http://www.psc.edu/networking/projects/hpn-ssh There have been some changes to the command line switches which are detailed on the website. This is more of a stop gap release than anything else. This is still in the HPN-11 cycle of patches. We hope to have an update to HPN-12 out sometime in March (when I can get some freetime). This will conform more closely to the OpenSSH nomenclature and argument structure. Basic functionality has been tested. We're still getting a 20x to 30x performance improvement for bulk data transfer on paths with high BDP. I don't think we've broken any of the new functionality but if someone does find a problem please let me know ASAP. Also, if anyone here is using the GSI patch (Grid Security Infrastructure) a new version has been released from NCSA which incorporates the HPN patch. http://www.cmu.edu/PR/releases06/060125_gsi.html and http://grid.ncsa.uiuc.edu/ssh/ Thanks!
