CentOS 5 :: Install Over Tftp/http Fails Due To Invalid Path?
May 2, 2011
I have a problem installing CentOS 5.5 over lan. I set up a dhcp3 server and it works, client got an ip. I set up a tftpd-hpa server and it works, client can boot the install image of CentOS 5.5 I set up an apache server and it seems to be impossible... In the installation marathon I clicked through the menu to the choice of the web server where my installation files are available. I enter the ip 192.168.138.1 and the path CentOS-5.5 and CentOS tells me "Unable to retrieve http://192.168.138.1//CentOS-5.5/images/stage2.img" . Thats right because the two slashes are not right. Where the hell come the two slashes from???
I edited my httpd.conf like this:
<Directory /tftpboot/CentOS-5.5>
Options Indexes
AllowOverride None
</Directory>

When I try to pxe boot a Sun X4100 (which actually has a RHEL OS on it right now) I get the message TFTP open timeout. All traffic is allowed for port 69 udp in both directions. I do get a dhcp address. I see that both on the server and the client it gets an IP. After that I get this message in the logs:

I'm trying to install a dual booting machine with OpenSUSE v11.1 32bit and CentOS v5.2 64bit. I installed OpenSUSE first and allowed it to install and configure grub in the MBR and after that I wanted to proceed with CentOS v5.2. The installation went fine with two notable exceptions:- when I had to configure grub installation parameters, CentOS offered me only 2 solutions: either install it on the MBR of the first hard disk or not installing it at all. Other distributions are more flexible allowing you to install it in the boot sector of the root partition for example. Because I didn't want to ruin the existent grub onfiguration, I reluctantly accepted not to install it for CentOS assuming that I could manually configure the entry later in grub's menu.lst file.
- when I was presented with the options for software components installation, I've clicked on virtualization category/function because I intend to use the machine as a VMware host. There was no guidance on screen at that point and I blindly assumed that by choosing the virtualization function I would get necessary tools and drivers that will help me further on. It seems that this was a wrong move as you can see it below.
After completing the installation, I tried to search for a template or guiding on how the menu entry in menu.lst should look like but the grub directory was empty, not surprisingly because I've told CentOS earlier not to install it. Using the files in the /boot directory from the CentOS installation I tried to improvise a menu entry but it's not working. The boot stops with famous Error 13: Invalid or unsupported executable format. Using the file command to check what kind of files I'm trying to load as kernels I'm getting :
marte:~ # file /mnt/vmlinuz-2.6.18-92.el5xen
/mnt/vmlinuz-2.6.18-92.el5xen: gzip compressed data, from Unix, last modified: Tue Jun 10 19:20:51 2008, max compression

In Jaunty (9.04) I've setup a small (eleven-terminal) ltsp network at the local school. It handled around 6600 working hours with ease.
Now I've upgrade the server to Karmic Koala (9.10) and it just stopped working.
1) The clients have PXE NICs
2) They get the proper IPs from the DHCP server and respond appropriately to changes in the DHCP configuration files.
3) DHCP server also points the clients to
filename=/ltsp/i386/pxelinux.0
4) When the clients try to download the pxelinux.0 over tftp they just timeout
5) /etc/inetd.conf has an entry like
tftp dgram udp wait root /usr/sbin/in.tftpd /usr/sbin/in.tftpd -s /var/lib/tftpboot
6) The file /var/lib/tftpboot/ltsp/i386/pxelinux.0 exists on the server
I'm lost at all these configuration files and protocols.

I was wondering how i can install thru FTP and/or HTTP if the source-path isn't correct recognized by the installer. e.g. http install
Server name:
The installer recognized
[url]
And i can't start the directory without a slash. So, the installer never will find the files it is looking for. Using CentOS 5.3.

I'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:
[root@CentOS-test CentOS]# ls -la

Forgot to add this line from my pxelinux.cfg/default file:
label 1
kernel 5.4/vmlinuz
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?

When I attempt to install a new hardware system over the wire via NFS I get the following error:"unable ro retrieve http://192.168.0.1//install/images/stage2.img."The httpd.conf file is configured to use /var/www/html as the root. I have placed the installation files in /var/www/html/install. In the http install screen I enter the following information:Web site name: 192.168.0.101CentOS directory: installI have tried many different variations in these two entires, but the error always is the samw: the installation script searches for an address which has an extra / character interposed between the server IP address and the directory path entered in the next line.

I have a ELRO C903ip.2 camera. I want to use it on zoneminder but am having trouble connecting. I have set a basic account of visitor with username and password both set as visitor.
The question is what is the syntax to the cameras ipaddress via http passing the u/n and p/w at the same time as part of the http string? I have tried the web page: [URL] .... to no avail, i must be missing something pretty obvious but just can't see it for looking.

I'm trying to install Fedora 13 VM on my CentOS 5.5 64 bit install following the below link. I used this same process to install a CentOS 5.5 VM just to test the process. Now when I try to follow it making changes for Fedora Im getting an error.[URL] config file:
kernel = "/install/vm/fedora/vmlinuz"
ramdisk = "/install/vm/fedora/initrd.img"
name = "fedora13"
[code]...
In the CentOS link I posted it said to use kernel from the xen directory.Ive found out that the last fedora version that shipped with xen was fedora 8. Does anyone know where I can find a fedora 12/13 xen kernel? Ive searched google for hours and can not find a xen kernel. Actually I'm to the point where I would even use ubuntu or any similar distro if I could find a xen kernel.

Using Fedora 14 as a TFTP server. I am neither able to get nor put files on the this server. The error I get is "Timeout occurred." Here is /etc/xinetd.d/tftp:
service tftp
{
disable = no
socket_type = dgram
[Code]....
I have verified the files are in the directory. I have given read/write/execute access for everyone on /home/cisco/ms-sol. On Fedora I have disabled iptables and selinux. On the client (windows xp machine) I also disabled the firewall.
When doing put, for example, I took wireshark capture from the windows PC and I see several "read requests" before connection times out.

I am trying to run though the qmailrocks setup on a centos 5.5 and I am running into an issue when trying to telnet to port 25:
telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
Connection closed by foreign host.
Everything else seems to be working (telnet to 110), and I turned off the firewall entirely, but I still cannot telnet to port 25. I also get a blank error within squirrelmail when attempting to send mail out (ERROR:Message not sent. Server replied: ). I apologize for not going directly to the qmailrocks forum, but they are currently closed down (due to lack of funds). I also am a newbie, so I apologize for the lack of needed information.

I'm trying to setup a network boot server and I'm having an issue with tftp. In the /etc/xinetd.d/tftp file, I added the "-v" (verbose) option to the server arg line so that i could figure out what was happening. When i looked at the /var/log/messages log file, it let me know that permission was denied to /tftpboot/nbi_img.
So, in short, my problem is that tftp isn't working because it doesn't have permission to /tftpboot/nbi_img. I can't figure out why. I stumbled upon a site where the user figured out a temporary fix to this issue and what he did was disabled the xinetd service and typed the following command:/usr/sbin/in.tftpd -l -v -v -s /tftpboot/nbi_imgWhen I do this as well, it works! but only until I restart and then I have to do that again. Is there a way to be able to fix that for good?

So I'm playing around w/ some Cisco equipment and needed a quick tftp server. Go to command line and type yum install tftp-server. I get No Package available! I can clearly see it here on the i386 repo. Any ideas?? In the meantime, I'm just going to upgrade this lil 600m laptop to CentOS 6 to quickly solve the problem but I thought it was curious.

I am trying to wade through the semanage jungle to get permissions for a tftp client. I followed the HowTos [URL] but I get the following at the client:
tftp> status
Connected to 192.168.1.101.
Mode: netascii Verbose: off Tracing: off
Rexmt-interval: 5 seconds, Max-timeout: 25 seconds
tftp> get hello.o4
tftp: hello.o4: Permission denied
I finally figured out that the firewall directives shown at the end of the HowTo refer to semanage although the options are stated incorrectly according to the man page for semanage. I did insure that the file hello.o4 in /tftpboot has read permission for everybody.

Please consult the The X.Org Foundation support. Please also check the log file at "/var/log/Xorg.0.log" for additional information. So then after some googling I got the suggestion to downgrade udev-151 to udev-141, but that yeilded no results. So I did some more googling and a bunch of people who had the same problem said that downgrading module-init-tools worked, so I downgraded from module-init-tools 3.11 something to 3.6 and now, not only does my X no longer work, but no modules are being loaded I believe, for example I saw in my startup that fuse was not being loaded, ndiswrapper which I had installed was not loaded.

I have an old PC with two hard drives (40 and 60Gb) and it uses dual IGhz pIII processors. It shares screen,mouse and keyboard with another PC.Both into Netgear modem. It ran ubuntu 8.04 and XP Pro on the drives above with no problems. Then I decided to try Mint 11 (34bit CD) - result after Grub blank screen other than flashing cursor at top left.No input from keyboard.
Tried Mint KDE 10 (34bit DVD) same result.
Tried Kubuntu 10 (CD) same result.
Reinstalled Ubuntu 8.04 no problem.
Upgraded via download from 8.04 to 10LTS hoping that this would somehow prevent the problem and have screen which says:-
starting up

mount: mounting none on /dev failed: No such device
udevd[825]: error getting socket: Invalid argument

udevd[825] error initialising netlink socket
libudev: udev_monitor_new_from_netlink:error getting socket:Invalid argument

Gave up waiting for root device.Common problems:
Boot args (cat/proc/cmmdline)
Check root delay (Did the system wait long enough)
Check root (did the sytem wait for the right device)
Missing modules (cat/proc/modules; 1s /dev)
ALERT! dev/disc/by-uuid/"long number here" does not exist.Dropping to a shell.
Then it goes into Busybox and ends with "initramfs". I have tried altering the boot device in BIOS from HDD0 through 3 with the same result other than more bad language!

Not new to CentOS, which I've installed on a few servers. I'm trying to turn a very old laptop (11 years ?), Toshiba Tecra 540cdt (with the latest available BIOS), into a home server. It runs Windows 2000 fine, and was earlier running some Mandriva versions. I'm trying a multi-boot install, from CD1of6. It does boot from the CD, then shows:
boot:
Loading vmlinuz...
Loading initrd.img...
then reboots, and goes through the same cycle.
I switched the hard disk, same result. I have problems too if I try to install the latest Knoppix. An older Knoppix, 5.1 with kernel 2.6.19, will boot.
