travelmate: update 1.4.10
* add missing dnsmasq dependency * add a captive portal auto-login hook (configurable via uci/LuCI), you could reference an external auto-login script - see readme * provide an auto-login script for german ICE hotspots (/etc/travelmate/wifionice.login), requires 'curl' * small fixes Signed-off-by: Dirk Brenken <dev@brenken.org>

## Captive Portal auto-logins
|
||||
For automated captive portal logins you could reference external shell scripts. All login scripts should be executable and located in '/etc/travelmate' with the extension '.login'. The provided 'wifionice.login' script example requires curl and automates the login to german ICE hotspots, it also explains the principle approach to extract runtime data like security tokens for a succesful login. Hopefully more scripts for different captive portals will be provided by the community ...
|
||||
|
||||
A typical/succesful captive portal login looks like this:
