I am running an old kernel for my XEN VPS CENTOS 5.5 x86_64 - 2.6.18-164.el5xenI did a 'yum update kernel' but when I rebooted still the same. I have downloaded the version 'kernel-2.6.18-194.32.1.el5' I cannot find grub.conf in both etc and boot, yes grub is installed via yum.
View 7 Repliesim a having a problem whit the terminal on my CentOS 5.3.After i installed the kernel-xen and activate it at:/boot/grub/grub.conf.I tried to start a terminal from my root gnome sesion and it shows this error:There was an error creating the child process for this terminal.I know swithcing the kernel made the problem because when i use the old kernel the terminal works fine.and even when i tried to connect to my Centos server via ssh it shows an error after asking for password:Server refused to allocate pty.
View 9 Replies View RelatedI followed the instructions on this page ([URL]) in order to secure my sshd and prevent anyone form accessing the server directly as root. Therefore I changed the "PermitRootLogin yes" to "PermitRootLogin no" and restarted sshd. After that root access was denied directly but for some reason I am unable to switch to root from any of the normal user accounts with "su -" because I keep getting the "Incorrect password" errors. I am sure that the password is correct but for some, to me unclear, reasons I am unable to access the root account over SSH from a normal user account. I also noticed that after that I lost the ability to access the server as root over SFTP. why I am unable to generally use the root account after doing the named changes to sshd_config/ I am running CentOS 5.4 with the newest update.

And is there any chance to be able to switch from a 32 bit kernel to 64 bit kernel during the update? The hardware is capable of this.

I had a Centos 5.5 system working great...and then due to crazy curiosity, installed the kernel update. Did this through the graphical interface, uncheck all update other than kernel. It downloaded, installed fine..After reboot now all I get is GRUB_ and then nothing else! I waited 3-4 minutes and had to shut down system. Have been googling around but thought I will post it here as well..When I boot with Win7 and use Ext2fsd to check, the boot folder is empty. Not sure if this is because ext2fsd does not read boot folder or it got wiped out by the yum upgrade process.

djmack-5/19/2011-I have purchased an ASUS K52J (intel i7) laptop. I have installed Centos 5.5 (64 bit) from CDs. The I got all the updates and it's now up to 5.6. I have two problems.
(problem-1) - Using the GUI (System->Administration->Hardware) I can get to a Device Manager screen. It shows a JMC250 PCI Express Gigabit Ethernet Controller. Using the GUI (System->Administration->Network) I can only see the wireless (wlan0) as configured and active. The ethernet card is not seen as ether 0. I've seen there are downloads to solve this problem, however I've been 100% unable to do and or understand them. I don't know how to build the kernel and I don't have any source code. I only have the binaries (I think). Is there a version of the kernel that I can put on CDs that has understanding of the ether card I referenced above?
P.S. I've downloaded a binary fix and it says it needs 20 or so dependencies (I have zero idea how to get those).
P.S. I've downloaded a source fix and I couldn't get it to install (I'm not a linux kernel build knowlegable person). I don't have the source either.
(problem-2):As stated above I need direct (RJ45) access to the laptop. I currently have the wireless card working but I have no idea how to get this to work with httpd, ssh, scp.I can access things via a web browser right on the laptop. I cannot access this laptop via a web browser from any other box. I cannot access this box via ssh or scp.I disabled the firewall and I disabled the SELinux security.I am stumped as to why I cannot see this ASUS laptop via httpd and/or ssh/scp.I can ssh and scp to other linux servers but these servers cannot ssh or scp into this laptop.
I got a CentOS server + KDE from a server (which I had no contact until now), he had 2 HD's one for the system and another for files.
I brought the HD system home to try to make it run on a virual machine (VMware) so I can do some testing before you put in practice.
But already converted the VMware HD to the system, it tries to start but it shows some errors and in a message "kernel panic - not syncing: attemped to kill init"
I think the drivers are correct, has edited the file "/ etc / modprobe.conf" edited these entries equal to another I installed CentOS on VMware.

My root server is using CentOS release 5.2 (Final), kernel 2.6.26.5-rootserver-20080917a, SMP, 64-bit This Oops happened yesterday and before that it happened on March 14th of this year, and before that on January 31st of this year, so a repeating pattern. On the January 31st Oops, I just rebooted. On the March 14th Oops, I reformatted the two swap partitions as follows: mkswap -c /dev/sda2; mkswap -c /dev/sdb2 On this last Oops, I turned off the swap for 24-hours, then decided to turn it on again after doing the above mkswap again. During the previous uptime, I had dumpcap packet capture running, but this last reboot, I'm not going to run it.
One thing I always do is switch to the vmlinuz-generic(-smp) kernel in /etc/lilo.conf and build an initrd (see /boot/README.initrd for details). The "huge" kernel used by default is only meant for installing and not recommended for everyday use. It has a lot of drivers you don't need built-in and uses more RAM than the "generic" kernels.
still trying to find my feet and get to know Slackware. In one of my previous threads, 'things to do after installing' i was told the above message. When i installed, it used the huge kernel, but i'm unsure if that was the one that got installed. when i start slackware up, above the login screen it say, �wecome to Linux 2.6.37.6-smp (tty1)� I was wondering how to swich to the generic smp kernel, do I just change the vmlinuz to the desired, in lilo?
One of our F14 machines was originally set-up with the i386 Kernel. I found out it had a kernel crash and the person tried to fix it by reinstalling the kernel, unfortunately they installed i686. Now some of our software that was setup to work with i386 is not cooperating. Is there a way to switch from the i686 kernel to i386 without reinstalling the system?

I installed Centos 5.4 on my Pentium E5300 new comp, but I need IPX support in my work. It's simple - ipxutils and ncpfs from Fedora Core and new kernel with ipx support. I copied kernel config from /boot folder and activate ipx, ntfs support, and choose processor core 2 duo. New kernel (2.6.26) works OK, but I got one problem - when start it still shows message: "kernel: HUB 1.0:1.0 unable to enumerate USB device on port 1 (or 2, 3)" and stops after logging (text mode)
I got 2 USB devices connected - printer HP D5160 PhotoSmart and Scanner A3 USB Mustek, and I know scanner cause that messages but I don't understand why. Kernel config is the same like that from distro kernel (almost - ipx, ntfs and proc), but distro kernel doesn't do that. So I got 2 questions:
1. Why
2. What to do to stop that (disconnecting devices on boot time is not a solution)

i've tried making the switch before, but always end up running into some trouble that has me going back to windows. i recently installed ubuntu 10.10 and everything has been going fairly smooth, i've been using it for a few weeks with no complaints. no complaints, that is, until i try to upload files... my digicam shoots movies in avi format. i have no problem uploading these files to videos from vista, it works as it should. i cannot upload anything to videos from ubuntu. whatever i try to upload fails instantly.
i also cannot upload photos to photobucket, with the same outcome. the transfer appears to start, but fails immediately afterwards. the photobucket problem has me really intrigued, since it will upload some files directly from the hard drive, but most pics on the hard drive will still fail to upload, and all files on my sd card straight out of the camera fail to upload regardless, even though the computer reads the card and the files fine locally.

I just installed CenOS 5 on my server and am in the process of installing some software to the machine.
I understand repositories and was able to get it all set up for installation with the yum command.
My problem is that when I attempt the install, it says i need root access to install.
I tried using sudo commands to switch to root access, but after entering the password, it says my username isn't allowed root and that my actions will be reported.
I am the admin for the system and have total control, I just don't know how to switch to root in the terminal.
I recently installed Ubuntu desktop, since I had been running my server as Ubuntu Server on a guest OS on Windows 7 and never really used the Windows part of the computer. Since then, I've been unable to use the mouse in a graphical environment for longer than a few minutes without it starting to act crazy. The mouse moves around normally, but won't respond to clicks (left, middle, or right) but the keyboard shortcuts still work. I'm not sure if things have changed since I last used Gnome though, but Alt+Tab is not working for me either when this happens. Sometimes, the active window is even behind another window, and isn't pulled to the foreground.
After a bit of frustrated clicking and jamming of buttons on the keyboard, sometimes the mouse kind of starts working because I'll notice a right click menu open. But, I am still unable to move windows or click on them to bring them to the foreground, and my mouse presses only work on the current window. And then, eventually, after about a minute or so, it'll stop respond again too.
I saw in one thread that someone had dead spaces where he couldn't click, so he installed and ran Gnome and that fixed it, but I tried using Ubuntu Classic and it is still giving me the same behavior. I'm actually posting this message now in links, because I can't use Firefox or Chrome well enough when it's hidden behind other windows.
