Creating copy of Virtual Box instance

February 28th, 2010

I had faced  problems in creating a same copy  of the VB system .
I tried to do by creating a copy of the hard disk and adding it to the environment. This will not work since the copied will has the same hard disk identification of  the source .
I was able to solve this issue using the command “VBoxManage clonevdi ”
you need to give the full path  for the files eg

VBoxManage clonevdi  /home/itsupport/.VirtualBox/HardDisks/PBX1.vdi /home/itsupport/.VirtualBox/HardDisks/PBX2.vdi

, otherwise it will throw an error

Blocking downloading of files using SQUID

We can use ACL to block the download
Step 1
add following lines in to the ACL  ection
acl blockfiles urlpath_regex “/etc/squid/blocks.files.acl”

and to display cusotm error message when users try to download
add

# Deny all blocked extension
deny_info ERR_BLOCKED_FILES blockfiles
http_access deny blockfiles

Step 2
After editing and closing the file . Create custom error message file called “ERR_BLOCKED_FILES” in /etc/squid/error/ directory or /usr/share/squid/errors/English directory.

<HTML>
<HEAD>
<TITLE>ERROR: Blocked file content</TITLE>
</HEAD>
<BODY>
<H1>File is blocked due to new IT policy</H1>
<p>Downloading files causes network trafic</p>

Step 3
nano /etc/squid/blocks.files.acl
add the follwing text

\.[Ee][Xx][Ee]$
\.[Aa][Vv][Ii]$
\.[Mm][Pp][Gg]$
\.[Mm][Pp][Ee][Gg]$
\.[Mm][Pp]3$

A restart of squid will do the trick

February 24th, 2010

Naming method looks like

  • “CCC X S O E/B “

  • S => S is the no of extensions or FXS lines
  • O => is the no of trunk lines

My selected card is TDM-808EF
