Changes to safe-characters list not honoured
by Jack Patmos 31 May '12

31 May '12

Hi, I am using FreeRADIUS 2.1.10 to write accounting data to a postgres database. The usernames are email addresses and therefore might contain characters that are not included in the default safe-characters list (for example, '+'). I am also writing user-agents, which contain other characters not in the default list. I have modified the safe-characters list in the DB conf for that server and the logs suggest that this change has been picked-up, but when I fire some test packets at the server with radclient I find that the additional characters are still being escaped. I have also tried making the same change in sql/postgres/dialup.conf, but this does not work either. Excerpts from config and logs are below. Where am I going wrong with this? Thanks, Jack P.

Radius Server stuck and stop responding.
by Awais 31 May '12

31 May '12

We are using radius server for IPTV services. It was running fine but 2 days before it stuck and stop responding. But after restart it is working fine now, i want to know what may be the problem because of which it stuck and stop responding. It is on trail so they want to know the reason. It will also help me in future to remove that bug. -- View this message in context: http://freeradius.1045715.n5.nabble.com/Radius-Server-stuck-and-stop-respon… Sent from the FreeRadius - User mailing list archive at Nabble.com.

more EAP/TTLS trouble
by Steve Hopps 30 May '12

30 May '12

The only computer in our office which causes certificate errors is a Windows 7 machine. So I attempted to connect using EAP/TTLS and MSCHAPv2 using my linux machine and my Android phone. Now I get a different error. I also tried using PEAP on my Android phone, and received no certificate errors. What could the windows machine be doing different? Why does the machine even enter the picture when the authentication is between the Access Point and the server? Below is the portion of the log which shows the rejection, when using my Android phone, TTLS and MSCHAPv2 (that is what Windows uses isnt it?) Where I am confused is near the bottom, what is causing the rejection? ++[pam] returns invalid or [eap] Handler failed in EAP/ttls [eap] Failed in EAP select ++[eap] returns invalid log follows---- server inner-tunnel { # Executing section authorize from file /etc/freeradius/sites-enabled/inner-tunnel +- entering group authorize {...} ++[chap] returns noop [suffix] No '@' in User-Name = "test", looking up realm NULL [suffix] No such realm "NULL" ++[suffix] returns noop ++[control] returns noop [eap] No EAP-Message, not doing EAP ++[eap] returns noop [files] users: Matched entry DEFAULT at line 222 ++[files] returns ok ++[expiration] returns noop ++[logintime] returns noop ++[pap] returns noop WARNING: You set Proxy-To-Realm = LOCAL, but the realm does not exist!

RE: more EAP/TTLS trouble

Hi Steve Microsoft supports EAP TTLS in our upcoming is release of Windows 8 . That said PEAP MSChapv2 is as modern as an EAP TTLS and is a very widely and simply deployed method. I have personally used the freeradius peap mschapv2 pretty much out of the box. As far as the certificate error you saw earlier that was due to the nature of design of a modern secure authentication method which gave supported security feature like Server Certificate Validation enabled by default. If you just go through the net you will find tonnes of peap mschapv2 working eap.conf's and I suggest you compare yours to the ones available for the authentication to work. Also if you are looking for ttls only you can test with the beta of windows 8 and become one of our early adopters when it releases. Thanx and Regards Aman Arneja Sent from my Windows Phone ------------------------------ From: Steve Hopps Sent: 5/30/2012 6:23 PM To: FreeRadius users mailing list Subject: Re: more EAP/TTLS trouble We're trying to use an access point configured for wpa2 using freeradius to authenticate with openldap. For Android and Linux it works out of the box with eap/ttls and pap. So we used Pam cause it already works with ldap. I didn't know other encryption types wouldn't work with Pam. IPhones work with a custom config profile that's easily installed. However, our most significant hurdle is windows machines. Who would have guessed??? For some stupid reason Microsoft doesn't care about supporting all modern encryption standards. Making our staff pay for SecureW2 isn't an option and XSupplicant doesn't work reliably yet in 64bit Win7. So I'm back to trying to get mschapv2 working with peap. This seems impossible.

FreeRadius autoreply the access chanllenge
by sam 30 May '12

30 May '12

I setup the pam_radius_auth.so in pam.d/sshd to verify the user using the remote Radius server. As the protocol, When used in an Access-Challenge, it MAY indicate a dialog message to prompt the user for a response. like following flow 1) server sends the access-challenge message with reply-message YOUR PASSWORD HAS EXPIRED. PLEASE ENTER THE NEW PASSWORD 2) client sedns back the access-Request message. 3) server sends another access-challenge message with reply-message PLEASE RE-ENTER THE NEW PASSWORD AGAIN FOR VERIFICATION 4) client sedns back the access-Request message again. I think the message flow is right, but at the point-2 and point-4, the prompt should be popped and ask us to input the passwd. However, our freeradius sends the access-Request automatically. Just checked the code, and not find the problem when doing access-chanllenge. the function rad_converse() calls pam_get_item(). I think it is only place to suspect, can this function pop the prompt? anyone encounter this problem? /* It's full challenge-response, we should have echo on */ retval = rad_converse(pamh, PAM_PROMPT_ECHO_OFF, challenge, &resp2challenge); +++processing access-chanllenge code+++ while (response->code == PW_ACCESS_CHALLENGE) { attribute_t *a_state, *a_reply; char challenge[BUFFER_SIZE]; /* Now we do a bit more work: challenge the user, and get a response */ if (((a_state = find_attribute(response, PW_STATE)) == NULL) || ((a_reply = find_attribute(response, PW_REPLY_MESSAGE)) == NULL)) { /* Actually, State isn't required. */ _pam_log(LOG_ERR, "RADIUS Access-Challenge received with State or Reply-Message missing"); retval = PAM_AUTHINFO_UNAVAIL; goto error; } /* * Security fixes. */ if ((a_state->length <= 2) || (a_reply->length <= 2)) { _pam_log(LOG_ERR, "RADIUS Access-Challenge received with invalid State or Reply-Message"); retval = PAM_AUTHINFO_UNAVAIL; goto error; } memcpy(challenge, a_reply->data, a_reply->length - 2); challenge[a_reply->length - 2] = 0; DPRINT(LOG_DEBUG, "Got Prompt=%s",challenge); /* It's full challenge-response, we should have echo on */ retval = rad_converse(pamh, PAM_PROMPT_ECHO_OFF, challenge, &resp2challenge); <<<<< here /* now that we've got a response, build a new radius packet */ build_radius_packet(request, user, resp2challenge, &config); /* request->code is already PW_AUTHENTICATION_REQUEST */ request->id++; /* one up from the request */ /* copy the state over from the servers response */ add_attribute(request, PW_STATE, a_state->data, a_state->length - 2); retval = talk_radius(&config, request, response, resp2challenge, NULL, 1); PAM_FAIL_CHECK; DPRINT(LOG_DEBUG, "Got response to challenge code %d", response->code); } +++code+++ +++log+++ May 28 23:12:13 sshd[20729]: pam_radius_auth: Sending RADIUS request code 1 May 28 23:12:13 sshd[20729]: pam_radius_auth: DEBUG: getservbyname(radius, udp) returned -745295136.

rlm_python configTuple question
by PENZ Robert 30 May '12

30 May '12

Hi! The python functions should return (return, replyTuple, configTuple). return is one of the following constants #RLM_MODULE_REJECT = 0 # /* immediately reject the request */ #RLM_MODULE_FAIL = 1 # /* module failed, don't reply */ #RLM_MODULE_OK = 2 # /* the module is OK, continue */ #RLM_MODULE_HANDLED = 3 # /* the module handled the request, so stop. */ #RLM_MODULE_INVALID = 4 # /* the module considers the request invalid. */ #RLM_MODULE_USERLOCK = 5 # /* reject the request (user is locked out) */ #RLM_MODULE_NOTFOUND = 6 # /* user not found */ #RLM_MODULE_NOOP = 7 # /* module succeeded without doing anything */ #RLM_MODULE_UPDATED = 8 # /* OK (pairs modified) */ #RLM_MODULE_NUMCODES = 9 # /* How many return codes there are */ replyTuble are the attributes which are send to the requesting NAS, but I couldn't find out what configTuple is exactly. I currently only pass an () and it works. Is it the same as "update control" and setting variables in the normal config files? What I would like to do is to provide a variable which can be used in the config file after calling the python module to compare it against "%{TLS-Client-Cert-Subject}" as I don't see a possible to get this variable in the python module to do the compare there.
