These are some of the errors which I came across while working on FTP server along with the solutions.

**Error 1:**KERBEROS_V4 rejected as an authentication type

# ftp 10.10.10.90  
Connected to 10.10.10.90   
220 (vsFTPd 2.0.1)  
KERBEROS_V4 rejected as an authentication type

Solution:

# which ftp  
/usr/kerberos/bin/ftp

Make an alias entry for ftp

# alias ftp='/usr/bin/ftp'

To make the change permanent i.e.even after restart

# vi /root/.bashrc   
alias ftp='/usr/bin/ftp'

**Error 2:**550 Create directory operation failed

Solution:

Make sure the location where the user is trying to create a file or directory is having write permission for that user.

This error simply means the user is not permitted to create any file on the given location.
