>Environment:
The machine I'm trying to connect to is connected to the
Internet thru one ppp-link (pppd is used).
One of the "from"-machines tried was connected thru user's ppp.
Another one -- ethernetted machine with a constant IP-address
Both "from" machines run 2.1-Release
>Description:
Direct connection on telnet, ftp and X ports times out (did
not test other ones). To connect from work, I have to first
login to the Sun machine on the same net (the Sun is not
any different from the net point of view -- it is not a
server of any kind, and stands behind the same firewall on
the same net (first three bytes of IP number, and netmask
are same). Connection from the Sun goes right a way...
Here is a little picture of how it looks on the "to"-machine
(with my comments):
mi@aldan:~ (33) ps -axl | grep telnet
0 28843 81 0 2 0 192 496 netio I ?? 0:00.08 telnetd
0 28849 81 0 2 0 232 528 select S ?? 0:00.47 telnetd
mi@aldan:~ (34) netstat -a | grep telnet
tcp 0 4 PPP-72-5.BU.EDU.telnet 128.191.56.82.32797 ESTABLISHED
tcp 0 15 PPP-72-5.BU.EDU.telnet kot.1117 ESTABLISHED
tcp 0 0 *.telnet_b *.* LISTEN
tcp 0 0 *.telnet *.* LISTEN
The first process is the "forever-waiting" telnetd (telnet-client
on the "from machine" says "Connected to ..." and never gives a
login-prompt). The second process is working telnetd, which made
the whole picture possible. The second telnetd works with the Sun's
telnet client.
PPP-72-5.BU.EDU is the temporary name of the "to"-machine (perfectly
functional otherwise).
>How-To-Repeat:
Try to connect (on telnet, ftp, or X port) to the FreeBSD machine,
with dynamicly assigned IP-address from another FreeBSD machine.
Note, that both "from"-machines running Windows NT can perfectly
connect to the same FreeBSD running "to"...
E-mail me for the current name/ip-address of my machine to try.
