General :: Secure Erase Of CF Card Over USB?
Aug 9, 2011I have a CF card I'd like to erase. My CF card reader is connected to my Linux machine via USB. How do I do a secure erase (i.e., the ATA Secure Erase functionality) of the CF card?
I have tried hdparm --security-erase NULL /dev/sdc, but I get an error: ERASE_PREPARE: Invalid exchange. In fact, any hdparm command gives me the same error:
# hdparm -I /dev/sdc
/dev/sdc:
HDIO_DRIVE_CMD(identify) failed: Invalid exchange
I read somewhere that hdparm can't do an ATA Secure Erase of a drive that is connected over USB. Is this true? I tried using sdparm, but sdparm doesn't seem to have the capability to send the ATA Secure Erase command to the CF card. So, what is the proper way to do this?
OpenSUSE Install :: ATA Secure Erase Command Working Right Now?
Oct 18, 2010I first tried to use UBCD HDDErase although it won't detect my seagate 1000 GB Sata HD (This worked for my other computer/HD). So I loaded up a OpenSUSE live cd rescue terminal to enter the command (of course after setting a password and making sure HD is not frozen):
time hdparm --user-master u --security-erase uber /dev/sda
The following line appears:
"Issuing SECURITY_ERASE Command, password="uber", user=user
That's all it says and there is no % completed or anything. (as it appears on the wiki)
https://ata.wiki.kernel.org/index.php/ATA_Secure_Erase
Also I can still type but theres no command or console or anything it just is blank if I hit enter.Is my HD being wiped right now? or is it not working?
General :: Use Hdparm To Unlock Drive?
May 25, 2010I am running Xebian on my old Xbox. Currently I am trying to fit an old hdd that is locked (to a mo-bo that has expired). I have connected it up instead of the dvd drive and booted with it as slave. The OS can access it using hdparm -I /dev/hdb, but it showing as locked I have the key which is:
HDDLockDisablePassword 76 1d d3 2b e9 df 17 96 64 3b 5c 5f d9 95 ba 4e 74 f5 e5 0e 00 00 00 00 00 00 00 00 00 00 00 00
I am trying to input this using hdparm I have tried:
hdparm --security-mode U --security-unlock 761dd32be9df1796643b5c5fd995ba4e74f5e50e000000000000000000000000 /dev/hdb
which doesn't work. What format does the password need to be in. I suspect ASCII but I can't type some of the characters. Is the rest of the syntax correct? EDIT I have another key:
XboxHDKey d0 f3 f9 9a 03 20 41 b7 a4 70 bd eb 1b b3 cc ac
Should I be using this one?

Nov 22, 2010Assume I have a computer on which I want to use ubuntu for a while (single boot). Assume also that in about six months I want to give this computer to Mr. X, but I do not want Mr. X to know that I have been using ubuntu. I don't want to install anything over top of ubuntu, I just want the computer to be completely (or as nearly completely as possible) blank so that Mr. X cannot infer what I've been doing on it. The trick here is that I can't use operating system x_{1} to delete operating system x_{0}. I don't want Mr. X to know anything about which OS I have been using. Mr. X, by the way, is a sophisticated computer user but not particularly interested in tracking me down. Once he sees that the computer is blank Mr. X will just install his own operating system and everybody will be happy.

Security :: Ways To Secure Sendmail Or Secure Alternatives To Send Mail
Dec 1, 2010I'm an Oracle DBA and started working for my current employer about 4 months ago. This past weekend an alert re: FS space brought my attention to /var/spool/clientmqueue (full of mail re: cron jobs) and the fact that sendmail is not running on our Linux servers.I'm told that the IT security team deemed sendmail too vulnerable so we don't run it.Aside from FS filling up and missing notification of issues with crontab entries, I'm concerned that we may be missing notification of potential issues. In other Unix/Linux environments I've seen emails from the print daemon when it experienced problems with specific jobs.
Are there other Linux facilities aside from cron and lpd that use email to advise the users of possible issues? Are there ways to secure sendmail or secure alternatives to sendmail? My primary need/desire is to make sure that emails regarding issues on the server get to the appropriate users. Secondary goal would be to have the ability to use mailx to send mail out. There is No need/desire to receive mail from outside.

Ubuntu :: How To Compile The New Hdparm
Apr 19, 2010I've been using ubuntu for the past year now but unfortunately I have to confess I never had to compile anything from scratch. I bought a new intel SSD drive and I've been running some benchmarks on it with various fs. The new hdparm version has a few features that I'd like to test (TRIM/wiper) but I don't know how to install it as it's not in the repositories. I've been googling for almost 4hrs now but I still haven't found a way to do it.
I've downloaded the tar.gz file from sourceforge and I've decompressed it. Inside, it was a debian folder but there was no .deb file in it. Anyway I did a "make hdparm" and it compiled with no errors. It gave me an "hdparm" executable which works fine if I call it with the full path. what's the proper way to install it in place of the already apt-get installed package?
Ubuntu :: Hdparm Not Putting HDD's To Sleep?
Dec 12, 2010Im wanting to put HDD's to sleep using hdparm after 20min of activity (a 4x disk raid5 array and two single disks). I have edited /etc/hdparm.conf, adding the following lines at the end of the file:
Code:
#6TB RAID5 POWER DOWN
/dev/disk/by-id/scsi-SATA_ST32000542AS_5XW0T1R6 {
spindown_time = 240
[code]....
Code:
sudo hdparm -y /dev/disk/by-id/scsi-SATA_SAMSUNG_HD501LJS0MUJDWQ411622
The HDD's will sleep with out issue. Ive looked around my log files and cant seem to find anything to do with hdparm, or the HDD's sleeping. Have I make a mistake in the .conf file? Is there some place hdparm logs, or if I can activate some sort of verbose mode? Or does hdparm need to be activated on boot?
EDIT: I'm using ubuntu 10.04.1 x64 last updated today.

Applications :: Hdparm LSI Controller Support - Invalid Argument
Jan 7, 2010I have SSDs connect to my Linux machine through the LSI SAS/SATA 1068E controller. I've been trying to issue a ATA secure erase command to my SSDs, but I keep getting error. In fact even hdparm -i fails.
# hdparm -i /dev/sda
/dev/sda:
HDIO_DRIVE_CMD(identify) failed: Invalid exchange
HDIO_GET_IDENTITY failed: Invalid argument
Initially I thought there was some kernel configuration issue, so I tried connecting a SSD to the on board SATA and I no longer get errors. The secure erase worked. It seems there is some compatibility issue with hdparm and the LSI controller/driver I'm using. Any way to make hdparm play nice with my LSI controller? Has anyone had success getting hdparm to work with drives connected to an LSI controller?
Additianal info:
Linux Kernel: 2.6.30
hdparm: v9.27
LSI driver: Fusion MPT SAS Host driver 3.04.07
Debian Hardware :: Persistent Hdparm Setting After Wake From Sleep
Jan 26, 2016I have set up a hdparm configuration file ( /etc/udev/rules.d/50-hdparm.rules ) with :
Code: Select allACTION=="add", SUBSYSTEM=="block", KERNEL=="sda", RUN+="/usr/bin/hdparm -B 255 -S 0 /dev/sda" .
This works correct when I power on my system, however after waking my computer from sleep mode , /dev/sda appears to operate with APM .
Is there a way I can make this setting to be persistent ,i.e. APM disabled when waking up from sleep mode?
I am running Debian Jessie x64.
Ubuntu Servers :: Hdparm Won't Put Drives To Sleep After Specific Time
Feb 17, 2011I've just put together a 10.04 server using a GA-D525TUD atom board. I've installed gnome desktop too. I'm trying to get 4 sata drives to go into standby, but hdparm seems to be ignoring the settings. If i issue hdparm -y /dev/sdx the drive duly goes into standby and stays in standby until accessed. I've put entries in rc.local along with the hdparm.conf settings, but still no joy.
Hdparm.conf:
/dev/sdb {
spindown_time = 244
}

Hardware :: Media Server Disk Consumption And Hdparm Configuration?
Oct 13, 2010I have some general question with with quite an impact for the system I use I have a media server with 2 raid1 mirrors of 2 1 To disk aggregated with lvm and used by a big 2 To ext3 partition.A few days ago, munin (awesome!) started to send me notifications about smart attributes of some disks. Fyi, here's my hdparm.conf:
/dev/sda {
spindown_time = 54
}
/dev/sdb {
[code]...
regarding reliability and disk longevity, is it recommended to have them spin down while not used (most of the day, as these are storage unit for movies, pictures, documents..) or let them spin whatever.. ? Those are WD green and according to Tom' Hardware, the consumption is only slightly greater in idle compared to standby. The other question, (boat one as we say in french ) what is the best configuration here ? My 2 raid 1 stripes, or a raid 5 ? I know that two disks kill the raid 5, and they have to be of the same stripe to kill the lvm on the raid1, but what are the odds ?
CentOS 5 Hardware :: Hdparm Misbehaves With ICH7 SATA Drives?

/dev/sda:
setting fs readahead to 256
setting 32-bit IO_support flag to 1
[code]....
Note that setting most of the parameters fails - and it still appears to be in 16 bit PIO mode. Am I using the wrong tool here - or incorrect parameters - or are the results misleading? Is there some other interpretation?
Debian Hardware :: Can Hdparm's Readahead Setting Mess Up IDE Hard Drive?
Sep 10, 2011On a Powerbook G4, I set hdparm to set the filesystem readahead (-a) to the maximum 2048 on boot. This produces a visible increase in performance... But today the hard drive started acting up - first generating I/O errors when trying to access various system binaries, and the second time bringing the desktop to a standstill and emitting loud clunking noises.In both cases the drive worked normally after a reboot... Even so, these are not what I'd consider good signs. However, the computer was working perfectly up until now, so I'm wondering if my tweaking was responsible. Can overly aggressive filesystem readahead settings damage an IDE hard drive?

Jul 16, 2010I'm testing OpenSUSE 11.3 on a server and I'd like to disable the write cache on all of my drives. In Ubuntu Server I was able to accomplish this with hdparm by adding the appropriate settings to /etc/hdparm.conf
As far as I can find the only thing that OpenSUSE offers is /etc/sysconfig/ide which allows you to force particular DMA modes. I could just put the hdparm commands in /etc/init.d/boot.local but I'd prefer to do it the right way if there is a right way to do this in OpenSUSE.

View 3 Replies View RelatedGeneral :: How To Properly Secure Computer
Apr 21, 2011there are different methods for securing based on home versus professional computers. My questions generally pertains to securing home desktops, but professional protection is definitely welcome :) Knowledge is power. Ever since moving to the wonderful world of Linux a couple years ago, I never even really thought about security. Seeing as most low-life scum make viruses for Windows machines seeing as they're more abundant.But how do I know if I'm safe/secure from anyone who want's to get at me or my stuff. I know that anyone who is determined enough to get in will, there's no question about that. But what steps can I take to ensure I'm protected from things like rogue root shells and automatic attacks? Also, is there a sort of built-in firewall/antivirus in more Linux distros?
I know this question is quite broad seeing as there are tons of ways someone could compromise your system, but maybe you could share what you did to make sure you were safe.I decided to not allow root login via ssh and to change the port is listens on to something random. Hopefully this a step in the right direction. Currently looking at iptables and shutting down services.
General :: Secure Screenlocking With X And Tty Login
Aug 14, 2011I choose not to run a login manager on my systems, instead opting for a tty login and then invoking xinit manually (slightly long story, it makes my life a lot easier to have a bunch of environment tweaks that my login shell sets up and has the rest inherit), but this leaves me with a security issue if someone else comes upon my PC, because even if I've locked my X session they can switch to a tty and kill my X session, dropping back to a shell.
I can either
Start running xinit; logout (which still has a race condition issue, if they get another Ctrl+C in before logout is invoked it'll give a shell) Try to disable the tty switching keys in X Wrap xinit in something to catch and ignore the signal from the Ctrl+C
