Description of problem:
It takes an extremely long time to download files using the FTP client on
my RH7.2 machine, even from computers on our LAN. This is an intermittent
problem occuring more that 50% of the time.
I didn't have this problem with RH7.1. This may be related to my NIC, a
CNet PRO200(B), that should be using the dmfe driver.
For my latest example of this problem, I rebooted to see if I could get
the problem to go away. ifconfig currently shows a high number of errors
on the RX packets line for eth0 (text copied by hand):
Link encap:Ethernet HWaddr 00:80:AD:76:78:8D

Steps to Reproduce:
1. ftp wolf (Solaris 2.6)
3. mget file*
4. wait several minutes
5. respond "y" to mget prompt
6. Go to alternate character-mode console and watch download progress.
Wait several minutes before file starts downloading.
Expected Results: I don't usually experience long wait times in steps 4
and 6 above.
My NIC is talking to a 3Com SuperStack II Switch 3900-36 (rev CA). I
don't suspect this has anything to do with the problem since the NIC
worked as expected under RH7.1.
By the way, my RH7.1 system had all of the latest patches, including
kernel upgrades, before I started using RH7.2 about a month ago. (And I
had a minor problem with RH7.1 when the dmfe driver was missing from one
of the kernel upgrades.) I formatted my /, /usr, /var file systems when I
installed RH7.2, but I kept the data on the /home file system.
What kernel version are you using now, and what was the last working
kernel version you had with 7.1?
My apologies. I remembered after I submitted this report that I had also
changed the computer, but kept the same NIC. And thanks to your question about
the kernel, I would tend to believe that my problem is hardware related. The
old 7.1 kernel was 2.4.9-12 (i586) and for 7.2 it is 2.4.9-13 (i686). (The old
computer had a 120 MHz Pentium and the new one has a 233 MHz Pentium II.) I
have also compiled the 2.4.16 kernel and it is giving me the same poor results.
Please close this report. If I can, I'll experiment with other computers and
versions 7.1 and 7.2. If I find a real problem, I'll report back.
