I hope you can read it carefully and be able to achieve something!

Q1) ask for help! vsftpd shows GMT time, not local time!

A) this can be solved by setting use_localtime=YES.

Q2) ask for help! Can I disable some FTP commands?

A) Yes. There are separate options (such as dirlist_enable), or you can specify the set of commands that are allowed through the cmds_allowed option.

Q3) ask for help! Can I change the work port of vsftpd?

A1) Yes. If you are running vsftpd as standalone, you can use the listen_port option in vsftpd.conf (specify the port).

A2) Yes. If you run vsftpd as inetd or xinetd, then inetd or xinetd is responsible for this problem. You will have to modify the configuration file of inetd or xinetd (possibly / etc/inetd.conf or / etc/xinetd.d/vsftpd).

Q4) ask for help! can vsftpd use LDAP server for authentication? Or use the Mysql database?

A) Yes. Vsftpd can be authenticated using PAM, so you need to configure PAM to use pam_ldap or pam_mysql modules. This includes installing the PAM module and then editing vsftpd's PAM configuration file (possibly / etc/pam.d/vsftpd).

Q5) ask for help! does vsftpd support per IP limit (per-IP limits)?

A1) Yes. If you are running vsftpd as standalone, you can use the max_per_ip option.

A2) Yes. If you run vsftpd as xinetd, you can use the configuration parameter per_source of xinetd.

Q6) ask for help! does vsftpd support bandwidth restrictions?

A) support. See the "anon_max_rate" and "local_max_rate" options in man help (vsftpd.conf.5).

Q7) ask for help! does vsftpd support IP (IP-based)-based access control?

A1) can be implemented in conjunction with tcp_wrappers (provided the compilation is supported by tcp_wrappers). Enable it by setting tcp_wrappers=YES.

A2) running vsftpd,xinetd as xinetd can be combined with tcp_wrappers.

Q8) ask for help! does vsftpd support IPv6?

A) has been supported since version 1.2.0. Check out vsftpd.conf 's man help.

Q9) ask for help! vsftpd compilation failed, error is cannot find-lcap (unable to find-lcap).

A) install libcap package and try again. It seems that Debian users encounter this problem more often.

Q10) help! My configuration file is / etc/vsftpd.conf, but it doesn't seem to work!

A) RedHat users will encounter this problem-the configuration file for vsftpd in some versions of RedHat is / etc/vsftpd/vsftpd.conf.

Q11) ask for help! vsftpd compilation failed and incomplete type (types) was reported in sysutil.c.

A) your system may not support IPv6. Either use an older version of vsftpd (for example, v1.1.3) on a modern (IPv6-enabled) system, or wait for a version that doesn't have this problem.

Q12) help! When downloading (especially a large number of small files), you see a lot of this message: "500 OOPS: vsf_sysutil_bind".

A) vsftpd-1.2.1 has solved this problem.

Q13) ask for help! can vsftpd hide or deny access to some files?

A) Yes. Take a look at the hide_file and deny_file options in vsftpd.conf 's man help.

Q14) ask for help! does vsftpd support FXP?

A) support. The FTP server does not require special configuration to support FXP. But because of vsftpd's security restrictions on IP addresses, you may not succeed. To relax this restriction, take a look at the pasv_promiscuous (and less recommended port_promiscuous) option in vsftpd.conf 's man help (vsftpd.conf.5).

Q15).

A) to learn more about vsftpd, please read vsftpd.conf 's man help and configuration
