550 Failed to change directory from FireFTP to CentOS 5.7 VSFTPD

Postby jastanle84 » 2011/12/30 06:24:30

When trying to connect from Mozilla's FireFTP using anonymous or a FTP user on the CentOS 5.7, using VSFTPD I get the following error.

Code: Select all
550 Failed to change directory.

This is what I have in my vsftpd.conf file:

local_umask=022

# Uncomment this to allow the anonymous FTP user to upload files. This only

You don't happen to have iptables running, do you? If so, did you open up the ftp port?

The /var/ftp tree is owned by root and not ftp.
Code: Select all
chown -R ftp.ftp /var/ftp

Ok, I checked to see if iptables was running and it is not. I chowned the /var/ftp tree and now I get the following error in FireFTP:

Code: Select all
500 OOPS: vsftpd: refusing to run with writable anonymous root
500 OOPS: child died


This error happens after trying to log into anonymous and ftp users.

So perhaps
Code: Select all
chmod -w /var/ftp

May be the permissions on the /var/ftp/pub directory. I'm not very expert on vsftpd. I usually just use scp as FTP or anonymous access are not needed.

By the way - disabling the firewall (iptables) may be OK for short-term testing, but you really ought to be using it, and limiting access the minimum required hosts/ports. A subject for a new Topic if help is needed on that, after getting basic functions working.

Hi,

I don't want to retype all the things so maybe you better take a look at here where you may find the solution.



P.S.: just by the way I spotted this forum server's date - which year is it in (Posted on: 2012/1/1 4:13) ? :-)

Code: Select all
dr-xr-xr-x  4 ftp  ftp    4096 Dec 28 21:59 ftp

Any reason why this dir is not writeable (555)?

Yes, 555 is Read-eXecute not Read-Write -> 666 or RWX -> 777

chmod it with your root account to appropriate privileges that dir needs.
