Understanding the IP Pool module
Hello Everyone I am hoping to use rlm_ippool and I would like to understand a bit about how it works. Firstly I want to understand the format of the database. I can see from the output of rlm_ippool_tool that there are five columns :- Key | IP Address | Active | CLI | Num It is obvious what the first two are, and I am not sure about the last three, but I guess that active means that this address is in use. Could anyone explain to me what the columns cli and num are used for? I noticed that this module is called from the post-auth and accounting sections, and in the accounting section of sites-available/default there is the following comment :- # Return an address to the IP Pool when we see a stop record. Does this mean that the ippool module sets active to 0 when it sees an accounting Stop from the same Key? Also, I noticed that this module can be used for DHCP which obviously does not have an accounting section. Does this mean that IP addresses can never be deallocated from the pool? Thanks in advance for any help. Ben - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html

Firstly I want to understand the format of the database. The best approach is to look at the documentation, followed by the code. I have had a look at the code and have been able to work out a few things. I will write my findings here, both for my own reference and for others who might ask the same questions in the future. Regarding the active flag: as I understand it so far, this is basically supposed to indicate whether a session (e.g. PPP,) is currently up and using this address. The theory being that the flag is set to 1 when the IP is dished out during RADIUS post-auth, and it is set to 0 when the accounting stop is recieved. I also figured out that cli flag is the Calling-Station-Id and this is used as an identifier in Multilink PPP sessions. It would appear that in the old days of bundling together conections with dial up modems (to get more bandwidth) it was necessary to issue the same address in mutliple authentication requests. One thing I still don't understand though is how best to use ippool for DHCP. I don't understand where and how I should call the module during a DHCP transaction. For example I can call it during DHCP-Discover, but it seems that if I call it again during DHCP-Request I might get different address even when the key is the same. I will continue to to study the code to see why this happens and if I figure it out I will report back with my findings. If anyone else knows the answers, I would be grateful hear from them. - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
Trucation of octet attribute handled by rlm_perl
Hello everyone
I am having a slight problem with rlm_perl and I would really
appreciate any advice/help.
I have a perl script which rlm_perl adds a value to the
DHCP-Classless-Static-Route attribute something like this :-
perl script snippets
...
my $route = pack('C7', split(/\,/, 16,172,16,10,0,0,2));
...
radiusd::radlog(RADLOG_DEBUG, packed data: . unpack('H*', $route));
...
$RAD_REPLY{'DHCP-Classless-Static-Route'} = $route;
...
###
..but from the debug output I see that the attribute data is truncated
at the first octet with value 00 :-
### freeradius -Xx snippets
...
Thu Feb 28 10:35:23 2013 : rlm_perl: packed data: 10ac100a02
Thu Feb 28 10:35:23 2013 : Debug: rlm_perl: Added pair
DHCP-Classless-Static-Route = ???
...
DHCP-Classless-Static-Route = 0x10ac100a
##
Am I doing somthething daft, or is this a possible bug in rlm_perl?
I am using freeradius 2.2.0.

Packet-Original-Timestamp
Hello Everyone
I have a NAS which is not sending Event-Timestamp in accounting
messages. I wondered if I could create it in unlang by subtracting
Acct-Delay-Time from Packet-Original-Timestamp. However, when I put a
reference to Packet-Original-Timestamp in the acconting setion I get
the following error :-
Reference ${Packet-Original-Timestamp} not found
Am I doing something wrong?

Many thanks for you help.
2013/3/1 Iliya Peregoudov iperegu...@cboss.ru:
All attributes in rlm_perl scripts should be text. rlm_perl convert them to
text before function call and convert them from text after function return.
So you should use
$RAD_REPLY{'DHCP-Classless-Static-Route'} = '0x'.unpack('H*', $route);

Packet-Original-Timestamp is only set by the detail file reader.
Event-Timestamp should be set in accounting if you call preprocess in
preacct*.

I tried checking out the git master code, but it just hangs when
calling rlm_perl. This is the last line I see when running in debug
mode :-

Is Packet-Original-Timestamp definitely not usable in v2.x?

Packet-Original-Timestamp as I explained before is *only* created by the
detail reader, when it reads a packet back into the server.
Event-Timestamp was not automatically created by the preprocess module in
2.2.x but is in 3.0.0.
If you provide a backtrace more debug we can probably fix the issue with
rlm_perl.
Hi Arran
Many thanks again for the info. Sorry, I misunderstood your first
email. I understand now that as I am not using the detail reader, I am
barking up the wrong tree with Packet-Original-Timestamp.
I deleted the v3 version of FreeRADIUS, but I can recreate it and take
a backtrace if it will be useful.

Don't ask leading questions like that. It's rude.
It is usable. Arran said it was usable. You were told this.
Hi Alan
I am sorry, it was not intended to be rude. I misread Arran's email,
and misunderstood what he told me.
If you want to add Event-Timestamp, when it isn't already there, do:
if (!Event-Timestamp) {
update request {
Event-Timestamp := %l
}
}
Many thanks, I will try this.

Re: Packet-Original-Timestamp
If you could provide a backtrace of the rlm_perl module at the point it gets stuck it'd be helpful. Then we can fix it before someone else runs into the same issue.

I began work on testing with Oracle but I have come across a couple of
issues. Firstly one of my SQL statements is throwing up an error, and
secondly the server is sending a unicast reply when I need a

anyone could help me fix the broadcast/unicast problem. Here is the
full degug :-
The debug log

The broadcast flag isn't set. So the client is asking for a unicast
response.

rlm_sql_oracle: execute query failed in sql_query: ORA-00900: invalid

That needs to be fixed. I don't know much about Oracle, and I don't
have an Oracle system running to test it.
(0) DHCP: Reply will be sent unicast to your-ip-address
Sending DHCP-Offer of id 64b2e216 to 10.99.0.11:68
You should be able to fix this by doing:
update reply {
DHCP-Flags = Broadcast
}
Which will force the server to send a broadcast reply.

Hi Alan
Many thanks for the quick reply.
The SQL statement START TRANSACTION looks to be hard coded into
rlm_sqlippool.c but I don't know enough about Oracle etiher to say why
it is flagged as an error.
However from looking at the code I assume that it is supposed to
signify the begining of a batch of SQL statements which after
execution will be be either committed or rolled back.
My guess would be that it is a redundant command as according this page:
http://stackoverflow.com/questions/1366851/how-do-i-find-out-if-an-oracle-database-is-set-to-autocommit
- commit/rollback, is a purely client side thing.
So if a client says to Oracle here are some statements which I will
not commit straight away I guess the server reply's with why are you
telling me?.
If I am right then, I guess we can just remove the START
TRANSACTION statement for Oracle, but unfoturnately I don't know
enough myself to be sure.
I do have access to and Oracle database though, so I am happy to do
any testing, if someone else with more Oracle knowledge can advise
what we should do.
The broadcast flag did the trick thanks. Here is the DHCP discover
section I am using :-
dhcp DHCP-Discover {
update control {
Pool-Name := test_ip_pool
}
dhcp_sqlippool
update reply {
DHCP-Subnet-Mask = 255.255.255.0
DHCP-Domain-Name-Server = 192.168.12.1
DHCP-Router-Address = 10.99.0.1
DHCP-IP-Address-Lease-Time = 300
DHCP-DHCP-Server-Identifier = 10.99.0.100
}
if (DHCP-Gateway-IP-Address == 0.0.0.0) {
update reply {
DHCP-Flags = Broadcast
}
}
}
However, it seems that none of the options are added to the reply, and
for some reason an empty packet is sent to the client :-

It's a configuration item. You can change it by editing the queries,
and adding:
allocate-begin = ...
allocate-commit = ...
allocate-rollback = ...
Thanks again for the info. I have figured it out now, and after
looking at the queries.conf for for the standard sqlippool module
added this to my queries.conf :

Wrong destination port in reply to DHCP relay
Hello Everyone I have an issue with an installation of FreeRADIUS 2.2.0 configured for DHCP, and I am seeing a problem where FreeRADIUS is replying to the wrong port on the DHCP relay. The request comes in like this :- Received DHCP-Discover of id de6dc6f2 from 10.77.1.254:68 to 10.0.0.1:67 But the the server replys like this :- Sending DHCP-Offer of id de6dc6f2 to 10.77.1.254:68 The problem is that the relay is expecting the reply on port 67, so I am getting an ICMP port unreachable message back and the DHCP offer is lost. I found a similar thread from 2008 which says that this was fixed: http://lists.freeradius.org/pipermail/freeradius-users/2008-June/029146.html However, this is quite a while ago and I guess that lots of things have changed, so I would be grateful if someone could verify the current v2.2.0 code for me to check that the fix is in there.

Re: ippool-dhcp and Oracle
Many thanks. I will give it a try.
I am still working on this but, I have some further issues which I
need to resolve.
Firstly the ippool table for the oracle ippool schema contains various
columns which are defined as NOT NULL:
CREATE TABLE radippool (
id INT PRIMARY KEY,
pool_name VARCHAR(30) NOT NULL,
framedipaddress VARCHAR(30) NOT NULL,
nasipaddress VARCHAR(30) NOT NULL,
pool_key INT NOT NULL,
CalledStationId VARCHAR(64),
CallingStationId VARCHAR(64) NOT NULL,
expiry_time timestamp(0) NOT NULL,
username VARCHAR(100)
);
The problem is that we also have insert and update staements which try
to insert empty strings e.g. (taken from the standard ippol
queries.conf):
allocate-clear = UPDATE ${ippool_table} \
SET nasipaddress = '', pool_key = 0, callingstationid = '', \
expiry_time = current_timestamp - INTERVAL '1' second(1) \
WHERE pool_key = '${pool-key}'
As I understand it, and empty string and NULL are the same thing in
Oracle so this update statement will not work as is. I suppose we need
to change the schema and this is what i have done for testing, but I
want to understand why it is like this. I don't understand how the
standard ippool queries.conf ever worked as it is trying to insert
empty strings into NOT NULL columns.
I can create a new schema and send a patch, but I just wanted to
double check that this is the right thing to do.

Updating the n'th occurance of an attribute
Hello everyone
I have a quick queston. I noticed in the man page of unlang that we can
reference attributes using the syntax:
%{Attribute-Name[index]}
This is a very useful feature :-)
However, I just wanted to check whether we can update attributes in the
same way? I mean something like this:
update reply {
Attribute-Name[index] := new_value
}

I would be grateful if anyone could help to find out why error database

I also wondered if I really need the allocate-clear statement at all, as it
does not seem to do anything useful. It clears the some fields in the table
but I as far as I can see the other sql statements will work fine even if
the fields are not cleared. So I tried the setting allocate-clear as an
empty string but I recieved the following error:
