CentOS 5 :: Installing X On System Messes Up SSH?
Dec 4, 2009
If I perform the following steps:
1. Start up a new Amazon instance running CentOS 5.2
2. Log in via ssh using a private key
3. Execute "yum -y groupinstall "X Window System"
4. Reboot
I am no longer able to log in:
janine$ ssh -i ~/.ec2/key.pem root@ec2-xxx-xxx-xxx-xxx.compute-1.amazonaws.com
ssh: connect to host ec2-xxx-xxx-xxx-xxx.compute-1.amazonaws.com port 22: Operation timed out
I see that the X install updates several openssh packages, but I have checked /etc/ssh/sshd_config before and after the install and it's not being changed. Besides, this is acting more like a firewall issue, but why would installing X have anything to do with that? And it's kind of tough to check and see if iptables has been started up after the reboot since I can't log in. I can't find any docs saying that I need to do any configuring after installing X; it seems like it's supposed to Just Work.

I'm trying to install vim-enhanced on a XenServer 5 system which is supposed to use CentOS under the hood. Being a debian user I'm not very familiar with the way packages work in CentOS. The problem is that the packages manager seems to do nothing. I assume that a repository is missing but I don't know which and how exactly to add it.
[root@icestation ~] yum install vim-enhanced
Loading "installonlyn" plugin
Setting up Install Process
Setting up repositories

I decided to install Ubuntu 10.04 under Windows 7, but once I got it installed, I switched back over to Windows 7 real quick to find my display stretched. I tried to change it, but Ubuntu had made the current display the highest setting, so it was stretched until I removed Ubuntu. I wish to reinstall it but do not want to deal with that again. What happened?

I am new to Linux and I am having a huge problem after install nfs-kernel-server. I run "apt-get install nfs-kernel-server". It runs and says it installs without errors, at least what I saw. Also the syslog was clean of errors related. Where the problem happens is when I try to start the NFS server and also on boot. When I start the service manually, it says starting portmap and ...something else. Then it gets to the point of saying it is starting the NFS server and crashes and I have no prompt. On some cases I can break out of it with (ctrl+c).
The problem that happens on boot...and this is only happens after nfs-kernel-server is installed. I reboot and I have no prompt. The only thing on the screen is a message complaining about something related to fsck, the odd thing is when I look to see if fsck has made any log outputs about fsck. When I cat the fsck log it says the log has no entries. The worst part is I have no way to log in from the console the machine gives me no prompt. I know it is something related to NFS because I have reinstalled the machine and it work perfect until I install NFS.

I'm running 11.2. My screen saver has been working fine since the begining in December, but now when I run VLC or fldigi my screen saver will kick on for only a few minutes then it will pop back to the log in screen as if I had moved my mouse or hit a key on the keyboard.
VLC about shows : gcc version 4.4.1 [gcc-4_4-branch revision 150839]
fldigi is latest version
I get a lot of these in var/log/messages:
unix2_chkpwd: gkr-pam: couldn't unlock 'login' keyring: 1
unix2_chkpwd: pam_env(gnome-screensaver:setcred): non-alphanumeric key 'alias sox=padsp sox' in /etc/environment', ignoring
unix2_chkpwd: pam_env(gnome-screensaver:setcred): non-alphanumeric key 'alias aumix=padsp aumix' in /etc/environment', ignoring
unix2_chkpwd: pam_env(gnome-screensaver:setcred): non-alphanumeric key 'alias timidity=timidity -Oe' in /etc/environment', ignoring
If I reboot, it works corectly until I run one of those two. Not sure about any other audio type of program. Bad updates, virus, or something else?

Hearing the praises about fastness of xfce all over the net i decided to try it for my fav ubuntu i rightaway installed xubuntu (without creating a bakup of the names of programs that were going to be installed which i generally do to fully remove any utility that i install for test) i understood that fast for xfce actually meant light(stupid me). now i switch back to gnome onlt to find xfce stuff like pacmn file browser and wicd to name a few. i removed the pacmn browser but when i remove wicd the default network manager does not show up in the task panel i would like to know:
1.how to get back to gnome'z default network manager AND
2.the list of utilities installed when xubuntu-desktop is installed

I come today with a nasty problem. My computer has a Intergrated ATI Radeon HD 3200 IGP. Now despite being a IGP its more or less its own GPU. Thing is I can't get the full power if I don't use the drivers (I do some thigns that need acceleration)
I recently came back to Ubuntu cause my Windows 7 DVD wont work anymore so I have to play with ubuntu again. Currently Im running 9.10 32bit (because 10.04 LTS doesn't want to work for me even after burning a clean CD-RW (one that has never been used or blanked))
Every time I try to install the driver for my card from the resricted drivers menu, when I reboot it causes ubuntu to screw up and wont go into X and stays in terminal. Its been awhile since I tried it but after just fixing my computer I don't feel like taking the risk.

I dual boot my ubuntu 10.04 with my windows 7, I had 4 partitions on my machine, 2 ntfs and 2 ext4 partitions. But I noticed I still had an unallocated 10gb on my hdd, I couldn't see this unallocated space from ubuntu, fdisk, gparted etc. So I used diskmgmt in windows to create the 10gb ntfs partition, when I restarted I couldn't boot into either windows or ubuntu. I used my livecd to reinstall grub and everything was fine until I booted into windows 7 and restarted. Again my grub has been messed up.

I have been running happily on Knoppmyth R5F27 (on Debian GNU 4.0/Etch) for a good long time. Everything has been operating well. My kids get to record their Mythbusters. Life is good. Tonight, though, I tried to make things better. And that was the mistake.
I read that we could use our PS3 to watch videos on Hulu. But, I needed a kind of proxy server or something to mask that I was using the PS3 browser. So, I thought I would install squid on the myth box.
I first tried apt-get install squid But, that didn't quite work. So, at a friend's suggestion, I ran: apt-get update Which had problems, too. Still, being a noob, I reran the apt-get install squid and a bunch of stuff came down. It has problems, too.
So, I turned back to apt-get update and realized there was a problem in sources.list. I updated it to have a more current repository and received the update. Then I realized that the apt-get for squid was pulling down resources for lenny. I struggled trying to kill the install for Squid. Failed. And then rebooted just to see if I have problems.
And I do. Mythbackend won't start. The command to do so produces a segmentation fault. Ditto for mythfrontend and mythtv-setup. I don't know what to do. Can someone help me roll this back to a stable setup of Etch? If you want to see my (very messy) attempt to install squid and update the system you can look at[URL]..

I have my FC11 system set up to automatically download and install updates. I had to reboot yesterday because of one of these updates. It seems that this update messed up grub. When I rebooted I only got the flickering cursor. So far I have tried the following using the rescue disk and executing chroot /mnt/sysimage
fdisk -l gives me this result :
I have /dev/sda, /dev/sdb, /dev/sdc
Boot flag is with /dev/sda1 which also has FIlesystem Linux, where the other I notice have filesystem Linux LVM (don't know if that is relevant).
I tried to restore grub.
grub
> find /grub/grub.conf
hd(0,0)
> root (hd0,0)
Filesystem type is ext2fs partition type 0x83
> setup (hd0)
and there were no error messages. However, no change when rebooting.
The device map says that
hd0 = /dev/sda
hd1= /dev/sdb
hd2= /dev/sdc
I also did a grub-install --recheck /dev/sda. All to no avail.
The following struck me as strange, but not sure how relevant :
- In grub, "find /boot/grub/grub.conf" gave me "file not found"; however, with ls I do see a /boot/grub/grub.conf and also a /etc/grub.conf
- This grub.conf file says that boot=/dev/sdc (where the boot flag is with /dev/sda) and all references are to (hd2,0) whereas the "find /grub/grub.conf" always gives me "(hd0,0)" as said above.
- There seems to be no /grub/grub.conf file on my system except under the /boot directory
- I have also tried resetting the boot flag to /dev/sdc with fdisk, but that did not help either.
- originally, I did set the system up on /dev/sdc by the way
Am just trying to guess now what other combinations I could try. I already tried in BIOS to boot from all the different devices. No luck.

I just installed 10.04 64 bit to a windows 7 64 bit. After the install wubi works fine (except it hangs for like 1 minute saying Try hd(0,0) NTFS5: no wubildr), but windows 7 cant connect to the internet anymore. if i run ipconfig, it lests my ethernet adapter, but says that no network connection avaiable, the troubleshooter advises to plug in my ethernet cable. (it is plugged in, the net from ubuntu works fine.) Heres the output from lspci, dunno if helps:

Background information: I need to install WinXP on my computer to use Spectraview II software for monitor profiling. Tried it under Wine, didn't work...thought about virtualization, but Graeme Gill (creator of Argyll) said that probably wouldn't work:
Quote: The problem is that emulators often don't implement hardware details properly or at all. There's no standard way on Linux to read/write the DDC, so there is no surprise that wine doesn't emulate MSWin's API's for this. It's doubtful that any of the VM's do either. USB can be an issue too, and some instruments may not work in an emulated environment. I already had Ubuntu 10.10 installed, so thought I'd try installing WinXP after, then recovering the MBR. Lots of headache.

The installer can't see my raid controller (I assume) as I'm getting the following error:"Error opening /dev/mapper/isw_jbhgjgjj_Vol0: No such device or address"It just sees them as 4 individual drives: sda, sdb, sdc and sdd.Please note that I have set up the RAID 5 in the controller bios interface and the image name is Vol0, which it seems that it tries to load but for some particular reason it can't.I have also tried different bios settings and nothing worked.

My problem is that I'm trying to install CentOS 5.4 x86_64 DVD ISO on Supermicro X7SBI server with installed Adaptec RAID 3405 controller.
I created RAID 5 array and is working fine (adaptec status says Optimal) but I can't install CentOS to that array (1.5TB size).
Whenever I try to install with: linux dd
I'm asked for a driver, which I have downloaded from Adaptec site and extracted contents to USB drive (in installation found as /sba1) which has now a lot of IMG and some ISO files on it.
I try to load (I simplified names) RHEL5.img, CENTOS.img... with x64 names (one exact name: aacraid driverdisk-CentOS-x86_64.img) and I always get the error message: "No devices of the appropriate type were found on this driver disk"
This is going on for a week now and I can't find the right driver or something I'm doing wrong to get install done.

I need your help urgently. I will shortly install Centos 5 on a HP DL380R05 E5420 Server with two HP 146GB 10k 2.5 SAS HP SP hard disks running hardware RAID-1. I am a newbie on CentOS, please advise me:
1. Do I need a Centos RAID device driver for hardware RAID-1 on the HP DL380R05 E5420 Server?
2. Should I use Centos i386 or Centos x86_64 in this case? Which one: CentOS 5.2 or CentOS 5.3?
3. Does Centos support Embedded NC373i Multifunction Gigabit network cards?
The following is my server's hardware configuration:
HP DL380R05 E5420 2GB Base AP Server(1) Quad-Core Intel Xeon Processor E5420 Two Embedded NC373i Multifunction Gigabit / 2 GB (2 x 1 GB) PC2-5300 Fully Buffered DIMMs (DDR2-667)/HP Smart Array P400/256MB Controller /Rack (2U)/Hot Plug Fully Redundant Fans Standard Two HP 146GB 10k 2.5 SAS HP SP HDD HP 1000W IEC C14 Cord RPS Kit

I am having new hardware and IDE driver for that hardware as drive disk image (it8213_centos53.img). CentOS 5.3 installation is working fine with drive disk image at USB and CentOS 5.3 at DVD. Our application uses CentOS 5.3 and we build a custom kick-start ISO for installations. Using that ISO client is going to install on all hardware boxes.
Note while installing :
a) No network connection is avalible.
b) No USB isavalible.
c) No floppy is avalible.
d) Only single CD-ROM is avalible.
So, is it possible to build single custom kick-start CentOS 5.3 ISO which contains dirve disk image and entire installation will be done using that image. If so please let me know the steps to build it.

I've been trying to install the Fuppes media server onto CentOS and have had a few difficulties. I had to do a build from the source (svn build 578), then configure, make and make install. So far so good.Once I try to run fuppes, I get the error:[ERROR] Failed to bind socket to : 8.15.7.107:0.The documentation I've searched so far suggests that there is a config file that needs to be set with the appropriate ip address, but the file doesn't exist as the program hasn't started up yet!

I'm trying to install CentOS 5.5 on an old Pentium 4 desktop PC I have, which is not being used for much other than being a MTA, and I want to migrate this functionality onto the CentOS platform for stability (Windows is a perpetual nightmare. I partitioned a spare 20GB to experiment with, and I want to install CentOS into here to play around with first so I can move my files around between Windows and CentOS, until I'm happy all of the stuff is gone, then I can scrub the Windows partition and claim the space for CentOS.
So, I've downloaded and burned the DVD and tried to install. I start the install with no args from the main install menu, and the process goes through some probing and then comes up with the "Welcome to CentOS" menu. I go through this, and then it tries to start X Server. It fails, and falls back to text mode. I get the "Welcome to CentOS" screen again, and then proceed through it. I set my keyboard layout to UK, then this message comes up at the bottom of the screen:
"_X11TransSocketINETConnect() can't get address for localhost:6001: Temporary failure in name resolution"
then on the next line: "Cannot open display :1" If I force the install to text, by typing "linux text" at the first menu, I get about the same way through, but the install just hangs doing nothing, and no disc access to the install disc.

I've noticed this happen with every CentOS installation I've done in the past and it's confusing me. On the software template screen select, I always select "Server" and leave the extras option unchecked, I also check "Customise now". The only things I choose are the editors (to get vi), Web server and server configuration tools (and this time also Java). I didn't select any GUI programs, yet it still installs things like X, GNOME components and also samba. Why does it do that? There no way they're needed for dependencies. Is there something I'm missing when selecting the software components? Why does it still install samba when I didn't select it from under "Servers" components? Or have I misunderstood what software selection does and it installs all those components regardless but doesn't automatically turn the services on?

I am an old days RH release user(from 6.x) and just switching back from Debian/Ubuntu to CentOS on some servers, but I can not understand the kernel update strategy currently enabled in CentOS.There are two boxes, with almost identical installation, but recently there was an auto update of kernel on one box. This auto update also seems to issue an auto reboot on the machine, which is unacceptable on server machines.

I am trying to do a basic install of CentOS 5.4 on my embedded computer. It is a Linutop 2 system with a AMD Geode 800MHz CPU and 512Mb Ram. Have installed an IBM 40Gb 2.5" HD for OS storage. I am doing the install procedure in text mode. Everything goes as planned until I get to the package selection.
1. Booting from (i386) DVD with "linux text" parameter.
2. Skipping media check.
3. Selecting "English" install language.
4. Selecting "DK-latin1" as keyboard layout.
5. Selecting "Remove all partitions and create default layout" and selecting "no" to modifying partition layout.
6. Selecting "yes" to configure "eth0" and mark to enable "IPv4" on boot.
7. Selecting DHCP for IP configuration and Manual host name.
8. Setting time zone to "Europe/Copenhagen".
9. Setting root password to a 16 digit alphanumeric pass-phrase.
10. De-selecting "Desktop - Gnome" (no other entries selected).
When the system is checking for dependencies, an exception
Traceback (most recent call first):
File "/usr/lib/python2.4/site-packages/yum/packageSack.py", line 426, in returnNewestByName
