To my understanding, when you install centos-7 with options ServerGUI or
GNOME Desktop and leave the system for long time locked, you will notice
that CentOS slips into textual interface mode and you will not be able to
get GUI which means, you can login to the system and cannot see GUI screen.

I have found the following steps on google, which helped me get through
this problem

systemctl disable gdm.service
systemctl enable lightdm.service
systemctl set-default graphical.target

First command was successful, second one error'd out. Not sure what to do,
i reverted back the first command and executed the third command and
rebooted. All worked fine !

Below is the log -

[root@buildhost ~]# systemctl disable gdm.service
Removed symlink /etc/systemd/system/display-manager.service.

[root@buildhost ~]# systemctl enable lightdm.service
Failed to execute operation: Access denied

[root@buildhost ~]# systemctl disable gdm.service

[root@buildhost ~]# systemctl enable gdm.service
Created symlink from /etc/systemd/system/display-manager.service to
/usr/lib/systemd/system/gdm.service.

[root@buildhost ~]# systemctl set-default graphical.target
Removed symlink /etc/systemd/system/default.target.

I think, the last command made sense to me.

I did the following and rebooted, all worked fine. I am not sure if that is
the solution.

Re: [CentOS] CentOS-7 Screen black after boot

[Venkata Balaji N]

Hello,

I have the same problem again today with CentOS-7.

I re-installed with GNOME Desktop and also configured two VMs in it, all
was working fine and i left the system locked overnight. When i tried to
unlock the next day morning, screen only shows up black. Again, i cannot
see the GUI. I can login to the system though.

Any help would be appreciated here.

Thanks,
VB

Sorry, i am not sure what graphic card, i am using. But, all i could say is
that, it was working absolutely fine and all-of-a-sudden displaying a blank
screen.

If this was the problem right from when i installed the software, that is
understandable. Not sure, why it worked before and not after.

By googling, i found out that it could be a problem with configuration of
some files in /etc/X11/ location ??

Below are the messages from /var/log/Xorg.0.log file, does these mean
anything ?

[CentOS] CentOS-7 Screen black after boot

[Venkata Balaji N]

Hello Community,

This is my first ever email to CentOS community. Firstly, CentOS is a great
open-source operating system. I have been using it for years and
recommending the same for production use to our customers.

I have installed CentOS-7 operating system couple of days ago and
everything was working fine. Yesterday, the screen got struck and the whole
system was unresponsive, after a long wait, i have restarted the system.
Since, then, i can only see the black screen and GUI is not coming up.

I can remotely login to the system from Putty and can operate without any
issues, the only issue is that GUI is not coming up.

I have installed CentOS-7 server-GUI. Any help would be appreciated here.

[CentOS] Problem in migrating DRBD from CentOS4.4 to CentOS5.5

[Balaji]

Dear All,

Previously we have used
CentOS4.4 release with Supported Cluster Suite and DRBD 8.0.0 
Active/passive (failover)

We have build the DRBD 8.0.0 Source in CentOS4.4 Setup
We have configured the DRBD Resource with default OS installed LVM 
(/dev/mapper/vgroot-LogVol00 and /dev/mapper/vgroot-LogVol01) Partition 
and its working fine

Partition Tables are listed below
=
FilesystemSize  Used Avail Use% Mounted on
/dev/mapper/vgroot-LogVol02
  3.0G  1.1G  1.7G  39% /
/dev/mapper/vgroot-LogVol03
   11G  8.5G  1.7G  84% /usr
/dev/hda1 494M   37M  432M   8% /boot

/dev/mapper/vgroot-LogVol00
   13G  161M   12G   2% /backup

Currently we are migrating to CentOS5.5

Step 1: We have migrated to CentOS5.5 Alone and Used Older DRBD 8.0.0 
Version

We have build the DRBD 8.0.0 Source in CentOS5.5 Setup
We have configured the DRBD Resource with default OS installed LVM 
(/dev/mapper/vgroot-LogVol00 and /dev/mapper/vgroot-LogVol01) Partition
The DRBD Meta data created successfully, but DRBD Module Load failed

Errors are listed below
===
[r...@corviewprimary user]# service drbd start
Starting DRBD resources:Can not load the drbd module.

[r...@corviewprimary user]#

[r...@corviewprimary user]# modprobe drbd
FATAL: Error inserting drbd 
(/lib/modules/2.6.18-194.3.1.el5xen/kernel/drivers/block/drbd.ko): 
Invalid argument
[r...@corviewprimary user]#

Step 2: We have updated DRBD from 8.0.0 to 8.3.8

We have build the DRDB 8.3.8 Source in CentOS5.5 Setup
We have configured the DRBD Resource with default OS installed LVM 
(/dev/mapper/vgroot-LogVol00 and /dev/mapper/vgroot-LogVol01) Partition 
and its not working

We got the following errors on meta data creation
=

Dear All,

We are running RHEL4 Update 4 AS IA-64 on a HP rx6600.

When we attempt to run a program using /usr/bin/gdb we are not able to 
hit the break point set.

We need the following details
1. How to run a i386 compiled program in IA64 bit environment using gdb 
and be able to hit break points?

2.How do we catch a running process in gdb and apply a breakpoint in our 
setup.


The code of C program in question is given below
#include stdio.h
int count=0;
void printString();
int main()
{
printf(unlock\n);
while(1) {
//do nothing
printString();
//break;
}
return 0;
}

void printString() {
count++;
printf(count = %d\n,count);
return;
}

The above c code compiled in i386 environment and the IA64 bit server in 
which we are running this program are attached.

Thanks in Advance,

Did you try my previous suggestion of adding selinux=1 enforcing=1 
to the kernel line in your grub.conf?  While you're at it .. make sure 
that you're editing /boot/grub/grub.conf .. most people use 
/etc/grub.conf .. which is a symlink to /boot/grub/grub.conf .. if the 
symlink is broken and /etc/grub.conf is an independent file, you can 
edit it all day and not affect grub.  Same goes for 
/etc/selinux/config which is the real file, and /etc/sysconfig/selinux 
which is what most people edit.

What is the output of rpm -qa | grep -i -e selinux and cat 
/proc/cmdline ??  Are you using a CentOS supplied kernel, or your own 
kernel?  I suppose you would try adding selinux=1 enforcing=1 to the 
end of your kernel line in your grub.conf, although I've never needed 
to do that to get SELinux to activate.

Use getenforce to determine the current status of selinux.  Look in
/etc/selinux/config for details of policy being used - e.g. targeted.
 


 2. Selinux Customize my own policy
   


man setsebool
man getsebool

These will help you modify options in the supplied policies.  For
example, use getsebool -a | grep http to list all selinux options and
filter the list for those pertaining to http.  You can of course create
your own policy and local customisations based on audit logs etc, but
I've not ventured down this path myself.  Others on the list will be
able to assist if you need to go that way.

Hope that gets you started :)

Cheers,

[CentOS] Ethernet Channel Bonding Clarification is Needed

[Balaji]

Dear All,
I have configured Cluster Suite with 2 servers
Server 1 : 192.168.13.110 IP Address and hostname is primary
Server 2 : 192.168.13.179 IP Address and hostname is secondary
Floating : 192.168.13.83 IP Address (Assumed by currently active server)

I have configured Ethernet Channel Bonding in Each Cluster Nodes and 
Channel Bonding Configuration Details are
1) Created bonding devices in /etc/modprobe.conf filealias bond0 
bonding

 options bonding miimon=100 mode=1
2) Edit the /etc/sysconfig/network-scripts/ifcfg-eth0 and ifcfg-eth1 
configuration

 DEVICE=eth0
 USERCTL= no
 ONBOOT=yes
 MASTER=bond0
 SLAVE=yes
 BOOTPROTO=none

 DEVICE=eth1
 USERCTL= no
 ONBOOT=yes
 MASTER=bond0
 SLAVE=yes
 BOOTPROTO=none
3) Created a network script for the bonding device is 
/etc/sysconfig/network-scripts/ifcfg-bond0

 DEVICE=bond0
 USERCTL=no
 ONBOOT=yes NETMASK=255.255.255.0
 GATEWAY=192.168.13.1
 IPADDR=192.168.13.110
4) Reboot the system for the changes to take effect.

After i am rebooted both the server then cluster node becomes simplex 
and Services are started on both the nodes

The cluster output in primary node

Member Status: Quorate

Member Name  Status

secondary   Offline

Before Ethernet Channel Bonding cluster services are active in one node 
and other nodes acts as passive node.
But after Ethernet Channel Bonding cluster services are active on both 
the nodes


I don't know what is the problem and is their any configuration is 
required in cluster configuration file and

cman is working only with eth0 interface

Can some one throw light on this peculiar problem

As stated by Karanbir your processor requires rpms that end in
ia64.rpm not i686.rpm or i386.rpm or x86_64.rpm though noarch.rpm is
acceptable.

[CentOS] Discrepancy between df and quota commands

[Balaji]

Hi All,

There is some discrepancy between what quota reports and what du reports

-bash-3.00$ cat /etc/redhat-release
CentOS release 4.4 (Final)

-bash-3.00$ pwd
/home/corview

-bash-3.00$ df .
Filesystem   1K-blocks  Used Available Use% Mounted on
/dev/mapper/vgroot-LogVol01
 10095152586932   8995404   7% /home

-bash-3.00$ du -sh .
19M .

-bash-3.00$ quota
Disk quotas for user corview (uid 934):
Filesystem  blocks   quota   limit   grace   files   quota
limit   grace
/dev/mapper/vgroot-LogVol01
968480* 90 100none 268   0   0


As shown above du says only 19MB is occupied by user corview( No big
files of corview are present in /tmp/ or /var/ )
But quota says 968480 out of  100   is used.



-bash-3.00$ id
uid=934(corview) gid=934(corview) groups=19(floppy),934(corview),935(admin)
-bash-3.00$ grep 934 /etc/passwd
corview:x:934:934::/home/corview:/bin/bash
nbiperf:x:946:934::/home/nbiperf:/bin/bash
nbibill:x:947:934::/home/nbibill:/bin/bash
rilbill:x:948:934::/home/rilbill:/bin/bash

So, no other user with id 934. and data in other users who are in
corview group is also very small.

lsof hasnt revealed any thing.

How do I know which file(s) is(are) eatig so much.?

I found a peculiar problem
-bash-3.00$ pwd

-bash-3.00$ ls -l

[CentOS] CentOS4.4 - Not booting up

[Balaji]

Hi,
 I've been using an CentOS4.4 version.
All was well till 2 days back. Suddenly when the PC was booted-up, it
wouldn't  bootup. It gets stuck displaying the following message.

exec of init (/sbin/init) failed !!!: 80
umount /initrd/dev failed: 2
Kernel panic - not syncing: Attempted to kill init!

I entered the rescue mode and attempted
chroot /mnt/sysimage
It spitted an error

chroot : cannot execute /bin/sh: Accessing a corrupted shared library.

I tried to google-out the problem in vain

Any clues as to whats the problem and the remedy?

TIA,
Balaji

[CentOS] Regd: Ethernet Channel Bonding issue in Cluster

[Balaji]

Dear All,
I have configured Cluster Suite with 2 servers
Server 1 : 192.168.13.110 IP Address and hostname is primary
Server 2 : 192.168.13.179 IP Address and hostname is secondary
Floating : 192.168.13.83 IP Address (Assumed by currently active server)

I have configured Ethernet Channel Bonding in Each Cluster Nodes and 
Channel Bonding Configuration Details are
1) Created bonding devices in /etc/modprobe.conf filealias bond0 
bonding

  options bonding miimon=100 mode=1
2) Edit the /etc/sysconfig/network-scripts/ifcfg-eth0 and ifcfg-eth1 
configuration

  DEVICE=eth0
  USERCTL= no
  ONBOOT=yes
  MASTER=bond0
  SLAVE=yes
  BOOTPROTO=none

  DEVICE=eth1
  USERCTL= no
  ONBOOT=yes
  MASTER=bond0
  SLAVE=yes
  BOOTPROTO=none
3) Created a network script for the bonding device is 
/etc/sysconfig/network-scripts/ifcfg-bond0

  DEVICE=bond0
  USERCTL=no
  ONBOOT=yes NETMASK=255.255.255.0
  GATEWAY=192.168.13.1
  IPADDR=192.168.13.110
4) Reboot the system for the changes to take effect.

After i am rebooted both the server then cluster node becomes simplex 
and Services are started on both the nodes

The cluster ouput in primary node

Member Status: Quorate

Member Name  Status
--- ---  -
primary Online, Local, rgmanager
secondary  Offline

Service Name Owner (Last)   State
-  -   
Service  primarystarted

The cluster ouput in secondary node

Member Status: Quorate

Member Name  Status
--- ---  -
primary Offline
secondary  Online, Local, rgmanager

Service Name Owner (Last)   State
-  -   
Service  secondary started

Before Ethernet Channel Bonding cluster services are active in one node 
and other nodes acts as passive node.
But after Ethernet Channel Bonding cluster services are active on both 
the nodes

I need to solve the following issue and services are run only active node.

Can some one throw light on this peculiar problem

[CentOS] Regd: Iptables SNAT issue in Cluster Suite Setup

[Balaji]

Dear All,

I have configured Cluster Suite with 2 servers
  Server 1 : 192.168.13.110 IP Address
  Server 2 : 192.168.13.179 IP Address
  Floating : 192.168.13.83 IP Address (Assumed by currently active server)

I want all snmp packets going out through the active server to be 
stamped with floating IP

So i have added a iptables rules as
  iptables -t nat -A POSTROUTING -p udp -s 192.168.13.179  --dport 161 
-j SNAT --to-source 192.168.13.83:161
iptables -t nat -A POSTROUTING -p udp -s 192.168.13.110  --dport 
161 -j SNAT --to-source 192.168.13.83:161


I have written a script to continuously poll an agent using snmpgetnext.
This script works for some time and then snmpgetnext fails giving the

[CentOS] Regd: Iptables Source NAT

[Balaji]

Dear All,

 I am using the following rules in firewall scripts

   /sbin/iptables -F INPUT
   /sbin/iptables -F OUTPUT
   /sbin/iptables -F FORWARD
   /sbin/iptables -F RH-Firewall-1-INPUT

   # Default Rule
   /sbin/iptables -P OUTPUT ACCEPT
   /sbin/iptables -P INPUT  ACCEPT
   /sbin/iptables -P FORWARD ACCEPT

Rsync Source NAT rules is
   iptables -t nat -A POSTROUTING -p tcp -s 192.168.13.179 --dport 
873 -j SNAT --to-source 192.168.13.83:873


192.168.13.179  is  eth0  ipv4 ipaddress  and 192.168.13.83 is eth0 
ipv6 ipaddress



The following rules is working fine
But the problem is at every rsync trigger we will restart the iptables 
and firewall scripts, then only it will works
If the services are not restart then it will send the following error 
message

rsync: failed to connect to 192.168.13.100: Connection timed out (110)
rsync error: error in socket IO (code 10) at clientserver.c(94)

I need to solve the following iptables and firewall restart issue.

192.168.13.83 does not look like an ipv6 address.

I would like to help, but i honestly did not understand the problem.
If possible, please elaborate.

[CentOS] Reg:Checking HDD Badblocks on kickstart CentOS installation

[Balaji]

Hi All,
  Is there a way to check the harddisk health before CentOS installation.?

One way I used to do was by using --badblocks check in ks.cfg file while
using RH 7.2.

   This is not working (atleast not with the same syntax as in RH 7.2) in
CentOS.
   Is there an alternate (correct) syntax or is there a new (better) way
to check harddisk health before CentOS installation?

Please help me and it is very urgent requirement for me
