Gopher is a protocol for information transfer over the internet that was very popular before HTTP took over as the dominant protocol, but there is still a community of gopher users that prefer the simplicity of the protocol over the more complex and large protocols more often encountered. Note that not all browsers support gopher, or have incomplete support.
GoFish is a basic gopher server that allows you to run your own gopherspace. The setup is somewhat like other servers, but generally requires less resources to function.
Install the AUR package.
There are some basic settings for the server you can change in the
/etc/gofish.conf file, but the defaults will work. If you do not alter any settings, the root of the gopher server will be
/var/gopher and it will run on port 70. (Note that Firefox can only use the gopher protocol on port 70, so changing it will mean your users must use some other client.)
To run the server, start
You can now connect to your server and see what you have by navigating to gopher://127.0.0.1
Unlike FTP which automatically shows all files, gopher relies on a file called
.cache in each directory to determine how the page will be shown to the end user. Although GoFish comes with the man page for the
.cache files, it can be a little confusing. GoFish also comes with a program to autogenerate
.cache files for all the directories and files in your server root.
This will create all the needed
.cache files recursively, but you may want to edit some names. A sample
.cache file will look something like this:
iHello none example.com 70 0ReadMe 0/ReadMe.txt example.com 70 1Ebooks 1/ebooks example.com 70
The gopher protocol uses number prefixes to describe filetype.
0 is a plain text file,
1 is a directory and
9 is a binary file. The
i indicates an image, and if it is linked to
none, it will show up as plain text. This is good for introducing your site. See the man page for more info on the prefixes. After the prefix number is the name that will appear in the client, and it does not need to be the same as the file it links to. In the second section, we see the "path" to the file. There is not a directory named
1 in the file system, it is only added in the URI to let the gopher server and end user know what sort of file it is. The third section is whatever domain name the site is, and the fourth is the port it is on, default is 70. The space between each of the 4 sections must be a tab, not a space or it will not be parsed correctly.
Now let's look at the
.cache file in the ebooks directory.
9Book 1 9/ebooks/Book1.chm example.com 70 9Book 2 9/ebooks/Book2.pdf example.com 70
Notice that the URI is
1/ebooks/9Book1.chm . There is always only one prefix number for the last item in the URI. Also notice that a chm file nor a pdf file is really a binary, but it is still given the prefix of
9. In the GoFish server, any file that is not a text file or a directory is given the binary prefix. Remember that if there are files within your server's root, people can download or view them even if they are not in your
.cache file, so be careful.

HTTP access via Gopher proxy
You can use http://gopher.floodgap.com/gopher/gw to browse the Gopher network via HTTP, e.g. using a browser not Gopher-enabled.
