Online, etc! In RedHatLinux9.0, the peanut shells and VSFTPD are started normally, and other machines cannot access the FTP server. -- Linux Enterprise Application-Linux server application information. For details, refer to the following section. (6) m: B: 0w223dc is installed with a peanut shell (Linux version) and VSFTPD on the local machine to form an FTP server.
In the local machine (192.168.1.168) Input ftp: // 192.168.1.168 or ftp://meituftp.vicp.net can be accessed.
You can also enter ftp: // 192.168.1.168 on other machines in the LAN, but the entered domain name cannot be accessed (see figure ).
Is this fault caused by peanut shells. If it wasn't caused by a peanut shell, why? How can this problem be solved?
I hope you will kindly advise me.
Thank you !!!!!
