check_certexp is a Nagios plugin for checking the number of days left until a
certificate expires. The check is done via an SSL connection (STARTTLS
mechanisms are not supported). The plugin is written in Perl, should work with
the embedded Perl interpreter (not tested though) and requires Net::SSLeay and
Date::Manip to be installed on the Nagios host.

Newsx is an NNTP client for Unix. It will connect to a remote NNTP
server and post outgoing articles batched by the news system, as well as
fetch incoming articles.
It provides the NNTP capabilities required for small local news spools
on installations with NNTP access only through limited ISP accounts. It
works well via a dialup SLIP/PPP connection.
Newsx is also well suited for large spools with normal feeds, being
used for pulling newsgroups from specific NNTP servers that are not
distributed in the usual manner. Since newsx obeys the normal news spool
configuration file and requires little or no specific configuration, the
administrative burden should be minimized.

HAProxy is a free, very fast and reliable solution offering high
availability, load balancing, and proxying for TCP and HTTP-based
