33.3.17 +iSDM — Service Disabling Mode<br />
Syntax: <strong>AT+i</strong>SDM=n<br />
Parameters: n=0 .. 7<br />
Command Options:<br />
Sets the service disabling mode bits.<br />
n= Bitmapped flags:<br />
Nonvolatile Parameter Database<br />
Bit 0: Disable iChip‘s response to ICMP ECHO (PING)<br />
requests. When this bit is set, iChip will not respond to any<br />
PING requests, thereby eliminating the possibility of a PING<br />
attack on iChip.<br />
Bit 1: Disable iChip‘s remote debug daemon. When this bit<br />
is set, iChip will not enable its internal (UDP) debug port,<br />
which is normally activated for administering remote<br />
support.<br />
Bit 3: Disable unauthenticated viewing of the iChip‘s<br />
internal website. When this bit is set, the internal Web site<br />
may be browsed only if the remote browser provides the<br />
RPG parameter (password). In this case, when the RPG<br />
parameter contains a password value, iChip‘s Configuration<br />
Web site will first display a password entry form. The remote<br />
end must submit the correct RPG value in order to continue<br />
to the Configuration site‘s home page. iChip uses the SHA1<br />
hash algorithm throughout the authentication process, so<br />
actual password values are never transmitted. When this bit<br />
is set, but the RPG parameter is empty, the Configuration<br />
Web site is effectively disabled, as all password values will<br />
be rejected. However, if the RPG parameter contains the<br />
special ‗*‘ wildcard value, authentication is bypassed and the<br />
authentication form will be skipped altogether. In this case,<br />
the Configuration website‘s home page will be displayed<br />
immediately.<br />
Default: 0 (All services enabled)<br />
Result Code:<br />
I/OK If n is within limits<br />
I/ERROR Otherwise<br />
<strong>AT+i</strong>SDM? Returns current Service Disabling mode followed by I/OK.<br />
<strong>AT+i</strong>SDM=? Returns the message ―0-7‖ followed by I/OK.
