FTP Slow

[beasolutions]

We're running a couple of Plesk 9.2.1 Containers in Ubuntu, on a Virtuozzo 4 box running Fedora.

Users are reporting that FTP into the containers is generally very slow.

Does anyone have any suggestions as to what we can do about this?

Thanks,

Marc

Hello Marc,

Most probably the reason of slow FTP login is reverse-lookup problem. When people connect your server by FTP, your server tries to do reverse lookup of hostname's IP. In case of problem with DNS settings it can lead to connection timeout.

So, make sure that your server's hostname is resolved to the right IP and this IP can be back-resolved from the Parallels Plesk server.

Please, check the following article for more information:

in your domain name servers (dns settings) do the following:

somedomain.com. NS your.ip.adress-in-reverse-here.in-addr.arpa.

this will speed up your look up. it will take about a week to propigate

We found our issue was in fact that there were no ports open for passive FTP in the firewall. We added TCP 49152-65534 incoming to the firewall rules, and added this to the ProFTPd configuration.

This solved the problem.
