CHAP Method For Radius

alexus

so in freeradius config I have to chane
CHAP{
authentication = chap2
}

or what?

jeroen234

# under MODULES, make sure mschap is uncommented!
mschap {
# authtype value, if present, will be used
# to overwrite (or add) Auth-Type during
# authorization. Normally, should be MS-CHAP
authtype = MS-CHAP

# if use_mppe is not set to no, mschap will
# add MS-CHAP-MPPE-Keys for MS-CHAPv1 and
# MS-MPPE-Recv-Key/MS-MPPE-Send-Key for MS-CHAPv2
#
use_mppe = yes

# if mppe is enabled, require_encryption makes
# encryption moderate
#
require_encryption = yes

# require_strong always requires 128 bit key
# encryption
#
require_strong = yes

authtype = MS-CHAP
# The module can perform authentication itself, OR
# use a Windows Domain Controller. See the radius.conf file
# for how to do this.
}

authorize {
preprocess
mschap
suffix
eap
files
}

authenticate {

#
# MSCHAP authentication.
Auth-Type MS-CHAP {
mschap
}

# Allow EAP authentication.
eap
}

oh ok, so its MS CHAP afterall, let me try that

Thanks!

jeroen234

in youre users file you have this to use chap v1 on windows 95/98 or chap v2 on higher windows versions

"testuser" User-Password == "Secret149"

when you crypt youre passwordts the chap protocol will fail

alexus

Ive edited the config withe the settings you provided, but it still says that username is invalis, aslo for some reason the captive portal doesnt send Auth-Type = MS-CHAP… ?

jeroen234

all captive portals send auth type = local
this is normal
check the bigining of youre users file angainst myne
i think i have atherd there a thing to make vpn and portal working on pfsense

i think it was somfing with system

# DEFAULT entries match with all login names.
# Note that DEFAULT entries can also Fall-Through (see first entry).
# A name-value pair from a DEFAULT entry will _NEVER_ override
# an already existing name-value pair.
#

#
# First setup all accounts to be checked against the UNIX /etc/passwd.
# (Unless a password was already given earlier in this file).
#
#DEFAULT	Auth-Type = System
#	Fall-Through = 1

#
# Set up different IP address pools for the terminal servers.
# Note that the "+" behind the IP address means that this is the "base"
# IP address. The Port-Id (S0, S1 etc) will be added to it.
#
#DEFAULT	Service-Type == Framed-User, Huntgroup-Name == "alphen"
#		Framed-IP-Address = 192.168.1.32+,
#		Fall-Through = Yes

#DEFAULT	Service-Type == Framed-User, Huntgroup-Name == "delft"
#		Framed-IP-Address = 192.168.2.32+,
#		Fall-Through = Yes

#
# Defaults for all framed connections.
#
DEFAULT	Service-Type == Framed-User
	Framed-IP-Address = 255.255.255.254,
	Framed-MTU = 576,
	Service-Type = Framed-User,
	Fall-Through = Yes

#
# Default for PPP: dynamic IP address, PPP mode, VJ-compression.
# NOTE: we do not use Hint = "PPP", since PPP might also be auto-detected
#	by the terminal server in which case there may not be a "P" suffix.
#	The terminal server sends "Framed-Protocol = PPP" for auto PPP.
#
DEFAULT	Framed-Protocol == PPP
	Framed-Protocol = PPP,
	Framed-Compression = Van-Jacobson-TCP-IP

I just looked through the USERS file and it looks exactly the same as yours. I dont know what to do…

jeroen234

oke so system passwords are disabled that is good

start freeradius with
radiusd -x
or with freeradius -x
then try loggin in trouw the portal and look at the error that freeradius is giving in its screen

alexus

yea I am ruuning in the debug mode, and there are no errors, and at the end it says, password is invalid… and it sends Access-Reject
I'm lost now... is there a soft client that send MS-CHAP Access Requests?

alexus

just spoke with people from Mono they say it uses PAP…
hoba, do you know what version of Mono are u using? 1.20 or 1.21?

sullrich

1.21

aldo

it does use pap only.

just add authtpe=pap

in your radius configuration should work depending on your backend it is really no worse than chap.
if you are paranoid and an stunnel from you NAS to your radius backend

alexus

actually I had to use Auth-Type== local, instead of system which is defult… in that case it will fall through all local modules installed
