I would like to be able to run commands from a windows machine (using some tool ) and run commands in linux machine and retrieve results of those commands.
I have a powershell code which connects to remote windows systems, I want to be able to retrieve system info from linux machines as well. Is this possible?

This is in relation to this question:
 powershell to linux.

I am attempting to find a place to pay for advertising for technical  courses we are giving , it has to do with Linux in general . Where do you think a good place it to PAY for an ad for this kind of training ??/


thanks

I have linux server and i want to count pdf pages is colored or bw.

i have used imagemagic but it takes serverd down so can you help me with alternative way?

Hi friends,

I'm in (preemptive !) need for some bootable antivirus rescue disk for offline scanning of Linux systems - preferably a flavour that could be banned onto a bootable USB stick and with good test results ...

Any recommendations ?

Hi Experts,

I want to connect to multiple redhat machines from Windows powershell and retrieve configuration info from redhat systems.

What is the best way to achieve this. ?

I know there is a putty tool to connect to linux systems but is there a way to retrieve info from redhat machines like CPU, memory etc.

I would really appreciate if you could help..

Hi, some time ago I have cloned and installed this project github.com/openshift/openshift-ansible on the VMs where SELinux was disabled
And now I can see this doc openshift.org , where they say: Security-Enhanced Linux (SELinux) must be enabled on all of the servers before installing OpenShift Origin or the installer will fail.
So my question is how does Openshift play with SELinux? What is the algorithm of this play?

Hi All,

After the filesystem issue on my VCSA v6.5, I suddenly unable to login to the server with the below error:

A server error occurred.
Unable to log in because you do not have permission on any vCenter Server systems connected to this client.
Check the vSphere Client server logs for details.

Select all Open in new window

I can login using administrator@vsphere.local but not anything with AD integrated account.

Here's the chronological order:
Observation:
==========

-- vCenter server down
-- not pingable.
-- Issues seen in the ESXi host which the vCenter VM is residing on :

2017-06-17T11:07:34.592Z: [scsiCorrelator] 2630366567703us: [esx.problem.storage.connectivity.lost] Lost connectivity to storage device naa.6000eb3311ab55e3000000000000040f. Path vmhba37:C0:T9:L0 is down. Affected datastores: "PRODSQL01_Backup"..

-- vCenter VM hangs in the black screen - where it goes into the single user mode.

Reason :
======
-- The root filesystem has mismatching inodes.

Action taken :
=========
To fix the issue we went ahead and cleaned the filesystem bad blocks.

executed the below commands :
1. Check the filesystems :

/sbin/blkid

2. Run the e2fsck against the filesystem for root

e2fsck /dev/sda3

3. Fix the inodes when asked for it
4. Once process completes, reboot the virtual machine.

This is using an Amazon ami 64-bit EC2 instance. This is an web application server that do some routine registration. I am thinking of gathering and backing up some of the log files for further auditing purposes. please see the list of log files:

/var/log/audit

    Monitor default audit rules/custom audit rules

/var/log/messages

    Not entirely sure if I would be able to glean any intrusions/modification from this but this would give me an idea of the system state on start-up

/var/log/secure & /var/log/wtmp

    Authentication attempts/fails

"/var/log/httpd/ssl_error_log*" & "/var/log/httpd/ssl_access_log*"

    Access and error log for webpage (not sure if this would help holding onto these...but it could give an insight if a random IP kept hitting my webpage. Wouldn't prove anything but might warn?)

I am thinking of compress and backing up as an additional copy, let's say once every week. btw, please shed a light on how can I achieve this probably with the use of cron job?

Thanks in advance.

What is a quick but definite test to run from the Linux command line to check if dns requests are being hijacked. The test should not require having to change the dns servers for the device that the test is being run from.

I had this question after viewing Network issues with Linux Bonding and Cisco 2960-S.

Old, question... but its talking about bonding cisco and linux sides.  I have successfully setup linux bonding (mode 4 - lacp ) with cisco switches ( 4948 ) in the past.  But what i want to do now, i dont know enough about cisco to do so.  I am a devop guy, so networking, especially cisco gear, is a little outside by knowledge base.  

Goal:
setup some kind of bonding on the cisco side that allows me to first plug a server in, boot it, install from the network, then reconfigure it into a bonding setup.... automatically.

I have a bunch of servers i am trying to automatically deploy.  i want to boot them up with nothing on them, use the ubuntu MAAS (metal as a service ) to install an OS on them, then use ansible to connect to the newly installed server to then create the interface bonds.  At that point, i would then like the cisco switch to use lacp( or some type of similarly useful bonding ).  

The issue is a chicken/egg scenario.  You have to create the port channels on the cisco and add the ports to them and set them for lacp( as far as i know, and why i am asking this ).  On the linux side, you then need to setup bonding and set the mode to 4.  Since i am doing everything automagically using MAAS and ansible ( tested and working ).  It SEEMS i cannot setup the …
