I'm trying to use curl to log in to a router so I can retrieve the
current WAN IP address periodically - it changes at least twice a week
and getting it manually is annoying (obviously I need to do this from
the LAN side). I can get the appropriate line through curl and grep once
I'm logged in, but I'm not sure how to do the submit. The examples I've
seen use the name of the submit button to post the form data, but the
button on my router doesn't have a name. The relevant HTML code is
<BODY bgcolor="#0000FF">
<form action="login.htm" method="post" name="tF">
<input type="hidden" name="page" value="login">
<table border="0" width="100%" height="184" cellspacing="0">
<tr>
<td width="50%" height="19" align="right">
<font face="Arial, Helvetica, sans-serif" size="2"
color="#FFFFFF">Password :</font></td>
<td width="50%" height="19" align="left">
<INPUT type="password" maxLength=12 size=9 name=pws></td><p>
</tr>
<tr>
<td width="50%" height="19" align="right">
<INPUT type="submit" value="Login"><img src="image/PIXEL.GIF"
width="6" height="1">
</td>
<td width="50%" height="19" align="left">
<INPUT class=button onclick=window.close(); type=button value=Cancel>
</td>
</tr>
</table>
</body>
</FORM>
</BODY>
I'm not sure if the mistake in the HTML coding (incorrect closure of the
</body> and </form> tags is important, but the login form does work if I
log in through a browser. I just need to do it through curl!
So if anyone can tell me how to use curl to do a submit without a named
submit button, I'd appreciate it. :)
