Fedora :: "Unable To Access Certain Websites And Getting "unable To Find Host" Error
Dec 26, 2010
I have a lenovo x200 laptop running Fedora 14, fully up to date with the Fedora repository. Seemingly out of nowhere, some websites will no longer load. First it happened to www.facebook.com, next (after a day or so) wikipedia.org, now the Fedora forum. Other Internet access seems fine, but when I try to go to these pages I just get "unable to find host" errors. Its totally bizarre. It first happened in an airport so I thought it was just a strange network there, but now it happens at home. I can't get on these sites in firefox or elinks browsers (in a terminal) BUT I can ping both sites no problem. Also, the other computers in this house have no problem visiting these sites.

I am facing a problem concerning secure websites where I get the "Connection Reset" error in browser after a timeout of I think 1 minute.
OS: Fedora 14 ( I faced same problem with Ubuntu 10.10 )Browsers: Chrome and Firefox
The issue is not there on Windows using Chrome and Firefox so I believe this is a problem with how linux manages secure connections. I can access all the google secure websites too. There a few other websites apart from facebook.com that I know which I am unable to access.

I'm running a Fedora 10 box behind a Comcast cable modem that provides squid and mail services to 15 XP and Vista workstations. I upgraded the ethernet cards on our Fedora box to support our new 1 gigabyte network. I kept the same device configuration eth0 and eth2 by updating the /etc/udev/net persistent file and changing the ethernet hardware address in the respective ifcfg-eht files in the /etc/sysconfig/network-scripts. The box booted to the new cards, the route and ifgonfig shows the new cards and their hardware addresses, the configuration looks as how the old cards looked (eth0 and eth2 respectfully). I was able to browse the local network and have access to the internet as before from inside the network . However I cannot get access to our web server that serves our web host and our VPN services from ouside our network. I tried stopping the firewall and still could nor connect from outside the network.Could my old ethernet hardware address be hard coded somewherel?

I am unable to access wireless network from my notebook. My configuration is Dell i5, 4GB RAM and 1397 W-LAN and I have F13. I can still access Internet through Ethernet using a LAN cable but the network monitor doesn't show list of Wireless networks which my room mate's windows 7 machine easily detects.
If anyone needs more info please provide me the steps to perform to find that out

I have installed Fedora 10 and centos 5.3 on 30 system in my home office. everything works fine except accessing https websites. the problem persists in both centos and fedora even after changing firefox versions. what's worse is the problem is not resolved after changing other browsers. so the problem is not browser-centric. i think it has something to do deeper in fedora and centos. also note that i have disabled firewall and selinux but in vain. the problem is still there across all the systems. it's really a show-stopper for me.

When I try to launch something from terminal, it shows this error.
gksudo gedit /etc/hosts

My computer always had this name and I never had concerns related to his name. So, what's wrong now?

Writing a program that finds the IP address of a host name. Sorry forgot to include the line numbers, but where the $$$ is where the syntax error is. The errors are syntax error before "{" token and syntax error before "if". I've looked throught the code for a couple hours and can't figure out what's causing it. The code is attached below.
#define WIN
#include <stdio.h>
#include <stdlib.h>

I'm currently running 11.3 and decided I'd try upgrading to 11.4 following the instructions here: SDB:System upgrade - openSUSEUnfortunately, my attempts are defeated at the point of trying to refresh the new repos; I get the following message (for the oss repo, in this case):
Download (curl) error for 'url':
Error code: Connection failed
Error message: Couldn't resolve host 'download.opensuse.org'
With 11.4 replaced by 11.3 in the repo url, it refreshes just fine. The only repository that works when I change 11.3 to 11.4 is the Packman repo. I'm not really sure why the connection fails for 11.4 but not 11.3!
Further info: I have an old router with no IPv6 support, but have IPv6 disabled system-wide. I can enter the url for the repositories into firefox and they come up just fine - it's only with zypper/YaST that I get the above error message.I also tried upgrading using the network CD but ran into the same sort of problem. In this case it may be because the CD installer doesn't disable IPv6. (I didn't want to download the DVD at my connection speed, and the KDE live CD is not listed as suitable for upgrade).

I have a box (boell) running Fedora 10 sitting behind a firewall at school. I am able to freely ssh to and from this box to other computers (minion) within that lan. Outside of this network I cannot directly ssh to boell - I must ssh first to minion, then I can ssh to boell. I've spoken with the sysadmin and he's verified that the firewall permits ssh freely - i haven't had any issues like this with other boxes of mine there, so this isn't any surprise.
I have verified that the hosts.deny file is blank, iptables permits ports 22 (and 80) and I didn't see anything obvious in the sshd_config. I tried a tcp dump on the external host and boell while attempting to ssh from the former to boell. The packets appear to be acknowledged by boell, but this fails to lead to a connection. I've tried this process with external hosts in different locations with the same result. I have made few modifications to the default installation for F10, so perhaps there is some default somewhere I have to change. In any case, below I have attached excerpts of germane files.
======== ssh from boell =======

I cannot install Kubuntu (or Unbuntu) 10.4 on my husband's computer. I have spent 5 hours on this and cannot get anywhere. I am deeply frustrated. The iso I burned to CD is good (works on 2 other computers). His computer will not boot from USB, no matter what I do to the drive order in BIOS. After loading the blue screen with the Kubuntu logo on it (and the blue-white dots), the screen changes to black and shows the following text:
BusyBox v1.13.3 (Ubuntu 1:1.13.3-1ubuntu11) built-in shell (ash) (initrafs) Unable to find a medium containing a live file system.
He really needs to get rid of WinXP. Kubuntu is what I have on my computer (and love it!). Here is some info about his computer:
OS Name Microsoft Windows XP Home Edition
Version 5.1.2600 Service Pack 3 Build 2600
OS Manufacturer Microsoft Corporation

Attempting to use PLACES>Home (or Documents,Bin,Desktop,etc.)brings up the error message "There is no Windows program configured to open this type of file." If I open Open Office I can find all files in home, documents, etc. and open them.The computer is otherwise functioning normally but using the usual methods all the files that should show look empty. How did this happen? I was attempting to use WINE to load Avery Wizard (a Win utility) through AWsetup.exe. To do this I changed permissions for that file but I have subsequently removed the file and its subfiles using the terminal.

I can ping a host on my LAN successfully, but I cannot ping [URL]... for example. I have disabled the firewall and set http_proxy and can browse the internet with "Use system proxy settings" checked in Firefox. I am unable to update with yum either, but I am not sure if this is a side effect or not. I have run a trace on my ip address as I am browsing the internet and I can see the sites I am visiting on our web appliance. However, if I try to ping or update no requests are hitting the proxy so I don't think that is the issue.

I have a weird problem with opening certain websites under ubuntu. I tried at windows and i have no problem. The DNS in windows is my modem 192.168.1.1 but under linux for some strange reason this won't fly.For example ......com won't open on firefox, but ping and traceroute works just fine.
UPDATE: ping and traceroute doesnt work for www.......com but only for [URL]After using lynx this is what i got back
Quote:
micdhack@micdhack-laptop:~$ lynx ......com
Looking up '......com' first
Looking up ......com first
Looking up ......com

Is there a way to use another dns than the one that i get from my internet provider?

I'm fairly new to Ubuntu/Linux. Here's the problem I'm encountering after I tried to install Ubuntu Desktop 10.10. I was installing from a CD, as I tried to install alongside Windows XP, (The setup detected 2 hard drives, the first one was 40 GB, with all my windows stuff on it, the other was a 160 GB one), I got the message "error informing kernel about changes made to .....", which would not disappear no matter what I clicked. So, choosing the seemingly only option, I force powered down the computer. As I powered it back on.
Windows did not boot, instead I just got a black screen of nothing but a flashing _. I tried booting from the LiveCD again, which worked well enough, EXCEPT, the 40 GB hardrive full of my Windows stuff and files was not detected, and the 160 GB drive was detected only in the drives tool, but not accessible. I have no clue as to how to: 1. retrieve important files from my 40 GB drive. 2. Restore Windows XP professional.

I've got a problem with 'seeing' other machines on my Network. I have two laptops both with F10 on them however I can't ping either of them. They can connect fine to the internet and ping the router, they are both on the same subnet with Firewalls disabled on both machines. When I try to ping it says: "Destination Host Unreachable". I've tried firing up Wireshark to see if that will give me any clue but even that doesn't show any packets whatsoever from the other machine across the Network. It's like they are completely invisible to each other.

so I was trying to do sheduled updates on server, which is doing xen virtualization
doing kernel update (to 2.6.18-164.el5xen) i got the following error:
Running Transaction
Installing : kernel-xen [1/1]
grubby fatal error: unable to find a suitable template
and of course new kernel doesn't appears in grub.conf and don't know what is cause of this problem last kernel i was updateting in August and as i remember everything went just fine:
current kernel:
2.6.18-128.4.1.el5xen #1 SMP Tue Aug 4 21:33:24 EDT 2009 i686 i686 i386 GNU/Linux
#cat /boot/grub/grub.conf
# grub.conf generated by anaconda
[code]....
also could it be because running kernel is removed?also could it be because of LABEL entry, not /dev/... ( as i found out it was such bug, some years time ago)

When I'm trying to access my site using Firefox I get this error: "Unable to connect
Firefox can't establish a connection to the server at mysite.com.
-The site could be temporarily unavailable or too busy. Try again in a few moments.
-If you are unable to load any pages, check your computer's network connection.
-If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web."
Then I tried to access my site using Opera and Chrome but I get the same error, that the browsers couldn't connect to it.
The site to which I'm trying to connect is definitely up. (I ask a few people and they can access it and I looked at [url] and it says that my site it's up)

I'm trying to make an SSH script for my place of employment. This script, I want to go out to the server hostnames we have specified (in another file) and change a users account password. We use Kerberized telnet, so if telnet root hostname fails, I want it to use ssh username hostname and use the old password (specified). If both fail, I want it to ask the user what the port should be and input the port in the ssh command.
But I'm having a issue having it try telnet root hostname and if it fails then, try to ssh in, I have no clue how to have it proceed. Is it an if statement? Here's the telnet failed message: telnet: Unable to connect to remote host: Connection refused
