cachesrv is a web server that serves the current working directory using a file cache to speed up commonly-accessed files.
cachesrv is based on a file
cache I wrote in Go.
cachesrv has been tested on the following operating systems:
- OpenBSD (5.2)
- OS X (10.8)
go install will install the binary to the ${GOROOT}/bin directory.
cachesrv [options] [dir]
Valid options:
-c certfile specify the TLS certificate
-d duration dump cache stats duration; by default, this is turned
off. Must be parsable with time.ParseDuration.
-e seconds seconds to expire cache items after; 0 to never expire
due to time in cache
-g seconds seconds to delay between checks for expired items in
the cache.
-k key specify the TLS key
-n items maximum number of files to store in cache
-p the port to listen on
-r the server should chroot to the target directory
-u user the server should drop privileges to this user
-v display the version and exit
Specifying a key and certificate will cause the server to listen in TLS mode.
Use ^C to halt the server.
From chroot(2):
This call is restricted to the super-user.
The server uses root privileges to chroot to the target directory, then immediately drops privileges.
setgrp isn't implemented here, as no good solution exists in Go.
This is version 3.0.0 of the srvwd file server. The original
version
(the 1.x series) was written in C; a subsequent rewrite in
Go (the 2.x series) used only the standard
library to serve files. This version, the 3.x series, uses a file
cache to speed up commonly accessed files.
