Hi srlamb! Thanks for your response. Now here to the answers.
-
I don't know if I can ping the host, because it doesn't normally answer to
pings, either.
-
I have two
"good" and "bad" packet captures, which I've recorded using Ethereal.
Hope it helps.
-
Regarding the hub - I'll need to get a hub first. At the moment all
I have is a small switch.
-
Regarding the last packet - see my Ethereal dumps.
-
I haven't tried UDP, but I don't think there's a UDP service running on the
host. I can try asking my hostmaster to run a simple UDP server there.
-
Regarding iptables:
[root@telaviv1 ~]# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination

What is Explicit Congestion Notification?

I haven't tried "going straight to the Internet". I'm connected vis ADSL
and PPPoE. In any case, I don't think I can connect my computer to the Internet
this way for long enough in order to exhibit the problem, without neutralising
the Internet usage of the rest of my household.

I haven't tried upgrading the NAT box's firmware. However, now that I checked
there
don't seem to be any updates for it, yet.
