snowwhite777 · 2010-05-12 15:46:45

All of the problem happend Suddenly!!!!!!!!

i met some problem... All of the problem is not appear in Windows

1. I cannot get on the internet by proxy... I try firefox, google-chrome, konqueror, all of them
cannot, but opera can. I dont' do anything even upgrade my system.

2. Even if I don't use the proxy, a lot of website is not allowed to explore, for example: ebay. all of the browser cannot, but opera can....

3.when I pacman -Syu, it will appear some error:

error: failed retrieving file 'community.db.tar.gz' from ftp.tku.edu.tw : No address record (no address record)

but I still can download the package and install, with poorer speed.....
I cannot use "yaourt" to visit AUR, it may display : curl error
I still can log on amsn and use bbs.

how can I fix this problem? Shall I have to paste any information needed?
Thanks for answering ^ ^

was the proxy offline, have you tried browsing without proxy, show contents of resolv.conf and route -n

snowwhite777 · 2010-05-12 16:56:34

Of course i have tried browsing without proxy, but i still cannot visit a lot of site where i can visit before these problem happended. Strangely, only opera is normal.

it seems not the problem of the proxy server and network, because all the thing is normal under windows

Here is my /etc/resolv.conf:
------------------------------------------
# Generated by NetworkManager
nameserver 163.25.114.1
------------------------------------------

and here is my route -n

------------------------------------------
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.35.0 0.0.0.0 255.255.255.0 U 1 0 0 eth0
0.0.0.0 192.168.35.254 0.0.0.0 UG 0 0 0 eth0
------------------------------------------

does it helpful?

have you check the logs for anything useful, especially /var/log/everything.log, also, try pinging your default gateway for about 2-3 minutes, check to see if the delay is always < 2 ms.

snowwhite777 · 2010-05-12 18:59:34

I have ping my default gateway , and the delay is always<2ms....
and /var/log/everything.log is too hard for me to figure out what the problem is.

try pinging www.google.com and www.yahoo.com or any other site, and show its exact output, for example timeout, or shows ip address but gets timeout etc. also9, are you the admin of this proxy? if not, did the admin make some changes to his/her config.

snowwhite777 · 2010-05-13 03:22:35

ping www.google.com
-----------------------
PING www.l.google.com (72.14.203.103) 56(84) bytes of data.

Ping www.google.com.tw
------------------------------

64 bytes from w2.rd.vip.tw1.yahoo.com (119.160.246.23): icmp_seq=1 ttl=50 time=5.64 ms

when I ping the website that i cannot visit normally
for example : ping www.gamer.com.tw
-------------------------------------------
PING www.gamer.com.tw (60.199.217.25) 56(84) bytes of data.
64 bytes from www.gamer.com.tw (60.199.217.25): icmp_seq=1 ttl=242 time=6.97 ms

I forgot to said that i cannot use "yaourt" to obtain the information of AUR
it may display: curl error

The admin may not change his/her config, because everything is good under windows in the same condition

snowwhite777 · 2010-05-13 04:04:17

when I use epiphany browser to visit website that i cannot visit normally,
it said that: Cannot resolve hostname
------------------------------------
[xyz@xyz-desktop ~]$ nslookup xyz-desktop

are those information helpful?

Sounds like possibly a dodgy DNS server... Try using OpenDNS (208.67.222.222) or Google (8.8.8.8) in /etc/resolv.conf

Also, what is the contents of /etc/nsswitch.conf

I have tried using OpenDNS (208.67.222.222) or Google (8.8.8.8) in /etc/resolv.conf
But it seems no help

Here is my /etc/nsswitch.conf
--------------------------------
# Begin /etc/nsswitch.conf

passwd: files
group: files
shadow: files

publickey: files

hosts: files dns
networks: files

protocols: files
services: files
ethers: files
rpc: files

netgroup: files

# End /etc/nsswitch.conf
------------------------------------

if it was a dns issue, you wouldnt be able to resolve the ip addresses of google/yahoo/etc. also, are u using the same ip address as the windows machine (server dhcp assigning you the same one) and do you have any iptables rules available, also, check netstat -n to see if something else is connecting to your network from ur pc and causing failures.

snowwhite777 · 2010-05-13 14:22:20

Of course i use the same ip address as the windows machine, because i install two OS in my computer.
I use state ip, not dhcp. and i don't install any iptable and firewall and netfilter.

i have checked netstate -n, there is no one connecting my network......
