>From the kernel help: The maximum number of Unix98 PTYs that can be used at any one time. The default is 256, and should be enough for desktop systems. Server machines which support incoming telnet/rlogin/ssh connections and/or serve several X terminals may want to increase this: every incoming connection and every xterm uses up one PTY.
When not in use, each additional set of 256 PTYs occupy approximately 8 KB of kernel memory on 32-bit architectures. COnfiguring Apache for 1000 connection will not apply, since apache starts with a certain number of daemons in memory & can grow up to a certain point. It all depends upon the load. -Rob > On 11 Dec 2001 10:14:00 -0500 > "Robert Dege" <[EMAIL PROTECTED]> wrote: > > 2) ptys.
