根據自己的需要,修改Makefile,將gcc修改爲交叉工具鏈的gcc,比如mips-gnu-linux-gcc。
若要靜態編譯,在CFLAGS後面添加"-static"選項。
以下的Makefile已經修改:
- #
- #
- # Makefile for the linux version of stupid-ftpd
- #
- #
- #
- CC=mips-linux-gnu-gcc -EL #修改
- OBJS=ftpcommand.o ftpdconfig.o command.o ls.o stupid-ftpd.o
- DOBJS=ftpcommand.do ftpdconfig.do command.do ls.do stupid-ftpd.do
- POBJS=ftpcommand.po ftpdconfig.po command.po ls.po stupid-ftpd.po
- LIBS=
- CFLAGS=-O2 -Wall -Wstrict-prototypes -static #修改
- DCFLAGS=-g -DDEBUG -Wall -Wstrict-prototypes
- PCFLAGS=-g -DDEBUG -Wall -Wstrict-prototypes -Wcast-align -Wwrite-strings -Wconversion -Waggregate-return -Wmissing-prototypes -Wmissing-declarations -Wredundant-decls -Wnested-externs
- EXEC=stupid-ftpd.Linux6
- .SUFFIXES: .c .o .do .po
- all: $(OBJS)
- $(CC) $(CFLAGS) -o $(EXEC) $(OBJS) $(LIBS)
- debug: $(DOBJS)
- $(CC) $(DCFLAGS) -o $(EXEC) $(DOBJS) $(LIBS)
- pedantic: $(POBJS)
- $(CC) $(PCFLAGS) -o $(EXEC) $(POBJS) $(LIBS)
- clean:
- rm -f $(OBJS) $(DOBJS) $(POBJS) $(EXEC) *~
- .c.o:
- $(CC) $(CFLAGS) -c -o $@ $<
- .c.do:
- $(CC) $(DCFLAGS) -c -o $@ $<
- .c.po:
- $(CC) $(PCFLAGS) -c -o $@ $<
- install:
- install -m 755 -s ./stupid-ftpd /usr/local/bin/stupid-ftpd
- install -m 700 -d /etc/stupid-ftpd
- install -m 755 -d /usr/local/stupid-ftpd
- install -m 600 ./stupid-ftpd.conf /etc/stupid-ftpd/stupid-ftpd.conf
只需修改兩個位置。
編譯完成後,生成stupid-ftpd.Linux6可執行程序,該程序運行需要配置文件,以下的配置已經被修改並驗證,是可以用的。但前提是運行在嵌入式Linux系統下,21端口沒有被佔用。
- #
- # This is a config-file for stupid-ftpd
- # ------------------------------------
- #
- # The standard path should be /etc/stupid-ftpd.conf
- # You can define other paths by using the "-f" option
- # when starting stupid-ftpd.
- #
- #
- # ATTENTION: 1) Remember, that the server is running with YOUR permissions.
- # It will fail to access other users directory, unless it is
- # root, but it also allows to access ALL YOUR directories,
- # which are deeper in a user's root-dir and YOU HAVE access to.
- # 2) To solve the problem, the best way is to define a group-ID
- # for stupid-ftpd.
- # Or if you aren't root: set the MAIN root (serverroot=) to
- # the highest directory depth which is possible.
- # 3) REMEMBER: DO NOT PUT THIS FILE in an accessible directory!!!
- # There are passwords defined here. The safest place is
- # outside the serverroot.
- # Server operation mode:
- # daemon - quiet in background
- # interactive - standard mode
- #mode=interactive #交互式的形式運行
- mode=daemon #以守護進程的形式運行在後臺
- # chroot to
- #serverroot=/usr/home/cinek/tmp3/aaa
- serverroot=/mnt #將ftp的根目錄設置爲/mnt目錄下,在windows打開該ftp,就能訪問/mnt目錄
- # type of chroot
- # real - kernel chroot(), high security, but needs root privileges
- # virtual - no real chroot(), software side (virtual) chroot
- #changeroottype=real
- changeroottype=virtual
- # Port number for the FTP-Protocol
- #port=2121
- port=21 #默認爲ftp的端口號。
- # Maximum users allowed to log in
- maxusers=10
- # Message Of The Day (motd)
- # It will be displayed after the login procedure.
- #motd=/tmp/stupid-ftpd.motd
- # Message on quit
- # It will be displayed when quitting.
- #byemsg=/tmp/stupid-ftpd.bye
- # Log
- #log=/tmp/stupid-ftpd.log
- # User list:
- # Format: user=<login> <passwd> <subdir> <maxlogins> <flags>
- # <login> user name
- # <passwd> password or * for anonymous access
- # <subdir> (internally appended to serverroot)
- # the user has access to the WHOLE SUBTREE,
- # if the server has access to it
- # <maxlogins> maximal logins with this usertype
- # <flags> D - download
- # U - upload + making directories
- # O - overwrite existing files
- # M - allows multiple logins
- # E - allows erase operations
- # A - allows EVERYTHING(!)
- #
- # user ftp is mapped to user anonymous, don't forget this
- #
- # Examples:
- # user=user1 passx /tmp 2 D
- # - login: user1, passwd: passx, max login twice (different IPs!)
- # only download rights from directory /tmp
- # user=user2 passy /home/user2 0 DU
- # - login: user2, passwd: passy, no login count limit (different IPs!)
- # download+upload rights to directory /home/user2
- # user=user3 passz /home/user3 5 DUOM
- # - login: user3, passwd: passz, max login count 5 (even from same IP)
- # download+upload+overwrite rights to directory /home/user3
- # user=user4 passq /tmp 10 -
- # - login: user4, passwd: passq, max login count 10 (even from same IP)
- # look-only rights at directory /tmp
- #
- # SEE: ATTENTION remark on the top of this file !!!
- user=anonymous * / 5 A
- # Banned hosts
- # "*" and "?" are allowed here
- #ban=192.168.*
- #ban=localhost
- #ban=*.banme.com
- # Ban message (displayed to user who is banned)
- # Please don't use more than 70 characters.
- #banmsg=Go away !
- # Login/password timeout
- login-timeout=120
- # Timeout (while logged in)
- timeout=240
剩下的用默認的配置就可以了,特別注意,設置port參數的時候,2121端口不能使用,無法提供ftp服務。要設置爲21端口,經過測試,設置爲21端口,在Linux的PC機,報錯:21端口被佔用。但在嵌入式Linux下,是可以使用的。
stupid-ftpd.Linux6的使用方法:
直接用-f選項指定配置文件:
stupid-ftpd.Linux6 -f stupid-ftpd.conf
然後保證windows與嵌入式Linux系統的IP地址在同一網段,然後再"我的電腦"輸入:ftp://192.168.x.x/
這裏就不截圖了。
