I just read this article from Lifehacker and I found these shortcut really great! I never knew that there are shortcuts for these kind of everyday tasks. I love these shortcuts.

• Win+R: shows Run dialog
• Win+D: toggles Show Desktop
• Win+E: starts Windows Explorer
• Win+L: locks computer

If you use Firefox , below shortcut are useful too.

• Ctrl + L : brings focus to the location bar.
• Ctrl + K : brings focus to the search bar.

LifeHacker: Make Windows More Productive Without Installing a Thing

So I have searched many Google pages and found this PuTTY Connection Manager which I explained details in my previous post. It is a very good software.

But somehow I wanted the auto login function without the extra programs. I wanted it to be done directly with PuTTY, not within the frame of PuTTY Connection Manager.

And I found this software called AutoHotKey (http://www.autohotkey.com/) which can automate keyboard and mouse actions. But I gave up to use it at that time because I was too lazy to read all the instructions and to come up with a script for the auto login.

But yesterday, I decided to take a look again and this time I successfully created the Auto Login script! To tell you the truth, it was not easy but it is worth it. I am proud of myself

So here is the script.

; You need to define the full path where the putty.exe exists . 'putty_profile' should be existing profile name.
v_program=%A_ProgramFiles%\PuTTY\putty.exe -load putty_profile
v_userid=youruserid
v_passwd=yourpasswd
; msec to wait before sending userid
v_wait_userid=1000
; msec to wait before sending password
v_wait_passwd=500
 
;-------------------------------------------------
; To make modifier keys to work properly (such as Shift)
SetKeyDelay, 0, 10
 
run, %v_program% , , , newpid
 
;you need to wait a little for the window to initialize
;sleep, 100
winwait, ahk_pid %newpid%
 
;wait for the login prompt to appear
sleep, %v_wait_userid%
ControlSend, , %v_userid%{enter}, ahk_pid %newpid%
 
sleep, %v_wait_passwd%
ControlSend, , %v_passwd%{enter}, ahk_pid %newpid%
 
;create unique title so you won't be lost 
WinGetTitle, v_title, ahk_pid %newpid%
v_newtitle=%v_title% - %newpid%
WinSetTitle, ahk_pid %newpid%,,%v_newtitle%

If you want to try this yourself, you will need to change some information.

1. Install AutoHotKey software.
2. Create any file name with extension .ahk. For example ’ssh.ahk’ would be fine.
3. Copy & paste above code into the file. But need to change the values.
   v_program: PuTTY location with the -load option and connection profile name
   v_userid: userid
   v_passwd: passwd
   v_wait_userid : msec to wait before sending userid
   v_wait_passwd : msec to wait before sending passwd
4. Save it and double click on the file to execute it. And watch the PuTTY logging in the server automagically!

In fact, you can easily add additional commands at the end of the script to execute further commands.

Below is an example.

;maybe you want to wait some seconds while initial welcome screen appears. Let's say 2 seconds.
sleep, 2000 
 
;cd upload
ControlSend,,cd upload{enter} , ahk_pid %newpid%
 
;You can send the folder list to your email account.
ControlSend,,ls|mail -s "Daily File Listing for Upload" your@emailaccount.com{enter}, ahk_pid %newpid%

Note that there is a little issue that the password is saved as plain text. But I can live with it for now.

Here is my script in action.

You can prevent this situation by using HiddenStor and HideFiles options if you are using proftpd ftp server.

<Global>
  AllowOverwrite                yes
  #slee:using .in.$filename convention and block other connection to download
  #must work with  HideFiles
  HiddenStor on
 
  <Limit ALL SITE_CHMOD>
    AllowAll
  </Limit>
</Global>
 
<Directory /*>
  #HideFiles (\.conf|passwd)$
  HideFiles (\.in.*)$

By defining the correct options, you can effectively block the unfinished uploading files to be shown in the directory listing.

first install source rpm package using rpm command

goto /usr/src/SPECS folder

edit httpd.spec

for example you may want to edit configure part of the httpd.spec file

and then

You can create binary rpm package (redhat 8 & up)

rpmbuild -bb httpd.spec

compiled files will be written in /usr/src/BUILD folder

Then you can use rpm -ivh command to install it.

The main reason was to implement GD2 functions in PHP.
And to install the softwares using rpms as much as possible.

I know. It was a pain.

Before you’re doing anything copy existing config files

$>cp -r /etc/httpd /etc/httpd.backup
$>cp  /etc/php.ini /etc/php.ini.backup
$>cp -r /etc/php.d /etc/php.d.backup

Also , find a fast redhat 9 rpm download site.
You will need to download & install bunch of rpms if you haven’t.

First I downloaded httpd-2.0.54.tar.gz from apache.org website.
And I realized that there is a .spec file. It means that you can use rpmbuild command to compile & install it.

so…

I unzipped & untarred httpd-2.0.54.tar.gz

Also, had to copy httpd-2.0.54.tar.gz in /usr/src/redhat/SOURCES

Then I chdir into the untarred directory & ran

$> rpmbuild -bb httpd.spec

Then it prompted me lots of dependent rpm packages.
Some of them I was lucky that I found rpm packages from rpmfind.net
But, I had to compile few of the packages manually.

Anyway, I used –nodeps option when running found rpm packages.
It worked anyway.

by running -e option you need to uninstall previous default httpd version

$> rpm -e httpd-2.0.40-21
$> rpm -e httpd-devel-2.0.40-21
$> rpm -e httpd-manual-2.0.40-21

and chdir into /usr/src/redhat/RPMS/i386

You will see 3 rpms. You need to install at least 2 rpms.

$> rpm -Uvh httpd-2.0.54-1.i386.rpm
$> rpm -Uvh httpd-devel-2.0.54-1.i386.rpm

For the php, I downloaded the lastest PHP 4 package. I wanted PHP4 since I felt like PHP5 might cause more problem during the installation.

I’ve got the configure lines by creating a test php page and inserted phpinfo() function. When you visit this test php page with the browser, I will be able to find the configure command used to compile the current PHP .

I have used this command to configure my new 4.4.0 package.

But during the steps the options reduced down to below

'./configure' '--host=i386-redhat-linux' '--build=i386-redhat-linux' \
	'--target=i386-redhat-linux-gnu' '--program-prefix=' '--prefix=/usr' \
	'--exec-prefix=/usr' '--bindir=/usr/bin' '--sbindir=/usr/sbin' \
	'--sysconfdir=/etc' '--datadir=/usr/share' '--includedir=/usr/include' \
	'--libdir=/usr/lib' '--libexecdir=/usr/libexec' '--localstatedir=/var' \
	'--sharedstatedir=/usr/com' '--mandir=/usr/share/man' \
	'--infodir=/usr/share/info' '--cache-file=../config.cache' \
	'--with-config-file-path=/etc' '--with-config-file-scan-dir=/etc/php.d'\
	'--enable-force-cgi-redirect' '--disable-debug' '--enable-pic' \
	'--disable-rpath' '--enable-inline-optimization' '--with-bz2' \
	'--with-curl' '--with-dom=/usr' '--with-exec-dir=/usr/bin' \
	'--with-freetype-dir=/usr' '--with-png-dir=/usr' '--with-gd' \ 
	'--enable-gd-native-ttf' '--with-ttf' '--with-gdbm' \
	'--with-gettext' '--with-ncurses' '--with-gmp' \
	'--with-iconv' '--with-jpeg-dir=/usr' '--with-openssl' '--with-png' \
	'--with-pspell' '--with-regex=system' '--with-xml' \
	'--with-expat-dir=/usr' '--with-zlib' '--with-layout=GNU' \
	'--enable-bcmath' '--enable-exif' '--enable-ftp' \
	'--enable-magic-quotes' '--enable-safe-mode' \
	'--enable-sockets' '--enable-sysvsem' '--enable-sysvshm' \
	'--enable-discard-path' '--enable-track-vars' \
	'--enable-trans-sid' '--enable-yp' '--enable-wddx' \
	'--without-oci8' '--with-pear=/usr/share/pear' \
	'--with-imap=shared' '--with-imap-ssl' '--with-kerberos=/usr/kerberos' \
	'--with-ldap=shared' '--with-mysql=shared,/usr' '--with-unixODBC=shared' \
	'--enable-memory-limit' '--enable-bcmath' '--enable-shmop' \
	'--enable-versioning' '--enable-calendar' '--enable-dbx' \
	'--enable-dio' '--enable-mcal' '--with-apxs2=/usr/sbin/apxs' \
	'--with-mhash'

I needed those ‘–with-mhash’ for some personal reason.

then I ran

$>make
$>make install

Now chdir into modules directory & copy all .so files into /usr/lib/php4.

$>cp *.so /usr/lib/php4

You need to manually copy the php.ini-dist into the /etc directory.
Also you might want to modify the php.ini comparing with the backedup php.ini file if you have customized the previous version php.ini file.

Especially make sure you insert the

extension_dir = "/usr/lib/php4"

in the new php.ini.
