vsftpd配合frpc内网穿透访问ftp

frp穿透内网使用vsftpd服务

1、配置vsftpd

vi /etc/vsftpd/vsftpd.conf

修改以下配置:
listen_ipv6=NO 
listen=YES
connect_from_port_20=NO

追加以下配置:
pasv_enable=YES
pasv_min_port=40024
pasv_max_port=40027
pasv_promiscuous=YES
pasv_addr_resolve=YES
pasv_address=server.chip-cloud.com
reverse_lookup_enable=NO

2、配置frpc

vi /opt/frpc/frpc.ini

追加以下配置（注意[ftp40024]不可重复）:
[ftp40024]
type = tcp
local_ip = 127.0.0.1
local_port = 40024
remote_port = 40024

[ftp40025]
type = tcp
local_ip = 127.0.0.1
local_port = 40025
remote_port = 40025

[ftp40026]
type = tcp
local_ip = 127.0.0.1
local_port = 40026
remote_port = 40026

[ftp40027]
type = tcp
local_ip = 127.0.0.1
local_port = 40027
remote_port = 40027

3、重启服务

重启frpc
systemctl restart frpc

重启vsftpd
systemctl restart vsftpd

4、查看服务状态
