http://devcentral.f5.com/weblogs/macvittie/archive/2011/01/31/dispelling-the-new-ssl-myth.aspx according to the SSL Performance table it says that the transactions per second is 2-3 times better using 64bit kernels opposite to 32bit kernels? is this true, or i am just misunderstanding something Thank you!
OpenSSH could be faster...then why don't they path it??
https://www.psc.edu/networking/projects/hpn-ssh/hpn-v-ssh-tput.jpg SCP and the underlying SSH2 protocol implementation in OpenSSH is network performance limited by statically defined internal flow control buffers. 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 to be defined at run time eliminates this bottleneck. We have created a patch that will remove the bottlenecks in OpenSSH and is fully interoperable with other servers and clients. In addition HPN clients will be able to download faster from non HPN servers, and HPN servers will be able to receive uploads faster from non HPN clients. However, the host receiving the data must have a properly tuned TCP/IP stack. My question is: So Why Does the original OpenSSH has limited statically defined internal flow control buffers?? It could be way faster, even 10x!! With the HPN-SCP path it could be the descendant of FTP! Why aren't there any OpenSCP packages? ('normal SCP+HPN-SCP path+no local user needed for SCP'ing+chroot by default') Any opinions? Thank you!

internet connection tester script
http://pastebin.com/raw.php?i=rykHdvBh bix.hu and www.yahoo.com are pingable test sites. 127.0.0.1 could not be pinged [firewall drops all icmp] i have a oneliner that echoes if theres internet connection or no. $ ping -W 1 -c 2 bix.hu gt;amp; /dev/null amp;amp; ping -W 1 -c 2 www.yahoo.com gt;amp; /dev/null amp;amp; echo internet connection ok || echo no internet connection internet connection ok $ ping -W 1 -c 2 127.0.0.1 gt;amp; /dev/null amp;amp; ping -W 1 -c 2 www.yahoo.com gt;amp; /dev/null amp;amp; echo internet connection ok || echo no internet connection no internet connection $ ping -W 1 -c 2 127.0.0.1 gt;amp; /dev/null amp;amp; ping -W 1 -c 2 127.0.0.1 gt;amp; /dev/null amp;amp; echo internet connection ok || echo no internet connection no internet connection $ ping -W 1 -c 2 bix.hu gt;amp; /dev/null amp;amp; ping -W 1 -c 2 127.0.0.1 gt;amp; /dev/null amp;amp; echo internet connection ok || echo no internet connection no internet connection $ ping -W 1 -c 2 bix.hu gt;amp; /dev/null amp;amp; ping -W 1 -c 2 www.yahoo.com gt;amp; /dev/null amp;amp; echo internet connection ok || echo no internet connection internet connection ok $ Ok! But: if i want the oneliner to only go along when theres internet connection: $ while $TORF; do ping -W 1 -c 1 bix.hu gt;amp; /dev/null amp;amp; ping -W 1 -c 1 www.yahoo.com gt;amp; /dev/null amp;amp; TORF=false || TORF=true; done $ while $TORF; do ping -W 1 -c 1 127.0.0.1 gt;amp; /dev/null amp;amp; ping -W 1 -c 1 www.yahoo.com gt;amp; /dev/null amp;amp; TORF=false || TORF=true; done $ while $TORF; do ping -W 1 -c 1 127.0.0.1 gt;amp; /dev/null amp;amp; ping -W 1 -c 1 127.0.0.1 gt;amp; /dev/null amp;amp; TORF=false || TORF=true; done $ while $TORF; do ping -W 1 -c 1 bix.hu gt;amp; /dev/null amp;amp; ping -W 1 -c 1 127.0.0.1 gt;amp; /dev/null amp;amp; TORF=false || TORF=true; done $ while $TORF; do ping -W 1 -c 1 bix.hu gt;amp; /dev/null amp;amp; ping -W 1 -c 1 www.yahoo.com gt;amp; /dev/null amp;amp; TORF=false || TORF=true; done $ It just doesn't work. Goal: if theres no internet connection, then the oneliner must loop until there is internet connection. if theres internet connection the oneliner ends. what am i missing?
putting /tmp to memory help
to memory means: mounting a ~2 GByte filesystem [ tmpfs?, or ramfs? ], and put the /tmp on it. [ e.g.: 4 GByte ram in the pc ]. what to write in the /etc/fstab? I would like to collect the [ answers too:P ]: Advantages: - Memory is way faster then HDD/SSD, so it could speed things up - SSD amortization is less Disadvantages: - Security? [ how to set this up to be secure? any clear howtos/links regarding it? :O ] Really thank you for any good help...
