Glad to hear. I would, however, still like to know the *details* of your setup so I can *reproduce* the problem. Without proper configuration details, all I - or anyone - can do is guess. The information you provided so far is not very helpful in this regard. > I maintain that this issue would need to look into, anyway... Yes ... but unless the issue can be reproduced in a controlled environment, it's next to impossible to do so. > I don't think that a system freezing is acceptable, even when the > administrator > makes some configuration mistakes: the o.s. should complain about > "routing or ethernet loop", without leaving him wondering... I'm afraid in this regard we (or any other o.s. for that matter) are just rope vendors. Network configuration is complicated business. The more components you throw in the mix, the easier it gets to hang yourself in the ensuing web. Sorry I can't be of more help, but again: without details about your setup, everything is just guesswork! Max
