When using ssh to log on to a remote host (suse linux), the following problems occur: Ssh_exchange_identification: Connection closed by remote host, This problem is caused by SSH security restrictions. Although it is a good solution, it is necessary to go to the IDC site (because the security regulations do not enable VNC ). Solution: Modify the/etc/hosts. allow file, add the sshd: ALL: ALLOW file, and t

*/etc/inetd.conf File As we all know, as a server, the more open the service port, the more difficult to guarantee the security stability of the system. So servers that provide specific services should be as open as possible to the ports that provide the service, and the services unrelated to the server will be shut down, for example, a machine that is a WWW and FTP server should open only 80 and 25 ports and turn off other unrelated services such as finger auth. To reduce system vulnerabilities

A bare device is a non-formatted partition or disk. It is also called a bare partition (original partition) and is not read by UNIX through a file system. The application is responsibleIt performs read/write operations. A device that is not directly managed by the operating system without being buffered by the file system. I/O efficiency is improved because I/O is managed across operating systems. In SuSE LinuxOracle 10 Gb does not support storing OCR
