Ubuntu Security :: Md5 In Terminal Hashes Differently Than PHP?
Jan 16, 2010
I'm trying to generate MD5 hashtext within gnome-terminal that will match that generated by PHP running on a live web server. However, when I hash the same text I get completely different results!
Code:
<?php md5('testing123') ?> ===> 7f2ababa423061c509f4923dd04b6cf1
bash$ echo 'testing123' | openssl md5 ===> bad9425ff652b1bd52b49720abecf0ba
Could this be a character set problem? My terminal is running UTF-8, but even if I change it to ISO-8859-1, the hashtext that's generated is the same. Also tried using md5sum with a text file, saved in various character encodings, but still got the same [wrong] hashtext. I'm running Ubuntu 9.10, tried running the local hash in both gnome-terminal 2.28.1 and the CTRL+ALT+F1 console.

I'm currently running tests on my SAM file on my XP partition. Partly because I want a password that is hard to crack, and also out of curiosity. While running John the Ripper (no options used) I'm noticing that there are 8 pasword hashes, yet only 4 users associated with WinXP. I know that JTR only does 7(?) characters when it check for a solution. Is the 8 hashes because it separates passwords longer than 7 into 2 hashes, and then cracks them individually as 2 parts? I did try googling this,

Why does on some computers my terminal window have a background I can see through and on others its a solid color? I have Ubuntu 10.04 installed on 4 machines as base OS and I have many virtual machines of it also. I havent changed the terminal preferences on any of them, however on some computers the terminal background which is purple is not solid in that you can see what is in the background behind it. On others the background is truly solid purple; you can not see behind/through it.
Is there any way to change the terminal window for these machines that are displaying solid to the 'see-thru' way? Ive been using some ebooks and things and really like opening up vi/vim in the purple see-thru window that allows me to write and see the text in the background...however on some machines I can not do this because the terminal display is truly solid. ? All my computers have the same profile settings for terminal..
color = use system theme
background = Solid color
Note - I am making a distinction here between what I call see-thru and the 'transparent' setting in the terminal preferences as this seems to use the desktop background and is different from what I am talking here.

The /etc/shadow file contains an id of $1$, $2$, $5$ or $6$ to show the encryption method used.A salt follows this,followed by the password hash.When a user is created and a password is set, a hash is RANDOMLY generated and used as the salt to the password hash. Everytime that user logs in, login checks /etc/shadow for the $id$ and salt and runs the password given by the user through the hash mechanism ($id$) using the salt in /etc/shadow.So basically does login look at /etc/shadow for the $id$ and salt to create a hash with which to compare to the /etc/shadow hash?question 2 - If my $id$ was $5$, which is sha256, how would i go about changing this? Like is there a shadow.conf or crypt.conf or something? Can i change it per user?

I've been trying to write php or perl code to generate the sha-512 password hashes in fedora. I've been unable to do the hashing which is encoded in the shadow file on fedora core 11. Does anyone have php or perl code which provides the hashing algorithm. (All of my attempts result in the encrypted hashing being longer than 86 character -- the length that crypt says the sha-512 should be)

Now I tried installing the KDE destop enviremont, the install went just fine but when I try to log into KDE I see the startup screen for a second then everything goes dark.It stays that way in the background i think the desktop is there because the mouse cursor is there, I can move it around but that's all.Does KDE work differently and so can the different xserver be the cause of KDE not working?

I have plugins for viewing pdf files in both Opera and Firefox. Most pdf files opens embedded in the browser, just as I want. But there is some pdf files I am prompted to save before I can open, just as if the pdf is not recognized as a pdf ? A closer look shows that this pdf's are made using pdf-printers, drawing programs and other non-Adobe programs. It probably misses some Mime coding or other things that Adobe distiller puts into native pdf's ? How can I make the browser/system/plugin/acroread only care about the extension, and not the creator ?

I'm trying to replicate the behavior of the sha1sum executable in some java code, however, in the process I've discovered that sha1sum appears to behave differently given the same input in two scenarios.
Assume input of '12345' without the single quotes and with no newline.
If I put this data into a file (file1) and run sha1sum from the command line:
However, if I do this, I get a different result:
Using the apache commons-codec jar, I'm able to read in file1, get it's contents, and perform a .shahex() on the content and get the first result. However, I need to get the second result (due to legacy code) and I can't figure out why sha1sum is behaving differently, or what grep is doing to the input.
The system is running CentOS 5.4 with sha1sum 5.97

Some time ago I optimised my fonts following dugan's great tutorial. I mostly used Seamonkey to browse so I didn't notice the difference until today I ran Firefox. The font preferences seem to be identical, yet the fonts look differently on each browser. See the attachments (the browser on the left-hand side is Seamonkey)

{
foreach my $role(sort {$trans{$key}{$a} cmp $trans{$key}{$b}} keys %{$trans{$key}})

I'm trying to figure out how to code for this specific type of instance - I want to use a hash and have the key be a reference to an array, and not use the key in the standard way of it being a scalar. Basically, I have a large output that I need to process line by line, and rather have access to it as an array than a big block in a scalar. For the big block hash as a scalar I would do -
Code:
foreach $CONTROLLER (<CONTROLLER_LIST>) {
$ALL_DISKS{$CONTROLLER} = `ssh -n <commands>`;
}
Now I know I could take the scalar and split it to another array after the fact like -
Code:
@TEMP_HOLD = split (/s+/,$ALL_DISKS{$CONTROLLER});
How would I code it that I would have access to the key information as an array and not a scalar? I know it needs to be a pointer and we're going to have -> in there somewhere, but not sure how to approach it. Some of the documentaiton I've been reading about referencing I've found a little confusing so far, and trying to figure out how to use them in context of what I'm working on.

So I ran a software in both KDE and Gnome respectively and it seems both of them have separate displays. By that I mean, one is displaying a part of the string(a Label) and the other is not displaying the string at all. I will include some relevant information such as the software uses SWT kit. Also the string is displayed perfect in Windows. If it's still not clear I will sum it up in a sentence. I am trying to display a label using SWT kit and, its being displayed correctly on Windows,partially correct on KDE(Half of the string) and not displayed on Gnome.
I have tried GridDat.grabExcessHorizontalSpace=true, but it didn't. how to approach the problem otherwise?

I have an initscript that behaves slightly differently in the UK than it does in the US. Not a huge issue, but I'd like to know why and how to fix it. I imagine it has something to do with localization, but I'm at a loss as to what it could be, as it's just bash.
in the UK:
Code:
[root@server ~]# /etc/init.d/worker

I wanted to write a script which would check the hash-sums of all files within a certain directory and compare them with previous hashes. I remembered that rkhunter does this by default for certain files. So my idea was to use rkhunter for this task. I copied the default configuration file and made some modifications to it. However, I just cannot get it to work. It always just computes the hashes for files in /bin /usr/bin etc. But I would like to also check the files, e.g. in /boot. Is there any way to configure rkhunter to compute and store hashes for *normal* (i.e. non-executable) files?

I have a file which looks something like this:
##########
some
text
text also includes empty lines
##########
some
more
text
##########
Basically all sections are separated by 10 hashes and I need to somehow only print all lines in the last section (the "some more text" part in the example above"). I tried all kind of things with sed and awk but I didn't find any way to identify the last "section".

I am in need of some syntax help. I'm trying to figure out how to store and retrieve an array out of a hash of hashes. For this example, I'm trying to access the city list for a particular state for a particular country. I understand I could do a join and split on the hash key to combine Country and State, but trying to keep things separated.The code I have gets in all the information for the Countries, and states, and gets the list of cities together, no problem. I store all the city names in an array, then make an anonymous pointer to the array for the hash, like this - $MY_CITIES{$COUNTRY}{$STATE} = [@CITIES]I believe that syntax is correct, or is it? What I'd like to do is I need to cycle through every hash to find if a city exists or not. If it exists in 3 states, then it should print 3 times. Here is the code block to search -
Code:
for $COUNTRY (@LIST_OF_COUNTRIES) {
for $STATE ( keys %MY_CITIES{$COUNTRY){$STATE} ) {

I am making a backup on an ntfs disk, mounted with:
using the following command:
Running this (or rather the shell script containing it) from the command line is OK, but if I run it as a cron job, I get thousands of messages:
(without line breaks, actually).
These files are all ordinary files made under Windows; the above should read "offici�le stukken", and from the command line it does, but not in cron.
I guess I need to set an environment variable, but which one?

The terminal does not let me enter PASSWORD (or anything else) for SUDO prompt. My password still works to boot up and for syntactic. Surely changing terminal background color from purple to green did not cause this.
While trying to find an Open Office document I stupidly lost, I meandered around to LOST & FOUND "You (me) are not the owner, so you can not change these permissions. Does this relate to password problem?

I recently set up a family computer for a friend, and now his son is "experimenting" with the terminal (randomly entering commands). since he could accidentally do something bad, I am supposed to prevent him from using terminals, but only as hi user. I tried vlock and away, but with vlock it says 'this terminal is not a virtual console', and away can't seem to lock all consoles.

I've done some searching on googlubuntu for and answer to this but haven't found anything.
As a Linux newbie I was wondering if there are certain types of output from the terminal I should beware of posting for everyone to see? Also are there any codes; that, if I were to be asked to run and report the output on, should raise a red flag?
