Adding more then 255 IPs to an interface in Solaris

By default, solaris will only let you add 255 IP addresses to an interface. You’ll know you hit the limit when you get an out of buffer message when you try to add your next one. In Solaris 2.5, you’re pretty much stuck with this limitation. In solaris 2.6 and higher, you can run the followng to up that limit as high as 8192. Past 8192, you’ll need to add another interface.

/usr/sbin/ndd -set /dev/ip ip_addrs_per_if 8192

Decoding gzinflate base64_decode files using php

Another little gem I found on the web. I’ve come across a few files that show up as base64_decode files when you look at them, but after php has had it’s way, they output text. Come to find out, it’s a not so clever way to obfuscate code. Other folks have had need to view these files too and have posted handy little tools to aid in that effort. Here’s one of them. Just create files called decode.php, decoded.txt and coded.txt . Put the obfuscated code in coded.txt, put this program code into decode.php and run it. The output will show up in decoded.txt . Note that this is a PHP program and requires PHP to run.

echo “\nDECODE nested eval(gzinflate()) by DEBO Jurgen \n\n”;
echo “1. Reading coded.txt\n”;
$fp1 = fopen (“coded.txt”, “r”);
$contents = fread ($fp1, filesize (“coded.txt”));
fclose($fp1);
echo “2. Decoding\n”;
while (preg_match(“/eval\(gzinflate/”,$contents)) {
$contents=preg_replace(“/<\?|\?>/”, “”, $contents); eval(preg_replace(“/eval/”, “\$contents=”, $contents)); } echo “3. Writing decoded.txt\n”; $fp2 = fopen(“decoded.txt”,”w”); fwrite($fp2, trim($contents)); fclose($fp2);
?>
