Ubuntu Security :: How To Upgrade BIOS In 10.10
May 22, 2011
I have established that there is a BIOS virus in this machine (I have basically done every test that can be done) And I found the flashing utility for upgading and everything, now the only problem left is installing it Whenever I try this happens.....
Code:
./BIOSUpdate/FTS_FlashBIOSUpdateLinuxBootDisk_500110_1005782.SH
Flash FirstBIOS Update Diskette
V5.00 R1.10.2164.A1
[code]....
Now I did that while logged in as root....
sudo ./BIOSUpdate/FTS_FlashBIOSUpdateLinuxBootDisk_500110_1005782.SH
I also tried above command logged in as root and the 'normal' admin account. the usage instructions that I obtained from the manufacturer are: The BIOS Update File is a .sh file (Shell Script), which enables you to create a bootable disk to update the BIOS.The script only works if there is a C-Compiler installed at usr/bin/cc and the user has write access on dev/fd0 (e.g. if not filed as Root).

I just have a simple BIOS password when I boot into my machine. Should I also have the standard login password as well? In other words, what benefit does the login at the boot up, (after BIOS) really give and would you recommend a good or better security process?

I recently set up a Clonezilla server as I have 200+ computers to reimage. Everything was setup and working fine, until I ran into a computer that has a newer BIOS. Grub loads and works fine, but the kernel hangs.
Specs:
Server: Dell OptiPlex 740
Ubuntu 10.10 Desktop x32, kernel 2.6.35-30 generic
Clonezilla version: 2.3.8-32
[code]...
So as mentioned above when I boot the client from PXE to image it, Grub loads, and as it tries to boot, the following lines appear:
Loading vmlinuz-pxe....
Loading initrd-pxe.img.....ready.
Probing EDD (edd=off to disable)....ok
[screen flickers then returns to the above text. Freezes.]
I updated the bios on a machine that previously worked to confirm/replicate the problem. How do I fix this?

I reinstalled XP to do a dualboot with 10.10 yesterday. All was fine. Today I went through and installed everything windows needed, and everything seemed fine. Then I upgraded the BIOS on my motherboard, and suddenly everything isn't fine. I can boot to Ubuntu just fine. But when I select Windows from the GRUB menu, it just sits there with a cursor on the screen now.

Still in 8.04 hardy heron, ordinary upgrade via automatic upgrade does not work, some essential pieces missing, but also my bios does not support usb cd and my "original" cd drive is broken. So........ I have burnt a cd Ubuntu 10.04 Lucid Lynx desktop version
32 bit (intel).
1) I have broken cd drive and old bios, i have usb cd drive instead which is not supported by bios when boot from cd.
2) I have still Ubuntu 8.04 Hardy Heron but if i upgrade to 10.04 from there via automatic upgrade, this does not work, some patches missing, whatever, but upgrade this way does not work and in the end the system is set back to 8.04 again...
3) I have burnt a cd with entire Ubuntu 10.04 Lucid Lynx which i had downloaded from the web at ubuntu com; within my 8.04 i want to install all of it, so i want to install 10.04 this way, so a fresh installation via my usb cd (this is also the way i had burnt this cd image; the cd shows all the files so it is the right way burnt), so just not via bios boot, or how to explain this best.

I'm attempting to upgrade the BIOS in an ASUS 1005HA netbook. The netbook runs SuSE 11.3, and no other OS. All the BIOS utilities on from ASUS are Windows or DOS based. ASUS has a utility titled afudos that apparently flashes the programmable ROM. Running afudos using the dosemu utility suggests that one needs to create a DOS boot drive, execute afudos during a reboot with the new ROM image located on the drive.
How does one accomplish said task on a netbook without a floppy disc drive? Do I create a bootable DOS USB flash drive that contains just afudos and the new bios flash rom upgrade? And if so, how does one do this? As a side issue, it looks like all the major motherboard vendors do not support Linux. That is, all the motherboard drivers require Windows or DOS.

I have a dell inspiron 530 desktop with core 2 quad and 4GB memory, running 32bit vista and 64 bit fedora 10. I searched on the web with "can I install 8GB memory on dell inspiron 530", and got couple of articles that says I only needed a bios upgrade.I downloaded bios version 1.0.18 from dell and run that in Windows to replace bios 1.0.12.After it said upgrade successful and asked me whether I wanted to reboot to have the new bios taking effect, and I said yes. And it shutdown the computer, and never came up Now, when power up, I see nothing, not even the "F2 to setup, F12 to boot menu" message, much less the grub selection. Is there a way to revive the computer?

I have some virtual machines running with CentOS 5.3 (32 bit) and everything works as expected. To test a possible upgrade I took one of then and did yum clean all yum update after rebooting I get a kernel panic with the following message:
MP BIOS BUG : 8254 timer not connected to APIC IO I know that I can change the boot command not to use APIC and after that the machine boots again but I doubt that there has been any change to the virtual APIC implementation during the upgrade of the OS. Is there anything that iI should exclude from upgrading while working in a vm? I use VMWare Player 2.5.3 build-185404 on a 64 bit Ubuntu 9.04 as host.

I can get into the BIOS just fine but cannot find anything such as NX or Exucute Disable mode( on or off) Does anyone have any ideas? I contacted Acer support and they may be able to help only if I pay for their support. AS of now I have Ubuntu 10.4 installed and upgraded to 10.10 but have black screen with message about (NX) or Execute Disable in bios. The message says---This CPU is family 6, model 37, and has NX capabilities but is unable to use these protective features because the BIOS is configured to disable the capability. Please enable this in your BIOS. I have windows 7 professional on one partition and Ubuntu on the other partition. I can still access Ubuntu 10.4. but have the black screen on 10.10

I recently upgraded to Ubuntu 10.10. This was a clean install, so all packages are up to date.
I'm using Thunderbird 3.1.6 with Enigmail 1.1.2.
Thunderbird works OK, but if I try to create an encrypted message, I get an error saying that the Enigmime module is not available. When I checked the Enigmail 'About Open PGP' details, it showed the following message:
Running Enigmail version 1.1.2 (20100630-0917)
Warning: Enigmime module not available
ERROR: Failed to access Enigmime service!

what a horrendous piece of software. Ive been at it 3 days trying to do something that ought to be simple and everytime i solve one problem another problem arises. at first I removed the old clamav 9.5 or something. I got the latest ubuntu release btw, and Clamav used to work when i first installed it in the previous ubuntu release. anyway, it asked me to upgrade, so since synaptic doesnt have the latest, i downloaded from sourceforge. I did the whole ./configure gave me errors like need build-essentials-- which i then did, error: need zlib.dv--- I did that one too. Now two more errors that i need to fix so I can compile it.

I setup a remote web server yesterday evening, which had Centos 5.3 on it. This went well, and I did this mostly over vnc, to get a GUI. However, I hadn't realised that there was a pending cron job to 'yum upgrade'. So, come 2am, 5.3 turned into 5.6. I carried on the install today, but after some time (I'm not sure exactly how or when), I lost the ability to run any GUI system config tools that required root login. I also lost the ability to run anything graphical - emacs, for example, when I was already root in an xterm.
/var/log/secure isn't telling me anything. It claims that it's running the config tool on my behalf, but nothing happens. If I try to run emacs, I get a message saying that the X server isn't responding. Could this be related to the upgrade? It feels like a PolicyKit problem - I've seen something similar on 6.0 for remote access over vnc - but 5.6 isn't running PolicyKIt.

I have a fiberoptic broadband 20MB synchronous pipe at my home. Over summer at my place of employment its pretty much dead for 3 months so when I'm not busy I play around on my home server. I have my 20mb pipe going directly into my wrt54gl, from there I have a wired connection going to my server (Centos 5.3 recently upgraded to 5.5 through updates.) It serves as a file server(Samba, SSH). My wrt54gl handles natting port 22 to my server. I have my wireless AP setup to hand out leases from .2-.20 and my server has a static of .100. Dyndns.org handles my name resolution via their free account method.
I have a Mac Pro, iMac, Macbook, and a Toshiba Laptop with 64bit 7 running off wireless along with our cell phones, and my XBOX 360 also is wired directly for the gaming speed. I use all of the computers around my home to access the samba shares via unc path for file sharing and or working on projects. I had originally planned to upgrade the wrt54gl with a cisco e3200 or an e3000 but unfortunately I've come to find out dyndns and the e lines of cisco wireless AP's dont work with dyndns and get banned. So I would have to install the daemon on my server and put it as a directly connected server to my WAN link and install a second ethernet card and pass traffic through my server for the rest of my home which I am not going to do.
All of the previous sentence because it would update dyndns with a 192.168.x.x address since its not directly connected. I use a combination of putty.exe and vnc viewer to tunnel 5900 through port 22 to my server. So from anywhere I am at I can access my screen securely and then rdp or vnc to the desktop of my local LAN computers. This allows me to only have port 22 open. I've been looking at my ssh logs and noticed I have been getting hit alot with ssh scans. I want to implement an iptables firewall on my linux machine just for the purpose of further securing port 22. I dont necessarily need natting on the iptables firewall but all I need is ssh in and out, web in, and samba out to local ip's only.
For SSH this is what I want. I want to allow SSH from any IP but if it tries to login more than 3 times in one minute I want to block that IP for a full minute before it can try 3 more attempts. I also would like log to a file but have been having issues getting that to work as well. That way when I review logs and I see that an ip tries three times and then waits a minute and tries three more, etc... I can permanently block that ip or range of ip's by adding it to the iptables script. Here is my current iptables script and it doesnt seem to be working for me. I have played with this and read for almost two weeks and still cannot get it to work correctly.
Code:
#!/bin/bash
# In order to use this iptables firewall script you must have iptables installed. You also must be using a 2.4.x series Kernel, with iptables suppport compiled into it, which is standard for most newer linux distributions.
# If you need help compiling iptables into your kernel, please see our kernel Compile/Upgrade Guide located at [URL]
# Once the script has been edited with all your relevant information (IP's Network Interfaces, etc..) simply make the script executable and run it as root.
# chmod 700 fw_rules.sh
# ./fw_rules.sh .....
# Our final trap. Everything on INPUT goes to the dropwall
# So we don't get silent drops.
$IPT -A INPUT -j dropwall

Today I ran
aptitude update && aptitude safe-upgrade
Like I regularly do, and I see these two packages need to be upgraded:
login passwd
Since these packages seem kinda security-sensitive I would like to know exactly why I would need to upgrade them. I checked Debian's security list but couldn't find anything relevant, and the links to the changelog for both packages are broken:
The requested URL /changelogs/pool/main/s/shadow/shadow_4.1.4.2+svn3283-2+squeeze1/changelog was not found on this server.
Where can I see what is changed in these packages so I can safely upgrade?

when i got my starling netbook 6 months ago it worked perfectly. due to upgrades since then i now have problems with printing, sound and videos. there are probably solutions to all of these things if i spent hours here on the forum asking questions, and trying different solutions, but it seems like a lot of work.
upgrade manager calls these things "important security upgrades". are they really important to security? would my computer be dangerously vulnerable to attack if i never did an upgrade?

A day ago I finally got around to upgrading the PackageKit installation that had been sitting for a week and a half, so I found a new upgrade for sudo available - the one that gives the sudoreplay command, I forget which version number it is exactly. When I try to use the sudo command I get this notice in my terminal:Code:Can't open /var/db/sudo/me/1: Permission deniedI didn't get it before. What do I have to do to make it open? I'm using SELinux in enforcing mode if that helps.

I keep getting the following msg as I try to upgrade from 10.04 -> 10.10 ... "Could not calculate the upgrade An unresolvable problem occurred while calculating the upgrade: E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages. This can be caused by:
* Upgrading to a pre-release version of Ubuntu
* Running the current pre-release version of Ubuntu
* Unofficial software packages not provided by Ubuntu
If none of this applies, then please report this bug against the 'update-manager' package and include the files in /var/log/dist-upgrade/ in the bug report." I don't think any of the issues above apply - can anyone offer advice on how to get around or "force " the upgrade

I'm trying to do a test run of 10.04 LTS with a cd but the machine isn't booting from the cd ( or two other subsequent cds that I know work). I thought I remembered not having to do anything to make this boot from a cd, so either something has changed or I've flipped out. Once it boots 9.04 from the hard drive it recognizes that there is a program cd in there though. I've tried F8, F10, F12 and ESC - ESC nets me a list of drives to start from Ubuntu 9.04 and several versions of recovery mode also a command line. I'm baffled - this is probably something simple but its beyond me at this point.

I have a Dell XPS 600, and absolutely no working OS is installed on the machine. By that, I mean I have WinXP, but there's some error and when I run a normal boot it loads Windows Setup, but it "encounters" an error. Not that I care, I just want Ubuntu. So basically, I need to setup Ubuntu without first running an operating system. But my BIOS won't load it- I press F12 at startup and select "boot from onboard CD drive" but then it tells me that there's nothing to startup from, and I get stuck pressing F2 to retry. Btw, I used the regular 10.04 disk download, not the live CD.

I made a bootable usb drive that I would like to test on my sony viao laptop. I cannot seem to figure out how to get into the bios so I could set it to boot from the usb. I tried pressing F10 and F12 while booting but these were all guesses as I do not know which key combination is used to go to bios on this machine.

I have installed Ubuntu 10.10 Minimal on a 2GB USB using CLI and it is working very well after adding a few applications. But this USB will be used only on machines other than my own - likely with Windows as the only OS. And it is not comfortable for me to go into the BIOS of a strange machine to change the order of booting and afterwards go back to reset the order , especially with the owner looking on, obviously worried, and wandering whether his machine will still be working!
So my question: Is there any way to boot from a USB without having to go into the BIOS? code...
