vsftpd的配置文件/etc/vsftpd.conf把中"listen=YES"和"listen_ipv6=YES"是不能同时开启。 默认配置下"listen=YES"开启，"listen_ipv6=YES"被注释掉了，此时vsftpd只能监听到IPv4的FTP请求，不能监听到IPv6的FTP请求。怎样让vsftpd同时支持IPv4和IPv6哪？经过测试发现只要把'/etc/vsftpd.conf'配置文件中listen=YES"注释掉，，"listen_ipv6=YES"开启，保存配置文件。
1 root@dimon-HP-dx2718-MT-KM255AV:/home# cat /etc/vsftpd.conf 2 # Example config file /etc/vsftpd.conf 3 # 4 # The default compiled in settings are fairly paranoid. This sample file 5 # loosens things up a bit, to make the ftp daemon more usable. 6 # Please see vsftpd.conf.5 for all compiled in defaults. 7 # 8 # READ THIS: This example file is NOT an exhaustive list of vsftpd options. 9 # Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's 10 # capabilities. 11 # 12 # 13 # Run standalone? vsftpd can run either from an inetd or as a standalone 14 # daemon started from an initscript. 15 #listen=YES 16 # 17 # Run standalone with IPv6? 18 # Like the listen parameter, except vsftpd will listen on an IPv6 socket 19 # instead of an IPv4 one. This parameter and the listen parameter are mutually 20 # exclusive. 21 listen_ipv6=YES 22 # 23 # Allow anonymous FTP? (Disabled by default) 24 anonymous_enable=NO
然后重启vsftpd service，重启完成后vsftpd就可以同时监听IPv4和IPv6的FTP请求了。
1 service vsftpd restart
我PC的配置是X86, Ununtu14.x, vsftpd的版本是vsfptd-2.3.5
