[lug] Can't DL with comcast.

[Peter Hutnick]

I just went from dialup to Comcast cable.  For some reason I can't
download any files over ~3mb.

I have gigs of disk free.  I can browse the web.  (In fact I can serve a
web site).  I can get mail with fetchmail, and send mail with sendmail
(that's right, they don't block outbound 25).

I've tried wget http, wget ftp, wget --passive-ftp ftp, mozilla http and
ftp, and ncftp.  All either won't start the download or just stop xfering
data at ~3mb.

Anyone have any ideas?  Can anyone give me any pointers on how to
troubleshoot this?

Would anyone mind looking at tcpdump output during an xfer?  (If so, what
command should I use?  I tried "#tcpdump -l not arp" but it didn't really
mean anything to me.  Honestly it looked like my system was ignoring
incoming packets from the FTP server, but what do I know?

Any pointers appreciated.  If any more info would help, let me know.

Thanks in advance for any help!

One example:

ncftp .../linux/8.0/en/iso/i386 > ls
MD5SUM                    psyche-i386-disc2.iso     psyche-i386-disc4.iso
psyche-i386-disc1.iso     psyche-i386-disc3.iso     psyche-i386-disc5.iso
ncftp .../linux/8.0/en/iso/i386 > pwd
  ftp://ftp.redhat.com/pub/redhat/linux/8.0/en/iso/i386/
ncftp .../linux/8.0/en/iso/i386 > get psyche-i386-disc1.iso
psyche-i386-disc1.iso:             ETA: 999:59    0.08/644.03 MB  311.37
