Ever since the upgrade to CentOS 5.4 the system boots extremely slow and x-windows is virtually unusable unless the machine is connected to a network. It hangs at netstat, cups, httpd during the boot process. I utilize the operating system to create Asterisk servers and sometimes they are not connected to a network ever.

But I clean my PC every few days "BleachBit"
I have read some where on the magazine Network receiving suppose to be higher. so how can I fix this issue please i am having allot problems, u use cable from Comcast
I am not quite sure what Information you might need from me to give.
I use Ubuntu 8.04 LTS
I have recently moved countries and have finally got my internet connected today after a lengthy wait. I have a pretty fast connection - it's a fibre connection at approx 100Mbps Between my onu (modem) & computer (Lenovo SL510) I have a cisco wrt120N wireless router. I'm using Opensuse 11.3 (also dual boot with Win7)
My problem is . . . When I enter url in firefox (4) I get the message "looking up www. . ." for approx 5 to 15 seconds before anything starts to load. I also have the same behaviour in konqueror, firefox and yast software manager.
If I use Google Chrome the pages load instantly. Even never before visited pages.
A typical webpage such as Stuff.co.nz - Latest New Zealand News & World News, Sports News & NZ Weather Forecasts takes approx 20 to thirty secs to load in firefox and 3 seconds in Chrome. I can see the same behaviour always whether Chrome used first or firefox used first - so cache does not appear to be the issue.
If I boot into Win7 - websites load instantly there also.
I have updated to the latest wireless drivers for my system - but the behaviour is also evident if I attach a lan cable.
Here is a little info
Code:
/sbin/ifconfig

It may have something to do with my recent installation and removal of tor, but I can't narrow down when exactly it began. I'm getting no better than about 5000B/s download rates for apt. This means just a download of the package list takes a good 5 minutes. Other networking seems to run fine, but synaptic and apt are crawling.
View 5 Replies View RelatedI have a strange problem that I cannot diagnose -- slow wifi. About two or three weeks ago, I noticed that my wifi began to slow down dramatically. The problem is the same on my ubuntu laptop and my ipad. But when I connect directly to the router with a network cable, my connection is fine. So it is definitely a problem with the wifi signal itself.
What I have done so far:
(1) I checked all of the MAC addresses connected to my wifi. I identified my tivo box, laptop, and ipad. Nothing else.
(2) I used [I]wifi analyzer[I] on my android phone and selected an unused wifi channel (channel 8).
(3) I changed the username/password on my wifi signal. I also changed the password for my router's admin privileges.
(4) I restarted my router and computer.
None of this helped.
I am using a Netgear WGR614 wireless router.
I have an adsl modem acting as a bridge to my router my setup was working well for more than year now , but then the internet went slow . I set the modem back to PPPoE the problem was with the DNS server of the ISP so using ifup i set the dns t 8.8.8.8 (google) the connection is back , but when i set the modem back as a bridge slow internet does the router know that my dns is 8.8.8.8 or i should set the dns on the router ? I can't see an option to set the dns on the router ( i just enter my username and password from the isp to use PPPoE mode ) by the way i called the isp support they kept telling me to restart , i told them i did but i never restarted my pc . I'm sure if i tell them i'm running linux they will blame the os !

Excuse my little knowledge of this stuff), before GRUB loads, is really slow. It takes about a minute to load.However, whenever I restart from my XP partition, it suddenly loads fast!

View 7 Replies View RelatedI'd like to use NetworkManager on a freshly installed CenntOS 5 on laptop Lenovo ThinkPad T61p. I followed: [URL] Everything went OK, until I selected my active LAN connection in "Edit Connections". After clicking on "Edit", it's not possible to change anything - all is grayed-out. I'm guessing it's a permission problem. But I don't know the internal structure of NetworkManager and what files to look at. I was also expecting that after stopping the network service "Syetem->Admin->Network" would be inactive, but it isn't. Shouldn't the old network manager be uninstalled as well?

View 1 Replies View RelatedWe have 2 machines (quad core intel i5) running suse 11.2. They were clean installs and both suffer from this problem on around 50% of boot-ups. Other times, the system boots quickly and is fine.
Basically, one of the CPU's gets hammered to 100% (according to KDE system monitor) for around 10 minutes after boot up. Although the other three CPU's seem mostly idle, the system is very slow, to the point of being unusable until suddenly the system recovers and runs normally.
I've looked at 'top' and the KDE system monitor and both show no process taking more than a few % of the CPU. So it is a mystery as to what is taking up so much CPU and why it does it some days and not others !
One other thing, if you try to run virtualbox during this time, it (eventually) says that the kernel drives are not loaded - so possibly the kernel is stuck loading drivers. Infact, from dmesg, I can see that the system is still booting but other than the extended time stamps, the only obvious difference between a good boot and a bad one seems to be the line :
Code:
[ 141.794727] hda-intel: IRQ timing workaround is activated for card #0. Suggest a bigger bdl_pos_adj. which is there after a slow boot. The sound works ok (as does everything else).
Not much else to say. I'd say it takes at least a minute before I get to the login screen. After that it runs fine and most of the previous problems I've had since upgrading have resolved themselves. why it's taking so long to boot up?

Is this normal? I am pretty new to Ubuntu and Linux in general.
In the right upper corner of your screen,you can see if you have a network connection or not.Most of the time I do not have one according to Networkmanager (?).So I have to enable my wired connection manually.I already tried a lot to change my settings so I would have a network connection at boot,but it doesn't seem to work....Firefox is in Offline modus when I logon..
View 2 Replies View RelatedI recently install Ubuntu-studio Desktop and some other packages. And, I upgraded my System. But since then, the Grub has started to display (I have only 9.10 installed, using the entire Disk). Also, unless I select the entry, Grub does not automatically start. The startup takes nearly 1.5 minutes. And, the Login screen, after the installation of Ubuntu Studio GDM, is much slower. I removed the Ubuntu-studio GDM package, still it takes about 20 seconds to allow me to enter Username and password. Any idea?

I'm trying to install a dual booting machine with OpenSUSE v11.1 32bit and CentOS v5.2 64bit. I installed OpenSUSE first and allowed it to install and configure grub in the MBR and after that I wanted to proceed with CentOS v5.2. The installation went fine with two notable exceptions:- when I had to configure grub installation parameters, CentOS offered me only 2 solutions: either install it on the MBR of the first hard disk or not installing it at all. Other distributions are more flexible allowing you to install it in the boot sector of the root partition for example. Because I didn't want to ruin the existent grub onfiguration, I reluctantly accepted not to install it for CentOS assuming that I could manually configure the entry later in grub's menu.lst file.
- when I was presented with the options for software components installation, I've clicked on virtualization category/function because I intend to use the machine as a VMware host. There was no guidance on screen at that point and I blindly assumed that by choosing the virtualization function I would get necessary tools and drivers that will help me further on. It seems that this was a wrong move as you can see it below.
After completing the installation, I tried to search for a template or guiding on how the menu entry in menu.lst should look like but the grub directory was empty, not surprisingly because I've told CentOS earlier not to install it. Using the files in the /boot directory from the CentOS installation I tried to improvise a menu entry but it's not working. The boot stops with famous Error 13: Invalid or unsupported executable format. Using the file command to check what kind of files I'm trying to load as kernels I'm getting :

THe problem with the debian desktop is like this: I have a TP-Link TL-WN321G installed and found by lsusb command. I make a wireless connection WPA Personal (just like the router settings) it says i am connected to the wl network but no internet connection. the route command give me this:

I tryed with wicd who said that the connection is WEP (and it's not, it is setup to WPA on the router and the network-manager conncetion) and when i try to connect i get bad password. I tryed with network-manager uninstalled and no chance.
im on node1 when i type the command ssh node2@ip the terminal hangs up a bit then an error message stating that connection timeout but here is a thing: i cant ping to node2
but i can terminate the ping manually using ctrl+c when i terminate the ping usual message appears stating 10 packets transmitted, 100% loss
ps: when i go to node3 and ssh to node2 it works fine and also i can ping from node3 to node2 very fine. and the firewalls are down at all nodes -all wired connection over a switch
Its a case of ".... wireless network connection active but still not internet connection .."I am using WEP - 128 key ... Works when I connect directly using ethernet cable ... but not wireless (pci and wireless router)

I have a laptop that came with Windows Vista (64-bit) installed. I created a new partition and installed XP (also 64-bit) alongside it.Last night I shrunk my XP partition and created another new partition and installed Linux (CentOS 64-bit) on it. I made an error in judgment and didn't allocate enough space, so I need about 10 more gigs for the Linux partition. It boots up and runs, but I need about 10 more gigs of storage for the files I want to keep on the partition (and yes, they have to be on the partition, I definitely need to know how to do this, not a workaround)I went into Vista and shrunk the XP partition by 10 gigs, so now I have 10 gigs of free, non-partitioned space.
As it stands, when I start up the computer I get the GRUB boot loader. I can boot my Linux install or choose "Other" and be taken to the Vista boot loader. From there I can choose XP or Vista to boot.So, my question is... what is the best way to append the 10 gigs of free space to the Linux partition? Is this something I should do inside of Linux? I have the option to do it in Vista, but the partition shows up as "healthy" but without a file system type.I just don't want to screw up the boot loader, partitions or anything else.This isn't my area of expertise, so if anyone could give me a good suggestion or solid answer
