What you're doing is telling FreeBSD: * I have an interface called 193.78.175.2, and through it you can talk to 193.78.175.* (via the netmask 0xffffff00). * I also have an interface called 193.78.175.3, and through it you can talk to 193.78.175.* (via the netmask 0xffffff00). Hence the "File already exists" message. You cannot have two physically different wires that have the same network (193.78.175.*) on them. This is a TCP/IP issue, not a FreeBSD problem. You should either subnet your network into two portions via the netmasks (e.g. the first wire gets 193.78.175.x for x >= 128, and the second one gets 193.78.175.x for x <= 127), or get a second network. -- Denis Fortin fortin@acm.org DMR Group Inc, (514) 877-3301 These opinions are my own
