The file was rlm_exec so file was timestamped 11-01-05 and I know I haven't built anything from source for a long time on that box, so would have to think it was a binary package unless somehow the SuSE update pulls and compiles source on my behalf...I don't think so.

Dialupadmin wont connect to mysql
by Sean Ali 07 Dec '05

07 Dec '05

Hello, I've got Dialupadmin running however when I click through the various menus it keeps telling me that it cannot connect to sql database. This is no surprise to me as I have not setup anything on the mysql side of things for dialupadmin nor have I told dialupadmin what user and password to connect with. My question is where do I go to set the database options? And what, if any, database items do I need to create on the mysql side for it to work? Thanks, Sean.

question on ldap_escape_func in rlm_ldap.c (author: Kostas Kalevras)
by Qin Zhen 07 Dec '05

07 Dec '05

Hi All, I'm new to Radius, now encountered problems with ldap_escape_func in rlm_ldap. please help me since it's really a bit urgent. the comments regarding to this function is 'Add an ldap_escape_func. Escape the * character from the filter so that we can avoid the trivial DoS of username=*'. if i was not wrong, this function intends to filter out the * which follows the username, i.e, if username is 'userid*' in access-request packet, ldapsearch is only based on 'userid'. but what's the purpose for doing this and is it secure? or did i misunderstand the comments? the lastest version freeradius-1.0.5 has a slightly different version for this piece of code, ***************************************************************** freeradius-1.0.5 if (strchr("*=\\,()", *in)) { static const char *hex = "0123456789abcdef"; if (outlen <= 3) break; *(out++) = '\\'; *(out++) = hex[((*in) >> 4) & 0x0f]; *(out++) = hex[(*in) & 0x0f]; outlen -= 3; continue; } ************************************************************** freeradius-1.0.4 and previous if (strchr("*", *in)) { in++; outlen--; continue; } i couldn't figure out what does the change intend to do, is it to filter out '*', '\\', '()' and '=' from username? and why should it be in that way? please help me. thanks a lot in advance.

multiple groups behind one NAS

07 Dec '05

Hi, I have problem with multiple groups behind one NAS after upgrade from freeradius0.9.x to 1.0.4-1. There was no problem with this configuration before upgrade. Scenario: 2 groups: GPRS_1 and GPRS_2 both groups are behind NAS 1.1.1.1 user_1 is member of group GPRS_2 and he and all members of GPRS_2 are rejected. It looks that only members of first group matched in huntgroups file are positive processed. #################### my users file: DEFAULT Huntgroup-Name == DENY, Auth-Type := Reject Reply-Message = "!!!

Re: OS Update broke FR - rlm_exec-1.0.0.so not found
by Landon Cox 07 Dec '05

07 Dec '05

Thanks, Alan. FYI - more research on the topic, I did an ldd on the rlm_exec file: On a freeradius box I have which is working, I did: radius1:/usr/lib/freeradius # ldd rlm_exec-1.0.0.so linux-gate.so.1 => (0xffffe000) libnsl.so.1 => /lib/libnsl.so.1 (0x40018000) libresolv.so.2 => /lib/libresolv.so.2 (0x4002f000) libpthread.so.0 => /lib/tls/libpthread.so.0 (0x40042000) libcrypto.so.0.9.7 => /usr/lib/libcrypto.so.0.9.7 (0x40054000) libssl.so.0.9.7 => /usr/lib/libssl.so.0.9.7 (0x40145000) libc.so.6 => /lib/tls/libc.so.6 (0x40175000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000) libdl.so.2 => /lib/libdl.so.2 (0x4028b000) Then on the radius box I updated and broke I did: radius2:/usr/lib/freeradius # ldd rlm_exec-1.0.0.so linux-gate.so.1 => (0xffffe000) libnsl.so.1 => /lib/libnsl.so.1 (0x55577000) libresolv.so.2 => /lib/libresolv.so.2 (0x5558e000) libpthread.so.0 => /lib/tls/libpthread.so.0 (0x555a1000) libcrypto.so.0.9.7 => /usr/lib/libcrypto.so.0.9.7 (0x555b3000) libssl.so.0.9.7 => /usr/lib/libssl.so.0.9.7 (0x556a4000) libc.so.6 => /lib/tls/libc.so.6 (0x556d4000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x56555000) libdl.so.2 => /lib/libdl.so.2 (0x557ea000) I hunted down and verified that every library that was pointed to by rlm_exec indeed existed on the file system. On both systems, they had everything except both had no linux-gate.so.1. But then radius1 works fine and it shows the same paths and library existence as the radius2 box which fails. Also, googling linux-gate.so.1 I saw: "What is linux-gate.so.1?": http://www.trilithium.com/johan/2005/08/ linux-gate/ and http://kerneltrap.org/node/3405 The first link explains that an ldd report of linux-gate.so.1 that doesn't point to a file/path is normal in recent kernels and goes into detail of what it is. In any case, it's not a problem. After verifying that every library that is pointed to by rlm_exec-1.0.0.so actually exists on both the machine that works fine and the one that doesn't, I understand a little more but don't see what the problem is. There's something else bizarre going on...or perhaps I still need to run ldd on each of the dependent libraries - maybe there's one in that tree of dependencies that's missing. I'll also try going to 1.0.5. Thanks, Landon

attrs file
by Chuck 07 Dec '05

07 Dec '05

I have a need on one of my radius servers to pass every reply attribute my realms I proxy for send up to me regardless of what they are. I then pass these replies upstream. Everything I read describing the default 'realm' in the attrs file mention adding attributes I want to pass on. However in this one instance I would have to list every dictionary attribute. Is there not a way to tell radius to pass everything, maybe with a * on a single line or maybe nothing in the default section? Or must I list every single one? -- Chuck

I'm using FreeRadius (with mysql) to authenticate VPN users on a PIX. I have multiple vpngroups setup on the PIX and want to be able to assign users in the radius database to specific vpngroups on the PIX. For instance, I have a username 'bob' in radcheck (mysql). Bob can use any valid vpngroup (setup on the PIX) and then authenticate (via radius) with his 'bob' username and successfully connect. -- not exactly what I had in mind. Bob should only be able to connect to vpngroup 'usersvpn' and not 'adminsvpn'. I figured there must be an attribute to get this to work? Anyone have any success doing this with a PIX in the picture? __________________________________________ Yahoo! DSL Something to write home about. Just $16.99/mo. or less. dsl.yahoo.com

rlm_counter

Hi, I have Freeradius 1.01 on FreeBSD 5.3. Two questions: 1) Is there a way to show which modules are currently installed? 2) I want to use the rlm_counter module. So I went to /usr/ports/distfiles/freeradius-1.0.1/src/modules/rlm_counter and did a ./configure. That went OK, no errors. I next typed make with the following result: radius# make "../rules.mak", line 65: Missing dependency operator Error expanding embedded variable. I did some googling and found a suggestion that I probably should use gmake on FreeBSD. That bombed also: radius# gmake ../rules.mak:137: warning: overriding commands for target `clean' /usr/ports/distfiles/freeradius-1.0.1/src/main/00-OLD/Make.inc:107: warning: ignoring old commands for target `clean' ../rules.mak:157: warning: overriding commands for target `install' /usr/ports/distfiles/freeradius-1.0.1/src/main/00-OLD/Make.inc:111: warning: ignoring old commands for target `install' gmake: *** No rule to make target `radiusd.c', needed by `radiusd.o'.
