---help---
|

|
|
A pseudo terminal (PTY) is a software device consisting of two
|
||
|
|
halves: a master and a slave. The slave device behaves identical to
|
||
|
|
a physical terminal; the master device is used by a process to
|
||
|
|
read data from and write data to the slave, thereby emulating a
|
||
|
|
terminal. Typical programs for the master side are telnet servers
|
||
|
|
and xterms.
|
||
|
|
|
||
|
|
Linux has traditionally used the BSD-like names /dev/ptyxx for
|
||
|
|
masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
|
||
|
|
has a number of problems. The GNU C library glibc 2.1 and later,
|
||
|
|
however, supports the Unix98 naming standard: in order to acquire a
|
||
|
|
pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
|
||
|
|
terminal is then made available to the process and the pseudo
|
||
|
|
terminal slave can be accessed as /dev/pts/<number>. What was
|
||
|
|
traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
|
||
|
|
|
||
|
|
The entries in /dev/pts/ are created on the fly by a virtual
|
||
|
|
file system; therefore, if you say Y here you should say Y to
|
||
|
|
"/dev/pts file system for Unix98 PTYs" as well.
|
||
|
|
|
||
|
|
If you want to say Y here, you need to have the C library glibc 2.1
|
||
|
|
or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
|
||
|
|
Read the instructions in <file:Documentation/Changes> pertaining to
|
||
|
|
pseudo terminals. It's safe to say N.

|
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.
