Thanks for the reply. I was about to purge network manager on my own based on posts I've seen. Have use both DHCP and static with MN installed on earlier versions with no issues. I'm using static as NoOP convinced me that was better but I can be unconvinced if I will fix my sharing issue as I have needs to copy files between PCs. If you have more to add please do. BTW, attyahoo dsl has always provided the same IPs on this side of the router since day one.

Yes, AFAIK. I'm not very network literate, mostly illiterate-:)) But my config is as you list above. Y's are 3 and 2 and subnet mask is as you listed.

Oh boy, I have been trying but don't know what to do. Thanks for the info about exports as I don't know anything about NFS and don't think I was using it before as I never did a setup on it. I've never had an issue pinging between machins before so don't really know what to troubleshoot.

I have windows vista on the new machine and keep it up to date occasionally but have no desire to share files on it. I just want the minimal required, simplest setup that allows me to use nautilus/dolphin in kde to copy/move files between machines. And unless NoOP, who helped me get file sharing working for the first time told me how, I never used it before. Sorry, I don't remember about NFS for sure but everything I came across googling was unfamiliar. I got where I am now by following the hits and I know I haven't tried to mount anything yet as the howto was confusing saying I had to mount a new empty dir instead of my home or tempdid set up to share. Hope the info I provided gives you a clue why I can't ping the other machines. If purging network manager doesn't fix it, I'm still lost. Thanks for the input.
