> ls -lad /tmp/testperm/file.txt
-rw------- 1 sagi users 12 Apr 12 20:23 /tmp/testperm/file.txt
[code]....
One more thing, as you can see I also set that only the owner of the directory (which is me again) can read and cd (the execute bit) to the directory. how come user 'root' can read the content of the file ?
Code:
# id
uid=0(root) gid=0(root) groups=0(root)
# cat /tmp/testperm/file.txt
Hello world

General :: Setting Read Permissions Of A Directory For Root User Only?

Networking :: Run The Job Under A Root Account And Deny Read/write Access To A Normal User?
Jan 18, 2010I'm setting up Ubuntu Karmic on my sister's old computer for my nephew, he's quite young so my sister asked to install some content filtering. I'll first setup an OpenDNS account and I've installed and managed to get dansguardian and squid working on a virtual machine to try it out. so far it's working pretty well, but I need to secure it form the inside out.
I was thinking of blocking specific outbound ports so he could not bypass the proxy. because by default the firefox configuration can be easily changed. so I have a couple of questions.
1. is it possible to block outgoing ports on Ubuntu?
2. is that the best method?
3. is there anything else I should be aware of to prevent subversion?
lastly, this question is probably unrelated to this board but I've set up a cron job to update a dynamic ip with OpenDNS, the problem is that the password is in clear text in the user's crontab, can I play with permissions? is it possible to run the job under a root account and deny read/write access to a normal user?

Oct 26, 2010I no longer have access to my root desktop. On a session I attempted to change the root username but i apparently assigned it a wrong directory that does not exist. When I rebooted with my new root username, i was instead recognised as a simple user (no root privileges). I tried the console to change to "old" root but root password is not accepted and there is no way to access to sudoer files. it seems that inserting a new username requires root privileges and i am back to square one. Simply logging with old root username and password after restart gives me a blank screen with nothing on it and cannot even reboot.

Jan 21, 2010Prelude: OpenSUSE 11.2 (2.6.31.8-0.1-desktop), installed Novell client 2.0 SP2 (novell-client-2.0-sp2-sle11-i586.iso).
I found that if any usual user is logged into a NDS-tree, then _local_ root has full access to user's network shares, including the user's home directory located on remote Netware-server. Is it by design or
have I missed something? Nevertheless in windows local admin has no access to network resources mounted of any other user. If you runas shell (as admin) then admin in principle can't "see" network shares which were mounted (connected) by other users - they are accessible ("visible") per session.

View 4 Replies View RelatedUbuntu :: Read-only Root And Can't Edit Fstab
Apr 19, 2010I was unable to boot into Ubuntu 9.1 today because the file system is now read only. When I check fstab, it shows "ro" but I can't change it because it's on a read only file system. I tried umounting the root then remounting with read/write access, but I was unable to umount the root. I also tried booting with a live CD, but all I can find is the root.disk file, I can't see any of the file structure. That's probably just how it is supposed to be, but I'm new to Linux so I found it strange. method to either change the disk to read/write besides this?sudo umount /mount -o remount,rw /The other option would be to somehow mount the disk image while using a live CD so that I can get to the fstab file and edit it.
View 9 Replies View RelatedGeneral :: Make A File Read-only Even For Root?
Jun 2, 2010Remember back in the days of MS-DOS, a file could have 4 different attributes: archive, read-only, hidden, system. As you know, MS-DOS didn't have any user rights or privileges. Files had no owner. If you were at the command line, you could do whatever you wanted, you could change or delete any files you wanted to... so long as they weren't read-only. Under MS-DOS, if you had a read-only file and tried to delete it, you would get an error saying "Cannot delete read-only file". There was a simple remedy to this, just turn off the read-onlyness:
Code:
attrib -r hello.txt
The point I'm trying to make here is that even though you had full permissions over the file, you still had to turn off its read-onlyness before you could make a change. Well I'm trying to do something similar in Linux. Under Linux, the root user has full permissions over every file. But I need to make a particular file read-only so that not even the root user can alter it. I have a few programs on my computer that need to be run as root because they do some low-level networking (raw sockets and the like), and these programs alter my "/etc/resolv.conf" file. Well I need to find a way of making my "/etc/resolv.conf" file READ-ONLY, even for the root user. It doesn't seem as though the Linux filesystem provides a means of doing this, reason being that the root user will always be able to alter any file it wants to. I was thinking though... there's some way I could turn my "/etc/resolv.conf" file into a virtual file of some sort, like maybe I could use some sort of mount program to mount the file as read-only... ?

View 5 Replies View RelatedGeneral :: Setup A Read Only FTP User?
Oct 19, 2009Hello, I'm trying to set up a read only FTP user; basically, they have the ability to browse a particular images folder and download, but not write (or delete accidentally). I've got it set up so the FTP user logs in directly to the folder, so I'm good with that; but they still have write permissions. We have an application built in PHP that copies image uploads to this folder; it also resizes them in the same folder. So in addition to the main FTP user (me) who needs write access to this folder, whatever the Apache/PHP user is (not sure?) also needs write access. Is there a simple way to affect read/write permissions on a user level?
View 4 Replies View RelatedGeneral :: Recommend For A New User To Read?
Feb 20, 2011This is my first post and there probably will be many more. I've used linux before for short periods but never really tried to learn it. I've decided that I want to study linux and learn as much as I can about it. I dont hate windows or OSX but I really like problem solving and using the command line. Which I used to love with DOS.
I'm going for a complete career change so I want to get certified in Linux by taking the LPI test so I can show employers that I have some computer certification(In Japan it really helps). Now, I'm studying commands and trying to do simple tasks(just playing now) but want to get into it more.
Question: What books do you recommend for a begginner with just dos and windows problem solving experience to start learning linux? Also, what programing language should I pick up a bit for linux?
Programming :: Cannot Prompt User In While-read
May 15, 2011I'm facing a problem in a - at least I though it would be - simple BASH script. I use 'awk' to find matching lines in a file, and then use while-read to modify each line matching the expr casted in awk. It looks like this:
Code:
function foo() {
awk '$NF~/^./{print $NF}' FILE.TXT|while read line; do
bla bla bla ...
[code]....
However, each time the execution hits the 'read choice' line, it doesn't prompt - as well as pause the excution - the user for a choice: it just passes it. This problem just happens inside the while loop.

Mar 4, 2011I need to change a filename but when I boot up I get the message root device is read-only. Is there a way of changing this so that I can change the filename. I have a Mac Pro running Leopard OSX. The graphics card an NVIDIA 7500GT or driver has failed. It was suggested elsewhere that I change the relevant kext files to filename.kext.old, which I did, now when I try to boot start in OSX I get a message in various languages telling me to restart. I have tried booting in safe mode and from original Installation CD. In Safe Mode I get the same multi language splash screen, from CD I still have the graphic card problem, screen freezes and artifacts appear. So I boot up straight into CLI by holding down CMD-S hoping to be able to change filenames back but it says device read-only.

Server :: Openldap 2.3.43 Directory Read Only User?
Mar 8, 2011I have no ACLs in place yet but want to use a user called ldap-auth-user to bind to the ldap servers directory from the client servers. However I keep on getting ldap_bind: Invalid credentials (49). Error. I know the UserPassword is correct because I can log into a server using that id and password through the LDAP directory. I am guessing it has something to do with the way I created the account.
This Works:
ldapsearch -D 'cn=Manager,dc=test,dc=com' -x 'uid=testuser' -W
This Doesn't:
ldapsearch -D 'cn=ldap-auth-user,dc=test,dc=com' -x 'uid=testuser' -W
Here is the ldap-auth-users entry in the directory
