Can't reach some valid sites via http (FC4)
From my web browser I cannot reach some sites which are quite valid (e.g., www,google,com, www,ieee,org). These come back with an "Unable to connect" page. I can occasionally get through but at least 95% of the time it fails. I can ping these sites so there doesn't appear to be a host-name resolution problem.
As some somewhat-related posts suggested I tried telneting to the hosts in question:
> telnet www,ieee,org 80
> Trying 1,0.0,0:...
> telnet: connect to address 1,0.0,0: No route to host
Later, after I managed to finally browse to www,ieee,org I repeated the telnet command. This time it succeeded with the "trying" line giving the correct IP address.
The same holds for google. One thing that both of these sites have in common is that they use a CNAME in the DNS (seen via nslookup). For google the CNAME is www,l.google,com. If I enter these directly into the browser it works though it still fails on the original (www,google,com).
I tried a couple of other browsers: Lynx (same problem) and Mozilla 1.7.8 (same problem). Oddly when I use Netscape Communicator (ancient version from 2001), it works every time; right after NS gets through I can get the other browsers to go to the site as well (they failed just before I tried it with NS). Something really quirky is going on.
My environment:
I am running Fedora Core 4 (installed over a very old RH 7.3); I haven't modified any of the netowrk setting, etc.; I just took the installation defaults (though it's possible it got some settings from the legacy installation?). My Linux box is attached to my DSL modem via a hub. I'm browsing with FireFox 1.5. I have an WinXP PC on the same hub and it has no problem finding google, etc.
