Hi All-- I know that the subject of this email sounds ridiculous.... but let me explain my scenario!
I am running dropbear on a Microblaze-MMU platform (Spartan-3A FPGA, running @ 62.5MHz). I've optimized things as far as I know how, but making an ssh connection to dropbear still takes about 12 seconds, and the scp and port forwarding performance is still very slow. The Microblaze platform is in a completely private environment (that is, the network access to the outside world is via another faster embedded processor within the same enclosure). Since all security can be handled from the node that is accessible to the outside.....I was wondering if it is possible to configure dropbear in an "insecure" mode, even to the point of not using encryption? I know that there are other alternatives such as rsh/rcp, but I would like to stay with the ssh method (and I may have a need for some port forwarding in the future). Has anyone had any experience with this type of configuration? I guess I should also ask: does anyone know of any way to improve the speed performance of ssh on a slow platform like the Microblaze? Our access to the Microbaze will require frequent, repeated ssh sessions, so any real delay in establishing connections isn't acceptable. Thanks for tolerating this "dumb question", and thanks in advance for any help! Steve Hein, SGI, Inc.
