The trail mabye some issues releated with your SSH client tools but not my script as it runs pretty well under Xshell, Gnome Terminal, putty,SecureCRT etc!
Just keep your ssh client tools more newer version!
Of course, the whole algorithms and codes were designed and developed all by myself!
Version 6.0 will be released at 12/12/2012, better architecture, better optimization and new features!
Just waiting for me!
