To: questions@freebsd.org Date: Sat, 18 May 1996 15:10:36 -0700 (PDT) X-Mailer: ELM [version 2.4 PL24 ME8b] MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Sender: owner-questions@freebsd.org X-Loop: FreeBSD.org Precedence: bulk I have a strange problem that is happening w/ FreeBSD & pppd. I am connecting to my employer (which is also an ISP and which assigns dynamic IP addresses) using pppd and FreeBSD 2.1.0-R. I connect using: pppd connect 'chat "" ATDT####### CONNECT "" user: word: ' /dev/modem 38400 noipdefault crtscts modem defaultroute I get connected and everything works fine EXCEPT if I try to connect to another FreeBSD machine on our network. I've tried connecting to three FreeBSD machines -- if I telnet to those machines, it connects and hangs. If I telnet to those machines on port 80, it hangs. I can't ftp or rlogin to those machines, either. Ping/ traceroute show no weirdness that I can determine. If I telnet to ports on those machines which are running custom written servers that I've (or others) have written including a MUD and a chat server, it seems approx. 800 bytes or so of data is sent and then the connection freezes. HOWEVER, I can telnet/etc. to any other machine that I've tried. AND, I can make successful connections to ftp.freebsd.org/freefall.freebsd.org, etc. Any hints/suggestions? I'm not a strong networking guy so the answer may be very obvious to those who know much more than myself. FWIW, I've used pppd before w/ other UNIX OS's in a similar paradigm w/o a problem, this is why I'm so boggled! Thank you very much, Rich.
