General :: Invalid Size Displayed For SSD?
Dec 11, 2010
I have an 80GB Intel X25-M SSD drive installed on a Linux box running Debian 5.0. The file system on the SSD is ext4. I've had no problems with the drive, and have been using it for quite some time as both swap file storage as well as a place to store a few large database files which require random access.
However, I noticed this odd size readout from ls:
> ls -lh /ssd
total 34G
-rwx------ 1 root root 23G 2010-12-11 18:00 file1.dat
-rwx------ 1 root root 22G 2010-12-11 18:00 file2.dat
I changed the names of the files here for security reasons, but other than that this is exactly what ls has output. Obviously, the total size readout is incorrect.
Here is the corresponding output from df
> df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 74G 35G 36G 50% /ssd
Despite this incorrect readout, the drive seems to be working fine, and diagnostic utilities turned up nothing wrong with the drive. Is this some sort of known bug in ext4, or is it more likely there's something physically wrong with the drive?

I have installed squid 2.6,sarge,webmin 1.5,squidguard1.3, dansguardia in a centos 5.4 version.Since I want to implement the password change option using web, i installed changepassword 0.9.Everything was working fine except the changepassword cgi. I can see the interface of change password screen and when i tried to change the password using web, it displayed "user not found or invalid.Please go back and try again." But actually there is a user with that password. My password is stored at /etc/squid/squid_passwd.I have changed the permissions to 777 .But all in vain. Where i can search for the logs?the httpd log is as follows
[Mon Jun 21 22:02:35 2010] [notice] suEXEC mechanism enabled (wrapper: /usr/sbin/suexec)

Basically, I am running diskwarrior on my mac now to try and fix invalid b-tree node size error. It is my boot drive and therefore cannot get onto the operating system. I have used live linux distros to try and get at the hdd that way, I have installed HFStools and testdisk and tried almost everything possible from within Linux itself to recover this HFS+ drive, but they were all a no go. My last resort was to try diskwarrior and it is rebuilding the drive now, well it has been for about 38 hours now but doesn't give any indication as to how long it will take.
I am pretty sure I am right in thinking data is never truly deleted until it is overwritten, is that right? Even if reformatted, would I be correct in thinking that if I were to format the drive and install linux on my machine, some of the data on the Drive would still be technically recoverable, even though the file system has changed? i.e. from HFS to EXT3. If this is technically possible what software would I need to try and recover files from a drive that has been formatted from HFS+ to EXT3?
It doesn't matter if I cant get it all, or might be more hassle than its worth, my girlfriend has another laptop to use for now and is in no hurry and I like getting to play around with Linux. The data is somewhat important but not enough so to go through the whole sending off the drive and paying hefty fees, it would be very nice to get back and I enjoy working in linux and learning more about software/hardware etc.

I installed Debian 5.03 Lenny successfully on my machine. I got this error during boot: ACPI : invalid PBLK length [5]. After that the Operating System boots properly and starts normally. What does this error statement mean? Is it safe to work with this installation despite this error?

Trying simply to insert into table. Have succeeded in doing this but now want to correct user use of invalid characters. If I'm understanding correctly, Real-escape-string seems to correct these, so I've been trying to figure out how to use it. A short, test code version gives me a syntax error at INSERT VALUES, which--because it still has the single quotes in the text--tells me the real-escape-string didn't work. The code below gives me a parseing error with invalid $END at </body>.
Insert Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' VALUES (UTC_TIMESTAMP,'What's happen' bra?')' at line 1 Parse error: syntax error, unexpected $end in /home/powere15/public_html/DB/exercises_insert_record.php on line 94

Is there a way to get Linux to log all of the output that you see on the screen at boot?
It would sure beat having to dig through all of the different log files trying to find what was seen while it was booting.

I'm programming an web system using LAMP, currently I'm using Ubuntu 10.04, so, when I load the index page the background image is not displayed, it looks like a permission file issue - I guess-, so currently all images have this permissions:
Code:
-rw-r--r--
and the permissions for the php files are:
Code:
-rwxr-xr-x
what permissions should I set to display the background image?

Having problems displaying French chars. They are dumped into an nfs share by a Windows/cifs configuration which has been blamed for this unwanted behavior but when I transfer a file continaing � via WinSCP to the RedHat, instead of getting the filename Response.txt I see R?sponse.txt. When I refresh WinSCP to view the file it views it ok.

I have linux firefox installed on my notebook, and after having a bit of a problem with it, I did a full factory reset back to all the original settings. Now when I connect to the internet, some of the pages now are not displayed properly. For instance, when visiting E-bay, the listings look fine, but my E-bay page is all listed down the page, (if that makes sense) and I cannot look at any of the photos. MSN is also, how can I put this, spread out across the page. I have done a live update to see if that makes a difference, but no joy.

I vaguely remember that there is a way to store instructions for vim in my file (like tabstop width etc). I'm not speaking of settings in vimrc but of storing those settings with in the file to be edited. That way the tabstop has always the right width even if I transfer this file to another computer. However, I can't remember what the magic word is so that vim picks up those settings when loading the file.

Got 3 computers connected by ethernet to a router modem. At this router modem only port 80 is forwarded to a web server (one of the 3 computers). Now I realized several times a port scanning attack displayed at interactive firewall of Webserver ( Apache at Mandriva LINUX ). Actually the message is port scanning attempt of heanet (actually this names are different mostly). I wonder how to figure out is this portscanning attack possible through port 80 or is the modemrouter (Draytek VIGOR) misconfigured, compromised or one of the other 2 machines (Windows) are compromised and attacking the server inside intranet?

I have a requirement related to the apache access log file format: When a user access my local site, http authentication will be displayed:
Code: username: saagar password: 123 I wish to have the LogFormat in the configuration file in such a way that the username and password (saagar/123 in this case) will be logged in the /var/log/apache2/mysite_access_log file. I used the %u parameter as follows: Code: LogFormat "%h %u "%r" %>s %b" common CustomLog /var/log/apache2/mydreamhome_access.log common and it works, similarly I wish the password too to be displayed in the access_log file.

Bottom Line: Dvd Drive died in my toshiba laptop and it was replaced (not before tech for some reason reformatted the Win7 partition... which was 100% un-needed, but thats beside the point now. I redid win7 (the tech installed vista) and am TRYING to "redo grub". Facts: The Slackware AND Ubuntu Partitions ARE STILL THERE and when i use SuperGrub Boot CD (which doesn't restore my grub by itself) to boot into slackware, i can see ALL THE CONTENT of both Linuxes still there including grub on ubuntu partition
(Tri-Boot: Ubuntu, Slackware, and WIn7) I had it working for two years or so, SO i know this "setup" works fine. I am A) Trying to do this as simply as possible. B) Trying to avoid the need to download a 800MB ISO (as seen for this issue on this forum) and trying not to have to reformat Ubuntu Partition (though I have the .Debs I have downloaded for it backed up ... all 1.7GB of them) I have /dev/sda1 as win7, /dev/sda2 as Slack and /dev/sda3 as Ubuntu (which contains Grub Legacy).. Every command I do seems to result in an error like "invalid command" or "invalid Execution format " (i think that second one is right) type errors. I compiled (awhile back) a few kernels for Slackware, but feel goofy that I cant figure what i this out (what i thought was going to be a "2 minute" fix)

How to unmount a filesystem in Linux without investigating why is it busy? I want to do it in one command. It should handle applications using that filesystem, submounts, containers (lxc-execute -n qqq <command>) and all other things.
Just "unmount. No objections!". Special kernel patches or configuration is allowed. Filesystem should be really unmounted, so umount -l is certainly not an option. For example, for cryptsetup remove (BTW how to forcibly cryptsetup remove? Update: cryptsetup luksSuspend, but you won't be able to cryptsetup luksResume if it is not LUKS). How to make all filehandles on that filesystem invalid?
The only reliable way I know is mounting the filesystem through the FUSE (there is usually no problem to unmount FUSE thing because of I can just kill it's process). P.S. Already know mount fuser, lsof | grep, cat /proc/*/mounts | grep and obsolete non-working "badfs patch".
