>Number: 910 >Category: bin >Synopsis: Connection times out >Confidential: no >Severity: serious >Priority: medium >Responsible: freebsd-bugs >State: open >Class: sw-bug >Submitter-Id: current-users >Arrival-Date: Fri Dec 22 22:20:01 PST 1995 >Last-Modified: >Originator: Mikhail Teterin >Organization: >Release: FreeBSD 2.1-STABLE i386 >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. mi@ALDAN.star89.galstar.com >Fix: >Audit-Trail: >Unformatted:
