Gah! Computer security is annoying!
Due to some recent attacks [1], we've implemented some ad-hoc changes to network security until we can get something better into place. Right now, we're filtering all ssh [2] traffic on our routers, as well as on some individual servers, in addition to single packet authentication [3] on one of our servers.
And I don't know what's more annoying—the script kiddies or our ad-hoc security measures.
I wasted today just trying to get this “single packet authentication” thingy working (since I need to work on “Project: Leaflet [4]” and it would make my life a whole lot easier if I could log in directly) only to have it fail.
Miserably. (How miserably? I turned off the filtering on the router, the firewall on the physical server, the actual single packet authentication daemon, allowed anyone to log in via ssh, and I still wasn't getting through. Aaaaaaaaaaaaaaaaaaaaaaahhhhhhh!)
