How to stop / start services in boot time and install / remove / update SuSE SLES (Suse Enterprise Linux Server)?

Friday, February 6th, 2015

If you're long time Linux sysadmin but you haven't need to adminster SuSE Linux still and your company buys other business / company which already owns some SuSE servers and you need to deal with them, even though you're just starting up with SuSE Linux but you had already plenty of experience with other Linux distributions Fedora / RHEL / CentOS, don't worry set up / stop / start a service (daemon) to boot on Linux boot time is just the same as any other Redhat (RPM) Linux based distributions. it is done by multiple shell scripts located in /etc/init.d directory which can be manually stopped start by issuing the script with an argument e.g

suse:/etc/init.d# cd /etc/init.d/
suse:/etc/init.d# ./snmpd
Usage: ./snmpd {start|stop|try-restart|restart|force-reload|reload|status}

To configure how each of the /etc/init.d/ existent service boots you can the use good old /sbin/chkconfig (a script written in perl) – which you already know from Fedora / CentOS and other RPM distros.

1. Get a list of all enabled on boot SuSE Linux services

To get a list of all set up to run on boot SuSE server services with chkconfig:

suse:/etc/init.d# /sbin/chkfong –list

2. Stop / Disable a service in all Linux boot runlevels or in a concrete one

As you should know already in Linux there are multiple runlevels in which server can boot, under normal circumstances SuSE servers (as of time of writting) this article boots into runlevel 3, if you'r'e unsure about the runlevel you can check it with runlevel command:

suse:/etc/init.d# /sbin/runlevel
N 3

To stop a service on all possible boot runlevels – 1,2,3,4,5

suse:/etc/init.d# /sbin/chkconfig xinetd off

If you want to stop xinetd or any other service just for certain runlevels (lets say run-level 3,4,5):

suse:/etc/init.d# chkconfig –level 345 xinetd off

3. Start / Enable a service for a runlevel or all boot levels 1,2,3,4,5

To disable boot.apparmor on all boot runlevels – kernel enhancement that enabled to set a limited set of resources for services (good for tightened security, but often creating issues with some external server configured services).

suse:/etc/init.d# chkconfig boot.apparmor off

Or for single boot modes again with –level option:

suse:/etc/init.d# chkconfig –level 345 boot.apparmor off

suse:/etc/init.d# chkconfig xfs off

4. SuSE Linux Package management zypper console tool

If you need / wonder how to install /remove / update a service on a SuSE Linux server, take a look at zypper tool.
zypper is a command-line interface to ZYPP system management library.

To install a package / service with zypper the syntax is very much like yum, for example:

suse: ~# zypper install vim -emacs

will remove emacs editor and install Vi Improved

The equivalent of yum -y Fedora command in SuSE Enterprise Linux is –non-interactive option

suse:~# zypper –non-interactive install

In SuSE it is pretty annoying when you're asked for accepting licensing on some proprietary (external vendor) non-free software packages to get around this:

suse:~# zypper patch –auto-agree-with-licenses

To keep the SuSE server up2date – i.e. SLES equivalent of CentOS's yum update && yum upgrade

suse:~# zypper list-patches
Loading repository data…
Reading installed packages…

Repository | Name | Version | Category | Status
————————————+———–+———+———-+——-
Updates for openSUSE 11.3 11.3-1.82 | lxsession | 2776 | security | needed

suse:~# zypper patch-check
Loading repository data…
Reading installed packages…
5 patches needed (1 security patch)

To look for a certain package with Zypper (equivalent of yum search packagename)

suse: ~# zypper search apache

To verify whether an RPM installed package dependecies are OK:

suse:~# zypper verify

The equivalent of Fedora yum update command in SuSE (SLES) are:

suse:~# zypper refresh

To force a complete refresh and rebuild of the database, including a forced download of raw metadata.

suse:~# zypper refresh -fdb

For people that are used to ncurses (midnight commander) like text interface you can also use yoast2 (text GUI) package manager:

suse:~# yoast2

update-linux-suse-server-with-yoast2-ncurses-package-text-gui-management-tool

If a package is messed you can always go back and use good old RPM (Redhat Package Manager) to solve it.

How to delete “Temporary Internet Files”/Content.IE5 with DEL and RD commands on Windows 7 / 8 folder contents – Clean Up Temporary files and folders to speed up and free disk space

Tuesday, February 3rd, 2015

7logo_clean-up-windows-commands-tips-and-tricks-how-to-clean-up-windows-pc-manually I
've been called urgently today by miss Jenia Pencheva who is the president of Christian Air Ticket Agency GoodFaithAir, her personal computer caused her quite a lot of headache, I've previously fixed it once and she was happy with that thus when she experienced problems she give me a call for remote IT support :).

She explahed her PC was unable to boot normally and in order to have some Windows she ended in Safe-Mode with Networking state. This problems caused her business losses as during PC in Safe mode the screen resolution even though with networking and she couldn't use the flight ticket ordering systems to purchase her customers new tickets. I've earlier installed TeamViewr on her PC so after Logging on the PC, I've immediately realized the Hard Disk was almost full (less than 1Giga free on C: Drive – where Windows install lived).

After a thorough investigation on which directory is occupying most of disk space (110GB) with a nice program called SpaceSniffer which is perfect for finding lost space on your hard disks, I've found System for ticket reservation Amadeus CRS (Computer Reservation System) was causing the disk full-full troubles.

spacesniff-visualize-disk-data-in-windows-nice-check-large-directories

I've found troubling directory was:

C:Users\goodfaithair\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.IE5

To solve it I first tried to Clean up Internet Explorer Cache (I've checked ticks Temporary Internet files, Cookies, History, Download History, Form Data, InPrivate Filtering Data).

Then I used Microsoft Windows embedded clean manager (cleanmgr.exe) to run disk clean up, however Desk Clean Up managed to clear up only about 1Giga and on the computer HDD which is 150Gb still on Windows installation drive C: only 1.5GB were free.
diskcleanup-ms-windows-7-8-screenshot-free-disk-space-tool
Besides that the system was having a second trouble as there were some failed updates (Computer was not shutdown properly but shutdown during Windows Update) and this was making the machine to enter Safe-Mode, I was fixing the system over TeamViewer session so after restart I had no way to see if Windows boots Normal or Safe-Mode after restart, thus to find out whether Windows was in Safe-Mode after another restart I've used below PowerShell one-liner script:

check-whether-windows-is-working-in-safe-mode-gwmi-powershell-screenshot

PS C:> gwmi win32_computersystem | select BootupState

BootupState
———–
Fail-safe with network boot

Note that possible return results from above command are:

Normal boot
Fail-safe boot
Fail-safe with network boot

I've been struggling for a while (had to restart it multiple times) until finally I managed to make it boot in normal mode. Because PC was failing to apply some Windows Update, thus dropping by in Safe-Mode each time. To solve that I had to go and Delete two of the last Applied updates (KB2979xxxx files).

Control Panel -> Program and Features -> View Installed Updates

MS-Windows-7-8-9-uninstall-updates-Patches-Control_Panel_screenshot_fix_unbootable_problems-because-updates
I've restarted and since I couldn't see the screen on Windows boot-time, I don't know what really happened but the PC booted again in Safe-Mode, and I thought the classical way to fix PC booting in Safe-Mode with SFC command will help:

C:> sfc /scannow

but for my surprise this helped not as the system continuously booted in Safe-Mode, to fix the Windows PC always booting to Safe-Mode, I had to change it running msconfig and unticking Safe Mode field

C:> msconfig

windows-always-booting-to-safe-mode-fix-howto-services-msc-screenshot

Then I tried to delete Temporary Internet Files with below DEL cmd line

C:> del "C\:Users\MyName\AppData\Local\Microsoft\Windows\Temporary Internet Files*.*"

To finally succeeding in manually delete huge Temporary Internet FilesContent.IE5 folder, I had to use good old RD (Remove Directory) command.

C:> RD "C:Users\username\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.IE5" /Q /S

I used also following dels command to delete other common locations where Windows stores temporary files

For those who like to batch DeletingTemporary Internet Files and most common Temp locations to be cleaned on Windows boot I recommend you schedule a start of (clean-temporary-internet-files-content_ie5_folder.bat) on every PC boot.

To Clean-up other common Temporary file locations that could take you disk space the command line way run in new Administarator privileged command prompt:

cls
cleanmgr /sageset:99
del /F /S /Q "%systemroot%temp*.*"
del /F /S /Q "%systemroot%Prefetch*.*"
del /F /S /Q "C:Documents and SettingsDefault UserLocal SettingsTemporary Internet FilesContent.IE5*.*"
del /F /S /Q "C:Documents and SettingsDefault UserLocal SettingsTemp*.*"
del /F /S /Q "C:Documents and SettingsDefault UserLocal SettingsHistory*.*"

del /F /S /Q "C:Documents and Settings%UserName%Local SettingsTemporary Internet FilesContent.IE5*.*"
del /F /S /Q "C:Documents and Settings%UserName%Local SettingsTemp*.*"
del /F /S /Q "C:Documents and Settings%UserName%Local SettingsHistory*.*"

del /F /S /Q "C:Documents and Settings%UserName%Local SettingsApplication DataTemp*.*"
del /F /S /Q "C:Documents and Settings%UserName%Local SettingsApplication DataTemporary Internet FilesContent.IE5

del /F /S /Q "C:AppDataLocalMicrosoftWindowsHistory*. *"
del /F /S /Q "C:AppDataLocalMicrosoftWindowsTemporary Internet FilesContent.IE5*.*"
del /F /S /Q "C:AppDataLocalMicrosoftWindowsTemporary Internet FilesLowContent.IE5*.*"
del /F /S /Q "C:AppDataLocalMicrosoftWindowsTemporary Internet FilesTemporary Internet FilesContent.IE5*.*"
del /F /S /Q "C:AppDataLocalMicrosoftWindowsTemporary Internet FilesTemporary Internet FilesLowContent.IE5*.*"

del /F /S /Q "C:Users%UserName%AppDataLocalTemp*.*"
del /F /S /Q "C:Temp*.*"
del /F /S /Q "C:Users%UserName%AppDataLocalMicrosoftW indo wsTemporary Internet FilesLowContent.IE5*.*
del /F /S /Q "C:Users%UserName%AppDataLocalMicrosoftW indo wsHistory*.*

::Rem: No need to duplicate the following section for each registered User
del /F /S /Q "%homepath%Cookies*.*"
del /F /S /Q "%homepath%recent*.*"
del /F /S /Q "%homepath%Local Settingscookies*.*"

del /F /S /Q "%homepath%Local SettingsHistory*.*"
del /F /S /Q "%homepath%Local SettingsTemp*.*"
del /F /S /Q "%homepath%Local SettingsTemporary Internet FilesContent.IE5*.*"

cleanmgr /sagerun:99

Note that in some cases running above commands might left you loose some sensitive data and in case where Internet is slow cleaning temporary files, might have impact on surfing also you will loose your history so be sure you know what you're doing as you might loose sensitive data.

Finally I've run MalwareBytes to clean up the PC slowness caused by Spyware and other left Malware I've run MalwareBytes, RogueKiller, AdwCleaner, RKill, TDSSKiller in order and I found and removed few Malwares as well.

That's all, hope you learned something new. Enjoy!
