suron:/home/dev/virtualftpd-6.5.8/ftpd# ftp 207.218.219.235
Connected to 207.218.219.230.
220 suron.csnet.net FTP server (Version 6.5.5 VFTPD, based on Version 6.5/OpenBSD) ready.
Name (207.218.219.230:root):

For some reason
for like 10 seconds it'll say

Connected to 207.218.219.230.

Any idea why there is a ten second delay?
(thats not the real ip)
but im just saying
That's what i get.

also
suron:/home/dev/virtualftpd-6.5.8/ftpd# nslookup mnsi.net
Server: 139.142.2.7
Address: 139.142.2.7#53

Name: mnsi.net
Address: 206.48.122.4

suron:/home/dev/virtualftpd-6.5.8/ftpd# nslookup yahoo.com
Server: 139.142.2.7
Address: 139.142.2.7#53

Non-authoritative answer:
Name: yahoo.com
Address: 66.218.71.113
Name: yahoo.com
Address: 66.218.71.112


they are instant.

How come?
suron:/home/dev/virtualftpd-6.5.8/ftpd# cat /etc/resolv.conf
search csnet.net
# ns1.broadband.net
nameserver 139.142.2.7

# Two above.net name servers
nameserver 207.126.96.162
nameserver 207.126.105.146

# Weinbar's name servers
nameserver 216.139.227.5
nameserver 216.139.227.200

Does anyone know what could be causing this slowness?

ftp'ing from other boxes there is a delay too

[billyjoe]

Thats a reverse DNS problem with the boxes that you're FTPing from. Have the person responsible for your IP addresses fix the reverse DNS.

[clocker1996]

you sure?

i nslookup'ed the ip and it returned SERVFAIL

[billyjoe]

Chuckle, your last post answered your own question. SERVFAIL means that the DNS server responsible for answering the reverse queries for your IP address isn't functioning. So basically you're waiting for the DNS lookup to timeout before it'll let you connect, thats why you get a pause.
