IMPORTANT NOTE: Time out problems for telnet or ftp connection are often caused by the server trying to resolve the client IP address to a DNS name. Either DNS isn’t configured properly on your server or the client machines aren’t known to DNS. If you intend to run telnet or ftp services on your server, and aren’t using DNS, don’t forget to add the client machine name and IP in your “/etc/hosts” file on the server or you can expect to wait several minutes for the DNS lookup to time out, before you get a login: prompt.
