Jinetd: inetd for Java

+ +

What is it?

+ +Jinetd does for TCP what servlet containers do for HTTP. + +

Isn't HTTP all that matters?

+ +There are now Java servers for almost every network protocol: HTTP, +SMTP, IMAP, POP3, NNTP, DNS, SSH, CIFS/SMB, and plenty of others. +Using servers written in buffer-overflow-free languages is the most +important step towards maintaining network security and stopping +worms. + +

Huh?

+ +Jinetd listens on the ports and interfaces you specify. When it +receives a connection, it loads the code designated to handle that +protocol and hands off the connection. + +

Isn't that trivially simple?

+ +While jinetd is an extremely lightweight server, it allows multiple +different network protocol handlers to share the following facilities: + +

No need for "start", "stop", or "reload" commands: +
- Automatic reloading of services when a .jar, .class, or + .java file changes; just drop in the new code or + touch the jar file to trigger a restart. + +
- Services can add their own configuration files to the + "watched" list. + +
- Connections are always accepted immediately, even if the + service's code is still initializing itself. The + connection is paused until the service finishes loading, + at which point it is handled. No more "503 Server + Unavailable" messages for your users when you restart a + context; the user just experiences a brief delay before + the webpage loads. +
+ +
Edit-in-place development +
- Automatic compilation of .java files for a service; + automatic reload once compilation completes +
+ +
Self-restart +
- jinetd is usually invoked from a "respawn" line in /etc/inittab + +
- when it detects that its .jar files have been modified, + it exits and lets init respawn it + +
- when resources run critically low (ie low memory), jinetd + will abort the JVM and let init respawn it -- the only + way to kill runaway threads in Java. +
+ +
No configuration files to edit -- host-to-service and + port-to-service mappings are inferred from directory layout. + +
Shared virtual host settings +
- Arrange your content by (virtual) host rather than by service + -- for example, the HTTP and NNTP content for + "www.megacz.com" are kept side by side in + "/jinetd/host/com/megacz/HTTP" and + "/jinetd/host/com/megacz/NNTP". +
