<div dir="ltr">Dear Lubuntu group: <div> 1. How do I create a root user that I can login as and su to for my 14.04 Lubuntu system? I think it might be: sudo passwd root [prompt for my non-root password] [prompt for root password] (and repeat) And now root is a proper user with a password. There is an option for passwd in the man page :-R CHROOT_DIR - I don't understand the concept of chroot very well, but I don't think I want this, right? (I tried to see if there was an environment variable called CHROOT_DIR by typing env $CHROOT_DIR. This typed-out all the environment variables, and CHROOT_DIR is not there. But how do I look for just one such variable as I tried to do?) By the way the file /root is drwx------, and when I type 'sudo cd /root' I get 'sudo: cd: command not found' It's not an issue of a path for cd, since cd seems to be built-in. What's happening? 2. How do I "open" my 14.04 Lubuntu system (hostname west) to ftp? I have apt-get installed vsftpd, and rebooted, now when I log-in there is a daemon vsftpd running. I can successfully ftp OUT from west to another "open" linux system, and put and get files. And I can execute [ftp 204.xxx.xxx.xxx] on another machine where 204.xxx.xxx.xxx is west's ip number, and successfully "login" to ftp. Also I can cd to another directory and I can 'get' a file, But when I try to 'put' a file, I get 500 Permission Denied. My home directory on west is drwxr-xr-x [On our 12.04 KDE system, we "enabled" ftp by apt-getting vsftpd, adding 'write_enable=YES' in /etc/vsftpd.conf and restarting vsftpd by typing 'sudo /etc/init.d/vsftpd restart'. So: I uncommented #write_enable=YES in /etc/vsftpd.conf And then to restart the vsftpd daemon, I typed sudo /etc/init.d/vsftpd restart I got 'command not found'. I have seen the word 'service' somewhere, so I man'ed service, and then typed sudo service /etc/init.d/vsftpd restart I got "/etc/init.d/vsftpd: unrecognized service" Then I man'ed 'systemd", but there was no man page. How do I do the equivalent of sudo /etc/init.d/vsftpd [option] now? Thanks, gary knott, <a href="mailto:garyknott@gmail.com">garyknott@gmail.com</a> </div></div>
