Server :: Kick Start Inastallation In Rhel 5
Jan 18, 2010
I have problem while configuring kickstart installation in rhel 5.2 .
I have followed bellow listed steps.
i, Copied iso.img into my server
ii, # mount �o loop iso.img /tmp/iso # cp -a /tmp/iso/* /tmp/iso_new/ # system-config-kickstart - - generate ks.cfg ( creating kickstart configuration file) # cp /root/ks.cf /tmp/iso_new/isolinux/ ( As suggested by red hat I have copied ks.cgf file into /isolinux/ folder.
iii) mkisofs -R -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -o /tmp/new_1.iso /tmp/ iso_new # to create bootable disk
iv) Then started the system using this newly created iso image through HP ILO console and the system got booted successfully with boot prompt.
v) After executing the linux ks=cdrom:/ks.cfg from the boot prompt, we got a error by saying there is no CDROM deducted in your Machine and the installation got terminated .
vi) As per my understanding the ISO image is mounted as Virtual CD-ROM (/dev/scd0) in HP ILO.
Why the we are getting CD-ROM related Error ? How we can avoid this error? Is there any other set of configuration to achieve this ?

I have a RedHat box that I have configured, security, audit rules, latest updates, etc. I want to be able to "image" that configuration so I can kick other boxes with that "image", that way no other configuration/updating needs to be done on the newly kicked boxes. What is the best way to accomplish this? To make things more difficult, it would be near to impossible for me to pull any software off the internet for this.

I am customizing CentOS and doing the entire procedure through ks.cfg file. Everything is been configured properly except the boot label. I would want Boot label to be customized rather than the default one. Is it possible to achieve this using kickstart?

I have ks.cfg and file.iso burned to a DVD. Both files are at the root of the DVD. Besides that, I also created a folder and keep some drivers in the folder.
I inserted the CD and reboot the server ( which already has a red hat 5.3 that I installed before, I want to erase it using kick start ).
Howver, I just can't get into the much said "boot prompt".
Do we need to press certain hot key during certain stage of reboot?

is possible to edited the default RHEL CD to have it automatically install RHEL based off of a kickstart file that I will store locally on the CD. My plan would be to put a cd in a server and have the OS automatically being installed.

I have a database server running RHEL 5.1 32 bit that suffered some catastrophic failures about 6 months ago. We were able to patch it back together and keep it running, but now the manufacturing site it supports is going to shut down for two weeks and I would like to replace it permenantly. Does anyone have any guidance for that sort of thing? I'd like to have the new server up and running before hand, basically changing the hostname/ip and restoring the databases only on conversion day. I've done this in the past with HP UX - Red Hat conversions, but this is my first red hat to red hat move. Any advice or shortcuts?I forgot to add the other wrinkle. The new server will be running 64bit linux.

I have a problem with a server with os Linux RedHat Enterprise AS 4.7:
when the server boots both ntpd and rpc.statd fail to start.
looking into /var/log/messages I found:
and
For ntp, when the server completed the boot process, altough it seems ntpd started, no external server is used for syncronization. The rpc.statd does not start at all and it doesn't appear if I issue a rpcinfo -p
The strange thing is that at this point if I manually start or restart /etc/init.d/ntpd and /etc/init.d/nfslock both services start with no errors. Another strange thing is the timestamp for messages into /var/log/messages. How could it be possible to have a line with a certain timestamp and the following with a timestamp 30 seconds before?
The kernel version in use is 2.6.9-55.0.12.ELsmp #1 SMP x86_64

How can I see which SELinux rule kicks in at a given point. Is there something like debug-mode for SELinux? The problem is that SELinux Troubleshooter does not show any errors at all when denial happens.

I have a client that needs 5 machines updated. They are all running Ubuntu 9.04. Long story short, I can only log in over VPN for the time being (as they're in another city).
That said, is there any good way to remotely update the systems without the need to remain logged in (e.g.via SSH)? I'd like to simply kick off the updates and check back in at a later time.

I am running Kubuntu 11.04 and I use the standard "Blank Screen" screensaver. I want to start a command every time the screensaver starts and to stop it when the screensaver stops.
My idea is to copy the "Blank Screen" screensaver and add a couple of my own lines in the source code ...
but I have some trouble finding the correct files.

I cannot ssh into an RHEL 5.5 server (192.168.20.104) from another RHEL 5.5 server (192.168.20.101) unless server debug is turned on 192.168.20.104, and even then, I have to wait several minutes before the connection is established. scp to and from the 104 server is also not working.Here is the debug output on the 101 server when server debug is not enabled on the 104 server-:

Having some issues setting up sendmail on a (basically) blank RHEL 5.5 server setup. My ultimate goal is to be able to automagically send logs / errors / notifications to ourselves from the server.
Our basic setup is a Win 2003 domain with exchange running on mail.domain.com.au.
I've edited the '/etc/mail/sendmail.mc' and added the :
Code:
line to it.
Also added the domain (domain.com.au) to the '/etc/mail/local-host-names' files
Also edited submit.mc and added
Code:
When I try and send a mail from root or a test user to one of the domain accounts, it seems to go fine, i.e no errors are reported but it never gets delivered.
From the mail logs:
Code:
So it seems to be sent to the queue no problems and when I check the queue :
Code:
Total requests: 0
Not nothing ever gets received. Am I missing something? I have read and read and read but dont seem to be getting any furthur.
So in the end this server doesn't need to do anything except be able to send mail from root to an external mail address.

In oreder to run an application software on RHEL 3 ES server, I created a link forcefully using following command from root id:
# cd /lib64/tls/
# ln -sf libc-2.3.4.so libc.so.6
before that I copied file libc-2.3.4.so from a workstation with OS RHEL 4 WS so that a link can be created.
Now I am unable to run any command except cd & pwd and it gives error messaage as given below:
ls:relocation error:/lib64/tls/libc.so.6:symbol _rtld_global_ro,version GLIBC_PRIVATE not defined in file ld-linux-x86-64.so.2with link time reference.
Before running this command libc.so.6 was pointing to libc-2.3.so file in path /lib64/libc-2.3.2.so.
I am now unable even to open a new window on the server.Please send me some solution as early as possible because this server is running production data and many users are runnig application on this server.

we are running a Red Hat Enterprise Linux ES release 3 (Taroon Upd 5) Kernel 2.4.21-32.ELsmp since several years. The server hosts an old ERP system who will be replaced at the end of the year.However it is necessary that some collegues are able to write some files to that server regulary. Since we are running Windows 7 on several machines, those users aren't anymore able to write to the samba share. Getting files from the share works fine.
But the problem seems not to be situated at the samba service because also the transfer using SSH (WINSCP) from any Win7 system to the server doesn't work.During testing we recogniced that transfering files smaller then 1kb works fine ... any file greater then 1kb ends up in an connection abort. This works with samba and also using SSH.All the workarounds editing some registry entries in Win7 for improving the interoperability between vista / win7 and samba don't work for us ... and also seem not to be the source of the problem.Is there a general known incompatibility between our RHEL version / kernel and Windows 7 regarding file transfers?

I have a RHEL 5 server with 32 bit architechture that is not recognizing more that 4 GB of RAM and I am trying to locate a version of the kernel-PAE package that will work well with the 2.6.18-53 kernel. I found something on Open VZ called ovzkernel-PAE that is built for the 2.6.18-53 kernel [URL]
and wanted to find out if there were any known issues with this release before I attempted to install it. Is anyone aware of any issues with any rpms on openvz.org or with this particular rpm in general?

I am trying to look at installing the PAE module on a RHEL 5 2.6.18-53 system and I cannot seem to find that around. I had hoped to find out if installing the CentOS 5 2.6.18-128 or 2.6.18-164 kernel-PAE modules would have a lot of negative consequences? Perhaps one of you could direct me to a download site that would provide kernel-PAE for a 2.6.18-53 build?

I have setup a CentOS 5.5 server as a DHCP server. That will be it's only task in a Cisco callmanger VoIP environment The DHCP server that comes with CentOS 5.5 is from ISC V3.0.5 -redhat.
The server (HP DL360) has two physical NIC's of which only NIC1 is used (ETH0)
ifconfig shows:
Code:
The interface has a fixed IP setup.
My dhcp.conf file looks like this:
Code:
When I start (try to) dhcpd via the service interface or via the prompt as
Code: service dhcpd start
I get an [FAILED] message and the following is in /var/log/messages
Code:
But when I start the DHCPD on the comamnd prompt in debug mode it looks as follows:
Code:
and /var/log/messages shows:
Code:
Why does the system ask a declaration for eth0 0.0.0.0?

I'm configuring a new Centos 5.5 server in replacement of an old W2K server.The topology of our network is simple : one file/dhcp/dns relay server and workstations (PC's and some MAC's) plus network printers and scanners.All the workstations have dynamic IP addresses (easier because a lot of 'dynamic' changes : new persons with their own laptop, ...) and the server and printers/scanners have fixed IP addresses.I edited the dhcpd.conf (see here underneath), I have the file dhcpd.leases but it doesn't start !

I have seen and tried a lot of web information about issues with VNC and the RHEL 5.x implementation of VNC.
I can't seem to get the behavior I want. Let me explain.
With SLES 10, I can use YaST and with a few clicks end up with a system that when rebooted, accepts VNC viewer connections to :1 and displays the system login screen.
Here I can log in as root or any user. Once logged in, I can choose to use the command line to restart the system if necessary and eventually, I can reconnect with the vncviewer to the system login screen.
RHEL 5.2 has a "share your desktop" setting in preferences which works fine, but requires that I be logged in locally, which prevents remote restarts. There is also a system services dialog that refuses to start vncserver as a service. There are numerous tutorial in the RH knowledge base and the web that explain how to specifically setup individual displays, :1, :2 for specific users and claim that it can work after boot. I have not been able to get these working, but what I really want is a simpler, single display, :1, that will present the RHEL login screen so I can log in as any user I want. I am the only person accessing these servers and they are behind a firewall using secure protocols when remote.
I think Red Hat did not want to make this too easy as VNC users need to consider the security risks. Is there a way to get the SLES 10 VNC approach to work on RHEL 5?
