Open Source Lazarus Networking Software

We are developing a set of Delphi components to communicate with a ModBus PLC over TCP/IP. The library provides components to implement both a ModBus master and a Modbus slave, and is based on the Indy component set (both Indy 9 and 10 are supported) De source code of the project has been moved to GitHub!

P.SEN is a utility to allow sending and receiving TCP and UDP packets and is available for Windows and Linux. It's designed to be very easy to use while still providing enough features for power users to do what they need. It is completely free (no ads / no bundleware) and opensource. Some knowledge of a basic network protocols is a prerequisite to using it. Beyond that, P.SEN was designed to be very easy to use.

WandS (Wake and Shutdown) is an program for webmaster or sysadmins that want take control over your servers at datacenter. With WandS, you can shutdown or awakening any servers or servers group in any time through protocol SSH or SMB

The purpose of this program is to monitor the state of an ADSL or VDSL2 connection. It works with DSL routers using Broadcom chipsets, which have a fully functional telnet interface with access to the Broadcom CLI. It also supports some Thomson/Technicolor routers via their custom CLI, but some of the features of the program are not available for these models. All of the data is obtained from the CLI via telnet. Data is displayed in graphical form, and also can be seen in raw telnet CLI format.

COM Serial Terminal Update: Support COM Trigger Transmitting Win32/64 Ver

Major Pinger is a pinger that returns most ping related information and generated statistics. It not only can be used to ping a site's availability, but can also be used to ping a downed site to determine when it is available. Report listing can be by Error, Ping OK, or All information. Information is written to the window at the bottom of the interface and to a log file. Alarms can be set to sound upon site ping OK or after a number of ping errors overall or after a number of sequential ping errors. Major Pinger can now ping a port (= open/close a port) to determine if a port is currently available.

Handle every connection on different windows really simple, like chatting! Whit this too you can start a server, what listens on a specific port and/or connect to a specific host name with a specific port. The incomming/outgoing connections are appearing in popup windows. Written in Lazarus

Easy tcp network tools Can working as TCP server and / or client together

MyMonitor is a graphical application that performs pings and creates a log file, which contains the result of failed pings. New version added integration with umap

Just test if same UDP/TCP ports are open, usefull to test firewalls/portforwards
