Sending NAS-IP-Address to inner-tunnel
by Gary Gwin 23 Feb '18

23 Feb '18

I have the need to send the NAS-IP-Address to the inner-tunnel, which by default only receives the FreeRADIUS-Proxied-To. Here's what is received with the Access-Request: (7) Received Access-Request Id 0 from 74.174.75.20:55809 to 10.13.0.251:1812 length 198 (7) User-Name = "tomas(a)acme.com" (7) NAS-IP-Address = 75.174.238.20 And here's what is sent to the inner-tunnel: (7) eap_peap: Sending tunneled request to inner-tunnel (7) eap_peap: EAP-Message = 0x0207001701746f6d6173406f6e656c6f67696e2e636f6d (7) eap_peap: FreeRADIUS-Proxied-To = 127.0.0.1 (7) eap_peap: User-Name = "tomas(a)acme.com" And here's what the inner-tunnel recieves: (7) Virtual server inner-tunnel received request (7) EAP-Message = 0x0207001701746f6d6173406f6e656c6f67696e2e636f6d (7) FreeRADIUS-Proxied-To = 127.0.0.1 (7) User-Name = "tomas(a)acme.com" Is there a way to send the NAS-IP-Address to the inner-tunnel? Thanks, Gary

rlm_detail and empty packets
by Brian Candler 22 Feb '18

22 Feb '18

I was trying to find out why reply_log wasn't logging successful authentications [freeradius 3.0.x] It turns out there is hard-coded logic in rlm_detail.c to ignore packets which don't contain any AV pairs: if (!packet->vps) { RWDEBUG("Skipping empty packet"); return 0; } This is unfortunate because I was hoping to see e.g. Thu Feb 22 13:53:29 2018 Packet-Type = Access-Accept Timestamp = 1519307609 I can force it to work by adding a spurious Reply-Message attribute, but that seems silly. Setting "log_packet_header" doesn't make any difference, because the empty packet check is made very early on. Was there a reason for suppressing these logs? Would it be worth having a config switch for this? Regards, Brian.

FreeRadius Re-Authentication Latency
by Smith, James 21 Feb '18

21 Feb '18

Submitted as a larger email last time. The attached file is now compressed and email should be a smaller size. Hello, I'm currently experiencing a latency issue with Siemens base stations and CPEs re-authenticating to our FreeRadius server running version 3.0.4. (I understand this version is a little old and should be updated. We will look into this in the new future) Attached is my log file after running FreeRadius in debug mode. CPE9(a)siemens.com is the specific host I'd like to look at but all of our CPEs are experiencing the same issue. We use EAP-TTLS for authentication and it looks like it takes many sessions (167 from what I can tell by looking at the Access-Request ID) to actually complete the re-authentication process. The amount of sessions may vary for each CPE as they can take 2-10 minutes to actually authenticate. It starts on line 3546 and finally authenticates on line 18927. CPE (Suplicant) ----> NAS-Identifier = "BS" (Authenticator) ------> Radius Server Please let me know if you have any questions and/or if you think I have to tweak my configuration somewhere to speed this up.

Custom, conditional, variable in linelog
by Giuseppe Civitella 19 Feb '18

Hi all, I use a few virtual servers to define users access to CISCO devices against their LDAP profile. In every virtual server I've got: post-auth { update { &reply: += &session-state: } reply_log exec if ("%{ldap:ldap://127.0.0.1/USER_DN?objectClass?one?(&(dialupAccess=yes)(o=cpe_mpls_15)(cn=%{User-Name}))}") { update reply { &Reply-Message += 'Custom message' &Cisco-AVPair += 'shell:priv-lvl=15' My-Ldap-filter := cpe_mpls_15 } } log_dyn_clients In my local dictionary I defined: ATTRIBUTE My-Ldap-filter 5000 string I'd like to assign a value to My-Ldap-filter in every if block and record the value in a log file. So i defined log_dyn_clients this way: linelog log_dyn_clients { filename = ${logdir}/linelog-client-auth-%Y%m%d.log permissions = 0600 reference = "messages.%{%{reply:Packet-Type}:-default}" messages { default = "[Unknown] unknown packet type %{Packet-Type}" Access-Accept = "[Accept] user: %{User-Name}, client_ip: %{Packet-Src-IP-Address}, virtual_server: %{Virtual-Server}, attr: %{My-Ldap-filter}" Access-Reject = "[Reject] user: %{User-Name}, client_ip: %{Packet-Src-IP-Address}, virtual_server: %{Virtual-Server}, attr: %{My-Ldap-filter}" } } Unfortunately I'm not able to get My-Ldap-filter's value in the logs: [Accept] user: gcivitella, client_ip: 10.200.20.79, virtual_server: cpe_mpls_srv, attr: [Accept] user: gcivitella, client_ip: 10.200.20.79, virtual_server: cpe_mpls_srv, attr: How could I get the logs I need? Any idea? Thanks a lot, Giuseppe

Re: Salted SHA3 Support
by Rashad Hall 16 Feb '18

16 Feb '18

Currently running FreeRADIUS Version 3.0.15 and looking for confirmation of SHA3 support as I found this page (https://freeradius.org/radius d/man/rlm_pap.html) that has SHA3 listed, but when I run man rlm_pap I have significantly fewer options. Just wanted to confirm if support for SHA3 in FreeRADIUS is available yet? My "man rlm_pap" below. rlm_pap(5) FreeRADIUS Module rlm_pap(5) NAME rlm_pap - FreeRADIUS Module DESCRIPTION The rlm_pap module authenticates RADIUS Access-Request packets that contain a User-Password attribute. The module should also be listed last in the authorize section, so that it can set the Auth-Type attribute as appropriate. When a RADIUS packet contains a clear-text password in the form of a User-Password attribute, the rlm_pap module may be used for authentication. The module requires a "known good" password, which it uses to validate the password given in the RADIUS packet. That "known good" password must be supplied by another module (e.g. rlm_files, rlm_ldap, etc.), and is usually taken from a database. CONFIGURATION The only configuration item is: normalise The default is "yes". This means that the module will try to automatically detect passwords that are hex- or base64-encoded and decode them back to their binary representation. However, some clear text passwords may be erroneously converted. Setting this to "no" prevents that conversion. USAGE The module looks for the Password-With-Header control attribute to find the "known good" password. The attribute value comprises the header followed immediately by the password data. The header is given by the following table. Header Attribute Description ------ --------- ----------- {clear} Cleartext-Password clear-text passwords {cleartext} Cleartext-Password clear-text passwords {crypt} Crypt-Password Unix-style "crypt"ed passwords {md5} MD5-Password MD5 hashed passwords {base64_md5} MD5-Password MD5 hashed passwords {smd5} SMD5-Password MD5 hashed passwords, with a salt {sha} SHA-Password SHA1 hashed passwords SHA1-Password SHA1 hashed passwords {ssha} SSHA-Password SHA1 hashed passwords, with a salt SSHA1-Password SHA1 hashed passwords, with a salt {ssh2} SHA2-Password SHA2 hashed passwords {ssh256} SHA2-Password SHA2 hashed passwords {ssh512} SHA2-Password SHA2 hashed passwords {nt} NT-Password Windows NT hashed passwords {nthash} NT-Password Windows NT hashed passwords {x-nthash} NT-Password Windows NT hashed passwords {ns-mta-md5} NS-MTA-MD5-Password Netscape MTA MD5 hashed passwords {x- orcllmv} LM-Password Windows LANMAN hashed passwords {X- orclntv} LM-Password Windows LANMAN hashed passwords *--* *Rashad Hall* Jr. Network Engineer | *Zayo Group* O: +1 858.836.0202 <(858)%20836-0202> 12270 World Trade Drive Suite #100 | San Diego, CA 92128 Mission <http://www.zayo.com/company/about-zayo/> | Network Map <http://www.zayo.com/solutions/global-network/> | LinkedIn <https://www.linkedin.com/company/zayo-group> | Twitter <https://twitter.com/zayogroup>
