Re: [CentOS-docs] Samba
Hi guys, Sorry for being MIA. Catching up on post-holiday (in the US) work. I'll start working on the basic howto and throw it up here for review. While I agree something like this may be too simple for many of us, I firmly believe that a large majority of the people browsing the howto section are going to be looking for something real basic. The people who want to deploy much larger and complex installations really need to be looking at the main documentation of the product, and not some canned solution. I'll go over the whole thread and reply where necessary. If someone else would like to write this basic samba howto up, by all means go ahead (but let me know so we both aren't working on it) :) I'm just throwing it up to the docs community. Thanks! -will ___ CentOS-docs mailing list CentOS-docs@centos.org http://lists.centos.org/mailman/listinfo/centos-docs

The problem seems to be that anaconda has a problem with having a network card statically configured :-( All I had to do is change the bootproto for eth0 from 'static' to 'DHCP'. Now it successfully retrieves 'stage2.img' file from the web server and completes the installation with zero intervention. For the time being this will do, but I'd rather the clients have everything configured locally once when installing than accessing the network for any information they need (this configuration is for a HPC cluster and every network access decreases performance). -- TIA Paolo ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

The default /etc/sysconfig/nfs on CentOS5 however has defaults under 1024, such as mountd 892 statd 662 rquotad 875 Is there something security-related going on here that I'm not aware of, or some other explanation?

For shame! WfW was 3.11, 3.1.1, IIRC actually, there was a 3.10 and 3.11 release of Windows for Workgroups. The 3.11 release introduced the use of 32 bit protected mode implementation of the network stack and file system via extensive use of VxD drivers, and set the stage for Windows95 where almost the whole OS kernel ran in VxD space (prior versions used 16bit realmode IO components from MSDOS). ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

And that was a half-height 5.25 20MB drive. (Today, I couldn't fit two RAW photos from my current DSLR onto that drive. And that camera can shoot 5 frames a second and has a 19-shot internal buffer. And cost less than half what that first PC cost.) I'm sure it was in the 80s still when I was using 30MB RLL drives. Around 1992 I got a 40MB 5.25 full height drive in a new 386-based PC, and also my first laser printer. By 1995 I had 3.5 720MB drives in my PCs. In the earlier 90s I had purchased two 300MB drives, 5.25 half height (for $1500 each, sigh).
