| There are many ways to view gopherspace. The easiest for new users is one of the following: | There are many ways to view gopherspace. Here are the easiest ways you can [[accessing web spaces#Gopher| view gopher pages from the SDF shell]] |
| | |
| ==== Use Lynx ==== | |
| | |
| [[http://lynx.invisible-island.net/|Lynx]] is the //text// web browser. \\ In addition to web browsing, Lynx is also capable of browsing gopherspace. \\ From the SDF shell, you can issue the command: | |
| | |
| $ lynx gopher://sdf.org/ | |
| | |
| and Lynx will start up at sdf.org's gopher root menu. | |
| | |
| ==== Floodgap Gopher Proxy ==== | |
| | |
| Floodgap.com provides a public gopher proxy that you can view in your web browser at https://gopher.floodgap.com/gopher/gw. \\ For more information, see the proxy info page: https://gopher.floodgap.com/gopher/ | |
| | |
| ==== Bombadillo ==== | |
| | |
| Made for browsing Gopherspace and [[gemini site setup and hosting features | Geminispace]], too, you can use the homegrown 'bombadillo' browser | |
| $ bombadillo gopher://sdf.org/ | |
| | |
| ==== SDF Gopher Command ==== | |
| |
| You can issue the gopher command, either from the SDF shell or from within the ''mkgopher'' command prompt. This can be used to create your gopherspace as described below, and also includes a very basic browser to explore gopherspace. | Additionally, you can issue the ''gopher'' command, either from the SDF shell or from within the ''mkgopher'' command prompt.

| You can use mkgopher to publish documents, create directories, etc. You can also manage your Gopherspace manually. If you decide to do so, remember that the server will not display your content if it is not already visible to everyone. That is, files need to world-readable (chmod o+r $HOME/gopher/yourfile), directories need also to be world executable (chmod o+rx $HOME/gopher/yourdir), etc. **The gopher server ([[gopher://gophernicus.org/1/software/gophernicus/|Gophernicus]]) will serve executable files under /cgi-bin and also gophermaps which have executable permission as gopher CGIs or "moles" (see below). In the case of gophermaps, this is likely to result in errors, so make sure your gophermaps do not have execute permission (chmod -x $HOME/gopher/yourdir/gophermap).** | You can use mkgopher to publish documents, create directories, etc. You can also manage your Gopherspace manually.

| The usual 'mkgopher -p' command has not yet been updated to reflect Gophernicus' permissions requirements. So you may need to reset your permissions for all files and directories in your gopher directory as noted above. The following two commands will revert all files to world-readable but non-executable, and all directories to world-readable but executable. | The usual ‘mkgopher -p’ command has not yet been updated to reflect Gophernicus' permissions requirements.

| Did you notice that fortune was called with a full path? OK, that's because the server's path is PATH=/sbin:/bin:/usr/sbin:/usr/bin. That means that if you call a program without a path, the server will search in /sbin, /bin, /usr/sbin and /usr/bin. There's no /usr/pkg/games, or other path in the server's $PATH (eventually, you can add a path of your choice with, e.g., "PATH=$PATH:/usr/pkg/games"). | Did you notice that fortune was called with a full path?
