RADIUS & Billing MVTS Pro
by Mohamed Daif 20 Jan '12

20 Jan '12

Hello, I have installed two servers with MVTS PRO installed on both servers , supports 600 concurrent calls. and i installed one server with FreeRADIUS to manage both servers and billing "with daloRADIUS". and i have some needs must to be in the FreeRADIUS to manage the calls . all calls must be checked firstly from two tables then go to Specific Gateways like below : 1 - BlackList : to block calls to numbers from the BlackList table , 2 - WhiteList : to send calls to numbers from the WhiteList table to White Gateways 3 - Other calls not stored in both tables must be send to Checking Gateways . 4 - if calls have a good CDR must be storing in WhiteList . 5 - other calls have a bad CDR must be storing in BlackList . I want to have free choice for activate checking from both tables or one of both tables or don't check any tables for each client individually. how can i add both tables to FreeRADIUS and make configuration to check before sending calls to MVTS Servers. -- *Best Regards Mohamed Daif*

mods-available and mods-enabled for v2.1.x
by Fajar A. Nugraha 19 Jan '12

19 Jan '12

Hi Alan, I've ported mods-available and mods-enabled to v2.1.x, but with a different approach that what was implemented in master. It's currently a patch to the debian directory which will only affect debian package. Full commit: https://github.com/fajarnugraha/freeradius-server/commit/a4e2942 The idea is: - exisisting debian/ubuntu with freeradius package installed can upgrade to latest version and (if they choose to keep old radiusd.conf) have everything continue to work just as it was before (modules are loaded from modules/ directory) - new users (or those chose to replace radiusd.conf with the one in the package) will get 3.x behavior (modules loaded from mods-enabled/) - mods-availabe is just a symlink to modules - everything that's in mods-available (or to be accurate, everything listed in DEFAULT_MODULES) is symlinked to mods-enabled If you're interested in applying the change upstream (not just for debian build), the alternate commit is here: https://github.com/fajarnugraha/freeradius-server/commit/284198c -- Fajar

Patch to add /etc/default/freeradius to debian package
by Matthew Newton 14 Jan '12

14 Jan '12

Hi, Another simple patch - this one adds /etc/default/freeradius to the debian package to allow daemon options to be easily set. I sent the patch to Debian and it was included a year or so ago (closed debian bug #564716), but not yet in the main distribution. https://github.com/mcnewton/freeradius-server/commit/5d0d6d23b27949ba8c3504… Cheers!

Fix typo in rlm_dbm_parser man page
by John Dennis 14 Jan '12

14 Jan '12

rlm_dbm_parser is installed in /usr/bin but it's man page (and it's contents) call it rlm_dbm_parse (note the missing trailing r). The name of the man page and the executable it documents need to match. Attached is a git patch (can be applied with git am) to fix the naming. It should be applied to all the branches.

DHCP: ARP issue, FR2.x vs FR 3.x
by Fajar A. Nugraha 13 Jan '12

13 Jan '12

I'm trying to test a simple DHCP server implementation using FR. The setup: - server is using dummy1 interface for dhcp server test purposes, IP 172.16.101.1 - client is using virtualbox running on server, with client's eth0 bridged to server's dummy1, tested using client's "dhclient" command. - basic DHCP test using dnsmasq and FR 3 (with freeradius -X) on server works fine, so there's no issue about using dummy interface and virtualbox. Then I test FR 2.2.0 (from v2.1.x git). The dhcp listen section is different, so I adusted it accordingly. But there seems to be a problem with arp, and the reply never recached the client (also confirmed with tcpdump). Any idea how to make FR2's DHCP work, or at least behaves similar to FR3?

OCSP failure with nonce - patch for option use_nonce
by Matthew Newton 12 Jan '12

12 Jan '12

Hi, Testing OCSP today, it took a while to realise that the server didn't support nonce, but freeradius always sends it. This meant all OCSP requests were rejected as 'unauthorised'. It turns out that the MS Certificate Services responder ships with nonce support disabled, but it can be enabled, which did fix our issue. However reading around the web it sounds like there are responders out there that can't cope with nonce. So here's a patch that adds a new option to the OCSP settings, 'use_nonce', which defaults to yes. Tested here (v2.1.x branch) and it means that the certificate validation will still work if the server can't understand nonce. Obviously there's an increased chance of a replay attack with it disabled, so I added a warning to the config that recommends not turning it off unless necessary. Patch for v2.1.x branch: https://github.com/mcnewton/freeradius-server/commit/1f52a80b62d00fa2200487… and against master (untested, I confess): https://github.com/mcnewton/freeradius-server/commit/f9578ba407934d0a27a7e1… It looks sane to me, and works, but probably needs eyeballing by someone with openssl knowledge to ensure I haven't done something stupid.

3.0 (master) build error
by Fajar A. Nugraha 12 Jan '12

12 Jan '12

Hi, Not sure if this mail is better of freeradius-devel or -user. I'm posting it to -devel since 3.0 is not released yet. I'm trying to build master branch (last commit d1dfb80) on Ubuntu natty (gcc-4.5.2) with a simple ./configure && make, and the build failed with this error: CC listen.c listen.c: In function 'proxy_new_listener': listen.c:2403:21: error: 'buffer' undeclared (first use in this function) listen.c:2403:21: note: each undeclared identifier is reported only once for each function it appears in listen.c: In function 'listen_init': listen.c:2863:4: warning: passing argument 1 of 'cf_sectiontoitem' discards qualifiers from pointer target type /data/build/freeradius-server-3.0.0/src/freeradius-devel/conffile.h:101:12: note: expected 'struct CONF_SECTION *' but argument is of type 'const struct CONF_SECTION *' listen.c:2864:4: warning: passing argument 1 of 'cf_sectiontoitem' discards qualifiers from pointer target type /data/build/freeradius-server-3.0.0/src/freeradius-devel/conffile.h:101:12: note: expected 'struct CONF_SECTION *' but argument is of type 'const struct CONF_SECTION *' listen.c: At top level: listen.c:54:13: warning: 'print_packet' defined but not used make[4]: *** [listen.lo] Error 1 make[3]: *** [main] Error 2 make[2]: *** [all] Error 2 make[1]: *** [src] Error 2 make: *** [all] Error 2 Any known workaround for this? -- Fajar

Patch to use query_timeout in rlm_sql_mysql
by Brian De Wolf 12 Jan '12

12 Jan '12

Greetings, When I was setting up freeradius to use our existing multi-master MySQL setup, I noticed that freeradius would hang seemingly forever if one of the MySQL servers failed to respond (or wasn't responding during startup). The rlm_sql module has a query_timeout option but it wasn't being used in the mysql driver. The attached patch adds the appropriate lines to set mysql library options to use timeouts based on query_timeout for connecting, reads, and writes. The only confusing caveat is that the read and write timeouts apparently have retries built-in, so the timeout is effectively 3 times the query_timeout time. Also, the connect timeout would ideally be a different variable, but I didn't see an existing variable for such a purpose and felt it simplified the patch if I didn't add one. Other than this problem, freeradius has been great. Thanks! Brian

Patch to set group ownership of linelog file
by Matthew Newton 11 Jan '12

11 Jan '12

Hi, I couldn't find a way to set the group of the log file written by linelog, so I wrote code to do it. It adds a 'group' option to the linelog config. Obviously it can only change the file group if the user running freeradius is already in the new group. To use you'd probably also want to set the 'permissions' option to '0640' to allow the new group to read the logs. Patch below is for 2.1.12, and applies cleanly to v2.1.x and master HEAD. I'm working on the same for rlm_detail. Cheers, Matthew commit 3457c424255b0996bfd1549d1a76c6ecf6f240e5 Author: Matthew Newton <mcn4(a)leicester.ac.uk> Date: Tue Jan 10 12:45:42 2012 +0000 Add new 'group' option to rlm_linelog rlm_linelog saves its log files as the user/group of the running freeradius daemon.
