CentOS 5 :: Can't Access Internet From Windows XP Clients / Enable This?

Jan 3, 2011

I am stepping into Linux world ...and I have chosen CentOS.
I have installed CentOS 5.5 on a dedicated IBM server successfully. My server has two network cards. I have configured eth0 for lease line internet connection with a live IP (113.xxx.xxx.xxx) and eth1 for local LAN with a static IP (192.168.0.1).

Now,
1. DHCP is working fine and I can access the server from my Windows XP clients.
2. I can access the server with SSH client PuTTY from home ( with the live IP ) and from the local LAN (with static IP 192.168.0.1)
3. I can access my shared server directory 'public' from my XP clients
4. Internet is working on sever and I have updated the server with yum update.

But, I cannot access internet from my XP clients machines.

I read "The Definitive Guide to CentOS" and tweaked the config files in different ways but it did not help. now after two sleepless nights I am here as my last hope.

I admit, I am not aware of every linux terms and commands, but I am getting into it. code...

General :: PPPOE Server Access Internet Clients Fail To Access Internet

Aug 26, 2010

I have a linux box (fedora) with two ethernet cards eth1 and eth2. On eth1 I successfully configured a PPPOE internet connection. Such that from the server I can browse the internet. On eth2 I wired it to a wireless router essentially to provide the wireless cloud. On eth2 I also configured dhcp, such that the Linux box is both PPPOE and DHCP server.However my clients on the LAN cannot access the Internet.

On passing the routing command I get
Destination Gateway Iface
196.44.x.y 0.0.0.0 ppp0
192.168.1.0 0.0.0.0 eth2 (my subnet)
0.0.0.0 0.0.0.0 ppp0.

The router (functioning as a wireless access point mainly) has a fixed IP address of 192.168.1.2 and eth2 has IP address 192.168.1.1. The dhcp file running on Linux has been set with option router (Gateway) 192.168.1.1. I cannot figure out how to correctly set the routing table such that my clients on wireless can access the internet cloud. I googled and googled but no solid solution. Any suggestions?

Ubuntu Networking :: VPN Server Does Not Allow Clients To Access Internet?

Jan 7, 2010

i have successfully setup PPTPD on my server and I can open a VPN tunnel but my clients can only ping the server's IP, they don't have access to the internet through the VPN.

i have searched different forums and understand that I have to create a route on the server to route packets between the VPN interface and my internet gateway, but I didn't manage to get this work.

here is what my setup looks like:

Code:
root@r31495:~# ifconfig
eth0 Link encap:Ethernet HWaddr 00:1c:c0:c7:13:35
inet addr:94.23.197.XX Bcast:94.23.197.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

Networking :: Set An Internet Bridge For Windows Clients?

Jun 18, 2009

having trouble connecting to many websites due to recent actions of the Iranian government on banning a lot of websites.That's why, I decided to make my computer act like a bridge for their computers, so that they can surf the web using my Internet connection in US. I have Arch linux running on my desktop. I tried to install OpenVPN based on the instructions at ArchWiki page, but I had no success. I guess OpenVPN is too much for what I want to achieve and ArchLinux repositories don't have all the necessary packages to configure it based on some posts I read.

CentOS 5 Networking :: Can't Seem To Get The X Server To Allow Access From Clients On Other Hosts?

Jan 8, 2009

I 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.

Ubuntu Installation :: Windows Clients Receive Access Denied?

Jul 20, 2010

Windows clients experience an issue of being unable to create folders inside the new share I setup. I do not want any share security on this folder since its a global share that our entire office houses client information. They can view the contents but not add it.

My smb.conf has the following settings on the share
[global]
log file = /var/log/samba/log.%m
passwd chat = *Entersnews*spassword:* %n
*Retypesnews*spassword:* %n
*passwordsupdatedssuccessfully* .

CentOS 5 Networking :: OpenVPN Multiple Servers With Clients Access

what is the best way here? I have like 5 servers, and I want my clients to access each of them, so in case 1 server is down, they can access remaining servers. Also, it will work like user1 chooses the server number and is connecting to a central database, then reply is OK, and he can connect to the server number he wished.

Networking :: Setting Up A VPN For Windows Clients To Reach Debian Server Over The Public Internet

Jan 30, 2010

I'm trying to give some windows users a permanent connection to a samba share behind a firewall over the public Internet. I know I can give them access with something like winscp (which they have done) but really I'd like to do it with a VPN so it seems seamless to the user. However I have no idea how to set up the server to support this and am finding the documentation a bit confusing. The samba share is on a Debian box and the firwewall is a Linksys WRT54GL.

Ubuntu Networking :: IP Masquerading To Enable All Nodes With Internet Access

Jul 1, 2010

I am setting up a computing cluster in my lab, as below. all the "eth0" IP addresses are static (for cluster communication) and the "eth1" of the front node is the only one connected to the internet through lab's DHCP server (which is connected to a centralized computer center in the university). The thing I wish to do is to do some sort of IP masquerading to enable all the nodes to have internet access. I actually google around and read some books. The similar things I came across is setting rules in iptables but I did not manage to get any of them working. I am using Ubuntu Lucid 64-bit on all machine.

I'm running CentOS 5.5 with a hardware Areca controller (Raid 10). I initially installed a machine and rsynced the file system to a third machine; I'm then pulling in the file system to new machines and updating grub with a script to make it bootable.

I've done this before with other machines (no raid sets) but with these machines I'm running into errors code...

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 ?

Networking :: CentOS 5.5 - No Access To Internet

Oct 17, 2010

I 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 :: Can't Seem To Access The Internet From 5.4 Server

May 20, 2011

I am using a CentOS 5.4 server for Snort (it's actually using the easyIDS config). I'm trying to modify some things, and I've noticed that I can't seem to download any files. WGET, FTP, etc... all just time out. It's not a network firewall issue, as I've been monitoring the logs and see no blocked traffic, and other machines on the subnet can get outside with no problems. I checked the Cent firewall using the setup command, and it says it is disabled as well. I'm very new to linux, so I'm wondering how I can troubleshoot this? The wget and ftp errors just say the connection timed out, but I'm not sure why.

CentOS 5 Networking :: Can't Ping Or Otherwise Access Internet

Mar 14, 2009

I 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.

CentOS 5 Server :: Allow Apache To Access The Internet?

Apr 21, 2009

We have Apache installed on CentOS 5.3 in our laboratory. Indeed the server is running fine for almost two years since it is actually the first CentOS 5 that was released just regularly updated. Now, most of our applications are custom made PHP applications and until now we somehow managed to avoid using PHP to fetch files that are on the internet itself. But now we are desperate because we need to allow PHP to fetch files through Apache but it seems as if Apache is not allowed to make a connection to the outer world. Additionally we use a proxy server to connect to the outer world so right at the beginning http_proxy is used to set that environmental variable. And for the root user it all works fine after that but it seems as if the apache user is not allowed to access the internet. Just to make a remark our web server can be accessed from the outer world so its a one way street for now.
