isns01@ms3.UUCP (Jim Chappell) (07/19/87)
We are running vanilla 4.2BSD on Vaxen 11/780s. We use DEC DR-11 Direct Memory Access hardware connected to an Ungermann-Bass NIU-150 to implement TCP/IP over a broadband LAN. One of our Vaxen (hostname 'tlog') has a ACC DH/LH + modem connected to PSN 76 to implement milnet access. A representative interior VAX is 'ms3'. Visually, we have: --------- --------- | ms3 | | tlog | | | | |---\/\/---PSN 76--------| milnet | ---|----- ---|---- | | ------ ------- |NIU | | NIU | --|---- ---|--- --|--------------------------------|--------------------- --------------------------------------------------------- My problem exists on hosts interior to 'tlog' I have been unable to access the milnet directly from such hosts. Can anyone help me out? Also, what's the best documentation to use to get a handle on this beast? The ifconfig we use on ms3 is: /etc/ifconfig ub0 -trailers arp 92.0.0.6 Here's a script(1) output of what I've tried: Script started on Sat Jul 18 19:39:08 1987 ROOT(ms3) 1: netstat -r Routing tables Destination Gateway Flags Refcnt Use Interface loopback 127.0.0.1 U 0 0 lo0 92.0.0 ms3 U 0 7269 ub0 ROOT(ms3) 2: route add default tlog 0 add 0.0.0: gateway tlog, flags 1 ROOT(ms3) 3: netstat -r Routing tables Destination Gateway Flags Refcnt Use Interface default tlog U 0 0 ub0 loopback 127.0.0.1 U 0 0 lo0 92.0.0 ms3 U 0 7270 ub0 ROOT(ms3) 4: whosis Chappell whois: connect: Connection timed out ROOT(ms3) 5: netstat -r Routing tables Destination Gateway Flags Refcnt Use Interface default tlog U 0 11 ub0 loopback 127.0.0.1 U 0 0 lo0 92.0.0 ms3 U 0 7273 ub0 ROOT(ms3) 6: ^D script done on Sat Jul 18 19:41:08 1987 Script started on Sat Jul 18 20:07:29 1987 ROOT(ms3) 1: route add sri-nic tlog 1 add sri-nic: gateway tlog, flags 7 ROOT(ms3) 2: netstat -r Routing tables Destination Gateway Flags Refcnt Use Interface sri-nic tlog UGH 0 0 ub0 default tlog U 0 11 ub0 loopback 127.0.0.1 U 0 0 lo0 92.0.0 ms3 U 0 7387 ub0 ROOT(ms3) 3: whois Chappell whois: connect: Connection timed out ROOT(ms3) 4: netstat -r Routing tables Destination Gateway Flags Refcnt Use Interface sri-nic tlog UGH 0 11 ub0 default tlog U 0 11 ub0 loopback 127.0.0.1 U 0 0 lo0 92.0.0 ms3 U 0 7390 ub0 ROOT(ms3) 5: ^D script done on Sat Jul 18 20:09:00 1987 -- Jim Chappell ...!seismo!vrdxhq!ms3!jrc ISN Corp.

I have been unable to access the milnet directly from such hosts.
/etc/ifconfig ub0 -trailers arp 92.0.0.6
Jim,
Ask yourself the following question:
How will other hosts on the MILNET, and other gateways farther away, know how
to reach net 92?
You should go to your provider of operating system software, which you said is
4.2BSD unix, and ask them about configuring the gateway software for this
setup. The key to answering the question I posed above is the program which
handles the "Exterior Gateway Protocol" (EGP), which should be provided as
part of your network software.
Also, you need to address the NIC to get a registered network number for your
Ungermann-Bass net, as well as an Autonomous System number (related to the
EGP). Send your inquiry to 'hostmaster@sri-nic.arpa'.
