A change in INET source

Receiving the erroneous packet during the waiting period for ACK or CTS indicates that there is a problem and you do not need to wait for time out and you can retransmit it again. We can check the erroneous packets and if they happens during the waiting period, cancel the timer and retransmit the packet. This is the standard. But in the current version, it waits for time out and does not care these erroneous packets.

You can find the patch here:

A different approach to change MySQL root password in Ubuntu Server

A different approach to change MySQL root password in Ubuntu Server

The other day I was having a problem with the MySQL server on my Ubuntu machine. After connecting to mysql server in php, I could not select a database. The error was: Access denied for user @localhost to database foo. I did specify the user being root, but it keept saying I dont have permissions with the user (anonymous). Reinstalling mysql didnt do the job. So, lets delete the user .

1. Stop the MySQL Server:

sudo /etc/init.d/mysql stop

or

sudo service mysql stop

2. Start the mysqld:

sudo mysqld --skip-grant-tables &

Press CTRL+C (^C) to be able to enter the new command.
3. Login to mysql server:

sudo mysql -u root mysql

4. Delete the user :
If you enter the following command:

SELECT USER(),CURRENT_USER();

you will see that the users are different, one being and the other root.
Delete the anonymous user:

DELETE FROM mysql.user WHERE user = ;

Update root password (optional, if you know it):

UPDATE user SET Password=PASSWORD(1234) WHERE User=root;

5. Stop mysql server instance:

ps aux | grep mysql

On the second column, you will find the PID (process id) of mysql server. Kill it:

kill 20233

6. Start the usual mysql server:

sudo service mysql start
