수신 주소를 IPv6에서 IPv4로 변경

netstat -plnt체크 데몬을 사용하고 있는데 vsftpdIPv6( tcp6) 주소를 수신하고 있으므로 FileZilla를 사용하여 VM에 연결할 수 없습니다.

그러면 vsftpd수신 대기 포트를 IPv4( tcp)로 어떻게 변경합니까?

답변1

vsftpd.conf있어야 할 위치를 변경 /etc/vsftpd.conf하고 IPv6 옵션을 NO로 업데이트한 후 Yes를 들어야 합니다.

listen Yes
listen_ipv6 NO

NAME
       vsftpd.conf - config file for vsftpd

DESCRIPTION
       vsftpd.conf  may  be  used  to  control  various  aspects  of  vsftpd's
       behaviour. By default, vsftpd looks  for  this  file  at  the  location
       /etc/vsftpd.conf.   However,  you  may  override  this  by specifying a
       command line argument to vsftpd.  The  command  line  argument  is  the
       pathname of the configuration file for vsftpd. This behaviour is useful
       because you may wish to use an advanced inetd such as xinetd to  launch
       vsftpd with different configuration files on a per virtual host basis.

IPv6 모니터링

      Like  the listen parameter, except vsftpd will listen on an IPv6
      socket instead of an IPv4 one. This  parameter  and  the  listen
      parameter are mutually exclusive.

      Default: NO

듣다

If enabled, vsftpd will run in standalone mode. This means  that
vsftpd  must not be run from an inetd of some kind. Instead, the
vsftpd executable is run once directly. vsftpd itself will  then
take care of listening for and handling incoming connections.

              Default: NO
