TO: ethernet and internet experts We have been hooked up to the MILNET for years. Just recently a need has been defined to set up an ethernet network with other machines at our installation. We currently run with UNIX 4.3 BSD on a VAX 11/780 using the named server. I need to know what the problems are in hooking up an ethernet network up to our VAX. We have tried attaching the network to a VAX 11/780 running UNIX 4.3 BSD without the named server as a test. The connection was made to the VAX via a DEC DELUA board, so the software seems standard. We ran into a few problems. When we run our ifconfig de0 inet hostname -trailers up netmask 255.255.0.0, the ifconfig lo0 localhost reports a bad value. I can run ifconfig lo0 127.0.0.1 alright but the name localhost cannot be used. Also netstat has lost the ability to use host names, so now it will only work with the -n option. Telnet ftp and mail are fine to other machines on the ethernet network. At this point I need more information before I try hooking the ethernet network to our VAX 11/780 connected to the Internet. The real hookup will involve the named server on the VAX and a Promulgate mail server on our ethernet network to distribute mail to PCs. Any infomation would be appreciated. I suspect that the problems we had were connected with the netmask but I have not had the time to confirm this. Please mail to me directly at jkim@nadc.arpa for we have some tough dead lines.
