I have installed CentOS on my system.When I am trying to activate internet,its not working.I tried to change the mac address to what i use for win7 but CentOS is not accepting that address.It throws error like:"unexcepted mac address".same address works fine with win7 and ubuntu.I am using cable modem for a standalone pc.
We are in the process for Integration Network with our Government Network. Let say that our network are 192.168.0.0/24 And the Government network are 10.0.0.0/8 I want to know if the local network can resolve the internet names in Government Network. I am using Bind for DNS.
I have installed CentOS in multi-boot set up.when i am trying internet thru win7,its working fine but when i am tryin to connect using CentOs,its not working.I have tried and changed the mac address to the one that is on windows(this worked fine with ubuntu) but the issue remains in CentOS.
i am unable to access internet in linux editions (redhat 5.4 & centos 5.5) recently i have taken a reliance internet connection but the think is i didn't get any ipaddress from reliance, but i accessing internet in window 7 and i have triple boot. pls any one give the solution.
I have installed Centos 5.5 on my PC and now since I am new to Linux environment I do not know how to set up Internet connection for it. I have laptop which runs on Windows and I access internet by typing in username and password for Wireless Internet (LAN cable from laptop to adapter and from adapter another cable to antenna which is outside.
I clone an drive with CentOs 5.3 from a drive connected to ATA0 device 0 of an ATA controller to an identical drive connected to the same ATA contoller ATA1 device 0. No matter what I do it boots from ATA1 device 0 and I need to be able to control which one it is booted from. When I have puppy linux on one drive and CentOs on the other drive I can control the boot thru the system BIOS either way no matter if puppy is in ATA 0 or 1. So its not a BIOS issue. It appears (to me) to be a grub configuration issue. Since the 2 drives are clones they both have VolGroup00. I think grub loads from the last VolGroup00 found.
Here is my grub.conf file: # grub.conf generated by anaconda # Note that you do not have to rerun grub after making changes to this file # NOTICE: You have a /boot partition. This means that # all kernel and initrd paths are relative to /boot/, eg. # root (hd0,0) # kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00 # initrd /initrd-version.img # boot=/dev/hde default=0 timeout=5 splashimage=(hd0,0)/grub/splash.xpm.gz hiddenmenu title CentOS (2.6.18-128.el5) root (hd0,0) kernel /vmlinuz-2.6.18-128.el5 ro root=/dev/VolGroup00/LogVol00 initrd /initrd-2.6.18-128.el5.img

I only have very basic understanding on how it works.This question may have been asked so many times, and honestly I've tried so many tutorials and have read a lot of articles but it all didn't worked. I may be too stupid to have this done, or it is just the lack of knowledge.
Here it goes,I have a VPS with a host which runs OpenVZ in LA. I want to create a VPN tunnel to the VPS and tunnel all my internet traffic to the VPS. Can somebody please help me out on the step-by-step?
I was once able to configure the VPS to run OpenVPN and my client pc was able to connect to it, but the internet connection is still thru with my local connection. Did it with a tutorial too. I would also like to ask, The VPS has 512mb of RAM, I was wondering how many clients can it handle at the same time.
I've just installed CentOS 5.3 on my laptop and trying to connect to wireless internet connection at my home but I've found no success so far. I have a key on my laptop that turns blue when wifi is activated, but it is always red in linux so I guess I need to install some drivers, but I dont know what they are. When I use Windows, it automatically turns blue without doing anything. Also, yum doesnt work as well as its not connected to internet...
I am using Centos 5. I got one error unexpectedly after some configuration for rsync and folder settings. The error i am getting is "Serve Authorization directory (daemon/ServAuthDir) is set to /var/gdm but does not exist. Please correct the configuration and restart GDM." after rebooting.
I tried to resolve the issue by setting permission for folder /var/gdm to 755. but the problem is still not resolved.
today i encountered centos 5.5 final server with a squid configured to block facebook from 9am to 4pm. i have tried to follow up the steps but am stack where time restriction is done and there is no proxy configuration done in the browser. the ip address of the server is being used as the default gateway.
What's the centos-approved way to handle group environment configuration? Let's say there are users in, oh, 4 different groups. Let's use the usual suspects:
accounting warehouse admin netadmin
and I want to set up environment variables and maybe some pathing that are specific to a given group. So that when 'joeblow', who is a member of group 'warehouse', logs in, the pathing and environment variables (and whatever else) that is needed for users in the 'warehouse' group is set up and configured.
What I was initially looking for was an /etc/groups.d, and in /etc/groups.d is
As part of the login process, the group memberships for the login username would be examined, and for each hit the respective /etc/groups.d/ script would be run. I'm not seeing anything like that, so I'm assuming centos uses some other mechanism, but I'm obviously not using the proper keyword mojo. Can someone point me to where this mechanism is described?
I am trying to install CentOS-DS on version 5.4 x86_64. I cannot get to the Extras repo due to lack of wired Internet access. I have wireless (except to server) and I have big UFD drives.
Is there any way to setup the Centos Directory Server without an internet connection?? i tried using the command: yum install centos-ds
but this just tries to connect to the internet to to download the packages. Is there a site where i can find the package so that i can copy it to my server and install it or is there some other way to do this?
I installed CentOS. NetworkManager successfully installed and launched. I can ping any IP from terminal but I can't open any site in browser except 127.0.0.1 I can't open IP of the modem 192.168.1.1 in browser also.
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 ?
I took a snapshot of my machine with internet working
If I reboot my machine I lose internet. This makes no sense to me.
I ifconfig eth0 down then ifconfig eth0 up and still no internet
Weird thing
I check ifconfig and my bcast ID is 192.168.2.255 when it is supposed to be 192.168.45.255
(When the internet is working if I check ifconfig the bcast ID is 192.168.2.255)
IF I change my bcast my internet stops working
If I reboot my machine my internet stops working
I checked /etc/sysconfig/network-scripts/ifcfg-eth0 and I see that in my snapshot (where the internet is actually working) the bcast is at 192.168.2.255
Without rebooting if I edit that script and I put it to .45.255 my internet stops working
If I reboot my machine at any time my internet stops working
I have also just realized that I cannot ping my gateway..
I have a CentOS server in one of my labs at work that does not have an Internet connection.Is there anyway that I can download the updates on a USB stick and then update the server? If so, what are the procedures?
am not able to get internet working, am using debian testing. Dunno what is the issue. Here's the lowdown on /etc/network/interfaces :-
Code: Select all# This file describes the network interfaces available on your system# and how to activate them. For more information see interfaces (8)
#The loopback network interface auto lo iface lo inet loopback
auto eth0 allow-hotplug eth0 iface eth0 inet dhcp
I tried all the usual :- Code: Select all$ sudo dhclient (this usually worked/works) $ sudo ethtool eth0 $ sudo systemctl restart networking
I have been using another OS but thought for Ham Radio Debian might be good however my stupidity took over right at the start.Have a live cd and works fine but I don't know how to connect to the Internet.Using DSL.
I've installed debian and configured the network: I do ping to the gateway and it connects, I ping one distant server directly with the IP and it can see it (but not with ping [URL]), but when I try to use internet it says that maybe the url is wrong, but it is not.
And when I try to update (apt-get update) it give me a bunch of errors : W: Failed to fetch http://ftp.es.debian.org/debian/dists/s ... elease.gpg Could not resolve 'ftp.es.debian.org' W: Failed to fetch http://ftp.es.debian.org/debian/dists/s ... ion-en.bz2 Could not resolve 'ftp.es.debian.org'
I need to shear internet i use isc-dhcp-serve and it work but internet doesn't work i have triad so many commends but still networking ... My setting is eth0 - wan eth1 -local
After doing updates to get current with Debian Jessie, I've noticed very annoying network problems going on.
This all happened while also setting up a media server box which led me to much confusion, much of what is described here [URL] ....
I've started this new thread to try to diagnose and properly take care of this specific problem alone:
Browsing the internet becomes very slow, unbearably to the point everything keeps loading up forever. This only happen while having a torrent application opened, the effects are almost immediate, closing the application and browsing resumes as normal.
How about throttling back torrent? This does not work, it even doesn't even need be at top speed. With bare minimum connections and speed will still lead browsing to a crawl.
Even so, every other device on the network is un-affected, router and other PCs continue to browse and respond very well, making it a specific on the computer in question (but also happens on my other debian jessie machine).
Can I even reach the internet? Yes I can, and this is the weird part... I can ping, solve DNS and almost everything else without issues, the only thing affected is actually browsing the internet.
I'd even setup DNS cache with dnsmasq to see if it could speed things up. Disabled ipv6, and trying pretty much every method I could find.
Having pretty much ruled out dns problems and internet connectivity, I'm at a loss for what to look for and try. Only symptom I can describe now is that the browser will start to load up webpage but never completes... but only while torrent is active.
My current setup:
I'm on Debian Jessie, a desktop with eth manually connected. Using dnsmasq for dns caching. Disable ipv6 on the network (by the way, it keeps disabling it self I dunno why).
Running KDE with ktorrent as the client. The same thing happens on my setup media box, also Debian but with deluged running instead.
Browser in question are Firefox and Chrome, both have issues with this.
Turns out it was just a setting in my own router, that apparently limits numbers of connections made, meaning while torrent is working other connections were sure dead.
But it also happens when lots of connections are being made in other ways too. The router in question is Humax HG100R-L2, provided by my ISP. The setting is in the firewall section called IP flood detection.
I rebooted my vServer (Debian 8) and it doesn't came back up. Well, I used the rescue console on my server and the server seems to be running fine, except the network was broken. So I tried 'ifconfig' but nothing came up. So I tried to enable my interface with 'ifconfig venet0 up', and now it appears in my ifconfig list
My HWaddr doesn't look that well :) 'ip addr' prints this result:
Code: Select allroot@i67svof:/var/www# ip addr 1: lo: <LOOPBACK> mtu 65536 qdisc noop state DOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: venet0: <BROADCAST,POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN
These are the last lines in /var/log/syslog:
Code: Select allroot@i67svof:/var/www# tail /var/log/syslog Feb 20 11:34:16 i67svof systemd[1]: Stopping memcached daemon... Feb 20 11:34:16 i67svof systemd[1]: Stopping Network Name Resolution...

And finally my network config in /etc/network/interfaces
Code: Select all# Auto generated lo interface auto lo iface lo inet loopback # Auto generated venet0 interface auto venet0
I'm a new Debian user but I've been around Linux for awhile. I wanted to try Debian because I wanted something stable and that I could set up myself from a minimal install. However, I'm having issues with my WiFi connection. I'm running KDE and connected to the network, but I can't access any webpages or ping, for example, google.com. I know the network is working because I'm connected to it on my phone and my wife's Macbook. Here's the output of lspci:

I'm using jessie. So far I've tried using firmware-iwlwifi from backports and installing kernel 4.3.0 from the stable repos.
