Excel 2007 No Right Click Menu - AGAIN!!

If a user doesn't have the option menu on right click in Excel, do the following:

1. Close All Open Excel.
2. Go to C:\Documents and Settings\[userID]\Application Data\Microsoft\Excel
3. Delete the XLB file.
4. Open Excel (the XLB file will be recreated - like the normal.dot)

This one really works permanently

Iptables block facebook

There are many “solutions” for blocking your company employees accessing Yahoo Messenger, hi5, Facebook or any other distracting services, but none of them is working properly.



So here is a perfect solution:


What you need:


- linux router for your network
- iptables firewall at least v1.3.7


Here are the rules:
Deny Yahoo Messenger packets:


iptables -I FORWARD -m string --string 'YMSG' --algo bm -j DROP
iptables -I FORWARD -m string --string 'messenger' --algo bm -j DROP
iptables -I FORWARD -m string --string 'meebo' --algo bm -j DROP
iptables -I FORWARD -m string --string 'buddy' --algo bm -j DROP
iptables -I FORWARD -m string --string 'webmessenger' --algo bm -j DROP
iptables -I FORWARD -m string --string 'web-messenger' --algo bm -j DROP


Deny facebook traffic rule:


iptables -I FORWARD -m string --string 'facebook' --algo bm -j DROP


Deny hi5 traffic rule:


iptables -I FORWARD -m string --string 'hi5' --algo bm -j DROP

and so on… you can modify these rules to fit your needs, you just need to edit the –string parameter


--string ''


Using this solution to filter specified traffic you don’t have to worry about port, protocol, application , source or destination.


Hope it helps someone.

Block Internet Messenger With Iptables

normally we will use port filtering with iptables to block the internal user from accessing unwanted application or website but here the tips for you to do it :


If you’re a network administrator and you’re using Linux on your servers, you can stop the rest of the users from using IM applications by blocking their access to the most-used IM protocols:




ICQ and AOL:


# iptables -A FORWARD –dport 5190 -j DROP
# iptables -A FORWARD -d login.oscar.aol.com -j DROP


MSN:


# iptables -A FORWARD -p TCP –dport 1863 -j DROP
# iptables -A FORWARD -d 64.4.13.0/24 -j DROP


Yahoo Messenger:


# iptables -A FORWARD -p TCP –dport 5000:5010 -j REJECT
# iptables -A FORWARD -d cs.yahoo.com -j REJECT
# iptables -A FORWARD -b scsa.yahoo.com -j REJECT

# bal_local Load-balance internet connection over two local links

# Version: 1.0.0 - Fri, Sep 26, 2008

# Author: Niels Horn

# Set devices:
DEV1=${1-eth0} # default eth0
DEV2=${2-ppp0} # default ppp0


# Get IP addresses of our devices:
ip1=`ifconfig $DEV1 | grep inet | awk '{ print $2 }' | awk -F: '{ print $2 }'`
ip2=`ifconfig $DEV2 | grep inet | awk '{ print $2 }' | awk -F: '{ print $2 }'`


# Get default gateway for our devices:
gw1=`route -n | grep $DEV1 | grep '^0.0.0.0' | awk '{ print $2 }'`
gw2=`route -n | grep $DEV2 | grep '^0.0.0.0' | awk '{ print $2 }'`


echo "$DEV1: IP=$ip1 GW=$gw1"
echo "$DEV2: IP=$ip2 GW=$gw2"


### Definition of routes ###


# Check if tables exists, if not -> create them:
if [ -z "`cat /etc/iproute2/rt_tables | grep '^251'`" ] ; then
echo "251 rt_dev1" >> /etc/iproute2/rt_tables
fi
if [ -z "`cat /etc/iproute2/rt_tables | grep '^252'`" ] ; then
echo "252 rt_dev2" >> /etc/iproute2/rt_tables
fi


# Define routing tables:
ip route add default via $gw1 table rt_dev1
ip route add default via $gw2 table rt_dev2


# Create rules:
ip rule add from $ip1 table rt_dev1
ip rule add from $ip2 table rt_dev2


# If we already have a 'nexthop' route, delete it:
if [ ! -z "`ip route show table main | grep 'nexthop'`" ] ; then
ip route del default scope global
fi


# Balance links based on routes:
ip route add default scope global nexthop via $gw1 dev $DEV1 weight 1 nexthop via $gw2 dev $DEV2 weight 1


# Flush cache table:
ip route flush cache


# All done..


chmod +x the script and call it with ./yourscript eth0 ppp0 after connected to the internet. change accordingly to fit your need such as adding more ISP
