The establishment of FTP server based on UNIX platform

At present, many enterprise organizations are framing their own intranet,ftp server is one of the service support, a number of units to purchase a UNIX-based platform of computers, in order to be able to provide FTP service online support, specialized in the acquisition of Unix-based platform FTP server software, In fact, based on the UNIX platform of Computer systems, to take certain technical methods, you can set up their own FTP Server, to achieve online file download services, no need to purchase specialized software, and music and not for it? The following is an elaboration of its establishment process:

1, determine the FTP server's shared directory

Create an FTP working directory for FTP server, which is set to/home/ftp

2, write the FTP server initial settings of the shell program (Setup)

Use an editing tool (such as VI) to write a shell program to set up the system.

The following are the referenced contents: #!/bin/sh Case $# in 0) ftphome= "' grep ' ^ftp: '/etc/passwd | cut-d:-f6 ' " ;; 1 if ["$" = "start"]; Then Ftphome= "' grep ' ^ftp: '/etc/passwd | cut-d:-f6 ' " Else Ftphome=$1 Fi ;; *) echo "Usage: $ [Anon-ftp-root]" Exit 1 ;; Esac If [-Z "${ftphome}"]; Then echo "$0:ftphome must be Non-null" Exit 2 Fi if ["${ftphome}" = "/"-O "${ftphome}" = "/usr"]; Then echo "$0:ftphome must not BE/OR/USR" Exit 2 Fi if [!-D ${ftphome}]; Then mkdir ${ftphome} Fi if [!-D ${ftphome}/usr/bin]; Then Mkdir-p ${ftphome}/usr/bin Fi Cp/usr/bin/ls ${ftphome}/usr/bin chmod ${ftphome}/usr/bin/ls Chown Root ${ftphome}/usr/bin chmod 555 ${ftphome}/usr/bin If [R ${ftphome}/bin]; Then Mv-f ${ftphome}/bin ${ftphome}/obin Fi Ln-s Usr/bin ${ftphome} if [!-D ${ftphome}/usr/lib]; Then Mkdir-p ${ftphome}/usr/lib Fi if [!-D ${FTPHOME}/ETC]; Then Mkdir-p ${ftphome}/etc Fi Cp/usr/lib/ld.so/usr/lib/ld.so.1 ${ftphome}/usr/lib For Lib in libc libdl libintl libw libnsl libsocket \ Nss_nis Nss_nisplus Nss_dns Nss_files Todo Cp/usr/lib/${lib}.so.1 ${ftphome}/usr/lib Rm-f ${ftphome}/usr/lib/${lib}.so Ln-s./${lib}.so.1 ${ftphome}/usr/lib/${lib}.so Done Cp/usr/lib/straddr.so.2 ${ftphome}/usr/lib Rm-f ${ftphome}/usr/lib/straddr.so Ln-s./straddr.so.2 ${ftphome}/usr/lib/straddr.so Cp/etc/passwd/etc/group/etc/netconfig ${ftphome}/etc chmod 555 ${ftphome}/usr/lib/* chmod 444 ${ftphome}/etc/* Chown Root ${ftphome}/usr/lib ${ftphome}/etc chmod 555 ${ftphome}/usr/lib ${ftphome}/etc if [!-D ${ftphome}/dev]; Then Mkdir-p ${ftphome}/dev Fi prefix= "/devices/pseudo/mm@0:" For device in Zero Todo Line= ' Ls-l ${prefix}${device} | Sed-e ' s/,//' Major= ' echo $line | awk ' {print $} ' Minor= ' echo $line | awk ' {print $} ' Rm-f ${ftphome}/dev/${device} Mknod ${ftphome}/dev/${device} C ${major} ${minor} Done prefix= " /devices/pseudo/clone@0: " For device in TCP UDP Ticotsord Todo Line= ' Ls-l ${prefix}${device} | Sed-e ' s/,//' Major= ' echo $line | awk ' {print $} ' Minor= ' echo $line | awk ' {print $} ' Rm-f ${ftphome}/dev/${device} Mknod ${ftphome}/dev/${device} C ${major} ${minor} Done chmod 666 ${ftphome}/dev/* Chown Root ${ftphome}/dev chmod 555 ${ftphome}/dev #建立一个匿名FTP服务目录, and set up readable writable properties if [!-D ${ftphome}/pub]; Then Mkdir-p ${ftphome}/pub Fi Chown FTP ${ftphome}/pub chmod 777 ${ftphome}/pub

3. Edit/etc/passwd and/etc/shadow documents

To set up an anonymous FTP account, add the following data items to the/etc/passwd and/etc/shadow two files, respectively, in the following ways:

(1) Increase in the/etc/passwd file

Ftp:x:30000:30000:anonymous Ftp:/home/ftp:/nosuchshell

(2) Increase in the/etc/shadow file

ftp:np:6445:::::

4., run the Setup program

Before you run the Setup program, set the file as the execution file

#chmod +x Setup

Run the Setup program #setup/home/ftp

The above steps to complete the establishment of the FTP server, you can use the FTP server, such as Explorer, Netscape Navigator and other browsers to access the FTP server, download and upload file operations, the use of very convenient.
