Please let me know if more info is needed.
My box is pingable from other (remote) systems fine, also is pingable on the local network. I can ping it and ssh into it, etc. but not from itself.
I did try searching google and the debian-list-archives but didn't see much on this.
I did find that the errors to ld.so.nohwcap and ld.so.preload are meaningless.
Any help appreciated! Thanks.
