mkbootdisk! [SOLVED]
by israel.garcia＠cimex.com.cu 06 Apr '05

06 Apr '05

First, I thanks you all for your answers. Step by step what I did. 1. Install from CD1 CentOS mkisofs-2.01.1-5.i386.rpm 2. create the file /tmp/2.6.9-5.0.3.EL.iso 3. run mkbootdisk --device /tmp/2.6.9-5.0.3.EL.iso --iso 2.6.9-5.0.3.EL 4. Burn this ISO image to a CD. That's it!! regards, israel

Well I now have a 4.0 server at a solid checkpoint. Before I start the chore of setting up SAMBA and LDAP. Part of the delay was I did not copy all of the needed DNS files, and I have to reerad the BIND book. So I want to be able to get to this point again easily. I did not note down what options I had selected during install. Is there some way in the install log to figure that out? Is there some way to do an image backup? I only have a Win2000 server available for the backup, no NFS on another system. Appreciate any and all help. Barrs Law of Recursive futility If you're smart enough to use one of these.... .....you can probably manage without one!

Collins, Most of my servers are connected remotely, I migrated from WhiteBox to CentOS linux, I had in every (remote) server a bootdisk (floppy), so in case of a raid crash, some people there booted the server from the bootdisk and then I reconstructed the Raid remotely... I know if I boot from CD rescue mode I can get the same result, but, people in thouse places are not especialized in linux boxes. That is because I want to boot from a floopy, now I also know it's imposible, but, Can I make a CD boot?, I just want something to boot my remote server, get running all services and later I reconstruct the RAID... understand me now? sorry my poor english! regards, israel

Re: [CentOS] CentOS for commercial use

At what point did Red Hat's efforts in the open source community become magical and change the ethical environment Red Hat lives in for people downstream of Red Hat? Your question pre-supposes that because CentOS is downstream of Red Hat then somehow it is different than Red Hat being downstream of the Linux kernel developers & others (fill in other names as you see fit). Red Hat is downstream of well over 99.99% of the 'major work'. Red Hat has built a business around using freely available software. As part of the licence provided by upstream authors who created, enhanced, and often support the software Red Hat is required to make the software source others created and they use for their business available to others to use as they see fit (within terms of licence). Exactly the same as Red Hat taking the source from upstream and using as they see fit (WTOL). Commercial vs. community support is not an ethical choice. Neither is Red Hat's leveraging the efforts of the community to build a commercial enterprise. The community knowingly provided their efforts to others to do exactly what we, and Red Hat are doing. regards Dave HornfordAssociates.com

RE: [CentOS] Netatalk ???
by Tracey, Michael 05 Apr '05

05 Apr '05

Mario, That is correct (at least on 4.0), and the appletalk kernel modules are not built, so you will have to build a custom kernel to use it. Once it the kernel is recompiled and appletalk is compiled, it works like a champ. Netatalk is not hard to compile.

I know the option "linux rescue mode" works fine, but, my CentOS servers have a Software RAID (raid 1) installed and I used to make a bootdisk in case of a RAID failure (or a HDD crash), so, Now I can not make my bootdisk 'cause the error above...... in this case what can I use to boot my server and keep my Soft RAID working? thanks for all your soon answers regards, israel
