What tools can I use to watch what my system is doing when it times out while waiting to log on to a website?
My Ubuntu machines are having trouble logging in to a number of external websites. Happens with both Firefox and Opera. I'll get a blank page and then a server timeout. This just started a couple of weeks ago. Before that, for a good six months, everything worked fine, and there have been no config changes other than standard patches.
Modem logs show a few dropped packets, and once a 204 error, but nothing directly associated.
CenturyLink has checked the lines and the DSL and they are fine.
Happens on two different flavors of Ubuntu (10 and 12) and two different browsers (Firefox, Opera). Doesn't happen on all websites. WordPress don't work. gMail works.
