If you are on this page you probably have an HTC HD2 phone and looking to install Skype on it. There are a lot of forums about how compatible is Skype with windows 6.5 and most of them say that it was.. but Skype stopped supporting windows 6.5. Yet seems that Skype works fine on my HTC HD2 Windows 6.5 from T-mobile.  The installation was simple just unzip and upload the CAB file.SkypeWM_v3.0.0.256

After installing it took some time to login. I turned on Wifi and it worked. First it asked me to use headsets. I did not… So I could not hear the other side but they could hear me.

Plugged in the Headset and it worked. I also turned off the Wifi and still worked.  I am glad it works fine was at the point of installing Android on my HTC HD2. Lets hope now that Microsoft bought Skype it will run on MS and will be supported. Still dont understand why Skype is not supporting it anymore …

Only thing you should be careful with is your Data plan as the traffic may eat up your 200mb limit if you are not on a bigger plan

When I first got my new laptop I thought that 50GB will be enough for program files on the C partition and created a G partition for storage.

Few months later the 50GB were not enough and needed to extend it. But when I tried to do that the Extend option was GRAYED OUT.

Extending partitions can be done by >START MENU > Over “MY COMPUTER” Right click> Manage

The reason why I could not extend it is because the new Part. G was on the right of C so if you want to extend your C drive you need to:

1-Backup  all your “storage” partion on an external drive. Or create a new partition if you have enough space example partition F and move the content.

2-Delete your old storage partition G

3-Then you will see the extend option not grayed out anymore… So you can extend C again.



Note If you enable this feature, the shutdown time may be increased.

Sometimes the OLD DNS entry will be cached and you will need to either flush the DNS cache to get rid of it, or wait up to 24 hours for it to be dropped from the cache automatically.

To do this in windows click on Start=>Run

then type: cmd

in the black window type:

ipconfig /flushdns
Press enter.

If you get an error saying:


1. Click Start or Windows logo at the bottom left corner of the screen
 2. Click All Programs
 3. Click Accessories
 4. RIGHT-click on Command Prompt
 5. Select Run As Administrator
 6. In the command window type the following and then hit enter:  ipconfig /flushdns
 7. You will see the following confirmation:



Windows IP Configuration
 Successfully flushed the DNS Resolver Cache.




If you get an error msg saying:
" Windows IP Configuration
Could not flush the DNS Resolver Cache: Function failed during execution."

Go to: Start>> Control Panel >> Administrative Tools >> Services (Open services)



in the list find: " DNS Client" right click >> Properties >> Change "Start up Type" to automatic >> Click Start

Now you should be able to flush your dns.



After done make sure you put back DNS Client to disabled.

An easy way of migrating the databases especially when it is a big database and it size is over what you have in PhpMyAdmin setup:
Login to the new server with ssh and type:
mysqldump -h oldhost -u oldusername -poldpassword olddbname | mysql -h newhost -u newusername -pnewpassword newdbname

Note: if this did not work check your passwords or check if your new server is white listed (remote mysql access) on the old server.

Below is a list of common SSH commands that can be very useful I will be updating this as I suffer through my hosting (Article provided by WebHostGear.com):

Common SSH Commands or Linux Shell Commands,
ls : list files/directories in a directory, comparable to dir in windows/dos.
ls -al : shows all files (including ones that start with a period), directories, and details attributes for each file.

ls -alF: shows all files and its owners

cd : change directory · · cd /usr/local/apache : go to /usr/local/apache/ directory
cd ~ : go to your home directory
cd - : go to the last directory you were in
cd .. : go up a directory cat : print file contents to the screen

cat filename.txt : cat the contents of filename.txt to your screen

chmod: changes file access permissions
The set of 3 go in this order from left to right:
USER – GROUP – EVERONE

1 = –X  Execute only
2 = -W-  Write only
3 = -WX  Write and execute
4 = R–  Read only
5 = R-X  Read and execute
6 = RW-  Read and write
7 = RWX  Read, write and execute

Usage:
chmod numberpermissions filename

chmod 000 : No one can access
chmod 644: Usually for HTML pages
chmod 755: Usually for CGI scripts

chown: changes file ownership permissions
The set of 2 go in this order from left to right:
USER – GROUP

chown root myfile.txt : Changes the owner of the file to root
chown root.root myfile.txt : Changes the owner and group of the file to root

chown -Rf Username Foldername : Changes the owner of a directory and all files in it

tail : like cat, but only reads the end of the file
tail /var/log/messages : see the last 20 (by default) lines of /var/log/messages
tail -f /var/log/messages : watch the file continuously, while it’s being updated
tail -200 /var/log/messages : print the last 200 lines of the file to the screen

more : like cat, but opens the file one screen at a time rather than all at once
more /etc/userdomains : browse through the userdomains file. hit Spaceto go to the next page, q to quit

pico : friendly, easy to use file editor
pico /home/burst/public_html/index.html : edit the index page for the user’s website.

File Editing with VI ssh commands
vi : another editor, tons of features, harder to use at first than pico
vi /home/burst/public_html/index.html : edit the index page for the user’s website.
When in the vi program you can use the following useful commands, you will need to hit SHIFT + : to go into command mode

:q! : This force quits the file without saving and exits vi
:w : This writes the file to disk, saves it
:wq : This saves the file to disk and exists vi
:LINENUMBER : EG :25 : Takes you to line 25 within the file
:$ : Takes you to the last line of the file
:0 : Takes you to the first line of the file

grep : looks for patterns in files
grep root /etc/passwd : shows all matches of root in /etc/passwd
grep -v root /etc/passwd : shows all lines that do not match root

ln : create’s “links” between files and directories
ln -s /usr/local/apache/conf/httpd.conf /etc/httpd.conf : Now you can edit /etc/httpd.conf rather than the original. changes will affect the orginal, however you can delete the link and it will not delete the original.

last : shows who logged in and when
last -20 : shows only the last 20 logins
last -20 -a : shows last 20 logins, with the hostname in the last field

w : shows who is currently logged in and where they are logged in from.
who : This also shows who is on the server in an shell.

netstat : shows all current network connections.
netstat -an : shows all connections to the server, the source and destination ips and ports.
netstat -rn : shows routing table for all ips bound to the server.

top : shows live system processes in a nice table, memory information, uptime and other useful info. This is excellent for managing your system processes, resources and ensure everything is working fine and your server isn’t bogged down.
top then type Shift + M to sort by memory usage or Shift + P to sort by CPU usage

ps: ps is short for process status, which is similar to the top command. It’s used to show currently running processes and their PID.
A process ID is a unique number that identifies a process, with that you can kill or terminate a running program on your server (see kill command).
ps U username : shows processes for a certain user
ps aux : shows all system processes
ps aux –forest : shows all system processes like the above but organizes in a hierarchy that’s very useful!

touch : create an empty file
touch /home/burst/public_html/404.html : create an empty file called 404.html in the directory /home/burst/public_html/

file : attempts to guess what type of file a file is by looking at it’s content.
file * : prints out a list of all files/directories in a directory

du : shows disk usage.
du -sh : shows a summary, in human-readble form, of total disk space used in the current directory, including subdirectories.
du -sh * : same thing, but for each file and directory. helpful when finding large files taking up space.

wc : word count
wc -l filename.txt : tells how many lines are in filename.txt

cp : copy a file
cp filename filename.backup : copies filename to filename.backup
cp -a /home/burst/new_design/* /home/burst/public_html/ : copies all files, retaining permissions form one directory to another.
cp -av * ../newdir : Copies all files and directories recurrsively in the current directory INTO newdir

mv : Move a file command
mv oldfilename newfilename : Move a file or directory from oldfilename to newfilename

rm : delete a file
rm filename.txt : deletes filename.txt, will more than likely ask if you really want to delete it
rm -f filename.txt : deletes filename.txt, will not ask for confirmation before deleting.
rm -rf tmp/ : recursively deletes the directory tmp, and all files in it, including subdirectories. BE VERY CAREFULL WITH THIS COMMAND!!!

TAR: Creating and Extracting .tar.gz and .tar files
tar -zxvf file.tar.gz : Extracts the file
tar -xvf file.tar : Extracts the file
tar -cf archive.tar contents/ : Takes everything from contents/ and puts it into archive.tar
gzip -d filename.gz : Decompress the file, extract it

ZIP Files: Extracting .zip files shell command
unzip file.zip

Firewall - iptables commands
iptables -I INPUT -s IPADDRESSHERE -j DROP : This command stops any connections from the IP address
iptables -L : List all rules in iptables
iptables -F : Flushes all iptables rules (clears the firewall)
iptables –save : Saves the currenty ruleset in memory to disk
service iptables restart : Restarts iptables

Apache Shell Commands
httpd -v : Outputs the build date and version of the Apache server.
httpd -l : Lists compiled in Apache modules
httpd status : Only works if mod_status is enabled and shows a page of active connections
service httpd restart : Restarted Apache web server

MySQL Shell Commands
mysqladmin processlist : Shows active mysql connections and queries
mysqladmin drop databasenamehere : Drops/deletes the selected database
mysqladmin create databasenamehere : Creates a mysql database

Restore MySQL Database Shell Command
mysql -u username -ppassword -h webhost databasename < databasefile.sql : Restores a MySQL database from databasefile.sql

Backup MySQL Database Shell Command
mysqldump -u username -ppassword -h webhost databasename > databasefile.sql : Backup MySQL database to databasefile.sql

kill: terminate a system process
kill -9 PID EG: kill -9 431
kill PID EG: kill 10550
Use top or ps ux to get system PIDs (Process IDs)

EG:

Each line represents one process, with a process being loosely defined as a running instance of a program. The column headed PID (process ID) shows the assigned process numbers of the processes. The heading COMMAND shows the location of the executed process.

Putting commands together
Often you will find you need to use different commands on the same line. Here are some examples. Note that the | character is called a pipe, it takes date from one program and pipes it to another.
> means create a new file, overwriting any content already there.
>> means tp append data to a file, creating a newone if it doesn not already exist.
< send input from a file back into a command.

grep User /usr/local/apache/conf/httpd.conf |more
This will dump all lines that match User from the httpd.conf, then print the results to your screen one page at a time.

last -a > /root/lastlogins.tmp
This will print all the current login history to a file called lastlogins.tmp in /root/

tail -10000 /var/log/exim_mainlog |grep domain.com |more
This will grab the last 10,000 lines from /var/log/exim_mainlog, find all occurances of domain.com (the period represents ‘anything’,
– comment it out with a so it will be interpretted literally), then send it to your screen page by page.

netstat -an |grep :80 |wc -l
Show how many active connections there are to apache (httpd runs on port 80)

mysqladmin processlist |wc -l
Show how many current open connections there are to mysql
