An <i>IBM host</i> is a host which can communicate with a 3270 terminal emulator such as <b>x3270</b> or <b>c3270</b>. Each line defines a name in the following format (optional fields are shown in brackets): <p> <i>name</i> <i>type</i> [<i>opt</i>:]...[<i>luname</i>@]<i>hostname</i>[:<i>port</i>] [<i>actions</i>] <p> Items are separated by any number of blanks and/or TAB characters. A line beginning with # is taken as a comment (note that # anywhere else on a line does <i>not</i> indicate a comment). <p> The <i>name</i> field is a mnemonic used to identify the host. <p> The <i>type</i> field is a keyword that indicates the type of entry. The value <b>primary</b> means that the <i>name</i> will be included in host-selection menus that may be displayed by a 3270 emulator. The value <b>alias</b> means that the <i>name</i> will not be included in menus, but will still be accepted as valid input when a host name is required. <p> The <i>hostname</i> field is the Internet hostname or dot-notation Internet address of the host. <p> The <i>hostname</i> can include `s:' or `p:' prefixes, e.g., <b>s:finicky</b> (see the <a HREF="x3270-man.html"><i>x3270</i>(1)</a> or <a HREF="c3270-man.html"><i>c3270</i>(1)</a> man page sfor details). It can also include an LU name, separated by an `@' character, e.g., <b>oddlu@bluehost</b>. Finally, it can include a non-default <i>port</i> number, appended to the <i>hostname</i> with a colon `:' character, e.g., <b>bluehost:97</b>. (For compatability with earlier versions of <i>x3270</i>, the <i>port</i> can also be separated by a slash `/' character.) <p> The optional <i>actions</i> field specifies actions to be taken once the connection is made and a data-entry field is defined. If the text looks like an action, e.g., <b>PF(1)</b>, it is unmodified; otherwise it is taken as the parameter to the <b>String()</b> action. The <i>actions</i> are not intended for entering usernames and passwords; rather they provide an automated way of specifying a front-end menu option. <a NAME="Example"></a><h2>Example</h2> Given the following <b>ibm_hosts</b> file: <p> <blockquote>mvs primary mvs-host <br> tso alias mvs-host <br> mvs2 primary mvs-host:4012 <br> vm primary vtam Tab() String(3) Enter() </blockquote> A 3270 emulator will display four names (<b>mvs</b>, <b>mvs2</b>, <b>afhost</b> and <b>vm</b>) on its hosts menu. The names <b>mvs</b> and <b>tso</b> will cause connections to the host <b>mvs-host</b>. The name <b>mvs2</b> will also cause a connection to <b>mvs-host</b>, but to port 4012 rather than the emulator's default port (usually 23). The name <b>vm</b> will cause the 3270 emulator to connect to the host <b>vtam</b> (presumably some sort of host-selection front-end), enter the string `3' on the second data-entry field on the screen, and send the Enter <font size=-1>AID</font> sequence. <a NAME="Files"></a><h2>Files</h2> /usr/lib/X11/x3270/ibm_hosts <a NAME="See-Also"></a><h2>See Also</h2> <a HREF="x3270-man.html">x3270(1)</a>, <a HREF="c3270-man.html">c3270(1)</a> <hr> <i> This HTML document and the accompanying troff document were generated with a set of write-only <b>m4</b> macros and the powerful <b>vi</b> editor. <br>Last modified 23 March 2009. </i> </body> </html>
