Slow proftpd Connections

Just like the thread name implies, I'm experiencing about a 15-second wait after connecting to my proftpd server.

Connecting to l1.fragville.com
Connected to l1.fragville.com -> IP=69.36.35.130 PORT=21
(about 15 seconds)
Then the user information, etc.

What could this be caused by?

My proftpd.conf file:

Code:

ServerName                      "Welcome to Fragville"

ServerType                      standalone

DeferWelcome                    off

ServerIdent                    off

ShowSymlinks                    on

MultilineRFC2228                on

DefaultServer                  on

ShowSymlinks                    on

AllowOverwrite                  on

TimeoutNoTransfer              600

TimeoutStalled                  600

TimeoutIdle                    1200

DisplayLogin                    welcome.msg

DisplayFirstChdir              .message

LsDefaultOptions                "-l"

DenyFilter                      \*.*/

DefaultRoot                    ~

Port                            21

PassivePorts                    51000 51999

MaxInstances                    50

User                            nobody

Group                          nogroup

<Directory /*>

  Umask                        022  022

  AllowOverwrite                on

</Directory>

Also, for some reason, I can't follow symlinks. I can see them but I get the error:

CWD html
550 html: No such file or directory

Any ideas?

I got around this issue by mounting the directory I wanted to symlink to as a directory in the home directory of the user.

My original problem, the slow login, still exists though.

By default ProFTPD tries to do DNS and ident lookups. You can disable this behaviour by adding the following lines to your proftpd.conf:

UseReverseDNS off
IdentLookups off

Restart proftpd and you should see faster connections.
