Security :: Permissions For Chown - Command Executed By Root Only

Feb 22, 2010

Inspite of having 755 permissions on the chown command, it seems the command can be executed by the root only. I was under the impression that the 'x' permission for 'others' can give executable rights to the normal user too, which does not seem to be the case here. Just curious to know, if not the file perms itself, what controls the execution of the command?

Security :: Log All The Commands Executed By Root ?

Aug 11, 2010

I want to get a of log all the commands executed by the root user with the following details :

incoming ip
username (thru which su was executed)
time and date
all the commands executed as mentioned above.

Also if user has managed to login as root, he should not be able to disable / delete the above info. Can this info be collected at some other physical server ?

Security :: Add Root Permissions To User ?

Jun 5, 2010

How do I add root permissions to my user account?

I want full permissions for all computers in my house, without having to get up and go to the other room and change permissions for the file, folder, drive, directory, computer, etc., then go back to the other room again.

I just created a partition, as THIS user, THIS machine, rebooted, and cannot create a folder on the partition I just created. UGH. No more of this stuff... I guess at the very least, I'll still have to log onto each machine for this?

Ubuntu Security :: Anyway To Get Nautilus To Give Root Permissions On Server?

Mar 30, 2010

I have recently secured a server by preventing root from logging in via SSH. Now I log in with a non-root account and use 'su' when necessary.However, now I can't do something I used to do, which is open 'sftp://user@ipaddress' in nautilus and be able to edit files as root. Is there anyway to get nautilus to give me root permissions on the server? Or at least end up with root permissions in a GUI text editor on my computer? I don't mind if I have to use bash to start the process, once I can get a GUI for editing files.

Note 1: Yes, I realize I could ssh in and use nano/vi etc, but I'd rather use my graphical text editor.
Note 2: The server does not run X, so I can't just forward it.

Software :: Command Line: Chown Command Recursively On Invisible Directories?

Oct 25, 2010

I tried


chown -R owner:group *

which does not work on the invisible directories (why?). When I used ".*" as wildcard it changed all (visible) files including the parent directory (the one I was currently working in which is the "dot") . I can change the invisible directories owner and group using dophin but how is it done from the command line?

Ubuntu :: Chown As Non-root User (with Authentication)?

Sep 19, 2010

I am currently responsible for administering a shared Ubuntu machine with several unrelated users. Some of these users own multiple accounts and would like to "chown" files between them. Currently, I must handle such requests manually, and this is inconvenient.

I am looking for a way to allow non-root users to chown files with authentication (i.e. prompt for the password of the user to which ownership is being set to). This would prevent an exploit such as:

cp /bin/bash ~/sudobash
chmod 4777 ~/sudobash
chown root:root ~/sudobash

Does such a solution exist?

General :: Root Can't Chown Mount Point For Samba Share?

May 30, 2010

I have a samba share that I mount locally at boot through fstab. The share is writable and if I access the share directly, say with konqueror and smb (smb://hostname/sharename) then I can do anything I want (create, write, delete, edit, files/directories). I have a mount point on my local machine



and I (username dtest) was unable to do anything except read files and create directories trying to do them to the local mountpoint except as root. I figured it would be a matter of


chown -R dtest /shares/mp3

but I was unable to do that even as root, I kept getting permission denied. When I did


ls -alt /shares/ it told me the owner was 1000 and the group was root. Dtest was already a member of the root group and I was able to


chmod -R 774

as root but I still couldn't do anything except read and create directories directly via the mountpoint. Ultimately I solved this by changing the uid of user dtest via kuser and then just chowning my home directory back to dtest. It seems like as root I should be able to change the owner of the directory. I know it's because this is a samba share, but it doesn't make any sense why root couldn't just chown it. Is there another way to change the owner of a directory, or is this set by the machine hosting the samba share?

General :: Chown - Set The Permissions Of An Entire Directory To "all"?

Jan 17, 2010

I set up a samba server on my Linux box for the purpose of allowing everyone - and I mean everyone - on my LAN network to be able to put files to one folder... The only issue seems to be not having write permissions to the target folder.

Question, re-stated: How do I set the permissions for an entire directory to not require anyone to have a login? I have tried many things, such as "chown -aR /data/public", but I still cannot seem to find the magic words.

Fedora :: Search Path - Yum & Rpm Commands Fail When Executed As Root

Jul 15, 2009

I've setup dimdim (opensource, centos 5.3) and noticed yum & rpm commands fail when executed as root because it uses librpmio from openoffice3 instead of /usr/lib (I'm running from memory so I may have misstyped). But sudo doesn't have this problem.

How can root's search path be different, especially after I state /usr & /usr/lib at the top of /etc/

Fedora Security :: Suddenly Root Password Invalid For Su Command?

Apr 9, 2011

I have recently installed Fedora 14 on a new computer we presented as a gift to my sister-in-law. She is new to Linux. Although I've used Fedora since Core 1, I'm no expert on security issues, and this baffles me. She's doesn't know how to change the root password, so why doesn't it work any more? She discovered the problem when attempting a yum update from a terminal.(1) How could the root password have gotten changed? How likely is it that someone got onto her system through ssh, made a lucky guess on her root password, and then changed it? Are there robots that do this?

(2) The firewall is enabled. I have it set up as follows: (a) under "Trusted Services," only ssh is checked (I need to be able to get in remotely this way); (b) under "Trusted Interfaces," I have eth0 checked (I need to be able to use VNConto her desktop).Question: Are these settings giving ample protection? What settings would be recommended to protect her system while at the same time allowing me to access it through ssh and VNC?

General :: Security - Copy Password From Mono-executed KeePass2 To Xterm?

Apr 7, 2011

I use KeePass2 to access username/password information in a Dropbox file. This allows convenient access from multiple devices. I can't seem to copy a password to the clipboard on my Linux system, however, in order to supply the password to a prompt in an xterm(1). I've tried both Ctrl+C/Ctrl+V and highlighting and mouse button 2 clicking. The KeePass2 program on the Linux system is executed by Mono.

How can I copy the password to the xterm(1)?

[Aside: I think we need a "KeePass" tag.]
