A workaround will be in place by 18:00 CST until the machine can be replaced or repaired. A gross hack is currently providing connectivity to my services network, where {ftp,mail}.freebsd.sol.net live, but any other services may be temporarily interrupted until this problem is corrected. The problem is compounded by the fact that I am not able to get down to the office until after 17:00 CST. My apologies. This brings up a side issue. I have been talking for months about building in more redundancy to my networking infrastructure. With Ethernet stuff being dirt cheap, there is no reason for this kind of thing... I am seriously intending to start running redundant Ethernets and stuff to all key systems. I believe that if I start using OSPF internally, this should be practical and possible, but I am no GateD whiz, and I don't know how to go about this. I did buy "Routing in the Internet" but haven't made a serious dent in trying to understand the OSPF routing stuff yet. (Issues never come up at convenient times). What I would like to do, best case, is something like this... Net 206.55.64.0/28 Net 206.55.64.16/28 ---------- ---------- ---------- b |---| Router | ------------| Box 1 |------------ | Router |---| b b | ---------- / ---------- \ ---------- | b 1 | / \ | 2 | ----------/ ---------- \---------- | |---| Router |---------------| Box 2 |---------------| Router |---| | ---------- ---------- ---------- | Obviously not a complete net view... Right now, "Box 1" and "Box 2" are connected to a common ethernet which is in turn connected to my core router, which connects via my backbone Ethernet to a border router. What I would like to do is to set up a second core router... the obvious way is to simply connect it to the current "common ethernet" for Box 1 and Box 2. However, that does not protect against a failed hub or a bad wire. Running a separate wire from each core router to the box seems absurd at first until you realize it can be done with no hubs, and good hubs being rather pricey, this starts to look attractive. Any comments from OSPF gurus? ... JG
