similar to: HPN-SSH for OpenSSH 4.4p1 Available

[NB: General information regarding HPN-SSH can be found at http://www.psc.edu/networking/projects/hpn-ssh ] This is a beta release of HPN12 but I'd like to get some user experiences with it if anyone is so inclined. This version of the HPN patch more closely conforms to the openssh nomenclature and coding style, it eliminates the use of command line switches in favor of -o options, it

The HPN patch set has been updated to work with OpenSSH4.6. This patch can help improve performance of bulk data transfers when using SSH, SCP, or SFTP. Please see http://www.psc.edu/networking/projects/hpn-ssh for more information. The patch is available from the above address or directly with http://www.psc.edu/networking/projects/hpn-ssh/openssh-4.6p1-hpn12v16.diff.gz If you have any

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

Howdy, As a note, we now have HPN patch for OpenSSH 4.2 at http://www.psc.edu/networking/projects/hpn-ssh/ Its still part of the last set of patches (HPN11) so there aren't any additional changes in the code. It patches, configures, compiles, and passes make tests without a problem. I've not done extensive testing for this version of openssh but I don't foresee any problems. I

HPN-SSH is a set of high performance patches which add dynamic window sizing, none cipher switching, enhanced server logging, and a multi-threaded cipher implementation to OpenSSH. We've just updated the patches to the OpenSSH 4.9 release and made them available from http://www.psc.edu/networking/projects/hpn-ssh/ Comments, questions, and criticisms are always welcome. Thanks for your

Howdy, It's been a while since I've made an announcement here but I wanted to mention that we've just released a set of HPN-SSH patches for OpenSSH6.2. The release marks the first time I've had the resources/help to actually do anything more than just forward port the patches in quite a while. http://www.psc.edu/index.php/hpn-ssh Items of note: 1) The multithreaded AES-CTR

The HPN12 patch available from http://www.psc.edu/networking/projects/hpn-ssh addresses performance issues with bulk data transfer over high bandwidth delay paths. By adjusting internal flow control buffers to better fit the outstanding data capacity of the path significant improvements in bulk data throughput performance are achieved. In other words, transfers over the internet are a lot

Just so you know the HPN-SSH patch for 4.5p1 has been released at http://www.psc.edu/networking/projects/hpn-ssh The 4.4p1 patch also works against 4.5p1. The 4.5p1 patch just addresses some line moves for a cleaner patch.

Ben Bennett and I (both researchers at the Pittsburgh Supercomputing Center) have released the HPN13v1 patch set for OpenSSH 4.7p1. Primarily this release incorporates the previously announced multi-threaded AES-CTR mode cipher which will allow users to make better use of multi-core environments. In our test environments we've seen upwards of a 100% improvement in throughput performance

Hello Are there plans to merge the hpn-ssh (http://www.psc.edu/networking/projects/hpn-ssh/) and the LPK (http://code.google.com/p/openssh-lpk/) into the mainline openssh. Adding lpk has been logged as a bug in bugzilla as They are two patches that I always apply as the performance boost from hpn-ssh is substantial to say the least, and centralisation of the authorized_keys into a LDAP server

Hi, http://www.psc.edu/networking/projects/hpn-ssh/ Clearly, the HPN patches significantly boost throughput performance. This enhancement is entirely from tuning the SSH buffer sizes. Alex Tavcar

We've released a new HPN (High Performance Network) patch for OpenSSH 3.9p1. We've made two major changes - first off we backed out of all the modifications we made to buffer.c. Turns out that it just wasn't necessary once we fixed a nagging bug in channels.c. I also made a minor change to the buffer sizes in the source and sink functions in scp.c Increasing the size of both

The HPN-SSH patch set for OpenSSH 4.7 is now available from http://www.psc.edu/networking/projects/hpn-ssh/openssh-4.7p1-hpn12v18.diff.gz Its passes all regression tests and my personal sets of tests. We do not introduce any new functionality. However, I expect this is an interim release. I hope to have some relatively minor modification available in the next month. These will mostly deal

Hi. I wonder what is a current position on HPN-SSH patch for OpenSSH is? I have seen a progress was made, so I was wondering if that patch is safe enough and if anyone is building it? Maybe separate package to accept connections to special port for local network (without NFS/Samba)? It is supposed to provide up to 20x more speed over ssh. Homepage is here http://www.psc.edu/index.php/hpn-ssh

http://www.psc.edu/networking/projects/hpn-ssh/ Mike Stevens and I just released a new set of high performance networking patches for OpenSSH 3.9p1, 4.0p1, and 4.1p1. These patches will provide the same set of functionality across all 3 revisions. New functionality includes 1) HPN performance even without both sides of the connection being HPN enabled. As long as the bulk data flow is in the

On the request of a coworker looking for more information about our SSH users I developed a patch that provides extended logging capability for SSHD. Its been written with an eye towards machine parsing. This patch will write the following information to the standard system log: remote ip, remote port, & remote user name protocol number and client version information Encryption method, MAC

Dear CentOS lovers, Could you consider to include a patch, http://www.psc.edu/networking/projects/hpn-ssh/ for openssh maybe as CentosPlus packages? It has great speed impact for long-distance ( high delay ) transfer. Regards, Yuji Tsuchimoto

On multiple core systems OpenSSH is limited to using a single core for all operations. On these systems this can result in a transfer being processor bound even though additional CPU resources exist. In order to open up this bottleneck we've developed a multi-threaded version of the AES-CTR cipher. Unlike CBC mode, since there is no dependency between cipher blocks in CTR mode we

Hello, I know that this has been asked before, just wanted to mention that I, too, would like to see the HPN SSH functionality incorporated in the standard OpenSSH. Would there be technical disadvantages integrating the changes? I know we are all pretty busy, but I would certainly spend time to help, e.g. with testing, documentation, etc. Cheers --pwo -- Peter W. Osel - http://pwo.de/ - pwo

Hi, I tried different encryptions like arc four, but always with the same result. BTW: googling shows some similar questions and they are stuck on set same speed +-.
