Honeyd is a small daemon that creates virtual hosts on a network. The hosts can be configured to run arbitrary services, and their TCP personality can be adapted so that they appear to be running certain versions of operating systems. Honeyd enables a single host to claim multiple addresses - I have tested up to 65536 - on a LAN for network simulation.

The Enhanced TightVNC Viewer package started as a project to add some patches to the long neglected Unix TightVNC Viewer. However, now the front-end GUI and wrapper scripts features dwarf the Unix TightVNC Viewer patches (see the lists below). It adds a GUI for Windows, Mac OS X, and Unix that automatically starts up STUNNEL SSL tunnel for SSL or SSH connections to x11vnc, and then launches the TightVNC Viewer to use the tunnel. It also enables SSL encrypted VNC connections to any other VNC Server running an SSL tunnel, such as STUNNEL, at their end. It can be used to perform SSH tunnelled connections to any VNC Server as well. The tool has many additional features (see below for a list). The short name for this project is "ssvnc" for SSL/SSH VNC Viewer.

Ncat concatenates data streams similar to "cat" except the streams can be files or TCP connections. Ncat makes it easy to pipe data between hosts.

MPICH2 is an implementation of the Message-Passing Interface (MPI). The goals of MPICH2 are to provide an MPI implementation for important platforms, including clusters, SMPs, and massively parallel processors. It also provides a vehicle for MPI implementation research and for developing new and better parallel programming environments

Belle-sip is a SIP (RFC3261) implementation written in C, with an object oriented API. * RFC3261 compliant implementation of SIP parser, writer, transactions and dialog layers * http client api * support of client TLS certificate * fully asynchronous transport layer (UDP, TCP, TLS) * fully asynchronous DNS resolution with SRV * full dual-stack IPv6 support * SIP transaction state machines with lastest corrections (RFC6026) * automatic management of request refreshes with network disconnection resiliency thanks to the "refresher" object * supported platforms: Linux, Mac OSX, Windows XP+, iOS, Android, Blackberry 10

Citrix(R) Presentation Server(TM) runs on Microsoft(R) Windows Server(TM) and UNIX(R) operating systems, and extends the base Windows Terminal Services platform by enhancing the end-user experience as well as increasing manageability, compatibility, security and scalability to address business-critical environments. This port includes the Citrix(R) Receiver(TM) software which allows connecting to Citrix(R) Presentation Server(TM). You will need to create the directory ${LINUXBASE}/dev or risk crashing your system. If your Citrix server does not have one of the supplied root-certificates, you can copy the certificate to /usr/ports/distfiles and add the following line to your /etc/make.conf: ICA_CERTS=mycert.crt It will then automatically be installed and removed with the normal FreeBSD package tools.

The idea is that IPFilter in its current state can already do a simple L4 round-robin in its NAT rules. However, it does not detect or sense when a service and/or host is down. It will continue to send requests to a downed service/host. However, IPFilter lets us add and remove rules on-the-fly so it should be possible to build a daemon that lets you specify "clusters". In each cluster you would specify its members/hosts and services. As well as a health-check for the service to determine its current state. Once a service was deemed "up" we would add a Round-Robin rule to the NAT table, and naturally, the reverse once we detect a service as being "down". In addition to this, this program can optionally add ipf rules to log for RST (reset) packets coming from the members of your clusters. In the situations where the software/port goes down, but the host itself is still working, we would detect failure instantly. (Since the forwarded connections to the service would trigger a RST packet back). If this option is enabled, l4ip spawns the "ipmon" command to monitor for the "log" entries given when such a packet is detected. l4ip will then mark the service down. This is an add-on feature and is strictly not necessary for functional usage. It is currently only supported for TCP.

Perl module to parse traceroute(8).

mod_ldap and mod_quotatab_ldap modules for ProFTPD

The SuSE Proxy-Suite, a set of programs to enhance firewall security. The first (and currently only) component being released is the FTP-Proxy. * Securely relays FTP connections between clients and servers * Can switch connections from active to passive and vice versa * Utilizes port ranges for both control and data connections * Provides extensive auditing (via syslog or rotating log files) * Can separate user related from system triggered audit events * Provides command restriction based on logged in user name * Allows command argument checking with regular expressions * Is able to retrieve configuration data from an LDAP directory * Has been thoroughly tested against buffer overflow attacks * Fully conforms to RFC 959 and 1123 (the basic FTP RFCs) * Planned to support RFC 1579 ("Firewall Friendly FTP") * Planned to support RFC 2428 (IPv6 Extensions for FTP) * Based on GNU AutoConf, supposed to run on many UNIX systems Ported to FreeBSD using OpenBSD port by Camiel Dobbelaar <cd@sentia.nl>, with updates contributed by Marius Tomaschewski <mat@mt-home.net>.
