Njord SSH update

The OpenSSH client and server is updated on njord.hpc.ntnu.no. The server is updated to AIX OpenSSH v.5.2, while the client is updated to the latest HPN-SSH OpenSSH_5.5p1-hpn13v9. Both the server and the client is linked with the latest FIPS-compliant AIX OpenSSL v.0.9.8k.

 

It is possible to speed up file transfers with scp/sftp by transferring data unencrypted with the None cipher. Use the command line

 $ scp -ononeswitch=yes «from» «to»

on njord. It is important to log into njord and then read or write files to another HPN enabled system, because a HPN enabled server (sshd) is not provided with AIX. The HPN-SSH multithreaded AES cipher is not supported because it hangs with batch transfer, and because this part of HPN-SSH is not maintained. See also the ssh(1) and ssh_config(5) online manual pages.
