How fast various ssh ciphers are

Periodically it surprises people to learn this, but ssh is notnecessarily very fast (in the bandwidth sense). It's plenty fast fornormal interactive use, but this speed issue can matter if you aremaking large transfers with scp , rsync , or the like; depending onyour environment, ssh can go significantly slower than wire speed.

Ssh is slow because it has to encrypt and decrypt everything that goesover the wire, and this is a CPU-bound operation. How much time thistakes depends on

數據具象化 ( Data Visualization)早非甚麼新事物,但應用得好的還是少之又少。

這條短片,目的是想勸喻加拿大人盡量多多幫襯本地種植的農產品,但齋講大堆數據,可能會像高官在立法局講話一樣,悶得人發慌之餘更難聽入耳,能否說服

How we do custom NFS mount authorization on Solaris 10

Suppose that you want to use some custom method of authenticating andauthorizing NFS mounts, and that your fileservers are Solaris 10 systems(although the same general approach could probably work elsewhere).Further suppose that you don't have the source to mountd , or at leastdon't want to modify it for various sensible reasons. Fortunately,there is an evil hack that you can commit that will let you do whateverauthorization checks that you need.

The most obvious application is text-mode web browserslike links
