PROGRAM:

NAME


pr3287 - IBM host printing tool

SYNOPSIS


pr3287 [ options ] [ L: ] [[ LUname [, LUname ...]@] hostname [: port ]]

DESCRIPTION


pr3287 opens a telnet connection to an IBM host, and emulates an IBM 3287 printer. It
implements RFCs 2355 (TN3270E), 1576 (TN3270) and 1646 (LU name selection).

If the hostname is prefixed with L:, the connection will be made through an SSL tunnel.
pr3287 also supports TELNET START-TLS option negotiation without any need for command-line
options.

A specific LU name to use may be specified by prepending it to the hostname with an `@'.
Multiple LU names to try can be separated by commas. An empty LU can be placed in the
list with an extra comma.

The port to connect to defaults to telnet. This can be overridden by appending a port to
the hostname with a colon `:'.

OPTIONS


pr3287 understands the following options:

-accepthostname spec
Specifies a particular hostname to accept when validating the name presented in the
host's SSL certificate, instead of comparing to the name or address used to make
the connection. spec can either be any, which disables name validation,
DNS:hostname, which matches a particular DNS hostname, or IP:address, which matches
a particular numeric IPv4 or IPv6 address.

-assoc LUname
Causes the session to be associated with the specified LUname.

-blanklines
In LU3 formatted mode, print blank lines even if they are all NULLs or control
characters. (This is a violation of the 3270 printer protocol, but some hosts
require it.)

-cadir directory
Specifies a directory containing CA (root) certificates to use when verifying a
certificate provided by the host.

-cafile filename
Specifies a PEM-format file containing CA (root) certificates to use when verifying
a certificate provided by the host.

-certfile filename
Specifies a file containing a certificate to provide to the host, if requested.
The default file type is PEM.

-certfiletype type
Specifies the type of the certificate file specified by -certfile. Type can be pem
or asn1.

-chainfile filename
Specifies a certificate chain file in PEM format, containing a certificate to
provide to the host if requested, as well as one or more intermediate certificates
and the CA certificate used to sign that certificate. If -chainfile is specified,
it overrides -certfile.

-charset name
Specifies an alternate host code page (input EBCDIC mapping). The default maps the
U.S. English (037) code page to the current locale character encoding. pr3287
generally supports the same host character sets as x3270.

-command command
Specifies the command to run for each print job. The default is lpr.

-crlf Causes newline characters in the output to be expanded to carriage-return/linefeed
sequences.

-crthru
In unformatted 3270 mode, causes EBCDIC CR orders to be passed to directly to the
printer as ASCII CR characters, and the output buffer to be flushed, instead of
being specially interpreted by pr3287.

By default, EBCDIC CRs cause the (virtual) print head to return to column 0, so
that subsequent text overwrites what is already in the buffer, and the buffer is
flushed only when an EBCDIC NL or EM order is received.

-daemon
Causes pr3287 to become a daemon (background) process.

-eojtimeout seconds
Causes pr3287 to complete the print job after seconds seconds of inactivity.

-emflush
Causes pr3287 to flush any pending printer output whenever an EM (End of Medium)
order arrives in unformatted 3270 mode. This can help preserve multi-page output
with hosts that do not clear the 3270 buffer between pages. (Note: This option is
defined for historical purposes only; -emflush is now the default.)

-noemflush
Causes pr3287 not to flush any pending printer output when an EM (End of Medium)
order arrives in unformatted 3270 mode.

-ignoreeoj
Ignore TN3270E PRINT-EOJ commands, relying on UNBIND commands to indicate the ends
of print jobs.

-ffeoj Causes pr3287 to add a FF (formfeed) at the end of each print job.

-ffskip
Causes pr3287 to ignore a FF (formfeed) order if it occurs at the top of a page.

-ffthru
In SCS mode, causes pr3287 to pass FF (formfeed) orders through to the printer as
ASCII formfeed characters, rather than simulating them based on the values of the
MPL (maximum presentation line) and TM (top margin) parameters.

-keyfile filename
Specifies a file containing the private key for the certificate file (specified via
-certfile or -chainfile). The default file type is PEM.

-keyfiletype type
Specifies the type of the private key file specified by -keyfile. Type can be pem
or asn1.

-keypasswd type:value
Specifies the password for the private key file, if it is encrypted. The argument
can be file:filename, specifying that the password is in a file, or string:string,
specifying the password on the command-line directly.

-proxy type:host[:port]
Causes pr3287 to connect via the specified proxy, instead of using a direct
connection. The host can be an IP address or hostname. The optional port can be a
number or a service name. For a list of supported proxy types, see PROXY below.

-reconnect
Causes pr3287 to reconnect to the host, whenever the connection is broken. There
is a 5-second delay between reconnect attempts, to reduce network thrashing for
down or misconfigured hosts.

-selfsignedok
Allow self-signed host certificates.

-skipcc
For unformatted writes, skip ASA carriage control characters (e.g., blank for
single-space, 0 for double-space, 1 for formfeed, etc.) in the first position of
each line of host output.

-trace Turns on data stream tracing. Trace information is usually saved in the file
/tmp/x3trc.pid.

-tracedir dir
Specifies the directory to save trace files in, instead of /tmp.

-trnpre file
Specifies a file containing data that will be sent to the printer before each print
job. The file contents are treated as transparent data, i.e., they are not
translated in any way.

-trnpost file
Specifies a file containing data that will be sent to the printer after each print
job. The file contents are treated as transparent data, i.e., they are not
translated in any way.

-v Display build and version information and exit.

-verifycert
Verify the host certificate for tunneled SSL and negotiated SSL/TLS connections.

-xtable file
Specifies a file containing transparent data translations. The file specifies
EBCDIC characters that will be translated into transparent ASCII data (data that
will not be further translated and will not count as taking up column(s) on the
print line). Any printable ECBDIC code can be translated to zero or more ASCII
characters.

The table consists of lines that look like:
ebcdic ebcdic-code ascii ascii-code...

The ebcdic-code can be specified in hexadecimal X'nn' notation or as numbers in
decimal, octal (with a leading 0) or hexadecimal (with a leading 0x). The ascii-
codes can be specified as numbers in decimal, octal or hexadecimal, control codes
such as ^X, symbolic control codes such as CR or Escape, or as double-quoted
strings, following the full C-language conventions, such as \r for a carriage
return. Comments begin with #, ! or //.

Here are some examples of translations.
# Expand EBCDIC D to an escape sequence.
ebcdic X'C4' ascii Esc "]1,3" 0x6d
# Delete EBCDIC B's
ebcdic X'C2' ascii

The full list of symbolic control codes is: BS CR BEL ESC ESCAPE FF HT LF NL NUL
SPACE TAB VT.

SIGNALS


SIGINT, SIGHUP and SIGTERM cause the current print job to be flushed (any pending data to
be printed) and pr3287 to exit.

SIGUSR1 causes the current print job to be flushed without otherwise affecting the pr3287
process.

PROXY


The -proxy option causes pr3287 to use a proxy server to connect to the host. The syntax
of the option is:
type:host[:port]

The supported values for type are:

Proxy Type Protocol Default Port
───────────────────────────────────────────────────
http RFC 2817 HTTP tunnel 3128
(squid)
passthru Sun in.telnet-gw none
socks4 SOCKS version 4 1080
socks5 SOCKS version 5 (RFC 1080
1928)
telnet No protocol (just send none
connect host port)

The special types socks4a and socks5d can also be used to force the proxy server to do the
hostname resolution for the SOCKS protocol.
