login_keepalived is a small daemon that keeps remote terminal logins alive.

I wrote this because my remote ssh sessions where repeatedly being cut off after a few minutes of inactivity, it seems by some router/firewall on the Internet which I couldn't control.

The idea is to have a daemon on the server write a NULL character to logged in terminals every minute.

This has no effect on terminal sessions, but keeps TCP sessions alive preventing timeouts / aborts. It can be run as a global daemon keeping all terminals alive, or as a private daemon servicing only an individual terminal.

Currently runs on Linux but should be easy to port to other *nixes.

Installation:

The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation.

It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions.

Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, a file `config.cache' that saves the results of its tests to speed up
reconfiguring, and a file `config.log' containing compiler output (useful mainly for debugging `configure').

If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release.

If at some point `config.cache' contains results you don't want to keep, you may remove or edit it.

The file `configure.in' is used to create `configure' by a program called `autoconf'. You only need `configure.in' if you want to change it or regenerate `configure' using a newer version of `autoconf'.

The simplest way to compile this package is:

1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system.

If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself.

Running `configure' takes awhile. While running, it prints some messages telling which features it is checking for.

What's New in This Release:
New option: -s where = seconds to sleep between keepalive-writes
Switched to using getopt() for parsing commandline arguments
Added config.h
