Solaris log file full

System log files are rotated by the logadm command from an entry in the root crontab file. This file includes log rotation entries for processes such as syslogd. The most recent syslog file becomes syslog. Eight previous syslog log files are kept. You can use the logadm command as superuser or by assuming an equivalent role with Log Management rights.

With RBAC, you can grant non-root users the privilege of maintaining log files by providing access to the logadm command. Crash and boot messages are stored here as well. A facility or system source of the message or condition. May be a comma-separated listed of facilities. Facility values are listed in Table A level , indicates the severity or priority of the condition being logged. Priority levels are listed in Table Do not put two entries for the same facility on the same line, if the entries are for different priorities.

Putting a priority in the syslog file indicates that all messages of that all messages of that priority or higher are logged, with the last message taking precedence. For a given facility and level, syslogd matches all messages for that level and all higher levels. User messages requiring immediate action alert are sent to the root and operator users.

Note that you can specify multiple selectors in a single line entry, each separated by a semicolon. The most common error condition sources are shown in the following table. The most common priorities are shown in Table in order of severity. The consadm command enables you to select a serial device as an auxiliary or remote console.

Using the consadm command, a system administrator can configure one or more serial ports to display redirected console messages and to host sulogin sessions when the system transitions between run levels. This feature enables you to dial in to a serial port with a modem to monitor console messages and participate in init state transitions. For more information, see sulogin 1M and the step-by-step procedures that follow. While you can log in to a system using a port configured as an auxiliary console, it is primarily an output device displaying information that is also displayed on the default console.

If boot scripts or other applications read and write to and from the default console, the write output displays on all the auxiliary consoles, but the input is only read from the default console. For more information about using the consadm command during an interactive login session, see Using the consadm Command During an Interactive Login Session.

The consadm command runs a daemon to monitor auxiliary console devices. Any display device designated as an auxiliary console that disconnects, hangs up or loses carrier, is removed from the auxiliary console device list and is no longer active.

Input cannot come from an auxiliary console if user input is expected for an rc script that is run when a system is booting. The input must come from the default console. The sulogin program, invoked by init to prompt for the superuser password when transitioning between run levels, has been modified to send the superuser password prompt to each auxiliary device in addition to the default console device.

When the system is in single-user mode and one or more auxiliary consoles are enabled using the consadm command, a console login session runs on the first device to supply the correct superuser password to the sulogin prompt. When the correct password is received from a console device, sulogin disables input from all other console devices. A message is displayed on the default console and the other auxiliary consoles when one of the consoles assumes single-user privileges.

This message indicates which device has become the console by accepting a correct superuser password. If there is a loss of carrier on the auxiliary console running the single-user shell, one of two actions might occur:.

If the auxiliary console represents a system at run level 1, the system proceeds to the default run level. If there isn't any carrier on that device either, you will have to reestablish carrier and enter the correct run level. The init or shutdown command will not re-display the run-level prompt. If you are logged in to a system using a serial port, and an init or shutdown command is issued to transition to another run level, the login session is lost whether this device is the auxiliary console or not.

This situation is identical to releases without auxiliary console capabilities. Our platform also allows you to set up alerts to gain real-time insights on system events affecting the security of your devices.

Download root. There are many TLS bugs in past versions. Ensure you have not a single infront of the host. This is so TCP is used. This task can be automated by using log analysis tools or a simple grep command. Application log files are created and maintained by commands and tools without using the syslog system. The Solaris Operating Environment includes several commands that maintain their own log files. Here is a list of some of the Solaris Operating Environment log files:.

If this file exists, the login program records failed login attempts. All of these logs should also be monitored for problems. This file is a catch-all log file for a number of messages from the UNIX kernel as well as for other logging applications such as syslogd. The file is formatted as an ASCII text file and entries are usually one record per line with new entries appended to the end of the file.

The following is a sample excerpt from a messages file. Each pair of lines shown below appears as one line in the file:.

Note that the messages file can get very large quickly and should be rotated regularly to ensure that it does not consume too much local disk space. Refer to "Using newsyslog to rotate files containing logging messages on systems running Solaris " for more information.

An entry is added to the sulog file every time the su command is executed. Look for entries where an unauthorized user has used the command inappropriately.

Look for su occurring at unusual times during the day e. An example last command output is. See also How to rotate wtmpx in solaris.

The install log contains all of the character output generated throughout Solaris installation. The log contains information such as disk partitioning and formatting, software module installation status, and mount points.

This log can be useful for double-checking the configuration of a newly installed or reinstalled system to see what, if any, changes have occurred. One particular shortcoming of the Solaris default installation is that auth.

These files contain user and accounting information that is recorded when a user logs in, logs out, or starts a new shell process with an application such as xterm or screen.

Records written to these log files by the managing application contain account activity for the system. The data in these files are written as binary data so they must be read by a tool specifically designed to do so, such as last 1 and who 1. See the system man pages for last 1 and who 1 for additional information on the data and display formats available with these tools.

This binary log file stores information about a user who has logged into the system. It is kept up to date by utilities such as login 1 and in. The data are viewable with tools such as last 1 , who 1 , and finger 1. Refer to the system man pages for more information. The sulog file is a record of all attempts by users on the system to execute the su 1M command. Each time su 1M is executed, an entry is added to the sulog file. The following is a sample excerpt from a sulog file:.

For example, the following syslog. This log file is created by the sysidconfig 1M command, which executes system configuration applications or defines a set of system configuration applications.

Specific information about this and other related system configuration tools can be found in the system man pages for sysidconfig. This file contain log entries for cron 1M and at 1 jobs that have been run on the local machine. This file is a text file that lists the command that was run, at what time, and as what user. The following example log file contains both a cron and at job entry:.

These logs keep track of users currently logged into the system. Using the who command, check the users logged in at the current time:. Look for user logins that are unexpected e. Look for anything that looks unusual.
