vsftpd安装故障排除

/alan00000/article/details/7194702 1 、下载Ubuntu上的ftp客户端软件filezilla安装： sudoapt-get installfilezilla安装完成后，在应用程序-互联网会看到采用ftp客户端filezilla下载：/users/cevans/untar/ 下载vsftpd-2.3.42 、修改Makefile文件CC=arm-linux-gcc3 、执行make若出现错误-/bin/sh:./vsf_findlibs.sh: Permission deniedsysdeputil.o: In functionvsf_sysdep_check_auth:sysdeputil.c:(.text+0xdcc): undefinedreference to cryptsysdeputil.c:(.text+0xdf0): undefinedreference to cryptcollect2: ld returned 1 exit statusmake:* vsftpd 错误1修改./vsf_findlibs.sh属性为可读写与执行-/lib/libcap.so.2:could not read symbols: File in wrong formatcollect2: ld returned1 exit statusmake: * vsftpd 错误1修改vsffindlibs.sh：屏蔽掉49-57行；-如果之后再出现sysdeputil.o:In function vsf_sysdep_check_auth:sysdeputil.c:(.text+0xdcc):undefined reference to cryptsysdeputil.c:(.text+0xdf0):undefined reference to cryptcollect2: ld returned 1 exitstatusmake: * vsftpd 错误 1那么就把/usr/local/arm/4.3.2/arm-none-linux-gnueabi/libc/lib/下的libcrypt.so.1复制到开发板根文件系统/lib目录下至于为什么这么处理我也想不明白。4 、执行arm-linux-readelf-d vsftpd显示需要哪些库，如下：Dynamicsection at offset 0x170fc contains 29 entries: Tag Type Name/Value0x00000001 (NEEDED) Shared library: libcrypt.so.1 0x00000001(NEEDED) Shared library: libc.so.60x0000000c(INIT) 0x96800x0000000d(FINI) 0x1b3f40x00000019(INIT_ARRAY) 0x26a580x0000001b(INIT_ARRAYSZ) 4 (bytes)0x0000001a(FINI_ARRAY) 0x26a5c0x0000001c(FINI_ARRAYSZ) 4 (bytes)0x00000004(HASH) 0x81680x00000005(STRTAB) 0x8d080x00000006(SYMTAB) 0x84f80x0000000a(STRSZ) 1100 (bytes)0x0000000b(SYMENT) 16 (bytes)0x00000015(DEBUG) 0x00x00000003(PLTGOT) 0x26b540x00000002(PLTRELSZ) 984 (bytes)0x00000014(PLTREL) REL0x00000017(JMPREL) 0x92a80x00000011(REL) 0x92980x00000012(RELSZ) 16 (bytes)0x00000013(RELENT) 8 (bytes)0x6ffffffe(VERNEED) 0x92580x6fffffff(VERNEEDNUM) 20x6ffffff0(VERSYM) 0x91540x00000000(NULL) 0x0把libcrypt.so.1l libc.so.6 及这两个连接所指向的源文件用cp-a 复制到根文件系统的/lib另外还有libnss_files.so.2及该连接所指向的源文件， 否则运行时会出现：500OOPS: vsftpd: cannot locate user specified inftp_username:ftp错误；（这点错误弄了一晚上好几个小时）ps：好帅老师辛苦了5 、把生成的vsftpd拷贝到根文件系统的sbin目录，vsftpd.conf文件拷贝到根文件系统的etc目录下6 、配置vsftpd.conf对配置文件进行了修改，我的： #Example config file /etc/vsftpd.conf# The default compiledin settings are fairly paranoid.
