Fedora Networking :: HTTP Does Not Work To Some Sites?
Apr 13, 2009
I can ping certain websites, such as Adobe.com, but I cannot access them via http (i.e. through firefox or yum). Some websites work through http, like Google, while others don't. The ones that don't are always the same.
What really hurts here is I cannot yum to all repos i'd like to. Since the same sites cannot be accessed through firefox, I imagine there is some underlying problem with my system's HTTP setup.
My windows machine on the same network works fine. I have had this problem since I installed Fedora 10 about 4 months ago. I'd rather not reinstall as nothing really seems broken (aside from this http issue), my system is completely up to date.
If I use a public proxy website I can get to the sites I can't connect to directly. I've followed a FAQ from mozilla for Firefox that hasn't helped, but I don't think its a Firefox issue since yum suffers as well. I also followed the fedora FAQ and I have been using OpenDNS servers.

How do I get rid of my wubi partition since Ubuntu doesn't work on a Vista laptop. Sorry, it was a gift for Christmas. I never realized Ubuntu was so defective.I am running Windows Vista 32 bit with 3 gigs of ram and one partition from the factory (HP).

I dual boot XP and FC14 and have 2 routers. I can connect and ping one of these routers when I'm in FC and I have an IP address I just can't load any websites. When I connect to the other router (my main router) it works fine. When I boot into XP and connect to the problem router I can load pages fine. It's only when I'm on FC14 and connect to the problem router that I can't load pages even though I have an IP and can ping around.

after updating to fedora 15, the http links in Thunderbird doesn't work.I have tried many solutions, but without result.
- in prefs.js add :user_pref("network.protocol-handler.app.ftp", "/usr/bin/firefox");
user_pref("network.protocol-handler.app.http", "/usr/bin/firefox");
user_pref("network.protocol-handler.app.https", "/usr/bin/firefox");- I have tried it with KDE and GNOME.
- move .thunderbird to .thunderbird.backup and reopen thunderbird. But still same problem.
- When I create a new user it works correctly! So I think it must be related to the update.
- I also change the default application (in System Settings) to google-chrome and Opera. But no result.
- http-links in other application (dolphin, nautilus, ...) works correctly

Using netcat, nc(1), craft a valid http/1.1 request for getting http headers (not the html file itself!) for the main index page of www dot aalto dot fi. What request method did you use? Which headers did you need to send to the server? What was the status code for the request? Which headers did the server return? Explain the purpose of each header.
nc -v www dot aalto dot fi 8080
HEAD / HTML/1.1
host: www dot aalto dot fi
And it returns:
200 OK
Content-Length: 858
Content-Type: text/html

[Code]....
I really don't know what does it mean. Question 2: Using netcat, nc(1), start a bogus web server listening on the loopback interface port 8080. Verify with netstat(, that the server really is listening where it should be. Direct your browser to the bogus server and capture the User-Agent: header "Direct your browser to the bogus server and capture the User-Agent: header" I don't understand this question.

I have a question which it believe it is quite simple but I have no clue how to do it... I'm using Fedora 12 and I'm the only Linux machine in my office's LAN... I have Apache (httpd) setup and my co-workers can access the sites perfectly by using my IP address, for example [URL]... So here's the question, how do I setup a domain name so everyone in the LAN can access the sites by typing [URL]..

I have FC-4 with Squid and Dansguardian. Internet Users in my organisation are configured to use proxy with 8080 in browser IE. There's no issue with Users as DG working perfect for them. We have Business Development Team, as they need to do most of the research over internet, their IP's are included into "Exception IP List" in Dansguardian. Obviously these people will be excepted from all banned sites, BD Team able to do chat, play games and do social networking and other stuff over the net, which results in more bandwidth consumption and breaking office policies.
I have tried to implement SQUID ACL's to block few sites like " meebo.com, orkut.com,facebook.com etc" but SQUID acl's not coming into picture. any one who successfully blocked chat, banned sites and social networking in DG with my case.

I installed F14 on a friend's computer a couple of weeks ago. Today she called me saying that her ISP called her telling her they'd have to cancel her internet if she didn't fix whatever virus was sending port scans to edu domains that they'd gotten complaints from. I thought "well, there's a first"... I've got ssh to her computer, so i shelled in and ran a couple of commands, but i really know very little about how to investigate this kind of stuff.
She's directly connected to her cable modem via cat-5; but she does have a wireless card installed --she just doesn't use it, nor a router, afaik, nor as far as i'd seen when i setup her printer. I googled a bit, and ran a couple of commands, and 1 of them was interesting because it APPEARS that her wireless card is ON and the eth0 is OFF? Perhaps someone will know how to read this output better than i, and the output of the other command that i ran. Also, does anyone know any other ways to properly investigate this one? FWIW, she does use transmission to download torrents.
Anyway, here's the commands i ran:
Code:
[root@localhost ~]# ip link show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00.
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000 link/ether 00:21:97:9b:70:29 brd ff:ff:ff:ff:ff:ff
3: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN qlen 1000 link/ether 00:1e:e5:9c:b6:8a brd ff:ff:ff:ff:ff:ff [root@localhost ~]#

I have Fedora 11 and have successfully set up VNC so that I can connect within the network (direct using vnc client/server setup). I am in the middle of working on a problem and have a fried who is in another city and was trying to set up VNC so that he could connect via http, which I know is possible (that it listens on range 5800 + the display number - mine is 3 in this instance). For the life of me I cannot get the java http viewer to work, here is what I have done so far: My vncservers file:
[Code]...
My router is set up to forward incoming requests on the range 5900-5910 and 5800-5800 to this computer. I have opened ports 5902, 5903, 5802, and 5803 on my linux firewall. So far as I know, this is all that is necessary..well. Whenever I attempt to connect via [URL]:5803 I get a time out error. What could be wrong?

Ive heard so much about linux and while it is great to be back online it is frustrating when certain sites and applications dont work with linux. Why cant linux produce a simple o/s like windows where i can download a file and open it simply without having to type and search.
I dont want to give up on ubuntu but unless i can get freecorder working or the sound recorder to actually record by itself or with audacity and tvu player and andromedanet.com to work hen i will have to, but my question remains- why cant linux be so user friendly to pcnumbnuts like me and others and perform simply and then you would have a real alternative to windows, but until then windows wins all time bye all.

What I want to do now is make nicmatthew.co.cc point to /var/www/nicmatthew/html and make rielworld.co.cc point to /var/www/jimriel/html. I have created the apache vHosts nicmatthew.co.cc and rielworld.co.cc containing this:
Code:
<VirtualHost 67.23.224.90:80>
ServerName nicmatthew.co.cc
ServerAlias nicmatthew.co.cc
ServerAdmin nmatthew@nicmatthew.co.cc
[Code]...
So now I would like to know how to make rielworld.co.cc and nicmatthew.co.cc point to the correct places. Do I somehow set up nameservers? Do I make an A record?

In the past week or so I've noticed some weird network behaviour. I find accessing some sites such as Amazon, Paypal, and Bigstockphoto really slow. Sometimes the page will not load at all. Other sites are fine. The problem sites are not a problem for others on my LAN at home. When I try to open the problem sites, I can see in Firestarter blocked connections coming from 2.1(8/9).xxx.xxx on various ports such as 36007. This only happens for the problem sites. I attached a typical output from firestarter.
This happens with Firfeox or Chrome. Using Ubuntu 10.10

I have searched and searched for a reverse proxy solution for non-website traffic. TCP but not http, on ports other than 80, 443, 8080, etc. Basically I just need a TCP forwarder that works with multiple TCP servers, WITHOUT webpage caching features. I do not need or want any webpage caching. Can squid work as a reverse proxy for TCP traffic without http? The other program I came across in searching was HAproxy. Both programs are for http but I am curious if they would work for TCP servers that do not serve webpages.

I installed Nagios on my Ubuntu 10.04 server using apt-get and when I accessed the web console, everything was OK. I made some changes to apache (creating some new virtual sites) and since then Nagios gives me a warning message for HTTP with the message, HTTP WARNING: HTTP/1.1 404 Not Found. The sites that I created are working perfectly. I noticed that the attemps are 4/4. Does this need to be reset or does Nagios automatically reset that once it detects the issue is resolved?

I am running Ubuntu 9.04 32bit on a dual boot (XP) computer. No internet problems in windows, and I am currently typing this post on my wifes HP laptop running 9.10. I have no browsing ability on the desktop running 9.04, and updates don't work (in details, every other line fails) But, I can bring up Google, and search it, pictures and all, but cannot go to different sites (ebay, hotmail, amazon as the first few i try). Also, my pidgin works fine, as I am talking on it now. I have tried to turn off ipv6 in Firefox and ubuntu, neither doing anything noticeable.

I have an odd Linux problem. Changed ISP recently -- Windows NT4 & W95 work fine. Linux has worked fine on previous ISPs, but on the newest ISP, I can connect successfully on Linux, but can only communicate w/maybe one out of 10 sites (Google, for ex.). Mostly I get "cannot connect to site". Some points:
-Linux is Slackware w/kernel build 2.4.26.
-No settings changed from Linux setup that worked fine on previous ISPs.
-/var/log/Log file says PPP connects via CHAP successfully & no problems..
-I don't see any similarity on the few sites I can connect to -- seems random.
-ISP is useless -- say they "don't support Linux".
-Using Firefox & Konqueror browsers.

I need to block some websites and torrents on my LAN running on mostly WIndows XP pcs and a Windows 2008 domain controller. It's possible to block some sites using DNS in Windows Domain controller, but users have the rights to change DNS and bypass the rule. Editing HOSTS file doesn't workThen I tried using Avast antivirus Site Block feature, but that doesn't work on any browser except Mozilla. We have to use Epic and Mozilla Firefox.We can't use a dedicated hardware firewall due to budget constraints and the fact that we have multiple ADSL lines for internet. No single gateway.

I just setup a linux machine that act as a gateway along with squid running in transparent mode. Now I have one asterisk server which is behind that gateway I mean on my local subnet which pass through my linux gateway. Voip server having 4mb up n 4 mb down limit. Clients having 512kbps and upload 2mb.
Linux gateway : controlling band width of each clients
Squid acl forNAT issue with voip sites
Now my question is regarding skype calling. Since skype uses port 80, does it mean that it passes its request via proxy or direct and for safe side I've changed skype incoming port to 443 which squid does not see it. How much and width does skype use for calling in that case. Some one told me that it using squid to pass its request which I don't agree.

For a while now I've got a problem when surfing the internet. Everythings fine for let's say 15 minutes and then all of a sudden it takes about 1 minute to load a -random- page, once it has loaded, everthing's fine again. Transmission does not seem to have this problem. I'll double check this. Looking thru the forum I found the following "solutions". None of which has worked for me up to now:
- disable ipv6 in firefox
- set method under network manager to "Automatic (DHCP) addresses only" and use google or OpenDNS dns servers
- change resolv.conf (comparable to the second one I guess)

Strangest thing...yesterday my 11.04 box lost the ability to access anything external. I can ssh to the box from outside my network, and all other boxes on my network are fine, but this one box can't hit anything external. If I attempt to ping a site it's doing the same resolution, but no packets are delivered.
Up until yesterday it was running fine, and I didn't make any changes to my home network or install any updates. Totally stumped.
Edit: this is a wired connection with a static internal IP.
