Yes, netcomponents comes as a free download - try ORO Software Archive - Savarese.Org. It works very well for doing both remote execution and FTP.
The executer adapter is available from wM free of charge (at least it was when I last checked). However, if I remember correctly, they don’t really support the executer adapter anymore.
Are you doing this from ES or IS? If from IS, also have a look at WmSamples package under commandLineExec (don’t know if it’ll work on Unix, haven’t tried that yet).
