To configure services:
Complete or view the following:
Alert Levels |
Select one of the following alert levels from the drop-down list for each message category: Off: Disables this type of logging. Error: Saves messages that are output because of an error. Warning: Saves message output from a condition that may be cause for concern, in addition to error messages. This is the default for all message types. Info: Saves informative message, in addition to warning and error messages. Debug: Saves extraneous detail that may be helpful in tracking down a problem, in addition to information, warning, and error messages. |
Network Level |
Messages concerning the network activity, for example about Ethernet and routing. |
Services |
Messages concerning services such as SNMP and SMTP. |
Authentication |
Messages concerning user authentication. |
Device Ports |
Messages concerning device ports and connections. |
Diagnostics |
Messages concerning system status and problems. |
General |
Any message not in the categories above. |
Remote Servers (#1 and #2) |
IP address of the remote server(s) where system logs are stored. The system log is always saved to local SLC or SLB storage. It is retained through SLC or SLB unit reboots for files up to 200K. Saving the system log to a server that supports remote logging services (see RFC 3164) allows the administrator to save the complete system log history. |
Enable Logins |
Enables or disables SSH logins to the SLC or SLB unit to allow users to access the CLI using SSH. Enabled by default. This setting does not control SSH access to individual device ports. (Device Ports – Settings provides information on enabling SSH access to individual ports.) Most system administrators enable SSH logins, which is the preferred method of accessing the system. |
Web SSH |
Enables or disables the ability to access the SLC or SLB command line interface or device ports (connect direct) through a web SSH window. Disabled by default. |
Timeout |
If you enable SSH 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. Note: You must reboot the unit before a change will take effect. |
SSH Port |
Allows you to change the SSH login port to a different value in the range of 1 - 65535. The default is 22. Note: You must reboot the unit before a change will take effect. |
SSH V1 Logins |
Enables or disables SSH version 1 incoming connections to the SLC or SLB unit. Enabled by default. Note: Disabling SSH V1 blocks Web SSH CLI and Web SSH to device port connections on the SLC/SLB Network page. Also, you must reboot the SLC or SLB unit before a change will take effect. |
DSA Keys |
Enables or disables support for DSA keys for incoming and outgoing connections for the SLC or SLB unit. Any imported or exported DSA keys will be retained but will not be visible on the web or the CLI. Enabled by default. |
Enable Logins |
Enables or disables Telnet logins to the SLC or SLB unit to allow users to access the CLI using Telnet. Disabled by default. This setting does not control Telnet access to individual device ports. (Device Ports – Settings provides information on enabling Telnet access to individual ports.) You may want to keep this option disabled for security reasons. |
Web Telnet |
Enables or disables the ability to access the SLC or SLB command line interface or device ports (connect direct) through a 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. Note: You must reboot the unit before a change will take effect. |
Escape Sequence |
A single character or a two-character sequence that causes the SLC or SLB 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 hexidecimal 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 |
Enables or disables the ability to create Telnet out connections. |
Enable Log |
Select to save a history of all configuration changes in a circular log. Disabled by default. The audit log is saved through SLC or SLB unit reboots. |
Size |
The log has a default maximum size of 50 Kbytes (approximately 500 entries). You can set the maximum size of the log from 1 to 500 Kbytes. |
Include CLI Commands |
Select to cause the audit log to include the CLI commands that have been executed. Disabled by default. |
Include In System Log |
If enabled, the contents of the audit log are added to the system log (under the General/Info category/level). Disabled by default. |
Server |
IP address of your network’s Simple Mail Transfer Protocol (SMTP) relay server. |
Sender |
The email address of the sender of outgoing emails. The strings "$host" and "$domain" can be part of the email address - they will be substituted with the actual hostname and domain. The default is donotreply@$host.$domain. |
Terminal Buffer Size |
Number of lines in the Web SSH or Web Telnet terminal window that are available for scrolling back through output. |
Enable |
If enabled, the SLC or SLB unit will attempt to phone home every hour until it has contacted an SLM device and provided it with its configuration. |
IP Address |
IP address of the SLM unit. |
Last Attempt (display only) |
Date and time of last connection attempt. |
Results (display only) |
Indicates whether the attempt was successful. |
