Security :: Convert One's Private Key To Id_rsa?

Apr 17, 2011

Some people have said that it's dumb to use the same key for multiple things, but for curiosity's sake, is it possible to convert one's private key to id_rsa? I know that I can convert my public key to id_rsa.pub with ``$ gpgkey2ssh [key ID] >id_rsa.pub'', and that makes me think that there should be a way to do it with my private key.

Mar 18, 2011

When you install sshd and run it with no modifications, then any other machine can connect to your machine without specifying a key. How does this work? Some key is being used, correct? how does the client know what private key to use?

Ubuntu Security :: Create Private GPG Key Server?

Jan 25, 2011

One of my clients is considering implementing GPG or a similar technology to encrypt internal emails. (They have a different system in place already for external mail.) I've done some reading on the subject but can't seem to find any information about how one might set up a keyserver. All the discussions I've seen so far talk about uploading the public keys to a server like keyserverDoes anyone know what software packages might be used to set up our own private keyserver on a Linux machine?

Ubuntu Security :: Public / Private Keys On Multiple Servers?

Mar 26, 2010

At the moment we have one SSH server with the private key being on a usb flash drive, and the public key being on the server in authorized_keys2. Now that three more servers are coming online, should we generate new keys, so we have muliple private and public keys (one pair for each server), or use the same two keys to access all the servers

Ubuntu Security :: UNABLE - Access Private Data Desktop

Oct 12, 2010

I have a seperate partition for my "/home" folder. Whenever I install a new distro I format my "/" folder.

This way I was able to access my old home data files since I install using a different username. Everything worked fine until last Sunday.

10.10, unlike other versions of ubuntu, has encrypted my old username in my home folder.

Then using this document [url]

I was able to mount my hard drive again. But all the file and folder names are like this.

Btw I don't remember selecting an option to encrypt my old home directory in the first place, what is this ?

Ubuntu Security :: Creating PPK File Using Puttygen - Private Key Not Loading

Oct 12, 2010

I am trying to use puttygen to create a ppk file that I can use with putty. I try to import the private key and it gives me the error: Couldn't load private key (ciphers other than DES-EDE3-CBC not supported). Now I obviously know this is telling me that I have the wrong cipher, but what what do I do to use the correct one? Here are the instructions that I used to create the keys.

Also, when I open the key this is the top:
- BEGIN RSA PRIVATE KEY -
Proc-Type: 4,ENCRYPTED
DEK-Info: AES-128-CBC
and then some other stuff that I don't think I should share. But the weird thing (to me atleast) is that it lists CBC right at the top there which is what puttygen wants. Why won't it accept it?

CentOS 5 :: Passwordless Ssh Login From Windows - Uploaded The Generated File Id_rsa.pub To Server

Aug 22, 2009

I have an rsync server and am now setting up cwrsync on my windows machine. I want to be able to run cwrsync over ssh with public private keys. I followed a tutorial over here to set this up. It, however, still prompts me for server password and works only if I provide the password. For some reason the public/private key process is not working.

- I generated a key using the command: ssh-keygen -t rsa -N '' (I verified the key gets generated on my Windows machine)

- I uploaded the generated file id_rsa.pub to server /root/.ssh/authorized_keys

I am also prompted for a password if from command prompt I run this command to log into server: ssh -i c:docume~1user.sshid_rsa root@<server_ip_address> On server I have changed the configuration file (/etc/ssh/ssh_config) to say:

RSAAuthentication yes
PubkeyAuthentication yes

I then restarted the sshd service, however, to no avail.

Ubuntu Security :: Snort: Convert From IDS To IPS

Feb 4, 2011

I am currently running snort as an IDS on the same machine that acts as our gateway. I installed it using sudo apt-get install snort. However, I'd like to make it run as an IPS. Is it possible to convert that currently running snort instance from running as an IDS to an IPS without having to download the snort tar balls and install it? I do not want the tar balls because during updates and upgrades, I'd like the whole OS and installed apps (such as snort) to be upgraded.

Software :: Convert A Bunch Of .ogg Files To Mp3 To Play On IPod - Unable To Convert With Sound Converter?

May 3, 2009

I have Ubuntu 9.04 and just installed Sound Converter. I am trying to convert a bunch of .ogg files to mp3 to play on my iPod and it's not working so well. In the Sound Converter options I have is set to convert to high quality mp3. I choose the folder that the files are in and after a moment (slow laptop) Sound Converter populates, I hit 'convert' and it shows that the conversion completes in two seconds. All that it did was create the new folder structure of artist/album but there is nothing in there. Not sure what I am missing. I used Sound Converter before and it worked fine.

Software :: FLAC Files To Convert Or Not To Convert To CD-DA?

Dec 24, 2010

I have a lot of .flac files downloaded from several sites. Most of them come with a .cue file, and the .jpg with the cover, etc. It seems it is the intention of the uploader that one rebuilds the original CDDA. However, if I had a stand-alone CD/DVD player with flac I would hardly see the point of converting the flac to cdda. Furthermore, I could even play the flacs with a software player although, in this case, the audio quality would not be so good due to the noise picked up by the signal from the PC digital circuits.

Ubuntu :: How To Backup 'Private Directory'

Apr 13, 2011

After an upgrade gone wrong my 9.10/10.4 is unbootable and I see no way to fix it.

I can't mount the directory now (LiveCD or chroot), it probably has something to do with the breakage and/or pre-existing ecryptfs issues, as I have both login and mount passphrases.

And it's all on one partition too, so before reinstalling I have to back up. How can I back up the encrypted directory? And can I transplant it to a fresh Ubuntu installation?

cp complains about symlinks, returning 'not permitted', is this normal?

ETA: Now that I look at it from LiveCD .ecryptfs and Private appear as broken symlinks (what do they link to anyway??), but when I tried to copy them while chrooting, they were both accessible directories (though still couldn't mount or copy) - I don't get it.
