It’s likely something broken in AT&T’s implementation - I have a G5 (10.5.8) with Comcast and native dual stack which works just fine.

However it did respond to Ctl-C and would then do a “ps -a” no problem, just no “ps -aux”. We were a bit silly, didn’t read our Uverse email, and didn’t test other systems before hooking more old systems into the network - which then didn’t work. We were panicing about viruses, pulling hair out, sacrificing goats ...
