Implementing FUP with FreeRadius and Mikrotik
by Randeep 23 Jun '15

23 Jun '15

Hi, We are doing the implementation with FreeRadius+mysql+mikrotik. for a starter plan we have 30G usage limit @4mbps(d)/4mbps(u). After this limit, we need to scale down the speed to @2mbps(d)/2mbps(u). I have configured Mikrotik-Rate-Limit = '4096k/4096k' Is it mandatory to give the burst rates and burst time? Does it really help? And once the 30G is reached I need to send Mikrotik-Xmit-Limit Mikrotik-Recv-Limit In a pre-auth condition right? But I am confused with the following: Mikrotik-Recv-Limit-Gigawords Mikrotik-Xmit-Limit-Gigawords I read about it. But I'm not getting the thing 32 bit and 64 bit. Maximum 4G limit we can give? Can someone help me on this. -- Best Regards, Randeep Mob: +919447831699[kerala] Mob: +919880050349[B'lore] http://twitter.com/Randeeppr http://in.linkedin.com/in/randeeppr [image: --] Randeep Raman [image: http://]about.me/Randeeppr <http://about.me/Randeeppr>

Assigning ip address (FreeRadius or NAS)
by Randeep 23 Jun '15

23 Jun '15

Hi, I have a question please help. We have configured IP Pool. And the radius is sending the ip and other information. [root@localhost ~]# radtest randeep randeep123 192.168.1.182 0 lukup124 Sent Access-Request Id 70 from 0.0.0.0:38745 to 192.168.1.182:1812 length 77 User-Name = 'randeep' User-Password = 'randeep123' NAS-IP-Address = 127.0.0.1 NAS-Port = 0 Message-Authenticator = 0x00 Cleartext-Password = 'randeep123' Received Access-Accept Id 70 from 192.168.1.182:1812 to 0.0.0.0:0 length 86 Framed-Protocol = PPP Framed-IP-Netmask = 255.255.255.0 Framed-MTU = 1500 Framed-Routing = Broadcast-Listen Framed-Compression = Van-Jacobson-TCP-IP Service-Type = Framed-User MS-Primary-DNS-Server = 8.8.8.8 MS-Secondary-DNS-Server = 8.8.4.4 Framed-IP-Address = 192.168.1.39 [root@localhost ~]# But in this it is telling the NAS to give the IP 192.168.1.39 to the client right? NAS should have PPPoE / DHCP running in that right? Also the Private IP to Public IP nating also will happen on the NAS right? Can someone please explain how it works in the production environment Best Regards, Randeep

Unknown module "clients"
by Stefano Zanmarchi 23 Jun '15

23 Jun '15

Hello, I'm performing some filtering, based on the client, in the authorize section of inner-tunnel: authorize { preprocess rewrite.calling_station_id if ("%{clients:shortname}" =~ /internal_radius_(.*)/i) { ok update control { Auth-Type := Accept } } ... } The output logs in debug mode show the following warning: .. ++? if ("%{clients:shortname}" =~ /internal_radius_(.*)/i) WARNING: Unknown module "clients" in string expansion "%" .. Does this mean that the 'if ("%{clients:shortname}"...' clause is not being evaluated? How can I solve the problem generating the warning? Thank you, Stefano

Service-Type
by Randeep 23 Jun '15

23 Jun '15

Hi, What is the actual use of Service-Type. For PPP we need to give Service-Type = Framed-User and for hotspot we need to give Service-Type = Login ? Also the usergroupreply parameters for PPP and Hotspot will be same or we need to specify separate? Please advice. -- Randeep Mob: +919447831699[kerala] Mob: +919880050349[B'lore] http://twitter.com/Randeeppr http://in.linkedin.com/in/randeeppr [image: --] Randeep Raman [image: http://]about.me/Randeeppr <http://about.me/Randeeppr>

Logrotate for FreeRadius 3.0.8
by Sunil Kulkarni -X (sunikulk - PERSISTENT SYSTEMS INC at Cisco) 23 Jun '15

23 Jun '15

Hello All, I am using FreeRadius 3.0.8. To setup the log rollover, I did the following steps. 1. Copy the attached radius file into /etc/logrotate.d/radius 2. Attached radius file contains information about the log. I am expected logrotate will create a log file on daily basis, because global setting in radiusd file is daily. But log file is not created on daily basic. When I have executed radiusd forcefully using logrotate -v -f /etc/logrotate.d/radiusd command. It is created compressed file and create a new log for logging. Am I missing anything in configuration? --- Thanks, Sunil Kulkarni

Authenticate to LDAP with GSSAPI
by William 22 Jun '15

22 Jun '15

Hi, I have researched this topic and am unable to find examples or previous mailing lists queries about this specific issue. My issue is NOT using GSSAPI/krb5 to authenticate users and LDAP for user details. I have LDAP for authentication and user details with EAP, but I wish for the radiusd ldap connections to authenticate to the ldap server with GSSAPI (IE keytab / service account). The equivalent commands in userspace is: ldapsearch -Y GSSAPI '(objectClass=*)' I am unable to find references in the documentation as to how to achieve this. For example my current setup is: mods-enabled/ldap ldap { # ... snip ... identity = "krbprincipalname=radius/example.com,cn=services,cn=accounts,dc=example ,dc=com" password = foo } I would hopefully aim to have something akin to: ldap { # ... snip ... identity = "krbprincipalname=radius/example.com,cn=services,cn=accounts,dc=example ,dc=com" krb5_keytab = /etc/raddb/krb5.keytab krb5_principal = radius/example.com } Or even a combination of the keytab settings in mods-enabled/krb5 and mods-enabled/ldap. Does anyone have any experience with such configuration or whether freeradius supports the behaviour I would like to achieve? Sincerely, William

Setting up centralized authentication for Linux SSH users
by Daniel Bray 22 Jun '15

22 Jun '15

I'm starting to wonder if I've selected the wrong tool for the job here. Hoping to gather some guidance, and help. The environment is 99% Linux servers with various Cisco equipment. I was thinking that a Freeradius solution would be a simple approach to get all the SSH devices (Linux and Cisco) pointing to a single server for authentication purposes. I would also like to setup groups, so that our Vendors that also require SSH access can be setup and assigned to specific groups that then can only SSH into specific servers. Am I heading in the right direction by selecting Freeradius to do this job? Here comes the issues I face. I got everything setup on a Linux server, and using MySQL as the backend. I'm also using daloRADIUS as the web frontend for management. I was able to get the test Linux servers PAM configured to point to the Freeradius server, and I can authenticate myself, and the other admins. However, it appears that, by default, all users can SSH into any of the NAS devices I've configured. This is the main issues I'm trying to solve. How, exactly, do I configure Freeradius to only allow certain vendor accounts SSH access into specific NAS devices? Thank you

FR3 and EAP-TLS session cache
by Jyri Palis 22 Jun '15

22 Jun '15

Hi, I have been trying to get FR (3.0.4) EAP-TLS session caching to work with ‘check-eap-tls’ virtual server, so far no luck. Initial EAP-TLS session is established correctly and Windows 7 clients get access to protected WLAN but requests following initial request fail to utilise data stored TLS session cache data client is force to proceed with full TLS handshake. Virtual server 'check-eap-tls’ which is configured to verify client certificates fails when cached TLS session calls this method, variables needed for verification are not propagated correctly. server check-eap-tls { authorize { if ("%{TLS-Client-Cert-Subject-Alt-Name-Upn}" =~ /^([a-z0-9]|[\w\.-]?)+\(a)example\.com$/i) { update config { Auth-Type := Accept } } elsif ("%{TLS-Client-Cert-Subject-Alt-Name-Dns}" =~ /^([a-z0-9]|[\w\-]?)+\.example\.com$/i) { update config { Auth-Type := Accept } } else { update config { Auth-Type := Reject } } } This is a fragment from log file: Sun Jun 14 14:56:11 2015 : Auth: (44) Login incorrect (eap: Failed continuing EAP TLS (13) session.
