how to use radius server return some custom error message.

RouterOS General
1

We are using MT HotSpot.

I need to use radius server return some custom error message.

But I didn't find the right radius-reply Attribute of MT.

I only found MIKROTIK Radius Attributes here:

PS:The error.txt of MT hotspot have a definition:

Radius server returned some custom error message

radius-reply = $(error-orig)

http://freeradius.org/rfc/rfc2865.html#Reply-Message
It’s a default attribute. No vendor, type 18.

and how to use in radius ??? :open_mouth:

I did see the issue posted previously but one of the MT guys that the issue was acknowledged (radius attributes not being displayed on the login page) and would be fixed in ROS v4.4.

Mikrotik sergejs replied value like this : $(radius3-18)

I use FreeRADIUS, so take that into account.

Insert the message into the radius MySQL database in the radreply table. I don’t know how your software does that, so hopefully you will know that already.

UserName ‘username’
Attribute ‘Reply-Message’
op ‘=’
Value ‘your message here’

I think it is the variable $(error) on the login page.

ADD: Confirmed it is $(error). It should display on the login page by default if the user login fails.
