Some notes though: (1) the option "filename" in ISC's dhcp should refer to pxe boot image, something like host clientname { filename "/tftpboot/tftpboot.img"; ... } If your system is x86, and the OS/kernel loaded is linux or can be booted with multiboot (e.g. solaris), then usually you can just use pxelinux in "filename" option. pxelinux can then load the correct config file for each host using a host-specific configuration file (based on the hosts' MAC or IP address), or it can load the default config file: http://www.syslinux.org/wiki/index.php/PXELINUX Are you sure you're actually using per-host filename option instead of a common one? (2) I tested by adding this block in FR's DHCP-Discover and DHCP-Request section: update reply { DHCP-Boot-File-Name = "/boot/pxelinux.0" } it works as expected. The attribute is sent to all hosts requesting DHCP address, but only hosts doing network boot will acttually use it. A cleaner approach would probably be checking if the client sends DHCP-Parameter-Request-List = DHCP-Boot-File-Name ... and only send the reply then. -- Fajar

Authenticating Laptop without a Certificate Installed
by McSparin, Joe 25 Jan '12

25 Jan '12

When I connect a mobile phone or a tablet to my wireless network it works fine even though they don't have a certificate installed. I am checking the MAC address and putting them into a public vlan if it is not found. However when I connect a windows laptop that does not have a certificate installed it doesn't allow it. It won't connect and radius says it has an unknown CA I am using PEAP which it is my understanding would allow you to connect with a user name and password and no certificate if you told it not to validate the certificate. It is important that people be able to connect even if they don't have a certificate and I just control it based on the mac address.

Juniper MX auth issue
by Paul Stewart 24 Jan '12

24 Jan '12

Hi there.. We have an existing FreeRadius setup that works perfectly for our Cisco BRAS devices etc. I am trying to get some Juniper MX working properly. If I add a user to our system it works fine (dynamic IP assignment etc). The minute we add a static IP address, things go weird with the MX platform. The user authenticates and obtains the correct IP address but no traffic will pass. JTAC says this is an attributes related issue and we are back and forth. I was hoping someone on the list here could correct by users entry below based on their experiences? I'm running a fairly bare set of attributes hoping to figure out why this keeps breaking on the Juniper side: pstewart Auth-Type = System Service-Type = Framed, Framed-Protocol = PPP, Framed-IP-Address = xxx.xxx.111.73 Our typical users entry that works fine in the Cisco world looks like this: pso Auth-Type = System Service-Type = Framed-User, Framed-IP-Address = xx.xxx.58.115, Framed-MTU = 1500, Idle-Timeout = 11116000 So far I have messed around with many variables and not getting it to work properly.. At the same time JTAC has been quite helpful but we're still not operational yet. Thanks, Paul

Next release of the server?
by Alan DeKok 24 Jan '12

24 Jan '12

It's been 4 months since the last release of the server. Any objections to a new release? Are people using the v2.1.x branch in "git"? My idea would be to release this version as 2.2.0. It's stable, and doing 2.2.0 would probably be better than 2.1.13. :) I'd also like to release 3.0 in the next few months. I know I've been saying that for a while. The delays have been due to some intended design changes which haven't yet been implemented. As background, the RADIUS protocol encoder/decoder has changed to its final form in 3.0. It does more with less code, and is easier to understand. I don't think it will change again. Similarly, the state machine for handling packets has been updated in 3.0. It's a lot better than 1.x or 2.x, but it's not quite done yet. The hope is that I can do some small changes for 3.0 which will finalize the internal state machine. That will make it easier to separate the RADIUS, DHCP, and VMPS functionality in the server. It will also mean that certain new features will be easier to add. :) Alan DeKok.

Freeradius + Mysql + PEAP Authentication
by RAZAFIMBELO Faliharinohatra Rindra 24 Jan '12

24 Jan '12

Hi all, I have configured a freeradius + mysql server and i would like to use the PEAP authentication. I have tried the EAP-TTLS and it worked fine, but when i have tested the PEAP authentication all my requests were rejected by freeradius. I saw that both of PEAP and EAP-TTLS used TLS and i thought that there was no need to make big configuration to migrate from EAP-TTLS to PEAP. Can someone help me, please? I use freeradius 2.1.10 and here is my eap.conf configuration: eap { default_eap_type = ttls timer_expire = 60 ignore_unknown_eap_types = no cisco_accounting_username_bug = no max_sessions = 4096 md5 { } leap { } gtc { auth_type = PAP } tls { certdir = ${confdir}/certs cadir = ${confdir}/certs private_key_password = madaoil452 private_key_file = ${certdir}/server.key certificate_file = ${certdir}/server.pem CA_file = ${cadir}/ca.pem dh_file = ${certdir}/dh random_file = /dev/urandom CA_path = ${cadir} cipher_list = "DEFAULT" cache { enable = no max_entries = 255 } verify { } } ttls { default_eap_type = md5 copy_request_to_tunnel = no use_tunneled_reply = no virtual_server = "inner-tunnel" } peap { default_eap_type = mschapv2 copy_request_to_tunnel = no use_tunneled_reply = no virtual_server = "inner-tunnel" } mschapv2 { } } thx --

Using sql and userfile together
by Krzysztof Grobelak 24 Jan '12

24 Jan '12

Hello all, I just wanted to ask how could I make FR to use either users file or sql to send attributes based on the NAS ip address. I suspect that I would need to use ulang for that. Something like: if(NAS-IP-Address == NAS A IP) { use sql } else { use users file } I'm just wondering what is the proper syntax of making FR use sql or user file. Kind regards, Krzysztof

LDAP Group assign to vlan after AD user authentication
by James 24 Jan '12

24 Jan '12

Hi, I've successfully set up a radius server to support 802.1x authentication using peap mschapv2 and samba to authenticate users against AD. To do this I followed configuration on the freeradius.org website and the AD integration howto on deployingradius.com, thank you very much for writing these! I now need to assign the vlan due to membership of some group in AD and I understand that an ldap lookup is needed. Where in the configuration do I check this group and map it to a vlan? Can I do it as a default entry in the users file or is it needed somewhere else? Thank you very much, James
