Fedora Security :: Make The Root File System Read-only

These are:

Fedora Security :: Log Files Empty - System Does Not Allow Root To Login ?

Feb 2, 2010

For a month or so now, I have been enabling ssh and opening port 22. I cron'ed the start and stop commands to leave them open only a few hours a day. After a bit, I checked my logs to find that some IP or another was attempting to brute force my root account.

I took little real threat by the offense.

(1) my system does not allow root to login and

(2) it would cut them off sooner than later when my system issued the stop command.

fast forward

Today I log in to find that all of my log files, as viewed from the gnome log file viewer, were empty of entries from about noon yesterday and prior.

Though I haven't noticed anything at all out of the ordinary with my system, I would like to get more opinions on the matter. Would there be any conceivable way that this was an automatic system routine, a clean up action of something? Additionally, if I was indeed the victim of a hack, what can I do to further protect my system (keeping in mind that I do want to access my system via ssh from time to time)?

Fedora Installation :: Newaliases - Root's Mail Is Not Showing Up In My Local Mail Inbox ?

Jun 14, 2009

I just added my login id to /etc/aliases to forward root's local e-mail to my local e-mail account in evolution.

As always, when I make a change to /etc/aliases, I run newaliases. I now get the following, and root's mail is not showing up in my local mail Inbox:


Is this correct?

I understand my hostname (i.e., Eng-Lab-010) is not a fully qualified host name, but I never had a problem before. But it appears this not a good thing. What should I do?

Mar 3, 2010

I'm using Gnome and I'd like to still have the ability to reboot/shutdown from one particular account as well as root. How would I modify the chmod command to add this ability?Also, I have a few users who just will hold the power button in to shutdown the machine.

Debian :: Forward All Root Mail To External E-mail Account?

Jun 28, 2010

The question is pretty much the same as the subject. I have a bunch of debian servers - most of them running exim4 default installations configured as internet site using dpkg-reconfigure exim4-config. It can send mails fine from php scripts and some other applications, but I can't seem to find a way to forward all root mail to some external address. I have tried adding "root: someaddress@example.com" to /etc/aliases and run newaliases command, but it doesn't seem to work.

General :: Terminal - Deciphering Information From Top?

Aug 5, 2010

In top, I can see programs that are sleeping but are taking up memory and CPU. If a program is sleeping then how is this possible? Maybe it might have some memory reserved but then what about CPU? Also, it says there are four users, but I can see only two users, myself and root. How can I find out who the other two users are?

Ubuntu Security :: Access To A Virtual File System For The Thermocrom Without Needing To Launch Owfs As Root?

Feb 12, 2011

I have been trying to use my DS2490 USB to serial device with a Maxim .DG1921G thermocron with owfs. It is supposed to give me access to a virtual file system for the thermocrom without needing to launch owfs as root.

/var/log/messages gives:
Feb 8 16:22:45 norman-HP-G56-Notebook-PC kernel: [ 236.140141] usb 5-1: new full speed USB device using ohci_hcd and address 2[code]....

but if ds2490 module is loaded it works when run sudo.It seems from this that it is a lack of permissions to USB but I have tried all the methods on at http://owfs.org/index.php?page=udev etc. to overcome this and a few others but none work.I am running Ubuntu 10.10 kernel 2.6.35-22-generic #33-Ubuntu SMP

Ubuntu Security :: Giving Root Permission To An Application But Without Running It As Root?

Jan 20, 2011

want to run VirtualBox with root permissions. Trouble is that only when run as root i can access attached USB devices inside of a virtual machine, otherwise, these a greyed out).Now running VirtualBox as a root user also changes the configuration folders, making all my virtual machines already defined disappear. I also don't want to copy all to the root configuration folders. Is there a way to give the VirtualBox root permissions but without actually running the application as a root user. Is it possible to do without changing the permissions of the non-root user, i.e. i don't want my user to have all root permissions, due to security considerations.

Fedora Security :: Become Root Without Root Password?

I found this on Bee's website. For more info on this exploit there are links there:[URl]..All you have to do in Fedora 13 is enter the following lines in a shell as normal user:


I don't think this can be considered solely an "upstream" problem, because I first tried it in Arch using the same version of glibc, and the final command causes both gnome-terminal and xterm windows to disappear.

Ubuntu :: Thunderbird Sends Mail Only When Started By Root?

Dec 23, 2010

I have 2 email accounts set up in Thunderbird - one is gmail and the other was given me by our server admins few years ago. Everything works fine on windows but when I try to send something from the second account (not gmail) in ubuntu it says that password is incorrect. Ive double checked all settings and seems like everything set correct. Now the most interesting part: when I set up this account as root (gksu thunderbird and then do same as I did under my account) everything works perfect.

I found only one thread at this forum with same issue and sure it's not solved [URL]..

Fedora :: Root Mail Going To My Boss / Undo It?

Jan 14, 2010

I just started a new SysAdmin job on Monday Jan 11, 2010. My predecessor left before I joined the company with NO documentation. All of the system mail (alerts, error messages, informative messages, etc.) that's going to root is being redirected to my boss. I checked .mailrc and /etc/aliases for an alias that would equate root with my boss, but couldn't find anything. My boss doesn't want to be receiving these emails. Where else can the previous SA could have done this operation. How can I sub my email address for that of my boss' to be receiving these alert messages.
