[expert] Pauses with FTP and POP3
I have a new Mdk 8.2 server that is handling FTP and POP 3 services, the initial connect takes a very long time, up to a minute. Once the connection is made it is super fast, but it is the connection that is taking forever. Has anyone else experienced this and is there a way to tweak it? Running ProFTP for FTP and imap for POP3 on Mandrake 8.2 on an IBM Netfinity Server. Thanks, -Scott Want to buy your Pack or Services from MandrakeSoft? Go to http://www.mandrakestore.com

Short answer: Sounds like a DNS (Name Server) problem. Check your DNS setup.

Should I be using caching nameserver on this box? It is not hosting DNS. At 12:42 PM 7/24/2002 -0700, Tibbetts, Ric wrote: >Short answer: >Sounds like a DNS (Name Server) problem.

What is happening is the server on your machine is doing a reverse lookup on the IP address of the machine that is connecting to it. Do you understand what the problem is? The problem is only partially able to be fixed by a proper dns configuration on your part. The other part is that someone else's DNS out on the internet can be royally screwed and you will still see the delays. But that doesn't sound like your problem. It sounds like you are having problems with reverse lookups from local connections. You should have a DNS server setup on your local lan that is authoritative for the domain name you are using *AND* the local IP subnet (reverse). So if you were using *.domain.com and 192.168.1.*, then your dns server should be authoritative for domain.com and 1.168.192.in-addr.arpa. > It is not hosting DNS. What are you using as a DNS source? Your ISP? Where is the connection originating from? What's their IP address? The answers to those questions provide a lot of direction to the one answer that will solve all of your problems.

I do understand the host look up delay. Explains why Apache has host look up off and responds instantly. > But that doesn't sound like your problem.

The slow response is any connection inside the network and out. I can send you the IP address if you would like to see the delay yourself. I have the two domain servers for the network is resolv.conf, they are the authority for the network. > What are you using as a DNS source? Your ISP? Where is the connection > originating from?

I am converting several BSDI boxes over to Mandrake for production use. The two DNS boxes are still running BSDI, but are functional.
