MECH(4)MECH(4)NAME
mech, qop - mechanism and QOP files
SYNOPSIS
/etc/gss/mech
/etc/gss/qop
DESCRIPTION
The /etc/gss/mech and /etc/gss/qop files contain tables showing
installed security mechanisms and the Quality of Protection (QOP) asso‐
ciated 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 mecha‐
nisms.
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 mech‐
anism.
kernel module
Kernel module which implements the services provided by this mecha‐
nism.
library options (optional field)
Optional parameters that are interpreted by the individual mecha‐
nism 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.
