Thanks for your article, Alberto. http://cr.yp.to/ucspi-tcp/tcpserver.html -H: Do not look up the remote host name in DNS; remove the environment variable $TCPREMOTEHOST. To avoid loops, you must use this option for servers on TCP port 53.
I am using -H option to prevent look up remote hostname, but It takes so long time(even 70-80 sec). I tested on many remote host with different ISP. but result was same. I have managing another server with same debian distribution and qmail. and that server is using -H option, too. but This server's tcpserver is so as fast as commercial POP server. I think I can't solve this proble with only -H option. What things are remain I have to check? ----- Original Message ----- From: <[EMAIL PROTECTED]> To: "Cho Yoonbae" <[EMAIL PROTECTED]>; <debian-isp@lists.debian.org> Sent: Sunday, April 22, 2001 9:27 PM Subject: Re: tcpserver's response time is too long.. Hello Cho, Well, i havent used so much tcpserver so -H i really dont remember what that mean. I hope that mean a non-get-canonicalname becouse just u describe (your problem) sounds as a dns problem (tcpserver is waiting for the ip-resolution and the dns-server is not responding so quick it must). I hope this help, it's just i have observed in other daemons, this could be a clue only.
