Data Encryption On The Server

Mar 20, 2008

Are there solutions to sync folders between local and remote servers with file encryption capabilities. I mean:

<source server, unencrypted> <----sync-----> <remote server, encrypted>

I need sync similar to rsync, secured data transfer and encrypted storage on a remote server, so even root won't be able to access the data.

RSA Encryption Algorithm

May 11, 2009

I am just trying to understand RSA encryption.

Just say I have three parties Alice, Bob and Eve.

All parties have access to Bob's Public Key.

Alice is going to send Bob an encrypted message of either "1" or "0" (without quotes)

Eve manages to intercept Alice's message.

If Eve encrypts "1" and "0" using Bob's Public Key, will one of them be the same as Alice's encrypted message?

Email Encryption

Aug 8, 2007

I have a client that is in need of a easy to use and transparent as possible method of sending encrypted email to many external clients.

They have currently been using verisign digital ID's and have not been satisfied with the amount of work necessary to send and receive encrypted email.

I would welcome any and all installable or 3rd party service recommendations on how to handle this. The would prefer that their cleints receiving the email have to do the least amount of work, in order to receive their emails.

Cipher To Use For OpenVPN Encryption?

Jul 15, 2008

Can anyone who is a security expert recommend the most secure option for choosing what type of "cipher" to use with our OpenVPN setup?

(I bolded the one I think might be best? Let me know what you think. We are currently using "BF-CBC", but I want to be sure it's not breakable...) ...

System Updates And/or Encryption Not Typical

Aug 2, 2007

I believe there is a gap in my understanding of VPS with regards to just how much control you really have over the system. VPS gives you "root access" which typically means top-level access... but in reality, the true super user is a boot-up console user. Few VPS providers that I've investigated offer console access to your VPS while booting.

What, than, can be done about system upgrades or using advanced features like root filesystem encryption? Say, for instance, that my provider offers openSUSE 10.1 and I want 10.2. I would be loath to do such a thing if I can't reboot and watch things as it goes. What if the upgrade failed and you need to drop to a single-user mode to fix it?

Or maybe my real misunderstanding here is that you can't upgrade a system in a VPS if the provider doesn't offer the upgrade?

And what if I want my entire system (other than a boot partition) to be encrypted. This would include an encrypted root and swap. This also requires a password at bootup well before any services (like sshd) start.

Again, maybe the real answer is that I can't do that at all anyway and so it doesn't matter.

Entire Disk Encryption [Linux]

Jul 1, 2007

I'm contemplating creating a website that could store extremely sensitivity information. It's more than likely that a MySQL database would house this information.

My question is. Does anybody have any experience when it comes to encrypting an entire server disk?

I've searched online with disappointing results.

Apache :: Dev / Random For SSL Encryption Seeding On Windows

Jun 25, 2014

What's the go with seeding the PRNG on windows as there isn't dev/random or dev/urandom? Should I use CryptoAPI or just use a file with random contents and change it often, or just leave the PRNG to "almost" randomise itself?

Plesk 11.x / Linux :: Migration And Transfer Manager - Unable To Exchange Encryption Keys

Jun 20, 2014

I'm trying to migrate old server into a new server.

Both uses plesk 11.5.30 version.

I'm using the "Migration & Transfer Manager" for importing everything but it does not work. The error is

Error: launchpad error (Error code = 2):

Unable to start SSH session: Unable to exchange encryption keys

Seems like an ssh problem but ssh from shell works fine in both directions.

I tried also to create public key and put into authorized_keys with no luck..

Transferring Large Amounts Of Data From Server To Server

Jan 11, 2007

Recently I changed server providers, so now I'm looking for a way to transfer all the data to my new server. I have a total of 420GBs of files in my secondary HDD that need to be transferred.

The old server is at a 10Mbps line, the new one is at a 100Mbps one. From old server, less than half the pipe is being actively used. So theoretically, I should be able to transfer it all in about a week.

I tried
1) SCP. That was waaay too unreliable. And I couldn't get it to restart from the point left on whenever the transfer stopped (like when the servers were restarted).

2) Transfer using a web script. Way too slow, got to about 35GBs, total would take like 2 months.

Is there any other, reliable way of transferring data from server to server?

DB Server And Web Server In Different Data Centers

Nov 27, 2008

DHas anyone got experience of having a web server and db server setup where the servers are in different datacenters? Is this a viable solution or would the performance of sites suffer too much due to the added latency? The only other problem I can think of is additional bandwith usage but that's not a major worry.

Reason I ask is beacause I've found and excellent deal for a DB server and would like to keep my current server for the front end..

Physically Erasing Data From Server

May 22, 2009

I'm moving some data over to another server and I want to wipe out everything on this server that I currently am using. There is some pretty sensitive information on it and I don't really want the datacenter to erase the data themselves. Is there a way I can do this using root?

Also I gotta ask, does CentOS still archive deleted files like windows? If it does is it possible to also write a script that will fill up the hard drive with ones and zeros so that I can be certain that all the data is gone.

Retrieve Data From 2nd HDD After Server Failed

Feb 3, 2008

My server HDD got corrupted. My server provider mount a new HDD for me, and put the OLD HDD as secondary drive.

This is what they emailed me:

[root@ns1 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/hda3 149G 3.7G 138G 3% /
/dev/hda1 99M 17M 77M 19% /boot
none 498M 0 498M 0% /dev/shm
/usr/tmpDSK 485M 13M 447M 3% /tmp
/tmp 485M 13M 447M 3% /var/tmp
/dev/hdc3 149G 23G 119G 16% /backup

I have a forum data (files and database) that is still on the old HDD, I hope to retrieve it.

May I know how can I access to the data?

I tried SSH, can only go till /dev/, then don't know what to do.

What is the command in SSH that I should type in order to go to the 2nd HDD? How can I retrieve the database and files to my new HDD?

Getting Lots Of Data Off A Dedicated Server...

Nov 30, 2008

I have a project (using multiple servers) that has generated 3TB of data (compressed), with another .5TB or so each month, and the hard drives on my servers are very close to capacity.

The data doesn't need to be accessible online, so I'm trying to find a low cost way to deal with this data. Keeping the data on dedicated server(s) raises the monthly cost every few months, which isn't good. Transferring that much data to my location via the Internet is costly and inconvenient.

I'm thinking the best option would be to find a host that can ship hard drives to me, after I copy data over. Does anyone know if that is something that hosting companies are willing to do?
