Server :: HTTP Network Install - CentOS 5.4
Jul 9, 2010I've been attempting to setup PXE/HTTP network installs so we can better handle deployments for new systems. I have a test CentOS 5.4 VM running, and another test VM that I want to deploy 5.4 to. TFTP, DHCP are all working correctly. Apache 2.2.3 config "seems" OK. When I kick off the VM which I will install to, DHCP discovery and IP allocation works, the TFTP server is found, I am presented with a menu option of OS selection.
I choose #1, for my 5.4 but then it immediately tells me:
"Invalid or corrupt kernel image"
/var/log/messages doesnt show anything other than the DHCP OFFER/ACK process and that TFTP client doesn't accept options
/var/log/httpd/error_log doesnt show anything either
Not sure where else to look for diagnosis.
My Apache config directory: /var/www/html/CentOS
Content listing:

append initrd=5.4/initrd.img ramdisk_size=16000 method=http:/10.37.129.3/CentOS ip=dhcp
(I think I have found my problem.. 5.4 was in the TFTPBOOT directory, but now that I'm using HTTP, I changed this to be:
kernel CentOS/vmlinuz and append initrd=CentOS/initrd.img) -- question is, will just changing this work?

View 1 Replies View RelatedCentOS 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

Jan 12, 2011My company hosts five Servers with CentOS 5 installed in a Data Center. The Data Center assigns a VLAN to each customer so that they can organize customers and also count traffic. The VLAN assigned to my company is in the form 62.103.X.X with a subnet mask 255.255.255.240 so the IPs that we can use in our Servers are 13. The first IP in the VLAN (for example 62.103.1.1) is the Gateway and the rest, that are calculated from the subnet mask, are assigned to servers(62.103.1.2 up to 62.103.1.14).
The problem I have is that we have run out of IPs in our VLAN. We have used all IPs and we want some more. The Data Center can assign new IPs but not grow our VLAN IPs by expanding the subnet mask. So they gave us a new VLAN with some IPs (for example 62.104.X.X with a subnet mask 255.255.255.192) They told me that I had to use as gateway the gateway of the first VLAN 62.103.1.1 and assign the new IPs as usual. So I assigned to one of the CentOS 5 servers the IP 62.104.1.2 and set the gateway to 62.103.1.1. Unfortunately this did not work and we could not establish connectivity to the Internet.Is it possible to assign a gateway outside of the IPs that are in the subnet? Could it be a problem with the VLAN setup by the Data Center?
Ubuntu Installation :: Network Install From ISO - Cannot Transfer Files With Apache HTTP
Feb 24, 2010I have tftpd-hpa and dhcp3-server up and running. I just want to install server edition via network, from the host machine (my laptop, running ubuntu 9.10) with an ISO file (ubuntu 8.04 32-bit server edition). I managed to boot the client machine with pxe-netboot technique, but instead downloading all the files from internet, I need to do this process directly from ISO. To transfer ISO from host to client, I also installed Apache. I unpacked ISO file into /var/lib/tftpboot/server/. I created a link to the Apache root: /var/www
Code:
ubuntu@ubuntu:/var/www$ ls
returns => index.html server
server folder is the place where I unpacked the ISO.
My dhcp3-server has this setup and it works well with netboot, but I don't know how to add Apache to the formula to transfer the iso file from host to client. Firewall is disabled. This is my edited /etc/dhcp3/dhcpd.conf file.
Code:
host pxeinstall {
hardware ethernet 00:06:29:DE:E3:CD;
fixed-address 192.168.2.4; (client IP)
next-server 192.168.2.2; (host IP)
filename "/server/install/netboot/pxelinux.0"; (relative to tftpboot)
} subnet 192.168.2.0 netmask 255.255.255.0 {
range 192.168.2.2 192.168.2.5;
option routers 192.168.2.1; }
When I pxe-boot the client, the process comes to a halt when tftp server is trying to access to pxelinux.0 file. I got thls error:
PXE-T00: Permission denied
PXE-E36: Error received from TFTP server
I have no experience with Apache... so I think there is a problem with my IP addresses.. Do I need to use 127.0.1.1 instead of 192.168.2.1 (my routers IP)?
Networking :: Layer 2 Switch - VLAN Router To Network
May 15, 2009Our ISP provides us with Layer 2 hardware (Modem?/Switch? (Hatteras)) for our leased line and internet access. I have been told that I should set up a VLAN capable router to separate the internet traffic from the internal traffic. I found that linux is capable of VLAN routing. Nice!
I have setup opensuse 10.3 put in two NICs and did the following
vconfig add eth0 10
vconfig add eth0 20
ifconfig public.ip.add.ress netmask 255.255.255.252 eth0.10 up
ifconfig 192.168.0.1 netmask 255.255.255.0 eth0.20 up
Plugged this NIC into the HATTERAS hardware (with a straight cable), and thought that this way I should be able to ping the public gateway or any ip out on the internet. My ISP is telling me that I should create a VLAN trunk to be able to 'use the internet', but as I understand in linux if I create any number of VLANs on one NIC they are already trunked. I also got the info, that the traffic is tagged, and I can separate the traffic reading the tags. I already read that some NICs are not able to VLAN because they are not able to handle the increased packet size.
Also that the MTU setting is important (dono' the exact value though, only that its important). I thought that a linux machine can act as a router and firewall in such a case, because proprietary switches/routers use linux as embedded os. This is my first meeting with VLAN so if this whole post does not make any sense or you think that I just need to RTFM more then tell me! I also have some (3) Dlink 3226 Layer2 switches around, but I think it would be waste to use a 24 port switch on this subject.

Fedora Networking :: Setting Up A Vlan Network And After Reading Several Man Pages?
Sep 8, 2010I'm currently setting up a vlan network and after reading several man pages I still have 2 questions / problems:
1. I would want to put several subnets into one vlan.Meaning for example, I want to have the following Vlans with subnets:
vlan1 10.1.1.0/24
vlan2 10.1.2.0/24
vlan3 10.1.3.0/24
vlan3 10.1.4.0/24
vlan3 10.1.5.0/24
Is that possible?
EDIT: I found a sample configuration, sadly without any comments, where there are defined some interfaces named vlan1:0 trough vlan1:3. Could that be the option I've been looking for.However in the definition of the vlan1 device it is configured with the subnetmask 255.0.0.0 . I would like to know the mechanics of that option, too.
2. In the wlan part of the network I want to have a dhcp server distributing ip addresses. However I want hosts the server 'knows' (by mac address) to be in a different vlan than those unknown. Is there any way to achieve that? If yes, do I need special wlan access points or can I do it by my configurable switch or by the server?

View 1 Replies View RelatedCentOS 5 Networking :: Transactions Timeout - Yum / Wget And HTTP
Apr 28, 2011I am having a problem with 5.4 that I did not have with 4.5. The problem happens only sometimes but in specific instances. Basically a summary of the problem is that certain network transactions timeout. The specific instances are with wget, rpm, http. The problem usually, but not always, occurs with pptp stuff. (NOT running pptp but getting pptp stuff). For instance, the following command, which finishes in seconds on non-5.4 OS's:
wget [URL]
downloads about 20% then gets stuck. About 5 minutes later it downloads another 20% and then gets stuck, etc. The same thing with rpm:
rpm -ivh [URL]
waits about 3 minutes and then gives an error. I think it does the same thing as the wget but
wget will keep trying, while rpm gives up. The error from rpm:
Retrieving [URL]
..five minutes later:
I can wget the above as I mentioned before and install it that way. Before I do it, yum works fine. Afterwards, yum exhibits the same behavior of timing out (because it is using the pptp repository). Also visiting the pptp web site from Firefox times out on certain pages. I originally thought it was some problem with the pptp site, but I notice that log into hotmail.com. Does the same thin (fine on other operating systems). A view with Wireshark on the wget (pptp) shows the my machine receiving a reassembled TCPPDU from 216.34.181.96 (Sourceforge), sending an ack, receiving a reassembled PDU, sending an ack, receiving, sending followed by the 5 minutes or whatever of nothing. Then sourceforge sends an RST and a SYN and the process is repeated.
When I put the machine directly on an AT&T IP connection (12.147.X.Y) everything worked fine. Same with Comcast on a direct link. The times I am having problems is when our router is hooked up to a Comcast IP (70.88.X.Y) and assigns 192.168.5.X addresses to our machines. So when I was doing the above from 192.168.5.27 going through the router through Comcast is when I had the problem. So it is probably something with the router, but it is hard to figure out since CentOS 4.5 and Fedora do not exhibit this behavior, nor does 5.4 on most sites (mail.yahoo.com for instance). I did verify, at least from what I could, that ICMP type 3 and 4 are not being blocked. If they were, the same problem would happen on other op systems. And I was able to ping, albeit just locally, but we looked at the router settings and ping was not blocked.
