iptrace?

Thank you for the patience, Markus.

> How did you determine that this error occurred in the first place?

Connecting to many websites (google.com, what-is-what.com,
slashdot.org, yahoo.com) would be terribly slow, and often would time
out. Some images would not load as well.

Typing, for example, "www.google.com" into my web browser's address
bar. I would have to wait an exceptionally long time (30 seconds?)
before seeing any type of response. The problem is intermittent, and
not occurring now, but has been recurring for several days.

> Useful info might be, for example:
> - Which browser?

Firefox 3b5 and 3rc1, Opera 9.x, and Konqueror 3.5.9

> - Which website?

Google.com, slashdot.org, and many other large, reputable, and known websites.

This Dell Inspiron laptop is connected via ethernet cable to a Level1
router, which is connected to a cable modem, which is connected to out
cable TV provider, which connects to the ISP. Note that in my country,
the only way to connect to the ISP is either via the cable company
(cable modem) or the phone company ([a]dsl modem). We pay twice: both
the cable company and the ISP get a check every month.

> - What is the exact error message?

Standard http 502 error message for each browser in the event of
timeout, or terribly slow connection in event of connection. This is
intermittent, and not occurring now, but has been recurring for the
past few days.

> - Does it happen always?

No

> - ...

What else? Kubuntu 8.04, wired connection, no firewall, known-good
cabling (I have tested the cabling with a cable tester, and tried
replacement cabling).

Very true.

If you can be, then it will be most appreciated. Especially if you
visit Haifa and like beer :)

I set mtr to work, with no other network applications running (no
firefox, no bittorrent, no wget) and went to eat.

In Konsole I cannot simply copy the text of 'running' programs such as
mtr and top. So I took the screenshot. Static terminal applications
(apt-get, less, most everything else) I can copy.

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?
