Wifidog gateway was down when this error was put out.<br>

Debug messages for popen() are written in line 458 and 497. Like
this,<br>
<br>
/* Look for outgoing traffic */<br>
safe_asprintf(&script, "%s %s", "iptables", "-v -n -x -t
mangle -L " TABLE_WIFIDOG_OUTGOING);<br>
iptables_insert_gateway_id(&script);<br>
output = popen(script, "r");<br>
free(script);<br>
if (!output) {<br>
debug(LOG_ERR, "popen(): %s", strerror(errno));<br>
return -1;<br>
}<br>
<br>
If "output" is false, iptables_fw_counters_update() function seems
to end without pclese().<br>

<br>
I'm not a skilled programmer, please correct me if I'm wrong.<br>
<br>
Thanks in advance,<br>
