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
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
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:
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
I am open to suggestions.
