Debian 9 Offline Installation Bug

I had to install a Debian 9.3 without having access to the internet, so I downloaded the full size offline install DVD from https://cdimage.debian.org/debian-cd/current/amd64/iso-dvd. As usual, I inserted the first DVD into the DVD Drive, started the install and everything worked fine - except for the moment where it didn't ;): I needed to switch DVDs for some software - and directly afterwards, Debian came to the "Install Grub" step - and asked politly to insert DVD 1 again - which I tried to do - but could not:

For some reason, the Debian GUI Installer had locked the DVD Drive and I could not remove the DVD - could not open it. I then used the Emergency Eject, inserted DVD 1 and closed the Drive again with very mild force.

However, the Installer did not recognize the new DVD and said, that I needed to insert a DVD. Well...

To cope with that problem, just CTRL+ALT+F1 switch to a different Terminal, enter mount /dev/cdrom /cdrom and switch back to the Installer Terminal with CTRL+ALT+F7 (I think it was ;)) - and hit "Continue" - and from that moment on, it worked again and the installation ended successful after the GRUB installation.

 

[RaspPi] Faintly glowing steady green LED on Raspberry Pi

[RaspPi] Faintly glowing steady green LED on Raspberry Pi

I got some serious issues with one of my Raspberry Pi, Modell B Rev. 2.0.
With an recent image, the Raspberry Pi refused to boot, but did only light up the red ACT LED as well as an really faintly glowing steady green PWR LED.
After my shop of trust sadly declined to help me with that issue, I tried to come up with every possible fix possible.

So, what can it be?
- Powersupply not beefy enough
- Micro USB Cable damaged
- Image was damaged during download / extract
- SD Card is not correctly flashed
- SD Card is damaged
- Wrong SD Card Type or RPi does not like it
- High Power drawing devices attached to USB Port
- SD Card Slot on the RPi is damaged / no contact

In my case, the solution was quite easy:
The SD Card did not connect correctly to the SD Card Reader in the RPi.
I just needed to rebend the legs of the SD Card Slot on the RPi, after that, it just worked perfectly again.

repair_rpi_sdcard_reader

The faintly glowing green LED says that the bootcode.bin could not be loaded, the first file that is pulled from the SD Card.
So it is a good hint for everything what could have gone wrong.

Other than that, a lot of good hints are shown on: http://elinux.org/R-Pi_Troubleshooting

[Samba] Windows Client can't access Unix Samba Share KB2536276

On 16.06.2011 Microsoft fixed an Security Issue with Samba which ended in Windows Users beeing unable to access Unix Samba Shares by using Plain Text Authentication.
By removing Security Update KB2536276 and rebooting you can enable your client again - or you patch your samba server, which is the real source of error - Microsoft did just fix an flaw.

[ESXi4.1U1] vCenter Server Startup Problems

I got the vmware virtualcenter server error 1000 odbc error on bootup of my Windows Server 2003 (64bit) which did serve my vCenter Server.
In fact this did mean in my case: The MSSQL Server didn't boot / or too slow, so that vCenter Server came up - couldn't access the DB and shutdown - "great!".
Luckily, there is an solution, pointed to by this ( http://communities.vmware.com/message/1247357 ) and this Website ( http://blogs.egroup-us.com/?p=1821 )

In the end I solved my problem following:
cmdline:
sc config vpxd depend= rpcSs/lanmanworkstation/MSSQL$SQLEXP_VIM/ADAM_VMwareVCMSDS

With these new dependencies, vCenter should boot up on boot... at least it did that last time... ^^'.
