similar to: Support for merging LPK and hpn-ssh into mainline openssh?

Hello I've created patch to the openssh which allows to use an agent for obtaining the public keys. It may be the first step towards the implementation of something similar lpk. The solution is independent on the agent, so it may be used with ldap based agent or with any other technology. May be that patch acceptable as the first aproach to the lpk replacement? It is placet in mindrot's

Hello everybody, I'd like to have LPK (or something like that - getting public keys from LDAP) integrated into mainline OpenSSH. *** First of all, a summary. The project page at http://code.google.com/p/openssh-lpk/ mentions that a few distributions include LPK per default; but reading the various threads at Support for merging LPK and hpn-ssh into mainline openssh?

Hi all, At my organisation we have an LDAP infrastructure built on OpenLDAP, between Unix boxes running OpenSSH at multiple sites. It works well but the SSH key management is something of an inconvenience, especially as we would like to implement SSO with ssh-agent and passphrased keys. There is an OpenSSH patch called LPK which can allow the authorized_keys to be stored in LDAP, and that

Hello, I know this has come up before; but is the HPN patch (or elements thereof) currently being considered for integration in to the OpenSSH code base? Are there pending issues (buffer management, none cipher, etc) which still need to be addressed? We have been using HPN-SSH for over a year now, and like others, have observed significant performance improvement over standard OpenSSH. I can

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

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

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

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

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

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

If anyone is using the HPN patch on a high performance link I was wondering if you could take a moment to answer a quick question Are you seeing vastly different performance between scp throughput and sftp throughput? On my test network (pittsburgh to chicago) I'm getting 26MB/s with scp (arcfour) and only 6.4MB/s with sftp (arcfour). We just started looking into this but it woudl be nice

I have successfully created a packaged version of openssh that has the LPK patch. LPK allows you to store your public keys in LDAP. However when I go to install the package I created it complains about dependencies: [root at VIRTCENT13:/home/bluethundr/rpm]#rpm -Uvh openssh-5.6p1-1.i386.rpm error: Failed dependencies: openssh = 5.5p1-1.el5 is needed by (installed)

[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

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

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

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

This is a preliminary release and as such should be used at your own risk. In my testing the application builds under OS X and Linux, passes the regression tests, and file transfer tests on our test connections exhibited a 1600% increase in performance (1.4MB/s versus 20.9MB/s 46ms RTT). This patch (hpn12v10) is available from
