Further point to consider: afsc-bmo is at 131.62.7.1... ^^^ > From my vantage point on DDN, I get a network unreachable. > Chances are an AF Concentrator has recently been installed or has failed. > Whoa! The concentrator must not have as good a rep as I thought. As it happens, the concentrator has been at Norton for quite a while, and yesterday the cisco gateway's line to the PSN had hung up - probably why you got the net unreachable. Last night, it hung again at around 1130, so today (this morning) it had been flushed from the Core Gateways' tables, and again should have been showing net unreachable. We couldn't get ahold of anyone at the site to check it during the odd hours. It is now up. We have had an outstanding problem with ciscos using the MCI card hanging on the line to the Milnet Node. We have also had a problem with the Milnet monitors just deciding to loop back ports that concentrators are connected to without contacting us. Oh, and if you look it up, the NIC still has the concentrator registered as NORTON-PIV-I, which is the name of a Unisys mainframe that has been rehomed behind the concentrator. You can contact us for further questions, but things seems to be back to normal. /matt -- Lt Matthew W Jonson jonson@server.af.mil snail-mail: Network Systems Engineer 205-279-4075 SSC/SSMT USAF DDN Program Office AV: 596-4075 Gunter AFB, AL 36114
