{{Admon/tip|SSHD and Firewall|If you have restarted your virtual machine ''fedora1'', the sshd server you started in section 1-16 will no longer be running. In addition, the firewall will have reverted to its original state. In order to use '''scp''', below, you will need to restart ssh and adjust the firewall again.<br /><br />If students cannot backup their kickstart files using the '''scp''' command, they can use a web-browser to access their Seneca e-mail with attachment (copy kickstart file to their home directory first!). For the text-based Linux system "fedora3", students can use the '''mail''' command (refer to the man command to learn how to send e-mail attachments).}}
