NTP compromise?
 

I've been having some odd problems lately that I thought were related to networking. Essentially my access to the internet was freezing from time to time. I finally noticed that it was more or less on the few minutes before and after the half hour and that got me to wondering about ntp. I opened up the gnome time applet and there were a lot more ntp servers checked than I ever remember setting. I've cleared out all but 3 and the thing seems to have settled back into some level of normalcy.

My system: Debian, quad core AMD, wireless with WPA-PSK encryption to AT&T's wireless router. This is lower-middle class suburbia and I know everyone that has a router up that I can see. No holes in the firewall that I know of. This is not a commercial site. Just my access point.

So, have I been compromised through NTP or is this just some sort of meltdown/ NTP-timewar that was closing up my network every half hour?

This sounds interesting what were the names of the servers?:)

cheers

They're gone, but I would swear that some were Debian Timeservers, which seemed strange.
