MECH(5) File Formats and Configurations MECH(5)
NAME
mech, qop - mechanism and QOP files
SYNOPSIS
/etc/gss/mech /etc/gss/qopDESCRIPTION
The
/etc/gss/mech and
/etc/gss/qop files contain tables showing
installed security mechanisms and the Quality of Protection (
QOP)
associated with them, respectively. As security mechanisms are
installed on the system, entries are added to these two files.
Contents of these files may be accessed either manually or
programmatically. For example, manually with
cat(1) or
more(1), or
programmatically with either
rpc_gss_get_mechanisms(3NSL) or
rpc_gss_get_mech_info(3NSL).
The order of entries in the
/etc/gss/mech file is significant: the
order should be from the most preferred to the least preferred
mechanisms.
The
/etc/gss/mech file contains five fields:
mechanism name ASCII string representing the mechanism.
object identifier RPC OID for this mechanism.
shared library Shared library which implements the services provided by this
mechanism.
kernel module Kernel module which implements the services provided by this
mechanism.
library options (optional field)
Optional parameters that are interpreted by the individual
mechanism with which they are associated. Specific supported
options are described in the documentation for the individual
mechanism, if any. Not all mechanisms have support for optional
parameters.
library options must be enclosed in brackets (
[ ]) so
they may be differentiated from the optional kernel module
entries.
The
/etc/gss/qop file contains three fields:
QOP string Name, in
ASCII, of this Quality of Protection.
QOP value Numeric value by which
RPC identifies this
QOP.
mechanism name ASCII string representing the mechanism with which
this
QOP is associated.
