My problem is that all network services are slow connecting to my RH7 Linux box. (Telnet, ftp, email, etc.) For example, when I try to telnet to the box, it takes anywhere from 30 - 90 seconds to get the login prompt. Once I am logged in, the session proceeds normally. The box is also running qmail, and all attempts to send/receive email through it are slow. I have read some other posts, and get the general feeling that it might be a DNS problem. I do not run my own DNS server, I use my isp's. I have an always-on connection to the internet. Any suggestions would be greatly appreciated.
