note BrowserUk <blockquote><i>There are as many threads running as there are machines and commands</i></blockquote> <p>Only if you run the different commands for each machine from different threads. That's the wrong way to do it. <p>If you look at the code snippets I posted, one thread connect to one machine, opens one file, and <i>runs all the commands for that machine</i>, <b>sequentially</b>. That way, there is no possibility for ordering problems or file conflicts. <blockquote><i>Maybe I am missing something?</i></blockquote> <p>Please read my last post slowly and thoroughly. Making multiple connections to each machine from different threads to run single commands is both inefficient and the source of your problems. <div class="pmsig"><div class="pmsig-171588"> <hr /> <font size=1 > <div>With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'</div> <div>Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.</div> <div>"Science is about questioning the status quo.
