.SH NAME
.B 3proxy.cfg
\- 3proxy configuration file
.SH DESCRIPTION
 Common structure:
.br
 Configuration file is a text file 3proxy reads configuration from. Each line
of the file is a command executed immediately, as it was given from
console. Sequence of commands is important. Configuration file as actually a
script for 3proxy executable.
Each line of the file is treated as a blank (space or tab) separated
command line. Additional space characters are ignored. 
Think about 3proxy as "application level router" with console interface.

.br
 Comments:
.br
 Any string beginning with space character or \'#\' character is comment. It\'s
ignored. <LF>s are ignored. <CR> is end of command.

.br
 Quotation:
.br
 Quotation character is " (double quote). Quotation must be used to quote
spaces or another special characters. To use quotation character inside
quotation character must be dubbed (BASIC convention). For example to use
HELLO "WORLD" as an argument you should use it as "HELLO ""WORLD"""\.
Good practice is to quote any argument you use.

.br
 File inclusion:
.br
 You can include file by using $FILENAME macro (replace FILENAME with a path
to file, for example $/usr/local/etc/3proxy/conf.incl or 
 $"c:\\Program Files\\3proxy\\include.cfg" Quotation is
required in last example because path contains space character. 
For included file <CR> (end of line characters) is treated as space character
(arguments delimiter instead of end of command delimiter). 
Thus, include files are only useful to store long signle-line commands
(like userlist, network lists, etc).
To use dollar sign somewhere in argument it must be quoted. 
Recursion is not allowed.

.br
 Next commands start gateway services:

.br
.B -n
disable NTLM authentication (required if passwords are stored in Unix crypt format.
.br
.B -n1
enable NTLMv1 authentication.
.br
.B -s
(for admin) - secure, allow only secure operations (currently only traffic counters
view without ability to reset).
.br
(for dnspr) - simple, do not use 'resolver' and 3proxy cache, always use external DNS server.
.br
(for udppm) - singlepacket, expect only one packet from both client and server
.br
.B -u
Never ask for username/password
.br
.B -u2
(socks) require username/password in authentication methods
.br
.B -a
(for proxy) - anonymous proxy (no information about client reported)
.br
.B -a1
(for proxy) - anonymous proxy (random client information reported)
.br
.B -a2
(for proxy) - generate Via: and X-Forwared-For: instead of Forwarded:
.br
.B -6
Only resolve IPv6 addresses. IPv4 addresses are packed in IPv6 in IPV6_V6ONLY compatible way.
.br
.B -4
Only resolve IPv4 addresses
.br
.B -46
Resolve IPv6 addresses if IPv4 address is not resolvable
.br
.B -64
Resolve IPv4 addresses if IPv6 address is not resolvable
.br
.B -RHOST:port
listen on given local HOST:port for incoming connections instead of making remote outgoing connection. Can be used with another 3proxy service running -r option for connect back functionality. Most commonly used with tcppm. HOST can be given as IP or hostname, useful in case of dynamic DNS.
.br
.B -rHOST:port
connect to given remote HOST:port instead of listening local connection on -p or default port. Can be used with another 3proxy service running -R option for connect back functionality. Most commonly used with proxy or socks. HOST can be given as IP or hostname, useful in case of dynamic DNS.
.br
.B -ocOPTIONS, -osOPTIONS, -olOPTIONS
options for client (oc), server (os) or listening (ol) socket. Options like TCP_CORK, TCP_NODELAY, TCP_DEFER_ACCEPT, TCP_QUICKACK, TCP_TIMESTAMPS, USE_TCP_FASTOPEN, SO_REUSEADDR, SO_REUSEPORT, SO_PORT_SCALABILITY, SO_REUSE_UNICASTPORT, SO_KEEPALIVE, SO_DONTROUTE may be supported depending on OS.
.br
.B -DiINTERFACE, -DeINTERFACE
bind internal interface / external inteface to given INTERFACE (e.g. eth0) if SO_BINDTODEVICE supported by system
.br
 Also, all options mentioned for 
.BR proxy (8)
.BR socks (8)
.BR pop3p (8)
.BR tcppm (8)
.BR udppm (8)
.BR ftppr (8)
 are also supported.
.br
 Portmapping services listen at SRCPORT and connect to DSTADDR:DSTPORT
HTTP and SOCKS proxies are standard. 
.br
 POP3 proxy must be configured as POP3 server and requires username in the form of:
pop3username@pop3server. If POP3 proxy access must be authenticated, you can
specify username as proxy_username:proxy_password:POP3_username@pop3server
.br
 DNS proxy resolves any types of records but only hostnames are cached. It
requires nserver/nscache to be configured. If nserver is configured as TCP,
redirections are applied on connection, so parent proxy may be used to resolve
names to IP.
.br
 FTP proxy can be used as FTP server in any FTP client or configured as FTP
proxy on a client with FTP proxy support. Username format is one of
.br
 FTPuser@FTPServer
.br
 FTPuser:FTPpassword@FTPserver
.br
 proxyuser:proxypassword:FTPuser:FTPpassword@FTPserver
.br
 Please note, if you use FTP client interface for FTP proxy do not add FTPpassword and FTPServer to username, because FTP client does it for you. That is, if you use 3proxy with authentication use proxyuser:proxypassword:FTPuser as FTP username, otherwise do not change original FTP user name

.br
.B include
<path>
.br
 Include config file

.br
.B config
<path>
.br
 Path to configuration file to use on 3proxy restart or to save configuration.

.br
.B writable
.br
 ReOpens configuration file for write access via Web interface,
and re-reads it. Usually should be first command on config file
but in combination with "config" it can be used anywhere to open
alternate config file. Think twice before using it.

.br
.B end
.br
 End of configuration

.br
.B log
[[@|&]logfile] [<LOGTYPE>]
.br
 sets logfile for all gateways
.br
 @ - (for Unix) use syslog, filename is used as ident name
.br
 & - use ODBC, filename consists of comma-delimited datasource,username,password (username and password are optional)
.br
 LOGTYPE is one of:
.br
  M - Monthly
.br
  W - Weekly (starting from Sunday)
.br
  D - Daily
.br
  H - Hourly
.br
 if logfile is not specified logging goes to stdout. You can specify individual logging options for gateway by using
-l option in gateway configuration.
.br
 "log" command supports same format specifications for filename template
as "logformat" (if filename contains '%' sign it's believed to be template).
As with "logformat" filename must begin with 'L' or 'G' to specify Local or
Grinwitch time zone for all time-based format specificators.

.br
.B rotate
<n>
 how many archived log files to keep

.br
.B logformat
<format>
.br
 Format for log record. First symbol in format must be L (local time)
or G (absolute Grinwitch time). 
It can be preceeded with -XXX+Y where XXX is list of characters to be
filtered in user input (any non-printable characters are filtered too
in this case) and Y is replacement character. For example, "-,%+ L" in
the beginning of logformat means comma and percent are replaced
with space and all time based elemnts are in local time zone.
.br
 You can use:

.br
  %y - Year in 2 digit format
.br
  %Y - Year in 4 digit format
.br
  %m - Month number
.br
  %o - Month abbriviature
.br
  %d - Day
.br
  %H - Hour
.br
  %M - Minute
.br
  %S - Second
.br
  %t - Timstamp (in seconds since 01-Jan-1970)
.br
  %. - milliseconds
.br
  %z - timeZone (from Grinvitch)
.br
  %D - request duration (in milliseconds)
.br
  %b - average send rate per request (in Bytes per second) this speed is typically below connection speed shown by download manager.
.br
  %B - average receive rate per request (in Bytes per second) this speed is typically below connection speed shown by download manager.
.br
  %U - Username
.br
  %N - service Name
.br
  %p - service Port
.br
  %E - Error code
.br
  %C - Client IP
.br
  %c - Client port
.br
  %R - Remote IP
.br
  %r - Remote port
.br
  %i - Internal IP used to accept client connection
.br
  %e - External IP used to establish connection
.br
  %Q - Requested IP
.br
  %q - Requested port
.br
  %n - requested hostname
.br
  %I - bytes In
.br
  %O - bytes Out
.br
  %h - Hops (redirections) count
.br
  %T - service specific Text
.br
  %N1-N2T - (N1 and N2 are positive numbers) - log only fields from N1 thorugh N2 of service specific text
.br
 in case of ODBC logging logformat specifies SQL statement, for exmample:
.br
   logformat "-'+_Linsert into log (l_date, l_user, l_service, l_in, l_out, l_descr) values ('%d-%m-%Y %H:%M:%S', '%U', '%N', %I, %O, '%T')"

.br
.B logdump
<in_traffic_limit> <out_traffic_limit>
.br
 Immediately creates additional log records if given amount of incoming/outgoing
traffic is achieved for connection, without waiting for connection to finish.
It may be useful to prevent information about long-lasting downloads on server
shutdown.

.br
.B archiver
<ext> <commandline>
.br
 Archiver to use for log files. <ext> is file extension produced by
archiver. Filename will be last argument to archiver, optionally you
can use %A as produced archive name and %F as filename.

.br
.B timeouts
<BYTE_SHORT> <BYTE_LONG> <STRING_SHORT> <STRING_LONG> <CONNECTION_SHORT> <CONNECTION_LONG> <DNS> <CHAIN>
.br
 Sets timeout values
.br
  BYTE_SHORT - short timeout for single byte, is usually used for receiving single byte from stream.
.br
  BYTE_LONG - long timeout for single byte, is usually used for receiving first byte in frame (for example first byte in socks request).
.br
  STRING_SHORT - short timeout, for character string within stream (for example to wait between 2 HTTP headers)
.br
  STRING_LONG - long timeout, for first string in stream (for example to wait for HTTP request).
.br
  CONNECTION_SHORT - inactivity timeout for short connections (HTTP, POP3, etc).
.br
  CONNECTION_LONG - inactivity timeout for long connection (SOCKS, portmappers, etc).
.br
  DNS - timeout for DNS request before requesting next server
.br
  CHAIN - timeout for reading data from chained connection
.br

.br
.B nserver
<ipaddr>[:port][/tcp]
.br
Nameserver to use for name resolutions. If none specified 
or name server fails system routines for name resolution will be
used. It's better to specify nserver because gethostbyname() may
be thread unsafe. Optional port number may be specified.
If optional /tcp is added to IP address, name resolution will be
performed over TCP.

.br
.B nscache
<cachesize>
.B nscache6
<cachesize>
.br
 Cache <cachesize> records for name resolution (nscache for IPv4,
nscache6 for IPv6). Cachesize usually should be large enougth
(for example 65536).

.br
.B nsrecord
<hostname> <hostaddr>
.br
 Adds static record to nscache. nscache must be enabled. If 0.0.0.0
is used as a hostaddr host will never resolve, it can be used to
blacklist something or together with 
.B dialer
command to set up UDL for dialing.

.br
.B fakeresolve
.br
 All names are resolved to 127.0.0.2 address. Usefull if all requests are
redirected to parent proxy with http, socks4+, connect+ or socks5+.

.br
.B dialer
<progname>
.br
 Execute progname if external name can't be resolved.
Hint: if you use nscache, dialer may not work, because names will
be resolved through cache. In this case you can use something like
http://dial.right.now/ from browser to set up connection.


.br
.B internal
<ipaddr>
.br
 sets ip address of internal interface. This IP address will be used
to bind gateways. Alternatively you can use -i option for individual
gateways. Since 0.8 version, IPv6 address may be used.

.br
.B external
<ipaddr>
.br
 sets ip address of external interface. This IP address will be source
address for all connections made by proxy. Alternatively you can use
-e option to specify individual address for gateway. Since 0.8 version
External or -e can be given twice: once with IPv4 and once with IPv6 address.
   
.br
.B maxconn
<number>
.br
 sets maximum number of simulationeous connections to each services
started after this command. Default is 100.

.br
.B service
.br
 (depricated). Indicates 3proxy to behave as Windows 95/98/NT/2000/XP
service, no effect for Unix. Not required for 3proxy 0.6 and above. If
you upgraded from previous version of 3proxy use --remove and --install
to reinstall service.

.br
.B daemon
.br
 Should be specified to close console. Do not use 'daemon' with 'service'.
At least under FreeBSD 'daemon' should preceed any proxy service
and log commands to avoid sockets problem. Always place it in the beginning
of the configuration file.

.br
.B auth
<authtype> [...]
.br
 Type of user authorization. Currently supported:
.br
  none - no authentication or authorization required.
.br
 Note: is auth is none any ip based limitation, redirection, etc will not work. 
This is default authentication type
.br
  iponly - authentication by access control list with username ignored.
 Appropriate for most cases
.br
  useronly - authentication by username without checking for any password with
authorization by ACLs. Useful for e.g. SOCKSv4 proxy and icqpr (icqpr set UIN /
AOL screen name as a username)
.br
  dnsname - authentication by DNS hostnname with authorization by ACLs.
DNS hostname is resolved via PTR (reverse) record and validated (resolved
name must resolve to same IP address). It's recommended to use authcache by
ip for this authentication.
NB: there is no any password check, name may be spoofed.
.br
  strong - username/password authentication required. It will work with
SOCKSv5, FTP, POP3 and HTTP proxy. 
.br
  cache - cached authentication, may be used with 'authcache'.
.br
 Plugins may add additional authentication types.
.br

 It's possible to use few authentication types in the same commands. E.g.
.br
auth iponly strong
.br
 In this case 'strong' authentication will be used only in case resource
access can not be performed with 'iponly' authentication, that is username is
required in ACL. It's usefull to protect access to some resources with
password allowing passwordless access to another resources, or to use
IP-based authentication for dedicated laptops and request username/password for
shared ones.

.br
.B authcache
<cachtype> <cachtime>
.br
 Cache authentication information to given amount of time (cachetime) in seconds.
Cahtype is one of:
.br
  ip - after successful authentication all connections during caching time
from same IP are assigned to the same user, username is not requested.
.br
  ip,user username is requested and all connections from the same IP are
assigned to the same user without actual authentication.
.br
  user - same as above, but IP is not checked. 
.br
  user,password - both username and password are checked against cached ones.
.br
Use auth type 'cache' for cached authentication

.br
.B allow
<userlist> <sourcelist> <targetlist> <targetportlist> <operationlist>
<weekdayslist> <timeperiodslist>
.br
.B deny
<userlist> <sourcelist> <targetlist> <targetportlist> <operationlist>
<weekdayslist> <timeperiodslist>
.br
 Access control entries. All lists are comma-separated, no spaces are
allowed. Usernames are case sensitive (if used with authtype nbname
username must be in uppercase). Source and target lists may contain
IP addresses (W.X.Y.Z), ranges A.B.C.D - W.X.Y.Z (since 0.8) or CIDRs
(W.X.Y.Z/L). Since 0.6, targetlist may also contain host names,
instead of addresses. It's possible to use wildmask in
the begginning and in the the end of hostname, e.g. *badsite.com or
*badcontent*. Hostname is only checked if hostname presents in request.
Targetportlist may contain ports (X) or port ranges lists (X-Y). For any field
* sign means "ANY" If access list is empty it's assumed to be
.br
 allow *
.br
 If access list is not empty last item in access list is assumed to be
.br
 deny *
.br
 You may want explicitly add "deny *" to the end of access list to prevent
HTTP proxy from requesting user's password.
Access lists are checked after user have requested any resource.
If you want 3proxy to reject connections from specific addresses
immediately without any conditions you should either bind proxy
to appropriate interface only or to use ip filters.
.br

Operation is one of:
.br
  CONNECT - establish outgoing TCP connection
.br
  BIND - bind TCP port for listening
.br
  UDPASSOC - make UDP association
.br
  ICMPASSOC - make ICMP association (for future use)
.br
  HTTP_GET - HTTP GET request
.br
  HTTP_PUT - HTTP PUT request
.br
  HTTP_POST - HTTP POST request
.br
  HTTP_HEAD - HTTP HEAD request
.br
  HTTP_CONNECT - HTTP CONNECT request
.br
  HTTP_OTHER - over HTTP request
.br
  HTTP - matches any HTTP request except HTTP_CONNECT
.br
  HTTPS - same as HTTP_CONNECT
.br
  FTP_GET - FTP get request
.br
  FTP_PUT - FTP put request
.br
  FTP_LIST - FTP list request
.br
  FTP_DATA - FTP data connection. Note: FTP_DATA requires access to dynamic
non-ptivileged (1024-65535) ports on remote side.
.br
  FTP - matches any FTP/FTP Data request
.br
  ADMIN - access to administration interface
.br
 Weeksdays are week days numbers or periods, 0 or 7 means Sunday, 1 is Monday, 1-5 means Monday through Friday. Timeperiodlists is a list of time
periods in HH:MM:SS-HH:MM:SS format. For example, 00:00:00-08:00:00,17:00:00-24:00:00 lists non-working hours.
	
.br
.B parent
<weight> <type> <ip> <port> <username> <password>
.br
 this command must follow "allow" rule. It extends last allow rule to
build proxy chain. Proxies may be grouped. Proxy inside the
group is selected randomly. If few groups are specified one proxy
is randomly picked from each group and chain of proxies is created
(that is second proxy connected through first one and so on).
Weight is used to group proxies. Weigt is a number between 1 and 1000.
Weights are summed and proxies are grouped together untill weight of
group is 1000. That is:
.br
 allow *
.br
 parent 500 socks5 192.168.10.1 1080
.br
 parent 500 connect 192.168.10.1 3128
.br
 makes 3proxy to randomly choose between 2 proxies for all outgoing
connections. These 2 proxies form 1 group (summarized weight is 1000).
.br
 allow * * * 80
.br
 parent 1000 socks5 192.168.10.1 1080
.br
 parent 1000 connect 192.168.20.1 3128
.br
 parent 300 socks4 192.168.30.1 1080
.br
 parent 700 socks5 192.168.40.1 1080
.br
 creates chain of 3 proxies: 192.168.10.1, 192.168.20.1 and third
is (192.168.30.1 with probability of 0.3 or 192.168.40.1
with probability of 0.7) for outgoing web connections.

.br
 type is one of:
.br
  tcp - simply redirect connection. TCP is always last in chain.
.br
  http - redirect to HTTP proxy. HTTP is always last chain.
.br
  pop3 - redirect to POP3 proxy (only local redirection is supported, can not be
used for chaining)
.br
  ftp - redirect to FTP proxy (only local redirection is supported, can not be
used for chaining)
.br
  connect - parent is HTTP CONNECT method proxy
.br
  connect+ - parent is HTTP CONNECT proxy with name resolution
.br
  socks4 - parent is SOCKSv4 proxy
.br
  socks4+ - parent is SOCKSv4 proxy with name resolution (SOCKSv4a)
.br
  socks5 - parent is SOCKSv5 proxy
.br
  socks5+ - parent is SOCKSv5 proxy with name resolution
.br
  socks4b - parent is SOCKS4b (broken SOCKSv4 implementation with shortened
server reply. I never saw this kind ofservers byt they say there are).
Normally you should not use this option. Do not mess this option with
SOCKSv4a (socks4+).
.br
  socks5b - parent is SOCKS5b (broken SOCKSv5 implementation with shortened
server reply. I think you will never find it useful). Never use this option
unless you know exactly you need it.
.br
  admin - redirect request to local 'admin' service (with -s parameter).
.br
 Use "+" proxy only with "fakeresolve" option
.br

 IP and port are ip addres and port of parent proxy server.
If IP is zero, ip is taken from original request, only port is changed.
If port is zero, it's taken from original request, only IP is changed.
If both IP and port are zero - it's a special case of local redirection,
it works only with
.B socks
proxy. In case of local redirection request is redirected to different service, 
.B ftp
locally redirects to
.B ftppr
.B pop3
locally redirects to
.B pop3p
.B http
locally redurects to
.B proxy
.B admin
locally redirects to admin -s service.
.br

 Main purpose of local redirections is to have requested resource
(URL or POP3 username) logged and protocol-specific filters to be applied.
In case of local redirection ACLs are revied twice: first, by SOCKS proxy up to
'parent' command and then with gateway service connection is
redirected (HTTP, FTP or POP3) after 'parent' command. It means,
additional 'allow' command is required for redirected requests, for
example:
.br
 allow * * * 80
.br
 parent 1000 http 0.0.0.0 0
.br
 allow * * * 80 HTTP_GET,HTTP_POST
.br
 socks
.br
 redirects all SOCKS requests with target port 80 to local HTTP proxy,
local HTTP proxy parses requests and allows only GET and POST requests.
.br
 parent 1000 http 1.2.3.4 0
.br
 Changes external address for given connection to 1.2.3.4
(an equivalent to -e1.2.3.4)
.br
 Optional username and password are used to authenticate on parent
proxy. Username of '*' means username must be supplied by user.


.br
.B nolog
<n>
.br
 extends last allow or deny command to prevent logging, e.g.
.br
allow * * 192.168.1.1
.br
nolog


.br
.B weight
<n>
.br
 extends last allow or deny command to set weight for this request
.br
 allow * * 192.168.1.1
.br
 weight 100
.br
 Weight may be used for different purposes.


.br
.B force
.br
.B noforce
.br
 If force is specified for service, configuration reload will require all current
sessions of this service to be re-authenticated. If ACL is changed or user account
is removed, old connections which do not match current are closed.
 noforce allows to keep previously authenticated connections.

.br
.B bandlimin
<rate> <userlist> <sourcelist> <targetlist> <targetportlist> <operationlist>
.br
.B nobandlimin
<userlist> <sourcelist> <targetlist> <targetportlist> <operationlist>
.br
.B bandlimout
<rate> <userlist> <sourcelist> <targetlist> <targetportlist> <operationlist>
.br
.B nobandlimout
<userlist> <sourcelist> <targetlist> <targetportlist> <operationlist>
.br
 bandlim sets bandwith limitation filter to <rate> bps (bits per second)
(if you want to specife bytes per second - multiply your value to 8).
bandlim rules act in a same manner as allow/deny rules except
one thing: bandwidth limiting is applied to all services, not to some
specific service. 
bandlimin and nobandlimin applies to incoming traffic
bandlimout and nobandlimout applies to outgoing traffic
If tou want to ratelimit your clients with ip's 192.168.10.16/30 (4
addresses) to 57600 bps you have to specify 4 rules like
.br
 bandlimin 57600 * 192.168.10.16
.br
 bandlimin 57600 * 192.168.10.17
.br
 bandlimin 57600 * 192.168.10.18
.br
 bandlimin 57600 * 192.168.10.19
.br
 and every of you clients will have 56K channel. If you specify
.br
 bandlimin 57600 * 192.168.10.16/30
.br
 you will have 56K channel shared between all clients.
if you want, for example, to limit all speed ecept access to POP3 you can use
.br
 nobandlimin * * * 110
.br
 before the rest of bandlim rules.

.br
.B counter
<filename> <reporttype> <repotname>
.br
.B countin
<number> <type> <limit> <userlist> <sourcelist> <targetlist> <targetportlist> <operationlist>
.br
.B nocountin
<userlist> <sourcelist> <targetlist> <targetportlist> <operationlist>
.br
.B countout
<number> <type> <limit> <userlist> <sourcelist> <targetlist> <targetportlist> <operationlist>
.br
.B nocountout
<userlist> <sourcelist> <targetlist> <targetportlist> <operationlist>
.br

 counter, countin, nocountin, countout, noucountout  commands are 
used to set traffic limit
in MB for period of time (day, week or month). Filename is a path
to a special file where traffic information is permanently stored.
number is sequential number of record in this file. If number is 0
no traffic information  on this counter is saved in file (that is
if proxy restarted all information is loosed) overwise it should be
unique sequential number.
Type specifies a type of counter. Type is one of:
.br
 H - counter is resetted hourly
.br
 D - counter is resetted daily
.br
 W - counter is resetted weekly
.br
 M - counter is resetted monthely
.br
 reporttype/repotname may be used to generate traffic reports.
Reporttype is one of D,W,M,H(hourly) and repotname specifies filename
template for reports. Report is text file with counter values in
format:
.br
 <COUNTERNUMBER> <TRAF>
.br
 The rest of parameters is identical to bandlim/nobandlim.

.br
.B users
username[:pwtype:password] ...
.br
 pwtype is one of:
.br
  none (empty) - use system authentication
.br
  CL - password is cleartext
.br
  CR - password is crypt-style password
.br
  NT - password is NT password (in hex)
.br
 example:
.br
 users test1:CL:password1 "test2:CR:$1$lFDGlder$pLRb4cU2D7GAT58YQvY49."
.br
 users test3:NT:BD7DFBF29A93F93C63CB84790DA00E63
.br
 Note: double quotes are requiered because password contains $ sign.	

.br
.B flush
.br
 empty active access list. Access list must be flushed avery time you creating
new access list for new service. For example:
.br
 allow *
.br
 pop3p
.br
 flush
.br
 allow * 192.168.1.0/24
.br
 socks
.br
 sets different ACLs for
.B pop3p
and
.B socks

.br
.B system
<command>
.br
 execute system command

.br
.B pidfile
<filename>
.br
 write pid of current process to file. It can be used to manipulate
3proxy with signals under Unix. Currently next signals are available:

.br
.B monitor
<filename>
.br
 If file monitored changes in modification time or size, 3proxy reloads
configuration within one minute. Any number of files may be monitored.

.br
.B setuid
<uid>
.br
 calls setuid(uid), uid must be numeric. Unix only. Warning: under some Linux
kernels setuid() works onle for current thread. It makes it impossible to suid
for all threads.

.br
.B setgid
<gid>
.br
 calls setgid(gid), gid must be numeric. Unix only.

.br
.B chroot
<path>
.br
 calls chroot(path). Unix only.

.br
.B stacksize
<value_to_add_to_default_stack_size>
.br
 Change default size for threads stack. May be required in some situation,
 e.g. with non-default plugins, on on some platforms (some FreeBSD version
 may require adjusting stack size due to invalid defined value in system
 header files, this value is also oftent reqruied to be changed for ODBC and
 PAM support on Linux. If you experience 3proxy
 crash on request processing, try to set some positive value. You may start with
 stacksize 65536 
 and then find the minimal value for service to work. If you experience
 memory shortage, you can try to experiment with negative values.
.SH PLUGINS

.br
.B plugin
<path_to_shared_library> <function_to_call> [<arg1> ...]
.br
 Loads specified library and calls given export function with given arguments,
as 
.br
 int functions_to_call(struct pluginlink * pl, int argc, char * argv[]);
.br
 function_to_call must return 0 in case of success, value > 0 to indicate error.

.br
.B filtermaxsize
<max_size_of_data_to_filter>
.br
 If Content-length (or another data length) is greater than given value, no
data filtering will be performed thorugh filtering plugins to avoid data
corruption and/or Content-Length chaging. Default is 1MB (1048576).
