Description Karen 2002-07-01 18:22:46 UTC

From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0)

Description of problem:


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. ftp a file from this box to another Linux box
2. ftp a file from this box to another HP box
3. ftp a file to this box from either above. All Linux builds on IBM xseries 
rack mounts are behaving the same.
	

Actual Results:  The ftp works but it takes a couple of hours for just a 500MB 
file.

Expected Results:  Should happen pretty fast.

This can have a number of reasons, and wu-ftpd isn't likely to be the culprit. 
It is much more likely that the driver for your network card isn't performing 
well. 
 
- What network card are you using? 
- Does the same happen if you use "ftp localhost" to download the file?

Comment 2 Karen 2002-07-02 13:57:28 UTC

This is a standard integrated adapter on the IBM xseries 330, 10/100 Mbps. I 
tried to ftp to localhost and it does seem to be fast.

How do I tell what driver it is using?

Thanks

Comment 3 Bernhard Rosenkraenzer 2002-07-02 14:02:34 UTC

You can tell which driver you are using by looking at the output of lsmod. 
It lists all currently loaded kernel modules [mostly drivers]. 
 
Since ftp localhost is not affected, this is almost certainly driver related; 
changing component.

Comment 5 Arjan van de Ven 2002-07-02 16:21:36 UTC

What kernel version are you actually running? If it's not 2.4.9-31, 2.4.9-34 or
2.4.18-5, please upgrade to that first since that has a bugfixed eepro100 driver.

Comment 6 Karen 2002-07-02 19:02:06 UTC

I am currently at 2.4.2-2. I'll try upgrading and see if that fixes. Thanks!

Comment 8 Karen 2003-01-28 22:06:18 UTC

Found the problem! Slow ftp caused by the ethernet switch being set to 
autonegotiate, while the Linux server was set to 100FD. Did a # mii-tool eth0 
to find the correct speed of the NIC.
