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?
View 2 RepliesHas anyone worked in building p2p apps and protocols? I'm talking an actual p2p network of physical devices that is strictly p2p, no servers for most things. Are there security and privacy benefits to p2p? How are addresses handled, like say you want to send a message to a specific friend but you don't have the relatively static IP system in the Internet. How are those things handled?

Few lines under the command it says:"Because the user is required only for ownership purposes, not login purposes, the useradd command uses the -r option to create a user that does not have login permissions to your server host."What would be the benefits if mysql user has not login permission?

Code:
./BIOSUpdate/FTS_FlashBIOSUpdateLinuxBootDisk_500110_1005782.SH
Flash FirstBIOS Update Diskette

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've got two laptops running Ubuntu. Both have had Lucid installed from the live cd. I have upgraded one of them to Maverick. Both distributions are running great after they boot up, but I haven't experienced any faster boot times with either distibution. Both boot to Bios and then the screen goes black with a blinking cursor in upper left corner of the screen. The black screen remains for 30 to 45 seconds and then I get the Ubuntu splash screen for maybe 5 seconds, and then desktop. Why am I not seeing faster boot times? I realize 45 to 60 seconds is good compared to other os's, but I anticipated much faster boot times. Shut down on the other hand is quite fast at maybe 5 to 10 seconds. Does anyone else get this black screen on boot? Seems like wasted time cause I can't tell what's going on during the time there is a black screen. This is not a real big deal breaker, as I don't reboot very often, but I just wonder why bootup isn't faster.
View 7 Replies View RelatedWell today I decided that I couldn't wait for the offical release of 10.04 LTS, so I upgraded from 9.10 to 10.04 LTS Beta 2. After realizing that many problems had come with that update, I decided to just format my Ubuntu partition and reinstall it. Somehow my GRUB stopped working from when I formatted Ubuntu, so I whipped out the old Toshiba recovery disk for Windows Vista 32bit. After many attempts to have the recovery portion of the disk fix all of my problems and seeing no results, I decided that reinstalling Ubuntu (and GRUB) might make everything all better. Well it didn't. Grub shows my Windows partition but fails to boot it. After selecting it, it goes to a blank screen and stops responding. And to add to all of my problems, my BIOS has changed slightly. It no longer shows/or responds to F2 or F12 when I tried to give another try at that Toshiba recovery disk. That kinda sucks since I can't choose what to boot. Please help me!! I really don't want to have to format my entire hard drive and try to install Windows Vista again (Not that Vista is anything anyone should love) I have many expensive programs that can only be activated a certain amount of times. I don't even think that I could reinstall Vista since my BIOS won't let me boot the CD/DVD drive.

I'm seeing really bad user login format under a standard installation and am wondering why ubuntu does this as default. I have noticed that the graphical login for gnome sizes itself to accommodate a user's exact password length. This indicates to me that somewhere on the unencrypted part of a standard installation with user encryption contains at least some indication of the content of the password length which seems a security flaw even if not a complete hole, it majorly reduces the number of attempts a cracker would have to cycle through.
And that's assuming that *only* the length is contained. Furthermore it seems that it would be MUCH better to simply display the number of characters entered into the pw field and allowing the gui to expand itself from an fixed size as the field is filled out so the the user still receives visual feedback for entering characters. Either a simple character count display should be entered into the field or a 10 dot to new line so that one can visually quickly count the number enter by multiplying from a 10base graphical observation.
just migrated to Lucid from Jaunty and noticed that the login startup screen looks more like windoze (shows all authorized users).One of the endearing security checks with Unix was that if you had access to a console you had guess both userid AND password - the system wouldn't tell you which was wrong.I feel that we have lowered security by making the list of authorized users visible on a console. Is there any way to turn it off and force users to enter both userid and password?

View 9 Replies View RelatedI 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...
im on an old (8 years?) hp that doesnt support booting from usb. will a bios upgrade change that?
View 1 Replies View RelatedI understand this is not directly an ubuntu issue, but this arose as I was trying to install ubuntu, so I'm hoping some kind souls on here would be good enough to help anyway.
I've in the past installed ubuntu on to my PC using a CD, but this time I thought I'd try creating a USB startup disk.
I was required to set up the BIOS to change the boot order so I can boot from the USB flash drive.
The problems arose when I pushed the 'DEL' key (the correct key for my motherboard) to access the BIOS setup. When doing this the computer completely froze and would not progress any further to boot. It would still boot normally from the HDD provided I didn't try to enter the BIOS.
Looking on the internet for a solution I tried using the motherboard jumper to reset the CMOS. Now I can't boot up the computer at all. I get a message saying 'CMOS checksum error - Defaults loaded' then it asks me to press F1 to continue. I try this, but nothing happens. Clearing the CMOS has made things worse as now I can't get the computer to boot at all.
Have I killed my motherboard somehow? I've tried using a different keyboard (one USB and the other a USB keyboard but with an adaptor to connect it to the P/S2 port).
On further investigation any key press from the keyboard is enough to freeze the computer at whatever point.
My motherboard is an WinFast NF4SK8AA with AMD Athlon processor and 4Gb of mem.

View 2 Replies View RelatedI was wondering to restore on old laptop to working order. This laptop is an old early 2000's Sony Viao, which I found in the trash. Still powers on, and can boot the latest Ubuntu LiveCD. The issue is that it did not have a harddrive in it, and I really do not want to shell out money for a drive for a laptop this old, but would still like to bring it back into service as a thin client or general purpose web/email terminal. The BIOS does NOT have a USB boot option, and every tutorial I have seen requires that in order to boot Ubuntu from a USB stick (which is what I do have). What I am wondering is, is there any way to just keep the LiveCD in the drive and use that to boot the kernel, etc, and then have it look for the rest of the filesystem on the USB stick?

The trouble is I cannot get to the bios in order to boot from the USB and it says on the box (in very small print) that users cannot install other OSes then the pre-installed Windows CE. Windows CE wont run the Wubi so I can't install ubuntu on it either. How can I bypass these incoviences and get Debian up and running.

View 6 Replies View RelatedLong story short, I changed these BIOS settings (and changed them back), but now Ubuntu won't boot: SATA RAID/AHCI Mode: from Disabled to AHCI
Onboard SATA/IDE Ctlr Mode: from IDE to AHCIThe last thing it says is "Init: ureadahead-other main process (nnn) terminated with status 4". Booting off an Ubuntu CD and entering Rescue mode gets me to a shell; the file systems are still there, but Reward for first solution (other than reload): $10 Starbucks card!
So I installed Ubuntu 8.04 with Wubi a while ago on my Toshiba Satellite A500/02j and recently uninstalled it (with Wubi). For whatever reason, Windows will not get rid of its bootloader and I cannot access my BIOS settings. I've tried spamming every function key that I have when it boots up but nothing happens (if I press ESCAPE when I'm at the boot menu it restarts). Any idea on how to get rid of it and get me my bios back?
