Just in case anyone was wondering, I did some throughput testing on a test VPN I have here. It is pretty CPU intensive as far as I can tell. The VPN was running on two OpenBSD boxes with ~400 mhz cpus. See the details and gnuplots at:
http://www.ligo-la.caltech.edu/~sroddy/netpipetests/netpipe_tests.html About a factor of 20 reduction in speed when going from client->gateway->(encrypted)=>gateway=>(decrypted)->client. I am going to do some further testing on faster machines. I am also going to try blowfish vs. 3des encryption. Blowfish seems to be faster than 3des on ssh. -- Shannon Roddy __________________________________________________________________ Systems Administrator California Institute of Technology [EMAIL PROTECTED] LIGO Livingston Observatory ph: (225)686-3106 19100 LIGO Lane fx: (225)686-7189 Livingston, LA 70754 Web Page http://www.ligo-la.caltech.edu/~sroddy Calendar/Schedule See Home Page Wireless Email (255 Chars) [EMAIL PROTECTED]
