svchost.exe high memory usage – wuauserv

In my experience, when wuauserv starts eating memory, the best thing to do is to wait until it finishes installing the updates and then reboot.

If you can’t or aren’t willing to reboot now, you can always reset wuauserv with the following BAT script (right click & run as administrator):

net stop wuauserv
net stop bits
rd /s /q %windir%\softwaredistribution
net start bits
net start wuauserv
wuauclt.exe /detectnow

Hope it helps.

Bypassing censorship by using obfsproxy and openVPN , SSH Tunnel | Container of Scribbles

Syrian ISPs are using sophisticated technologies to monitor and filter traffic. These boxes are DPI (Deep Packet Inspection) and what they do is sniff out every little packet flowing through them to find specific patterns and then they provide their administrator with the option to block traffic that matches these patterns. These boxes are very sophisticated and they don’t just filter traffic by src, dst or port, they filter traffic by the content the packets carry.

OpenSSH to OpenSSL

OpenSSH private keys are directly understable by OpenSSL. You can test for example:

openssl rsa -in ~/.ssh/id_rsa -text
openssl dsa -in ~/.ssh/id_dsa -text

So, you can directly use it to create a certification request:

openssl req -new -key ~/.ssh/id_dsa -out myid.csr

You can also use your ssh key to create a sef-signed certificate:

openssl x509 -req -days 3650 -in myid.csr -signkey ~/.ssh/id_rsa -out myid.crt

Notice I have not found how to manipulate ssh public key with OpenSSL
