I've installed a BSD box twice now on an Ethernet segment that contains a few other machines all using ten-net addresses and a mask of 255.255.255.0 The BSD box has full IP access to the network, I can ping, ftp and telnet anywhere from it. But I can not access it from another machine. I was beginning to think that it was a trust relationship thing because I can not reach the BSD box at any IP layer from another box. I tried pinging, telnet, and ftp and the box just does not respond unless I run something like netstat (or route flush) and then it does respond but only while netstat is running on the BSD box. As soon as netstat stops the pings begin to time out again. When I flush the routes I can reach it for a short time but then the machine must rediscover its incorrect routing info and I begin to time out again. Initially I thought that maybe BSD has a problem with classless routing. It seems like a routing problem but I don't know whay or why. I am running routed. Does this make any sense at all? Can someone suggest some trouble shooting steps? -----Original Message----- From: Dan Langille [mailto:junkmale@xtra.co.nz] Sent: Friday, April 16, 1999 5:47 PM To: Rich Webster Cc: questions@FreeBSD.ORG Subject: Re: newbie IP question On 16 Apr 99, at 14:54, Rich Webster wrote: > I have installed a BSD box twice now and it seems to work fine.

Thank you very much in advance. I've been playing > with this for a while and am now pretty frustrated. There a few things you need to do here. 1 - make the FreeBSD box a gateway. 2 - enable ip alaising on the FreeBSD box 3 - make the FreeBSD box your default gateway on your other boxes. To do this you need: see http://www.freebsddiary.com/freebsd/alias.htm I am assuming you are using PPP. If not, then please complain. -- Dan Langille The FreeBSD Diary http://www.FreeBSDDiary.com/freebsd Richard Webster Internetwork Solutions Engineer Total Network Solutions, Inc. 630 Freedom Business Center Suite 314 King of Prussia, PA 19406 Phone: (610) 768-7789 Fax: (610) 768-7776 email: rwebster@tns-inc.com <mailto:rwebster@tns-inc.com> Website: www.tns-inc.com <http://www.tns-inc.com>; To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
