Store session on mysql
by michel＠casa.co.cu 02 Oct '09

02 Oct '09

Hello I currently work with the version 2.1.6 without any problem, session of my users are stored in the file "radutmp. I would store them at the same time in mysql, is this possible? Is there any page where this is documented? I want to make a script for my squid server then checks against mysql search if the user is connected, compare against a file if it exists in that list, take the IP address that you assign and freeradius in the squid allows internet access. Suggestions? Greetings Michel ---------------------------------------------- Webmail, servicio de correo electronico Casa de las Americas - La Habana, Cuba.

Bug in create-users.pl
by Jens Link 02 Oct '09

02 Oct '09

Hi all, just one quick question: Michael Schwartzkopff reported a bug in create-users.pl in Febuary 2009. As I'm just preparing a presentation on freeRADIUS I noticed that this still isn't fixed. Any plans on when it will be fixed?

Re: Identity does not match User-Name, setting from EAP Identity

> I have a username and identity in EAP attribute with pattern > {m=1}xxxx@xxxx. > I need to remove {m=1} for both username and identity in EAP attribute. > I put some regular expression in default file authorize section to > remove {m=1} for username and it works! > But I have not found a way to remove {m=1} for identity in EAP packet. The whole point of EAP is that you - can't. You can't alter username without breaking EAP. The best you can do is to define prefix type realm in raddb/modules/realm with ) as delimiter and local realm (m=1 in proxy.conf. That should leave the rest as Stripped-User-Name.

radiusd is already running on that port. When checking /etc/rc.d/rc3.d I found a file named "S88radiusd". I thought that the "Address already in use" error was supposed to happen if trying to start a second instance of the same service? -- Paul Blalock

Radius is *not* under Startup Applications. Yes, sorry, I did not stop the service then run Radiusd -X, but I have now, and this is what I get.

I should have been logged in as root, but not sure. -- Paul Blalock

pam_radius_auth.c memory leaks?
by Cesare Placanica 01 Oct '09

01 Oct '09

Hi, I've written a little test application for pam_radius_auth. Although in the following article: http://developers.sun.com/solaris/articles/user_auth_solaris3.html is written that *pam service modules are in charge of freeing pam_response messages*, I suspect that this is not happening. Here is my test application and the memory debug using libumem: gerace:1> ldd check_user libpam.so.1 => /usr/dt/lib/libpam.so.1 libumem.so.1 => /lib/libumem.so.1 libc.so.1 => /lib/libc.so.1 libcmd.so.1 => /lib/libcmd.so.1 libm.so.2 => /lib/libm.so.2 /platform/SUNW,A70/lib/libc_psr.so.1 gerace:2> uname -a SunOS gerace 5.10 Generic_118833-03 sun4u sparc SUNW,A70 gerace:3> gerace:3> cat check_user.c #include <sys/types.h> #include <unistd.h> #include <pwd.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #include <security/pam_appl.h> #include "dprint.h" /* pam conversation function */ extern int check_conv(int num_msg, struct pam_message **msg, struct pam_response **resp, void *app_data); int main(int argc, char *argv[]) { struct pam_conv conv = { check_conv, NULL }; pam_handle_t *ph; int error; if (argc == 1) { printf("pam_radius_auth testing utility\n\n"); printf("Usage: %s user [trace_flag (0|1)]\n", argv[0]); exit(0); } if (argc == 3) { if (0 == strncmp(argv[2], "1", 2)) { trace_flag = 1; } } if ((error = pam_start("ctms", argv[1], &conv, &ph)) != PAM_SUCCESS) { fprintf(stderr, "Call to pam_start failed: %s\n", pam_strerror(ph, error)); exit(1); } for (;;) { error = pam_authenticate(ph, 0); if (error == PAM_SUCCESS) { printf("Password match.\n"); break; } else { if (error == PAM_AUTHINFO_UNAVAIL) { printf("Server down\n"); break; } else { printf("Password don't match.\n"); } } } pam_end(ph, 0); return (0); } gerace:4> gerace:4> cat check_user_conv.c #include <sys/types.h> #include <unistd.h> #include <pwd.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #include <security/pam_appl.h> #include "dprint.h" int check_conv(int num_msg, struct pam_message **msg, struct pam_response **resp, void *app_data) { struct pam_message *m = *msg; struct pam_response *r; int i; char *ct_passwd = NULL; char *ct_pin = NULL; DPRINT("DEBUG: entering conversation function\n"); if ((num_msg <= 0) || (num_msg >= PAM_MAX_NUM_MSG)) { fprintf(stderr, "Invalid number of messages\n"); *resp = NULL; return (PAM_CONV_ERR); } if ((*resp = r = calloc(num_msg, sizeof(struct pam_response))) == NULL) return (PAM_BUF_ERR); for (i = 0; i < num_msg; i++) { switch (m->msg_style) { case PAM_PROMPT_ECHO_OFF: if (m->msg) { DPRINT("DEBUG: PAM_PROMPT_ECHO_OFF server says %s\n", m->msg); } else { DPRINT("DEBUG: PAM_PROMPT_ECHO_OFF\n"); } ct_passwd = getpassphrase("Enter password: "); r->resp = strdup(ct_passwd); m++; r++; break; case PAM_PROMPT_ECHO_ON: DPRINT("DEBUG: PAM_PROMPT_ECHO_ON\n"); if (m->msg) { ct_pin = getpassphrase(m->msg); r->resp = strdup(ct_pin); } else { r->resp = NULL; } m++; r++; break; case PAM_ERROR_MSG: DPRINT("DEBUG: PAM_ERROR_MSG\n"); if (m->msg) fprintf(stderr, "%s\n", m->msg); m++; r++; break; case PAM_TEXT_INFO: DPRINT("DEBUG: PAM_TEXT_INFO\n"); if (m->msg) printf("%s\n", m->msg); m++; r++; break; } } return (PAM_SUCCESS); } gerace:6> gerace:6> gerace:6> setenv LD_PRELOAD libumem.so.1 gerace:7> setenv UMEM_DEBUG default gerace:8> sudo mdb ./check_user > ::sysbp _exit > ::run SuperUser Enter password: Password match. mdb: stop on entry to _exit mdb: target stopped at: libc.so.1`exit+0x14: ta 8 mdb: You've got symbols!

The second leak is the calloc in check_conv function. There is a guideline to handle this memory issues for pam_response messages? Regards, Cesare

Dear all, I posted this problem a week ago after searching in posted and solved emails like here ( http://www.mail-archive.com/search?q=rlm_ldap&l=freeradius-users@lists.cist… ). I have already asked but the answers were not effective... Anyway, I d like to express my gratitude to those who have tried to read and respond to my problems ! So I m asking myself if : Using LDAP with freeradius is it something new or something? My problem is about the ldap library for freeradius (libldap which is needed by rlm_ldap) ... What should I do to install and configure it 'cause it's not in the freeradius-server package(I rebuilt it 5 times and I paid attention to the output? If I ll receive the same answers I received before then maybe the problem is in my operating system(CentOsV5.3) Thanks to all ... Best regards ... NB: I am fed up of this buuuuuuuuuuuuug! Neeed help! -- JJohnny RANDRIAMAMPIONONA Phone: +212663682554, +212533158575 National School of Applied Sciences ZIP 1818 TANGIER 90000 ---------Morocco ---------------

Rlm_ldap not found
by Leighton Man 01 Oct '09

Hi all, Hope this is an easy one: Freeradius 2.1.6 on arch linux installed from a package. All is well until I uncomment ldap in the authorise section of sites-enabled/inner-tunnel then I get: /etc/raddb/modules/ldap[29]: Failed to link to module 'rlm_ldap': file not found followed by Failed to find module "ldap" ...... rlm_ldap.so is a symlink to rlm_ldap-2.1.6.so which has the same permissions and is in the same directory as the other modules which load OK (they are also symlinks in the same directory). I've checked for typos until I'm beginning to see them even when they are not there! Radiusd -X shows no errors or warnings and after the ***Loading Virtual Servers**** message continues linking and instantiating modules up to and including "files" then the error above. Not easy to post the whole output as I haven't got ftp running yet. Where should I look next? Regards, Leighton --- This transmission is confidential and may be legally privileged.
