View 1 Replies View RelatedI am in a VMware environment, and using RHEL 5.4. I am trying to setup a PXE Kickstart installation. For this I have configured DHCP and TFTP, made a kickstart file and shared it in the network through HTTP. My problem is that somehow kickstart file (ks.cfg) is not picked by the machine in which I am installing the OS. Although, the contents of my kickstart file can be viewed over HTTP. Please see KS_Error.jpg.
[Code]....
However, I believe DHCP and TFTP is working fine as I am getting the correct IP 192.168.1.115 which I have set in /etc/dhcpd.conf. Also, my label 1 which I have set in /tftpboot/linux-install/pxelinux.cfg/default is working fine as I able to locate initrd and vmlinuz. Please see attached Image_1.jpg how to troubleshoot this. I need to paste any of my configuration files?.
I don't understand the results of a simple performance test I ran using two basic scripts (running on a high end server):
perfVar.zsh :
#!/bin/zsh -f
MYVAR=`cat $1`
for i in {1..10}
[code]...
Performance test result:
> time ./perfVar.zsh BigTextFile > /dev/null
./perfVar.zsh FE > /dev/null 6.86s user 0.32s system 100% cpu 7.177 total
> time ./perfCat.zsh BigTextFile > /dev/null
./perfCat.zsh FE > /dev/null 0.01s user 0.10s system 91% cpu 0.118 total
I would have thought that accessing a VARIABLE was way faster than reading a FILE on the file system... Why this result ?Is there a way to optimize the perfCat.zsh script by reducing the number of accesses to the file system ?
I'm trying to create an iso to use for a kickstart installation.
I mounted the Rhel6 boot DVD, copied the files(recursively cp -r /mnt/dvd/ ~/myiso) to a directory ~/myiso
I then placed the ks.cfg on ~/myiso and ~/myiso/isolinux for good measure, as the documentation is not 100% clear on this.
I then try to make an iso out of ~/myiso but no luck in booting so far.
I've tried the following:
Code:
mkisofs -o ks.iso -b images/install.img -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table isolinux .

I need to create a Redhat or CentOS server but I am not really sure where to begin. I'm not sure what network booting and PXE booting is. Are they both the same thing, or are they different? I want to setup one server and two client machines to connect to my server. I would like to be able to load a kickstart CD on my server and have the two client machines boot off that servers kickstart. My concern is, will they boot off the network or do they have to be configured to use PXE booting?
View 12 Replies View RelatedI am trying to read the /proc/net/tcp6 file of a huge server (chat server) for monitoring the tcp6 connection states.
This tcp6 file has more than 26000 lines. For monitoring the server connections, my monitoring tool has to read the /proc/net/tcp6 file quickly in regular interval. Presently it takes minimum 6-7 seconds for reading the whole file.
My tool can able to read the normal file (26,000 lines) less than 1 second, but it is not possible to read the same size of proc file.
I have 2 questions:
1) Why proc file takes more read time than normal file?
2) Is there any way to read the /proc/net/tcp6 file more quickly?

I am a bit confused about a dual booting system. I Already have windows 7 on my computer and wish to install ubuntu 11.04 but I keep reading about Grub 2. Does grub automatically install with ubuntu or do I need to install it prior to installing ubutu ?

I am currently trying to add a new user on a linux box in the %post section of the kickstart file. The user however doesn't get created after I reboot the box after install.

View 4 Replies View RelatedI can't figure out how to copy a file off a custom RHEL 5 DVD that I created with kickstart after the installation completes and the %post runs. I don't want to run as "%post --no-chroot" because I have a script of system changes that needs to run in chroot. I just want to copy one RPM file into the /tmp so my script can install it. Can I have two %posts, one with chroot and one without? I can't seem to find any RHEL 5.5+ guides for kickstart that can explain to me how to make it work.

We have done it before in the past just fine using:linux nofb text ks=http://serverip/path at the boot/install screen. After that the ip address info is entered manually and the kickstart does its thing. When doing this with update 7, the install acts like a regular install.

View 2 Replies View RelatedI'm unable to create a linux boot cd with a kickstart file. I have a working kickstart file and a working boot image (tested by booting using the network for the kickstart file), but I can't seem to put them both on the DVD.
Here are the steps I took
1. mount the *.iso file to /mnt/isosetups
2. Recursively copy all the files from /mnt/isosetups to /mnt/bootcd
3. removing /mnt/bootcd/isolinux/boot.cat
4. running the mkisofx command (used -c to recreate boot.cat)
5. put the new image on a windows box and burned to a dvd using roxio
The result was that I could enter the red hat boot menu but the server couldn't find the boot image on the cd. I could go into more detail about what commands I entered, my environment, what I tested, etc.
I'm using RHEL 5.4 and trying to use the system-config-kickstart to generate a ks.cfg file with all the settings already appeneded. After running the "system-config-kickstart --generate ks.cfg" command, the file gets created but it's missing the firewall configuration, partition information and so on.
How can these settings also be generated with the system-config-kickstart?

View 3 Replies View RelatedI have recently been given the task of setting up some thirty odd netbooks with F10 and i was wondering if there is a way to generate a kickstart file from the first netbook (my one lol ) that i have setup to our needs so as to use it to create the same install on the rest of the netbooks. i had thought that i could use the anaconda-ks.cfg file in root's home dir but it is not at all representative of the custom package list i chose during the install.

I am using a backup system with cron + tar. Since the server is very busy, I get often the cron-email: "The file XYZ has changed while reading". This message is a bit annoying and I see it as critical point in my backup system. I believe that this file is then not in my backup. (Is that correct?) Let's imagine the hard disk dies and I have to recover the system and my personal data, and in the night the mysql-table XYZ was not in the backup, because it was in read-usage. I would then have lost this table forever. Is there any way to tell TAR, that it should force the file to be included (if in read-usage, then wait 2 seconds and try again)?

the xmlhttp.responseXML is null and the script crashes. Could this be a permission issue? I tried setting the data.xml file to read-write permission for any user but that didn't work.

This, at least is more than I was able to do previously (prior to 10.04 and several earlier versions of Gnucash running in 8.04 through 9.10). Before it would cause Gnucash to crash and shutdown. I select a specific account with categories from Quicken to export.
