Server :: Iptable Rules Some To Save And Some Not To Upon Reboot?
Apr 17, 2010I am having a Xen server xend daemon is taking care of giving interface names like vif1.0 or vif0.2 to the connected guest operating systems on it.I can not save the current IPTABLE rules since upon reboot the xend daemon gives different names to virtual ethernet interfaces i.e. vif1.0 or vif3.0 or vif9.0 like that.I have some rules that I want to be active upon subsequent reboots and not all.Say for example an SSH to external server at port 8000 should forward the request to a machine on LAN.Which I have done by port forwarding from IPTABLES.So I need to save some rules.I was thinking to make a script which on reboot activates those rules.
I am not clear on where to do that.I came across internet and found /etc/network/if-up.d/I am not clear with this directory my question is if I make a scrip which has IPTABLE rules as I want and save it in above folder will it work. I am not clear with what is /etc/network/if-up.dfor.Suppose my logic is wrong then how should I go for it.Also I want to know does a protocol uses two port to make a connection.I have forgotten that thing,i.e if I run an SMTP or ssh then do they use port 22 and 23 both in case of ssh or 25 and 26 both for SMTP like that or just specifying the rules for one port will be enough.I tested these rules in a secure environment where i had disabled firewall and ssh forwarding on router worked well
Fedora :: Save Setting In Alsamixer - Get 6ch Every Time After Reboot?
Jul 21, 2010I change the audio channels to 6 in alsamixer by choosing my sound card and change the channels to '6ch'. But this setting is not preserved. I see that after a reboot the channels are again going back to 2ch. I have to manually change everytime to 6ch after each reboot. Is there a way to save the setting in alsamixer so that I will get 6ch everytime after reboot? I am not sure I have explained my problem in a way so that you can understand.

Apr 14, 2011I'm working on a Soekris net4801 that is running an unknown distro of Linux. The kernel is 2.4.29, and iptables is v1.3.4.
I can't work out how to save the iptables. I searched the whole system for files/folders containing the name "iptables" and got 3 results:
/user/local/lib/iptables
/sbin/iptables
/lib/iptables
I've tried iptables save, iptables-save and iptables save active.
"iptables save" and "iptables save active" give me an invalid argument error. "iptables-save" isn't a valid command. "iptables --help" gives me a list of valid switches, none of which have to do with saving.
how I can save the iptables?

Jun 16, 2010my mediacenter is attached to an beamer with the optimal resolution of 1280*720 ubuntu 10.04 doesnt offer me this revolution (on my intel 915 graphis controller). this means i have to add this resolution to the possible resolutions. first i used cvt
Code:
cvt 1280 720 60
and got this result:
Quote:
# 1280x720 59.86 Hz (CVT 0.92M9) hsync: 44.77 kHz; pclk: 74.50 MHz
Modeline "1280x720_60.00" 74.50 1280 1344 1472 1664 720 723 728 748 -hsync +vsync
then i added this to xrandr
Code:
xrandr --verbose --newmode "1280x720" 74.50 1280 1344 1472 1664 720 723 728 748 -hsync +vsync
and
Code:
xrandr --verbose --addmode VGA1 1280x720
now i can select and use the new resolution - until next reboot. after an reboot 1280x720 is again not available. even if i work with sudo - the resolution isnt there....

View 4 Replies View RelatedGeneral :: [FYI] "last -f <old Wtmp> -x Reboot Shutdown" Incorrect For Last Reboot And Shutdown?
Mar 25, 2010Further to this LQ thread which Tinkster solved by suggesting the last command (thanks Tinkster) I have been exploring last -x reboot and have found that the reported duration is incorrect for the last reboot and shutdown when a old wtmp file is used. Not having a record for the following shutdown, last assumes that the system has been up until the current time and similarly for the shutdown.
The output comes in time order, latest first, each line showing the time of the reboot and the uptime from then to shutdown. Using last -x reboot shutdown to show the shutdown time, here's an illustration
Code:
shutdown system down 2.6.29.6-smp Sun Mar 7 15:35 - 03:02 (11:27)
reboot system boot 2.6.29.6-smp Sun Mar 7 09:35 (05:59)
09:35 until 15:35 is 05:59.
When the uptime exceeds 24 hours it is shown as (<days>+<hours:minutes) like this
Code:
shutdown system down 2.6.29.6-smp Sun Feb 21 12:39 - 13:20 (00:40)
reboot system boot 2.6.29.6-smp Sat Feb 20 09:39 (1+02:59)
09:39 until 12:39 the next day is 1 day 02:59.
The time in parentheses at the end of the shutdown lines is normally the time until the next shutdown.
So far so good. The incorrect output is for the last reboot and shutdown of an old wtmp file. Here's the output of last /var/log/wtmp -x reboot shutdown; last -f /var/log/wtmp.1 -x reboot shutdown
Code:
[snip]
reboot system boot 2.6.29.6-smp Fri Mar 12 07:42 (01:54)
shutdown system down 2.6.29.6-smp Fri Mar 12 01:31 - 09:37 (08:05)
wtmp begins Thu Mar 11 08:25:26 2010
[snip]
reboot system boot 2.6.29.6-smp Wed Mar 10 14:12 (15+01:42)
shutdown system down 2.6.29.6-smp Wed Mar 10 12:41 - 15:54 (15+03:13)
[snip]
The boot started at "Wed Mar 10 14:12" which had an actual uptime of 1 day 11:20 is reported as 15 days 03:13 which is the time from then until the last -f /var/log/wtmp.1 -x reboot shutdown command was issued. The time from shutdown to shutdown is similarly affected.

General :: Save All Files Onto USB's
May 10, 2011I've been having some PC troubles since yesterday after downloading VistaOSx onto my computer. (I don't know why I downloaded it, I was bored.) Well now I have a virus on my computer that wont let windows start. Every time I go to turn on my computer, I get a black screen with just my mouse pointer.
So, I went looking for the disk that the guys at FRY'S gave me after they worked on my computer, and it was an MSI disk, and I booted from it, and now I'm in some OS called Winki 3 which is linux based and I don't know what I'm doing, to my surprise, I'm online.
I need to be able to get my computer working again, and I don't want to loose any of my files if I have to reinstall windows. I have a few questions before I start getting into this and try to get my computer to work but only mess it up worse.
1) What in the world is Winki 3? I've never heard of it.
2) How can I execute a .exe file? I'm trying to see if I can run my virus scan to get rid of whatever it is that is screwing with my computer.
3) I can see all my program files and everything, so I need to save some stuff on my USB's in case I do need to reinstall windows so that way I don't loose anything. How do I do that?
4) I know this isn't a place to ask windows questions, but I must. I don't have a restore disk, or a reboot disk or whatever, just this MSI disk that brought me to this Winki 3. How can I restore my computer without the restore disk, and without taking it to some place that's going to charge me an arm and a leg? There has to be some way, I mean I have this Winki 3 running, I should be able to do something that will restore the computer back to the default factory settings after I save all my files onto my USB's, right?
Security :: Address Space Randomization On 2.6.28-15-generic Ubuntu 9.04 - Finding Base Address?
Sep 14, 2009Im an academic (university networks and security lecturer) studying/teaching network and operating system security, and inspired by the work of Hovav Shacham set about testing ASLR on linux. Principley I did this by performing a brute force buffer overflow attack on Fedora 10 and Ubuntu 9. I did this by writting a little concurrent server daemon which accidently on purpose didnt do bounds checking.
I then wrote a client to send it a malicious string brute forcing guessed addresses which caused a return-to-libc to the function usleep with a parameter of 16m causing a delay of 16 seconds as laid out in [URL] Once I hit the delay I new I had found the function and could calculate delta_mmap allowing me to create a standard chained ret-to-libc attack. All of that works fine. However .... To complete my understanding I am trying establish where I can find the standard base address for ubuntu 9 (and other distros) for the following, taken from Shacham:-
Quote:
[code]....
/proc/uid/maps gives me some information but not the base address ldd also gives me the randomised starting address for sections in the user address space but neither gives me the base address. Intrestingly ... when a run ldd with aslr on for over (about) 100 times and checked the start point of libc I determined that the last 3 (least significant) hex digits were always 0's and the fist 4 (most significant) where between 0xB7D7 and 0xB7F9. To me this indicated that bits 22-31 were fixed and bits 12-21 were randomized with bits 11-0 fixed. Although even that doesnt define the boundaries observed correctly.
Note: I am replicating the attack to provide signatures to detect it using IDS, and for teaching purposes. I am NOT a hacker and if needed to could reply from my .ac.uk email address as verification.
