Re: Apache cgi-bin config

You also need to put cgid.conf and cgid.load in /etc/apache2/mods-enabled. sudo a2enmod cgid I would leave the ownership of /usr/lib/cgi-bin or /var/www/html as root:root. The cgi-bin programs I would chmod 750 and have them owned by www-data:www-data. Your html files can be owned by pi if you want.

Re: Walkthrough Of a Piece of Code

It's a shell script. case and esac are the opening and closing of the case statement. start and stop are the two possible cases. If you run the script "vncboot start" it follows the code at start) and the same for stop). I'm not sure whether *) is no command line option or any command line option.

postfix resolv.conf file empty on startup?

So when I start my Pi3, postfix starts but it can't find any DNS servers and so it leaves /var/spool/postfix/etc/resolv.conf empty. As a result my emails don't go anywhere. If I restart postfix it populates resolv.conf and everything works great. I am clueless about systemd and startup. Is there a w...

Re: Setting up vsftpd

It didn't work, but I believe port 20 is closed. Is it supposed to be TCP or UDP? FTP uses TCP connections. Port 20 is closed on which machine, your server or your client? It is an outbound connection from the server and an inbound to the client. From Wikipedia: "FTP may run in active or passive mo...

Pi3 stutters over WiFi?

My Pi3 stutters, it stops for a few seconds and then continues when connected through the WiFi. The pause can last for as much as about 15 seconds and occurs as often as 3 or 4 times per minute. If I'm connected through ethernet it runs smoothly and never falters. The software is up to date. Any ide...

Re: Setting up vsftpd

So the problem here is that chrooting the user has security issues (that I don't really understand) so the chroot directory cannot be writeable. The easiest way to fix that is to make ftp's root directory permissions 555. You will still be able to have writable subdirectories under /home/ftp. You di...

Re: Setting up vsftpd

First active and passive are how the connection and data transfer is accomplished. Not what you are concerned with here. Look at the vsftpd, conf file for the chroot options and the user access files to force the user into his own directory structure. You can also set a list of users that have ftp a...

Re: Give pi account sudo access to www?

It's really much simpler to just put another directory under /var/www such as /var/www/pi and have it owned by pi. Then you can ftp or sftp your files right to the website directory. When you set up your apache use /var/www/pi as the document root.

There are two options for VNC, first is tightvncserver which will give you a virtual desktop and x11vnc which will repeat the actual desktop.

Re: Static address - still dhcp

This is one of the hardest things about Linux. Stuff tunes along for ever working one way and then they change it up on you.

If you are using Jessie or a late Wheezy then you need to clean all that stuff out of your /etc/interfaces file and read man dhcpcd.conf for how to set it up now.

Re: Disabling dns on raspbian

I can't imagine why you would want to disable the DNS? I think you do it by editing /etc/dhcpcd.conf, from the docs nohook script Don't run this hook script. Matches full name, or prefixed with 2 numbers optionally ending with .sh. So to stop dhcpcd from touching your DNS settings or starting wpa_su...

Re: Configuring Apache2 for CGI

Make sure that you have a link to /etc/apache2/conf-available/serve-cgi-bin.conf in /etc/apaqche2/conf-enabled, and that there are links to /etc/apache2/mods-available/cgid.conf and cgid.load in /etc/apache2/mods-enabled. Assuming you didn't change the defaults, your CGI programs belong in /usr/lib/...
