Package: ser2net
Version: 2.9.1-1
Severity: normal
Dear Maintainer,
current stable (jessie) version is probably build without --with-tcp-wrappers
option enabled.
* What led up to the situation?
/etc/hosts.(allow|deny) is ignored for ser2net
* What exactly did you do (or not do) that was effective (or
ineffective)?
put "ser2net: ALL" in /etc/hosts.deny
* What was the outcome of this action?
connection were established and serial port were accessible
* What outcome did you expect instead?
Error message saying access denied as it should based on manpage ser2net(8)
section SECURITY
* additional info
