wu-ftpd slow
 

I have wu-ftpd installed on my Redhat 7.3 box. The box sits behing a linksys router and is accessible to the web through the router's DMZ function. When I try to connect to it to ftp a file, the connection opens right away but takes 10-30 seconds to ask for the usernname. I have read several threads that point to a reverse dns lookup issue, but none of them suggest what to do to fix it. Anybody know how to fix it?

In your xinetd.conf edit the ftp service entries as follows. You can just replace your existing with the following.

service ftp
{
flags = REUSE
socket_type = stream
protocol = tcp
wait = no
user = root
server = /usr/sbin/in.ftpd
server_args = -l -a -u 002 -I
log_on_success += DURATION HOST PID
log_on_failure += HOST PID
nice = 10
}

It has to do with the HOST PID on success and Failure. I also put -I on the end of server args. This fixed it for my box.
