General :: Intruders Can Log Into Box Using Run Level 1 Without Using Password
Mar 23, 2010
Well I have been using linux for sometime, and have kept strong passwords for every user account. But recently I noticed when we boot into run level 1, it does not ask for any password.This means that anyone can turn on my computer in my absence, on grub menu press a, then 1 to append 1 to the kernel arguments, which will make my system boot in run level 1.It won't ask for any password. Once in run level 1, the intruder can easily access my files, copy them, change their permissions, change even the root password.
Now how can I make my system more secure? Is there a way to get detailed info of each log in session, like which user, which run level, for how long and things like that?

When I log into Mint8 ,for example, the bottom bar (task bar) shows activity I did not start eg, keyboard amongst others. System logs are suspicious:
an 9 22:23:24 patti-desktop dhclient: DHCPACK of 192.168.0.100 from 192.168.0.1
Jan 9 22:23:24 patti-desktop dhclient: bound to 192.168.0.100 -- renewal in 40777 seconds.
Jan 9 22:23:24 patti-desktop NetworkManager: <info> DHCP: device eth0 state changed preinit -> bound
[code]....
'patti-desktop' is not the user I'm trying to login to but its was and still exist a group (ops). Also having difficulty using sudo but that might be my error. Is there a program I can use see what is going wrong correct it.

hello everyone, im having a problem when my computer enters in the run level 4 as the default when i start slackware. The strange thing is that it not seems that is a X window problem, it looks like more like a configuration problem in some part of the kde script to initialize the log in, because if i manually start the X service it works fine, i dont know what is the source. Thank you in advance for the help.

I have a directory that has a another directory inside it. The top directory is rather redundant since it only contains the one other one. Is there a way to delete the top level directory and have the contents simply "move up a level"?

I am planning a trip for a few days and I will be staying at an inn with Wifi access. All the guests are allowed to use it. A friend of mine has been there, he told me there are several other private spots around the house, i.e. lots of other people using Wifi. My friend told me the inn uses WEP, so who knows how many times their access point has been hacked and accessed without permission...
My concern is that I will be there for a few days with my notebook, I will have to work once in a while, connected to the Internet. Is there some precaution I should take to protect my notebook from intruders? Is it advisable to install a firewall in my notebook (iptables?) or am I just overreacting? Is it possible for one of the guests or neighbors to break into my notebook?

Many of us maybe are afraid to by the fact that others are using our wireless connection (without permission of course). What is the command I have to run on the terminal in order to list possible logs of intruders?

I've been able to kludge a kill script which finds the correct pid for the kdeserver (or gnome server) after my system comes up in run level 5 so I can drop back to run level 3 mode. Lots of experimentation showed me that using telinit 3 and telinit 5 would occasionally leave the video memory in a mess and I would have the black screen of death.
I set the security parameter setting to autologin for me since I am the only user of my machine, but I still have to kludge the default setting under sysconfig (the DEFAULT_WM) under Window Manager to pick a certain window manager, so it takes time to manually switch the desktop.
Right now I can leave the gui and drop back to cli, but painful experimenting showed me that killing the X server is a no no. Right now I kill the kde server, which sends the SIGTERM to the X windows manager, which then figures out that it has to shut down.
Questions: Is there a better way of doing this? Apparently openSUSE figures that we have multiple users logging into the gui desktop, so the gui is always kept running and a login window with the desktop manager option forces the user to login in. With autologin, this never happens, but no choice of desktop is possible on the fly.
Can some type of script be set up to painlessly enable this to happen? And what is the best way of bringing either the Gnome or KDE desktop manager down gracefully? I do get lots of error messages as the system attempts to recover and X shuts down. It appears that apparently the single user with autologin is left out in the cold.

you can find a cutout of an output generated by "iwlist s" command for a cell. Does anybody know what Quality, Signal level and Noise level mean? What is the definition of them? I searched for it and could not find good information on it. What do these Extra:*** fields for? What does it show in the example above? How were those values computed?

Hi Guys,
here is my scenario:
I am running F10 x86_64 with Nvidia Quadro FX 3400.
I installed the drivers and it worked just fine. No errors generated according to Nvidia log files.
However, while in run level 5 when I try to switch to run level 3 by typing "telinit 3" or "init 3" the X server goes down and I get a blank screen. Same thing happens when I try to switch to a different tty session by <ctrl>+<alt>+F2 (or any F key for that matter).
I also noticed that when I shut down my system I can't see any more the screen where services are shutting down and their status ([OK] or [failed]).
Would appreciate your help on solving this issue.

I just upgraded to the 10.04 and everything works just fine as before (except for skype but that really doesn't matters as it has already been 3 years I'm using ubuntu and I managed to get it to work only once, for miracle I believe ^^). The only real issue I have is this: when I start up my laptop, after the log-in, no sound will be heared as the "speaker" volume level in alsamixer is set to 0; if I raise it from the terminal running alsamixer (as I don't know any other alternative) everything plays just fine, but the next time I boot I do have to do it all over again... So, how can I change the default startup level of the "speaker" in alsamixer?
PS: by the way I do have the very same issue with the screen luminosity but the other way round as is always starts at maximum brightness and I can't manage to get it to start at the minimum, as it did before. At least reducing the backlight if far more quick but a couple of times I forget it and the battery lasted something like half an hour

I gzip directories very often at work. What I normally do is
tar -zcvf file.tar.gz /path/to/directory
Is there a way to specify the compression level here? I want to use the best compression possible even if it takes more time to compress.

I was trying to learn more about xorg configuration and came through an exercise that should be run at run level 3. So, I wrote init 3 in the command line then the x server stopped and the system was trying to enter run level 3 but then it hangs and nothing happens. At that time I was connected to the system via putty and wrote the command init 5 and the x server started again normally. I tried init 3 again and had the same thing.

While playing with my Linux box, I edited rc.sysinit in /etc/rc.d/ folder. But now when I boot into run level 3 or 5, I get complain that system cannot run /etc/rc.d/rc.sysinit. I boot into run level 1, and checked its permissions, which is rw-r--r-- . It should be rwxr-xr-x. I tried to use chmod to change its permissions, but it responded that "Read Only file system" Now how can I change its persmissions when in run level 1. In run level 3 and 5, machine does not boot. My box has Fedora Core 2 with kernel 2.6.20.

There must be a way to perform privileged tasks in the Gnome desktop (or actually Nautilus, I guess)...similar to using SUDO in a terminal window.
For example I want to change the rights to a file, but Nautilus tells me I can't because I'm not the owner.

I have used Awk in the past to isolate the file name from a given path..that is to say, I may have a list of files contained in list.txt.Can someone please post the Awk command that would do this? (I assume it will be very similar in form to the Awk command I showed above.)The point is, sometimes I may want to isolate the second directory, sometimes I may want to isolate the third directory or tenth or whatever - so I am hoping that if someone posts the Awk command to isolate the second level directory (to produce the output I showed in Fig.3) it should be fairly obvious by looking at the form of this command how to alter it and so isolate any other directory I want.

I am an absolute Linux Beginner who is being required to do a bit of admin work because the boss just fired the old linux admin. Unfortunately, one of our employees cannot remember her password to her email account and as such I need to reset it on our linux server.What I want to check is that this email account is actually a linux user account and I simply will reset the password for it using the passwd command from the root login. Is that correct?
