Changing default key size for DH Params to 2048 bit

I would suggest as a matter of security that a default install of OpenVPN through Amahi generate 2048 bit Diffie-Hellmann parameters instead of 1024 bit parameters. I say this because the NSA has said 1024 bit would only be good through 2010 whereas 2048 bit would be good until 2030. 2048 bit is muc...

Re: After changing ciphers in config file, VPN stops working

I thought of that. I just thought that it would be nice to use the most secure ciphers around. Thanks for the reply!

After changing ciphers in config file, VPN stops working.

I have added cipher AES-256-CBC and auth SHA512 to the bottom of both my server configuration file (/etc/openvpn/openvpn.conf) and to my client configuration file (/Library/Application Support/Tunnelblick/Configurations/MyHDA.conf (while on my mac)) or (/programfiles(x86)/HomeHDA/HomeHDA.conf (while...

Re: Need Help Changing OpenVPN to 2048 Bit RSA from 1024 Bit

So I would run openssl dhparam -out dh2048.pem 2048 from Terminal and it would replace the existing 1024 bit Diffie-Hellman parameters to 2048 bit? I would not need to move anything to another file location or make a change in the openvpn.conf file in /etc/openvpn ?

Need Help Changing OpenVPN to 2048 Bit RSA from 1024 Bit RSA

I wanted to change OpenVPN to 2048 Bit RSA from 1024 Bit RSA. I noticed "Control Channel: TLSv1, cipher TLSv1/SSLv3 DHE-RSA-AES256-SHA, 1024 bit RSA" in my log and I know that 2048 bit is more secure and just about as fast. I was wondering how to do this with OpenVPN through Amahi. I use Ubuntu 12.0...
