Interesting you mention that. I've transferred stuff over ftp/http/ssh up/down with no problem. On the other hand, as you point out, bind9 uses udp for queries initially, and openswan uses udp as well. I went ahead and contacted my VPS provider's support, since there doesn't seem to be much more I can do here on my own. So, we'll see what finally fixes things. I'll post back here when that happens to close this out. One more thing I forgot to mention here is that back when bind9 was causing the machine to crash at boot, I brought down the eth0 interface, and was able to stop/start bind9 as much as I wanted without problems. So, it could very well be something with the virtio_net module. Will be interesting to see what solves this. > > BTW... What do you have in /etc/nsswitch.conf?

Yes, when I run grep like you show above, I get back exactly what you did. It has other lines in there, so the whole file doesn't just say hosts: files dns all by itself. So, I assume you're asking if that one line just says hosts: files dns, not that the entire file consists of that, and only that. If that is the intended question, the answer is yes. Thanks again for your help Bob.
