How do I change ppp window size in Debian?
Hi. I have a problem with my ISP's POP3 server. There is a pause between
each message as I am downloading them. Since I subscribe to quite a few
mailing lists thsi creates a lot of additional time on-line.
My ISP's support desk has emailed the following to me, though I am note
sure how to do the same thing with Debian - the command he suggests does
not work.
Here is the message:

This might be an TCP window size interaction I've noticed before between
Linux's TCP and our dialup modem servers.
Linux advertises a very large TCP window that leads to packets being
dropped in our modem servers.
After bringing up your PPP connection, try adjusting the TCP window for
that interface. If I remember correctly, on Redhat 5.2 (at least) you
do that through an ifconfig option (ifconfig ppp0 window 8000?).
Try setting it to 8000.

Cheers.
