CentOS 5 Networking :: Internet Access Slow In CentOS 5.3?
Sep 9, 2009I 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 :: Xen - How To Remove Virbr0 Bridge
Apr 10, 2009I installed Xen package on a CentOS 5.3 x86_64. After a reboot I found the virbr0 bridge configured by default. I guess that "virbr0" is the name used conventionally by Red Hat to indicate the first bridge. In other Xen installations usually it would have named "xenbr0". I did not find in which configuration or script file it was created. How is it possible to remove that "virbr0" bridge?
View 2 Replies View RelatedSoftware :: Squid 3.0 Access List / Remove Redirect Statement From Iptables All Internet Access Is Blocked?
Jun 11, 2010I have an old FC2 box running Squid version 2.5. It has been running since 2003 so I am in the process of replacing it. I have a new machine with FC11, iptables, and Squid 3.0 installed.
On the old machine I use iptables to intercept Port 80 traffic and send it to Squid. By default I block all internet access and allow only sites that are in an Allowed_Sites.txt file. Within Squid I also have statements to allow certain users to bypass Squid based on their IP address.
I have set up the same thing on the new box. I have iptables intercepting the Port 80 traffic and sending it to Squid. That is working because if I remove the redirect statement from iptables all internet access is blocked.
The problem I am having is that Squid is not blocking any websites. It acts like the ACL is set to http_access allow all. I have worked on this for several hours and am stumped.
These are my Squid rules:
acl allowed_sites url_regex "/etc/squid/Allowed_Sites.txt"
acl manager proto cache_object
acl localhost src 127.0.0.1/32
acl to_localhost dst 127.0.0.0/8 0.0.0.0/32

Networking :: CentOS 5.5 - No Access To Internet
Oct 17, 2010I have CentOS5.5, it has full access to internet until I did something to it I couldn't figure out. This is not a cable issue since I could ping and ssh to other machines within my lan. Apache is also running fine, which is probably irrelevant. When I type traceroute cnn, it simply hangs, later saying [URL]:
Temporary failure in name resolution
Cannot handle "host" cmdline arg '[URL]' on position 1 (argc 1)
This is a desktop version of CentOS5.5, when i do Administration - Network, it says eth0 is active and Primary and Secondary DNS are set correctly to my comcast DNS server at 68.94.15x.1
CentOS 5 Networking :: Can't Ping Or Otherwise Access Internet
Mar 14, 2009I just downloaded and installed the latest Cent OS 5. I disabled SE linux, turned off the firewall, and selected the Server package options when installing. I plan on using this as a router/firewall between my internal network and the internet, as well as web server, etc. The first thing I did was to configure the two NICs, internal one with 192.168.7.1 address and the other with an address from my ISP (I have a static address, but I also tried to let the DSL router assign an address via DHCP). Everything looked fine, I checked /etc/resolv.conf and my routes. I was able to ping the DSL router from the server, but I was not able to do a ping or lookup on anything outside my network. I tried host, dig, nslookup, etc, no luck. Obviously then, I was not able to browse the net with firefox.

I can type in the servers IP address from my browser/putty/winSCP and access the server within the intranet. The problem is that i would also like to access the server using its hostname, e.g. http://centos or whatever Currently i cannot do it. I've searched the forums, edited the /etc/sysconfig/network and /etc/hosts to no avail no matter what i do i cannot access it. i've disabled some services so im not sure if this is the fault.

CentOS 5 Networking :: Unable To Access Company Vpn?
Mar 8, 2011I am trying to access my company VPN using my Centos 5.5 laptop. I have the vpn client certificate issued by my company's IT dept. I am able to access the webmail using the same certificate which I installed in firefox. But I would like to know how to use this certificate to sign in to the VPN. Some of my colleagues use the Cisco VPN client v5.0.? software and the vpn client certificate to login. It works fine. But I would like to do the same with Centos.I tried connecting using vpnc. I converted the pcf file to conf using pcf2conf. Converted the certificate to .pem file. I replaced the /etc/vpnc/default.conf file with the pcf2conf converted file.

Jan 8, 2009I can't seem to get the X server to allow access from clients on other hosts. (I know, not exactly a network problem, but. I made the change in /usr/share/gdm/defaults.conf to be : DisallowTCP=false
and this worked on another CentOS system, but it hasn't fixed it on this one. What other things could prevent other clients from connecting to the X server? From the local host, I get :
Warning: Tried to connect to session manager, Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed although the client DOES actually create the window and work! So, maybe this message is a clue.
From the remote host, I get : Error: Can't open display: 10.10.1.20:0.0 Which is not terribly informative. Is there a log somewhere which details why a connect request was denied? The files in /var/log/gdm are not very informative.
CentOS 5 Networking :: Unable To Get Internet Access To 5 Server
Jan 17, 2009I've installed centos 5 on an old computer with success and it works great.I can access the web server hosted on the centos server from any computer on the wireless and wired local network. I can also use ssh (putty) and nx client from any computer on the local network (wired and wireless) to access the centos server.On the wireless router I've configured a port forwarding to the wireless network interface on the centos server. I can access the centos server from the outside (internet) through this port forwarding both through http and ssh or nx client.MY problem is that I can't access the centos server from the internet through the wired network interface. Any attempt to view a web page or login with ssh or the nx client will timeout.

Networking :: CentOS 5.5 Box Unable To Access Live Web Service On Interwebs
Oct 27, 2010From my office and home, I can access a web service, no problem. However, from my server at the data center, I cannot. Could this be a DNS issue? I've tried with iptables enabled and disabled. selinux is disabled. This server has multiple network interfaces, one public and two private. The public has a WAN IP address (1.1.1.1), the private is 10.1.10.2 and the other private is connected via crossover cable to another server 192.168.100.1. I think route -n tells me the WAN interface is used to access the internet, as its gateway is my ISP's upstream gateway. CentOS 5.5.

Jul 27, 2010I have a Centos5.4 64bit laptop, having an eth0 and a wlan0. I connect this wired eth0 to a wall socket to access Internet via DHCP (eg the assigned address is like 192.168.192.xx). I do not have access to the ADSL router. How can I turn this laptop into a Wifi access point to allow, say my Ipad or any wireless-only client, to access the Internet thru this laptop ?
That is, communication between iPad to laptop is wifi(ad-hoc connection ??), laptop to the ADSL router is wired LAN. The laptop need to have some bridging build in ? If you can refer me some concepts, then I can follow up from there.
Or better yet, has anybody does this before ?

My VMware install went fine, config is standard settings. Now I'm trying to access the VMware Infrastructure Web Access using port 8222 (http) and 8333 (https), but it's a no go. I'm connecting from another machine on the LAN, as the CentOS box is headless. I restarted the vmware services, and they seem to be launching fine. I don't know much about VMware though. I verified with netstat and ports 8222 and 8333 are listening.
