rpc.rstatd has been left to rot for some time, and its age started
showed. E.g. it was unable to deal with the large numbers of ticks
reported for multiprocesser machines, or it crashed if a system had
no disks, or if it did not find any, which wasn't surprising as it
looked in all the wrong places, at least for current kernels.
This release changes the data acquisition layer of rpc.rstatd, making
it simpler to adapt it to changes in the operation system. In principle,
this code could even be ported more easily to other systems, by adding
a new data acquisition functions for that particular platform. There are,
however, currently no plans to do this.

This is Sun's rpc.rstatd ported to linux with a new feature and a new client
to exploit that new feature.
Authors: Adam Migus (amigus@cs.mun.ca)
Andreas Klingler (andreas.klingler@cyber-wizard.com)
Original: Sun MicroSystems.
rpc.rstatd collects kernel information on the host machine, I have ported
Sun's version of this daemon to use the proc file system. Output look similar
Output look similar to mun-ruptime (found on ftp.cs.mun.ca).
I have added the ability of extracting the number of users on the remote host
and a new "rup" client which exploits that feature.
* Both the new client and daemon remain backwardly compatible with
previous versions.
rpc.rstatd can be loaded from the command line but is usually executed via
inetd(8).
To Install:
Edit the Makefile and add the option NORPCLIB if your rpc functions are built
into libc (as they are on most linux machines). Also you will have to comment
out the call -lrpclib.
If you have a network interface other than "eth0" that appears in
/proc/net/dev, like "tu0", "sl0" etc you can define it as the interface for
rstatd to moniter by adding:
-DNET_IFACE=\"<device>\"
to the options line in the Makefile.
Append the following line to your /etc/inetd.conf
rstatd/1-5 dgram rpc/udp wait root /usr/sbin/rpc.rstatd rpc.rstatd
Tested on SuSE Linux 7.0 (kernel 2.2.16-suse18) and 7.1 (kernel 2.4).
Any bug reports, comments, etc. sent to the below address.
Release 3.07
Patch from Daniel Vesely <dan@suse.cz> to support protocol version 4 .
Configuration now via GNU configure script.
Release 3.06
Now works also with kernel 2.4 .
Some cleanups.
Added 'disk' info to rsysinfo
Release 3.05
Added option to specify which interfaces to include into the packet count.
Release 3.04
Adapted to /proc for kernel 2.2.x .
Made /proc parsing code more fault tolerant.
Writes messages to syslog and dies instead of returning false data if /proc parsing
does not work.
Some bug fixes.
BUGFIXES 3.03
Fixed incorrect numbers in ipackets, opackets, etc. for 1.2.13, and for
1.3.xx. Thanks for some help with the patch from:
Jens Maurer (jmaurer@cck.uni-kl.de)
Fixed infinite loop problem if IFACE wasn't in /proc/net/dev all the time
eg. ppp0. Stat's are now reinitialized to zero as well. Thanks for the
patch from:
Carlos Fonseca (fonseca@acse.shef.ac.uk)
I have also added a quick hack called "rsysinfo" to extract and print all
the information collected by rstatd. This is also an idea of Jens Maurer
who submitted code for the program as well.
KNOWN BUGS (if you know how to fix them email me)
With some versions of rpclib the compiled "rup" may not broadcast correctly.
This is another reason why it is recommended to use built in libc rpc stuff.
