dnetc is a distributed computing client that coordinates with servers operated by distributed.net to cooperate with other network-connected computers to work on a common task. It communicates over public networks and processes work assigned by the distributed.net keyservers. It is designed to run in idle time so as to not impact the normal operation of the computer.

Since you are already reading this, I assume you know how to unpack an archive into a directory of your choice. :)

Now, simply fire up the client...

If you have never run the client before, it will initiate the menu-driven configuration. Save and quit when done, the configuration file will be saved in the same directory as the client. Now, simply restart the client. From that point on it will use the saved configuration.

The configuration options are fairly self-explanatory and can be run at any time by starting the client with the '-config' option. A list of command line options is listed below.

In addition to the conventional command line passed to the client from a shell, options may also be passed to the client using either or both of the following methods:

- using the dnetc_opt= environment variable.

If set, this is parsed before the normal command line.

- using the //etc/distributed-net.conf

command files. If found, these are parsed after the normal

command line.

"Mode commands" (see below) cannot be executed using these methods, and there is no run-time display of modified settings (unless the settings are also modified using the conventional command line, in which case the last effective change is displayed).

start the configuration menu
flush all output buffers
fill all input buffers
fetch + flush
[prj]
16-20 sec speed check [optional: only project prj]
[prj]
half (8-10 sec) and slightly inaccurate -benchmark
[prj [cn]
-benchmark all cores [optional: only project prj]

[optional: only core cn, must be used with prj]

[prj [cn]
tests for core errors [optional: only project prj]

[optional: only core cn, must be used with prj]

[prj [cn]
more thorough and longer running variant of -test
print information about the detected cpu(s)
restart all active clients
gracefully shut down all active clients
pause all active clients
unpause all active clients
[...]
install the client in /etc[/rc.d]/init.d/

all [...options...] that follow '-install' serve

as parameters for the installed client.

remove the client from /etc[/rc.d]/init.d/
<filename>
import packets from file <filename> into client buffers
<fn>
unlock buffer file <fn>
display this text
print version information
<filename>
override default name of INI file
<address>
the email id by which you are known to distributed.net
don't use disk buffer files
<count>
packets to complete. -1 forces exit when buffer is empty.
set -n == -1 (exit when buffers are empty)
frequently check if buffers need topping-up
<fname>
input buffer basename (ie without 'extension'/suffix)
<fname>
output buffer basename (ie without 'extension'/suffix)
<fname>
set the name of the checkpoint file
<prj> <n>
set fetch buffer threshold to <n> work units
[prj <n>]
set fetch time threshold to <n> hours

If not specified, project name <prj> defaults to RC5

disable network access
enable network access
<secs>
set the network timeout. Use -1 to force blocking mode
<address>
keyserver name or IP address
<port>
keyserver port number
don't fallback to a distributed.net keyserver
<method>
use this UUE/HTTP encoding method (see -config)
<address>
http/socks proxy name or IP address
<port>
http/socks proxy port
automatically detect modem connections
perform buffer updates only when a connection is detected
<list>
limit the interfaces to monitor for online/offline status
[prj <n>]
core number (run -config for a list of valid core numbers)

project name 'prj' defaults to RC5

<n>
run <n> threads/run on <n> cpus. 0 forces single-threading.
<n>
run on device <n> only.
<0-9>
scheduling priority from 0 (lowest/idle) to 9 (normal/user)

<filename>
name of the log file
<len>
max size (in bytes) of a mail message (0 means no mail)
<host>
name or IP address of mail (SMTP) server
<port>
mail (SMTP) server port number
<id>
who the client should say is sending the message
<id>
who the client should send mail to

<hours[:min]>
time limit in hours
<HH:MM>
quit at HH:MM (eg 07:30)
override .ini exit flagfile setting
<fn>
name of file that causes the client to pause
<fn>
name of file that causes the client to exit
allow/disallow multiple instances of the client to run

The default is 'allow' for all platforms but Windows.

don't display work completion as a running percentage
suppress screen output (== detach for some clients)
don't suppress screen output (override ini quiet setting)

distributed.net maintains a database to assist with the tracking and resolution of bugs in dnetc and related software.

If you believe you have found a bug, please submit it to the distributed.net bug tracking database at http://bugs.distributed.net/

Please provide the entire version descriptor as displayed on client start when doing so. For example, the client version this manpage was generated for was "dnetc v2.9112-521-CFR-16020313 for Linux".

dnetc_opt (or the upper-case version thereof)
