	I haven't heard of any other complaints of this sort, and this is 
a pretty heavily trafficked machine, especially by people running 
various distributions of Linux (both being GNU code and all).

	However, if you can demonstrate the problems with tcpdump or 
other packet sniffing/capture tools, I'm sure that this is something 
they will check into.

	I'm not sure who the day-to-day administrator is for that 
machine.  I suspect you're going to have to report this problem to 
Barry Warsaw (barry at python.org), and if he doesn't have direct 
control over that machine then he will contact the people who do.

	If you don't get a reply from Barry in a couple of days about 
this issue (i.e., more than a canned auto-reply), let me know and 
I'll try to find out who the appropriate person/people is/are.
