The Linux version of the 9p server is now maintained under the npfs project
|
||||
on sourceforge (http://sourceforge.net/projects/npfs).
|
||||
Our current recommendation is to use Inferno (http://www.vitanuova.com/inferno)
|
||||
as the 9p server. You can start a 9p server under Inferno by issuing the
|
||||
following command:
|
||||
; styxlisten -A tcp!*!564 export '#U*'
|
||||
|
||||
The -A specifies an unauthenticated export. The 564 is the port # (you may
|
||||
have to choose a higher port number if running as a normal user). The '#U*'
|
||||
specifies exporting the root of the Linux name space. You may specify a
|
||||
subset of the namespace by extending the path: '#U*'/tmp would just export
|
||||
/tmp. For more information, see the Inferno manual pages covering styxlisten
|

and export.

The Magic SysRQ system works by registering key operations against a key op

a number of operations registered into it at compile time, but is mutable,

functions __sysrq_swap_key_ops and __sysrq_swap_key_ops_nolock are defined

in the header itself, and the REGISTER and UNREGISTER macros are built from

these. More complex (and dangerous!) manipulations of the table are possible

using these functions, but you must be careful to always lock the table before

you read or write from it, and to unlock it again when you are done. (And of

course, to never ever leave an invalid pointer in the table). Null pointers in

the table are always safe :)
