Grub upgrade for CentOS 5.5?
by Ron Blizzard 04 Jan '11

04 Jan '11

Stupid question (I'm guessing). I'm currently tri-booting (or would like to be) VectorLinux 6 Deluxe, CentOS 5.5 and an evaluation copy of Red Hat 6. I'm using CentOS's grub. VectorLinux and CentOS boot fine, but Red Hat won't load. I think I read somewhere that CentOS's grub is too old for ext3, 256 (something or others). So, is it possible to download and install a newer version of grub for CentOS 5.5? (This has been a problem with other tri-boot attempts). If not, is their a way to boot Red Hat from the install DVD? Since it's only a 30 day evaluation, booting from DVD or CD would be fine, but I don't see the option. Thanks for any pointers. -- RonB -- Using CentOS 5.5

Re: [CentOS] Centos 5.5 - Kernel Panic while booting.

This was very helpful Akemi...I was loading centos in two other identical servers today and was having such a hard time loading it from DVD, DVD appears to be crashing, I even re-downloaded the image 3 times from three different mirrors and burn them with different applications (Nero, Roxio, and poweriso), worse case scenario it must be something with the Memorex DVD Media. Anyway, after two hours of trying I decided to do a network install and everything went flawless. Good to have many options, Centos rocks! >>> Akemi Yagi 12/17/10 8:13 PM >>> On Fri, Dec 17, 2010 at 5:11 PM, Lisandro Grullon wrote: > Akemi, > I went through the different mirrors and was unable to locate the ISO as it > is stated as deprecated or unsupported, is there any plans to fix this issue > in 5.6 or rather 6.x release.

Hi List, Happy New Years and I was hoping to get some help on an ssh issue that I am having. For some reason I am unable to scp to hosts on this network using RSA keys. Here is what I am doing/what is going on; scp the public key to remote host [amandabackup@VIRTCENT18 ~]$ scp ~/.ssh/id_rsa_amdump.pub amandabackup@lb1:~ amandabackup@lb1's password: id_rsa_amdump.pub 100% 408 0.4KB/s 00:00 ssh (w/passwd) to remote host [amandabackup@VIRTCENT18 ~]$ ssh lb1 amandabackup@lb1's password: Last login: Fri Dec 31 10:57:05 2010 from 192.168.1.40 ######################################################### # SUMMITNJHOME.COM # # TITLE: LB1 BOX # # HOST: VIRTCENT01 # # LOCATION: SUMMIT BASEMENT # ######################################################### check to see if the key exists in authorized_keys [amandabackup@VIRTCENT01 ~]$ grep -f id_rsa_amdump.pub ~/.ssh/authorized_keys it didn't so cat it into authorized_keys [amandabackup@VIRTCENT01 ~]$ cat id_rsa_amdump.pub >> ~/.ssh/authorized_keys check again, just to make sure that it's there [amandabackup@VIRTCENT01 ~]$ grep -f id_rsa_amdump.pub ~/.ssh/authorized_keys ssh-rsa BlAB3Nza/FAKE-KEY-DATA--KEY-DATAKfMq4DDa0xaKb/FAKE-KEY-DATA--KEY-DATAsoqCu/boKNa/FAKE-KEY-DATA--KEY-DATAp1n9TcDtxm2XFHcOKUw2/14/bz1pWNDI/FAKE-KEY-DATA--KEY-DATAr9951JdK7Ny6lk/FAKE-KEY-DATA--KEY-DATA1/FAKE-KEY-DATA--KEY-DATAwh2dmgyxI9N69x3ypvWcGWShZw1BCJI06j5qIxvin99/FAKE-KEY-DATA--KEY-DATA It is. so good so far.

mount.cifs with kerberos
by Adam Wead 04 Jan '11

04 Jan '11

Hi all, Has anyone been able to mount windows shares with mount.cifs using kerberos credentials? I can get a kerberos ticket at login or use kinit and then connect via smbclient: > kinit username > smbclient -k \\server\share I'd like to be able to mount the share like this: > mount.cifs //server/share /mnt -o user=username,sec=krb5 The above command returns: mount error 95 = Operation not supported Using sec=krb5i returns: mount error 126 = Required key not available Some of the stuff I read said that mount.cifs doesn't support kerberos yet, but that wasn't recent.

centos6 filesystem size limit
by Robert Arkiletian 03 Jan '11

03 Jan '11

I just read the rhel6 filesystem size limit. http://www.redhat.com/rhel/compare/ It says 16TB limit for ext4 (same as ext3)?!?! I thought ext4 was supposed to support 1EB ( ~ 1 million TB) limit. That was one of the main advantages of rhel6. After a little more digging all I found was that the user space formatting tools (mkfs.ext4) only support 32bit filesystems (not 48bits). I'm surprised about this, I thought people would be waiting for >16TB support in rhel6. Does anyone know if this is going to change in point releases of rhel/centos6?

The problem with VMWare Server is that it is a discontinued product for longer time and they don't provide us with a suitable replacement. So our institute had to switch to VMWare workstation that can be run as a server, too. I'm running CentOS 5.5 as the Host OS and 5.5 and RHEL6beta as guests.

No ices for icecast ?
by Keith Roberts 03 Jan '11

03 Jan '11

Hi, and a Happy New Year to everyone. I have followed this tutorial to install icecast on Centos 5.5, http://www.howtoforge.com/linux_webradio_with_icecast2_ices2 but cannot find the ices package for sending the audio to icecast for it to stream. I would like to send the data as mp3, if there is a suitable program to do this. Has anyone on the list done this on Centos?

GRUB Boot Menu

On Centos 5.5, is there a way to skip the countdown screen 'booting xyz OS in x seconds', and make GRUB show the menu of all the bootable OSes, and just stop there?
