RouterOS v3 Configuration and User Guide
•
Hotspot will ask RADIUS server whether to allow the login or not. If not allowed, alogin.html page
will be displayed (it can be modified to do anything!). If not allowed, flogin.html (or login.html) page
will be displayed, which will redirect client back to the external authentication server.
•
Note: as shown in these examples, HTTPS protocol and POST method can be used to secure
communications.

Possible Error Messages
Description
There are two kinds of errors: fatal non-fatal. Fatal errors are shown on a separate HTML page called
error.html. Non-fatal errors are basically indicating incorrect user actions and are shown on the login
form.
General non-fatal errors:
•
You are not logged in - trying to access the status page or log off while not logged in. Solution:
log in
•
already authorizing, retry later - authorization in progress. Client already has issued an
authorization request which is not yet complete. Solution: wait for the current request to be
completed, and then try again
•
chap-missing = web browser did not send challenge response (try again, enable
JavaScript) - trying to log in with HTTP-CHAP method using MD5 hash, but HotSpot server does
not know the challenge used for the hash. This may happen if you use BACK buttons in browser; if
JavaScript is not enabled in web browser; if login.html page is not valid; or if challenge value has
expired on server (more than 1h of inactivity). Solution: instructing browser to reload (refresh) the
login page usually helps if JavaScript is enabled and login.html page is valid
•
invalid username ($(username)): this MAC address is not yours - trying to log in using a
MAC address username different from the actual user's MAC address. Solution: no - users with
usernames that look like a MAC address (eg., 12:34:56:78:9a:bc) may only log in from the MAC
address specified as their user name
• session limit reached ($(error-orig)) - depending on licence number of active hotspot clients is
limited to some number. The error is displayed when this limit is reached. Solution: try to log in
later when there will be less concurrent user sessions, or buy an another license that allows more
simultaneous sessions
•
hotspot service is shutting down - RouterOS is currently being restarted or shut down.
Solution: wait until the service will be available again
General fatal errors:
•
internal error ($(error-orig)) - this should never happen. If it will, error page will be shown
displaying this error message (error-orig will describe what has happened). Solution: correct the
error reported
• configuration error ($(error-orig)) - the HotSpot server is not configured properly (error-orig
will describe what has happened). Solution: correct the error reported
•
cannot assign ip address - no more free addresses from pool - unable to get an IP address
from an IP pool as there is no more free IP addresses in that pool. Solution: make sure there is a
sufficient amount of free IP addresses in IP pool
Local HotSpot user database non-fatal errors:
•
invalid username or password - self-explanatory
•
user $(username) is not allowed to log in from this MAC address - trying to log in from a MAC
address different from specified in user database. Solution: log in from the correct MAC address or
take out the limitation
• user $(username) has reached uptime limit - self-explanatory
•
user $(username) has reached traffic limit - either limit-bytes-in or limit-bytes-out limit is reached
•
no more sessions are allowed for user $(username) - the shared-users limit for the user's profile is
reached. Solution: wait until someone with this username logs out, use different login name or extend
the shared-users limit
