CentOS 5 :: Difference Between /dev/sdx And /dev/hdx
Mar 17, 2009
While playing a bit (fdisk) with a new machine (Intel 2 Duo E6750) that I have (with 2 SATA disks), I found a "strange" thing. If I boot the server from a Knoppix distro, fdisk sees 2 scsi HDD devices (sda and sdb). Ok, this was the expected. But if I boot the machine with the centOS 5.2 x86_64, while doing the partitioning the disks are recognized as hda and hdb, that is, IDE disks.

What is the difference between kernels which come from the update repository and the plus repository ? Often the same version comes from both, but one says centosplus at the end the other, from the update repository, does not.

What is the difference between the boot.iso and netinstall.iso images? I've looked at the wiki and done some Googling, but haven't found a good answer yet. I know it is probably going to be something obvious, but in the context of installing a Xen fully virtualised guest there doesn't seem to be much difference. After booting both ask for the location of the install tree and proceed happily.

i just finished installing CentOS 5 in my laptop. While I was trying to configure my Wireless network to connect internet, I found a guide in CentOS site which recommended to start "NetworkManger" service so as to setup wireless network. I followed and it Worked great.
But i would like to understand the difference between "Network" service and "NetworkManager" service. I had initially thought restarting "Network" service would help. explaining the basic difference between these 2 services.

I have a system with a missing or damaged kernel and I need to reinstall some software to fix it (see this thread for reference removed xen and kernel is gone). I feel fairly certain I can fix my system with the info in that thread however I don't know if this was a 32bit or 64bit system. How can I tell after using the dvd and linux rescue or does it even matter?

df -k
/dev/sda6 25396228 21249088 2836240 89% /export
21G used[code].....
The 3.4G is correct because we have removed all non essential file but free space reported by df is not consistent with the actual free space that should be there.

I've typed 'l' instead of 'ls' in the terminal by mistake a couple of times, and it seems to do pretty much - but not exactly - the same as 'ls' ('l' appends *, @ etc at the end of filenames which seem to indicate permissions and/or links).
I can't find any documentation on 'l'. 'l --help' gives exactly the same output as 'ls --help'. 'which l' gives nothing. There are no files in my filesystem called only 'l' either - just a couple of unrelated folders.
So what's the difference between l and ls?

I have two interfaces, Gnome and KDE. So sometimes I am asked to chose between the 2 display manager gdm (Gnome) or kdm (KDE). I've never noticed any difference. When I have problems with one I have problems with the other, and usually they both seem to function equally well. If you have ever been in a situation where one was better than the other could you please tell me about it? My question is related to troubleshooting a dual-monitor setting but this is another thread, here I'm just asking because I wish to learn a bit more about displays in general.

Problem is the office in way out in the country. I have no interest in driving out there every day for such and such but just thinking of the best solution to a soho that is easy to backup and maybe easy to have the local users fix.
