In the latest firmware of RUT955 (RUT9_R_00.07.03.4), I think that there is a bug on Web GUI.
On "SMS forwarding to HTTP" configuration, whatever special and valid character you type in URL field, you get an error.
Some examples, that are valid, but not accepted:
192.168.1.100/awp/getsms (the second slash is not accepted)
192.168.1.100/getsms.php (the dot is not accepted)
Although, if I edit using ssh and vim the file /etc/config/sms_gateway, I can add those valid (but not accepted) urls, and I can see them on the Web GUI.
Another problem, is that whenever the RUT955 tries to do an HTTP Get request (after receiving an SMS), then it adds an extra ampersand right after the question mark.
For example, if the URL is configured to be 192.168.1.100/getsms, then the curl command is trying to access the url http://192.168.1.100/getsms?&txtmsg=TestMessage (verified by logread -f)
I hope you can see the extra unneeded ampersand. This ampersand (right after the question mark), gives an error on some old and basic web servers.
Is there anything I can do (using ssh maybe), to fix that error?
Thanks.
