MECH(5) FreeBSD File Formats Manual MECH(5)

mech, qop
GSS-API Mechanism and QOP files

/etc/gss/mech /etc/gss/qop

The /etc/gss/mech file contains a list of installed GSS-API security mechanisms. Each line of the file either contains a comment if the first character is '#' or it contains five fields with the following meanings:
Name
The name of this GSS-API mechanism.
Object identifier
The OID for this mechanism.
Library
A shared library containing the implementation of this mechanism.
Kernel module
Optional kernel module containing the implementation of this mechanism (not yet supported in FreeBSD).
Library options
Optional parameters interpreted by the mechanism. Library options must be enclosed in brackets ([ ]) to differentiate them from the optional kernel module entry.
The first mechanism listed in /etc/gss/mech is the default mechanism. This mechanism will be used by gss_init_sec_context(3) if the user doesn't specify a specific mechanism.
The /etc/gss/qop file contains a list of Quality of Protection values for use with GSS-API. Each line of the file either contains a comment if the first character is '#' or it contains three fields with the following meanings:
QOP string
The name of this Quality of Protection algorithm.
QOP value
The numeric value used to select this algorithm for use with GSS-API functions such as gss_get_mic(3).
Mechanism name
The GSS-API mechanism name that corresponds to this algorithm.

This is a typical entry from /etc/gss/mech:
kerberosv5	1.2.840.113554.1.2.2	/usr/lib/libgssapi_krb5.so.8	-
This is a typical entry from /etc/gss/qop:
GSS_KRB5_CONF_C_QOP_DES		0x0100	kerberosv5

The mech manual page first appeared in FreeBSD 7.0.

This manual page was written by Doug Rabson <dfr@FreeBSD.org>.
