NAMEradsecproxy.conf - Radsec proxy configuration file
DESCRIPTION
When the proxy server starts, it will first check the command line
arguments, and then read the configuration file. Normally radsecproxy
will read the configuration file /usr/local/etc/radsecproxy.conf. The
command line -c option can be used to instead read an alternate file
(see radsecproxy(1) for details).
If the configuration file can not be found, the proxy will exit with an
error message. Note that there is also an include facility so that any
configuration file may include other configuration files. The proxy
will also exit on configuration errors.
CONFIGURATION SYNTAX
When the configuration file is processed, whitespace (spaces and tabs)
are generally ignored. For each line, leading and trailing whitespace
are ignored. A line is ignored if it is empty, only consists of white‐
space, or if the first non-whitespace character is a #. The configura‐
tion is generally case insensitive, but in some cases the option values
(see below) are not.
There are two types of configuration structures than can be used. The
first and simplest are lines on the format option value. That is, an
option name, see below for a list of valid options, followed by white‐
space (at least one space or tab character), followed by a value. Note
that if the value contains whitespace, then it must be quoted using ""
or ''. Any whitespace in front of the option or after the value will be
ignored.
The other type of structure is a block. A block spans at least two
lines, and has the format:
blocktype name {
option value
option value
...
}
That is, some blocktype, see below for a list of the different block
types, and then enclosed in braces you have zero or more lines that
each have the previously described option value format. Different block
types have different rules for which options can be specified, they are
listed below. The rules regarding white space, comments and quotes are
as above. Hence you may do things like:
blocktype name {
# option value
option "value with space"
...
}
Option value characters can also be written in hex. This is done by
writing the character % followed by two hexadecimal digits. If a % is
used without two following hexadecimal digits, the % and the following
characters are used as written. If you want to write a % and not use
this decoding, you may of course write % in hex; i.e., %25.
There is one special option that can be used both as a basic option and
inside all blocks. That is the option Include where the value specifies
files to be included. The value can be a single file, or it can use
normal shell globbing to specify multiple files, e.g.:
include /usr/local/etc/radsecproxy.conf.d/*.conf
The files are sorted alphabetically. Included files are read in the
order they are specified, when reaching the end of a file, the next
file is read. When reaching the end of the last included file, the
proxy returns to read the next line following the Include option.
Included files may again include other files.
BASIC OPTIONS
The following basic options may be specified in the configuration file.
Note that blocktypes and options inside blocks are discussed later.
Note that none of these options are required, and indeed in many cases
they are not needed. Note that you should specify each at most once.
The behaviour with multiple occurences is undefined.
PidFile
The PidFile option specifies the name of a file to which the
process id (PID) will be written. This is overridden by the -i
command line option. There is no default value for the PidFile
option.
LogLevel
This option specifies the debug level. It must be set to 1, 2,
3, 4 or 5, where 1 logs only serious errors, and 5 logs every‐
thing. The default is 2 which logs errors, warnings and a few
informational messages. Note that the command line option -d
overrides this.
LogDestination
This specifies where the log messages should go. By default the
messages go to syslog with facility LOG_DAEMON. Using this
option you can specify another syslog facility, or you may spec‐
ify that logging should be to a particular file, not using sys‐
log. The value must be either a file or syslog URL. The file URL
is the standard one, specifying a local file that should be
used. For syslog, you must use the syntax: x-syslog:///FACILITY
where FACILITY must be one of LOG_DAEMON, LOG_MAIL, LOG_USER,
LOG_LOCAL0, LOG_LOCAL1, LOG_LOCAL2, LOG_LOCAL3, LOG_LOCAL4,
LOG_LOCAL5, LOG_LOCAL6 or LOG_LOCAL7. You may omit the facility
from the URL to specify logging to the default facility, but
this is not very useful since this is the default log destina‐
tion. Note that this option is ignored if -f is specified on the
command line.
FTicksReporting
The FTicksReporting option is used to enable F-Ticks logging and
can be set to None, Basic or Full. Its default value is None. If
FTicksReporting is set to anything other than None, note that
the default value for FTicksMAC is VendorKeyHashed which needs
FTicksKey to be set.
See radsecproxy.conf-example for details. Note that radsecproxy
has to be configured with F-Ticks support (--enable-fticks) for
this option to have any effect.
FTicksMAC
The FTicksMAC option can be used to control if and how Calling-
Station-Id (the users Ethernet MAC address) is being logged. It
can be set to one of Static, Original, VendorHashed, VendorKey‐
Hashed, FullyHashed or FullyKeyHashed.
The default value for FTicksMAC is VendorKeyHashed. This means
that FTicksKey has to be set.
Before chosing any of Original, FullyHashed or VendorHashed,
consider the implications for user privacy when MAC addresses
are collected. How will the logs be stored, transferred and
accessed?
See radsecproxy.conf-example for details. Note that radsecproxy
has to be configured with F-Ticks support (--enable-fticks) for
this option to have any effect.
FTicksKey
The FTicksKey option is used to specify the key to use when pro‐
ducing HMAC's as an effect of specifying VendorKeyHashed or Ful‐
lyKeyHashed for the FTicksMAC option.
Note that radsecproxy has to be configured with F-Ticks support
(--enable-fticks) for this option to have any effect.
FTicksSyslogFacility
The FTicksSyslogFacility option is used to specify a dedicated
syslog facility for F-Ticks messages. This allows for easier
filtering of F-Ticks messages. If no FTicksSyslogFacility option
is given, F-Ticks messages are written to what the LogDestina‐
tion option specifies.
F-Ticks messages are always logged using the log level
LOG_DEBUG. Note that specifying a file in FTicksSyslogFacility
(using the file:/// prefix) is not supported.
ListenUDP
Normally the proxy will listen to the standard RADIUS UDP port
1812 if configured to handle UDP clients. On most systems it
will do this for all of the system's IP addresses (both IPv4 and
IPv6). On some systems however, it may respond to only IPv4 or
only IPv6. To specify an alternate port you may use a value on
the form *:port where port is any valid port number. If you also
want to specify a specific address you can do e.g.
192.168.1.1:1812 or [2001:db8::1]:1812. The port may be omitted
if you want the default one (like in these examples). These
examples are equivalent to 192.168.1.1 and 2001:db8::1. Note
that you must use brackets around the IPv6 address. This option
may be specified multiple times to listen to multiple addresses
and/or ports.
ListenTCP
This option is similar to the ListenUDP option, except that it
is used for receiving connections from TCP clients. The default
port number is 1812.
ListenTLS
This is similar to the ListenUDP option, except that it is used
for receiving connections from TLS clients. The default port
number is 2083. Note that this option was previously called Lis‐
tenTCP.
ListenDTLS
This is similar to the ListenUDP option, except that it is used
for receiving connections from DTLS clients. The default port
number is 2083.
SourceUDP
This can be used to specify source address and/or source port
that the proxy will use for sending UDP client messages (e.g.
Access Request).
SourceTCP
This can be used to specify source address and/or source port
that the proxy will use for TCP connections.
SourceTLS
This can be used to specify source address and/or source port
that the proxy will use for TLS connections.
SourceDTLS
This can be used to specify source address and/or source port
that the proxy will use for DTLS connections.
TTLAttribute
This can be used to change the default TTL attribute. Only
change this if you know what you are doing. The syntax is either
a numerical value denoting the TTL attribute, or two numerical
values separated by column specifying a vendor attribute, i.e.
vendorid:attribute.
AddTTL If a TTL attribute is present, the proxy will decrement the
value and discard the message if zero. Normally the proxy does
nothing if no TTL attribute is present. If you use the AddTTL
option with a value 1-255, the proxy will when forwarding a mes‐
sage with no TTL attribute, add one with the specified value.
Note that this option can also be specified for a client/server.
It will then override this setting when forwarding a message to
that client/server.
LoopPrevention
This can be set to on or off with off being the default. When
this is enabled, a request will never be sent to a server named
the same as the client it was received from. I.e., the names of
the client block and the server block are compared. Note that
this only gives limited protection against loops. It can be used
as a basic option and inside server blocks where it overrides
the basic setting.
IPv4Only and IPv6Only
These can be set to on or off with off being the default. At
most one of IPv4Only and IPv6Only can be enabled. Enabling
IPv4Only or IPv6Only makes radsecproxy resolve DNS names to the
corresponding address family only, and not the other. This is
done for both clients and servers. Note that this can be over‐
ridden in client and server blocks, see below.
Include
This is not a normal configuration option; it can be specified
multiple times. It can both be used as a basic option and inside
blocks. For the full description, see the configuration syntax
section above.
BLOCKS
There are five types of blocks, they are client, server, realm, tls and
rewrite. At least one instance of each of client and realm is required.
This is necessary for the proxy to do anything useful, and it will exit
if not. The tls block is required if at least one TLS/DTLS client or
server is configured. Note that there can be multiple blocks for each
type. For each type, the block names should be unique. The behaviour
with multiple occurences of the same name for the same block type is
undefined. Also note that some block option values may reference a
block by name, in which case the block name must be previously defined.
Hence the order of the blocks may be significant.
CLIENT BLOCK
The client block is used to configure a client. That is, tell the proxy
about a client, and what parameters should be used for that client. The
name of the client block must (with one exception, see below) be either
the IP address (IPv4 or IPv6) of the client, an IP prefix (IPv4 or
IPv6) on the form IpAddress/PrefixLength, or a domain name (FQDN). The
way an FQDN is resolved into an IP address may be influenced by the use
of the IPv4Only and IPv6Only options. Note that literal IPv6 addresses
must be enclosed in brackets.
If a domain name is specified, then this will be resolved immediately
to all the addresses associated with the name, and the proxy will not
care about any possible DNS changes that might occur later. Hence there
is no dependency on DNS after startup.
When some client later sends a request to the proxy, the proxy will
look at the IP address the request comes from, and then go through all
the addresses of each of the configured clients (in the order they are
defined), to determine which (if any) of the clients this is.
In the case of TLS/DTLS, the name of the client must match the FQDN or
IP address in the client certificate. Note that this is not required
when the client name is an IP prefix.
Alternatively one may use the host option inside a client block. In
that case, the value of the host option is used as above, while the
name of the block is only used as a descriptive name for the adminis‐
trator. The host option may be used multiple times, and can be a mix of
addresses, FQDNs and prefixes.
The allowed options in a client block are host, IPv4Only, IPv6Only,
type, secret, tls, certificateNameCheck, matchCertificateAttribute,
duplicateInterval, AddTTL, fticksVISCOUNTRY, fticksVISINST, rewrite,
rewriteIn, rewriteOut, and rewriteAttribute. We already discussed the
host option. To specify how radsecproxy should resolve a host given as
a DNS name, the IPv4Only or the IPv6Only can be set to on. At most one
of these options can be enabled. Enabling IPv4Only or IPv6Only here
overrides any basic settings set at the top level. The value of type
must be one of udp, tcp, tls or dtls. The value of secret is the shared
RADIUS key used with this client. If the secret contains whitespace,
the value must be quoted. This option is optional for TLS/DTLS and if
omitted will default to "radsec". (Note that using a secret other than
"radsec" for TLS is a violation of the standard (RFC 6614) and that the
proposed standard for DTLS stipulates that the secret must be
"radius/dtls".)
For a TLS/DTLS client you may also specify the tls option. The option
value must be the name of a previously defined TLS block. If this
option is not specified, the TLS block with the name defaultClient will
be used if defined. If not defined, it will try to use the TLS block
named default. If the specified TLS block name does not exist, or the
option is not specified and none of the defaults exist, the proxy will
exit with an error. NOTE: All versions of radsecproxy up to and
including 1.6 erroneously verify client certificate chains using the CA
in the very first matching client block regardless of which block is
used for the final decision. This was changed in version 1.6.1 so that
a client block with a different tls option than the first matching
client block is no longer considered for verification of clients.
For a TLS/DTLS client, the option certificateNameCheck can be set to
off, to disable the default behaviour of matching CN or SubjectAltName
against the specified hostname or IP address.
Additional validation of certificate attributes can be done by use of
the matchCertificateAttribute option. Currently one can only do some
matching of CN and SubjectAltName. For regexp matching on CN, one can
use the value CN:/regexp/. For SubjectAltName one can only do regexp
matching of the URI, this is specified as SubjectAltName:URI:/regexp/.
Note that currently this option can only be specified once in a client
block.
The duplicateInterval option can be used to specify for how many sec‐
onds duplicate checking should be done. If a proxy receives a new
request within a few seconds of a previous one, it may be treated the
same if from the same client, with the same authenticator etc. The
proxy will then ignore the new request (if it is still processing the
previous one), or returned a copy of the previous reply.
The AddTTL option is similar to the AddTTL option used in the basic
config. See that for details. Any value configured here overrides the
basic one when sending messages to this client.
The fticksVISCOUNTRY option configures clients eligible to F-Ticks log‐
ging as defined by the FTicksReporting basic option.
The fticksVISINST option overwrites the default VISINST value taken
from the client block name.
The rewrite option is deprecated. Use rewriteIn instead.
The rewriteIn option can be used to refer to a rewrite block that spec‐
ifies certain rewrite operations that should be performed on incoming
messages from the client. The rewriting is done before other process‐
ing. For details, see the rewrite block text below. Similarly to tls
discussed above, if this option is not used, there is a fallback to
using the rewrite block named defaultClient if it exists; and if not, a
fallback to a block named default.
The rewriteOut option is used in the same way as rewriteIn, except that
it specifies rewrite operations that should be performed on outgoing
messages to the client. The rewriting is done after other processing.
Also, there is no rewrite fallback if this option is not used.
The rewriteAttribute option currently makes it possible to specify that
the User-Name attribute in a client request shall be rewritten in the
request sent by the proxy. The User-Name attribute is written back to
the original value if a matching response is later sent back to the
client. The value must be on the form User-Name:/regexpmatch/replace‐
ment/. Example usage:
rewriteAttribute User-Name:/^(.*)@local$/\1@example.com/
SERVER BLOCK
The server block is used to configure a server. That is, tell the proxy
about a server, and what parameters should be used when communicating
with that server. The name of the server block must (with one excep‐
tion, see below) be either the IP address (IPv4 or IPv6) of the server,
or a domain name (FQDN). If a domain name is specified, then this will
be resolved immediately to all the addresses associated with the name,
and the proxy will not care about any possible DNS changes that might
occur later. Hence there is no dependency on DNS after startup. If the
domain name resolves to multiple addresses, then for UDP/DTLS the first
address is used. For TCP/TLS, the proxy will loop through the addresses
until it can connect to one of them. The way an FQDN is resolved into
an IP address may be influenced by the use of the IPv4Only and IPv6Only
options. In the case of TLS/DTLS, the name of the server must match the
FQDN or IP address in the server certificate.
Alternatively one may use the host option inside a server block. In
that case, the value of the host option is used as above, while the
name of the block is only used as a descriptive name for the adminis‐
trator. Note that multiple host options may be used. This will then be
treated as multiple names/addresses for the same server. When initiat‐
ing a TCP/TLS connection, all addresses of all names may be attempted,
but there is no failover between the different host values. For
failover one must use separate server blocks.
Note that the name of the block, or values of host options may include
a port number (separated with a column). This port number will then
override the default port or a port option in the server block. Also
note that literal IPv6 addresses must be enclosed in brackets.
The allowed options in a server block are host, port, IPv4Only,
IPv6Only, type, secret, tls, certificateNameCheck, matchCertificateAt‐
tribute, AddTTL, rewrite, rewriteIn, rewriteOut, statusServer,
retryCount, dynamicLookupCommand and retryInterval and LoopPrevention.
We already discussed the host option. To specify how radsecproxy should
resolve a host given as a DNS name, the IPv4Only or the IPv6Only can be
set to on. At most one of these options can be enabled. Enabling
IPv4Only or IPv6Only here overrides any basic settings set at the top
level. The port option allows you to specify which port number the
server uses. The usage of type, secret, tls, certificateNameCheck,
matchCertificateAttribute, AddTTL, rewrite, rewriteIn and rewriteOut
are just as specified for the client block above, except that default‐
Server (and not defaultClient) is the fallback for the tls, rewrite and
rewriteIn options.
statusServer can be specified to enable the use of status-server mes‐
sages for this server. The value must be either on or off. The default
when not specified, is off. If statusserver is enabled, the proxy will
during idle periods send regular status-server messages to the server
to verify that it is alive. This should only be enabled if the server
supports it.
The options retryCount and retryInterval can be used to specify how
many times the proxy should retry sending a request and how long it
should wait between each retry. The defaults are 2 retries and an
interval of 5s.
The option dynamicLookupCommand can be used to specify a command that
should be executed to dynamically configure a server. The executable
file should be given with full path and will be invoked with the name
of the realm as its first and only argument. It should either print a
valid server option on stdout and exit with a code of 0 or print noth‐
ing and exit with a non-zero exit code. An example of a shell script
resolving the DNS NAPTR records for the realm and then the SRV records
for each NAPTR matching 'x-eduroam:radius.tls' is provided in
tools/naptr-eduroam.sh. This option was added in radsecproxy-1.3 but
tends to crash radsecproxy versions earlier than 1.6.
Using the LoopPrevention option here overrides any basic setting of
this option. See section BASIC OPTIONS for details on this option.
REALM BLOCK
When the proxy receives an Access-Request it needs to figure out to
which server it should be forwarded. This is done by looking at the
Username attribute in the request, and matching that against the names
of the defined realm blocks. The proxy will match against the blocks in
the order they are specified, using the first match if any. If no realm
matches, the proxy will simply ignore the request. Each realm block
specifies what the server should do when a match is found. A realm
block may contain none, one or multiple server options, and similarly
accountingServer options. There are also replyMessage and accountingRe‐
sponse options. We will discuss these later.
REALM BLOCK NAMES AND MATCHING
In the general case the proxy will look for a @ in the username
attribute, and try to do an exact case insensitive match between what
comes after the @ and the name of the realm block. So if you get a
request with the attribute value anonymous@example.com, the proxy will
go through the realm names in the order they are specified, looking for
a realm block named example.com.
There are two exceptions to this, one is the realm name * which means
match everything. Hence if you have a realm block named *, then it will
always match. This should then be the last realm block defined, since
any blocks after this would never be checked. This is useful for having
a default.
The other exception is regular expression matching. If the realm name
starts with a /, the name is treated as an regular expression. A case
insensitive regexp match will then be done using this regexp on the
value of the entire Username attribute. Optionally you may also have a
trailing / after the regexp. So as an example, if you want to use reg‐
exp matching the domain example.com you could have a realm block named
/@example\\.com$. Optinally this can also be written /@example\\.com$/.
If you want to match all domains under the .com top domain, you could
do /@.*\\.com$. Note that since the matching is done on the entire
attribute value, you can also use rules like /^[a-k].*@example\\.com$/
to get some of the users in this domain to use one server, while other
users could be matched by another realm block and use another server.
REALM BLOCK OPTIONS
A realm block may contain none, one or multiple server options. If
defined, the values of the server options must be the names of previ‐
ously defined server blocks. Normally requests will be forwarded to the
first server option defined. If there are multiple server options, the
proxy will do fail-over and use the second server if the first is down.
If the two first are down, it will try the third etc. If say the first
server comes back up, it will go back to using that one. Currently
detection of servers being up or down is based on the use of Sta‐
tusServer (if enabled), and that TCP/TLS/DTLS connections are up.
A realm block may also contain none, one or multiple accountingServer
options. This is used exactly like the server option, except that it is
used for specifying where to send matching accounting requests. The
values must be the names of previously defined server blocks. When mul‐
tiple accounting servers are defined, there is a failover mechanism
similar to the one for the server option.
If there is no server option, the proxy will if replyMessage is speci‐
fied, reply back to the client with an Access Reject message. The mes‐
sage contains a replyMessage attribute with the value as specified by
the replyMessage option. Note that this is different from having no
match since then the request is simply ignored. You may wonder why this
is useful. One example is if you handle say all domains under say .bv.
Then you may have several realm blocks matching the domains that
exists, while for other domains under .bv you want to send a reject. At
the same time you might want to send all other requests to some default
server. After the realms for the subdomains, you would then have two
realm definitions. One with the name /@.*\\.bv$ with no servers, fol‐
lowed by one with the name * with the default server defined. This may
also be useful for blocking particular usernames.
If there is no accountingServer option, the proxy will normally do
nothing, ignoring accounting requests. There is however an option
called accountingResponse. If this is set to on, the proxy will log
some of the accounting information and send an Accounting-Response
back. This is useful if you do not care much about accounting, but want
to stop clients from retransmitting accounting requests. By default
this option is set to off.
TLS BLOCK
The TLS block specifies TLS configuration options and you need at least
one of these if you have clients or servers using TLS/DTLS. As dis‐
cussed in the client and server block descriptions, a client or server
block may reference a particular TLS block by name. There are also how‐
ever the special TLS block names default, defaultClient and default‐
Server which are used as defaults if the client or server block does
not reference a TLS block. Also note that a TLS block must be defined
before the client or server block that would use it. If you want the
same TLS configuration for all TLS/DTLS clients and servers, you need
just a single tls block named default, and the client and servers need
not refer to it. If you want all TLS/DTLS clients to use one config,
and all TLS/DTLS servers to use another, then you would be fine only
defining two TLS blocks named defaultClient and defaultServer. If you
want different clients (or different servers) to have different TLS
parameters, then you may need to create other TLS blocks with other
names, and reference those from the client or server definitions. Note
that you could also have say a client block refer to a default, even
defaultServer if you really want to.
The available TLS block options are CACertificateFile, CACertifi‐
catePath, certificateFile, certificateKeyFile, certificateKeyPassword,
cacheExpiry, CRLCheck and policyOID. When doing RADIUS over TLS/DTLS,
both the client and the server present certificates, and they are both
verified by the peer. Hence you must always specify certificateFile and
certificateKeyFile options, as well as certificateKeyPassword if a
password is needed to decrypt the private key. Note that CACertificate‐
File may be a certificate chain. In order to verify certificates, or
send a chain of certificates to a peer, you also always need to specify
CACertificateFile or CACertificatePath. Note that you may specify both,
in which case the certificates in CACertificateFile are checked first.
By default CRLs are not checked. This can be changed by setting
CRLCheck to on. One can require peer certificates to adhere to certain
policies by specifying one or multiple policyOIDs using one or multiple
policyOID options.
CA certificates and CRLs are normally cached permanently. That is, once
a CA or CRL has been read, the proxy will never attempt to re-read it.
CRLs may change relatively often and the proxy should ideally always
use the latest CRLs. Rather than restarting the proxy, there is an
option cacheExpiry that specifies how many seconds the CA and CRL
information should be cached. Reasonable values might be say 3600 (1
hour) or 86400 (24 hours), depending on how frequently CRLs are updated
and how critical it is to be up to date. This option may be set to zero
to disable caching.
REWRITE BLOCK
The rewrite block specifies rules that may rewrite RADIUS messages. It
can be used to add, remove and modify specific attributes from messages
received from and sent to clients and servers. As discussed in the
client and server block descriptions, a client or server block may ref‐
erence a particular rewrite block by name. There are however also the
special rewrite block names default, defaultClient and defaultServer
which are used as defaults if the client or server block does not ref‐
erence a block. Also note that a rewrite block must be defined before
the client or server block that would use it. If you want the same re‐
write rules for input from all clients and servers, you need just a
single rewrite block named default, and the client and servers need not
refer to it. If you want all clients to use one config, and all servers
to use another, then you would be fine only defining two rewrite blocks
named defaultClient and defaultServer. Note that these defaults are
only used for rewrite on input. No rewriting is done on output unless
explicitly specified using the rewriteOut option.
The available rewrite block options are addAttribute, addVendorAt‐
tribute, removeAttribute, removeVendorAttribute and modifyAttribute.
They can all be specified none, one or multiple times.
addAttribute is used to add attributes to a message. The option value
must be on the form attribute:value where attribute is a numerical
value specifying the attribute. Simliarly, the addVendorAttribute is
used to specify a vendor attribute to be added. The option value must
be on the form vendor:subattribute:value, where vendor and subattribute
are numerical values.
The removeAttribute option is used to specify an attribute that should
be removed from received messages. The option value must be a numerical
value specifying which attribute is to be removed. Similarly,
removeVendorAttribute is used to specify a vendor attribute that is to
be removed. The value can be a numerical value for removing all
attributes from a given vendor, or on the form vendor:subattribute,
where vendor and subattribute are numerical values, for removing a spe‐
cific subattribute for a specific vendor.
modifyAttribute is used to specify modification of attributes. The
value must be on the form attribute:/regexpmatch/replacement/ where
attribute is a numerical attribute type, regexpmatch is regexp matching
rule and replacement specifies how to replace the matching regexp.
Example usage:
modifyAttribute 1:/^(.*)@local$/\1@example.com/
