I am using preupgrade to update Fedora 9 -> Fedora 12 following these steps: -
Code:
yum -y update
yum clean all
yum install preupgrade
preupgrade-cli
preupgrade-cli "<FEDORA VERSION>"
reboot
I successfully upgraded this box from Fedora 6 => Fedora 9 and I guess I got too confident when this worked without a hitch and went straight from Fedora 9 => Fedora 12. Everything works up until the very end of the upgrade process when I get this error.
Code:
(process:2227): GLib-WARNING **: GError set over the top of a previous GError or uninitialized memory. This indicates a bug in someone's code. You must ensure an error is NULL before it's set. The overwriting error message was: Parsing primary.xml error: Couldn't find end of Start Tag rpm:entry line 15303

Im 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.

I have debian squeeze (and a bit of sid, actually). I wanted to install the newest pidgin, so I added at sources.list the sid repository, and tried to install pidgin, but it needed the newest perl-base 5.12.3-6 (from 5.10.1-17). So I let it upgrade. after that I realized that my mysql server isn't running, and actually this is my problem. So I tried reinstalling it, home:/home/amalia# apt-get install mysql-server-5.1.

I installed it the standard way using emerge/portage, but it fails to start:
Code:
alpha skyer # /etc/init.d/apache2 start
* Caching service dependencies ... [ ok ]
* Starting apache2 ...
apache2: apr_sockaddr_info_get() failed for alpha
apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName [ !! ]
* ERROR: apache2 failed to start
I'm used to have Apache unable to find pc's FQDN, as I don't set it, and it works without it.
From /var/log/apache2/error.log
Code:
[Sat Jul 23 06:41:12 2011] [alert] (EAI 2)Name or service not known: mod_unique_id: unable to find IPv4 address of "alpha"
Computer has IPv4 address set. I suspect that the nature of the problem is in the fact, that alpha has two network interfaces (it is used as router also). I've checked Apache conf files, but didn't find any meaningful directives to set interface or something similar.

In order to upgrade a machine that can not successfully upgrade to 10.4 I downloaded and burned the 10.04.1 iso image off the ubuntu alternate download site. In my first attempt I unsuccessfully burned the image with it failing at the very end. I did perform an md5sum on it and received the precise output I got from my second burn attenpt which DID complete successfully. Here is the output:
[code]...
I did research this last night and it seems the common wisdom was to reburn the iso (which I did twice) or copy down the iso again. This I also did and it came down precisely, bit for bit, the same as the first one. Here are the two cksums
[code]...
Is there something wrong with this image on the website or is the error about 1 file being unreadable (could that also mean missing?) be erroneous?

I am trying to understand working of pci_resource_start function So I browsed code via cscope and searched for string pci_resource_start and got following in pci.h
Code:
#define pci_resource_start(dev, bar) ((dev)->resource[(bar)].start)
I am not able to understand how does this above macro works. How does it above macro gets appropriate base address register in configuration space?

I installed F15 Xfce and now I keep getting the following message after i login: Could not loop up internet address for WXZ. This will prevent Xfce from operating correctly. It may be possible to correct the problem by adding WXZ to the /etc/hosts on your system. I tried a fresh install just to see if I did something wrong but I keep getting the same message.

I am trying to use a ZTE AC2726 USB EVDO Modem on openSuSE Linux 11.3 Gnome to connect to the internet. I have edited the /etc/wvdial.conf file as follows:
[Dialer Defaults]
Modem = /dev/ttyUSB0
Baud = 57600
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = .....
When I execute the wvdial command on the terminal the following error appears
joey-suse:~ # wvdial
--> WvDial: Internet dialer version 1.60
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: ATZ
ATZ
OK .....
The /etc/resolv.conf file has the DNS addresses as below
nameserver 212.49.70.22
nameserver 212.49.70.23
How do I resolve this and connect to the internet?

I'm new to linux, have been somewhat of a computer geek my whole life and thought it about time that I delved into the world of linux. So I installed ubuntu 10.04 on my computer. I love it. However, I can't get my wireless to work. In my dorms there are no ethernet hookups, so I have to use the wireless. I typed "sudo lshw -class network" into the root terminal. The important things that I figured out was the bus info: pci@0000:4:06.0 and the pysical id: 6 (not sure if the physical id is important but it sounds like it is). I then did a lspci and found that at bus 04:06.0 it is a RaLink Device 3060. I downloaded the .tar file for the driver. I could not find instructions for it online so I followed the ones for the rt2860 driver : [URL].... I could not get it to work, It built ok and installed ok, but when I do the modprobe I get an error saying the device or resource is busy. Either that or that it cannot be found. One thing that I found weird was that I couldn't get it to build a 3060 driver, it would only build a 3562 one.
