OK,
I git this problem only once in a while. Otherwise useful site that I can't access that give me "connection refused" errors when Moz or IE on a Windows box behind the same firewall as me works fine.
Here are 2 sample URLS:
http://www.mwave.com/ http://www.egain.com/
I realize that most likely these turkeys have a braindead (MS ISA? ) firewall in place. So how do I deal?
I think you may have a problem with ECN.
"Please note that kernel.org uses Explicit Congestion Notification (ECN), as defined in RFC 3168. Some broken firewalls or gateways may have problem connecting to ECN-enabled servers. Please contact your firewall or gateway vendor for necessary updates."
I had the same problem connecting to my own router through it's web-interface, thanks to ECN being enabled by default in kernel 2.6.x.
If I re-enable ECN, I can't access mwave.com either.
If I disable it again, I can.
To check your settings: cat /proc/sys/net/ipv4/tcp_ecn This will probably output: 1
To disable it, run: echo 0 > /proc/sys/net/ipv4/tcp_ecn And try connecting to e.g. mwave.com again.
To change this permanently, add: net/ipv4/tcp_ecn=0 to /etc/sysctl.conf
Regards,
Felix
