I know iOS is a super fast and optimized operating system but still there are some services that start but are unuseful for us and consume memory that can be used in other ways.
So in order to disable this services you must have a jailbroken iDevice with OpenSSH installed (you can install from Cydia).
How connect to your device (after you connected to an wireless network) using Putty or any other ssh client (Mac users can connect from terminal). The default password for OpenSSH after fresh install is: alpine
Now copy line, one by one in order to disable the services.

Reboot your iDevice. Now the startup speed should be improved. Also memory usage on fresh reboot is lower.
Tried these optimizations on iPhone 3GS and iPad 3G.
For those people who get error on launching greenp0ison on OSX 10.5.8.
Dyld Error Message:
Library not loaded: /usr/lib/libcurl.4.dylib
Referenced from: /Users/username/Downloads/greenpois0n-5.app/Contents/MacOS/greenpois0n
Reason: Incompatible library version: greenpois0n requires version 6.0.0 or later, but libcurl.4.dylib provides version 4.0.0
Here is a fast fix:
Download libcurl.4.dylib
unzip the archive
- open terminal
- sudo su
- copy the file to /usr/lib overwriting the current one then.
- then use: cd /usr/lib
- Use command: chown root:wheel libcurl.4.dylib
- Use command: chmod 755 libcurl.4.dylib
start greenp0ison
I recently had and intervention on a company that reported a blue screen of death on one of their servers.
Error was:
0x0000007B
INACCESSIBLE_BOOT_DEVICE
The server had the role of SQL Server for one of their ERP applications. Specs of so called “server” were:
Intel Core Duo CPU
2 GB RAM
2 x S-ATA HDD (RAID1)
In fact this was a normal PC, with the function of a server. The bad idea was to make on this system PC a RAID1 using that motherboard and no additional controller.
Going to BIOS I found out that settings were reset by the motherboard battery malfunction and the on-board mode for HDD controller was set to S-ATA mode and not on RAID.
After fixing the problem, their server booted flawless into the windows.
I know this seems a silly and simple idea, but hope it helps people who encounter this type or error on their systems, even if they have server or pc systems.
Acum cateva zile s-a terminat IT Congress editia II. Eu am fost unul dintre baietii din staff-ul tehnic care am prezentat tehnologii VMWare, Wyse, 10zig ma refer aici cu accent deosebit pe partea de VDI (Virtual Desktop Infrastructure).
Lume a fost si destule intrebari de asemenea, totusi timpul alocat subiectelor din pacate, a fost foarte scurt, nu prea am avut timp sa explic si sa raspund la intrebari asa cum mi-am dorit si cum mi-am planificat de la inceput.
Despre ce am discutat poate va intrebati cei care nu ati fost?
- VMWare View 4.0 (integrare AD, permisii / user, tipuri de grupuri de masini, linked clone)
- Wyse (P20 Thin Client cu PCoIP, demo multimedia, integrare cu view manager)
- Wyse (V10L Thin Client cu RDP si TCP, usb redirect, sunet bi-directional integrare cu view manager)
- 10zig (cu RDP 7, sunet bi-directional cand te conectezi pe Windows Server 2008 R2)
Atasez cateva poze de la IT Congress 2010.
1) Pregatiri
2) De sus in jos (Cisco Nexus + NetApp Storage)
2) De la stanga la dreapata (V10L, 10zig, P20 cu PCoIP)
3) Stand VMWare cu Thin Clients, fiecare ruland un trailer pe RDP si PCoIP
5) Una din prezentarile VDI si lumea prezenta.
(am sa revin cu mai multe poze & video, cele postate sunt facute de mine cu telefonul si nu am avut timp de prea multe)
