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
Make an alias entry for ftp
# alias ftp='/usr/bin/ftp'
To make the change permanent i.e.even after restart
# vi /root/.bashrc
Error 2:550 Create directory operation failed
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.
