CentOS 5 :: Installing Squid Using The WCCP?
Sep 29, 2009Looking for some help getting Squid installed on CentOS 5.3 and using WCCP with a Cisco 2811 router. I think I have the port translation correct and have Squid configured for WCCP. What I can't figure out is the GRE part. Does anyone have the steps needed to configure GRE on CentOS?

CentOS 5 Networking :: How To Setup Nfs / Nis On 5.6
Jul 26, 2011my network: centos 5.6 machine, 2 disks in raid 1 client: centos 5.6 machine, 1 disk, no raid setup.the raid machine has 2 users beloning to one group (and root, with root group)
the client machine has 1 user, same groupNAME as on the raid machine. (again root, with root as group too).
where can i find the low-intelligence-level instructions for setting up nfs (the raid machine should become server) and nis (i got it is needed too).i tried some instructions from the Net (one of redhat enterprise e.g.), but after that i could mount the exported directory on the client machine, open the folder, read and copy from that folder to the client itself, but NOT write to the folder (folder with the mounted fs from the server).
CentOS 5 Networking :: Setup Two NIC's And VLAN's?
Sep 12, 2011I'm trying to setup a Asterisk box with two NIC's. The idea is that one NIC connects to the LAN on VLAN2 (for internal voice) and the other to the SIP trunk on my ISP's Cisco 1811, configured for VLAN3.
Some info: The Cisco's VLAN1 + 2 are available on my switch. VLAN1 = 10.105.44.x with gateway .254 (the Cisco). VLAN2 = 10.106.45.x with gateway .254 (the Cisco). The Cisco's VLAN3 is available on only a single port on de Cisco, connected to one of de NIC's of the Asterisk box, eth1, with IP 10.106.46.1 and gateway .254 (the Cisco). The other NIC, eth0, is connected to the switch, on a port setup for VLAN2.
So, what I'm trying to achieve: Use eth1 tagged with VLAN3 to connect to the SIP trunk. (I could do this with a static route because my provider has a fixed IP to connect to) Use eth0 for all other traffic.
Here are some config files I've setup so far (I'm stuck on connecting to the SIP provider):
network
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=localhost.localdomain
GATEWAY=10.106.45.254

Apr 15, 2009So I have a pretty big networking nightmare on my hands right now. Stepped into the dog crap with this one, told my employer that I knew how to setup vmware servers right? Its not hard, install CentOS, install vmware, run the config tool, bridge the network, down the road we all go right? We have 3 servers running about 10 virtual servers.
Here is what we have all together.
CFU <- This is the internet. We have IP ranges xx.18.230 - xx.18.241 Gateway is xx.18.254 and subnet is xx.255.128
DELL PowerConnect 3348 Switch <- This is what everything is pretty much jammed into.
VMH1 <- This machine has 2 NICs
eth0 connects to the DELL switch somewhere on the upper 30+ ports
eth1 connects to the DELL switch on port 1.
It uses firestarter and is the gateway for our internal internet on 192.168.11.XX using IP 11.254. It has 4 vm's on it. One of them is the domain controller, hooked to eth1 using IP xx.11.1. The other one is a server for managing remote backups, it has an external IP linked to eth0 of xx.18.234. The other 2 vm's are for misc remote login stations that use internal ip addresses linked to eth1. It hasn't had a single problem communicating on either one of the ports..
VMH2 <- This server hosts a web server, and some other misc stations.
It hosts a web server on xx.18.230 and xx.18.231
It also hosts 2 workstations on a seperate network, through another router that is wireless....
Now, we have the problem child, VMH3
VMH3 <- This hosts...nothing. It sits and has a ton of storage, but does absolutely nothing, but won't communicate out either one of its network ports.
The xx.36.xx and xx.22.xx networks are there because we have multiple businesses in the building that shouldn't see each other.

CentOS 5 Networking :: Looking For Realtek 8112L Card Setup?
Aug 23, 2010I've done some research for CentOS and Linux support in general for this card, and I haven't found the answer I'm looking for. Does anyone use this card in a system of theirs, and, if so, how easy was it to set up? It's on an Asus M4A785T-M/CSM motherboard that I'm looking to purchase (Newegg link here for reference). I've seen a lot of Realtek cards have zero problems in Linux before, but I know each chipset is different.

CentOS 5 Networking :: Setup Public Accessible VPN On The Internet?
Jul 8, 2011I am running CentOS release 5.6 (Final) and have successfully installed PPTPD and this works great internally.
I want to access my Linux box remotely on the internet via my VPN tunnel. However I am not sure what I need to do on the Linux box to make this happen. My linux box is multihomed as follows
PSTN WWW <===========> ADSL Router Firewall <----------------> [eth1 192.168.x.x] Linux Box [eth0 172.16.x.x] <-----> to LAN
The desired topology is as shown.
VPN Client <------> Home ADSL Router <======= PSTN WWW =======> ADSL Router <------> eth1 Linux Box
1. The VPN is setup and bound to eth1 and eth0 and works well internally
2. IPSec, GRE and PPTP rules have been declared on the router which port map to eth1
However I am still unable to setup a VPN connection to Linux Box I suspect something hasn't been done or I have setup my NATing or IPTables correctly on the linux box.
Networking :: CentOS Mail Setup - Sendmail Via External SMTP Server
Jul 30, 2011I am setting up a CentOS box as a NAT firewall that needs to also send mail. It needs to send this mail using an outside provider's SMTP. The provider requires SMTP over SSL. None of the machines inside the NAT will ever send mail except via the provider's SMTP nor will they ever receive mail except to local clients via the provider's IMAP servers.
So for the example the machine is TESTMACHINE. There is one internet facing ethernet port connected to a DSL modem via pppoe.
The SMTP it needs to send mail via is mail.host.net which requires SMTP over SSL (port 465) and username/password authentication.
The sendmail documentation is quite confusing on how to get this simple setup operating, so an example showing the appropriate changes to sendmail.mc and other require config files.

View 1 Replies View RelatedCentOS 5 :: Boot Setup From Partition That Is Formatted During Setup
May 5, 2009Here is a thought experiment:
1. Copy vmlinuz and initrd.img from isolinux subdir into /boot
2. Adjust grub.conf to boot to that kernel
3. Reboot to setup
4. Format /boot (actually '/' ) during "fresh install"
5. Proceed with the installation-over-network
I see two possible outcomes:
1. The setup fails to reformat the drive, because it is "in use" by boot kernel
2. The partition is not "in use" and the installation succeeds
Why? Old cluster with broken CD-drives, lacking USB, and no separate /boot partition.

CentOS 5 Networking :: Setup The Cluster To Automatically Failover The Service To Another Node Case One Node Fails?
Mar 1, 2011I am familiar with windows 2008 cluster servers, and I just started testing with centos cluster. I am creating a simple 2-node cluster, for a simple ping test.
Node 1: 10.0.0.1
Node 2: 10.0.0.1
Virtual ip: 10.0.0.10
So far, I can ping a virtual ip, and manually relocate it between the nodes, but I didn't figure out, how to do this automatically. So this is my question: How can I setup the cluster, to it automatically failover the a service to another node case one node fails?

Feb 4, 2010Im trying to setup multiple domU through the default bridge setup. I am able to access only one of them through the network at a time. If you ping one of the domU it works perfectly but you cannot ping any of the others until you stop pinging the one and even then it takes a bit before you can. Ive looked around for a while and seen similar problems but nothing ever seems quite the same. Im probably missing something really stupid. Or is this the way the bridge is supposed to behave? Do i need to use a routed virtual network?

Jan 19, 2010We are trying to set up a NIS server on a CentOS system. We need to have a NIS server which can provide NIS authentication to a couple of clients. We are practically new to all this stuff.
Just googled to find some ideas about installing ypserv and ypbind and portmapper. We did all that and also started them successfully. But now the clients are not able to join to the NIS domain . The error log states "YP_DOMAIN NOT BOUND".
I guess we have not entered the /etc/yp.conf, /etc/hosts files properly. Please let us know the detailed steps to setup a NIS server .
Also, please let us know what entries should go into the different /etc/<file_names>? What is meant by HOSTNAME in the /etc/hosts file?
Is there any other files which need to be changed? Are we missing any steps?
Also to add-on, while executing the ypinit command we faced the following error:
At this point, we have to construct a list of the hosts which will run NIS servers. localhost.localdomain is in the list of NIS server hosts. Please cont inue to add the names for the other hosts, one per line. When you are done with the list, type a <control D>. next host to add: localhost.localdomain next host to add:
The current list of NIS servers looks like this:
