DHCP-Snooping and Baramundi PXE

bug

Hey folks just a short notice for everyone who uses this combination on Procurve (Maybe this also applies to Cisco and / or Comware) switches. If you enable and configure DHCP-Snooping with trusted ports and authorized servers don’t forget to also authorize the Baramundi PXE Server…

I have no idea why this thing acts like a DHCP server (I’m not really a windows guy 😉 ) but after authorizing it as “DHCP Server” in the snooping, the PXE feature works again on all clients.

Back in da hood!

IcelandShort notice that im back home and things will go on normal now!
Will migrate the beta OS X links soon to the site header.

Btw. Iceland is one of the most interesting and definitely beautiful country i’ve ever seen! Going back to Iceland and Greeland soon 🙂

Using betas in stable Yosemite (10.10)

Apples-OS-X-YosemiteJust a short tip for everyone who needs access to betas without a developer account. The follow command brings back access to regular beta downloads via the AppStore!

 

Just replace the Catalog URL with:

sudo defaults write /Library/Preferences/com.apple.SoftwareUpdate CatalogURL https://swscan.apple.com/content/catalogs/others/index-10.10beta-10.10-10.9-mountainlion-lion-snowleopard-leopard.merged-1.sucatalog.gz

Have fun!

Synology TimeMachine and OS X 10.9

synoIf somebody ever wondered about the TimeMachine error message “This backup is already in use” or in german “Dieses Backup wird bereits verwendet”. I think the Synology has problems with PowerNap or some other suspend mode in OS X 10.9.x.

Normally the error is gone after you rebooted the Synology but would you really reboot your NAS every few days? No!

This trick assumes that you have full SSH root access to your NAS. If not please enable SSH on your Synology, you can use this guide to get it enabled.

After you enabled SSH please be sure that no other TimeMachine Backup is running and login to your NAS.

find /volume* -name com.apple.TimeMachine.Results.plist

If you know the full path to your TimeMachine folder, please replace the “/volume*” with this path, otherwise this can take some time, depending on your amount of files.

You should now know the full path to that file. Now it’s time to rename it! If your path is like “/volume1/timemachine/mbp.sparsebundle/com.apple.TimeMachine.Results.plist” You can rename it with:

mv /volume1/timemachine/mbp.sparsebundle/com.apple.TimeMachine.Results.plist \
/volume1/timemachine/mbp.sparsebundle/com.apple.TimeMachine.Results.plist.BAD

If you have multiple TimeMachine backups saved on your NAS, the directories are different! After you renamed the file, the backup should run fine again!

Edit: If this does not work for you, search for running processes on the Synology with the username of your TimeMachine User. Kill all of those processes and you should be fine.

Search for this PID (My user is “tm“, yours is very likely different):

ps | grep tm | grep -v root

Output should like this:

17465 tm 23380 S /usr/syno/sbin/afpd -g guest -c 256 -n pandora6 AFPServer -l default log_error

Now kill that process with the PID (Yours is different!):

kill 17465

Windows 7 ISO with VirtIO drivers

If somebody needs it, i’ve made a ISO image of Windows 7 with SP1 and VirtIO drivers integrated. Some Cloud hosters needs the VirtIO drivers for the storage. You can install Windows 7 on Vultr with this image. Keep in mind this is a german language ISO, but you can install language packs after the installation.

Big Beta news from Apple!

Bildschirmfoto 2014-04-23 um 07.26.31Thats surprising… if you not already read it on the web, Apple opened the Beta Seeds to the public! At least for Mavericks it’s now possible to get the betas a legal way direct from Apple without any Developer restrictions! Never thought i’d live to see this day!

More info here: https://appleseed.apple.com/sp/betaprogram

 

Side note: Please install the latest OS X security update 2014-002 as soon as possible, some serious bugs are fixed!

HP iMC Software on CentOS 6

Just for everyone who have the same problems with installing that Java software on CentOS6. The database config is really strange… if the Deploy fails for you, just open your desired MySQL Database manager, or do it directly on the cli. Open the user management, or just the table, change the hostfield  from “%” to “localhost” of each iMC added user. In my case this was:

imc_aclm
imc_config
imc_icc
imc_monitor
imc_perf
imc_syslog
imc_vlan
imc_vnm

“iMC deploy” adds all users with “%” but later iMC trys to connect with e.g. imc_config@localhost and gets a Access denied from mysql. Thats the reason why all deploy jobs fails on CentOS 6 and iMC 5.2 :/ If you need the password, which is a randon generated one, from each user you can get it with:

/opt/iMC/deploy/pwdmgr.sh -query 127.0.0.1 config_db <username>

MacBook Pro 11,2 and AirPort Extreme problems… (Update 1)

802-11ac-wi-fi

Folks, a new day a Apple Wifi problem… Did anyone out there also notice the horrible 5GHZ AC connection from the latest MacBook Pro and the latest AirPort Extreme? I have pings between 2ms to 1000ms, paket loss and very very low transfer speeds of under 10Mbit/s. The funny thing is, the Signal/Noise ratio is perfect, the signal is excelent and even the Apple indicates a full speed connection of “1300” Mbit/s….

I noticed, if there is a lot of load on the Wifi the ping answers are way better (Down to 5ms and stable) as with no load and only background noise… the first thing i said to myself, hmm maybe engery saving but there is not option to change anything in this direction. There is no difference between WPA/WPA2/WPA2 Enterprise, always the same behavior. If i change the Wifi channel, the problem is gone for some time, but not for long. If my MBPr goes to sleep and woke up, the same strange thing. So my question, is anybody out there with the same or similar problems?

Edit: Temporary fix is to disable Power Nap! So wifi also sleeps and gets powered up on wake up. This solves my problem, well new OS, new Book, new Airport, i expected something like this :/

Edit 2: The latest AirPort Extreme Firmware update solved almost all issues.
