O well. Just close <br />all windows that got opened and try again. <br /> <br />2. <br />If you didn't do the step one (ssh keys), you will be prompted <br />to enter the linux password; this increases the chances of the above <br />error. <br /> <br />3. <br />The single terminal window appearing in the Linux desktop is in fact <br />a window from your PC. <br /> <br /> Wed, 25 Jan 2006 22:13:49 GMT http://snippets.dzone.com/posts/show/1298 debedb (http://www.hrum.org)
