On the other hand, a reverse DNS lookup doesn't work - perhaps this is my entire problem? I'm not sure how to fix it if so! Here's some output: aleph# ifconfig rl0 rl0: flags=8843 mtu 1500 inet6 fe80::2e0:4cff:fe98:36fa%rl0 prefixlen 64 scopeid 0x1 inet 192.168.0.197 netmask 0xffffff00 broadcast 192.168.0.255 ether 00:e0:4c:98:36:fa media: Ethernet autoselect (100baseTX ) status: active aleph# nslookup 192.168.0.197 Server: ns1.dc.cox.net Address: 68.100.16.30 *** ns1.dc.cox.net can't find 192.168.0.197: Non-existent host/domain aleph# cat /etc/resolv.conf search dc.dc.cox.net nameserver 68.100.16.30 nameserver 68.100.16.25 I do have an entry in my /etc/hosts file: 192.168.0.197 aleph.cox.net aleph But apparently it's not reading that. [the change to cox.net is just 5 minutes old, BTW]. Thanks again for the help!
