I was wondering what is the different between SSL certificate from verisign,
http://www.verisign.com/ssl/buy-ssl-certificates/compare-ssl-certificates/index.html
which is expensive , and a certificate from godady which is cheap though,
http://www.godaddy.com/ssl/ssl-certificates.aspx
is it like more secure or browser compatible ? they both generate a public/private and certificate keys ?
Thanks
Alaa
It's all about trust. Verisign is a more highly-regarded authority than GoDaddy, so they command a higher price. Furthermore, Verisign verify the legitimacy of your organisation, whereas GoDaddy are only verifying your ownership of the domain.

We are setting up an ikev2 client vpn using strongswan. So far we have managed to setup a single server using letsencrypt certificate with eap-radius authentication method. We are able to connect to our server without any issue. Now we want to auto-scale the vpn so that the server gets scaled up or down depending on the number of users connected to the server but how do we do it?
What would be the best approach to achieve this?

I want to see plain xml text of xmpp messages content for developing , debugging ,etc
so I've installed 'ejabberd' as xmpp server and 'empathy' as xmpp client.(i track packets with wireshark)
i think it should be done by changing configuration in xmpp server , but i don't know how ?!
I would like someone to guide me through disabling encryption and see xmpp request in plain text form in wireshark.
Thanks in advance!
In ejabberd.cfg, in the listen section, look for configurations for ejabberd_c2s.
Comment out the lines specifying the the certificate and starttls support.
Without starttls, no encryption will be offered (you might need to confirm on your client that you want to connect without encryption as some clients prevents that by default).

We are setting up a link to a client and they wish to use SFTP but without using keys for client authentication, just passwords. Do you still get the benefit of data encryption with this setup? I thought the protocol used the client keys for encryption but does it or can it use the host key instead?
EDIT:
Looks like Wikipedia has what I needed to know: "SSH also supports password-based authentication that is encrypted by automatically generated keys." (http://en.wikipedia.org/wiki/Secure_Shell#Key_management). And yes not entirely a programming question but a bit of a reflex reaction for me to ask other developers.
Yes. There's a difference between the transport-layer key exchange and the user-authentication key exchange. You do not need to generate any client key pairs for password authentication; authentication happens over an encrypted tunnel negotiated by the transport-layer key exchange, which is largely transparent to the user.

I want to connect ubuntu virtual boxes with each other on a network. I want to use hadoop on it. So i need to put them in a network. It requires ssh to communicate. Can anyone help regarding it.
The easiest way is to change your adapter to "Bridged networking" instead of "Nat", the default. This way the guest system will get an ip on your local network and you can connect directly to it.

If I push to Bitbucket like this:
C:\My Projects\repo>hg push https://user:passd#bitbucket.org/user/repo/
pushing to https://user:***#bitbucket.org/user/repo/
searching for changes
no changes found
The first line is what I type:
C:\My Projects\repo>hg push https://user:pass#bitbucket.org/user/repo/
But the message from Mercurial hides the typed password:
pushing to https://user:***#bitbucket.org/user/repo/
Does that mean my password is encrypted before it goes out over the public WiFi connection and is therefore safe?
If it uses SSL then it should be encrypted before password is sent. Whether mercurial uses it or not is specified in mercurial web server configuration.
push_ssl
Whether to require that inbound pushes be transported over SSL to prevent password sniffing. Default is True.
