fellow geeks,
has anyone else noticed a significant increase in random packages on port 1433? we had a flat out DOS attack on the SQL server port trough all of last week, i finally had to change the standard port for SQL to get it running again. the packages still hit the router/firewall, but now they're just dropped. and they seem to come from everywhere, not just a single source. it slowed down our server(s) to a crawl ...

QUOTE(airsix @ Feb 3 2004, 02:57 PM) The webserver should query the sql daemon via the localhost (127.0.0.1), not over the public interface (unless they are not both are running on the same box of course). i know and i do (for the web-server) but i'm also a lazy-ass and use the enterprise manager to remotely log in into my SQL7 server. therefore, i need a open port ... (IMG:style_emoticons/default/wink.gif) i changed the default port to something else and now it's fine. whatever tool/bug/virus was hitting us seems to be hardcoded to the default port ... Andy |
