I have been following this thread for awhile, no let me throw some fuel on the fire! I've had some problems over the past several weeks with what appeared to be some routing problems, but I now believe they are related to the T/TCP (more specificly RFC 1644) implementation in FreeBSD 2.1R. To help illustrate my problem here is a simple network diagram. A B +-------+--------+ | (Ethernet) (FW) | +--+-------C | | | | (PPP) | +-------D | | +-------E Where: Machine C, D and E are FreeBSD 2.1R. Machine A is SunOS. Machine B is Solaris 2.5. Machine A, B, C and D are all within the same domain behind a firewall. Machine E is outside on the Internet. Here is the problem. >From machine D I could ping and traceroute to machine C and E. I could not use and other services (e.g. ftp, rlogin, telnet, http, etc). I would have to go through and intermediate machine (e.g. A or B) to get to C. When ever I tried to access one of these machines (C or E) from D the connection appeared to startup up and then hang. Netstat showed that the connection had been made but output at the terminal never completed (i.e. I never saw the login prompt). For a while I thought I had a routing problem, but when I boot machine D using Windows I could get to machine C and E with no problems. When I first read this thread I felt the problem might be remotely related. When I disabled RFC 1644 support on machine C and D I was able to get into both C and E from D without any problems. Forgive me if this sounds like a silly question, but did anybody test T/TCP between two FreeBSD 2.1R machines? Greg Shaffer
