General :: Smartcards For Storing Gpg/ssh Keys?

Apr 14, 2010

I'm interested in storing my SSH keys and gpg keys on a smartcard for added security. However, I'm a bit uncertain on a few points, which are as follows:

How many keys can I get on a card? I assume both SSH and GPG can store keys on the card. Is there a limit to key size? I see a lot of cards saying they support 2048-bit keys, what about larger sizes? Hardware: can anyone recommend a card/reader combination that works well? I've done a fair amount of research and it seems PC/SC readers can be a bit iffy - is this your experience? Have I missed anything I should be asking? Are there any other hurdles?

I'm aware fsf europe give away cards with membership - I'm not sure I want to join, but... are these cards any good?

General :: F3 - F5 Keys Incorrectly Behaving As Audio Keys / Remap Them To Original Meaning?

Apr 17, 2010

I don't know if this is a configuration issue or a hardware issue, but I have a Kinesis Advantage USB keyboard and for some reason the F3-F5 keys aren't responding as they used to. They don't respond to anything and, when I tried using F5 on Emacs, it said <XF86AudioNext> is undefined, so I guess it's a weird mapping problem.

Any idea how I could remap them to the original meaning?

General :: Re-mapping Non-standard Keys To Modifier Keys?

Apr 7, 2011

I'm running Debian (Squeeze) and I have a toshiba portege m700. It has five buttons on the front just under the screen, which are the only ones accessible when you flip the screen over into tablet mode. One of them is for rotating the screen, and another is for switching to external display. I want to remap the remaining three to control, alt and super so that I can use shortcuts with the stylusThe problem is, when I used showkey to find out the key codes, I found out that each button generates more than one key code:Button 1:

key 126 press >> super_r, although this is distinct from the actual super key (125)
key 7 press >> 6
key 7 release
key 126 release

General :: Storing A Variable In A Shell Script After Awk Output?

Feb 8, 2010

On command line I have no problem storing a variable e.g


:~/bin$ process=`ps -ef | awk ' $8 == "idesk" { print $2 }'`
:~/bin$ echo $process

When I try to incorporate this into a shell script I get a blank.


:~/bin$ cat process_idesk
process=`ps -ef | awk ' $8 == "idesk" { print $2 }'`


The process_idesk script has been chmoded to be executable by the user. I'm sure there must be a silly omission on my behalf.

General :: Best Filesystem Choices For NFS Storing VMware Disk Images?

May 17, 2010

Currently we use an iSCSI SAN as storage for several VMware ESXi servers. I am investigating the use of an NFS target on a Linux server for additional virtual machines. I am also open to the idea of using an alternative operating system (like OpenSolaris) if it will provide significant advantages.What Linux-based filesystem favours very large contiguous files (like VMware's disk images)? Alternatively, how have people found ZFS on OpenSolaris for this kind of workload?

General :: Way To Prevent Network Manager From Storing Password For Wireless Network

Sep 27, 2010

Our corporate wireless network uses continuously changing passwords with RSA tokens.So every time we need to connect to the wireless we need to enter a new password off the RSA token. For extra fun using the wrong password a couple of times in a row causes the users account to be locked.Network manager automatically stores and reuses the password, with the net result that it is constant getting my account locked.Is there some way to prevent it from storing my password for that network?

General :: Bash: Calculating In Array And Storing Result In Array?

Dec 2, 2010

I have an array called arrayini which stores numbers. I want to take log to the base 2 of each of the numbers in that array and put it in file called result. I've used the following code to do it.


for ((i=0;i<size;i++))
echo "scale = 12; l(${arrayini[$i]})/l(2)" | bc -l
done >result

It works fine but its taking pretty long to calculate since I've got about 230,000 items in the array. So I decided to store the result into an array hoping that it'd be faster. I tried the following code. arrayresult is where I try and store the result. The code doesn't work because of the second last line.


unset arrayresult
for ((i=0;i<size;i++))
arrayresult[$i]="scale = 12; l(${arrayini[$i]})/l(2)" | bc -l
done >FILE2

There is a syntax error clearly.

OpenSUSE :: Kmail Not Storing The Passwords?

Apr 5, 2011

In my recently installed openSUSE 11.4 system I am using Kwallet to store all of my private passwords and also those associated with my Kmail accounts. All of these passwords appear correctly in Kwallet, but it seems there is a problem with Kmail accessing them.Whenever I start a new session, Kmail loads first and is followed by Kwallet. When Kmail then tries to do its first mail retrieval it stops and asks for the account password. I type this in and then Kwallet requests its administrator password. Once I type this in, my mail is downloaded and I get no further request for the passwords during that session.

The same thing happens when I attempt to send my first email of the day. I get a Kmail request for the SMTP account password. I've tried changing the Kwallet settings so that it doesn't close when unused for a period,or when the screensaver kicks in, but this (predictably) has no effect. In the Access Control screen, both KDE Wallet Manager and Kontact are shown as 'Always Allow' and I can see no other settings in either Kwallet or Kmail which are relevant to the problem.My guess is that the problem occurs because Kmail starts up ahead of Kwallet and therefore doesn't load the passwords initially. But that may be a red herring as I'm not familiar with the way Kmail and Kwallet interact.

Programming :: Python: Storing A Matrix For Later Use?

Apr 30, 2010

I'm writing a command-line flash card program in Python. I've tried many existing applications, but none fit my specialized needs.

All of the words I'd like to study are manually added to a text file (study.txt). Each time the software is loaded, it checks for new words in that file and also compares them to a dictionary (a tab-separated file, dictionary.txt), and adds that to a matrix. The flash cards are thus automatically generated from study.txt and dictionary.txt.

Now, the software must manage lots of information about each word I'd like to study and add new information made while interacting with the program (such as when that word should be studied next).

That seems easy to put into a matrix. But what is the best way to put that information in a place where I can pull it back when I run the software tomorrow? Do I need to save the matrix to a CSV file, then convert the CSV file back to a matrix the next time the application is run?

Programming :: Storing Numbers In QByteArray?

Dec 15, 2010

I have a program that sends QByteArray datagrams over a udp socket. I would like to have 4 bytes of the datagram that contain a 32 bit integer. When saving numbers to the QByteArray, I have tried the static function number(int) and member function setNum(int), but they convert the integer to its decimal string representation and save that in the byte array. So if the number were 10, it takes 2 bytes, if it were 10,000,000 it takes 8 bytes. This wastes space, and makes it more difficult to get the number when it is packed with a few other pieces of data in the same datagram. Is there a standard way of doing this in Qt?

Fedora Security :: Tweaks For Storing Information In Ram?

Nov 19, 2010

I've been looking for a tweak that would allow me to store temp and log files in ram. I've found a few that involved editing the fstab file, but they were either Ubuntu articles or they were over a year old and perhaps didn't apply to Fedora 14.I hear there is also a 'noatime' command that can help speed up processes by telling the kernel not to saved when files are accessed.And what are the advantages and disadvantages of noatime, and writing log/tmp files to ram?

Programming :: Parsing And Storing Multiple Values Using 'awk'?

Jan 24, 2011

I have a variable in which the data is stored as below:

variable_test=0m0.001s 0m0.001s 0m0.001s 0m0.001s 0m0.001s 0m0.001s so on.

There are lots of values in format like "3m1.057s" are stored in variable_test separated with an space between two such values. For exapmple, value is "3m1.057s" I need to save different parts of a value in three separate array variables such as the

var_sec= 057

tell if this can be done using "awk". A "WHILE" loop might be used to separate and store theses values I guess?

Fedora Security :: KWallet Not Storing Gmail's Password?

Aug 26, 2011

This used to work in Fedora < 15. Whenever I want to send an e-mail using Gmail's SMTP server for the first time in a given session, the KWallet system asks if I would not rather migrate the password and store it encrypted inside a wallet. Every time I concur and every time an error message pops-up, as soon as I try and send another e-mail. The attached snapshot shows the error message I get. It doesn't matter how many times I select "Store Password". Every time the ordeal is the same. Up to Fedora 14 this method worked all right, but now it fails.

I've accidentally deleted some files and now am trying to recover them using Photorec. I've created a separate partition to copy the recovered files to (3GB). When I run Photorec it only stores the first 5 files or so (totalling about 200Kb) and then stops reporting "no free space on the disk, select another destination". I've tried selecting my 2GB pendrive as the target storing place, but got the same error message.

Programming :: Create A ZIP In Perl Without Storing Path Information?

Mar 1, 2010

I have the following code snippet:


my $file = 'test/mybigfile';
my $zip = Archive::Zip->new();
my $zipped = $zip->addFile($file);


it simply takes a file (in this case, "mybigfile") and creates a ZIP file containing that file only. Now, my problem is that when I go to decompress the ZIP file, it creates the relative (or absolute, depending on case) path of the original file. To make an example:


$ pwd
$ ls -R


What I need is *not* to store the path information inside of the ZIP file, so that once I decompress the ZIP file I only get the original one without having paths created.
