Hi everyone, I am testing eap2 in freeradius. I run "radiusd -X", I got following error message " radiusd: symbol lookup error: /usr/lib/rlm_eap2-2.1.0.so: undefined symbol: eap_server_register_methods " Anyone, have any idea what might be wrong with the configuration? Thank in advance, Thierry

help:when freeradius is used on 32-bit redhat linux
by yiyongyun 30 Oct '08

30 Oct '08

Dear everyone: I want to fix freeradius on 32-bit redhat linux, but I do not know the memory(8g）on 32-bit redhat linux is enough for freeradius; If not enough, then I'll fix it on 64-bit redhat linux, but this time the source of freeradius is needed to modify?

Regular expressions support in FreeRadius.
by Dmitry V. Krivenok 30 Oct '08

30 Oct '08

Hello! As doc says I must not activate regular expressions in radiusd.conf if server wasn't compiled with regexp support. How can I build freeradius with regular expressions support? ./configure --help doesn't show any regexp-related options (like --with-pcre). The following command doesn't show options radiusd was compiled with: krivenok@develop2 10:43:08 /usr/local/fr_211/sbin $ sudo ./radiusd -v radiusd: FreeRADIUS Version 2.1.1, for host i686-pc-linux-gnu, built on Oct 28 2008 at 13:10:11 Copyright (C) 1999-2008 The FreeRADIUS server project and contributors. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. You may redistribute copies of FreeRADIUS under the terms of the GNU General Public License. For more information about these matters, see the file named COPYRIGHT. krivenok@develop2 10:43:25 /usr/local/fr_211/sbin $ So, how can I check whether radiusd supports regexps? Thank you beforehand!

Segmentation fault after migrating from 2.0.5 to 2.1.1
by Dmitry V. Krivenok 29 Oct '08

29 Oct '08

Hello! I'm developing my own rlm. I copied the code below from rlm_example.c: /* * Look for the 'state' attribute. */ state = pairfind(request->packet->vps, PW_STATE); if (state != NULL) { RDEBUG("Found reply to access challenge"); return RLM_MODULE_OK; } After compiling my module under fr-2.1.1 I got segmentation fault. gdb determined that error occurs in pairfind: Program received signal SIGSEGV, Segmentation fault. [Switching to Thread 0xb7ba4ac0 (LWP 9773)] 0xb7b360fa in osb_authorize (inst=0x8179e30, request=0x819c670) at rlm_osb.c:73 73 if(pairfind(request->packet->vps, PW_STATE)) I found that request->packet is NULL. Is it correct request? How should I handle requests with packet field == NULL? Thank you beforehand! P.S. All worked fine with fr-2.0.5.

Help with attr_rewrite

Hello, I have clients that authenticate with username/pw void/void and a Calling-Station-Id. I would like to replace the User-Name attribute with Calling-Station-Id, but only for a specific huntgroup. Is that possible with FreeRADIUS? Thanks, Felician Hoppal
