Setting keep alive for unix

We have to change the value shown by:
>cat /proc/sys/net/ipv4/tcp_keepalive_time

-usually is 7200

To change it:
- >sudo vi /etc/rc.local #to remain after boot
- echo "900" > /proc/sys/net/ipv4/tcp_keepalive_time #to modify
- >sudo /etc/rc.local #to have it

Other way:
- >sudo sysctl -w net.ipv4.tcp_keepalive_time=1800

Moving from Windows XP to Linux Ubuntu

It was easy because all you have to is to just copy a folder, usually from 'Documents and Settings\\Application Data', to your home directory /export/home/:
-email - Thunderbird - the profile folder
-text editor - Jedit - the .jedit folder
-DB client - Squirrel - .squirrel
-IM - pidgin - .purple

Automate Windows XP services management

When are problems and don't want to manually process all Windows XP services, the tool below can be used :

(thx to http://commandwindows.com/sc.htm )
services_automate.bat :

@echo off

set lp=%~dp0

cd %lp%
rem sc [command] [service name] ...
rem interesting is also the "config" command

echo "Starting setting of services to automatic"
for /F "delims= " %%i in (%lp%\services_names.txt) do (
echo "%%i"
sc start %%i
)
echo End
rem pause

(I got it from web, but can't find now the source to mention :( )
