CentOS 5 Networking :: Slow When Connecting To The Web (e.g. Page Loading)?

Jul 6, 2009

When running Firefox, page loading is very slow (e.g. taking nearly a minute for a ..... video to start; even gmail is slow). This is in contrast with my performance when using, e.g. linuxdcpp (file sharing), where I get speeds over 300kbps. Here is some relevant information:

[root@cgwatson ~]$ uname -rmi
2.6.18-128.el5 x86_64 x86_64
[root@cgwatson ~]$ rpm -q centos-release

Ubuntu Networking :: Slow Internet - Some Page Not Loading At All?

Mar 21, 2011

Problem with Jaunty (yes I know its old) on line. The thing is some web pages are fine and some just never seem to open up with Firefox.

I dont seem to have any problems when I attempt to ping for instance google.

ping -c 1 google.com
PING google.com ( 56(84) bytes of data.
64 bytes from ber01s02-in-f103.1e100.net ( icmp_seq=1 ttl=59


I also can open up for example, The Guardian (newspaper) home page, but when I try to open any page within the site it will try loading to no avail.

In general it seems to be almost 50% open and 50% will never open.

Network Connection type DSL
MAC address is blank
MTU automatic
IPv4 automatic (PPPoE)

Ubuntu Networking :: Page Loading Is Unnaturally Slow?

Apr 29, 2011

In ubuntu however, page loading is Unnaturally slow and "[url]...." (or whatever), returns result every 4 seconds. Strange is that Skype and online games (read HoN) work fine, with only problem is store loading 10seconds and during logging time. I will post all the command output.

sudo iptables -L -v
Chain INPUT (policy DROP 5411 packets, 658K bytes)
pkts bytes target prot opt in out source destination[code]...........

Fedora :: Firefox Very Slow Page Loading

May 5, 2010

With the last several updates to Firefox, loading pages from several different sites slows down to (slower than) a crawl - taking sometimes minutes. Most of the time, this occurs loading ads.

I don't remember what release this started with, but I didn't have problems before, and I don't have any problems loading the same web pages on IE8 (running on XP). This is the same on F12 and F11.

I have tried changing some of the securty choices, even tried blocking certain sites, but no luck.

Also, several times after a download, firefox freezes, although the rest of the desktop is okay.

Fedora Networking :: Wireless Connecting Fine But Slow Performance

Apr 29, 2010

My wireless was connecting fine, but it was impossible to browse with. So, after searching around for a while I found a thread where it said to enter this and reboot.
#echo "net.ipv4.tcp_moderate_rcvbuf=0" >> /etc/sysctl.conf
#echo "net.ipv4.tcp_default_win_scale=0" >> /etc/sysctl.conf
But after entering that and re booting, now I cant even connect to the wireless. It says connecting but times out.

Ubuntu Networking :: Slow Download Speeds And Isn't Connecting To The Internet

Aug 27, 2010

I've been using Ubuntu for a while (though I would not consider myself an "expert") and have just gone back to school. I live on campus and connect to the network through an ethernet cord. On Windows, the download speed is 1 Mb/s by default, but if you go through and configure the network card (turning off the auto-negotiation and setting the speed to 10, duplex full) the download speed will increase to 10 Mb/s, a considerable difference. So, I tried to do this in Ubuntu by opening the terminal and typing the following:

sudo ethtool -s eth0 autoneg off speed 10 duplex full and all of a sudden, my computer isn't connecting to the internet. When I type: sudo ethtool -s eth0 autoneg on it suddenly starts working again.

Ubuntu Networking :: Slow Loading / Access Of Sites Using Https?

Jul 8, 2011

I'm on Ubuntu 11.04 and have wired internet connection.

Some sites (particularly https) take very long time to load . Sometimes I get "Page is taking a long time to load . Reload the page later" message.

Now , this is happening for some http webpages also.

This is not a problem with browser.

I have firefox , chrome , chromium and konqueror installed.

Also I can access all these sites properly from windows so it is not problem with my internet connection either.

Ubuntu Networking :: Maverick Wireless RT2800PCI - Keep Getting Disconnected And Loading Websites Is Really Slow

Nov 4, 2010

I just installed 10.10 for netbooks, and apparently it's using the RT2800PCI driver for my wireless NIC in my EeePC 901. That driver is causing havoc with my school network, I keep getting disconnected, and loading websites is really slow.

Now I know that 10.04 uses a different driver RT2860 which seems to work far better on this network.

How to change to the driver from lucid. Or does anyone know of an even better solution? I've heard rumors about something called ndiswrapper...

CentOS 5 Networking :: Internet Access Slow In CentOS 5.3?

Sep 9, 2009

I have an MSI K9A2 Platinum mobo, which has a 10/100/1000 Fast Ethernet Realtek 8111B built-in, a D-Link DIR-655 Router and a DSL modem. Compared to Windows Visya and other Linux distros ( Fedora 11, Suse 11.1, Mandriva 2009.1 ) access to the internet is much slower. It seems there is a noticeable delay when running CentOS 5.3. before internet access kicks in each time I am surfing the web or updating my system.

Is there any way I can speed things up, or determine why CentOS 5.3 seems much slower ?

CentOS 5 Networking :: Not Connecting To Internet

Feb 27, 2010

I have a CentOS server that I can connect to over my local network. The computer I'm currently on is on that same network and can access the internet. My server can not connect to the internet. The network card is obviously connecting to the network since I can access the server locally with SSH or HTTP. While in the terminal for the server, I type wget google.com and the server can not find the specified host, so this leaves me to believe it can not access the internet.

Ubuntu :: Firefox - Cannot Interact After Loading Page?

Apr 15, 2010

When I start firefox the home google page will load and all is well. When I go to any other page (ex. cnn.com, gmail, etc) the page will load graphically, but then continue to load forever. At this point I cannot click on anything in firefox including the drop-down menus.I must force quit at this point.

I updated last night even though I was already using firefox 3.6. I had a problem with flash last time I updated. I reinstalled firefox and went back to firefox 3.5 without any success.This makes me think that the problem is something other than firefox.I am on a Toshiba Satellite L505-S5965 running ubuntu 9.10. I'd give you more information but when I click on system and go down to "About Ubuntu" it loads forever - this is another problem I need to fix. Ugh. I should never have updated

CentOS 5 Networking :: Connecting Server 5.3 To DSL Router?

Sep 3, 2009

I want to use centos as a developer server on my desktop before deploying my stuff to the internet.

I have a netgear DG834G router. It's IP address on my local network is and connected to the adsl line. The router is set up to act as an dhcp server too. On the router I have reserved ip address for the nics per their mac addresses.

My server is on a dual boot desktop. The other boot is XP and works fine, picks up dhcp.

I don't know how to connect Centos to the router.

I have tried to play with the network manager but to no avail.

I can ping localhost, interface eth0 is there, but i can't ping to the router.

I have set the manager system/administration/network to get dhcp automatically.

I can't activate the eth0 although the hardware device says it is OK.

I've looked at firewall and iptalbes.

CentOS 5 Networking :: Connecting To Internet Via PPTP VPN

I am a newcommer to Centos. I should connect to internet via a pptp vpn connection. I created the connection in "network connections". In other distrows I could connect to created pptp vpn connection simply by clicking on network-manager-applet and selecting the connection, but there is no network-manager-applet in Centos. Is there any way to connect to the vpn connection I created or I should go to do it by manually editing config files?

CentOS 5 Networking :: Connecting 2 Or More Vpns From Different Isps?

May 26, 2010

it is possible to have the following network configuration: a central location called A with an ISP and two more locations (let's call them B and C) with diferent ISPs and to have a vpn connection between A and B and A and C? More exactly I have a central location with a CentOS 5.3 running as a gateway and I want to know if it's possible to have a computer from the location B and C connected to A through a VPN connection. I don't want computer from B to see the computer from C, is not necessary. What kind of equipment do I have to put in places? Routers? Managed switches? As a start I think that it have to work with a router in location B and one in location C and in location A I think that a managed switch that can manage vpns it will be ok.

Ubuntu :: Firefox The Connection Was Reset While The Page Was Loading

Mar 5, 2010

Why do I keep getting this error when I try to search something on google. It happens when my query has around five or more words. If a search for just one or two words I don't get the error. I know it's not google because it happens with bing, msn, and yahoo too. The connection was reset The connection to the server was reset while the page was loading.

* 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 surethat Firefox is permitted to access the Web.

Programming :: Loading Multiple Page Versions With PHP And MySQL?

Jun 18, 2011

I have a page which is going to be internationalized, and available in more languages. It contains PHP scripts to load, let's say, current user's data from database and the internationalized content itself, like "Welcome user" message. The problem for me is the fact, that internationalized content is not continual, and it's all over the page mixed with php scripts.

I don't want to use eval(). I've got 2 , they are, however, not good enough. 1. One file per language version, with scripts included - there will be many languages, so there would have to be many files with redundant data. Also if I wanted to change structure of script, I would have to change it in all pages. 2. Load international data from db, while scripts are on the page - not sure about good database structure I mean, how would I get the right content from database? (content would be split into rows, columns, or something?)

CentOS 5 Networking :: Qlogic 4062 Card Connecting To MSA 2312i - 5.4

Oct 27, 2010

I am trying to setup a blade server that has a QLOGIC 4062 mezzanine card to handle the iscsi traffic coming from an HP MSA 2312i SAN. I cannot seem to figure out how to get the HBA to talk to the SAN. Just to ensure the SAN was setup OK, I used the onboard netextreme NIC w/iSCSI to connect to the SAN with iscsiadm. This all works no problem. BUT, I bought the mezzanine cards to take this load of my NICs.

I know that the OS sees the two ports on the mezzanine card as dmesg shows them. This is my first time configuring a separate HBA on a blade system, so I'm kinda lost what to do with them. I have entries in the modprobe.conf file for eth2 and eth3 aliased to qla4xxx. What I am not sure about is the config for each eth2/3 device. If I ifconfig my device to the specific ip and subnet/netmask my SAN is on, I can get any response from the SAN.

Also I would have expected iscsiadm -m iface to pick up on the qlogic devices, but they don't show up in the ifaces directory. I tried to manually create an iface file for each, and it seems to be ok with that, but when I try to discover targets, I get communication errors. (I am compiling a file with all the outputs from various commands and errors, and will put them here once I have them).

What I don't understand is the process of setting up an HBA. I am quite able to setup iscsi over the regular NICs, been doing that for a while, but these HBAs have me stumped.

I also installed the qlogic qla4xxx driver and SANSurfer, but SANsurfer didn't see the HBAs. I think this was due to the age of the sansurfer software...other people have reported this as well.

CentOS 5 Networking :: Boxes Appear To Be Limited At ~10kb/s When Connecting To Any FTP Server Outside Of Our Network

Jul 13, 2010

I'm having a bizarre problem with FTP transfers from my CentOS 5.3 boxes, All of my CentOS boxes appear to be limited at ~10kb/s when connecting to any FTP server outside of our network. We have no network infrastructure which would cause this, however when I use a windows based machine it is able to connect fine.

I took my laptop running Vista, and rebooted it onto a CentOS 5.3 LiveCD, and same issue.

I have checked our iptables, cleared the rules, removed the kernel modules, checked CBQ/TC it looks like nothing is limiting this. Also, other protocols work fine. Both the windows and linux boxes used passive transfers for it.

Is there anything other than iptables/CBQ which would be on a out of the box install of CentOS I should check? Is there any kernel settings for NAT connections which may cause this?

OpenSUSE :: Fix For Firefox Acting Slow On Page Look Ups?

Mar 25, 2011

On my system Firefox 4 seemed to be taking its sweet time "looking up" addresses, but when it found the page it blazed on the render. I poked around on the net and found a few suggestions to speed up the "look up". So I thought I would share... I aimed for the fewest changes, so not to break too many things or make a big mess. (Warning moving and changing things that you don't know about, in the about:config can goof up Firefox so double check your settings) place about:config in the address bar and hit enter

You should get a really long list of things

In the search bar put

My default value was set to false, go ahead and set it to true. Right click and Toggle. Clear out the search bar where network.dns.disableIPv6 was, and put in network.http.pipelining You should have three listings Right click on network.http.pipelining and Toggle so "true" shows for the value. Next, right click on network.http.pipelining.maxrequests and Modify, a box will pop up, replace the default 4 with 8. Close the about:config

Now test your Forefox performance. These three small changes, made a world of difference for me. Its now comparably fast as chromium. If you disagree with what I did, or want to let me know of any other "safe" speedups let me know. PS. If you don't see any improvements performance-wise or your from the future and do use IPv6, it would be best to go and take these settings back to the default Firefox settings.

It is not even recognized as an adapter but when I run lspci -v it is there sure enough. When I look under the networking GUI it is listed there but it has no MAC assigned to it. Please let me know what command output you need to see and I'll get here asap. I have searched this forum and other sites and nothing so far has worked.
