similar to: [Bug 2676] New: error while starting sshd daemon

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 All, I have a query.. How to build the sshd_config file with all the possible parameters set to their default values.? For eg: When I compile any version of Openssh and run make install, the sshd_config file that gets copied to the directory specified by "--sysconfigdir=" flag does not contain the parameter "XAuthLocation" at all Whereas the sshd_config.5 man file

Hi I am just porting ssh-5.2 to my HPUX system. but while I'm doing it, I accidently found a different handling of the sshd for the SIGHUP signal when it is started with a "./sshd_config" and "/sshd_config". The problem is as following: root at sshpa6# uname -a HP-UX sshpa6 B.11.31 U 9000/800 2404418693 unlimited-user license root at sshpa6#

The sshd_config tweaks were executed even if the old file was still in place. Fix that. Also disable sshd user creation. It's not used on Cygwin. --- contrib/cygwin/ssh-host-config | 16 +++++++++++++--- 1 file changed, 13 insertions(+), 3 deletions(-) diff --git a/contrib/cygwin/ssh-host-config b/contrib/cygwin/ssh-host-config index 52916d14ba94..cc36ea102f42 100644 ---

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.

Hi, experimenting with openssh_cvs on my SCO Unix 3.2v4.2 machine, I had sshd core dumping on me. Tracking this, I found that if a host key is specified in the sshd_config that does not exist (I used "./sshd -d -d -d -f sshd_config" with the shipped sshd_config file, to work around incompatibilities with the installed sshd.com's sshd_config, and I do not have ssh2 host keys on

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

Hello list, right now SSH Tunnel / scp is reaches just around 76Mb/s on my E5 Xeon using AES-NI but openssl reaches around 600-700Mb/s using 128aes-cbc cipher. As far as i understand http://www.psc.edu/index.php/hpn-ssh this is due to very small buffers in ssh / scp. Is there any work on this? Like autotuning the buffer size? Are there plans to integrate the hpn patches? Greets, Stefan

I am porting over the portable version of openssh to our uCLinux implementation. Everything has worked with minimal effort and I appreciate all the work. But, I am having a problem whereby the sshd executable is crashing and I really could use some help on where to look at this in more details. Here is how I start up the sshd for testing. /usr/sbin/sshd -D -ddd -f /etc/ssh/sshd_config -p 65

Assuming in a secure and trusted env, we want to get the maximum transfer speed without the overhead from ssh. Thanks. Fred -------------- next part -------------- An HTML attachment was scrubbed...

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
