vsFTPd

Question on vsFTPd. I just switched to it from ProFTPd.

With ProFTPd clients on the LAN that connected to the ProFTPd server on the LAN had slow logins with their FTP client until in the ProPFTd config file I uncommented these two lines:

#UseReverseDNS off
#IdentLookups off

Now that I"m using vsFPTd, I was wondering if there were similar settings since I see logging into the vsFTPd server is slow (20 second delay).

Thanks

Hi,

You didn't say your distro and vsftpd version, but I'm afraid there is no such option in vsftpd, unless you're using RHEL or Centos.
Quote from this bug report:

Quote:

* the DNS reverse lookup feature was implemented without any way to disable
it. This update contains the parameter 'reverse_lookup_enable', which
allows users to enable or disable the DNS reverse lookup functionality.
(BZ#498548)

Thanks, I'm running CentOS 2.6.18 and the current version of vsftpd.

Looks like in my beginner linux experience the:

reverse_lookup_enable=NO

line that I put in my vsftpd.conf doesn't work (maybe did in previous versions?), since when I startup vsftpd I get the error:

Starting vsftpd for vsftpd: 500 OOPS: unrecognized variable in config file: reverse_lookup_enable

Does that seem right?

Hi,

I'm not running Centos, but I've tested with a friend running vsftpd-2.0.5-16.el5_5.1 on Centos 5.5 (kernel 2.6.18-164.6.1.el5.centos.plus) and the "reverse_lookup_enable=NO" option works.

Thank you for checking with your friend to see if the reverse_lookup_enable=NO worked.

Turns out I was running vsftpd 2.0.5, but I needed to run the yum update and it updated vsftpd, and now the reverse_lookup_enable=NO works.

It solved my slow ftp login problem.

Thanks!!
