Dear Ladies and Gentlmen, I am writing to ask your help with this message Connected to blah. Escape character is '^]'. telnetd: All network ports in use. Connection closed by foreign host. This occurred after generating and booting a custom 4.1-RELEASE kernel, and with changes to /etc/rc.conf like sendmail_enable="NO". These observations may be relevant. The problem machine is . not accepting *any* telnet connections (but is accepting ftp connections), so the ptys can't be exhausted by other sessions. . has not had ptys added or deleted in /dev . has not, to the best of my knowledge, had the pty pseuod-device entry in the kernel configuration file changed from as it appears in GENERIC. It remains as it is in /usr/src/sys/i386/conf/GENERIC ie pseudo-device pty # Pseudo-ttys (telnet etc) Why isn't there a number after pty ? It's possible, however, that I commmented it out mistakenly when trying to do so for the tun or md pseudo-devices. My reasons for asking include 1 There is nothing in the FAQ about this 2 Frequent advice in "Questions" to rebuild the kernel with more ptys. If I haven't touched ptys, and perhaps others are the same, then this advice is useless. 3 This is the second time this has happened to me with a 4.x kernel (never in 3.x or 2.1.x and 2.2.x). I don't think anything's wrong with the 4.x kernel but this may be a common mistake that others can avoid. Thank you, Yours sincerely.
