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

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

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

[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

hello, everybody. in ror, we can add a after_filter to a controller. def aes_encrypt response.body = AesHelper.aes_encrypt(response.body) end after_filter :aes_encrypt and all action''s repsonse int the controller can be encrypt. and my question is , how to decrypt data use before_filter, or anything else. ex: i want to post json data to /usr/register, the json data is

These buffers often end up acting as a bottleneck for network throughput of SCP, especially on long and high bandwith network links. Modifying the ssh code to allow the buffers

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

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

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

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

I'm looking at replacing some algorithms with different implementations, and I'm having some problems with the AES CTR mode algorithms. I can see where encryption is done, but I can't figure out where decryption occurs. I'm looking at cipher-ctr.c ---- Scott Neugroschl XYPRO Technology Corporation scott_n at xypro.com 805-583-2874

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

Hi, I''m looking at ways to encrypt email addresses rather than storing them directly in the database. There are several ways that it could be done. I could make an Encrypter class and use before_update, etc. Or I could set up an updatable VIEW in mySql. (I guess triggers might be another possibility.) However, what I would really LIKE to do is use the handy AES_ENCRYPT and

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).

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

Hi, Is cipher "3des-ctr" supported by openssh? It is not mentioned in the list of supported ciphers in the man page of ssh_config: Thanks, Sunil Ciphers Specifies the ciphers allowed for protocol version 2 in order of preference. Multiple ciphers must be comma-separated. The supported ciphers are ''3des-cbc'', ''aes128-cbc'',

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
