Finding your processes to learn how to determine the job numbers

`Finding your processes' to learn how to determine the job numbers of your background processes.

http://infohost.nmt.edu/tcc/help/unix/suspended.html

http://infohost.nmt.edu/tcc/help/unix/ps.html

• To find the job numbers of all the background jobs you are running, type:

          % jobs

  The job numbers will be shown in square brackets ([]), followed by the notation ``Stopped'' (for suspended jobs) or ``Running'' (for jobs that are still executing).
• To find out all the process ID numbers of processes you are running, type:

          % ps -gx

  Here is an example of output from this command:

            PID TT STAT  TIME COMMAND
          12030 p5 S     0:01 -csh (csh)
          12068 p5 T     1:46 emacs foo
          12788 p5 R     0:00 ps -gx

  The first column is the process ID. The second column tells what terminal is controlling it (in this case, ttyp5). Next comes the current status (S for sleeping, T for stopped, R for running). The next column tells how much time it has spent.

Resuming a suspended process

http://infohost.nmt.edu/tcc/help/unix/fg-bg.html

• The bg command can be used to resume a suspended process in the background. When used with no arguments, the bg command will continue the last suspended job. To resume job number 2, you would type the command:

          % bg %2

• The fg command resumes a suspended process in the foreground. For example, to resume job 1 in the foreground, you would type this command:

          % fg %1

• You can also resume suspended processes by just typing a percent sign (%) followed by the job number. For example, the command %1 would resume job 1 in the foreground. This command:

          % %2&

  would resume job 2 in the background, because it ends with an ampersand.

Kill a suspended process as shown below:

       % kill %1

NDES Disable Password Requirement.

I've read a few blogs and articles that say;

"There is no way for Cisco devices to supply the required password to enroll with NDES/MSCEP, so you need to disable the requirement for a password."

This is NOT TRUE, however the whole point of issuing certificates via your PKI infrastructure, is that it can scale dramatically. If you are creating passwords and embedding those passwords in all your enrollments, it can get a little unwieldy. So it may be sensible to remove the password requirement.

1. Windows Key+R > regedit {Enter} > Navigate to;

HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Cryptography > MSCEP > EnforcePassword > EnforcePassword

To disable change the value to 0 (zero).

Below you can see the difference, with the password requirement enforced, and without.

2. Restart the Certificate Services Service;

net stop certsvc net start certsvc
