wodTelnetDLX is a telnet client component ready to connect to various terminal based clients, most commonly to UNIX telnet daemon. Besides supported Telnet protocol, it also supports secured communication (through encryption) using well known SSH (SSH1 and SSH2 are supported), as well as SSL/TLS (Secure Socket Layer protocol).
ActiveX version of the component has its own Terminal GUI (Graphic user interface) that supports VT100 emulation - so you can run your favorite UNIX tools with no need for 3rd party extensions - only with wodTelnetDLX.
Very similar to our wodSSH component - wodTelnetDLX brings you client implementation for most important telnet-based clients used today - with same interface for all of them. With one small change in your code (Protocol property), you can switch to secured protocol from just by reconnecting! Everything else is the same - interface, behavior, events ...
Using wodTelnetDLX is really easy - set Hostname and Protocol (Telnet is set as default), and issue Connect method. Once connected, wodTelnetDLX will fire Connected event and you can start sending and receiving data. Each time data is received by the component, Received event is fired where you can read data and print it to screen, store it, evaluate, issue new commands etc.
Secured communication is implemented using SSH protocols (both SSH1 and SSH2) and SSL/TLS implementation. You can use enclosed 'Certificate Management' component to select certificate/private key to connect to server without need to remember any passwords - if your server supports this. It supports both RSA and DSA private keys, as well as installed certificates that hold these keys, through Certificate property.
When working in Blocking mode (COM version only), wodTelnetDLX will block its execution until issued command is fully performed. For example, if you call Receive method and there is no data available, it will hold execution until data is received from the server, or throw Timeout error after timeout value expires - where you can send new commands..
You can specify expected prompt string sent by the client. If set, wodTelnetDLX will fire PromptReceived event will be fired each time prompt is received - a perfect place to send new commands to the server.
Using RAW mode, you can connect to various character-based servers, such as POP3 or SMTP. They are encrypted? POP3/S or SMTP/S? No problem - switch to SSL mode and do everything the same as before. You will see no change, let wodTelnetDLX handle encryption internally.
wodTelnetDLX is tested to work properly in VB, VC and ASP, and as our other components integrates to Delphi very nicely. Make sure you check it out...
