Hiya Svavar!! The problem is probably related to the fact that your workstation(s) INSIDE of your lan (on the 10.100.xx.xx network) do not have DNS entries in your DNS server... Proof is that the reverse DNS for the external world works great usually (unless you try a non-listed host behind a NAT gateway, or something similar : this should also take 20 or so seconds as well as there is no official DNS setup for this) Two suggestions: 1) Enter in your complete DNS database for all your workstations and inside hosts on your 10.100 network.. (BEST) 2) Disable Reverse-DNS lookups on the FTP server (less convenient for logging purposes - You'll only have IP addresses that you'll be forced to look up by hand if you need to.. Less secure as you won't be able to enforce Reverse DNS validation rule for logon (ie: drop any non-listed hosts/nodes that attempt to logon - only valid Internet DNS-listed hosts are granted access). So if you don't want to block anyone from your FTP server, and if you don't really need FQDN's in the log file, simply disable the Reverse-DNS lookups in the FTP server configuration. That will remove the delay. Otherwise, spend the time creating the missing internal DNS database, so that you can keep the security rules in place... Hope this helps... -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Svavar Örn Eysteinsson Sent: October 1, 2001 8:56 AM To: [EMAIL PROTECTED] Subject: RE: Slow FTP Connection? Hi. Thanks for the reply. I'm not very good at DNS so can you give me a hint. I checked the reverse address for the server in 10.100. It's : Address : 10.100.0.5 Hostname : x.internal.x.is TimeToLive : default Best regards, Svavar Orn [EMAIL PROTECTED] -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of # sriram # Sent: 1. október 2001 12:40 To: Red Hat 7. 1 MailingList Subject: Re: Slow FTP Connection? check the reverse lookup on ur DNS for this machine On Mon, 1 Oct 2001, Svavar Örn Eysteinsson wrote: !Date: Mon, 1 Oct 2001 12:35:33 -0000 !From: Svavar Örn Eysteinsson <[EMAIL PROTECTED]> !Reply-To: [EMAIL PROTECTED] !To: Red Hat 7. 1 MailingList <[EMAIL PROTECTED]> !Subject: Slow FTP Connection? ! !Hello. !I'm having a strange problem with my ftp server, not a problem maby a bug. !My FTP server is running the latest Kernel 2.4.10 and ProFTPD in Xinetd !mode. !The server has two interfaces.
