I have vsftpd(2.2.2-13) configured in RHEL 6.5 for local user with the below configurations. Now while loging into ftp from linux servers it authenticates quickly, but when loging in from
windows command prompt wiht ftp it takes 30-40 seconds to login. But when I try to login usign filezilla after accepting password after 30 seconds it says the error
"Connection timed out Error: Could not connect to server" after 20 seconds. Can anyone suggest where I went wrong.



anonymous_enable=NO
local_enable=YES
write_enable=YES
local_umask=022
dirmessage_enable=YES
xferlog_enable=YES
connect_from_port_20=YES
xferlog_file=/var/log/xferlog
xferlog_std_format=YES
ascii_upload_enable=YES
ascii_download_enable=YES
chroot_local_user=YES
chroot_list_enable=YES
chroot_list_file=/etc/vsftpd/ftpusers
ls_recurse_enable=YES
listen=YES
local_root=/home/mail/
use_localtime=YES
pam_service_name=vsftpd
userlist_enable=YES
tcp_wrappers=YES

My approach would be:

• check the vsftpd logs
• check if the Linux box can resolve the hostname of the Windows box
• increase Filezilla's timeout if that's possible
• try with another client, e.g. browser using ftp:// URL or a cygwin ftp client
• run tcpdump or wireshark on the Linux server, wireshark on the Windows server to trace the packets on the connection. This looks like overkill but is actually not that hard to do and won't result in a huge amount of data if you limit the trace to packets between the two systems

My guess is that it has to do with authentication and delays related to get some information from the network. Filezilla is just a little bit more impatient than the command line client and therefore gives up.
