Slackware :: WARNING: Prelink Not Found, Base Address Of Core Dlls Won't Be Set Correctly
Mar 4, 2011
i installed slackware current straight(make iso from it and installed on clean disk) and i installed Multilib current from alien and now when i wanna compile wine source its write
"configure: OpenCL 32-bit development files not found, OpenCL won't be supported.
configure: libsane 32-bit development files not found, scanners won't be supported.
configure: gstreamer-0.10 base plugins 32-bit development files not found, gstreamer support disabled
[code].....
I checked i got that libaries in /lib and /lib64 why it doesent work it was working on slackware 13.1 with multilib

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 searched around and found this thread: [URL], and that appears to be the same issue. Although, I don't quite understand how to fix it.

When I installed Wicd, and ran it for the first time, I got an error something like: "Could not connect to Wicd's dbus session- check the Wicd log file for more info". However, later when I restarted my computer, Wicd started, but I can't connect to my network, it shows up as <hidden>, I can connect to linksys, so I know that wireless is working on that computer. I know that there's nothing wrong with my wireless router, because I can connect to my network in this computer.

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 experienced this problem on Friday but didn't have time to write a warning.A couple of days ago, xserver-xorg-core 2:1.10.2-1+b1 reached Testing before a corresponding dependency (recommendation), thus breaking the hardware acceleration. The issue is (better) described here (1) by a developer.A possible solution is to keep (2) the previous version (2:1.10.2-1) or, if you already installed the faulty one, to grab the former version from Debian Snapshots (3) and downgrade the package.Because the error was a simple path change, one could also keep the new version of xserver-xorg-core and link the DRI Mesa modules to the directories that are inspected now (as described here [4]).The issue has already been addressed (5) and a new version should appear in Testing shortly.[URL]

I'm fairly new to Linux so I'm going to need a step-by-step guide to get me out of this rut. The install of Linux was fine but when I booted up I got this error. VFS: Cannot open root device "302" or unknown-block (3,2) append a correct "root=" boot option;here are the available partitions;
0800 78150744 sda driver:sd
0801 47428608 sda1 <-- this is my Windows partition
0802 30719552 sda2 <-- this is my Linux partition
0b00 1048575 sr0 driver:sr
0b01 1048575 sr1 driver:sr
Kernel panic - not syncing:VFS:Unable to mount root fs on unknown-block (3,2) I guessed from reading this error Lilo isn't pointing to the right partition to boot from? How will I fix this? I read another thread about boot problems on these forums and a guy said to do this:
#mkdir /slacktemp
#mount /dev/device /slacktemp
#chroot /slacktemp
#cd /slacktemp/etc <-- for me it told me that doesn't exist
#vi lilo.conf <-- couldn't do nothing and was frozen
#lilo -v -t -b /dev/device
#lilo -v -b /dev/device
The above solution did not work for me. Can anyone shed a light on a Linux rookie?

I have a display problem since updating to Slackware 13.37. Everything was fine on Slackware 13.1, but when I switched to 13.37 some piece of software came up with the wrong monitor size. I have a 1600x900 LCD monitor but the X screen came up as 1024x768 with blackness on either side of it. Under Slackware 13.1 the X screen came up as 1600x900 as it should without any prompting from me; I didn't even have an Xorg.conf file. I tried using the Xorg.conf file which was needed and work for older Slackwares, eg 12.*, but it didn't work. (Saying it didn't work is a gross understatement! That old Xorg.conf completely screwed up mouse, keyboard, and monitor; the screen was flashing and nothing worked. The only way to get control back was to SSH into the machine from my laptop and reboot. Killing the X server via that SSH console did NOT the flashing or get me back to my console login; only reboot worked.)
I find I can get the screen to be the right size manually by going through KDE's "System Settings" --> "Display and Monitor" --> "Size & Orientation", then disabling "LVDS1" and setting VGA1 to 1600x900. The size of my odd-sized monitor is being correctly detected for the "Auto" choice. Upon reboot LVDS1 stays disabled but VGA1 reverts to 1024x768 so I have to do this each time.I've done some search of the on-line literature regarding the error messages I am seeing in the boot log.
People are suggesting changing all kinds of things to alleviate the side effects of the "conflicting" error message above, even modifying GRUB parameters (which won't work for me since I use LILO).So, I have a manual work around which I must do each time I log in. Does someone know how I can get X or KDE to force 1600x900 upon start (while Linux/X/whoever find and fix the problem) or does someone know of a real fix?

Currently I am running Ubuntu 9.04 on my computer, and it is the only OS installed. I purchased the $30 student WIn7 Professional upgrade. I have a XP Pro CD + Key, and I plan on using that just to upgrade to Win7. I love Ubuntu and it is my primary OS, it is just that every now and then you come across some program that requires windows (Propellerhead Reason 4, Adobe Photoshop CS4, Atomix Virtual DJ etc.) and it requires full system resorces so you do not want to use wine. I love Linux, but somtimes I just have to use WIndows, so I do not want to hear any arguments about that.
I want to do a clean install of everything, and I have data + programs backed up, I would like to install Ubuntu 9.10, WinXP Pro and I want to Upgrade XP Pro to 7. I am completely new to GRUB 2, and upgrading windows; but I have experience with Linux and Windows, and dual booting. I would like to install Ubuntu 9.10 on its own partition (No WUBI), and WInXP + Win 7 on there own partitions (3 Partitions Overall). I would like to know what to do at this point, Should I install Ubuntu then Xp then 7, Xp then 7 then Ubuntu, etc. I know how to make Partitions, I just need to know the order in which I should install the operating systems, and how to get it to dual boot.
MY COMPUTER:
I had a Sony Vaio PCV-RS530G, and the mobo failed, so I rebuilt it, the case, processor, fans, CD/Floppy drives, TV tuner and power supply are unchanged, everyhing else has been replaced, here is the breakdown:
Proecessor: Intel Pentium 4 3.20 GHZ, HT Technology, No 64-Bit or VT-x
Motherboard: Biostar P4M900-M4
Hard Disk Drive: Seagate 1TB SATA (IDE Mode, no RAID)
Graphics Card: Nvidia GeForce 8400 GS, PCI Express, 512 MB RAM
RAM: 2 GB Corsair, DDR2-5300
1) How can I install all the screen savers that were in Jaunty, but are missing in karmic?
2) Can Win7 be installed without a key, and then have the key entered later (I AM NOT PIRATING, I JUST WANT TO PUT THE KEY IN AND ACTIVATE AFTER I CAN TEST OUT EVERYTHING AND MAKE SURE THAT WINDOWS AND UBUNTU ARE RUNNING SMOOTHLY)
3) Will XP mode in Win7 work on a processor without virtualization technology?
4) I have Icon sets, cursors, window borders, and panel backgrounds from different sources, can I export this as a complete theme in 1 file (Deb Packages are preferable, but even a tar-ball is fine) so I can install it easily on more machines, and share it with friends?
5) How do you use native windows DLLs in WINE?
6) My PC has a tv tuner, how do I use it in Ubuntu?
7) What is a good size for a swap partition for my computer (Detailed information below)?

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?

Is it possible to get a list of packages installed on the system that are not a part of Slackware (i.e. take all installed on system, take all packages that originally come with slack, find difference)? Worthy to mention is that I use slackpkg and run -current.

I'm interested in changing the console text color. I can change the console color easily in X, but I'd also like to change the color of the text when my computer first boots up (like right after LILO).Is this something I can modify without rebuilding the kernel? If not, does anyone know where in the source I could make a change like this?

I installed it via Wubi it did well, but when it told me to restart, I did, after restarting I booted Ubuntu Netbook, then it said "Installation.iso not found. This usually happens when your computer does not shutdown correctly, shutdown without unmounting/removing usb. Please run the chkdsk /r" I already ran that many times nothing happens. I have Windows XP Pro 32bit.

I'm having some problems getting the GUI installed in my Server 10.04 installation.
I've installed the Ubuntu server 10.04 32bit with a VMWare player on a Windows XP Pro host. Everything seems to have gone ok but at the end of the install it said that VMWare items are being installed and while that happens I can only use the terminal mode or I could wait for the GUI to load. Well the GUI never loaded so I logged in through the terminal.
I realized immediately that I'm over my head as I'm more familiar with DOS rather than bash or the terminal commands of Ubuntu. So I tried to look up on the internet (from my host machine) on how to start or install the GUI interface for the server. I've found lots of things that show commands like:
sudo apt-get install gnome gdm
or
sudo aptitude install gnome-core
but in all cases I get a message that the package is not found. So I'm wondering how do I find the package so that I can install this?

I am trying to compile and install a new kernel. I have downloaded the 2.6.37 version from kernel.org and I have extracted it in usr/src/linux-2.6.37/ folder.I have tried to compile it and install it according to the instruction given in the following web site and which I found very useful:ttp://www.digitalhermit.com/linux/K...WTO.html#INTRONevertheless, I am encountering some problems during the make install modules process as I get some warnings (i.e. The title of this post).I thought to ignore the warnings and continue by copying the modules in /lib/modules/linux-2.6.37 but this is not possible since at that directory there is no folder created with the new kernel I am trying to install and thus I get a msg saying: FATAL: could not load /lib/modules/2.6.37/modules.dep.
The warning message: WARNING: modpost: found X section mismatch(es) suggests to run a make CONFIG_DEBUG_SECTION_MISMATCH=y.At the moment I am running a make again and saving the output to a file so that I can see later on what are the mismatches that I get. In any case we are talking about more than 50 mismatches so I am wondering if these mismatches are not that serious and the problem I cannot install and copy the modules is something else

I am using webmin for my daily tasks. I have fedora 13, whenever I click on ''Sendmail M4 Configuration'' or Outgoing Addresses (generics)'' I get the following error message
Quote:
The Sendmail M4 configuration base directory /usr/share/sendmail-cf was not found on your system, or is not the correct directory. Maybe it has not been installed (common for packaged installs of Sendmail), or the module config is incorrect. I read documentation at sendmail.org, it seems that structure of directories for send mail has been changed in version sendmail-8.1.4 shipped with FC13. In webmin config module we have
Quote:
Sendmail M4 base directory = /usr/share/sendmail-cf
which is not there. I did a locate / sendmail-cf on the command line, it finds nothing

I just installed madwifi on my MSI laptop with an Atheros AR5001 wifi card & Lucid. As far as I can see and according to System -> Administration -> Hardware drivers the install was successful and the card + driver is up and running. However, I don't see any wireless network (my windows PC can see about 5 wireless networks). I tried it with the network manager applet as well as with wicd. If I try to connect to "Hidden Wireless Network" via nm-applet, it will start to connect for a while but is unable too (although I supply it with the correct WEP settings & key) So, I'm unable to use my wireless network. What am i doing wrong?
Some information about my system:
iwconfig
Code:
lo no wireless extensions.
eth0 no wireless extensions.
wifi0 no wireless extensions.
ath0 IEEE 802.11g ESSID:""
Mode:Managed Frequency:2.437 GHz Access Point: Not-Associated

I've been at this for hours now, also tried ndiswrapper and ath5k drivers with no luck
