Installing updates on Linix servers

I have two linix servers in our network. I believe the are Suse , but I don't know how to be sure?
What I like to do is to be able to update the OS. I tried running a the commend Yum on the terminal and got a good amount of lines back. I was not sure if they are the updates that have already been installed or they are the ones that are now available to be installed. I noticed that some of the results were bold. Also, how do I can I distinguish between updates for the OS vs updates for some of the software that we have installed. ? In general it would be good to know how to use the Yum command altogether.
I am more concerned about the shell lock bash, but being able to figure out the above should resolve that. Thank you

ls /etc/*-release
cat /etc/*-release

Is it SUSE? openSUSE?

Then:
zypper ref; zypper up
all good? reboot if it says so...

rindi

If "yum" works on those systems, they aren't SUSE. SUSE uses zypper as mentioned above, not yum... Or you can also use Yast.

yum is mainly used on RedHat or RedHat based OS's, like CentOS, Oracle Linux etc.

First we need to confirm what type of system asker has.

netcomp

ASKER

Ok, So I got the same output for both.

[root@ourserver ~]# cat /etc/issue
CentOS release 6.5 (Final)
Kernel \r on an \m
2.6.32-431.20.3.el6.x86_64 ( i got this by doing a uname -r command I found online)

So now, I like to know if any of that needs an update and also to know if any of the software that we installed in OS needs updates or if updates are available for them as I mentioned above. I am also concerned about Shelllock Bash? Thank you!

On one of them

But I am not sure what Ynm update does. Does that update the OS or does it udpate all the software that is installed. Can I pick and chose? Also, how do I know what updates have already been done.

yum clean all
yum install yum-downloadonly
yum upgrade --downloadonly (repeat until it comes out clean with all downloaded)
yum upgrade
reboot

(with 6U6 in sight you need to run "yum upgrade" as couple of packages are renamed and will be skipped with yum update)

Ok, when I do Yum check-update, I got the following result, but nothing bout the Kernal update or nothing about any Shelllock Bash udpate.

bash-4.1.2-15.el6_5.2 on CentOS 6.5 is not vulnerable for CVE-2014-6271.

Check your bash version with

# rpm -qv bash

Open in new window

how do I find out what is at.x86-64. Is that the bash update or are you saying that's for updating the kernal? Any way to get explanation of what each update is. Sorry, come from the Windows word, but have command line experience with Widndows/Cisco and ...., but new at this.

at command runs programs at given time. It's independent package from bash.

If you want to get info about installed package, use:

$ rpm -qi packagename

Open in new window

And don't wait with updating all packages (yum update). After few minutes you'll have up-to-date system, with all known vulnerabilities fixed. It's especially important for kernel.

penguins_rule

The version of bash on your system bash-4.1.2-15.el6_5.2 has been fixed to correct the bash shell shock vulnerability. It created a problem with the at and batch commands where they would no longer run. So that is fixed in the at-3.1.10-44.el6_5.2 update.

I agree with slubek that you should update all packages.

Thanks for all the inputs. So, no easy way to see if the Kernal needs an update or not. I guess not in my case because its not being listed. ? Also, is a reboot needed after the updates?
