Unfortunately, the HPN patch breaks the DynamicForward feature in at least OpenSSH 5.0 (see <http://gnats.netbsd.org/45049>). I'm not sure how it fares with newer versions of OpenSSH.
>From the bottom of the HPN web site (<http://www.psc.edu/networking/projects/hpn-ssh/>): Recent problems with buffer_append_space in HPN-SSH. If you are experiencing disconnects due to a failure in buffer_append_space please let us know. We're currently tracking some problems with this and we're trying to gather more information to help resolve it. You may want to try using -oHPNBufferSize=16384 to restrict the growth of the buffer. Let us know if that helps. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/162253 Title: openssh: want hpn-ssh for 20x speed improvement!
