DESCRIPTION

15       s3270 opens a telnet connection to an IBM host, then allows a script to
16       control the host login session.  It is derived from x3270(1), an X-win‐
17       dows  IBM  3270  emulator.   It  implements  RFCs  2355 (TN3270E), 1576
18       (TN3270) and 1646 (LU  name  selection),  and  supports  IND$FILE  file
19       transfer.  The full syntax for host is:
20              [prefix:]...[LUname@]hostname[:port][=accept]
21
22       Prepending  a  P: onto hostname causes the connection to go through the
23       telnet-passthru service rather than directly to the host.  See PASSTHRU
24       below.
25
26       Prepending  an  S:  onto  hostname  removes  the "extended data stream"
27       option reported to the host.  See -tn below for further information.
28
29       Prepending an N: onto hostname turns off TN3270E support for  the  ses‐
30       sion.
31
32       Prepending  an L: onto hostname causes s3270 to first create an SSL/TLS
33       tunnel to the host, and then create a TN3270 session inside the tunnel.
34       (This  function  is supported only if s3270 was built with SSL/TLS sup‐
35       port).  Note that TLS-encrypted sessions  using  the  TELNET  START-TLS
36       option  are  negotiated with the host automatically; for these sessions
37       the L: prefix should not be used.
38
39       Prepending a Y: onto hostname causes s3270 to skip validation  of  host
40       SSL/TLS  certificates.   This overrides any other configuration or com‐
41       mand-line options.
42
43       Prepending an A: onto  hostname  is  equivalent  to  setting  the  -nvt
44       option; it forces an NVT-mode session instead of a 3270-mode session.
45
46       A specific Logical Unit (LU) name to use may be specified by prepending
47       it to the hostname with an `@'.  Multiple LU names to try can be  sepa‐
48       rated  by  commas.  An empty LU can be placed in the list with an extra
49       comma.  (Note that the LU name is used for different purposes  by  dif‐
50       ferent  kinds of hosts.  For example, CICS uses the LU name as the Ter‐
51       minal ID.)
52
53       The hostname may optionally be placed inside square-bracket  characters
54       `['  and  `]'.  This will prevent any colon `:' characters in the host‐
55       name from being interpreted as indicating option prefixes or port  num‐
56       bers.  This allows numeric IPv6 addresses to be used as hostnames.
57
58       On  systems  that support the forkpty library call, the hostname may be
59       replaced with -e and a command string.  This will cause s3270  to  con‐
60       nect to a local child process, such as a shell.
61
62       The port to connect to defaults to telnet.  This can be overridden with
63       the -port option, or by appending a port to the hostname with  a  colon
64       `:'.   (For  compatability  with  previous  versions  of s3270 and with
65       tn3270(1), the port may also be specified as a second,  separate  argu‐
66       ment.)
67
68       An  optional  accept  name  (a hostname to accept in the host's SSL/TLS
69       certificate) may be specified by appending it to the hostname  with  an
70       equals  sign  (`=').   The  accept  name can also be specified with the
71       -accepthostname option.
72
73

OPTIONS

75        s3270 understands the following options:
76
77       -accepthostname name
78              Specifies a particular hostname to accept  when  validating  the
79              name presented in the server SSL certificate, instead of compar‐
80              ing to the name used to make the connection.
81
82       -cadir directory
83              Specifies a directory containing CA (root) certificates  to  use
84              when  verifying  a  certificate  provided  by the host. (OpenSSL
85              only)
86
87       -cafile filename
88              Specifies a PEM-format file containing CA (root) certificates to
89              use  when verifying a certificate provided by the host. (OpenSSL
90              only)
91
92       -certfile filename
93              Specifies a file containing a client certificate to  provide  to
94              the host.  The default file type is PEM.
95
96       -clientcert name
97              Specifies  the  name  of  a client certificate to provide to the
98              host.  (MacOS only)
99
100       -certfiletype type
101              Specifies the type of the certificate file specified  by  -cert‐
102              file.  Type can be pem or asn1. (OpenSSL only)
103
104       -chainfile filename
105              Specifies  a  certificate chain file in PEM format, containing a
106              certificate to provide to the host,  as  well  as  one  or  more
107              intermediate  certificates  and  the CA certificate used to sign
108              that certificate.  If  -chainfile  is  specified,  it  overrides
109              -certfile. (OpenSSL only)
110
111       -charset name
112              Specifies an EBCDIC host character set.
113
114       -clear toggle
115              Sets the initial value of toggle to false.
116
117       -connecttimeout seconds
118              Specifies the time that s3270 will wait for a host connection to
119              complete.
120
121       -devname name
122              Specifies a device name (workstation ID) for RFC 4777 support.
123
124       -httpd [addr:]port
125              Specifies a port and optional address to listen on for HTTP con‐
126              nections.  Addr can be specified as `*' to indicate 0.0.0.0; the
127              default is 127.0.0.1. IPv6 numeric addresses must  be  specified
128              inside  of square brackets, e.g., [::1]:4080 to specify the IPv6
129              loopback address and TCP port 4080.
130
131              Note that this option is mutually-exclusive with the -scriptport
132              option and disables reading commands from standard input.
133
134       -keyfile filename
135              Specifies  a file containing the private key for the certificate
136              file (specified via -certfile or -chainfile).  The default  file
137              type is PEM. (OpenSSL only)
138
139       -keyfiletype type
140              Specifies  the  type  of the private key file specified by -key‐
141              file.  Type can be pem or asn1. (OpenSSL only)
142
143       -keypasswd type:value
144              Specifies the password for the private  key  file  (OpenSSL)  or
145              client  certificate file (MacOS), if it is encrypted.  The argu‐
146              ment can be file:filename, specifying that the password is in  a
147              file,  or string:string, specifying the password on the command-
148              line directly.  If the private key  file  is  encrypted  and  no
149              -keypasswd  option  is  given,  secure  connections  will not be
150              allowed.
151
152       -km name
153              Specifies the local encoding method for multi-byte  text.   name
154              is  an  encoding name recognized by the ICU library.  (Supported
155              only when s3270 is compiled with  DBCS  support,  and  necessary
156              only when s3270 cannot figure it out from the locale.)
157
158       -loginmacro Action(arg...) ...
159              Specifies a macro to run at login time.
160
161       -minversion version
162              The  minimum  required  version  of s3270, e.g., 3.6ga8.  If the
163              running version is less than the specified version,  s3270  will
164              abort.   The  format  of  a version is major.minortypeiteration.
165              type is ignored, and minor and iteration can be omitted.
166
167       -model name
168              The model of 3270 display to be emulated.  The model name is  in
169              two parts, either of which may be omitted:
170
171              The  first part is the base model, which is either 3278 or 3279.
172              3278 specifies a monochrome (green on black) 3270 display;  3279
173              specifies a color 3270 display.
174
175              The  second part is the model number, which specifies the number
176              of rows and columns.  Model 4 is the default.
177
178                            Model Number   Columns   Rows
179                            ──────────────────────────────
180                                 2           80       24
181                                 3           80       32

184
185              Note: Technically, there is no such 3270 display as a 3279-4  or
186              3279-5, but most hosts seem to work with them anyway.
187
188              The default model is 3279-4.
189
190       -noverifycert
191              For SSL/TLS connections, do not verify the host certificate.
192
193       -nvt   Start  in NVT mode instead of waiting for the host to send data,
194              and make the default terminal type xterm.
195
196       -oversize colsxrows
197              Makes the screen larger than the default for  the  chosen  model
198              number.   This  option  has  effect  only  in  combination  with
199              extended data stream support (controlled by the "s3270.extended"
200              resource),  and  only  if  the  host  supports  the  Query Reply
201              structured field.  The  number  of  columns  multiplied  by  the
202              number  of  rows  must not exceed 16383 (3fff hex), the limit of
203              14-bit 3270 buffer addressing.
204
205       -port n
206              Specifies a different TCP port to connect to.  n can be  a  name
207              from  /etc/services  like  telnet,  or  a  number.   This option
208              changes the default port number used for all connections.   (The
209              positional parameter affects only the initial connection.)
210
211       -proxy type:host[:port]
212              Causes  s3270  to  connect  via  the specified proxy, instead of
213              using a direct connection.  The host can be  an  IP  address  or
214              hostname.   The optional port can be a number or a service name.
215              For a list of supported proxy types, see PROXY below.
216
217       -scriptport [addr:]port
218              Specifies a port and optional address to listen on for scripting
219              connections.   Addr can be specified as `*' to indicate 0.0.0.0;
220              the  default  is  127.0.0.1.  IPv6  numeric  addresses  must  be
221              specified inside of square brackets, e.g., [::1]:4081 to specify
222              the IPv6 loopback address and TCP port 4081.
223
224              Note that this option  is  mutually-exclusive  with  the  -httpd
225              option and disables reading commands from standard input.
226
227       -scriptportonce
228              Allows  s3270  to  accept  only one script connection. When that
229              connection is broken, s3270 will exit.
230
231       -set toggle
232              Sets the initial value of toggle to true.
233
234       -socket
235              Causes the emulator to  create  a  Unix-domain  socket  when  it
236              starts,  for  use  by  script  processes to send commands to the
237              emulator.  The socket is named /tmp/x3sck.pid.  The -p option of
238              x3270if causes it to use this socket, instead of pipes specified
239              by environment variables.
240
241       -tn name
242              Specifies the terminal name to be transmitted  over  the  telnet
243              connection.   The default name is IBM-model_name-E, for example,
244              IBM-3278-4-E.
245
246              Some hosts are confused by the -E suffix on the  terminal  name,
247              and  will  ignore  the  extra  screen area on models 3, 4 and 5.
248              Prepending   an   s:   on   the   hostname,   or   setting   the
249              "s3270.extended"  resource  to  "false", removes the -E from the
250              terminal name when connecting to such hosts.
251
252              The  name  can  also  be  specified  with  the  "s3270.termName"
253              resource.
254
255       -trace Turns  on data stream and event tracing at startup.  The default
256              trace file name is /tmp/x3trc.
257
258       -tracefile file
259              Specifies a file to save data stream and event traces into.   If
260              the name starts with `>>', data will be appended to the file.
261
262       -tracefilesize size
263              Places  a  limit on the size of a trace file.  If this option is
264              not specified, or is specified as 0 or none, the trace file size
265              will be unlimited.  The minimum size is 64 Kbytes.  The value of
266              size can have a K or M suffix, indicating kilobytes or megabytes
267              respectively.   When  the  trace file reaches the size limit, it
268              will be renamed with a `-' appended and a new file started.
269
270       -user name
271              Specifies the user name for RFC 4777 support.
272
273       -utf8  Forces the local codeset to be UTF-8,  ignoring  the  locale  or
274              Windows codepage.
275
276       -v     Display the version and build options for s3270 and exit.
277
278       -verifycert
279              For SSL/TLS connections, verify the host certificate, and do not
280              allow the connection to complete unless  it  can  be  validated.
281              (This  is  the default setting.)  This option is overridden by a
282              y: prepended to the hostname when connecting.
283
284       -xrm "s3270.resource: value"
285              Sets the value  of  the  named  resource  to  value.   Resources
286              control  less  common  s3270  options,  and  are  defined  under
287              RESOURCES below.

ACTIONS

291       Here is a  complete  list  of  basic  s3270  actions.   Script-specific
292       actions are described on the x3270-script(1) manual page.  ).PP Actions
293       marked with an asterisk (*) may block, sending data  to  the  host  and
294       possibly waiting for a response.

362
363       Note that certain parameters to s3270 actions (such  as  the  names  of
364       files and keymaps) are subject to substitutions:
365
366       The  character  ~  at  the  beginning  of a string is replaced with the
367       user's home directory.   A  ~  character  followed  by  a  username  is
368       replaced with that user's home directory.
369
370       Environment  variables  are substituted using the Unix shell convention
371       of $name or ${name}.
372
373       Two special pseudo-environment variables are supported. ${TIMESTAMP} is
374       replaced with a microsecond-resolution timestamp; ${UNIQUE} is replaced
375       with a string guaranteed to make a  unique  filename  (the  process  ID
376       optionally  followed  by  a  dash and a string of digits). ${UNIQUE} is
377       used to form trace file names.
378

FILE TRANSFER

380       The Transfer action implements IND$FILE  file  transfer.   This  action
381       requires  that  the  IND$FILE program be installed on the IBM host, and
382       that the 3270 cursor be located in a field that will accept  a  TSO  or
383       VM/CMS command.
384
385       Because  of the complexity and number of options for file transfer, the
386       parameters to the Transfer action take the unique form of option=value,
387       and  can  appear  in any order.  Note that if the value contains spaces
388       (such as a VM/CMS file name), then the entire parameter must be quoted,
389       e.g., "HostFile=xxx foo a".  The options are:
390
391       Option           Required?   Default   Other Values
392       ────────────────────────────────────────────────────────

411       Avblock          Sometimes
412       BufferSize          No       4096
413
414       The option details are as follows.
415
416       Direction
417              send to send a file to the host, receive to receive a file  from
418              the host.
419
420       HostFile
421              The name of the file on the host.
422
423       LocalFile
424              The name of the file on the local workstation.
425
426       Host   The  type  of  host  (which  dictates  the  form of the IND$FILE
427              command): tso (the default), vm or cics.
428
429       Mode   Use  ascii  (the  default)  for  a  text  file,  which  will  be
430              translated  between  EBCDIC  and ASCII as necessary.  Use binary
431              for non-text files.
432
433       Cr     Controls how Newline characters are  handled  when  transferring
434              Mode=ascii   files.    remove   (the   default)  strips  Newline
435              characters in local files before transferring them to the  host.
436              add  adds  Newline  characters  to  each host file record before
437              transferring  it  to  the  local  workstation.   keep  preserves
438              Newline characters when transferring a local file to the host.
439
440       Remap  Controls  text  translation for Mode=ascii files.  The value yes
441              (the default) causes s3270 to remap the text to  ensure  maximum
442              compatibility   between  the  workstation's  character  set  and
443              encoding and the host's EBCDIC code page.  The value  no  causes
444              s3270  to  pass  the text to or from the host as-is, leaving all
445              translation to the IND$FILE program on the host.
446
447       Exist  Controls what happens when the destination file already  exists.
448              keep  (the  default)  preserves  the  file, causing the Transfer
449              action to fail.  replace overwrites the  destination  file  with
450              the  source  file.   append  appends  the  source  file  to  the
451              destination file.
452
453       Recfm  Controls the record format of files created on the  host.   (TSO
454              and  VM  hosts  only.)   fixed  creates a file with fixed-length
455              records.  variable creates a file with variable-length  records.
456              undefined  creates  a  file  with  undefined-length records (TSO
457              hosts only).  The Lrecl option controls  the  record  length  or
458              maximum  record length for Recfm=fixed and Recfm=variable files,
459              respectively.
460
461       Lrecl  Specifies the record length (or maximum record length) for files
462              created on the host.  (TSO and VM hosts only.)
463
464       Blksize
465              Specifies  the  block  size for files created on the host.  (TSO
466              and VM hosts only.)
467
468       Allocation
469              Specifies the units  for  the  PrimarySpace  and  SecondarySpace
470              options: tracks, cylinders or avblock. (TSO hosts only.)
471
472       PrimarySpace
473              Primary  allocation  for  a  file.   The  units are given by the
474              Allocation option.  Required when the Allocation is specified as
475              something other than default.  (TSO hosts only.)
476
477       SecondarySpace
478              Secondary  allocation  for  a  file.  The units are given by the
479              Allocation option. (TSO hosts only.)
480
481       Avblock
482              Average block size, required when Allocation specifies  avblock.
483              (TSO hosts only.)
484
485       BufferSize
486              Buffer  size  for  DFT-mode  transfers.   Can  range from 256 to
487              32768.  Larger values give better performance,  but  some  hosts
488              may not be able to support them.
489
490       There  are  also  resources that control the default values for each of
491       the file transfer parameters.  These resources have the same  names  as
492       the Transfer keywords, but with ft prepended. E.g., the default for the
493       Mode keyword is the s3270.ftMode resource.
494
495

THE PRINTTEXT ACTION

497       The PrintText produces screen snapshots in a number of different forms.
498       The  default  form  wth  no arguments sends a copy of the screen to the
499       default printer.  A single argument is the command  to  use  to  print,
500       e.g., lpr.
501
502       Multiple  arguments  can  include  keywords  to  control  the output of
503       PrintText:
504
505       file filename
506              Save the output in a file.
507
508       html   Save the output as HTML.  This option implies file.
509
510       rtf    Save the output as RichText.  This  option  implies  file.   The
511              font  defaults  to Courier New and the point size defaults to 8.
512              These can be overridden by the printTextFont  and  printTextSize
513              resources, respectively.
514
515       string Return  the  output  as  a  string.   This can only be used from
516              scripts.
517
518       modi   Render modified fields in italics.
519
520       caption text
521              Add the specified text as a caption above  the  output.   Within
522              text,   the  special  sequence  %T%  will  be  replaced  with  a
523              timestamp.
524
525       command command
526              Directs the output to a command.  This allows one or more of the
527              other  keywords  to be specified, while still sending the output
528              to the printer.
529
530

NESTED SCRIPTS

532       There are several types of nested script functions available.
533
534       The String Action
535              The simplest method for  nested  scripts  is  provided  via  the
536              String  action.  The arguments to String are one or more double-
537              quoted strings which are inserted directly as if typed.   The  C
538              backslash conventions are honored as follows.  (Entries marked *
539              mean that after sending the AID code to  the  host,  s3270  will
540              wait  for  the  host  to  unlock  the  keyboard  before  further
541              processing the string.)
542
543              \b       Left
544              \exxxx   EBCDIC character in hex
545              \f       Clear*
546              \n       Enter*
547              \pan     PA(n)*
548              \pfnn    PF(nn)*
549              \r       Newline
550              \t       Tab
551              \T       BackTab
552              \uxxxx   Unicode character in hex
553              \xxxxx   Unicode character in hex
554
555              Note that the numeric values for the \e, \u and \x sequences can
556              be abbreviated to 2 digits.  Note also that EBCDIC codes greater
557              than  255  and  some  Unicode  character  codes  represent  DBCS
558              characters,  which  will  work  only if s3270 is built with DBCS
559              support and the host allows DBCS input in the current field.
560
561              Note: The strings are in  ASCII  and  converted  to  EBCDIC,  so
562              beware of inserting control codes.
563
564              There is also an alternate form of the String action, HexString,
565              which is used to  enter  non-printing  data.   The  argument  to
566              HexString  is a string of hexadecimal digits, two per character.
567              A leading 0x or 0X is optional.  In 3270 mode,  the  hexadecimal
568              data  represent  EBCDIC  characters,  which are entered into the
569              current field.  In NVT  mode,  the  hexadecimal  data  represent
570              ASCII characters, which are sent directly to the host.
571
572       The Script Action
573              This  action  causes  s3270  to  start a child process which can
574              execute s3270 actions.  Standard input and output from the child
575              process  are  piped  back  to s3270.  The Script action is fully
576              documented in x3270-script(1).
577
578

PASSTHRU

580       s3270  supports  the  Sun  telnet-passthru  service  provided  by   the
581       in.telnet-gw server.  This allows outbound telnet connections through a
582       firewall machine.  When a p: is prepended to  a  hostname,  s3270  acts
583       much  like  the  itelnet(1)  command.   It  contacts  the machine named
584       internet-gateway at  the  port  defined  in  /etc/services  as  telnet-
585       passthru  (which  defaults  to  3514).   It  then  passes the requested
586       hostname and port to the in.telnet-gw server.
587

PROXY

589       The -proxy option or the s3270.proxy resource causes  s3270  to  use  a
590       proxy  server  to  connect  to  the  host.  The syntax of the option or
591       resource is:
592              type:host[:port]
593
594       The supported values for type are:
595
596                    Proxy Type   Protocol            Default Port
597                    ──────────────────────────────────────────────

RESOURCES

612       Certain  s3270  options can be configured via resources.  Resources are
613       defined by -xrm options.  The definitions are similar to X11 resources,
614       and use a similar syntax.  The resources available in s3270 are:
615

676
677              Note 1: m3279 defaults to False.  It can be forced to True  with
678              the proper -model option.
679
680              Note 2: The default terminal type string is constructed from the
681              model number, color emulation, and extended data  stream  modes.
682              E.g.,  a  model  2  with  color  emulation and the extended data
683              stream option would be sent as  IBM-3279-2-E.   Note  also  that
684              when  TN3270E  mode is used, the terminal type is always sent as
685              3278, but this does not affect color capabilities.
686
687              Note 3: The default trace file is  x3trc.pid  in  the  directory
688              specified by the traceDir resource.
689
690
691
692
693
694       If  more  than one -xrm option is given for the same resource, the last
695       one on the command line is used.
