 .IP "\fB\-p\fR \fIproto_port_spec\fR"

 specifies protocol and ports to connect to.  If not given, \fBproxycheck\fR

 will try it's built-in default list.  This option may be specified more

 than once.   See below for \fIproto_port_spec\fR.  If \fIproto_port_spec\fR

 is specified for a single host to check, it applies to that host only,

 and no protocols/ports in default list will be checked for that host.

 .IP "\fB\-m\fR \fImaxconn\fR"

 Do not attempt to make more than \fImaxconn\fR parallel connections.

 By default, maximum number of parallel connections limited by the

 operating system and on most systems it is around 1000.

-

 .IP "\fB\-M\fR \fImaxhconn\fR"

 Do not make more than \fImaxhconn\fR parallel connections to the

 same host (default is unlimited).  This may be useful for overloaded

 proxies which can't handle many parallel connections using different

 ports/protocols, but may significantly slow down the whole process.

-

 .IP \fB\-s\fR

 when an open proxy is found on a given IP, stop probing for other

 ports/protocols for this IP.  Best used when many IPs are tested,

 and/or with \fB\-M\fR option.  This is because currently, \fBproxycheck\fR

 will not make any \fInew\fR connections to such host, but will wait

 for already active connections to complete.

+.SH EXAMPLES

+In the simplest case, specify:

+

+.nf

+  proxycheck -vv -ddsthost:dstport -c chat::"waitstr" \fIlist-of-IPs\fR

+.fi

+

+where

+\fBdsthost\fR is the host and \fBdstport\fR is the port number of the

+destination system, and \fBwaitstr\fR is a string to look for from the remote

+system. If you decide to connect to your own mailserver (which is quite

+logical, since most proxy abuse nowadays is to send spam to your mailserver),

+connect to it first using telnet and see which SMTP greeting string it prints

+out upon connection, and use this string as \fBwaitstr\fR.  For example, if

+your mailserver is \fImail.example.com\fR, the following may apply:

+

+.nf

+  $ \fBtelnet mail.example.com 25\fR

+  Telnet: trying 127.0.0.1... connected.

+  250 mail.example.com ESMTP welcome

+  \fBQUIT\fR

+.fi

+

+In this case, \fBproxycheck\fR's command line may look as follows:

+

+.nf

+  proxycheck -vv -d mail.example.com:25 \\

+   -c chat::"250 mail.example.com ESMTP welcome" \fIlist-of-IPs\fR

+.fi

+

+Another usage scenario is to automatically submit all open proxies to

+DSBL.org-style blocklists.  For this, specify \fB-c dsbl\fR and set up

+environment variables for dsbl client.  The variables \fBDSBL_USER\fR and

+\fBDSBL_PASS\fR are required for non-anonymous DSBL submissions, for anonymous

+submissions to the \fIunconfirmed.dsbl.org\fR defaults are sufficient. To

+submit a proxy to DSBL.org, set destination to the mail exchanger of

+\fIlistme.dsbl.org\fR domain, currently \fImx.listme.dsbl.org\fR.  For example:

+

+.nf

+  DSBL_USER=username DSBL_PASS=password ./proxycheck -vv \\

+   -dmx.listme.dsbl.org:25 -cdsbl \fIproxyhost\fR

+.fi
