SSH Versus SSL (Difference)


Hi everyone,

I googled and found out some differences.

SSH protocol is mainly used for shell based solutions and won’t be used to protect web browsing sessions and other application services 
SSL protocol is mainly used for secure http sessions (HTTPS). Now a days, all browsers are coming with built in SSL Protocol support with CA(Certification Authority) root certificates.  We no need to configure to use the SSL. No extra client software needed to use SSL.

SSH protocol is used to remotely login to remote network system/server and execute commands.

SSL protocol is used to send the data/files securely to a remote and/or network system.

Windows 7 64-bit Printing Issue, XPS to OneNote Convertion as Solution

Hi everyone,
Today I have come across with an issue while taking print. In 32-bit Windows Os, We can have adobe reader in printer to save the print file in .pdf format (or) OneNote to store the print content as page(s) by the option "Send to OneNote".

In 64-bit OS, Only the XPS viewer is defaultly added in the Printers list. We are unable to add either Adobe PDF or Send to OneNote.

Solution:
1) Print the file in .xps format then convert into pdf or OneNote for viewing and editing.
2) Convertion of XPS to PDF, I have already explained in one of my previous post.
3) Converting XPS to OneNote can be done in the following manner.
4) Download the file XPS2OneNoteSetup.msi
5) Install the file xps2onenotesetup.msi.
6) Print the file and save as xps file.
7) Drag and Drop the xps file to the folder "XPS Print to OneNote Drop Folder", which is on Desktop.
8) We can see the following window to select different option of print to onenote
9) Select the relevant section and store the file as per your choice by selecting "Print to single page/multiple pages"
10) Then you can do edit, copy, paste and etc operations to the file.

Porteus Linux : Make USB Pen Drive Bootable Sctipt Execution Problem With Solution

Hi all,

Today I have come across one interesting problem with the Porteus Linux.

I formatted my USB drive with ext2 filesystem.

I was trying to make USB drive bootable by executing lin_start_here.sh, after installing the Porteus.
It was displaying the md5 checksum computation error. But I am sure that, md5 checksum is correct, Because I have already executed the porteus/chkbase.sh separately

So, I have reviewed the code of lin_start_here.sh and I come to know the it is executing the boot/syslinus/bootextlinux.sh. I also reviewed the bootextlinux.sh and I come to know that, it is trying to execute the following command.

pushd ../porteus --Change to the porteus directory and maintain the stack of dirs
sh chkbase.sh -- Results error
popd --Pops the porteus directory from stack and comes to its previous directory


Please give write file permission to boot/syslinus/bootextlinux.sh and then


Please modify it as following
pushd ../porteus
./chkbase.sh
popd


Now run the following commands
cd boot
./lin_start_here.sh

I thought of blocking all my system ports and allow only http(s) ports. Because I am not going to use any others ports except http(s).

With IPkungfu tool, it is possible to block all the ports and allow the necessary ports.

Installing IPkungfu
# apt-get install ipkungfu

Configure IPkungfu
1) /etc/ipkungfu/ipkungfu.conf  //Change the firewall settings
2) /etc/ipkungfu/services.conf  //Change the Port settings
    Syntax: ServiceName: ServicePort:Protocol[:ACCEPT]
    Example:
       http:80:tcp:ACCEPT  //Allow Port
       ftp:21:tcp  //Block Port

Test IPkungfu
# ipkungfu --test

Decode MD5 Hash Value *

Hi everyone,

One of my friend asked me about decoding the hash value. When I searched in internet, I found one hash decrypter. But it is having very limited decryption technique like only chars in plain text.

For online MD5 Encoder:
http://7thspace.com/webmaster_tools/online_md5_encoder.html

Any how, you can try these decoders
http://www.tmto.org/pages/passwordtools/hashcracker/
http://md5.noisette.ch/

Anyway, once you insert some new string hash value in database, then it will display. Else if you put your new string with special characters and all. Then it won't work.

Happy Decoding !!!
