Hi,

We are running openvpn on a linux network. We'd like to do a true stress test to simulate our traffic at it's worst or even worse. Is there a good piece of software out there that will do a truly comprehensive stress test of out vpn setup?

Also, is TCP over/thru UDP the standard for vpn?

Stress testing?

You need to define what your system does! Then use an automailer:

http://www.sharewareconnection.com/auto-mailer.htm

A datatransfer script:

ftp something in your own script

a download script:

wget

etc.

Tweak values to match your worst envisaged case and see it it works! This is an extremely 'inexact' science, as you can guarantee that the user will do something you hadn't thought of. Just give it your best guess. Also remember:

1.    mail transportation(SMTP) is supposed to be able to cope with network problems, and will continue working again correctly once any network overload has been resolved.

2.    ftp can be made so that it can continue where it left off.

3.    web browsing disruption to the user causes complaints:)

>Also, is TCP over/thru UDP the standard for vpn?

Do you mean:

UDP over/thru TCP the standard for vpn?

In fact the answer to both is that there are numberous standards for VPNs. They have different protocols associated with them, and different ways of achieving them. openvpn is a classic example using ssl in 'userland' code rather than kernel code.

If you wished you could use UDP over UDP, and various other combinations, but it is more usual to go for a TCP layer and run UDP over it, because it's easier to tunnel through firewalls.
