>Description:
exim built with libwrap and following stanzas in /etc/hosts.allow:
exim : localhost : allow
ALL : ALL \
: severity auth.info \
: twist /bin/echo "You aren't welcome to use %d from %h."
does not give expected behaviour when trying to contact exim from a remote machine. Expect (with telnet hydra 25):
You aren't welcome to use exim from sphinx.
but get nothing.
Get in /var/log/messages:
Mar 25 17:45:52 hydra exim: warning: /etc/hosts.allow, line 77: twist_option: dup: Bad file descriptor
and in /var/log/auth.log:
Mar 25 17:45:52 hydra exim: twist sphinx to /bin/echo "You aren't welcome to use exim from sphinx."
Seems to be associated with exim only. If I replace exim with sshd in /etc/hosts.allow then works as expected.
>How-To-Repeat:
1. Build mail/exim with tcpwrappers enabled.
2. In /etc/hosts.allow:
Remove default match anything rule
Add:
exim : localhost : allow
as only matching rule for exim.
3. telnet machine 25
