Terminology and examples are based on a couple of popular Jabber clients (<a href=\"http:\/\/psi.affinix.com\/\">Psi<\/a>\u00a0&amp;\u00a0<a href=\"http:\/\/gaim.sourceforge.net\/\">Gaim<\/a>), but should be similar on other clients.<\/p>\n<h3>Jabber Client Software<\/h3>\n<p>You need a Jabber client software to use the jabber service. Most IM software also supports Jabber. Check the following link for an extensive list of client software:<\/p>\n<p><a href=\"http:\/\/www.jabber.org\/software\/clients.shtml\">http:\/\/www.jabber.org\/software\/clients.shtml<\/a><\/p>\n<h3>Account Registration<\/h3>\n<p>Registration is required for every new user to create a new account. Select a Jabber ID (JID) in the form of &#8220;foo@jabber.postel.org&#8221;, replace &#8220;foo&#8221; with your screen name. Registration is not needed when setting up a new client software with an existing account.<\/p>\n<p>Add a new account in your clients:<\/p>\n<ul>\n<li>Psi: check &#8220;Register new account&#8221; &amp; enter the complete Jabber ID (including &#8220;@jabber.postel.org&#8221;) in the &#8220;Jabber ID&#8221; field<\/li>\n<li>Gaim: enter the screen name (foo) and server name (jabber.postel.org) separately, then click &#8220;Register&#8221;<\/li>\n<\/ul>\n<p>Note that you also need to setup the correct connection parameters described below in order to register.<\/p>\n<h3>Server<\/h3>\n<ul>\n<li>jabber.postel.org<\/li>\n<\/ul>\n<h3>Connection Settings<\/h3>\n<p>The server is open, supports both unencrypted and encrypted (TLS\/SSL) connections using non-plaintext (hashed) passwords on the default ports (5222\/5223). Default settings on most clients should work. The following settings are recommended:<\/p>\n<p>Select one of the following<\/p>\n<ul>\n<li>[x] Use TLS if available \/ STARTTLS (if the client applications support TLS such as Gaim)<\/li>\n<li>[x] Use SSL encryption \/ Force old SSL (Psi does not support TLS)<\/li>\n<\/ul>\n<p>Uncheck<\/p>\n<ul>\n<li>[ ] Allow Plaintext Login \/ Allow plaintext auth over unencrypted streams<\/li>\n<\/ul>\n<p>Ports (for reference only, they are the same as the default on most clients):<\/p>\n<ul>\n<li>5222: TLS (STARTTLS) or unencrypted<\/li>\n<li>5223: SSL<\/li>\n<\/ul>\n<h2>Proxy Setup<\/h2>\n<p>This is only needed when you are behind a firewall that blocks the default jabber ports (5222\/5223). Please use the following parameters:<\/p>\n<ul>\n<li>Type: HTTP Polling (NOT HTTP or HTTP Connect)[*]<\/li>\n<li>Host: (blank)<\/li>\n<li>Port: 0<\/li>\n<li>Polling URL: http:\/\/jabber.postel.org:80\/http-poll<\/li>\n<\/ul>\n<p>[*] Unfortunately, Gaim does not seem to support HTTP Polling, and the server on jabber.postel.org does not support HTTP (HTTP Connect).<\/p>\n<h2>MUC &#8211; Multi-User Chat (Chatroom) Service<\/h2>\n<p>MUC services is enabled on jabber.isi.edu. Users could create chatrooms and invite other users to join.<\/p>\n<p>To create or join a chatroom, use the following parameters:<\/p>\n<ul>\n<li>Server\/Host: conference.jabber.postel.org<\/li>\n<li>Room: (the name of the chatroom)<\/li>\n<li>Handle\/Nickname: (the name you will appear in the room)<\/li>\n<li>Password: (blank)<\/li>\n<\/ul>\n<p>Note that to create a chatroom, a user simply needs to join an unused room. You can also get a list of active or permanent rooms either through &#8220;Room List&#8221; menu or &#8220;Service Discovery&#8221; on your Postel.org jabber account. Specify &#8220;conference.jabber.postel.org&#8221; as the conference server when prompted. On service discovery, chatrooms are listed under &#8220;ejabberd\/mod_muc.&#8221;<\/p>\n<h2>Notes<\/h2>\n<h3>Psi Warning on Self-Signed Certificates<\/h3>\n<p>Because jabber.postel.org uses self-signed certificate on the server side for SSL\/TLS encryption, some clients will generate warning messages such as this:<\/p>\n<p>&#8220;The jabber.postel.org certificate failed the authenticity test. Reason: Certificate is self-signed.&#8221;<\/p>\n<p>This only means the certificate for jabber.isi.edu is not signed by any one of the commercial certificate authority ($199+ per year).<\/p>\n<p>There are two ways to avoid the warning message:<\/p>\n<p>(1) Under &#8220;Account Properties&#8221; =&gt; &#8220;Preference&#8221; tab: Check or select &#8220;Ignore SSL warnings&#8221;.<\/p>\n<p>(2) Download the certificate file from the following location and copy it to the Psi root certificate directory:\u00a0<a href=\"http:\/\/www.isi.edu\/div7\/jabber\/jabber.isi.edu.xml\">http:\/\/www.postel.org\/jabber\/jabber.postel.org.xml<\/a><\/p>\n<p>Psi root certificate directory:<\/p>\n<ul>\n<li>FreeBSD: \/usr\/local\/share\/psi\/certs<\/li>\n<li>Linux:<\/li>\n<li>Mac OSX: \/Applications\/Psi.app\/Contents\/Resources\/certs<\/li>\n<li>Windows:<\/li>\n<\/ul>\n\n","protected":false},"excerpt":{"rendered":"<p>Information This page describes the Jabber service hosted at\u00a0ISI\u00a0Postel Center.
