.SH EXAMPLES
.LP
The recommended way to use a proxy connection command is to configure the
\fBProxyCommand\fR in \fBssh_config\fR(4) (see Example 1 and Example 2).
Example 3 shows how the proxy command can be specified on the command line when
running \fBssh\fR(1).
.LP
\fBExample 1 \fRSetting the proxy from the environment
.sp
.LP
The following example uses \fBssh-http-proxy-connect\fR in \fBssh_config\fR(4)
when the proxy is set from the environment:

.sp
.in +2
.nf
\fBHost playtime.foo.com
    ProxyCommand /usr/lib/ssh/ssh-http-proxy-connect \e
        playtime.foo.com 22\fR
.fi
.in -2
.sp

.LP
\fBExample 2 \fROverriding proxy environment variables
.sp
.LP
The following example uses \fBssh-http-proxy-connect\fR in \fBssh_config\fR(4)
to override (or if not set) proxy environment variables:

.sp
.in +2
.nf
\fBHost playtime.foo.com
    ProxyCommand /usr/lib/ssh/ssh-http-proxy-connect -h webcache \e
        -p 8080 playtime.foo.com 22\fR
.fi
.in -2
.sp

.LP
\fBExample 3 \fRUsing the command line
.sp
.LP
The following example uses \fBssh-http-proxy-connect\fR from the \fBssh\fR(1)
command line:

.sp
.in +2
.nf
example$ \fBssh -o'ProxyCommand="/usr/lib/ssh/ssh-http-proxy-connect \e
    -h webcache -p 8080 playtime.foo.com 22"' playtime.foo.com\fR
.fi
.in -2
.sp
