RHEL 7: No Output From Ip Commands

Hi,

Please view this log below. Can you tell me the reason why I can not ping to server (server hang, or network services down, ...)

Thank you.

Code:

[root@mediaserver ~]# cat /etc/redhat-release 
Red Hat Enterprise Linux Server release 5.7 (Tikanga)
[root@mediaserver ~]# uname -a
Linux mediaserver 2.6.18-274.el5 #1 SMP Fri Jul 8 17:36:59 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux
[root@mediaserver ~]#

log file: https://onedrive.live.com/redir?resi...int=file%2ctxt

At May 20 10:26:11, I reset server.

I am taking a Linux class and am doing horribly, I just do not understand Linux. Can anyone please tell me how to create a shell script containing the `echo`, `whoami`, `groups`, and `pwd` commands?

I can do these as individual commands but cannot figure out how to do this in a shell script and get the output to produce output similar to the following:

You a
root
You are a member of the following groups:
root bin daemon sys adm disk wheel
Your current working directory is:
/tmp

My hair is getting thinner and grayer because of this.. Please help!

I use Redhat 6.3 , when I install run "yum install vsftpd" , it pops the following error, does it mean the library is not support , I have to update the kernel ? thanks

I am using the following two commands to output CPU and RAM usage on a Linux machine.

Code:

/bin/grep 'cpu ' /proc/stat | awk '{usage=($2+$4)*100/($2+$4+$5)} END {print usage "%"}'

/usr/bin/free | grep Mem | awk '{print $3/$2 * 100.0 "%"}'

My problem is that the output is like this

Is there a way to output a single number? For example

Thank you

Can you guys advise on how to resolve this? We have a machine (RHEL 6 32bit 2.6.32-504.8.1.el6.i686) that boots to a black screen. I can SSH into it from my machine, but when you're physically at the machine it just displays a black screen.

I have tried booting from the previous 2 kernels, but still get the black screen.

I am assuming something got hosed with the video stuff? Its an ATI Radeon 4000series card. Should I install the ATI driver from their website and try? We have never had to do that with these machines though.


Also, when running a yum update, we receive this error. I'm not sure how to resolve this and if resolving this will fix the video issues.

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Heres after running yum update --skip-broken:

I just installed Redhat 7 and try to config the network , add the IP address to network card , but I got the problem.

I modify the file /etc/sysconfig/network-scripts/ifcfg-enp0s3 , the configuration is as below , and then reboot .

DEVICE="enp0s3"
NETBOOT="yes"
HWADDR="08:00:27:15:38:B7"
TYPE="Ethernet"
BOOTPROTO="none"
NAME="enp0s3"
UUID="462f4834-4fe7-43a7-84e7-83b2722e94c1"
ONBOOT="yes"
IPADDR="192.168.1.1"
NETMASK="255.255.255.0"

After reboot , I use "ip addr show" still not shown the ip address , the ip address is still blank , would advise what is wrong ? thanks

Dear Friends ,

My date value shows One hour ahead from the present time in BDT . I stay on Asia/Dhaka zone and +6.00 . Please look @ the below output :

------------------------------------------------------------
[root@pbldc-ntpsrv Asia]# cat /etc/sysconfig/clock
# The ZONE parameter is only evaluated by system-config-date.
# The timezone of the system is defined by the contents of /etc/localtime.
ZONE="Asia/Dhaka"
UTC=true
ARC=false
-------------------------------------------------------------


But , My problem is , the below Date command output shows 'BDST' instead of 'BDT' .
------------------------------------
"[root@pbldc-ntpsrv Asia]# date
Sat May 9 16:59:37 BDST 2015
-------------------------------------
But it should be :

---------------------------------
[root@pbldc-ntpsrv Asia]# date
Sat May 9 15:59:37 BDT 2015
---------------------------------

---------------------
[root@pbldc-ntpsrv ~]# date +Z
BDST --Should be BDT
[root@pbldc-ntpsrv ~]# date +%z
+0700 --Should bt +0600
[root@pbldc-ntpsrv ~]#

------------------------------------
