 |
|
I brought my desktop back from campus and I'm having a nagging problem using it on my home network, which consists of several computers connected to a DSL modem through a switch.
When I attempt to open certain sites in firefox I get the message "Connection refused when attempting to contact x.com" This only happens for certain websites google, wikipedia, some of my university's sites. I'm posting this from the computer in question and I'm able to ping all of the sites and it seems to resolve the address correctly. All other (Windows XP) machines on the network are able to browse to these sites without any problems.
Sometimes after pinging or telnetting to a server I am able to open the site in firefox. I am always able to connect to port 80 on the server using telnet. Some servers will respond normally to a GET request through telnet, but google always drops me.

resolve.conf seems right. The first address is the gateway adress and the second is my ISP's DNS server.
| Code: | # Generated by dhcpcd for interface eth0
domain domain.actdsltmp
nameserver 192.169.0.1
nameserver 216.137.64.70

I'm pretty baffled by this. I don't even know where to start troubleshooting. Please let me know if you need additional info. Any help would be greatly appreciated.
EDIT: Also, when booted into windows the machine has no such problems.
EDIT: #2 I updated everything, built a new kernel and the problem is gone. wierd.

I wonder if it could be ECN...
| Code: | | cat /proc/sys/net/ipv4/tcp_ecn |
Is is 1 or 0? If 1, try setting to 0 [zero].
It can also be set in /etc/sysctl.conf |

That's very weird. I'd suggest either your kernel or some library has a problem. Maybe you can try a new, different kernel.
If you have another machine on the lan, you can emerge squid, start it and use it as a proxy. Might help reveal some information about the problem, or at least serve as a workaround. |
