== Basic Operating System Information -- Linux (any distro) ==

**1.** Is the system with the problem you're reporting actually on a //current support contract//?

  * If **no**, contact your PARSEC Account Representative before contacting the PARSEC Technical Support Team.\\   See [[How To Initiate a PARSEC Tech Support Call]] for full information.\\

  * If **yes**, proceed to Step 2 below...

**2.** What is the:

  - Version of Linux?
  - Serial number of the system?
  - Architecture of the system (X86, AMD64, Integrity, etc)?
  - How many CPUs (cores) in the system?
  - How much physical memory?
  - How long has the system been up?

All of the above can be displayed with either of these commands --

Just cut-&-paste the following long line (all of it) onto your shell's command line, then hit ''Enter'':

  sudo echo "" ; uname -a \
  ; lscpu | grep "\(op-mode\|CPU\|Core\)" \
  ; sudo dmidecode -t processor | grep "\(Serial Number:\|Family:\|Version:\)" \
  ; lsmem | grep ":" ; free -h

//Hint//: Use your mouse to select all four lines above.  When the whole command is selected, enter ''Ctrl/C'' to copy it to your paste-buffer.  Then go to your shell's terminal window logged, and enter ''Shift+Insert'' to paste this text into the command line... hit ''Enter'' to execute the command.

__or__:

Use this alias command (define it in your shell's init-script):

  $ alias sysinfo='sudo echo "" ; uname -a' \
                 + ' ; lscpu | grep "\(op-mode\|CPU\|Core\)"' \
                 + ' ; sudo dmidecode -t processor | grep "\(Serial Number:\|Family:\|Version:\)"' \
                 + ' ; lsmem | grep ":" ; free -h'

//Hint//: Copy/paste the four lines above into your shell's init-script, e.g., ~/.bashrc or equivalent.  Logout and then login again -- Then you can use the alias command interactively, as follows:

  $ sysinfo

In either case, you'll see something like this:

When you run either of these commands, just cut-&-paste the resulting output into an email message for us, typically in response to the PARSEC's introductory email, ''Subject: Case //XXXX// has been logged for //YourCompanyName// by //TechName//''.

Be sure that all of your email correspondence about this case includes the "Case //XXXX//" (where //XXXX// is your case number) as the first two words of the Subject: line.

==== Sending logs ====

Logs on your Linux system can be found generally under one of two places **/var/log** and/or **/var/adm**. In cases where log files are requested. Please create a tar archive with the appropriate logs and include it with an email to support. 

<code>
journalctl >/tmp/journal.txt
tar czvf /tmp/case-1234-linux-logs.tar.gz /var/log /var/adm /tmp/journal.txt
</code>

The output file will be **/tmp/case-1234-linux-logs.tar.gz** and this is the file we'll need. Use SFTP or FTP and grab the file then attach it to email or send it to us via our [[FTP server]].
