This release of the v2 Personal Proxy will allow you to serve all recent v2 distributed.net Bovine clients. It allows you to establish one of your own machines as a buffer between your clients and one of the "full servers" (keyservers) that are officially run by the distributed.net organizers. This will allow your clients to waste less time trying to connect to one of the main proxies, since the personal proxy will already have more key blocks waiting for your clients when they're ready and need more. Running a personal proxy is definitely not needed by everyone, nor is it recommended. You should only run a personal proxy if you are very confident of your abilities, and you have a very weak, unreliable, or intermittent connection to the Internet to directly contact one of the real proxies.
Personal proxies are distinguished by the "build number" that is associated with each new version.
- OGR-26 and up (OGR-NG) requires proxy build 344 or greater.
- RC5-72 requires proxy build 330 or greater. Large-size RC5-72 blocks requires proxy build 346 or greater.
- Proxy build 335 or higher will only communicate with clients v2.8015.469 or higher.
- Proxy build 341 or higher will only communicate to upstream servers of build 341 or higher.
The personal proxy uses buffer files to store all blocks that are pending distribution to client, or awaiting transfer to an upstream server. Every effort has been made to keep the format of these buffers consistent across proxy versions, platforms, and operating systems. There are currently 3 main types of proxy buffers that you need to keep in mind before you considering transporting buffers:
Format A: up to and inclusive of proxy build 283.(obsolete)Format B: proxy build 300 through 304, inclusive.(obsolete)- Format C: proxy build 305 to current, inclusive. (current)
Format A is completely obsolete. Format B used an experimental filesystem-like buffering system, but was abandoned due to stability issues. Format C uses a less resource demanding buffering format more appropriate for personal proxy use.
Buffers from any operating system or cpu architecture from a proxy that creates the same "format" above should be transportable. Note that "transportable" does not mean that you can "share" buffers between two simultaneously running copies of the proxy!!
If you are upgrading to a new proxy version that uses a file format that
is incompatible with the last version you were using, there is no way to
convert them. You must flush all blocks from the existing proxy buffers.
To do this, set maxkeysdone=1, then start the proxy. It should flush all
blocks to the keyservers. If you don't want clients to connect to your
proxy during this process, set the acceptincoming-flag in the [ports]
section to 0 (zero).
After you see a logentry with rc5-72 r=x/x, d=0/1 you know your
buffers are empty. Shutdown the proxy and delete all bufferfiles
(ppdes*.des and pprc5*.rc5) It is safe to simply delete the inbuff
files, even if they have keys left in them. They will eventually be
reissued.
If you have blocks within an "out" buffer, and cannot flush them, please rename the file to something else or delete it.
Since you have this file, you probably have already downloaded and unpacked the proper distribution for your machine. If not, see ftp://ftp.distributed.net/pub/dcti/proxyper/ and download the proxy package for your machine. Once the proxy is unpacked, you will need to configure it. You may rename the binary to anything you like, but there must be a corresponding config file with ".ini" as a suffix. Then edit the .ini file with your favorite text editor (configuration options are listed in the next section), and then start the personal proxy in the directory you have installed it in. The log and dump files will be created in this directory. Hint: If you specify a relative path for a logfile entry in the .ini, the logs will be created in a directory relative to the current directory.
Edit the ini file with a standard text editor and verify the settings. Depending upon the number of clients you are serving, you may want to increase or decrease the number of keyblocks that are kept in memory. Note that the proxy uses a sliding average that prevents you from buffering more than 4 days worth of blocks. These numbers will be adjusted according to your keyrate and should be reasonable stable after 30 minutes after you started the proxy.
Note that the ini file is only read once (as the proxy starts up). Modifications made to the ini file will not take effect until you terminate and restart the proxy. On most platforms, there is a method to trigger the ini file to be reloaded at will. See the "operations and signals" section to determine the method that is applicable for your operating system.
None of the settings in the ini file are actually required to be specified. All of the settings have default values that should work for most people. However, it is still recommended that you verify and explicitly set all of the options.
Although we try to keep the format of the ini file consistent between different builds of the proxy, there are occasionally changes made between builds that affect the options that are available. Build 300 of the proxy introduced a fair number of significant differences in the ini file, so be aware of these differences and compare your current ini to the one that comes with the new proxy-tarball.
The personal proxy requires you to specify the minimum and maximum number of "blocks" that it should try to keep ready at all times for clients. However, when you specify the numbers for these two values, please be certain that you only enter values that are reasonable for the number of clients that you are planning to support.
Specifying numbers that are too large may cause your proxy to buffer a more blocks than your installed client-base can use in a realistic amount of time. It is important to avoid fetching too many extra blocks to reduce the likelihood of a large number of blocks getting wasted if your proxy crashes, or you decide to discontinue running a proxy. Additionally by buffering a large number of blocks, you increase the number of outstanding blocks that must be tracked and managed by the key distribution system, which limits many aspects of distributed.net's performance. On the other hand, specifying too few blocks will make it more likely that your clients will run out of legitimate blocks should short-term network outages occur, forcing them to compute randomly generated blocks, which would have a greater possibility of being duplicated by other machines.
In general, it is recommended that you buffer no more than about 3 or 4 days worth of blocks, so that you could potentially withstand a network outage that long in the worst case. There is typically no reason to want to buffer any more blocks than that. The appropriate number is of course dependent upon the number and speed of clients that you have connecting to your personal proxy, so you will have to determine this value experimentally.
Builds prior to 305 of the personal proxy placed somewhat restrictive maximum ready block limit of 10000, for the purpose of preventing people from accidentally specifying an extremely large number of blocks before realizing that it was too great to support their number of clients. Unfortunately, this also limited the effectiveness for people who were legitimately using the personal proxy to support an extremely large number of clients.
Starting with build 305, the maximum ready buffer limit has been increased to 200000 blocks, however additional logic has been added to prevent accidentally fetching an inappropriate number of blocks:
- If you specify a buffer limit of 1000 or fewer, the proxy will respect this value, just like previous versions.
- For values larger than 1000, the proxy will internally treat the maximum ready value as if 1000 had been entered, until the proxy has been running for a period 30 minutes total.
- Beginning after 30 minutes of uptime, the proxy will periodically evaluate your average keyrate and allow maxready values as large as that sustained rate for 4 days to be specified. If the value entered within the ini file is less than the computed sustained usage count, then the value you specified will be obeyed.
Additionally, when your maxready value is being suppressed by the proxy, it will simultaneously adjust the minready in an equivalent proportion so that the ratio that was originally specified is maintained. As you can see, the complexity has increased slightly, but the flexibility has also been improved at the same time. You should keep this behavior in mind when trying to configure your ready buffer thresholds.
This automatic behavior is recommended for almost all people. The proxy will adjust its buffer so there's always enough blocks for a couple of days. People who use the proxies buffers to sneakernet need be to able to download large numbers of blocks. For this purpose a ini-setting [rc5-72]/expertmode and [ogr-ng]/expertmode is added. If this option is set to 1 (one), the proxy will obey your settings of maxkeysready and minkeysready.
[KeyServer]/ipaddress: the IP address or hostname of the keyserver from which the proxy will retrieve and send keyblocks from.
[KeyServer]/port: the port on the keyserver to communicate to.
[KeyServer]/connectperiod: determines the minimum delay (in seconds) between sequential attempted network connections to the keyserver. This value should typically *not* be adjusted to more than a couple of minutes, but it should also not be made too short, or else your proxy might attempt to make a connection as frequently as this amount, which may prevent it from handling incoming client connections if your proxy is unable to successfully make outgoing server connections.
[KeyServer]/connectivity: these modes are very much like the normal, offline, lurk, and lurkonly modes that are available on the windows clients. This option only has effect on the win32 version of the proxy.
normal: The proxy will attempt to connect to a server as needed.offline: The proxy will not attempt to make any connections to a server automatically.lurk: The proxy will automatically send/receive blocks when it detects a network connection, but it may also initiate connection by itself if it needs to send or receive blocks. If you have autodial configured, then your modem will auto-dial.lurkonly: Same as lurk, however the proxy will not attempt to make connections unless it can explicitly detect that your modem is currently connected, so it won't ever cause auto-dial.
If you are behind a firewall and must use a proxy to make a connection on either a telnet or http port, the following options will be useful.
-
[KeyServer]/uuehttpmode:
0=no special encoding, 1=uue encoding (non 8-bit clean redirect proxies), 2=http encoding, 3=uue+http encoding, 4=socks4 encoding, 5=socks5 encoding, 6=generic proxy, 7=generic proxy with uue encoding.For an explanation on generic proxy support, see below. -
[KeyServer]/httpproxy: The name of your site's http or telnet proxy.
-
[KeyServer]/httpport: The port to connect to the above proxy on.
-
[KeyServer]/httpid: User and password authentication needed to connect to the above proxy. This field must be set to the *encrypted* value of the username and password information. In order to get this value, use the client's configuration option to specify the username and password, then cut and paste that field from the client .ini to your proxy .ini. Remember to restore the client configuration when you are all done with this. For socks4 httpid is the
usernamein plaintext. For socks5 httpid is theusername:passwordin plaintext. For generic proxy, this is the connection negotiation string. -
[KeyServer]/bindip: Specifies the local interface address that should be bound to when creating outgoing server connections. This might be useful if your machine has multiple interfaces and you wish to listen for incoming clients on an internal network, and make outgoing internet connections on a public network interface. If you leave this option unspecified, it allows the network stack to do default interface and routing rules to create connections.
-
[KeyServer]/maxservers: Determines the maximum number of simultaneous upstream server connections will be used to fetch or flush. It might be useful to increase this number if you frequently need to upload or download a large number of blocks at a single time, and it seems that individual server connections are slow or have high latency. The default value is 1 and the maximum number you can specify is 4.
[ports]/listenaddress: The IP address of the machine this personal proxy is running on. This is optional and only needed if the machine has multiple IP addresses. If you use one ip address for local connections, and you have a dialup account that you use to fetch and flush blocks, you do *not* need to set this.
[ports]/port: the port on *your* machine to listen for incoming clients on.
[ports]/port2, port3, port4: these allow you to specify additional listening ports on *your* machine to listen simultaneously for incoming clients on. Typically these additional ports aren't needed, but this ability is here if you need it.
[ports]/testport: the port on *your* machine to listen for incoming clients on and distributed test blocks to. This value can be unspecified, or set to 0 to disable this functionality.
[ports]/acceptincoming: if this is set to 0, clients will not be able to connect to the proxy at all. Defaults to 1.
[ports]/advertisedaddress: This value is normally not needed and is only needed if you are having problems serving HTTP clients and your personal proxy machine has a different address by which it is reached on than what it listens on. (This is usually the case when you are attempting to serve clients with a machine behind a NAT firewall, or a port-redirected environment.) This value should be the public IP address that is usable by clients to connect back to your personal proxy with. If you do not specify this value, the value you specified for the listenaddress is used, otherwise no address is used.
[ports]/timeout: This value can be used to set maximum idle timeout for client connections. Default is 30 seconds. Change of this value normally is not required. You can try to increase timeout if default value is not enough for your client (e.g. it having a long time-consuming benchmark on unknown cpu.)
[misc]/statusperiod: this is the number of seconds between the status reports from each of the current contests are printed out to the console log. The contest status reports indicate the number of current ready and done blocks, their set values, and also the sliding window average keyrate, and total number of completed blocks since startup.
[misc]/periodicperiod: this is the number of seconds between the rewriting of the proxy buffers to disk. If you have a machine with a very slow disk or has a bus with high I/O contention, you may want to increase this value to trigger writes only every few minutes. Note that when you allow the proxy to shutdown gracefully, it will automatically rewrite it buffers out again if necessary (regardless of when the last periodic write occurred).
[misc]/logfilecompressor: the name of a script or program to run once per log file rotation with one parameter, the name of the just completed log file. This function is enabled since build 305.
[misc]/proxymessage: an optional text message displayed to all connecting clients. If you leave this value blank or unspecified, a default message including the build number will be displayed to clients.
[misc]/pidfile: if specified, this is the filename that will have the process id (pid) of the proxy when it is started up. This is only for Unix perproxies.
[misc]/scheduledupdate: this is an internal value is is automatically updated and maintained by the proxy itself each time it connects to the keyserver. You should not modify or adjust this value.
[console]/logfileconsole: name of console log file
[console]/logfileconsolerotation: interval to rotate console log at, options are none, hourly, daily, monthly, yearly, or startup
[console]/consoleverbosity: control verbosity of the console log output. It is specified with a list of space-separated keywords:
all: display all message types (default)none: no console output at allgeneral: General logging (Status: Slot X LISTENING, and others)stats: Periodic statistics reportskeyblock: Block numbersserver: Upstream keyserver communicationsclient: Downstream client communicationsbuffers: statistics (ready=X/X, done=X, Xd XX:XX:XX, X.X Mkeys/sec)timestamp: Include UTC timestamps on each line (screen only)attention: Keyspace change, time change, dialup eventserrwarn: Unrecognized opcodes/versionerrlow: Invalid settingserrsevere: Operation inhibiting problems
If the very first keyword is not, the verbosity will be all, minus
the keywords specified. For example, not keyblock client will prevent
messages in the keyblock or in the client categories from displayed; all
other messages are displayed.
[console]/timestampflags: controls the format that is used to
display timestamps on screen, logged in the console log, and logged in
keyblock logs. Note that timestamps in the onscreen console log can be
hidden entirely with the consoleverbosity option above. The integer
that is specified for this value is actually the result of adding one of
the format mode values, plus optionally one or more of the additional
flags. The format mode values available are:
| style | format | mode value |
|---|---|---|
| old-style | MM/DD/YY HH:MM:SS |
1 |
| new-style | YYYY-MM-DD HH:MM:SS |
2 |
| client-style | Mmm DD HH:MM:SS |
3 |
And the multiple flags that you can choose are:
| flag | flag bit value |
|---|---|
| show timezone name | 64 |
| timestamps should be in UTC | 128 |
Note that the "show timezone name (64)" only has an effect if timestamps are being "displayed in UTC format (128)". When that is the case, the letters "UTC" will be appended to all timestamps that are displayed on-screen (not in console log files, or keyblock files).
The default format is 193, and will provide output that is identical to that used by personal proxies before build 313.
Also notice that the timestampflags will not affect the numbering sequence used to generate filenames for automatically rotated logfiles. Rotated log filenames are always generated from the current UTC time.
Be aware that changing the timestamp format may affect your ability to use log parsing or log processing utilities. You should contact the authors of your utilities to obtain a version that is able to parse the new 4-digit year format, and accommodate localtime timestamps.
[rc5-72]/logfilekeyblock: name of log file of all completed keyblocks
[rc5-72]/logfilekeyblockrotation: interval to rotate keyblock log at, options are none, hourly, daily, monthly, yearly, or startup
[rc5-72]/maxkeysready: approximate maximum number of keys to keep ready for serving clients.
[rc5-72]/minkeysready: minimum number of keys to keep ready for serving clients. This differs from the maxkeysready in that once the available keys drops below this value, the proxy will "try harder" to fetch additional keys from the server.
[rc5-72]/maxbufferdays: the personal proxy by default will buffer as much blocks needed for 4 days. If you want to change this default behavior, this option specifies the number of days the proxy should buffer blocks for.
[rc5-72]/minkeysdone: number of completed key blocks that will always be kept resident and not transmitted. There is probably no reason for this to be anything other than 1.
[rc5-72]/maxkeysdone: number of completed key blocks that must be done before an outgoing connection to the keyserver is made to flush the completed blocks.
[rc5-72]/timeaverage: number of chunks to use for the sliding-average window. The default is 288 (1 week in 5 min chunks), the valid range is 6-2016 (5 hour - 1 weeks).
[rc5-72]/timeavgchunk: number of seconds to use for a chuck in the
sliding-average window. The default is 300 (5 minutes). Valid range is
between 1 minute and 30 minutes. This option is added for people who
desperately need a window bigger than 1 week. Be aware that changing the
defaults of timeaverage and timeavgchunks is not recommended. Too
high values can lead to an increase in resources needed to track the
stats.
[rc5-72]/contestclosed: participation in the contest can be entirely disabled by setting a negative value
[rc5-72]/blocksize: the preferred size of blocks when requesting
additional workunits from the upstream server. The default is 256. If
clients need smaller block sizes, then your proxy will automatically
split large blocks into the needed size, however clients will not be
able to request blocks larger than the size your proxy currently has
available, since the proxy cannot combine smaller blocks together. Be
aware that when your proxy requests additional workunits from the
upstream server, this blocksize value may cause your proxy to
temporarily exceed the maxkeysready since requests will always be done
in multiples of this value.
[ogrng]/[ogrp2]/[desII]/[csc]/[ogr]/[rc564]
see the [rc5-72] section for the entries that you can put here, and
what they do....
[ignoredip]/[allowedip] These two sections provide functionality for allowing and denying certain ipaddresses or ipaddress ranges. The rules are:
a. if there are entries in [allowedip], only allow clients in that section, else
b. if there are entries in [ignoredip], deny all clients in that section, else
c. allow the connection
This is equivalent with the behavior of the tcpd wrapper in Unix systems.
After the section header, ip(-ranges) are listed in the form:
anything=1.2.3.4,maskbits
one line for each block of IP addresses you want to ignore. To ignore a class C subnet (255 addresses, x.x.x.*, /24), maskbits will be 24. For an entire B network (65536 addresses, x.x.*.*, /16) you will want to use a maskbits of 16. Note that this format is different from the format that was used in build 280 and prior of the personal proxy.
Additionally, you can enter masks using any of these forms:
anything=1.2.3.* anything=1.2.*.* anything=1.*.*.*
Build 306 of the personal proxy introduced a new method of firewall compatibility communications, known as "generic proxy" (a name also used by the programs CRT and SecureCRT). This new method of communication allows you to establish redirected TCP/IP connections through an intermediate machine/proxy that requires a login or negotiation sequence. This includes connecting to a gateway machine to log in and then telnetting to the destination keyserver, and also connecting through a WinGate "telnet proxy" that requires you to specify the destination hostname and port.
In the generic proxy modes, the interpretation of the "httpid" value is changed to represent the login sequence string, which is merely a vertical-bar ("|") delimited string of alternating things to transmit, and things to wait for. Note that the first sequence in the string is assumed to be a send string, so if you don't need to send anything first just include a vertical-bar as the first thing in the httpid. The tags \n, \t, \r, \1 (keyserver address), and \2 (keyserver port) can only be used in send strings. Be aware that the maximum length of the entire httpid string is very limited, so you cannot include sequence strings that are too complicated currently. Also understand that since the sequence string is of course stored in plaintext in your ini file, if you include connection passwords, they could be compromised if you do not protect your ini file.
One example for connecting to a gateway machine is:
"|login:|bovine\n|Password:|moocow\n|%|telnet \1 \2\n"
An example for a WinGate telnet proxy is:
"|WinGate>|\1 \2\r\n"
While the proxy is running, it displays countless numbers of messages to indicate its current status. Because of the potentially large volume of messages that can be generated, a console verbosity option has been added to the proxy ini files to allow you to select only specific classifications of messages to be displayed.
There are also methods for causing the console output to be saved to a file, either for remote log viewing purposes or record keeping. Although there exist a number of third-party utilities that permit the user to analyze console logs to produce statistics regarding your proxy's operations, though console logs were not really intended for any type of mechanical analysis. The format and style of the console messages are purely intended to be human readable and will tend to be modified slightly between proxy builds.
Some messages explained:
-
contest <contest> r=<a>/<b>, d=<c>/<d>, <avg>Mkeys/s, total=<blocks>a/b = a blocks currently in inbuffer, b is threshold. c/d = c blocks done, d is threshold
-
Server xx.xx.xx.xx changed state from x to xstate 0 is a no connection state 1 is waiting for connection to be set up state 50 is a connected connection state 51 is a dead connection
-
Contesthandler <contest> didn't handle a packetFor some reason the proxy couldn't process a clientrequest for a packet (block). Most of the time due to empty proxybuffers
-
Client: rejecting unscrambled communicationClient tries to send a packet that doesn't comply. Most of the time due to too old clients
The personal proxy will also output so-called "key logs" which record details of each completed block that is reported to it by a client. These files are intended for automated processing and so they have a very regular, comma delimited formatting. Each line of a key log has the following fields, in order:
- date/timestamp of format, such as "mm/dd/yy hh:mm:ss". The actual format can be changed via the [console]/timestampflags option
- IP address of the reporting client
- email address of the client
- unique identifier representing the completed packet. For RC5-72, this is a hexadecimal string with embedded colons in the format "xx:xxxxxxxx:xxxxxxxx". For RC5-64/DES/CSC, this is is a hexadecimal string (14 to 16 hexadecimal digits). For OGR, this is a variable-length string resembling the format "dd/dd-dd-dd-dd-dd"
- size of the packet. For OGR, this is the number of nodes within the stub. For RC5-72, this is the number of number of "blocks" in the packet (where each block is 2^32 keys). For RC5-64/DES/CSC this was also the number of "blocks" in the packet, but each block was 2^28 keys.
- operating system identifier of client (0=unknown).
- cpu type of client (0=unknown).
- build/version number of client. For clients released before rc5-72, this is only the middle segment of version number. For rc5-72 enabled clients, this contains the full fractional version number and build of the client.
- project cruncher core number.

See bottom of this document for a list of OS and CPU types and numbers.
On UNIX, sending a TERM or INT signal will cause the personal proxy to
shut down nicely, re-saving all keyblocks that are still in memory to
disk, and closing all open network connections.
On UNIX, sending a HUP signal will cause the personal proxy to reload
its ini configuration file and reread most of the settings specified
within it.
On UNIX, sending an ALRM signal will trigger the personal proxy to
create an outgoing server connection. This is done even if your
connectivity mode is set to offline. This behavior is intentional, and
permits clever scripters to automate periodic dial-ups and forced server
flushes.
On Win95/98/NT, when running the proxy in a window you can press
Ctrl-Break at any time to perform the equivalent of a HUP+ALRM signal on
UNIX. To actually close the proxy, press Ctrl-C or close window.
On OS/2 you can press Ctrl-C to force a reload of the ini file and create an outgoing server connection. Ctrl-Break is used to close the proxy.
The personal proxy can run on successfully on a Windows 95/98/ME workstation, however it is discouraged that this be done on a machine that is being heavily used as a normal user workstation, due to the frequent crashes and relative instability of Win95/98/ME when it is actively being used. If you really need to run a proxy on a Windows machine, it is recommended that you use an NT machine, if possible.
On Windows NT, the proxy can be run either as a foreground console application or installed as a service and run transparently in the background, unaffected by user logins. (See the "command line options" section for instruction on service installation and removal).
Under Windows 95/98/ME, the proxy can only be run as a foreground console application. There are no plans to support running the proxy as a "hidden" or "service" application in this environment.
Please be aware that if you are running the proxy as a foreground console (and not as an NT Service), you should avoid simply closing the console window directly. Instead, when you want to shut down the proxy, you need to focus the window and press Ctrl-C to initiate a shutdown. Failure to do this will cause the proxy to not have an opportunity to shutdown nicely, possibly corrupting your buffers or causing some blocks to be lost.
Notice that the personal proxy requires Winsock 2 services to be available. Most original distributions of Windows 95 (but not Win98 or WinNT4) come with only Winsock 1.1, so you must install the update from Microsoft. You can download this update from Microsoft's website.
The personal proxy allows several command line options that tell it to enter one of several exclusive and session-lasting modes of operation.
On Windows NT only, you can install the proxy as a service by first running it with the "-install" option to register it as a service. You can then start and stop the proxy from the standard Windows NT services Control Panel. You can use the "-uninstall" option to remove it from the services registry.
Previously a detached mode option existed in the ini file to allow the proxy to be started as a daemon-like service on your UNIX machine. This has now been made available only as a command-line option, and must be invoked by starting the proxy with "-detach" on the command line.
The personal proxy requires Solaris 2.6 or greater to run.
Solaris 2.6 requires Sun Patch ID #105591 which is available from
http://sunsolve.sun.com/ in order to run the
personal proxy. Other Solaris versions may require a similar patch. If
you encounter the error ld.so.1: proxyper: fatal: libCrun.so.1: open failed: No such file or directory, you must install the patch.
