PHP 5.3 big changes!

Lots and lots of things are deprecated!  Probably a good idea to change the error reporting to something like:
error_reporting = E_ALL & ~E_NOTICE ~ E_DEPRECATED

magic_quotes_gpc,register_globals,safe mode seem to be deprecated

Short PHP tags are disabled by default:
short_open_tag = On

more to come I’m sure…….

MySQL reset lost root password

/etc/init.d/mysql.server stop
/usr/local/mysql/bin/safe_mysqld –user=mysql –skip-grant-tables –skip-networking &
mysql> UPDATE mysql.user SET Password=PASSWORD(‘MyNewPass’) WHERE User=’root';
mysql> exit
/etc/init.d/mysql.server restart

Probably a good idea to clear the MySQL history afterwards or pull in the update from a txt file and delete!

Appcmd IIS7 command line tool

Appcmd list sites
Appcmd list site “sitename” /config

Appcmd start/stop sites “Default Web Site”
(or whatever site you want to start)

Appcmd add sites /name:”Site 5” /id:12 /bindings: /physicalPath:C:\inetpub\site5

Backup IIS config:
appcmd add backup
appcmd list backup
appcmd restore backup

It has much much more functionality – appcmd /h

Save password for mapped network drive

When you map a network drive in Windows, with a non-domain user for example, Windows will save the username but not the password.  To persistently store the password, use the following from cmd:

net use x: \\server’\share /savecred /persistent:yes

Auto restart IIS when service unavailable

A bit crude but it works.  Make a schedule task for this batch file:

del testsql1.asp
C:\wget\wget.exe –timeout=30 –tries=1
find /C “SQLServer Test Code 1″ testscript.asp

Force group policy update

To manually force Group Policy to refresh under Windows 2000, you use the command

secedit /refreshpolicy

Microsoft has replaced this command in Windows 2003 and XP with this command:


Stop BackupExec failing on corrupt files

I expect there will be a flag for this in future versions, but for now regedit is needed:

HKEY_LOCAL_MACHINE\SOFTWARE\VERITAS\Backup Exec\Engine\Backup [For versions 9x and 10x]
HKEY_LOCAL_MACHINE\SOFTWARE\SYMANTEC\Backup Exec for Windows\Backup Exec\Engine\Backup [For versions  11x and 12x]

On the menu bar, select Edit | Add Value
In the Value name field, type in “Fail Jobs On Corrupt Files”
For the Data Type, select REG_DWORD (Figure 1)
When prompted for the Data, type in “0” (without the quotes)
Click OK

IIS File Upload Limit

By default IIS sets the upload filesize limit to a measly 200KB.  To edit this you need to enable direct metabase editing in IIS, then edit c:\windows\system32\inetsrv\Metabase.xml .  You need to modify the MaxRequestEntityAllowed which is in bytes.  Restart IIS.

BASH create random password

apg -MSNCL  -m8 -x11 -n10 -E\%\\\/\|\`\<\>\+\{\}\”\’


< /dev/urandom tr -dc A-Za-z0-9_$*?! | head -c10

Another useful implementation thanks to, a sample random password generator (put in your ~/.bashrc):
genpasswd() {
local l=$1
[ "$l" == "" ] && l=20
tr -dc A-Za-z0-9_ < /dev/urandom | head -c ${l} | xargs }

Run it:
genpasswd 16
