This is unclear. What site(s) were used?

Provide the output of the following commands (after substituting the hostname used for the string "<hostname>"):
  • $ ping <hostname>
  • $ traceroute <hostname>
If you are unfamiliar with these commands, see their respective manpages. ping(8) will continue until Ctrl-C is pressed. Ctrl-C may also be required for traceroute(8) as well.

This doesn't make sense on multiple levels:
  • If you pinged the ftp server, why is it a private RFC1918 address?
  • If this truly is the time needed for packets to come back from the server, your response time is 5x faster than mine.

daemonfowl, it would be good if you showed the next shell's prompt. As it is, it is unclear if this is the complete output or merely cherry-picked output.

Outside of not being able to reconcile why an external ftp server would have an private non-routable address, you are presenting data which indicates that the server may be across the street. Somehow, this seems a bit too fantastic to be true...

Sir @ocicat , I'm home .. having 4 machines as a practice field .. the 2 machines I test ftp on are in 1 room even .. :-) .. I don't know what else to provide that clearifies about the problem ..

So, the ftp server is one of your local machines? If not, what is the IP address of the ftp server used?

Yes it is .. just learning by trying .. not a business or something :-)
(Router is 192.168.1.1)
The IP address of the ftp server is 192.168.1.3 and I can access it and get data .. simply it's unbelievably slow responding .

Okay, this matches the information seen in the traceroute(8) & ping(8) output -- a local network with at least one router (two LAN's...) involved. Network response appears to be as expected.

Now, back to the original question as to why ftp(1) is perceived to be slow.
  • How is the ftp(1) server configured?
  • Provide the output of ifconfig(8) for the server, & one client.
  • Assuming one system is using an em(4) interface, & the interface number is em0, provide the output of the following command:

    $ ifconfig em0 media

    Your NIC cards may have different interface drivers, so you will have to substitute accordingly.

I followed the FAQ .. login directory is /home/ftp/pub .. files chmoded as indicated and owned by root .. I have the following in rc.conf.local :
Code:
ftpproxy_flags="-R 192.168.1.3 -p 21 -b 192.168.1.1"
ftpd_flags="-DllUSA"

daemonfowl, what does simplex mean?

Thanks @ocicat !

Half or Full-Duplex is required for connection-oriented protocols such as TCP. A duplex circuit can be created by using two separate physical connections running in half duplex mode or simplex mode
Ftp relies on tcp and tcp isn't connectionless a protocol .. right? , so what's the tweak now ?

Correct, but the point I wanted you to see is that ifconfig(8) states that the connection is half-duplex -- meaning that communication is limited to one direction at a time.

Compare full-duplex.

jggimi mentioned to me another interpretation which I don't have time today to pursue.

Looool !!
well it's somehacker@ocicat@daemoforums@Gaia@MilkyWay@soon-comingBlackHole@Ragnarok .. hopefully you'll be vitharr :-) .. I do have a login named vitharr@ragnarok lol .. on a flash running puffy ..

Is there anything wrong with this :
bridge0 :
add wpi0
add bce0
up
and
bce0 set :
up media 10base2

and I connect via wpi0 using dhcp ..

Your network topology is a complete unknown at this time. No one has any clue as to what you have connected to what, why it is done as it is, & whether any decisions made here adversely affects transmission rates.

I have the suspicion that to both understand & solve this problem you need to simplify the network -- just connect the "server" to a "client" using Ethernet. As it is, there are too many unknowns involved, & you have a very bad habit of not disclosing vital information until we have beaten the problem senseless. Wasting time might be minimized if you would simply state necessary details up front. Again, the thread referenced above can serve as a guide.

One of the things you should take away from this message is that one proven technique to problem solving & troubleshooting is to simplify the problem down to the simplest configuration which still exhibits the problem. This eliminates variables which have no effect early on, so time is not wasted chasing irrelevant details. Anything you do at this point which eliminates clutter & unnecessary details will make this process go much quicker.

I removed bridge0 and related bce0 .. It's now a simple home network :

Router : 192.168.1.1
5 Machines :
Acer is using wpi0 or bce0 for wired connection (as FTP server )
As Clients : Dell/iBook/iMac/CompaqMini .. I have to use either wired connection or that Dlink Wireless Adapter ..
Yesterday I tried to ftp connect to Acer from CompaqMini using Dlink Adapter.

ok .. it seems it's not an OpenBSD related issue .. rather the cause is simply my legacy hardware/chips/Router .. lol
I tried accessing that very ftp server using Fugu (on a MacOsX tiger box) .. that was horribly slow .. I tried both via airport & wired .. so OpenBSD Rox rocks & is not to blame :-)
If ocicat can prove me wrong and offer a clue maybe .. it'll make me happier ..

I tried it the other way round , an ftp session between Mr ibook (ftp server) and Sir Acer (client) :
Code:
$ ftp 192.168.1.2
Connected to 192.168.1.2.
220 sanshiros-ibook.local FTP server (tnftpd 20061217) ready.
Name (192.168.1.2:pawaan): sanshiro
331 Password required for sanshiro.
Password:
530 Login incorrect.
ftp: Login sanshiro failed.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> ls
530 Please login with USER and PASS.
530 Please login with USER and PASS.
530 Please login with USER and PASS.
ftp> user
(username) sanshiro
331 Password required for sanshiro.
Password:
230-
    Welcome to Darwin!
230 User sanshiro logged in.
ftp> ls
200 PORT command successful.

pwd
425 Can't build data connection: Operation timed out.
ftp>
ftp> pwd
257 "/Users/sanshiro" is the current directory.
ftp> ls
200 PORT command successful.
then it keeps poor Acer waiting a while .. then a nice greet :
Code:
425 Can't build data connection: Operation timed out.
So neither wpi0/OpenBSD nor en1/iBook is the cause .. nor config .. I suspect Conceptronic router -of Jurassik Park- :-)

Now , what are a few preconditions to a fast and robust FTP server ?
Thanks !

...& since you have never supplied a network diagram, there is nothing anyone can do for you.

In case this has not been clear enough, your network toplogy is a complete mystery. No one knows what is connected to what, or can trace packets from any arbitrary computer/laptop/device to any or all other computers/laptops/devices on your network.

I have a suspicion the IP addresses used may not be all on the same segment, but no one can say with any authority because daemonfowl continues to refuse to supply a network diagram.

Hi ocicat ! (sirlessly greeting :-) )
It's a star : router provides internet access to 5 machines and Acer serving FTP access to the remaining 4 .. dhcp in all , no static IPs .
( You may suggest a particular form of network that is trouble-free as far as ftp serving is concerned .. you're welcome )
