somethign wierd happening on mandrake 10.1 official...

i have a 512k/256k adsl connection at work. when i download something via http i get decent speeds from 40 - 55kb/sec...

when i use ftp i get about 3 - 4kb/sec, now this is rather ridiculous! To test this further i ssh'd into another box on our network @ work and downloaded the same file from the same mirror via ftp and this other box was getting the file @ 50+kb/sec

on my box i get:

[root@rizon michael]# wget -c ftp://ftp.pbone.net/mirror/carroll.c...-4mdk.i586.rpm

and on the gentoo box @ work i get:

now the most frustrating part about all of this is that im trying add my contrib club mirror and i cant handle the 3kb im getting, urpmi must be using the same settings and if u compare u will see mandrake is using PASV and not PORT.

please can someoen help me fix!

if i set the gentoo box to use the PASV option with wget it also gets slow speeds so this is definately down to the system using PASV for ftp, even with mozilla firefox i get those slow speeds when downloading from ftp!!!

well I'm @ a client today fixing some windows boxes and had my pc in my car so i brought it out and tested the same thing on my clients adsl connection and i still get the same poor speeds via ftp

I'm NOT having this problem with 10.1 official.

Have you tried disabling IPV6?

Some users report a marked performance increase when this is disabled.

disable it IPv6?

Yes disable IPV6.

Nope, but please tell me how I disable IPv6, that would be very elpfull thanks!

Sigh...

Search is a marvelous thing...

and a fast reply is even more better ;-) *click*

Only for those who expect others to do their work for them....

ok well easy now, no ned for negative comments, just like you i have have helped plenty people resolving issues ok.

anyways, I took your advice and things seem to be better except i am @ home and on dialup. But im getting about 4.67kb/sec on ftp downloads which is "good" i guess. a true test will be @ work on monday when im on the adsl line. thanks for the help m8.

cheers.

For dialup that is not bad considering.

Also one IMHO mistake that dialup user's often make is to let the modem default to the FASTEST settings!!!

Sounds contradictory doesn't it?

You have to understand how the modems work though.

During connections and data transfers the modems check the quality of the lines by exchanging control test/sequences.

If your line quality degrades a bit, or is not perfectly clean initially your modem will spend most of it's time renegociating the link speed!

So it's often better to step it down to say 38k or 44k on a 56k modem, so this rarely happens.

The results are often a dramatic speed INCREASE.

for the tip amigo. I was having some wired issues copying files between mdk 10.0 and my xp mcahine.at first I thought it was samba but after doing that change the problems went away....

Gracias!!

Yeah IPV6 seems to be a real boondoggle at the moment.

I had similiar problems with Winblows machines. They would frequently be unable to resolve IP's or bring up web sites, and even then VERY VERY slowly until IPV6 is turned off.

Also under Winblows leaving IPV6 on with no local IPV6 DNS and router results in a 3-5 minute wait during XP startup for me, as the machine searches for IPV6 routers and dhcp servers.

UGH!

I though my blazing new 3.4gHz P4E system was sick...

Then I turned off IPV6 and all was fine with the world.

Ok im at work and speeds are where they should be
