unix commands to check logs

example, if you only need to record the system login and logout logs to the remote log server, you only need to modify the following line: Authpriv. * @ 192.168.10.100 192.168.10.100 is the IP address of the log server. The "@" symbol indicates that the IP address is sent to the remote host. OK. Restart the syslog service: Linux:/etc/init. d/syslogd restart BSD:/etc/rc. d/syslogd restart Use logger to test whether the configuration is successful: Log

Article Title: How to Use Syslog To record UNIX and Windows logs. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. In large-scale network applications or applications with certain security requirements, you usually need to classify and review system

backdoor password before entering and storing the password. If you press the backdoor password, it will ignore the password set by the Administrator to drive you straight into: This will allow intruders to access any account, or even the root directory. Because the backdoor password is an access generated before the user logs on and is logged to utmp and wtmp, intruders can log on to the shell without exposing this account. After the Administrator no

On the linux/unix platform, it is not difficult to check which databases or instances exist on the OS. As some colleagues asked this question, I wrote down the method, someone may ask, but maybe another person may not. I hope it will help some friends who are not or just new. On the linux/unix platform, you can view the number of databases on the OS. There are th

as the input of another command, you can use the pipeline symbol |. The following shows that the echo output is used as the input of sort using the pipeline. [root@localhost ~]# echo -e "apple\npear\nbanana" | sortapplebananapear[root@localhost ~]# Each command may have options or parameters. You can also use | to output the second command as the input of the Third Command, and so on. It is a common method in Linux/Unix to build a long command pipel
