Hello,

Here is the problem: I am using ppp to connect to Internet. I've recently
discovered that when I try to upload large files ( 0.1-2MB, mostly tar.gz
archives) via ftp it takes really long time. Trying the upload with the
hash marks on shows that uproximmately 50-100 K gets uploaded ( this is
how many
########################## appear) and then the transfer seems to stall.
Short files (1-50K) eventually get uploaded( albeit very slowly). The
speed of FTP downloads is consistent with what I expect (2.8-3K/sec on a
28.8 modem) during the same connection, and this happens no matter what
server I try to upload a file to.

Is this likely to be an FTp or ppp problem? FTPing from WIN95 using the
same ISP works fine both ways.

What debugging strategy would you suggest? Also-- this is something I
couldn't find from the FAQ/HOWTO/locate ppp|grep doc:
How do I find out what the negotiated connection speed has been set? (When
dialing from win, I usually get 24000 baud)

TIA for any info or suggestions. I am using the RedHat 4.1 distribution,
with no changes ( to the best of my knowledge) to relevant " factory
settings".

Best Wishes,
Andrei

I've encountered a problem quite like that. With my linux box set up as
a PPP server, I connected my Amiga computer (well, I had to try) with a
null-modem cable. The link established 100% OK, and I was able to do FTP
(and more). Here I could download at about 5-6 k/sec, but upload was
incredibly slow. So this might look like the same thing - just the
opposite direction. My guess is that the PPP parameters should be adjusted
in some way - maybe the link floods with errors, which results in
retransmissions. OK.. this really didn't help much, but I'm curious too!

Best Regards
