FreeBSD 11.4-RELEASE-p4 OpenSSL 1.1.1h 22 SEPT 2020 I recently had to do a fresh installation of FreeBSD on a new HD, do to the fact that the old HD died. I cannot install anything newer than 11.x due to a bug <https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=237666>. After the new installation, I attempted to check Postfix and Dovecot via 'telnet' and OpenSSL. Now when I attempt to use telnet to access either one from a machine on the network, I receive an error message: telnet domain.net 25 Trying XXX.XXX.XXX.XXX... telnet: connect to address XXX.XXX.XXX.XXX: Connection refused telnet: Unable to connect to remote host Now, if I use the full computer name, everything works as expected. The same problem happens with OpenSSL openssl s_client -connect domain.net:587 -starttls smtp 34387091456:error:0200203D:system library:connect:Connection refused:crypto/bio/b_sock2.c:110: 34387091456:error:2008A067:BIO routines:BIO_connect:connect error:crypto/bio/b_sock2.c:111: connect:errno=61 If I use the full computer name, it works. If I try either command from a PC not connected to the same network, using either name, everything works as expected. I didn't have this problem before I did the reinstall. I don't think it is a firewall problem because I have tried with the firewall disconnected. This is not the behavior I experienced before this reinstall. I figure I am doing something dumb, but I cannot figure out what, and I don't have a lot of time to play around with it; I am getting really busy at work now. I am open to suggestions. -- Jerry
