Networking :: Stop "dnssearch.rr.com" Redirection While Browsing?
Jun 3, 2010
This seems to be a catch-all "... we didn't resolve your link request so we are sending you here ..." page. It lists various candidate links as alternatives to the link I was seeking. Strangly, the page often lists the exact same link that I sought in the first place. I can understand the occasional DNS lookup failure due to heavy net traffic, heavy demand for the target name serverheavy demand for a specific site link, and so on. Sadly, this happens to me at least daily and often several times every day. That hardly qualifies as "occassional" under any reasonable definition.I am in Austin, Texas -- supposedly one of the US "very wired" cities.Can anyone shed light on this happening?Is there anything that I might be doing to provoke this happening?Is Time Warner DNS in general or Austin in specific just that bad?I've tried brief experiments with other DNS servers, but they each presented their own troubles. I suspect a loose nut in the net-admin chair
This is an examination senario. We have mulitple users logging into a RHEL-4 server using putty. These people are part of a same group. They are giving UNIX shell script exam.They are helping each other copy the code by using redirection to /dev/pts/x. Is there any way I can stop this redirection?
i am using RouterTik OS as my edge router. My clients are connected to one of the lan card of this router PC. One of my client has MAC book. He can discover all the clients connected to that lan card. How can i restrict my clients unable to discover each others?
Ok, here goes, I have a rdp server sitting at a remote store which is behind a router I do not control.
I might be able to get the phone company to add routing to it but at the moment I'd like to do this with ssh and reverse port routing, because I might need this for other ports later and I never know if the phone company wont break other routings already in place or just screw up the entire thing .
I am able to have a linux box at the site ssh into a server located where I'm at and reverse port forward port 3389 to that server. I can also then ssh into that server from my linux box and port forward 3389 to my box, under another port since my 3389 is already in use. Finally I can use rdesktop to rdp on the my local box which bounces it through the server and back to the linux box which forwards it to the rdp server (A Windows 2008 server to be exact). This is all well and good and works reasonably fast, but, I need to be able to have users on windows boxes at my site do this without all of the rigmarole. I need to, I guess, redirect a normal open port, or create one, on the server where I am so that it connects internally to the reverse forwarded port or open the internal port to the outside. So I guess I need to make it a 'gateway' for that one port, this way all I have to do is point the rdp clients at the main server and port to have it eventually connect to the rdp server in the remote store.
how to go about doing it. I guess I need an iptables entry forwarding the port but I'm not sure what is should be.
The other option is opening up the port 3389 to the outside but I'm not sure how to do that either. Right now I have no iptables entries at all but even if I turn off iptables completely port 3389 is not available if I try to use it from another pc on the network but I can rdp from the server itself using the 3389 port so I know it's working internally.
There is this server where in I want to use port redirection using iptables. For port redirection I have used nat table with PREROUTING chain and REDIRECT option. Like:
Code: iptables -t nat -A PREROUTING -p tcp --dport pop3 -j REDIRECT --to-port 8110 It just does not work. I have tried to redirect other ports as well but nothing works.
I am using squid proxy server in my Linux machine for caching. Now i want run my squid in transparent mode not set proxy settings in browsers.Like squid is running port 3128. If we redirect the port 80 packets to port 3128, looping is occurred.How to avoid looping?
I have been trying to achieve something through iptables but something is going wrong. I want connection/packets arriving to a specific computer (let's call it "server") from another specific computer ("client") inside the same network to be automatically redirected to a remote computer in the internet and vice-versa. I tried doing that using iptables with these commands on the "server" PC:
I'm have a base level understand of linux at this point. I have Debian box that I am trying to do some port redirection with.
I have my external NIC as eth0 with an IP of x.x.250.5. I have my internal NIC as eth1 with an IP of 192.168.1.1.
On the internal network I have a NAS box with a web interface at 192.168.1.100. What I need is to set it up so that a request to x.x.250.5:8080 will some how forward/redirect to the internal network NAS box at 192.168.1.100:80.
I'm currently setting up a squid proxy which will be installed on a debian system configured as a bridge eth0/eth1 as br0. The problem I'm having is that port 80 requests are being proxied both ways where I only want the requests coming in via eth1 to be proxied.
Is there a way to do this? I've already tried changing the "-i br0" in the iptables redirection to "-i eth1" but no data appears to go through it.
I have a machine with two network cards running linux mint 8 XFCE (which is compatable with Ubuntu Intrepid Ibex). eth0 gos out onto the network propper, has a static IP address of 10.10.10.10 and serves DHCP requests for the 10.10.10.x subnet.
eth1 is pluged into a PPPoE concentrator, and has a static address of 192.168.0.1 (I would have left it alone but pppoeconf wouldn't work unless it had an address).
ppp0 is the piont to piont over ethernet conection that is corectly created when I run pon. I have both guard dog and guide dog installed but they are both disabled.
Now, the weird part: I can ping the IP number of the machine at the other end of the pppoe conection (when it changes I can still ping the new number), the local IPs (10.10.10.x), but *nothing* else not even the DNS servers passed to the machine during ppp conection which are in the same sub net as the machine I can ping.
When I try to ping or trace the route I get an error message like: reply from 10.10.10.10: desination unreachable There is nothing wrong with the network at the other end, as I can make an Identical PPPoE connection from other machines on the network if the the concentrator is pluged into the hub (a rather unsafe place for it to be) and it all just falls into place.
What seems to be happening is that the machine is treating eth0 rather than ppp0 as the internet gateway, and passing the packets round in circles.
I've just installed Slackware 13.1 in two different laptops for first time. I have some strange internet browsing behaviour in one of the laptops. I've installed 2 internet browsers(firefox,opera) using the directions from Slackbuilds.org and there is also konqueror pre-installed. Moreover I installed Wicd network manager.
I can browse some pages e.g. ..... with firefox very slowly but NEVER facebook. I can browse almost any page, even facebook, with OPERA but very very slowly. The same goes with konqueror... Wicd shows that i am always connected with my WPA wireless network
I have noticed that when iptables is active on my router i get a noticeable slowdown on browsing. This is untraceable through traceroute:
Code: traceroute -n www.a-site-here.com
finishes immediately and at the same time when loading the site on firefox I am getting timeouts.
I use firewall builder to configure iptables. I have removed all rules while trying to find the one causing the problem, but even disabling all rules does not solve the problem. So, by leaving only an "accept-all" rule on firewall builder(so i don't lock myself outside) I still get slowdowns. In this case
Code: iptables --list-rules gives: Code: -P INPUT DROP -P FORWARD DROP -P OUTPUT DROP
I've searched these forums as well as Firefox's site, as well as searching on Google Linux but can't find what I'm looking for.In a nutshell, I want to keep a log of my users' browser history so that even if they clear history or set Firefox to not keep history, I can still view a log of what site they have visited.My hope is that I can write a script(although I'm a BASH newb it would be a nice little real-world project for me to attempt) that would keep info such as user,visit date,ip of visited site, just the basics. A great feature would be for the logs to be emailed to me for inspection but that isn't vital if I can navigate to the log myself.
For all I know this is already available somewhere in the log folders I just can't find anything. If it helps I'm running Mint 9 Isadora and Firefox 3.6.12
Browsing via SSH Tunnel very slow When browsing in firefox at work via proxy through ssh on my 8.04 server the speed is near dial up. I have compression enabled, tried restarting ssh, and rebooting the server but it remains so sluggish. At home the connection is quick but the speed is lost in translation once I ssh in. I also tried adding "UseDNS no" to the ssh config but that did not help with the slow login or any other speed issues.
Every so often while browsing, DSN fails. The thing is that if I DIG the address at the command prompt the site immediatly pops in in Firefox. what I should do to diagnose the problem.
my computer is very slow to view regular web pages, and generally fails to load them. It seems to be a problem specifically with webpages - I can work over SSH, use email, transfer files over FTP connections, with no noticeable problems, but any regular website (including this one) can take an age to load. This happens regardless of the browser I use (at least, it happens on Firefox, Opera, and Chromium), and regardless of wired or wireless connection (though admittedly I've not tried using a wired connection very much). As far as I can tell, it can also happen on any website. It is specific to linux - my computer is dual-boot ubuntu 10.04/Windows XP, and there is no networking problem when I use Windows.
I am facing a problem in browsing website with F15 installation, both firefox and chrome browsers give me a headache. The main website that cannot be accessed is facebook.com, I only can browse it in certain of time after clearing cache, cookies and histories, this only happen for facebook web only.
I'm using wlan and I'm behind a NAT firewall. Downloading with BitTorrent can reach speeds of 1,5MB/s, but browsing is incredibly slow. Chromium/Firefox seems to hang forever on "connecting.." or "waiting for". Sometimes pressing the reload button will speed it up. I have two Ubuntu boxes and they are the same way.
I don't get it, if downloading is so fast, how can browsing be so slow. Yes I have disabled ipv6 in grub and in Firefox, don't know how to do it in Chromium. Have 64-bit Ubuntu. Cnet wlan card using rt61pci module.
Got an Edimax 7717un USB dongle for my Acer aspire 6930 (built-in WiFi is broken). It finds access point OK, but fails to setup with DHCP. If I put in manual IP config, I can ping OK, but I cannot browse web (or even my router's setup page). I get same behaviour on a home brew desktop.
With manual IP config, ping to my router works fine (and very fast, as does ping to 2 or 3 internet web sites. I can traceroute to internet web sites OK as well. With web browsing, if I wait a few minutes some bits of the page may arrive. With connection set to DHCP, Wicd shows WiFi connecting OK, but DHCP setup times out.
USB 3G Huawei E1550 modem is used for connecting to the internet.When I'm connecting to the internet modem light is blue (it means that I'm connecting using 3G network)I have issues with speed when browsing internet (using Firefox and Google Chrome) or updating software using apt-get (download speed around 1.5 - 6 kB).At the same time I can download files using Transmission with 60 - 120 kB.
HPG62-144DX notebook, Windows 7 and considering Ubuntu. I installed 10.10 and tried to get my wifi running but that wouldn't work. I had a connection only sometimes and it broke up after 5 minutes. Once I got a webpage but annoyingly slooow. Got the advice to update drivers and stuff. But the wifi connection is the only one I have...
Went back to 10.4 32-bit. Booted from CD and will keep it that way until this is sorted out. Now I see my wifi hotspots directly and I have no problem to establish a connection. The icon shows 3 bars quality. Network Tools says: Wlan1 = Realtek, Transmitted bytes xxx Received bytes yyy, no errors, link speed = 1Mbps, State = active. Looks good!
The only minor thing here is that enabling/disabling my internal Atheros antanna also enables/disables my Alfa USB Wifi adapter (based on Realtek 8187) but who cares. A bigger problem is: when I start Firefox it doesn't come up with a webpage. It just keeps on saying: "loading". At the bottom of the screen it keeps saying "Looking up" for ages. Nothing further.
I don't know if others are experiencing this but browsing is extremely slow in firefox after "upgrading" to ubuntu 11.04. I have not tried other browsers. Even checking for updates fails several times.
I had to re-boot to windows to post this thread and now it's working fine. It's been 3 days since upgrading and I've observed many times that there's no such problem in windows while I have to wait like 4-5 minutes and refresh many times to open a single page. Some sites like google are quicker though. I use firefox 4.0 both in ubuntu and windows. I didn't have this problem in 10.10 and it took me about 5 hrs. to download 1 GB upgrade packages.
I'm running Mac OS on a home network that includes a Win 7 machine and a Ubuntu box (Ubuntu 11.04 (GNU/Linux 2.6.38-8-generic i686)). Connecting to, and browsing the shared drives I have on the Ubuntu box (which acts as my server) is extremely slow from the Mac, it seems that the icons especially take ages to load. I've found a few suggestions on the net that I've implemented to no avail i.e. socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=65536 SO_SNDBUF=65536 Are there any other settings I should play with, or is there an alternative to samba that will work faster on a mixed network and be compatible with everything?
I have a desktop running Ubuntu 10.10 and several terabytes of files on it. In Windows all I have to do is enable sharing and my Mac will see the shared folders right away and I have no problem browsing them. I read somewhere that it was essentially the same process in Ubuntu which I followed but I am unable to browse. The desktop does show up in OSX but when I click on it from Finder (Path Finder actually) I get a message saying "The server "Foo" may not exist or it is unavailable at this time. Check the server name or IP address, check your network connection, and then try again."
If I select "Connect to Server" under the Go menu in finder and type in smb://ip-address then I get one step further. I am asked to log in and I just click on guest (my user name and password didn't work) and then I get a list of all the shared folders but when I click on one I get a message very similar to the one above but not identical.
Everything I have found is about 5 years old. Or has anyone had similar issues and solved them? This is the first time I have ever tried any kind of networking in Linux but I am thinking Ubuntu 10.10 may have some sort of software firewall enabled by default?
I have installed the latest released version of openSUSE, 10.3 or so, and I am having an issue getting the internet to work. The system tells me that I am connected to my wireless network, but firefox does not browse, indicating that it cannot find the network. I'm totally stumped because if my wireless network is connected, why can't I browse?
I can browse smoothly without any speed problems at all but all update stuff like apt-get , software centre etc get stuck. As in they get 0kbps fr lk a long time n then move on n then agn 0kbps. Until the downlaod is done!
Ubuntu and after installing it i can't browse any internet through firefox although ping is working good and downloading plugins to system to run MP3 or videos is also working fine but can't open any website through firefox and i tried the live cd of Ubuntu 10.4 at other PC and internet was working fine and firefox was working fine
Ubuntu but an advanced user on Windows. On my home Workgroup network, I an running Ubuntu 10.04.1 on a spare PC and Windows 7 Professional on a fast 4 core AMD PC. I built both PCs myself. The Win7 system is fully updated with maintenance. So is the Ubuntu system. The Win7 desktop system sees and shares files and printers with an XP SP3 laptop and Win 7 Home edition Netbook... and the the Ubuntu system The Ubuntu system can browse and see shares on the the XP Laptop but not the Window 7 Desktop or Netbook. Both Win7 systems can browse and share the the Ubuntu system. There are no current problems anywhere in my Windows network.
Ubuntu gets into a login loop when trying to see the Win7 systems. But before that problem gets solved.I have problem with random BSODs (00007f) on the Windows 7 systems immediately when I first try to browse the network from Ubuntu. The effect is instantaneous. You click on an icon that will browse the network and bingo the Windows system takes a BSOD 00007f dump.This appears to be something new in 10.04.1. I have loaded 8.04 and 9.10 in past just for training and and curiosity reasons and never had this problem. In the past, I lost interest and never went deeper. This time I have a dedicated PC in my network for Ubuntu and need to get deeply into Linux. I am trying to get up to speed on Linux this time around because I find that Linux systems are appearing in the network at work and I need to understand how to use and network Linux.
