https is faster on amd64?
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! ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
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!

if the file changes send email about diff
I have 2 script. Script A, Script B. Script A is regulary watching the dhcpacks [dhcp release is configured to 2mins] in the logs, for the past 2 minutes. it writes the MAC addresses to a file [/dev/shm/dhcpacks-in-last-2min.txt] every 2 minutes. Ok, this is working, active clients are in this file. Super! Script B: http://pastebin.com/raw.php?i=wvhwhPWu I'm trying to create a script, that watches the changes in /dev/shm/dhcpacks-in-last-2min.txt file [in every 1 sec]. Ok. But: my watcher script [the pastebined] is not working fine...sometime it works, sometime it send that someone XY logged out, but it's not true! nothing happened, and the problem is not in the Script A. Can someone help me point out, what am i missing? How can i watch a file [in every sec], that contains only MAC addresses, and if someone doesn't get dhcpack in 2 minutes, the file /dev/shm/dhcpacks-in-last-2min.txt changes, and that clients MAC address will be gone from it, and i need to know, who was it [pastebined my script..but somethings wrong with it]. Thank you for any help..i've been pathing my script for days now.. :\ ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
putting /tmp to memory
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... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
