7: Services Port Security Test Email Email Address Comment View SMTP Log The TCP port that the SMTP server listens to. Before the introduction of secure email (with StartTLS or TLS), port 25 was the standard port for SMTP. However, with the rise of spam, fewer email services use port 25 and now use port 465 for TLS and port 587 for StartTLS.The default port is 25. Enables TLS encrypted connections to the SMTP server. Select StartTLS to initiate a connection in unencrypted mode but switch to TLS if it can negotiate with the server, and select TLS to use only use encrypted connection mode with the server. This option is disabled by default. Select the check box to send a test email. Email address to send the test email. Allows you to provide a comment, if desired. Allows you to view SMTP logs. Telnet Enable Logins Web Telnet Enables or disables Telnet logins to the SLC unit to allow users to access the CLI using Telnet. Disabled by default. This setting does not control Telnet access to individual device ports. (See Device Ports > Settings (1 of 2) (on page 187) for information on enabling Telnet access to individual ports.) You may want to keep this option disabled for security reasons. Enables or disables the ability to access the SLC command line interface or device ports (connect direct) through the Web Telnet window. Disabled by default. Timeout If you enable Telnet logins, you can cause an idle connection to disconnect after a specified number of minutes. Select Yes and enter a value of from 1 to 30 minutes. Timeout Data Direction If idle connection timeouts are enabled, this setting indicates the direction of data used to determine if the connection has timed out. Select the type of data direction:  Both Directions  Incoming Network  Outgoing Network Escape Sequence A single character or a two-character sequence that causes the SLC unit to terminate a Telnet client. Currently the Escape Sequence is only used for Web Telnet sessions. The default value is Esc+T (escape key, then uppercase "T" performed quickly but not simultaneously). You would specify this value as \x1bT, which is hexadecimal (\x) character 27 (1B) followed by a T. A control character can be specified with the hexadecimal number for the control character; for example, Control-E can be specified as \x05. Note that some browsers do not report key press events if Control is pressed for non-alphanumeric keys, so it is recommended to only use letters with Control character sequences. Outgoing Telnet Enables or disables the ability to create Telnet out connections. Web SSH/Web Telnet Settings Terminal Buffer Size Number of lines in the Web SSH or Web Telnet terminal window that are available for scrolling back through output. Note: For tips on browser issues with Web SSH or Web Telnet, see Browser Issues on page 151. SLC™ 8000 Advanced Console Manager User Guide 136
