## install
|
|
|
|
you have three options:
|
|
|
|
### Option 1: Prebuilt binary
|
|
|
|
prebuilt binaries for darwin and linux architectures arm/amd-64 are provided since v0.5.4. Head over to the tags page on git.sr.ht, click on a desired tag and download the binary for your architecture.
|
|
|
|
=> https://git.sr.ht/~hedy/spsrv/refs
|
|
|
|
|
|
### Option 2: with go
|
|
|
|
first, you need to have go installed and have a folder ~/go with $GOPATH pointing to it.
|
|
|
|
```
|
|
go install git.sr.ht/~hedy/spsrv@latest
|
|
```
|
|
|
|
there will be a binary at ~/go/bin/ with the source code at ~/go/src/
|
|
|
|
feel free to move the binary somewhere else like /usr/sbin/
|
|
|
|
note that it's recommended to pin any latest version `@v0.0.0` rather than the latest commit since it may not be stable.
|
|
|
|
|
|
### Option 3: just build it yourself
|
|
|
|
run git clone https://git.sr.ht/~hedy/spsrv from any directory and cd spsrv
|
|
|
|
make sure you have go installed and working.
|
|
|
|
```
|
|
git checkout v0.0.0 # recommended to pin a specific tag
|
|
make build
|
|
```
|
|
|
|
when it finishes, the binary will be in ./bin.
|
|
|
|
if you don't have make, you can just `go build` (just that version and build information will not be available with `spsrv --version`).
|
|
|
|
### otherwise...
|
|
|
|
if you do not wish to install go or clone the repo, and your architecture is not supported in the prebuilt binaries, drop an email to my public inbox (or contact me privately) so I could perhaps compile a binary for your architecture.

## configuration
|
|
|
|
The default config file location is /etc/spsrv.conf you can specify your own path by running spsrv like
|
|
|
|
```
|
|
spsrv -c /path/to/file.conf
|
|
```
|
|
|
|
You don't need a config file to have spsrv running, it will just use the default values.
|
|
|
|
config options:
|
|
|
|
Note that the options are case insensitive.
|
|
|
|
Here are the config options and their default values
|
|
|
|
### general
|
|
|
|
port=300: port to listen to
|
|
|
|
hostname="localhost": if this is set, any request that for hostnames other than this value would be rejected
|
|
|
|
rootdir="/var/spartan": folder for fetching files
|
|
|
|
### directory listing
|
|
|
|
dirlistEnable=true: enable directory listing for folders that does not have index.gmi
|
|
|
|
dirlistReverse=false: reverse the order of which files are listed
|
|
|
|
dirlistSort="name": how files are sorted, only "name", "size", and "time" are accepted. Defaults to "name" if an unknown option is encountered
|
|
|
|
dirlistTitles=true: if true, directory listing will use first top level header in *.gmi files instead of the filename
|
|
|
|
### ~user/ directories
|
|
|
|
userdirEnable=true: enable serving /~user/* requests
|
|
|
|
userdir="public_spartan": root directory for users. This should not have trailing slashes, and it is relative to /home/user/
|
|
|
|
userSubdomains=false: User vhosts. Whether to allow user.host.name/foo.txt being the same as host.name/~user/foo.txt (When hostname="host.name"). NOTE: This only works when hostname option is set.
|
|
|
|
### CGI
|
|
|
|
CGIPaths=["cgi/"]: list of paths where world-executable files will be run as CGI processes. These paths would be checked if it prefix the requested path. For the default value, a request of /cgi/hi.sh (requesting to ./public/cgi/hi.sh, for example) will run hi.sh script if it's world executable.
|
|
|
|
usercgiEnable=false: enable running user's CGI scripts too. This is dangerous as spsrv does not (yet) change the Uid of the CGI process, hence the process would be ran by the same user that is running the server, which could mean write access to configuration files, etc. Note that this option will be assumed false if userdirEnable is set to false. Which means if user directories are not enabled, there will be no per-user CGI.
|
|
|
|
Check out some example configuraton in the examples/ directory.

## CLI
|
|
|
|
You can override values in config file if you supply them from the command line:
|
|
|
|
```
|
|
Usage: spsrv [ [ -c <path> -h <hostname> -p <port> -d <path> ] | --help | --version ]
|
|
|
|
-c, --config string Path to config file
|
|
-d, --dir string Root content directory
|
|
-h, --hostname string Hostname
|
|
-p, --port int Port to listen to
|
|
```
|
|
|
|
Note that you cannot set the hostname or the dir path to , because spsrv uses that to check whether you provided an option. You can't set port to 0 either, sorry, this limitation comes with the advantage of being able to override config values from the command line.
|
|
|
|
There are no arguments wanted when running spsrv, only options as listed above :)
|
|
|
|
## CGI
|
|
|
|
The following environment values are set for CGI scripts:
|
|
|
|
```
|
|
GATEWAY_INTERFACE # CGI/1.1
|
|
REMOTE_ADDR # Remote address
|
|
SCRIPT_PATH # (Relative) path of the CGI script
|
|
SERVER_SOFTWARE # SPSRV
|
|
SERVER_PROTOCOL # SPARTAN
|
|
REQUEST_METHOD # Set to nothing
|
|
SERVER_PORT # Port
|
|
SERVER_NAME # Hostname
|
|
DATA_LENGTH # Input data length
|
|
```
|
|
|
|
The data block, if any, will be piped as stdin to the CGI process.
|
|
|
|
Keep in mind that CGI scripts (as of now) are run by the same user as the server process, hence it is generally dangerous for allowing users to have their own CGI scripts. See configuration section for more details.
|
|
|
|
Check out some example CGI scripts in the examples/ directory.
|
|

|
|
|
|
Example systemd service configurations are also listed there. Feel free to contribute for other OSes :)
